problem using external jars in my java component

[Former Member]

Hi Guys,

I just wanted to ask how to properly reference an external jar to a java dc. I already have an external library dc which contains my external jars and also compilation and assembly public parts, a j2ee library which has the assembly public part of the external jars that is deployed to the server, a java dc which has the compilation public part of the external jar.

My problem is whenever I trigger a method of the java dc in my webdynpro dc I'm having an exception. weird thing is when I put the whole method from the java dc to the webdnypro dc it functions well. So I'm thinking if the interaction between my java dc and j2ee lib dc has to do with this maybe I'm missing some configuration.

need your insight on this one.

Thanks,

Hi Arun,

I'm using Netweaver 7.0, I already did the steps given there except that instead of j2ee enterprise application I used j2ee server component library. I have no problems on design time its just that whenever I trigger a method of the utility dc to the webdynpro dc I'm having a runtime error.

Have you defined the required library reference in your Web Dynpro DC?

Yup, but didn't worked.

I changed the utility from plain java project to j2ee component. problem solved

Thanks
