I'm trying to use some external jar with web dynpro java DC project.
I'm adding jar file with properties->java build path->add external jars.And i execute context menu source->organize import then it finds and puts related classes in import section.
When i use dc -> build it deletes jar and generates some class missing error.
I used external library project and i add compilation and assembly item into used DC's but when dc->build it generates same error again.
What must i do?
