As part of the installation process, for NetBeans, git is installed. git needs to have the proxy settings to be configured properly before it is functional. Use below command to setup the proxy git config --global http.proxy http://<ip>:<port> When integrating with ionic using the below command to download ionic npm install -g ionic To start an ionic app, use command ionic start <AppFolder> If you are behind a proxy you need to set the PROXY environment variable as below set PROXY=http://<ip>:<port> Below is a good tutorial for building a cordova-ionic app https://www.youtube.com/watch?v=sCnGSOaaZFo Tutorial for ionic apps using jax-rs http://ccoenraets.github.io/ionic-tutorial/create-angular-service.html Tutorial for Angular JS https://docs.angularjs.org/tutorial/step_11 http://www.toptal.com/angular-js/a-step-by-step-guide-to-your-first-angularjs-app

While deploying my EAR which included a WAR, I was getting the following errors. While searching on the net for possible solutions to the issue, came across a post which indicated that the following setting for the domain was the cause for the same. The setting needs to be deselected. I tried the below url for steps to disable the setting for the domain that I had already created. http://stackoverflow.com/questions/12219782/how-do-you-turn-off-sip-support-in-weblogic-server-12c But that did not help. I then created a new domain and ensured that the setting was unchecked. This resolved the issue.

Check the discussion below for a cool syntax highlighting option for your technical articles on blogspot. http://stackoverflow.com/questions/10335463/how-to-setup-syntax-highlighter-on-blogger One of the articles on this sites has made use of this option http://javatechreference.blogspot.in/2014/08/java-agent.html

Starting with JDK 1.5, the javaagent feature has been around which provides for a hook to get access to the classes as they are loaded and consequently do instrumentation of the class to serve your purpose. This along with Javassist will allow you to achieve some useful tasks like enabling specific debugging etc. Below are some useful links for the same http://www.csg.ci.i.u-tokyo.ac.jp/~chiba/javassist/tutorial/tutorial.html http://blog.javabenchmark.org/2013/05/java-instrumentation-tutorial.html https://today.java.net/article/2008/04/22/add-logging-class-load-time-java-instrumentation I used to face issues related to the agent class not been able to find javassist related classes. To tackle this you can add an index file to the agent jar like below. jar -i agent.jar lib\javassist.jar and ensure that during deployment the javassist.jar file is in the lib folder which itselfs exists in the same directory as the agent jar.

Findbugs provides for a quick method of doing static code analysis. It can operate in a stand alone mode and integrates well with eclipse as well. More information on this can be found at http://findbugs.sourceforge.net/ The installation comes with a number of built-in detectors. Additional detectors can be found at http://fb-contrib.sourceforge.net/ While these detectors are useful, the real power of FB can be unlocked by writing a custom detector for you code. Below is a step by step tutorial that you can refer to for writing a custom detector for your code. https://code.google.com/p/findbugs/wiki/DetectorPluginTutorial http://www.ibm.com/developerworks/library/j-findbug2/ To write your own detectors you would need to know the byte code being generated for your classes and then based on those patterns write a detector which will serve your purpose. One good plug-in to view the byte code for your classes is the Dr. Garbage Byte Code Visualizer. It is available as a eclipse...
