Question in developing JSP with Struts

Hello,everybody.
Recently,I wrote a simple JSP Web program basing on the Struts architecture.It created a page for a user to input his name and password,and after the user click the submit botton on the form,it can redirect to another page and show the name and password that the use has input on the page.I have completed the program but it can't work properly.
I listed each part of the program as following:
(a) TestForm.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<head>
<title>Login Interface</title>
</head>
<body vLink="#006666" link="#003366" bgColor="#E0F0F8">
<img height="33" src="image/enter.gif" width="148">
<form action="ReadTestForm.do" method="post">
UserName:
<input size="15"name="PersonName"><p>
Password:
<input type="password" size="15" name="Psw"><p>
<input type="submit" value="Submit">
</form>
(b) MTestForm.java
package Test;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionMessage;
public class MTestForm extends ActionForm{
     private String PersonName = null;
     private String Psw = null;
     public MTestForm(){}
public void setPersonName(String name) {
          this.PersonName = name;
     public String getPersonName() {
          return PersonName;
     public void setPsw(String psw) {
          this.Psw = psw;
     public String getPsw() {
          return Psw;
     public void reset(ActionMapping mapping,
          HttpServletRequest request) {
          this.PersonName = null;
          this.Psw = null;
(c) ReadTestFormAction.java
package Test;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionMessages;

import javax.servlet.ServletContext;

import javax.servlet.http.*;
public final class ReadTestFormAction extends Action{
     public ActionForward execute(
               ActionMapping mapping,
               ActionForm form,
               HttpServletRequest request,
               HttpServletResponse response) throws Exception {
               MTestForm TestFormBean = (MTestForm) form;
     String PersonName = TestFormBean.getPersonName();
     String Psw = TestFormBean.getPsw();
     return mapping.findForward("ReadTestFormOk");
(d) ShowForm.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"

</struts-config>
After I accessed the page of "TestForm.jsp" and input the " Username and Password",click "Submit " button ,it can redirect to the page of "ShowForm.jsp",but each time both the Username and Password are "Null", It meaned that the statement {which is MTestForm ReadformBean1 = (MTestForm)request.getAttribute("TestFormBean1");
} and its following statement in the "ShowForm.jsp" can't accessed what the user have input for the Textboxs of Username and Password.
I have tried and tried and modify the program for many times,but it have not been solved.
Can you help me to check out what is the wrong with the program?
Thanks you for help and Regards
(Can you anybody tell me how edit the text so that it can been printed out clearly in this forum?)

Well as far as i see there is no mapping working between
Form input and ActionForm Bean properties as the reset() method would be called b4 action class
you need to map the properties in the below fashoin

JDeveloper editing JSP with Struts tags terribly, terribly slow!?

I use JDeveloper 10.1.2 and I do not know the reason but it started to take 15min just to change/edit JSP containing Struts tags. RAM memory is 1GB and there is more than 0.5 GB available, but processor usage shows 100% allocated to JDeveloper!? As soon as I do even slight change in a JSP file JDeveloper starts some computations and I have no idea of what it is doing.
What is JDeveloper computing? It seems it tries to produce some drop-down lists "helping" me to do the editing, add tags and instead I am spending days to just change one small JSP page!
How can I stop and PREVENT JDeveloper doing ANY "help" during editing of ANY file?
There must be an option to switch off whatever JDeveloper is doing?
Many thanks,

I did that but it is still very slow, it looks like Jdev is doing some intensive calculations whenever I click somewhere on JSP page with tags. Maybe this is related with my other question I posted before this one? Maybe JDev automatically searches for tag libraries it cannot find and copies them to /WEB-INF directory? (other IDEs used in same environment, like Eclipse and IntelliJ, and they do not have this problem)
Some other strange things: struts-config.xml seems not integrated with CVS from JDev (other files like tiles-config.xml, web.xml etc. are integrated, I can right click and get CVS info on particular file, except struts-config.xml). When I want to check in/out struts-config.xml I have to do it with external tool like WinCVS etc., cannot do that from JDev!

