Cannot figure out why Formbean is null in this code...

[Sean Gildea]

I cannot figure out why my formbean is null. Can someone please take a look at my code and possibly shed some light on what I may be doing wrong?

When I run this, the blogBean object is null with a NPE.

Thanks in advance,
Sean Gildea

 package coreservlets;

import org.apache.struts.action.*;
 
public class BlogAction extends Action {
  public ActionForward execute(ActionMapping mapping,
                               ActionForm form,
                               HttpServletRequest request,
                               HttpServletResponse response)
      throws Exception {
      
  BlogFormBean blogBean = (BlogFormBean)form;
    
    String title = blogBean.getTitle();
    String entry = blogBean.getEntry();
       
    request.setAttribute("blogBean", blogBean);
    
    if ((title == null) || (title.trim().length() < 1)) {
      return(mapping.findForward("no-entry"));
    } else if ((entry == null) || (entry.trim().length() < 1)) {
      return(mapping.findForward("no-entry"));
    }
    
return(mapping.findForward("blog-success"));
  }
}

What does your ActionMapping look like in the struts-config? Did you specify the name attribute to say which ActionForm it uses?

Hi Marc,

I made a mistake in the struts-config.xml, that fixed it, thanks!

 <form-beans>
    <form-bean name="blogFormBean"
               type="blogdb.BlogFormBean"/>
  </form-beans>
 
  <action-mappings>
    <action path="/processblog" 
            type="blogdb.BlogAction"
            name="blogFormBean"
            scope="request">
      <forward name="no-entry" 
               path="/WEB-INF/results/no-entry.jsp"/>
      <forward name="blog-success" 
               path="/WEB-INF/results/blog-success.jsp"/>
    </action> 
  </action-mappings>
