How to get MyException from ExceptionHandler
I want to implement an application specific exception handling for my struts
application. So, I defined my own Exception class that extends a normal
Exception by an error code and the filename where the exception occured:
public class MyException extends Exception
{
private int errorCode = -1;
private String file = null;
public MyException() { super(); }
public MyException (String message, int errorCode, String file)
{
super(message);
this.errorCode = errorCode;
this.file = file;
}
public int getErrorCode () { return errorCode; }
public void setErrorCode (int errorCode) { this.errorCode = errorCode; }
public String getFile () { return file; }
public void setFile (String file) { this.file = file; }
}
I've also created my own ExceptionHandler class:
public class MyExceptionHandler extends ExceptionHandler
{
public ActionForward execute (Exception ex, ExceptionConfig config,
ActionMapping mapping, ActionForm formInstance,
HttpServletRequest request,
HttpServletResponse response)
throws ServletException
{
...
}
}
In struts-config.xml I've configured this exception handler as a
global-exception that should handle ALL excetions:
global-exceptions
exception handler=de.fortu.actions.MyExceptionHandler
type=java.lang.Exception
key=global.error
path=/jsp/error/error.jsp
scope=request /
/global-exceptions
Now I generate a NullPointerException and throw my exception
object:
try
{
String str = null;
str.charAt(0);
}
catch (Exception e)
{
throw new MyException (Test, 100, MyAction);
}
What I see is that I run through MyExceptionHandler class, i.e. the
global-exception definition seems to work.
What I do NOT see is MyException class. When I stop in MyExceptionHandler and
inspect the Exception object I do not find the values I set in the catch
block before. The detailMessage says:
Error calling form action handler: metrics_onDrilldown reason: null
Any ideas what's going wrong here?
Best regards,
Ralf.

Application specific Exception Handling
Hi,
I try to implement an application specific exception handling. Therefor I
created a class that extends ExceptionHandler and my own Exception class that
has variables for holding an error code and the filename where the exception
occured.
When I generate a NullPointerException I generate a new object of my exception
class an throw it. Unfortunately, in the exception handler class I only see
an object of class Exception. So, I'm not able to get the error code and the
filename from the exception object. When I try to cast the exception
explicitly to my exception class I get a ClassCastException.
How can I get an object of my own exception in the exception handler?
Regards,
Ralf.
struts-config.xml:
global-exceptions
exception handler=de.fortu.actions.FortuExceptionHandler
type=java.lang.Exception
key=global.error
path=/jsp/error/error.jsp
scope=request /
/global-exceptions
ExceptionHandler Class:
public class FortuExceptionHandler extends ExceptionHandler
{
public ActionForward execute (Exception ex, ExceptionConfig config,
ActionMapping mapping, ActionForm formInstance,
HttpServletRequest request,
HttpServletResponse response)
throws ServletException
{
String property = null;
String path = null;
if(config.getPath() != null)
path = config.getPath();
else
path = mapping.getInput();
ActionForward forward = new ActionForward(path);
ActionError error = new ActionError(global.error.nosession);
storeException (request, property, error, forward, config.getScope());
return forward;
}
}

Multiple Resource Bundles
Hi, I try to use multiple resource bundles that get the strings from a database in an environment using JBoss, Struts and Velocity. I have defined two message-resources in struts-config.xml: message-resources factory=com.bk.web.struts.BKWebStringResourceFactory parameter=StringResources key=Strings/ message-resources factory=com.bk.web.struts.BKWebMessageResourceFactory parameter=ApplicationResources/ During startup of JBoss the createResource() method of both factories is called. But when I call a page on which the strings come from the StringResources bundle the getMessage() method of the ApplicationResources bundle is called. In the HTML code I've placed calls like this (: $msg.get(global.close, StringResources) msg is defined in toolbox.xml: tool keymsg/key classorg.apache.velocity.tools.struts.MessageTool/class /tool What's wrong with my call of $msg.get()? Did I miss anything? Best regards, Ralf. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
MessageResources Problem in Action
Hi, I want to access the strings in a resource bundle from within an action. I have two resource files (ApplicationResources.properties and ApplicationResources_de.properties) and they are accessed correctly from the JSP, but not from the action. When I look at the locale with request.getLocale() in the action I see that it is set to de_AT. This is what I expected. Unfortunately, the strings are fetched from ApplicationResources.properties, not from ApplicationResources_de.properties as they should be. I use this code to get a string from the resource bundle: MessageResources messages = getResources (request); String msg = messages.getMessage(rights.new); Any ideas what might be the problem? Thanks, Ralf. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Thanks, works fine! The only thing I have to manage now is to automate this task within Eclipse 3.0M8. At the moment, there is no build.xml file in my project. So, Eclipse must somehow know what to do with the resource files as they are copied automatically from the source to the classes directory when they are saved. How can I tell Eclipe not only to copy them but to run native2ascii? Ralf. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: How to use resource bundle in attributes
But this is not the way I want to use it. This way, I could use it to put a
translated text into the body of a tag like
tdfmt:message key=login/td
But how can I use the translated text as an attribute value as written before?

I am not 100% sure but I believe that you just use the fmt:message
tag.
Just use something like...
fmt:message key=login.tooltip.username /
if you need to send parameters just put them in the body of the tag.
fmt:message key=login.tooltip.username
fmt:param value=${username}/
/fmt:message

I looked into the Java Web Services Tutorial, but the chapter about
internationalization with JSTL only describes the use of
internationalized
strings in the body of a tag (e.g. fmt:message ...).

Special Characters (german Umlaute)
Hi, my web application loads german strings from a resource bundle. Unfortunately, the special characters (german Umlaute like , , ) are displayed incorrectly if they come from the resource bundle. When I write them directly into the HTML code they are displayed correctly. At the beginning of my JSP file I have this line: %@ page contentType=text/html; charset=UTF-8 % And the HTML block is opened with this line: html:html locale=true xhtml=true What do I have to change to get the special characters displayed as they were written in the resource bundle?

Hi, I'm new to Struts and I'm trying to install Struts 1.1 with Tomcat 5.0.16 and Apache 2.0.48. The documentation only talks about Tomcat 3.x. My first try was to follow these instructions for Tomcat 3.2.1. I copied the war files included with the binary distribution into the webapps directory of my Tomcat installation. Then I restarted Tomcat, but the file tomcat-apache.conf is not generate as described in the docs. So, I assume the installation works a bit different with these newer versions, but how? I that described anywhere? And if yes, where? Any hint would be apreciated, Ralf. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
