Java.lang.NoSuchMethodError with JDeveloepr 10g

Question

HI,
I have a problem with java.lang.NoSuchMethodError in Jdeveloper 10g. The code works fine in Jdeveloper 9iAS. I just migrated them to 10g.
Here is the error:
java.lang.NoSuchMethodError: java.util.ArrayList com.ncilp.intranet.CourseHelperBean.getAllCoursesByPosition(int, int)     at com.ncilp.intranet.SelectCourseForm.getCourseSelection(SelectCourseForm.java:72)     at com.ncilp.intranet.SelectCourseForm.reset(SelectCourseForm.java:55)     at org.apache.struts.taglib.html.FormTag.doStartTag(FormTag.java:640)     at selectcourse.jspService(_selectcourse.java:74)     [selectcourse.jsp]     at com.orionserver[Oracle Containers for J2EE 10g (10.1.3.0.0) ].http.OrionHttpJspPage.service(OrionHttpJspPage.java:60)     at oracle.jsp.runtimev2.JspPageTable.service(JspPageTable.java:416)     at oracle.jsp.runtimev2.JspServlet.internalService(JspServlet.java:478)     at oracle.jsp.runtimev2.JspServlet.service(JspServlet.java:401)     at javax.servlet.http.HttpServlet.service(HttpServlet.java:856)     at com.evermind[Oracle Containers for J2EE 10g (10.1.3.0.0) ].server.http.ServletRequestDispatcher.invoke(ServletRequestDispatcher.java:719)     at com.evermind[Oracle Containers for J2EE 10g (10.1.3.0.0) ].server.http.ServletRequestDispatcher.forwardInternal(ServletRequestDispatcher.java:376)     at com.evermind[Oracle Containers for J2EE 10g (10.1.3.0.0) ].server.http.HttpRequestHandler.doProcessRequest(HttpRequestHandler.java:870)     at com.evermind[Oracle Containers for J2EE 10g (10.1.3.0.0) ].server.http.HttpRequestHandler.processRequest(HttpRequestHandler.java:451)     at com.evermind[Oracle Containers for J2EE 10g (10.1.3.0.0) ].server.http.HttpRequestHandler.serveOneRequest(HttpRequestHandler.java:218)     at com.evermind[Oracle Containers for J2EE 10g (10.1.3.0.0) ].server.http.HttpRequestHandler.run(HttpRequestHandler.java:119)     at com.evermind[Oracle Containers for J2EE 10g (10.1.3.0.0) ].server.http.HttpRequestHandler.run(HttpRequestHandler.java:112)     at oracle.oc4j.network.ServerSocketReadHandler$SafeRunnable.run(ServerSocketReadHandler.java:260)     at com.evermind[Oracle Containers for J2EE 10g (10.1.3.0.0) ].util.ReleasableResourcePooledExecutor$MyWorker.run(ReleasableResourcePooledExecutor.java:303)     at java.lang.Thread.run(Thread.java:595)

These two classes are in the same directory, same package. Can anyone tell me what's wrong? How to fix it?
Thank you very much.
