One possible cause of the problem of a blank page being returned in a Struts application is that of returning a null forward from the execute() method of an action class. Check to see that you have a statement similar to this:

return mapping.findForward("xyz");

at the end of your execute() method. Then check to see that the "xyz" represents a valid global forward, or a local forward for this action as defined in your struts-config.xml file.

Thank you for your suggetion. It is a local forward and looks like this.

public final class InsertEmployeeAction extends Action {

public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
System.out.println("Here ..11");
EmployeeService service = new EmployeeService();
EmployeeForm employeeForm = (EmployeeForm) form;
EmployeeDTO employeeDTO = new EmployeeDTO();
BeanUtils.copyProperties( employeeDTO, employeeForm );
service.insertEmployee( employeeDTO );
request.setAttribute("employee",employeeDTO);
return (mapping.findForward("success"));
}
}

///struts-config.xml

<struts-config>
<!-- Form Bean Definitions -->
<form-beans>
<form-bean name="employeeForm" type="net.reumann.EmployeeForm"/>
</form-beans>
<!-- Action Mapping Definitions -->
<action-mappings>
<action path="/setupEmployeeForm" forward="/employeeForm.jsp"/>

<action path="/insertEmployee"
type="net.reumann.InsertEmployeeAction"
name="employeeForm"
scope="request"
validate="false"
>
<forward
name="success"
path="/confirmation.jsp"/>
</action>
</action-mappings>
<!-- message resources -->
<message-resources
parameter="ApplicationResources"
null="false" />
</struts-config>

Here are some more things to check:

  • use the browser's "view source" function to look at the blank page. Sometimes a page is being produced, but it has malformed html, and doesn't display.
  • Verify that action="insertEmployee" is specified on your <html:form> tag.

  • Put System.out.println() statements in your execute() method to verify that it is actually getting called.
  • change the way you're getting the forward so you can see whether it's successful or not, as in this example
