Spring-driven Jasper compilation fails?

**garyshea** · Sep 13th, 2005, 11:11 AM

I'm running Spring MVC with Jasper reports in tomcat 5.0.28. Spring initiates the compilation of my jasper reports .jrxml file. I get a stack dump (below) saying that compilation failed, and the top couple frames are from jasper code. In addition to the stack dump, there is a large amount of error output that appears to be from a Java compiler (also below). All of these errors complain of being unable to find jasper reports classes, classes which are right there in the jar with the Jasper compiler. I've tried placing the jasper jar in tomcat's common/lib directory, which did not help.

the evidence....

Hi Gary,

I came across a similar problem yesterday. Analysis showed that the compilation process really doesn't have anything to do with the servlet container. Instead, the code spawns a new compilation process using the system classpath.

So the easy fix would be to add the jasper reports jar to your system classpath. A (better) idea is suggested by this developerworks article: http://www-128.ibm.com/developerwork..._olivieri.html. Before the compilation add some code somewhat similar to the following:

Code:

// Set the class path
ServletContext context = getServletContext&#40;&#41;;
System.setProperty&#40;
        "jasper.reports.compile.class.path",
        context.getRealPath&#40;"/WEB-INF/lib/jasperreports.jar"&#41; + System.getProperty&#40;"path.separator"&#41; + context.getRealPath&#40;"/WEB-INF/classes/"&#41;&#41;;

The only thing is that the code that loads and compiles the report is invoked in AbstractJasperReportsView.initApplicationContext() . I'm not using Spring MVC, so this isn't a problem for me, but you'll need to find a hook or some other way to set that property before this is invoked.

Hope this is of some assistance.

Regards,
Geoff

Geoff -- Thanks, that makes sense. I was wondering if the compilation was happening in a separate JVM, but I had no idea how to communicate the classpath requirement to it. Now I do!

Hi To all,
I am using Spring Framework and Japser Reports. I am able to succesfully compile the JasperDemo project which is present on CVS of Spring.

I made the War and deployed it in Tomcat5.5 when i run it tin browser, it gives the following error:
