Jasper Reports, generating temporary file --> test.java

I’m trying to incorporate Jasper Reports with my current project, and I’m having some trouble using Spring’s Web MVC.

Here’s what I’ve done so far:

First I created my “test.jrxml” file using iReports. Copied this file into my “webapp/WEB-INF/” directory. I’ve created a class called “JasperReportsController” which extends “JasperReportsMultiFormatView”. I’m using Eclipse with a Tomcat plugin (4.1.x). I’ve followed the example from springs documentation, section 13.7.3. It seems that whenever I run Tomcat Server, that the “test.java”, temp file, is generated immediately. For some strange reason “test.java” is generated inside the following directory “C:\webarch\eclipse\test.java”, as opposed to my projects location “C:\webarch\projects\%my_project_name%”. This is causing there to be classpath issues, because it can’t seem to see any of the jasper reports library classes. The following is a console snippet of the error:

C:\webarch\eclipse\test.java:4: package net.sf.jasperreports.engine does not exist
import net.sf.jasperreports.engine.*;

C:\webarch\eclipse\test.java:5: package net.sf.jasperreports.engine.fill does not exist

Are there any suggestions on how I can make this temporary file get generated at least within the projects directory?

Your controller shouldn't extends JasperReportsMultiFormatView - check out the sample app which can be obtained from CVS. You should also make sure that only version of JasperReports is on the classpath.

Rob thanks for replying. The example actually helped me out with some other issues. But I found out the reason why this file was being generated in the wrong directory. There's a file that the jasper reports library looks for called "jasperreports.properties". There was no documenation on this but you can set a couple of properties here, like the classpath of your referenced libraries and the location of where you wanted temp file to be generated.

#jasper reports properties
net.sf.jasperreports.compiler.temp.dir=....
net.sf.jasperreports.compiler.classpath=....