Show jsp with struts

hello,
i'm building a web-application with struts. now i have the following problem (i don't find den reason, although i'm trying for hours):
i want to show in the browser (with tomcat) a jsp-site. this site consists of different jsp-parts:
file neujob.jsp
<%@ taglib uri='/WEB-INF/struts-template.tld' prefix='template' %>
<template:insert template='/templates/eshop.jsp'>
<template:put name='header' content='/templates/header.jsp' />
<template:put name='view' content='/view/erstellen.jsp' />
<template:put name='footer' content='/templates/footer.jsp' />
</template:insert>
header and footer are shown correctly, when i call http://localhost:8080/pmtool/neujob.jsp in the browser; but the view-part is not shown. independent of how it looks. even this narrow-version doesn't work:
file erstellen.jsp
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
huhu<br>
huhu<br>
the login.jsp-site however is shown correctly, and actually it is built similarly.
what may be the reason? what gets wrong?
thank you for your help!

sorry! now i've found my mistake!

Trying to submit back to jsp with struts

Ok, so I have a jsp page that displays tons of stuff.
I get there from the struts flow of:
InputFormJsp -> strutsFormBean ->strutsActionBean->JSP View Page
So I'm at my view page and I was to resubmit back to the view page again using a bunch of hidden input fields to redo the page with different vars (historic data, based on the 1st time through).
So it will go:
JSP View Page->strutsFormBean->strutsActionBean->JSP View Page
I want to use the same form and action beans and the same view page, just want to pass the hidden vars instead of prompting the user all over again.
I have my form and hidden fields set up, but my problem is how do I get struts to see the resubmit. I made a new actionmapping that labeled the "input" as the same jsp page as the forward but I keep getting:
javax.servlet.ServletException
     org.apache.struts.action.RequestProcessor.processException(RequestProcessor.java:523)
     org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:421)

     javax.servlet.http.HttpServlet.service(HttpServlet.java:709)
     javax.servlet.http.HttpServlet.service(HttpServlet.java:802)followed by a good old NullPointerException from my actionbean's execute method (I think):

     javax.servlet.http.HttpServlet.service(HttpServlet.java:709)
     javax.servlet.http.HttpServlet.service(HttpServlet.java:802)struts-config.xml looks like:
<action   path="/getSysReport"
              type="com.air2web.SysReportAction"
              name="SysReportForm"
              input="/pages/SysReport.jsp"
              scope="request">
    <forward name="success" path="/pages/genSysReport.jsp"/>
    </action>
<action   path="/getSysReportHistoric"
              type="com.air2web.SysReportAction"
              name="SysReportForm"
              input="/pages/genSysReport.jsp"
              scope="request">
    <forward name="success" path="/pages/genSysReport.jsp"/>
    </action>Is there a way to specify many input pages or some other trick to do this??
Thanks
Chris Liles

I had exactly the same problem with Struts, and Finally I solve this.
first of all put into <form-beans> the form path
    <form-bean name="updUserForm" type="com.yourcompany.struts.form.UpdUserForm" />and in <action-mappings >
    <action
      attribute="updUserForm"
      input="/UpdateUser.jsp"
      name="updUserForm"
      path="/updUser"
      scope="request"
      type="com.yourcompany.struts.action.UpdUserAction" >
      <forward name="success" path="/MyJsp.jsp" />
    </action>Be carefull with the first letter of attribute and name they must be in minus! (Instead of mayus in form).

Problem compling JSP with struts tags on Weblogic 8.1

File save JSP with struts

I have a web application which saves the data from DB query in csv format.
I am having problem with saving the file.
I get the correct result and i can alos save the file.
Where i am having problem is after the file is saved i want my page to go to
another page which shows the data of the file.
What i did was in my struts config file i gave the path of the jsp that shows
the data, but after the file is saved my page is not redirected.
so what i did was i first redirected to another page, and used javascript
onload function and gave the path of the action that saves the file.
However, even when the page is redirected instead of saving the data
it saves the html source of the jsp. i dont know why this is happenig.
anybody with any idea on how can i redirect to another page after saving
the file or redirecting to another page and saving the file, with correct data?
please help

Post snippets from your struts-config.xml and code. This will give idea to ppl who are trying to help.

Help: OJSPC can not compile the JSP with struts tag

Hi,
I am trying to precompile the JSP page with EAR package but OJSPC can not parse the Struts tags.
I always get oracle.jsp.parse.JspParseException:
Error: org.apache.struts.taglib.html.MessgesTei while reading TLD /WEB-INF/tld/struts-html.tld
My OC4J version is 10.1.3.2 and I did tried putting the struts-taglib.jar to /opt/oracle/product/app10g/j2ee/home/jsp/lib or /lib/taglib
but still do not work.
Can anyone tell me how to configure the OJSPC and let it support customerized taglibs?
Thanks a lot!

