I'm trying to access a static constant from a JSP page in Struts 2.0.14, but
it is not working.

My JSP page:

<s:select list="@org.my.company.myClass@(protected)" />

Java code:

package org.my.company;

import java.util.ArrayList;
import java.util.List;

public Class myClass {

public static final List<String> AVAILABLE_STATES = getStates();

public static final List<String> getStates() {
List<String> states = new ArrayList<String>();
states.add("New York");
return states;
}

When I try to access my jsp page, I receive the following error message:

Caused by: tag 'select', field 'list': The requested list key
'@org.my.company.myClass@(protected)
collection/array/map/enumeration/iterator type. Example: people or
people.{name} - [unknown location]

Does anyone have any suggestion about what needs to be changed?

Thanks!

I figured it out.

In myClass, I have an enum listing the different state values. My
AVAILABLE_STATES variable was placed inside the curly braces for the enum.
This inadvertently placed the AVAILABLE_STATES variable inside the enum and
caused Struts 2 to throw an error message.

Hi,

Am building an application in struts2 and tiles. My requirement is to
retrieve an image blob from mysql database and display the image in a jsp
using img tag as below..

img src="<s:url action="myAction"/>"

Part of my struts.xml is as below:

<package name="default" extends="struts-default">
    <result-types>
       <result-type name="tiles"
class="org.apache.struts2.views.tiles.TilesResult" />
       <result-type name="myBytesResult"
class="com.icensa.action.MyBytesResult" ></result-type><br>
    </result-types>
     <action name="myAction" class="com.icensa.action.MyAction">
         <result name="myImageResult" type="myBytesResult" />
     </action>
</package>
My MyBytesResult class is:

public class MyBytesResult implements Result {

 private static final long serialVersionUID = 1L;
 

 public void execute(ActionInvocation invocation) throws Exception {
   
   MyAction action = (MyAction) invocation.getAction();
   HttpServletResponse response = ServletActionContext.getResponse();

    response.setContentType("image/jpeg");
   //response.setContentLength(action.getMyContentLength());

   response.getOutputStream().write(action.getMyImageInBytes());
   response.getOutputStream().flush();
 }

}

And MyAction class is:

public class MyAction extends ActionSupport {
 
 private static final long serialVersionUID = 1L;
 Blob image = null;
  Connection con = null;
  Statement stmt = null;
  ResultSet rs = null;
  byte[] imgData = null;
  OutputStream o = null;
  HttpServletResponse response = ServletActionContext.getResponse();
 public String doDefault() {
   System.out.println("doDefault()");
   try {
       Class.forName("com.mysql.jdbc.Driver");
       con =
DriverManager.getConnection("jdbc:mysql://localhost:3306/project","root","pass");
       stmt = con.createStatement();
       rs = stmt.executeQuery("select * from books_tb where
category='General' order by publish_date desc");
       while (rs.next()) {
          image = rs.getBlob(11);
          imgData = image.getBytes(1,(int)image.length());          
      }
     }
   catch (Exception e) {
          System.out.println(e.getMessage());        
      }
    return "myImageResult";
  }

  public byte[] getMyImageInBytes() {
    System.out.println("getMyImageInBytes()");
    try{
   
    }
    catch (Exception e) {
        System.out.println(e.getMessage());
       
    }
    return imgData;
  }

 // public String getMyContentType() { }
 // public String getMyContentDisposition() {}
 // public int getMyContentLength() { }
 // public int getMyBufferSize() { }

 }

when i run the code the image is not displayed and I get an error saying
No result defined for action com.action.MyAction and result success

In struts.xml is I provide reslut name="success" and the jsp, it does not
throw an error but not displaying the image. However in any case it is not
going to MyAction.java. What could i do to rectify this?
Could provide you with required code if necessary..

Thanks,
Aruna

Being a fan of the KISS policy... I played around with
this but didn't have the time to figure it out, so I
made the URL spat out by struts2 points to a servlet
instead of struts2.

(Note that my web.xml has struts2 configured to listen
for *.action rather then slash-star)

Good luck & please let me know what your solution is.

Thanks!

Hi,

  I have a plain vanilla servlet and I want to "include" via the
RequestDispatcher mechanism the rendered output of a struts page. Here's
the code I have:

  ServletContext ctx = servletConfig.getServletContext();
    RequestDispatcher rd =
ctx.getRequestDispatcher("/modules/foo/Home.do?myparam=value");
    if (rd != null) {

      StringWriter stringWriter = new StringWriter();
      MyResponse myresponse = new MyResponse(response, stringWriter);
      rd.include(request, myresponse);
      System.err.println(stringWriter.toString());

    }

I created MyResponse as a wrapper on ServletResponse that contains a
buffer so I can pull out the contents. However, I'm not getting anything....

Has anyone done this before? Or is there some easy way to do this?

Thanks, Jason

IOW, the old famous and, sigh, obsolete framework for web application.

> 2 = Struts 2

IOW, the framework that has been imported from the OpenSymphony's
WebWork framework codebase.

