My coleague have installed fresh installation of NWDS SPS15 and the same example on his installation work fine. All building proccesses are successfully executed. I tried it several times, everytime same result. I tried to use fresh workspace, tried to delete whole content in ./dtc.

I compared every file with coleague installation. But no success. I am running out of ideas what should I do with it.

If anyone was facing similar problem or have any idea. I will be glad to read it.

Thanks

Hi Miroslav,

I did not face with this problem, but try to build with jsdk 1.4.2_06.

Best regards,

Aliaksei.

Hi Aliaksei,

I already solved that problem. Yes I was using j2sdk1.4.2_08 but had also installed jdk1.5. I was building with jdk1.4 and also ant build tools was from jdk1.4, then I had have noticed that my NWDS is starting using jre1.5, after change this, everything works.

Thanks for post.
