Need : How to include an external jar in a Development Component Project

[Former Member]

I know this issue has been addressed in a previous discussion thread, however none of the answers given worked for me.

I have created a Development Component Project of type Web Dynpro. I need to access an external jar. I copied the jar to the lib directory of the project, and created a reference to it in the build path. The WebDynpro app builds correctly, but when I deploy it and try to run it I get a "NoClassDefFoundError" on objects in the referenced jar file.

However, if I create a new Web Dynpro project (as opposed to a new Development Component project), everything works fine.

Any detailed, step-by-step help for how to solve this problem would be greatly appreciated.

Hi,

I am not sure about your previous threads. But i am referring to external jar as follows.

1. Create a DC of type Java.

2. Create a Public part and include the external jar

in the public part.

3. Create a webDynpro DC and refer to the public part of

the above java project.

Thanks for responding, but I need very explicit help on this as I am not succeeding.

1. Create a CD of type Java - I have done this.

2. Create a Public part and include the external jar

in the public part.

- Exactly how do I do this? I would greatly appreciate

a step-by-step walkthrough.

- After doing this do I need to build the project?

- Do I need to deploy it to the J2EE engine? If so, how?

3. Create a webDynpro DC and refer to the public part of

the above java project.

- After doing this, do I still need to have a reference to the original JAR file in the build path?

Hi,

Refer the forum "Using External JARs in a Web Dynpro Project"

https://www.sdn.sap.com/sdn/collaboration.sdn?node=linkFnode6-1&contenttype=url&content=https://

This should solve your problem.

Tried using the instructions from the link - didn't succeed. I really need an idiot-proof step by step guide how to do this, of the type:

Click "File -> New -> Project.."

with every step fully detailed.

Thanks in advance,

Walter

Please continue in the other topic and close this one. There's no need to have two topics on the same subject.

Thanks in advance!
