NoClassDefFoundError for class in jar in project

[icccapital]

I am trying to test a report that uses java beans for its data source.  The createBeanCollection method uses MyBatis to fill the java beans and returns a list of the beans.  The application runs fine filling the beans and returning the list of beans from createBeanCollection when I test it.  But when I try to preview the report in IReport i get the error below.  When I compile the report I can run it in the application and everything works fine.  I am trying to edit the look of the report with live data, but can't easily because of this issue.  the org/apache/ibatis/io/Resources class is in the mybatis jar, which is in the dist/lib of the project.
