[Problem] Define Error Codes in web.xml
Hi everybody!
What I want to do is very simple to explain:
For our web-application I have designed a global error pages, that should appear, whenever an error occurs. Not matter if it is an 500 a 404 or a 202. Always the same page, that does the processing of the error in the background.
In the web-xml if defined it like this: (for example for a 500 error)
<error-page>
<error-code>500</error-code>
<location>/global_error_page.jsp</location>
</error-page>Now I want to alter the web.xml in a way, that this error page is called for all possible error-codes, without writing a whole block for each error-code.
For some reason <error-code>*</error-code> does not work.
And ideas, suggestions?
Thanks in Advance!

i have done it for collecting Database errors but not successful in doing it for Catch errors.
The way to do it for DB errors is to return error through pragma and in try itself store it in a String and use requestDispatcher by setting attribute and getting the same in JSP. But this should be inside try to work.
For Java errors i have defined error code in web.xml
so the possible java errors shows the error page.

Defining error-page in web.xml
Hi,
We are using oracle 9iAS with oc4j container. I have defined error-page for redirecting 404 error-code in web.xml. It works fine with all browsers except internet explorer 5.5 and higher, IE ignores and displays 'page cannot be displayed' page. Can anybody help me on this, but on the otherhand if I send response.sendError(404);, it recognizes and invokes page.
Thanks for the adviceHi,
Thanks for your reply to me.
I am doing something wrong but I can't find it.
I add the following code to my WEB-INF/web.xml file under the web-app tag, using jdeveloper.
<error-page>
<error-code>404</error-code>
<location>notFound.html</location>
</error-page>
then all of my jsp's in my project have this error message when I buit them.
-Error(1): oracle.xml.parser.v2.XMLParseException: Invalid element 'error-page' in content of 'web-app', expected elements '[taglib, resource-ref, security-constraint, login-config, security-role, env-entry, ejb-ref]'.
Can yo help me???

Problems with error-page in web.xml and page caching
Having a few problems with error pages and web.xml with browsers caching the error pages and strange errors coming out of weblogic.servlet.intenal.WebAppServletContext
I'm trying to set a web app up so that all http errors and all exceptions are routed thruogh predefined resources. For now, I'm simply send 400 errors to 400.html and the ServletException, IOException and RuntimeException to respective html pages.
What I'm finding is that the error codes work fine but the exceptions are only be routed to the correct error page for the first call to the servlet after server restart.
So for example, I have my servlet throwing a ServletException as a test case. The weblogic server log shows that ServletException is thrown, and the correct error page for ServletExceptions is shown.
If I change the Servlet code to throw IOException in place of SevletException, the weblogic.log shows that IOExceptyion is being thrown (so the servlet has deployed successfully), however the Servletxception error page is shown on the browser.
I'm using IE6 and I've changed the setting such that a new page is requested every time using the tools-internet options-temp internet files-settings option to "check for new versions of stored pages: Every visit to the page".
Despite this, the servlet exception error page still appears.
If you clear the cache from the temp intenet files->delete files IE option, the correct errror page will be shown so it appears that the browser cache is being used after all.
everytime I delete the temp intenet files I get the correct error page on the first request after but then not after that.
I have implemented the service method for this test to throw the exceptions - does this make a differecne?
As a test, I have moved the imlpementation to the doGet method instead bu I now get a strange eror from weblogic comlpaining about an arrayOutOfBoundsException because eror codes in the web.xml are not supported! - see error above.
Any help is appreciatedAfter further investigation: -
There are no problems with error pages based on error codes, only error exceptions.
As a test case, I have a service method in a servlet throwing either one of the three exception types that servlets can throw (Runtime, Servlet & IO) the following rules apply. The exception to be thrown is hardcoded and is changed and the web app rebuilt each time. The correct web.xml has been deployed to the app server (checked through console). the webapp is being redeployed correctly - this can be seen in the weblogic log, where the correct exception is reported.
I am using WLS 8.1, Servlet 2.3, JDK 1.4.1_02
In all cases, the weblogic log reports that the servlet is throwing the exception as expected.
Despite having set error-page for exception javax.servlet.ServletException, the exceptions are diverted to the error page that has been set up for http error code 500
The error page for ServletException is therefore never reached.
I have the browser set to request pages every time it is asked.
Once the servlet has thrown an IOException, the only way to get the browser to report an IO or Runtime exception error-page is to clear the browser cache. Restarting the server has no effect.
Once the servlet has responded with ANY exception, it is not possible to get it to report a ServletException (which is incorrectly reported as a 500 anyway) unless the cache is cleared. Restarting the server has no effect.
In the case where the servlet throws ServletException, it has no root exception. The servlet 2.3 spec states that if ServletException is thrown but cannot be found in the error pages, the root excpetion will be extracted and the error page list traversed again. Knowing that the RuntimeException error page is correct shown when RuntimeException is throwm, I have nested this inside the ServletException, however error page for http error 500 is still shown.
I don't believe this is a WLS 8.1 problem, as the console shows that the correct exception is thrown each time. this is backed up by the fact that the correct exception page is thrown when the cache is cleared regardless of what exception was previousdly thrown by the servlet. This excludes ServletException which is always incorrectly thrown as a 500. -
hi I have following servlet ..
sevlet :
PrintWriter out = res.getWriter();
out.println("<p>I will throw a ServletEexception now....</p>");
//res.sendError(404, "messagge");
In the above code res.sendError(404, "messagge"); is commented and i get the result as expected, when i call above servlet.
After that i un-comment res.sendError(404, "messagge"); and get error.jsp, since web.xml contains :
<error-page>
<error-code>404</error-code>
<location>/error.jsp</location>
</error-page>
But if i open a different browser and access the above servlet , then i am getting The page cannot be found.
I am getting the following stack trace(sun app server) :

