Adapter to RQM is not recognizing the third party library

Adapter to RQM is not recognizing the third party library POI-3.5

Hello,

I am getting the error "java.lang.NoClassDefFoundError" when executing an script by using RQM/RFT-Adapter.

This is not happening when I execute that script directly from RFT environment, only when executing from RQM/RFT-Adapter.

I have added the "poi-3.5-beta5-20090219.jar" as external jar on RFT Java build path.

The error is:
{
* java.lang.NoClassDefFoundError
* org.apache.poi.poifs.filesystem.POIFSFileSystem
* Script Name = TestCases.REG_REGRESSION08
* Script Id = TestCases.REG_REGRESSION08.java
* Line Number = 75

}

How can I make this external library recognizable from RFT adapter (Adapter to RQM)?

Thanks in advanced, I really appreciate your help.
