EOFException while loading compiled report teplate with JRLoader.loadObject(InputStream)

[maridion]

Hi,

I'm using jasperreports-4.0.0.jar and JBOSS EAP 6.1 and I'm experiencing problems while loading compiled report template.

Any help would be appreciated.

I have my report templates packed into a jar and I try to load it with JRLoader.loadObject(InputStream is):

 InputStream is = myClass.getClass().getResourceAsStream(compiledFileName);

            jasperReport = (JasperReport) JRLoader.loadObject(is);

myClass is in same jar as template.

When I run this code I get exception:

Finally found the problem.

 

In case that anybody else will have same situation I'll add explanation.

Report template was compiled with IBM's java, although file was created it was not correct so it could not be restored to JasprReport instance. 

When switch to Oracle's Java problem was gone.
