Hi Experts

I am developing an application with JasperReports based in this links:

In my application i have just one difference, i created an external library DC to put the jasperreports jar, and add as depenedent in my web dynpro project.

when i deploy and run the application i get some erros like this:

net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file:
D:\usr\sap\DC1\J00\j2ee\cluster\server0\Relatorio_teste_WD_1269440919163_475697.java:4: package net.sf.jasperreports.engine does not exist

- The library app is already deployed.

- I use NWDS 7.1.EHP1 SP04

- When i test local in standalone app, the same code works.

I apreciate your help.

Hi Marcos,

I think there is some problem with the external library and used dependacy...

I look like WD application not able to find rquired jar for that. Please check the dependancy.

I did this steps to create a External Library:

1 - put the jars files in library Folder.

2 - publish as archive with compilation and with assemble for each jar.

3 - build and deploy it.

4 - Add the external library component in web dynpro compenent in it dependencies.

This is what i did. There is some another steps, or i did something wrong?

When i use the API of jasperreports in my code, works fine. I can find the classes. But qhen i deploy and run WD application, i get that error...

Marcos.

Hi Marcos,

Even I am stuck with the same issue.

Did you get any solution to this ?

Usage of jars in Web Dynpro for CE seems to be a huge deal !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1
