Elected as Apache Axis2 Committer and PMC

It has been a long time, when i started to contribute to Apache Axis2 . As my first contribution to Apache Axis2, I have implemented Axis2 JDK 5 Enum support,. Here is my blog post which explain how to consume that feature. From that onwards I continued my contribution for Apache Axis2 as not only in the Axis2 core , I also contributed to Apache Sandesha2 which is an Axis2 module that provides reliable messaging capability.

I did my GSOC 2012 with Apache Axis2 in improving the JSON support of Apahce Axis2. As an outcome of this my mentor Amila Suriaarachchi  and myself could able to introduce a new approach to convert native a JSON message to XML bidirectional transformation mechanism without any data loss, and it supports namespace too.

Considering the contribution i have done so far in both coding and user mailing list, I have been elected to be an Apache Axis2 Committer and PMC. This is a great achievement for me and I am very much happy about it.

If you find a jar which is not in any maven repository. But you need it to build you maven project you can first install that jar to you local repo using mvn install:install-file .

e.g: java-gmail-imap.1.4.4-gm-ext-0.6.jar is not in any maven repository therefore i need to install it on my local repository, run following command in terminal

mvn install:install-file -Dfile=/path/to/java-gmail-imap.1.4.4-gm-ext-0.6.jar -DgroupId=com.google.code -DartifactId=java-gmail-imap -Dversion=1.4.4-gm-ext-0.6 -Dpackaging=jar

Maven doesn't run all tests but print build success message and quit

When i am writing an end-to-end test to Apache Axis2 JSON support(End-to-end means it up a Axis2 server and deploy a service which is created on a fly, on it and test with that service and stop Axis2 server end of tests). Here i faced a problem that when i run the test using maven(mvn test) it runs isolation test(test particular functions of a class) upto my end-to-end test. it print build success message in terminal console and quit.

OOPs what happened to other isolation tests :( . then i debug the code and see are there any test failure in my end-to-end test but, believe me end-to-end test pass all tests and successfully execute @After method which is tearDown() method too. After that it return build success message and quit. How i can find a error when it says build success :) . Finally i found the solution for that. solution is add <forkMode>pertest</forkMode> to the suirefire maven test plugin. Then every things ok , it runs all test including above end-to-end.

Install Netbeans 7.2 in Ubuntu 11.10

When I try to install Netbeans IDE by downloading netbeas*.sh file from the Netbeans website and run it in terminal, it say installation is not completed please find the log file and try again. I tried with serveral netbeans.sh files , even several versions but result is the same. After that i tried by giving path to javahome using "sh netbeans*.sh  --javahome /path/to/JDK/home ". But still i get the same error message.

Somehow I could able to solve this issue using pack which provided by Oracle. In that pack they have bundle JDK and Netbeans 7.2 together. You can find it in JDK 7u6 with Netbeas 7.2 post published by Oracle. You need to do is accept the license agreement and download it. Then you can run it using sh command as usual.

Thanks,
Shameera.
