Jooming with Joomla

The amount of work needed to get a site up and running especially the front end XHTML design part i A LOT.
I came across one excellent CMS solution which can very well be used to develop plain vanilla websites.
 The results are really amazing.
I feel it is much better than Drupal in terms of ease of use and its rich admin features..


It has millions of plugins and themes to choose from. Once you get the knack of placing the plugins and 
using themes into your site, virtually you can achieve amazing results with very less coding effort.

Here are a few notes for Joomla 1.5:

Positioning in CSS is the key for each module. You need to understand the positioning after reading the CSS.
The module name is the key in css that needs to be mentioned in the new module's postion attribute. Eg: left, top, right, user3, use4 , etc

To add a search box in home page
 Extensions --> Module Manager -->new--> search

To add a menu
 Extensions -->Module manager --> new --> menu.
   Be careful to give the position of the menu as the one in HTML theme...eg: 

News in home page
   Define a section news, then a category for news. Add article for this category.
   Extensions-->  Module manager --> new --> news flash
   Choose the category which holds articles for news..thats it.

Contact us 
   Menus --> new --> Internal link--contacts

Gallery
  Download a plugin extension like MorfeoShow. Add this module and configure..

Spring MVC

Spring has many controllers.
SimplefFormController is an interesting one to work with.
I try to disect this in this blog posting.

Lucene

Lucene is an excellent text search engine.
Solr a sub project of lucene provides web based interface handling XML requests and executing XML commands .
"Solr is more of a general-purpose search server, and it assumes you already have structured data (like   catalog data, music collections,etc)."
Nutch again a sub project of lucene is an excellent web crawler.
"Nutch is more like an open-source google... it's for crawling, converting, indexing, and searching websites."
Assuming you have an existing J2ee application with struts and hibernate. The following major components/classes would be required if we consider to use lucene or solr:

1. Search Index writer:  This will use existing hibernate methods/APIs to read the records (which need to be searched) and create lucene indeces. The index can be stored  on the disk or in a database via JDBC. Lucene calls these index records as documents and will have relevant information to display in search result.

 2. Search index reader: This will read the index stored(on disk or database by step 1.) and return the search result. There is no hibernate method calls involved as the lucene index is separate from database. To display the search result, the struts action classes would need to be altered/added. However on click of the search result for details of the record, the existing struts/hibernate(if it is available)  functionality will be used to display the details of a record.


Basically you can think of it as a search engine implementation(like google) where you index the records(like websites) and search results will contain only the basic information. The detailed information is delivered on click of a link on search result.



Coming to Solr, this is basically a web service wrapper on top of lucene. Under the hood it also builds lucene index. The advantage of Solr being it is web service based so it is easy to sync index in a distributed environment. Also it provides caching, index syncing etc out of the box.



Gotchas and Tips:
Sorting:
 Need to maintain a duplicate field which is NOT_ANALYZED.
 **** sorting is case sensitive *****
 sorting field value can be having a fixed max length say 20 ... this improves performance.
Indexing:
 Analyzer used for indexing and searching should be the same.
 StandardAnalyzer can be extended to have HTMLStripReader and ISOLatin1AccentFilter.

Fedora 9 on lenovo 3000 N200

My lenovo 3000 N200 was sick last week.
I have a dual boot win xp and fedora 9 setup. It worked for a few months..Then the agony...
The laptop would shutdown suddenly, or while booting and sometimes it even would wake up by itself although it was shutdown (like a zombie). Scary !!.

After some initial struggle and making dozens of calls to Lenovo support centre, a techie told me that N200 has a problem with BIOS and I had to reset it to defaults.

Well I did it. Guess what - my windows xp BSOD started showing up on startup.
Fedora 9 also was crashing now.

Luckily I had fedora 9 setup cd and after a re-install things were normal with fedora. However the windows BSOD persists.
Tried to get hold of a windows XP cd, but unfortunately though I am able to but up with win xp, it simply says setup is now checking.... and simply hangs with Black screen...Seems like it's not able to detect HDD

Anyway I got fedora 9 with internet working fine.
However I had a problem with sound. As per a forum i setup sound and it worked like a charm. The fix was:
In /etc/modprobe.d/alsa-base add a line
options snd-hda-intel model=lenovo.
Restart, voila sound's good.

Next with fedora, i was not able to play mp3,
After some searching around, I got a cool tool for fedora 9, it is named easylife - an opensource project. This installs all the required software on fedora at one go. Like skype, adobe, flash, etc. Everything is taken care under the hood.
next flash on fedora was not working..
Had to checkout if it was 64 bit installation using $uname -a

Yes it was for me and hence followed below instructions:

Installation on Fedora 64-bit

The following steps are required for Fedora 64-bit users.

First install the Adobe YUM repository, as stated above:

[mirandam@charon Download]$ sudo mkdir -p /usr/lib/mozilla/plugins
[mirandam@charon Download]$ sudo yum install nspluginwrapper.{i386,x86_64} pulseaudio-libs.i386 libflashsupport.i386
[mirandam@charon Download]$ sudo yum install flash-plugin

[mirandam@charon Download]$ sudo mozilla-plugin-config -i -g -v

This was adapted from the Fedora 9 Release Notes.

