Hi all,

I tried to run a report using the MyEclipse tutorial http://www.myeclipseide.com/documentation/reporting/quickstart/

and when I try to run it on a web browser, I have this exception :

Code:

org.eclipse.birt.report.service.api.ReportServiceException: Error happened while running the report; nested exception is: java.lang.NoClassDefFoundError: org.eclipse.birt.report.data.adapter.api.DataSessionContext

The derby server and MyEclipse Tomcat are both running.
I retrieve the data from an Oracle database.

I'm using Eclipse 3.3 and MyEclipse 6.5.1 on Linux (Ubuntu).

Any idea about what is going wrong ?

thanks for your help.

Can you go to MyEclipse > Installation Summary > installation Details and paste the information here for me.

When you setup MyEclipse Reports with MyEclipse, did you get any errors?

Can you go to MyEclipse > Example-On-Demand and try running the MERSimpleReportExample. Do you face the same issue?

here is the installation summary :

I installed Eclipse 3.3 and MyEclipse 6.5.1 today.
I just untared the eclipse3.3, run it and then I when to Help>Software Update>find and install and I pointed to the MyEclipseDiscoveryArchive.zip

the report feature was available then.

I will try to run the MERSimpleReportExample and see what happens.

Yes, the MERSimpleReportExample generates exactly the same exception.

If you go to File > New > Project > MyEclipse, do you see the Report Development > Report Web Project option in there?

Yes, I can see it and I used it to create my report.

I have also another issue : I can see nothing in the Property Editor thumbnail even when I select the "table" object.

after restarting with a new workspace, it's finally working in MyEclipse browser (the property editor too).

But I still have an exception when I type the url in an external browser (no stack trace is displayed). It's just saying : version mismatch.
Do you know why ?

thanks.

Can you paste the entire exception here for me. I feel you might have to switch to Java 1.5. I'll take a look at the exception and let you know.

It's working on any other browser than Firefox 3. And when I have this exception on F3, I can only see the message :
Exception : version Mismatch

and the stack trace is empty.

Is there any additional information about this error recorded under <workspace>/.metadata/.log file?

no, nothing.
