argument type mismatch at org.apache.commons.beanutils.PropertyUtilsBean.invokeMethod

I was getting the following error when ever I submit the form..

java.lang.IllegalArgumentException:

Cannot invoke mismatch at org.apache.commons.beanutils.PropertyUtilsBean.invokeMethod(PropertyUtilsBean.java:1778) at org.apache.commons.beanutils.PropertyUtilsBean.setSimpleProperty(PropertyUtilsBean.java:1759) at org.apache.commons.beanutils.PropertyUtilsBean.setNestedProperty(PropertyUtilsBean.java:1648) at org.apache.commons.beanutils.PropertyUtilsBean.setProperty(PropertyUtilsBean.java:1677) at org.apache.commons.beanutils.BeanUtilsBean.setProperty(BeanUtilsBean.java:1022) at org.apache.commons.beanutils.BeanUtilsBean.populate(BeanUtilsBean.java:811) at org.apache.commons.beanutils.BeanUtils.populate(BeanUtils.java:298) at org.apache.struts.util.RequestUtils.populate(RequestUtils.java:493) at org.apache.struts.action.RequestProcessor.processPopulate(RequestProcessor.java:805) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:203) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1194) at org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:432) at javax.servlet.http.HttpServlet.service(HttpServlet.java:763) at javax.servlet.http.HttpServlet.service(HttpServlet.java:856) at weblogic.servlet.internal.StubSecurityHelper$ServletServiceAction.run(StubSecurityHelper.java:223) at weblogic.servlet.internal.StubSecurityHelper.invokeServlet(StubSecurityHelper.java:125) at weblogic.servlet.internal.ServletStubImpl.execute(ServletStubImpl.java:283) at weblogic.servlet.internal.ServletStubImpl.execute(ServletStubImpl.java:175) at weblogic.servlet.internal.WebAppServletContext$ServletInvocationAction.run(WebAppServletContext.java:3245) at weblogic.security.acl.internal.AuthenticatedSubject.doAs(AuthenticatedSubject.java:321) at weblogic.security.service.SecurityManager.runAs(SecurityManager.java:121) at weblogic.servlet.internal.WebAppServletContext.securedExecute(WebAppServletContext.java:2003) at weblogic.servlet.internal.WebAppServletContext.execute(WebAppServletContext.java:1909) at weblogic.servlet.internal.ServletRequestImpl.run(ServletRequestImpl.java:1359) at weblogic.work.ExecuteThread.execute(ExecuteThread.java:209) at weblogic.work.ExecuteThread.run(ExecuteThread.java:181)

took me a looong time to realize that I was setting the value to a worng variable.. which would obviously cause type mismatch and thus IllegalArgumentException....

Be sure to chk ur form variables in the jsp and values are being set to right variables when the form is submitted. :)) In my case the error was at



Happy Coding :))
