Strut - global exceptions

does anyone know the syntax for global exceptions in struts?
thnx,
sunsons

Global Exceptions are configured with <global-exceptions> in the struts-config.xml file.
A <global-exceptions> configures the global handling of exceptions thrown by Actions to mappable resources using an application-relative URI path. This can be a specific page designed to handle this exception.

Global Exceptions in Struts

Hi All,
When ever there is an error I need to handle the exceptions gracefully. Since I'm using struts frame work I'm using global-exceptions declarative.
Here is the struts-config.xml where I have included <global-exceptions>
<global-exceptions>
<exception handler="com.hp.chrs.action.ActionExceptionHandler"
type="java.lang.Exception"
key="global.error.message "
path="/jsp/chrs_error.jsp" />
</global-exceptions>
I have written ActionExceptionHandler.java class which is the subclass of ExceptionHandler. In execute function of this I'm logging the error then forwarding it to chrs_error.jsp.
public ActionForward execute(Exception ex, ExceptionConfig ae,
ActionMapping mapping,
ActionForm formInstance,
HttpServletRequest request,
HttpServletResponse response)
throws ServletException {
System.out.println ("Inside execute of ActionExceptionHandler");
logError(ex);
//forward to the jsp
ActionForward forward =
super.execute(ex, ae, mapping, formInstance, request, response);
When ever an error occurs chrs_error.jsp is displayed. But it is not going to ActionExceptionHandler.java class.
What my unerstanding is whenever error occurs it should go to ActionExceptionHandler and then display chrs_error.jsp.
Any inputs are welcome
Thanks in Advance

Most probably its the wrond struts version...you cannot use message resources in struts i.0, might want to change the head of the struts-config.xml to
<!DOCTYPE struts-config PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 1.2//EN"
"http://jakarta.apache.org/struts/dtds/struts-config_1_2.dtd">

No there isn't a global exception handler in JSF. At least none that I've ever heard of or run across. This is something I think JSF dropped the ball on. Maybe in a future release?
I'm afraid you'll have to get creative with error processing. It's tricky with JSF.
The way I did it in my application was to create error pages (as you mentioned). I configured the web.xml to redirect to these error pages if there was an uncaught exception. There are some serious limitations when you forward to a JSF page like this though. First, you need to make your error page have f:subview tags instead of f:view. Then, I couldn't get commandLink or commandButton to work right. The action method never got executed!
You may have already seen some discussions about this. If not, dig around in the forums and you'll find a few good tips.

Global Exception Handling

How to set up global exception handling to provide user friendly messages to user?
AFAIK there is no real global exception handing available for now in ADF. So I need some "tutorials" about exception handling in:
- Model
- Controller
- View

Global Exception Class

Hi,
I have a global exception class which is inherited from already existing exception class.
I would like to use this class to raise different exceptions.
How to use this global exception class to raise exceptions with different descriptions?
can anybody explain or send a material on this?
Thanks in advance...

I guess you have little misunderstanding of the Exception concept.
You have to RAISE the exception from any processing block (Subroutine, Method etc.) and CATCH the exception in where you call the subroutine.
Check this example. In this example, I am raising the exception from the method DEVIDE of the class LCL_TEST. Now, I call this method DEVIDE in the START-OF-SELECTION block. So, here I need to catch this raised exception by the DEVIDE method. In my example I have used the exception class ZCX_GEN_EXC, you may have to replace it with your exception class ZCX_SAMPLE_EXCEPTION.
CLASS lcl_test DEFINITION.
PUBLIC SECTION.
    METHODS devide

Global Exception Handler

Hello,
I've implemented the Global Exception Handler how is saying at http://www.adobe.com/devnet/flex/articles/global-exception-handling.html
Some errors are being catched by it, and others not.
I looked at another thread here, but for him, the Debug Dialog was not appearing because another place was catching the exception for him.
There are some way to catch all errors in just on place?
I need this, because sometimes in production happen errors that we didn't find in development, but stills there.
The SDK is 4.1 and minimum Flash Player for the applications is 10.1.
Regards,
Fredy.

Calling EJBs from Global Exception Handler

Hi, I'm using Weblogic Workshop 8.1.4.
I have a JPF which calls a EJB to set a lock flag (to prevent the JPF being executed twice at the same time.)
I want to reset the lock flag in the global exception handler, however, if I call an EJB (Entity or Session) in a perform node in the exception handler, I get a NullPointerException.
Is this because it's being called in the exception handler? Is there any way to work around this (without building a POJO which does all the persistance logic and SQL calling manually?)
Thanks.

You can redirect stdout to wherever you want by using
System.setOut(PrintStream out). Also, you can give
printStackTrace a PrintStream.
hth,
mI think to solve this problem you should call System.setErr(PrintStream err);

Global exception handler not being called

Hi,
I have a wli process that has a global excepton handler. One of the controls throws a NullPointerException but it is not being handled by the group exception handler nor the global exception handler.
Does anyone have any idea what may be causing this behaviour?
Thanks,
Dale

I have discovered that using -memalign=Ns with N greater than 1 does not work for me. For example, if I remove a VME card from the system and try to use an unsigned short pointer to access a 16-bit register in the card's vacated VME address space, my signal handler gets called when I compile the code with N=1, but for any other N, my handler is ignored and my program cores.
Unfortunately, using N=1 causes other code that works with higher N to fail. I have one VME card where I need to access a register as a 16-bit read. The code the compiler generates to access the unsigned short pointer value results in two single-byte load instructions - this causes the device to cry foul and as a result, the driver raises SIGBUS, which my program handles. For higher N, the compiler generates one two-byte load instruction, and the device is happy to send back the data.
So it would appear there is some kind of problem with -xmemalign=Ns for N > 1. It seems like the SIGBUS handler typically imployed by the compiler to handle the misalignment problems when -xmemalign=Ni is used is being invoked.
Any other ideas?

