Hi,

I am getting the same error when I try to run my java program that is accessing jasper report created using IReport. I have put the following .jar files to my classpath.
1.jasperreports-1.2.0.jar
2. classes12.jar (for Oracle JDBC connection)
3. commons-beanutils-1.5.jar
4. commons-collections-2.1.jar
5. commons-digester-1.7.jar
6. commons-logging-1.0.2.jar

But still I am getting this error:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/ja
vaflow/bytecode/Continuable

at ReportDriver.runReport(ReportDriver.java:69)
at ReportDriver.main(ReportDriver.java:88)

Can you guys please let me know what other .jar files I need to copy/set to my classpath???

Thanks,
Rama

As the error message (kind of) states, it's the Jakarta Commons Javaflow package that's missing. No binary distribution seems to be available for that, according to that page, so you may need to pull the sources out of SVN and compile and jar it yourself. It may also be included in the full JasperReports download.

It is sorta covered in the JavaRanch Style Guide.
