java.lang.NoClassDefFoundError: org/apache/commons

[timmyd]

The basics:

OS: Fedora Core 5

JDK: 1.4.2

IDE: IntelliJ 5.1.2

iReport: 1.2.5

Jasper: 1.2.5

DB: Oracle 8i

 

The problem:

I create a report (nothing fancy) in iReport and generate a .jrxml file. In iReport I can compile/view this using all types of viewers (pdf, html, JRViewer, etc.).

 

When I create a java class (packaged as a jar) to do the load-compile-fill-view process, it pukes this mysterious error:

 

Code:

This happens during the 'fill report' stage, after a successful db connection has been established.

 

Here's the steps:

Code:

[code] JasperDesign design = JRXmlLoader.load (repFile); JasperReport report = JasperCompileManager.compileReport (design); Connection conn = getConnection (dbUrl, dbUser, dbPass); JasperPrint print = JasperFillManager.fillReport (report, new HashMap (), conn); JasperViewer.viewReport (print);

 

I'm lost. Any ideas?

I found it.

 

The library: commons-javaflow-20060411.jar is required.

 

This is included in iReport, which is why the problem didn't crop up when I generated and viewed these reports from there.

Issue:

 

I am seeing the same class not found issue and am working with JR 1.3.0 . I do have jasperreports-1.3.0-javaflow.jar in my libs and still get this error. I just downloaded from SourceForge all files for 1.3.0 including jasperreports-1.3.0-project.tar.gz . Looking inside jasperreports-1.3.0-javaflow.jar, I see nothing for org/apache/commons/javaflow/bytecode/...

 

Solution:

 

Inside jasperreports-1.3.0-project.tar.gz I found commons-javaflow-20060411.jar which I included into my libs and now I am past this issue. I would have thought this lib would be inside jasperreports-1.3.0-javaflow.jar .
