Hi,

Its clear from the error environemnt variable JAVA_HOME is not set.

"Perhaps JAVA_HOME does not point to the JDK"

If you are using the Ide set this using

Window->Preferences->Java->Installed JRE's

Hi Sudheer,

Give a Try with this,

- Right Click on your DC and choose Properties,

- Then Java Build Path,

- Click on "Libraries" Tab,

- Click on "Add Library" tab (positioned on right hand side),

- Choose JRE System Library, click Next

- In JRE Drop down choose the installed j2sdk (eg : (default) j2sdk1.4.2_12) or create a new one if this is not available in dropdown.. and click finish...

Thanks & Regards

Hi all,

thanks for the effort.

i have solved it by un-installing and re-installing the NWDS as it was urgent and as a last resort.

Hi,

You can set the JAVA_HOME in MyComputer.

1. Right Click MyComputer

2. Select Properties

3. Select Advanced

4. Select Environment Varibles

5. Select JAVA_HOME if available or select new and enter JAVA_HOME

6. In Varible value give the path of your java folder like C:\j2sdk1.4.2_09
