Message resources and struts modules

[Jeremy Tukif]

Hi all,

I have an application with several modules.
In one of these modules, I defined the two following message resources:
<message-resources key="context" null="false" parameter="blabla.context.ApplicationResources"/>
<message-resources key="menu" null="false" parameter="blabla.menu.ApplicationResources"/>.

And in my JSP, I have:
<bean:message bundle="context" key="myLocale"/>
=> When I want to display the page, I get the following error: "Cannot find message resources under key 'context'"

However, if I add the module context path, it works:
<bean:message bundle="context/path_to_my_module" key="myLocale"/>.
I'm quite surprised that struts does not add this "path_to_my_module" by itself..., and I don't like the idea to "hardcode" my module path in each <bean:message> bundle property...

Thanks in advance,

I also need to resolve this.

Anyone have a solution to this?

I digged into the pageContext. I found this below which I will use as a workaround now.

<br> <br>===================================================================== <br>===================================================================== <br>===================================================================== <br> <br><%="org.apache.struts.action.MODULE attr prefix"%>="<%=((org.apache.struts.config.impl.ModuleConfigImpl)(pageContext.getAttribute("org.apache.struts.action.MODULE",pageContext.REQUEST_SCOPE))).getPrefix()%>" <br> <br>===================================================================== <br>===================================================================== <br>===================================================================== <br> <br>attrs = pageContext.getAttributeNamesInScope(pageContext.SESSION_SCOPE ); <br> <br>

In summary, the module prefix is in the request context.

Example: if your module name is APPLE, the above will return /APPLE

that is, with a slash.

I created a custom tag. (geez, i am hoping i researched enough that there is no existing tag like this....or im wasting my time)

  
package a.common.taglib;

/*
Author:  Angeles Jesus Jr. Calimlim, Singapore
*/

import java.io.*;
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;

public class Struts1ModulePrefix
  extends TagSupport
{

  public int doStartTag() throws JspException
  {
    printStruts1ModulePrefix();
    return SKIP_BODY;
  }

  public int doEndTag() throws JspException
  {
    return EVAL_PAGE;
  }

  private void printStruts1ModulePrefix() throws JspException
  {
    try {
      pageContext.getOut().print(((org.apache.struts.config.impl.ModuleConfigImpl) (pageContext.getAttribute("org.apache.struts.action.MODULE", pageContext.REQUEST_SCOPE))).getPrefix());
    }
    catch (IOException ioe) {
      throw new JspException("Error:" + ioe.getMessage());
    }
  }

}

usage

<app:struts1ModulePrefix/>

tag lib section

<tag> <name>struts1ModulePrefix</name> <tagclass>a.common.taglib.Struts1ModulePrefix</tagclass> <bodycontent>empty</bodycontent> <info> Print slash prefixed prefix of struts module for struts 1 </info> </tag>

A couple of weaknesses for the above solution is if you happen to use for some reason, iframe and window.open to open a jsp directly without passing through struts, as the request context wouldnt contain the struts attribute we need.