This is a new problem with jdk1.4 when compiling with tomcat.
The solution is to ensure that any classes in WEB-INF/classes are in a package structure and the relevant jsp calls the same using the package name.

It looks like Jrun doesn't understand valid TLDs .It seems that we must use its own jruntags.jar files.I means we could add our .class and .tld to the jruntags.jar.

WLS 8.1 sp1 with Struts 1.1 JSP with bean tag won't compile

          Hello,
          We are currently porting our application which uses struts 1.1 to WLS 8.1 sp1
          from another app server. Everything seems to deploy correctly and pages which
          use struts tags appear to compile and run fine. However, the pages with struts
          <bean:define> tags are not compiling.
          Example JSP Code:
          <bean:define id="userForm" name="userForm" scope="session" toScope="page" type="UserFormBean"/>
          <% if (userForm.hasUserData()) {hasUser=true;} %>
          WLS Console Output:
          ..jsp_servlet\_jsp\_sailor\__home.java:493: cannot resolve symbol
          symbol : variable userForm
          location: class jsp_servlet._jsp._sailor.__home
          if (userForm.hasUserData()) { //[ /jsp/sailor/home.jsp; Line: 38]
          When I look at the JSP's parsed java code (__home.java:493) I find that nowhere
          in the class is the variable userForm declared.
          Is this a bug in WLS? Does anyone know of a workaround?
          Thanks,
          Scott

Need a help with Struts Tiles dynamic menu

Hello,
I am started few days ago with Tiles, try to develop web application.
Can anybody sugest very simple example with Tiles and menu.
So my definition looks like this:
tiles-def.xml
<tiles-definitions>
<definition name="MainDefinition" path="/layouts/myLayout.jsp">
<put name="title" value="This is the title." />
<put name="header" value="/tiles/header.jsp" />
<put name="menu" value="/tiles/menu.jsp" />
<put name="body" value="/tiles/body.jsp" />
<put name="footer" value="This is the footer." />
</definition>
I am simple layout.
I need to on menu click change body content, now i am doing it like this:
index.jsp
<%@ page language="java" %>
<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%String body = request.getParameter("body");%>
<tiles:insert definition="MainDefinition" flush="true">
<tiles:put name="body" type="string"> <%= body %> </tiles:put>
</tiles:insert>
But now body is a string how to make it open url?
Maybe somebody have link to menu Tiles good examples.
Thanks

But here's some useful advice :P
I'm going to assume that the other two people involved in this have a bit more experience, have them do most of the designing. Have them leave most of the easy stuff for you. You can then spend your time learning the minimum of what you need to know. And if you have problems, or don't understand things, ask your partners for help.
And you'll want to set some spare time for you to all get together and do something fun so that you don't kill each other because of the stress :P
I've had a lot of bad project experiences, fortunatly they where all just at school :P I blame myself, mainly because I didn't do the whole thing myself (mostly because I listened to people when they said that I shouldn't or couldn't do everything myself.) I'd like to say that it's mostly because of poor communication, and disorganization, but an awful lot of it had to do with the fact that I tend to be the only person with any work ethic what so ever.
But whinning and repressed memories aside, good communication and organization help a lot. Come up with a good system with your team mates. And don't be afraid to ask questions. And don't worry about dividing up the work load equally. Just make sure you put in a good amount of effort, if not frightening amounts.
If all of you are clueless, divide up the learning stuff between yourselves too.
I have no experience with Struts. I've done a bit of stuff with XML, but nothing too complicated. The XML by itself tends to be extremely easy. What you plan on doing with it can vary (I don't like XML incidentally :P)
Other then that, good luck.

Error 500, deployment with struts

An application developed in JDeveloper 9.02 with struts 1.1b works fine when running using the local OC4J instance running from JDeveloper. I created a deployment profile with a .war and .ear, deployed to the OC4J standalone instance using the EM website, and all seemed well. Now it sporadically gives the "Internal Server Error" when navigating between pages. I can't find anything in the logs, and ideas?

It's OC4J core install for 9iAS Release 9.02. I've deployed to Solaris since there is a bug that can give this error that is patched for Solaris, but not Windows. The error occurs when navigating pages in a struts app. Sometimes it works fine, then you click on one of the image buttons to go to the next .jsp and this error comes up.
Ruth
What version of OC4J you are testing on ?
Is it OC4J standalone or Oracle9iAS that you are using.
more details would be helpful in diagnosing the problem.
