Hello again,

I wrote struts-config.xml wrong, the rright one is as follows:

  <!-- -->
  <action path="/showx"
      attribute="XForm"
      scope="request"
      validate="false"
      type="com.xxx.yyy.ShowXAction">
    <forward name="success" path="/x.jsp"/>
  </action>
  <!-- -->
  <action path="/x"
      name="XForm"
      scope="request"
      input="/showx.do"
      validate="true"
      type="com.xxx.yyy.XAction">
    <forward name="success" path="/showy.do"/>
  </action>
cheers,
tuna

Hello,

I lose all form data  if validate returns error for the form input. If
   

 

action goes through validation without creating of any errors, XAction
   

 

works fine. ShowXAction is used to display jsp and jsp posts to 
XAction. Any comments?
You can see the code below.

cheers,

*************************

ShowXAction.java looks like follows:

public final class ShowXAction extends Action {

  public ActionForward execute(ActionMapping mapping, ActionForm
   

form,
 

          HttpServletRequest request, HttpServletResponse response)
          throws Exception{
      // Update form data
      if (form == null) {
          form = new XForm();
          if ("request".equals(mapping.getScope()))
              request.setAttribute(mapping.getAttribute(), form);
          else
              session.setAttribute(mapping.getAttribute(), form);
      }
            XForm f = (XForm)form;
            f.setA("...");
      f.setB("...");
          //ensure, that form is submited only once
      saveToken(request);                            return 
mapping.findForward("success");

  }

XAction.java looks like:

public final class XAction extends Action {

  public ActionForward execute(ActionMapping mapping, ActionForm
   

form,
 

          HttpServletRequest request, HttpServletResponse response)
          throws Exception {
                   XForm f = (XForm)form;
      XBean b = new XBean(f.getA(), f.getB());
      b.store();
        //ensure, that form is submited only once
      saveToken(request);                            return 
mapping.findForward("success");
}

and struts-config.xml is like follows:

  <!-- -->
  <action path="/showx"
      attribute="XForm"
      scope="request"
      validate="false"
      type="com.xxx.yyy.ShowXAction">
    <forward name="success" path="/x.jsp"/>
  </action>
  <!-- -->
  <action path="/x"
      name="XForm"
      scope="request"
      input="/x.do"
      validate="true"
      type="com.xxx.yyy.XAction">
    <forward name="success" path="/showy.do"/>
  </action>
and finally XForm is like follows:

public final class XForm extends ActionForm {

  private String a = null;
    private String b = null;
    public String getA() {
      return this.a;
  }
  public void setA(String a) {
      this.a = a;
  }
    public String getB() {
      return this.b;
  }
    public void setB(String b) {
      this.b = b;
  }
    public void reset(ActionMapping mapping, HttpServletRequest
request) {
            this.a = null;
      this.b = null;
  }

  public ActionErrors validate(ActionMapping mapping,
                               HttpServletRequest request) {
      ActionErrors errors = new ActionErrors();
            if ((this.a == null) || (this.a.trim().length() == 0)) {
          errors.add(ActionErrors.GLOBAL_ERROR, new
ActionError("form.a.missing"));
      }
            if ((this.b == null) || (this.b.trim().length() == 0)) {
          errors.add(ActionErrors.GLOBAL_ERROR, new 
ActionError("form.b.missing"));
      }
      return errors;
        }

  public String toString() {
      StringBuffer sb = new StringBuffer("XForm[");
      sb.append("a=").append(this.a);
      sb.append(",b=").append(this.b);
      return sb.toString();
  }
}
