NWDS it's Installing and Configuring

1. Download and install JDK 1.6 from here:


http://www.oracle.com/technetwork/java/javase/downloads/jdk-6u26-download-400750.html

2. Copy the file nwds-extsoa-7.3-SP00-PAT0000-win32.zip from:

<your download location>\51039309\DATA_UNITS\JAVA_IDE
\distros\com.sap.netweaver.developerstudio.distribution.complete.extsoa \8.30.0.101020102100
to a convenient folder.

3. Extract the content and you will have a folder with name “eclipse”.

4. Launch the Netweaver Developer Studio from folder eclipse, you may want to create a shortcut on the Desktop.

5. If you haven’t maintained JAVA_HOME property or if it’s pointing to some other java version, eclipse will complain about it. In the dialog window locate the JDK 1.6 installation. Path to JDK 1.6  should be something like

C:\Program Files\Java\jdk1.6.0_25\bin

6. Restart the NWDS after this and select a suitable workspace.

7. Set the run time engine in NWDS, by going through the menu path:

Window->Preferences->SAP AS JAVA

Your NWDS is setup now for basic development tasks. However it’s my personal preference to always install the two very useful plugins (JAD Eclipse and Jar Class Finder) before I actually get into any development. Although we won’t be needing them for the example discussed in this blog, they are always handy.

Installing JAD Eclipse Plugin

1. Download JAD from here:
Jad 1.5.8g for Windows 9x/NT/2000 on Intel platform
Extract it and save it in a suitable folder.

2. Download the JAD Eclipse plugin from here
JadClipse – Eclipse plugin
JADClipse web site

3. Step by step instructions to how to install, configure and use JAD Eclipse:
Jadclipse is eclipse plug-in that integrates Jad (Java decompiler) with Eclipse.

• First you require Jad for decompiling java files. You can find a list of mirrors on this site where you can get JAD for various platforms. Download it and unzip into any folder on your hard drive.
• Next download the Jadclipse plug-in jar file from here and place the jar file in your eclipse plugins folder
• Restart your eclipse. If eclipse didn’t recognize the plug-in then launch eclipse with -clean flag:  ”eclipse -clean”
• Configure the path to the Jad executable in eclipse under Window > Preferences… > Java > JadClipse > Path to Decompiler.
• Set the full path of the jad executable, e.g. C:\Program Files\Jad\jad.exe
• Go to Window > Preferences… > General > Editors > File Associations and make sure that the JadClipse Class File Viewer has the default file association for *.class  files.

File association

Now everything is done. If you want to view the source for any class then simply ctrl+click on that class then the source for that class will be showed in your eclipse editor.