NOTE - PulseAudio - I was able to hear sound properly in both Gnome and KDE in Firefox when PulseAudio was enabled.

I'm yet to try this link to revive win xp.. http://forums.lenovo.com/lnv/board/message?board.id=N_Series_Lenovo_3000&thread.id=269

Jquery

It is :
* simple (include a javascript into ur existing page and you start playing with Jquery),
* light weight(core is just 20KB), pluggable/ extensible(thousands of plugins) and
* easy to use (implicit event handling, expression evaluation and function chaining to name a few).

Client-side
Also a jquery-form plugin( http://malsup.com/jquery/form/ ) makes HTTP form post much more easier.
This takes care of marshalling the HTML input fields automatically , make a form post and deal with the HTTP response.

Server-side
There is some work done already on (spring MVC + jquery) http://www.infoq.com/articles/First-Cup-Web-2.0-Joel-Confino
Tried a prototype using this and jquery-form. Actually it works well with Xstream and Jettison mapped driver .
Also converting the existing spring MVC controller to have AJAX capability is just a matter of setting a custom Json View instead of existing Velocity
view.

Data can be transferred from browser to server in either of the format:
JSON(Java script object notation) or XML.
JSON is simple as it gives you a java like object graph and is more popular in open source community.
However it lacks XML flexibility (like having attributes,etc)

Obviously, having an IDE for jQuery would make development easier. Searched around for an IDE with JS code completion and debugging capabilities.
There are few of them to evaluate - Aptana and Spket IDE.

Apache commons usage

There are many good ready to use commons libraries from apache. These should have been in JDK.
Often we fail to use their feature and spend time and effort to reinvent the wheel. I make an effort to brief the practical usage of these libraries here:

1. commons-lang

public boolean equals(Object obj) {

      if (this == obj)
          return true;

      if (!(obj instanceof Institution))
          return false;

      Institution rhs = (Institution) obj;
      return new EqualsBuilder()
              .appendSuper(super.equals(obj))
              .append(this.getSubscriberId(), rhs.getSubscriberId())           
              .isEquals();
  }
  public int hashCode() {

      // Don't be tempted to use reflection here - Hibernate throws a major wobbly :(
      return new HashCodeBuilder()
              .appendSuper(super.hashCode())
              .append(getSubscriberId())
              .toHashCode();
  }
  public String toString() {

      // Don't be tempted to use reflection here - Hibernate throws a major wobbly :(
      return new ToStringBuilder(this)
              .appendSuper(super.toString())
              .append(getSubscriberId())
              .toString();
  }

2. commons-digester
  -This provides a wrapper to parse XML.
    Usage:

      Digester articleDigester = new Digester();
      articleDigester.addObjectCreate("art", ArticleXMLTO.class);
      articleDigester.addCallMethod("art/fm/bibl/source", "setSource", 0);
      //setSource is a setter in ArticleXMLTO

      articleDigester.addCallMethod("art/fm/cpyrt/year", "setCopyrightYear", 0);
    
      //for publication date.
      articleDigester.addCallMethod("art/fm/history/pub/date/day", "setTempPublicationDay", 0);

//For passing params to methods..
trialDigester.addCallMethod("MRCT_RECORD/CONTENTS/TITLE/DATA", "addField",2 );
trialDigester.addObjectParam("MRCT_RECORD/CONTENTS/TITLE/DATA", 0, "FIELD-NAME");
trialDigester.addCallParam("MRCT_RECORD/CONTENTS/TITLE/DATA", 1);

    
      //For encapsulated objects
      articleDigester.addObjectCreate("art/fm/bibl/aug/au", AuthXMLTO.class);
      articleDigester.addCallMethod("art/fm/bibl/aug/au/fnm", "setFName", 0);
      articleDigester.addCallMethod("art/fm/bibl/aug/au/mi", "setMName", 0);
    
      //for a set of objects
      articleDigester.addSetNext("art/fm/bibl/aug/au", "addAuth");
      //addAuth method adds the object to the list.

      articleXMLTO = (ArticleXMLTO) articleDigester.parse(xml);

Simpler than dealing with DOM or SAXing isn't it.

Java Classpath issues

The most difficult problem to solve from a distance... But if we look closely its a piece of cake.
Many developers spend so much time in fixing this issue. Lot of frustration and anger. What they dont spend time on is finding how the classpath and class loading is done in java. Once you know it, you are done.

I herewith try to log a list of java classpath issues:

1. Junit cannot load classpath resource:
The ideal solution as I know is to put the resource along with the junit class(unless it is not reused across). Then load the resource using MyClassTest.class.getResourceAsStream("articles.xml");

This is a simple and elegant solution rather than hardcoding or putting a relative path , which are bound to fail in different environments.

AJAX - What javascript can do..