As per the configuration, when exception is thrown out of the application, container tries to display systemError.jsp page. If we want to include the JSF tags in systemError.jsp page, the request should pass through FacesServlet, so in the <error-page> <location> tag systemError page is specified with the extention systemError.jsf though it's actual extention is .jsp
When exception is thrown from the application container invoke the error page but, while rendering systemError.jsf page exception is thrown saying "Exception processing error page "systemError.jsp" "
To solve this problem i've gone through several forums, materials.
In one forum a guy said, JSF1.1 spec has some problem in displaying error pages. To solve this don't write <f:view> tags in the error page, use <f:subview> intstead. By reading this, i again changed the contents of systemError.jsp page replacing <f:view> by <f:subview>. But the error is still repeating.
Finally what i found is, when we use Ajax4jsf in the application, its AjaxViewRender class is throwing exception while rendering error pages configured through web.xml.
So what i did is i changed error page extention from .jsf to .jsp in the <location> tag. Now jsf won't come in the picture and remove JSF related tags from the systemError.jsp page.
<error-page>
<exception-type>java.lang.Throwable</exception-type>
<location>/rc/systemError.jsp</location>
</error-page>

Question about error-code in web.xml
Can you use pattern matching for error-codes?
Instead of
<error-code>401</error-code>
<error-code>403</error-code>

etc..
you could just do
<error-code>4*</error-code>I don't know a replacement for this, but I recommend to post this questione into Servlets section to get more chances for receiving answers...

Having a few problems with error pages and web.xml with browsers caching the error

Custom user defined error codes
Does TestStand use my custom defined error code file that I created in LabVIEW. It is in XML format and works fine with LabVIEW but does not seem to be picked up by TestStand. Do I need to configure this?
Matthew Fitzsimons

Turns out that it does work if your error file is located in the proper location.
The TestStand adapter internally uses the LabVIEW Runtime engine so it expects additional language files under
C:\Program Files\National Instruments\Shared\LabVIEW Run-Time\7.1\Errors\English\.
The LabVIEW development environment expects the additional language files under C:\Program Files\National Instruments\LabVIEW 7.1\user.lib\errors\. I think this will be used when running a LabVIEW application, like an OI, that uses TestStand.
In general NI software places its error files under C:\Program Files\National Instruments\Shared\errors\English\. I do not recommend this location, but if anything is added to it, I think LabVIEW and the RT woul
d picked it up.

