Hi,

I tried running the samples by downloading them which is provided in InfoCenter under the section
'Embedding the Reporting Engine into a Java applocation'.

I could execute a report (.prpt file) which is developed in Report Designer from within
a java application to generate the output file which is what Sample1 does.

But I couldn't find success in executing an interactive report (.prpti file) from within a java application.

Here is the exception stack trace I have been getting :

I checked in the infocenter and in Pentaho forums whether it is possible to execute a .prpti file from within a java application,
But couldn't find the answer. Only it says that a .prpt file can be executed.
Is there a way to execute .prpti file from within a java application for generating the output just likes with .prpt file?

Thanks and regards,
Raman Kumar.

Most likely, your classpath is incomplete. Use the SDK to get a sample module that includes a full classpath ( https://github.com/tmorgner/pentaho-reporting-oem-sdk/tree/master/sample-use-full ).

At that point, you will be able to simply point the code in this particular sample to your prpti file, and it will run.