AJAX is asynchronous javascript and XML. AJAX in it raw form is difficult to build rich applications. Many frameworks are developed hence. As javascript is object oriented, building a framework on it is easy. Something like a JDK with packages can be built and maintained easily.. Though AJAX was for XML, HTTP responses and JSON(kind of protocol) are supported. The following are in the market:

1. GWT -by google. Java to javascript compiler makes it easy for java developer.
2. Zk -very powerful and simple.
3. DWR -simple
4. Dojo - Excellent.
5. Yahoo kit - dont know
6. Ext JS
7. Jquery
8. More.....

Setting up the environment for these AJAX development is always a pain. Will write more in future on this.

Speed typing tips.

Here are a some basic tips, summarized from various typing tutorials and lessons. These tips are useful for taking tests as well as everyday keyboarding:

• Tap on each key crisply but lightly. If you use minimum force (don't bang on the keys), your fingers will move faster.
• Type as quickly as you are able, but don't "try" too hard or force your speed or you'll make many mistakes.
• Relax!
• Use proper posture, sit upright.
• Keyboard/monitor positioning: your wrist, elbows and keyboard should be on the same horizontal plane, and at a 90 degree angle to your upper arms.
• The top of your screen should be near eye level.
• Stretch your wrists and fingers before starting a typing test (don't laugh, it does help!).

I love log4j

Logging is a very useful thing. Without this most of our java softwares are like black boxes.
The major problems we face is setting up the log4j. Also trying to decipher the cryptic clues is annoying, like say log4j WARNING No appenders could be found. Who has time to fix these issues..
Well it pays of well if you fix it as I said u cant fix a software problem without seeing what is happening inside. It will be like the movie HAPPENING(Should have been what is happening) ...


A few tricks to get the log4j setup:
Passing VM arguments
-Dlog4j.configuration=file:C:/development/projects/webapp/target/classes/log4j.properties

-Dlog4j.debug=true .....Excellent option to know what is happening inside log4j.


commonly used log4j.properties is below:
---------------------------------------------------------------------------------------------
log4j.rootLogger=debug, stdout, R

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

# Pattern to output the caller's file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n

log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=example.log

log4j.appender.R.MaxFileSize=100KB
# Keep one backup file
log4j.appender.R.MaxBackupIndex=1

log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n

Working with microsoft DLL,ODBC connection and IIS for a java developer

DLL's are dynamic link library. They are like .jar files in java.
Normally the error we get in dll's are due to dependency on other dll's. Tools like dependency walker and dll explorer come for the rescue.

To register a dll use(like loading jars to JVM)

regsvr32 [DLL path]

also
rundll32 [dll path]

IIS

• IIS is web server provided by microsoft.
• For the IIS we need to configure the components.
• For this, go to control panel-- admin tools --computer mgmt --component services -- computer--my computer -- COM+ applications -- new application --Add users and imports ...Thats it the IIS will pick it up...

To unit test a package in the dll create a x.vb file with the below code:
set testobj = nothing
set testobj = createobject("IMPORT.Job")

msgbox "PR: " & testobj.PathRemoved("C:\development\miscellaneous\COM\testmdb")

if(testobj.DeleteFile ("C:\development\miscellaneous\COM\test.mdb"))Then
msgbox "Deleted your file!"
End if


--------------------------------------------------------------------------------------------------------------
Oracle connection through microsoft:
update \oracle\product\10.2.0\client_1\NETWORK\ADMIN\tnsnames.ora
Go to control panel-- datasourc(ODBC) connections --add new connection in first tab.Select database name and auth details.Do a test connection. Thats it

/>mvn archetype:create -DgroupId=[com.biomedcentral] -DartifactId=[archetype-spring-jar] -DarchetypeArtifactId=maven-archetype-archetype

Update the archetype [archetype-spring-jar]\src\main\resources\META-INF\maven\archetype.xml
Keep all the relevant resource in the [archetype-spring-jar]\src\main\resources\archetype-resources\... and update the archetype with its reference.

Install the archetype project itself:
/>mvn install

Now time to use this project generator:
mvn archetype:create  -DarchetypeGroupId= -DarchetypeArtifactId= -DarchetypeVersion= -DgroupId= -DartifactId=


This is amazing...From an existing architecture u can clone yours ...

A sample command using above for spring hibernate is below:
#mvn archetype:generate -DarchetypeGroupId=com.webtide -DarchetypeArtifactId=maven-archetype-SpringJpa -DarchetypeVersion=1.0 -DgroupId=c
om.my.package -DartifactId=ImageLibraryCategoryManager

mvn org.apache.maven.plugins:maven-archetype-plugin:1.0-alpha-7:create -DgroupId=com.my -DartifactId=springmvc-hibernate-app -DarchetypeArtifactId=appfuse-basic-spring -DarchetypeGroupId=org.appfuse.archetypes

A bit on Maven Plugins:
  1. maven-dependency-plugin : http://maven.apache.org/plugins/maven-dependency-plugin/
      Very useful for copying dependency jars for a standalone app,etc.