As you can see, they are not two versions of the same framework, but
two different products, connected only by their name.

Yes, you could extract the 2nd webapp response's body and insert it
into the 1st. For this, take a look at Sitemesh:
http://www.opensymphony.com/sitemesh/

> Is it possible to use Struts Tiles for this ?

You can use Tiles and Frames together, you should use the normal HTML
tags for frames and insert attributes using Tiles JSP tags. Notice
that Tiles may work only under a single webapp, currently it cannot
extract content from an external resource.
For questions about Tiles, please ask the Tiles Users mailing list:
http://tiles.apache.org/mail.html

Hi,

We have an action which causes an Infinite recursion detection. I
don't have any idea why this is happening. When we call the action the
first time everything is ok. But when we call this the second time we

I have no clue. No chained actions nothing. When I trigger the action
the second time, the action is not reached anymore.
I have never seen anything like this before.

I guess it has something to do with the form data.

Anyone any idea?

Hi people,

i'm a newbie to struts2. I'm having too many problems modifing session
parameters. I use <%= session.getAttribute( "variable" ) %> to gain
access to "variable" and that works when i modify "variable" into a jsp
page, but not inside a struts action.

struts.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
 "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
 "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>

 <constant name="struts.enable.DynamicMethodInvocation" value="false" />
 <constant name="struts.devMode" value="true" />

<package name="tads" namespace="/" extends="struts-default">

<action name="HolaMundo" class="tads.HolaMundo">
<result>/holaMundo.jsp</result>
</action>

<action name="Catalogo" class="tads.Catalogo">
  <result name="error">/ErrorCatalogo.jsp</result>
  <result>/Catalogo.jsp</result>
 </action>

<action name="Actualiza" class="tads.Actualiza">
  <result>/Actualiza.jsp</result>
 </action>



</package>

</struts>

extract from a jsp page, result from an ajax action working:

<s:form id="form" >
          <s:textfield name="politico" label="politico"/><br>  
          <s:hidden name="prueba" value="escondido" />
         </s:form>
         <s:url id="actualiza" value="/Actualiza.action" />

<sx:submit type="button" label="dale" href="%{actualiza}" formId="form"
align="center" targets="secondaryContent"/>

i see "politico" and "prueba" into Actualiza.action so the action
Actualiza works.

Actualiza.java:

package tads;
import java.util.*;

import javax.servlet.http.HttpSession;
import com.opensymphony.xwork2.ActionSupport;
import org.apache.struts2.interceptor.SessionAware;
import com.opensymphony.xwork2.ActionContext;


@SuppressWarnings("serial")
public class Actualiza extends ActionSupport implements SessionAware {
 private String politico;
 private String prueba;
 private Map session;
  public String execute() throws Exception {

    this.getSession().put("variable","pruebamil");
    return SUCCESS;
    }
 public String getPolitico() {
    return politico;
 }

 public void setPolitico(String politico) {
    this.politico = politico;
 }

 public String getPrueba() {
    return prueba;
 }

 public void setPrueba(String prueba) {
    this.prueba = prueba;
 }
 public void setSession(Map session) {
    this.session = session;
  }
     public Map getSession() {
    return session;
  }
}

in that situation. Actualiza.jsp doesn't show "variable" atribute from
session, using "<%= session.getAttribute( "variable" ) %>". It shows null.

can anybody help me? I'm doing exactly what struts2 FAQ say (How do we
get access to the session).

thanks in advance.

i've tried with

   <%= session.getAttribute( "variable" ) %>
 
and

   <s:property value="#session.variable"></s:property>

and surprise, both works. After closing and opening eclipse 3.4.0 works.
I think this is a bad memory managing of eclipse. Does anybody knows
something about this?

Hi Sergio,
add SessionAware interface to your action.

Best greetings,

public class Actualiza extends ActionSupport implements SessionAware

is that?

thanks for replying

Sergio

Hi,
sorry for too fast response,
i see that it is implementing it,
another thing to notice is that
in action You have access to session field which is a map constructed
by struts, not real session object - as far as i remember.
In jsp you can do < s:property value="session.get('variable')" > to
show key from session in jsp.

Hope that it will help,
Pawel Wielgus.

Hello,

I have an action result type dispatcher with param name location equal to the path to the JSP, but I have precompiled the JSPs and it now seems the dispatcher cannot locate the JSP class. I tried changing the location to the fully qualified class name of the compiled JSP with the same result: There is no Action mapped for action name MyAction (unknown location)

Is there a way to reference the precompiled JSP in the dispatcher?

Any help would be appreciated.

Thanks,
Lee

I guess the main problem is that the request params are gone. So not only if the file not submitted, but none of the params are submitted. The rest of the params need to be made available, imo...

Do you prefer an exception? What would you do with it?

My mistake, there needs to be a slash after the context, otherwise the page
was not loading completely (still not exactly sure way, probably due to
mod_jk - part of the page loaded, but not the s:action tag/dispatcher)

That's odd.

If you were to <struts:write> the actionform's property
when the page is re-rendered, what does it contain?
