Failure to compile as a java class in Struts

2003-12-10 09:58

Hi,

 

I've read all the samples and documentation and think I must be a bit thick but I am having trouble getting my ReportManager class to compile reports.

 

The error I am getting is :

I simply just don't understand why I should get this problem as the jasper jar is in the WEB-INFlib directory of the webapp as well as being in the lib directory of the server in JBOSS.

 

The code I am using is :

 

String pathToFile = getFilePath(reportName);

 

System.setProperty("jasper.reports.compile.temp", ApplicationProperties.getProperty("compiledReportDir"));

JasperCompileManager.compileReportToFile(pathToFile);

 

The path to the file is on my local drive as this is similar to how the report xml files are loaded within the production system.

 

The idea is to allow users to be able to upload, compile and publish reports to other users based on user privileges. This will be run from within a workflow application built on struts. Therefore I need a java class that can have a struts action wrapper.

 

Any clues as to my problem will be much appreciated

I have the same problem when I try to compile reports in a struts app deployed on Weblogic Server v6.1

Hi,

 

Be sure to also set the classpath for the compilation:

 

System.setProperty("jasper.reports.compile.class.path", reportClasspath);

I've tried adding the classpath using an absolute reference but this doesn't seem to make any difference.

 

Does it have anything to do with application context? I've noticed that both the relevant examples I've looked at (the Servlet and the JSP) both run the compile from within an application context whereas I will be compiling reports located in an external (to the Server) directory.

Hi Jo,

 

I have been using an absolute reference. Here is the entry from my properties file:

 

jasper.reports.compile.class.path=Q:SIMPLETRADE2libjasperreports-0.5.0.jar

Thanks Guys for all your help, typically it was a stupid mistake that was causing my problem, I wasn't referencing the jar file correctly, I was only pointing to its directory rather than the file itself
