Activation failed: Missing external jar

Question

Hi,
I'm using an external jar in my WebDynpro development for ESS. I placed this jar file in the lib folder. Everything works fine when deploying to the development server directly.
During activation, i got the error which describing the imported classes from the jar file cannot be found. I'm confirmed this jar file was uploaded into the open activity prior to the activation.
How to solve this problem?
Any help would be highly appreciated. Thanks.

Hi julius,
if you want to use a class in a jar file in your WebDynpro Development DC, you have to do the following steps:
1) create a external library component , copy your jar file into the library folder
2) creating two public parts one of the type assembly the other one of the type compilation
3)create a j2ee library component and use the Public part of type assembly from step one as used component. Build and Deploy that component (sda file) to your server.
4)In your WD DC use the PP from step 1 of type compilation, build the DC -> then you can use the classes of yor jar file.--> Organize Imports
5)Last step: navigate to the properties of your WD project-> select Web Dynpro References -> select Library references and perss add. Enter the name of the j2ee library component ( this is for runtime dependency)