Tranforming xml in struts giving exception

Hi,
I am using ajax with struts. I have to transform xml into html using xsl stylesheet at server side and send the response to the client.
I am using Transformer for the xml transformation. The whole transformation works fine in a simple java application but when i use it in strut framework it throw exception "could not compile style sheet". Following is the code written in the action class of the struts.

Global exception handling (Web Applications)

Hi,
I want to capture all run time exceptions and store them into a log file.
I have used uncaught error event handler for catching all such run time exceptions.
Application has various components and I have manualy introduced few run time exceptions at various places
I was able to capture these uncaught exceptions only at very few places and even this was not consistent.
Any help will be greatly appreciated.
Thanks,
Abhishek.

How to handle the global exception at servlet filter?

I cannot redirect the page or add the error message to faces context after the rollback. How do I can show the error to the client?
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException {
UserTransaction utx = null;
try {
InitialContext ctx = new InitialContext();
utx = (UserTransaction) ctx.lookup("java:comp/UserTransaction");
utx.begin();
EntityManager em = EntityManagerUtil.getEntityManager();
chain.doFilter(request, response);
em.flush();
utx.commit();
em.clear();
}catch(Throwable t) {
logger.error(t, t);
try {
utx.rollback();
}catch(SystemException se) {
logger.error(se, se);
} finally {
EntityManagerUtil.closeEntityManager();
}

If I send the error code, it will throw the following exception because the response is committed.
java.lang.IllegalStateException
java.lang.IllegalStateException
at org.apache.coyote.tomcat5.CoyoteResponseFacade.sendError(CoyoteResponseFacade.java:433)
at mo.gov.safp.eform.web.filter.EntityManagerFilter.doFilter(EntityManagerFilter.java:57)
at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:230)

at org.apache.catalina.core.StandardContextValve.invokeInternal(StandardContextValve.java:271)
at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:202)
Should I solve it?
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException {
UserTransaction utx = null;
try {
// Define the request and the response encoding.
request.setCharacterEncoding("UTF-8");
response.setCharacterEncoding("UTF-8");
InitialContext ctx = new InitialContext();
utx = (UserTransaction) ctx.lookup("java:comp/UserTransaction");
utx.begin();
EntityManager em = EntityManagerUtil.getEntityManager();
chain.doFilter(request, response);
em.flush();
utx.commit();
em.clear();
}catch(Throwable t) {
logger.error(t, t);
try {
utx.rollback();
}catch(SystemException se) {
logger.error(se, se);
((HttpServletResponse)response).sendError(500);
}

Runtime Error and Exceptions

Hi,
Could you please tell me "What is difference between Runtime Error and Exceptions"
Thanks & Regards,
Krushna Biswal

If you would like to handle and navigate based on the exception type, this code would help you. btw I'm not familiar with portlet though.
http://sourceforge.net/projects/optionzero
http://sourceforge.net/forum/forum.php?forum_id=666191
You can declare exception type and navigation in faces-config.xml in declarative manner like Struts global exception notion.
Please let me know it's useful or not.
thanks,

Handling Exception/Runtime Exception in JSF

Hi,
Any good pointers to documents describing proper error handling.
Not just navigation rules to an error.jsp file but also handling of runtime exceptions and exceptions in backing beans where you cannot use navigation rules (calling a method from JSF EL etc.).
I am developing jsr 168 portlets using jsf on websphere portal.
I can't get the error handling via web.xml to function and other places I can't manually make it go to an error.jsp in case of exceptions.
How to handle the runtime exception in JSF.
1. By including following tags in web.xml
<error-type>
<error-exception></error-exception>
<error-loaction>/error.jsp</error-loaction>
</error-type>
its not working.
2. If include the
<%@page errorPage="../error/GenericError.jsp" %>
in jsp page then
it is not forwading to error page giving asaertion failure exception
If we change the GenericError.jsp tag like
<f:view>
</f:view>
to
<f:subview>
</f:subview>
then it is going to error page but the
action inside the error page is not getting called its backing bean
Here is code of error.jsp
<%-- jsf:pagecode language="java" location="/JavaSource/pagecode/JSPs/ErrorPage1.java" --%><%-- /jsf:pagecode --%>
<%@taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
<%@taglib uri="http://java.sun.com/portlet" prefix="portlet"%>
<%@taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<%@ page isErrorPage="true" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
</head>
<body>
<div class="errorMessage"><%= exception.getLocalizedMessage() %></div>
<f:subview id="name">
<h:commandButton action="#{OSPMTASecurityBean.cancel}" value="submit"/>
</f:subview>
</body>
</html>