Is there a LabView example in the use of user defined error codes?
Specifically, I have a VI that tests four arrays of data against various high/low limits. I have pass/fail outputs for 18 tests. I'd like to combine these into an 'error out' cluster with appropriate error codes and messages, for which I've created an x-errors.txt file.
My first question must be trival - how do I just set the 'status' bit of the error stream to let the general error handler then look up the error desription from the file?
Secondly - I can't find an example of this in the technical resourses, amI missing something?
Thanks,
Mike

http://www.Conekt.netThere is no example program. There is extensive help on how to do this. Here's the basics.
1) There are two ways to define user error codes in LV6.1. If you are using LV6.0 or earlier, only one method is possible.
2) The 6.0 method involves wiring arrays of error codes and arrays of error code strings to the General Error Handler.vi. These codes will be used to explain any error code which is undefined in LV's internal error code database. Error codes reserved for users which are guaranteed not to be used by NI are from 5000 to 9999.
3) The 6.1 method allows you to create a specially formatted error code file on disk that will be merged with the LV error code database each time LabVIEW launches. For help on this, go to LV's online help, and in t
he Index tab, type
"user-defined error codes, in text files"
(without the quote marks)
4) If you want to set an error into the error cluster, use the General Error Handler.vi again. Wire your error code value to the Error Code terminal (the leftmost-topmost corner terminal). Wire the name of your VI to the Error Source terminal, and wire "No Dialog" to the Type of Dialog terminal (left-side, near the bottom). The error code cluster that comes out of this VI will either be the error in (if one was set) or a new error code cluster with your error and the status bit set to TRUE.
5) The attached demo is written in LV6.0.

Problems with jsp-error page in web.xml
Hello everybody, I have a confusing problem concerning the use of jsps as error pages for 404-errors.
I inserted the following lines in my web.xml file:
<error-page>
<error-code>404</error-code>
<location>/personal404.jsp</location>
</error-page>
The problem is: when an 404 occurs, instead of showin the personal404.jsp, the browser tells me that it tries to download a file which it can't (it tries to download the mis-spelled file). When I try to redirect the 404 to a static html-page, as in
<error-page>
<error-code>404</error-code>
<location>/personal404.html</location>
</error-page>
everything works fine.
Please, does anybody have any idea or suggestion, what I am doing wrong?
Thanks in advance,
SebastianHi Ivan,
I tried it, but there wasn't any difference.
I'll try to explain in more detail what happens:
Imagine my application has the following root-path
http://myServerName:port/mainRoot/
When I try the following URL:
http://myServerName:port/mainRoot/pageThatDoesNotExist.jsp, the browser tells me, it tries to download the file pageThatDoesNotExist.jsp from myServerName and that it can't find that file.
The same happens, when I type http://myServerName:port/mainRoot/pathThatDoesNotExist/pageThatDOESExist.jsp, except that the browser tries to download the file pageThatDOESExist.jsp which (again) it can't.
I have located the files 404.jsp and 404.html in the same directory, so I don't think this is a path-related problem, because everything works fine, when I specify the 404.html as the target error page (i.e. the browser displays the 404.html when I type the URLs shown above).
I don't know if I'm making this clear, but maybe you get the idea.

Problems with the tag error-page in web.xml
hi all, here is my code in my web.xml:
<error-page>
<exception-type>java.sql.SQLException</exception-type>
<location>/ex.html</location>
</error-page>
it seems not to work, because my JavaBean where its the code to connect to my database and execute a query has an error i made it at purpose to see if the error page works, my JavaBean reports an error: column name not valid but the error-page didn�t work, i use a servlet which instantiates my JavaBean and then my servlet redirects to a JSP, obviouslly if an error occurs my servlet didnt redirect to any place, here is the code into my JavaBean, if anyone could help me i really appreciate it...
public BeanLista seleccionaCliente()
int nBandera = 0;
BeanList lp = new BeanList();
String cadena = "SELECT CODCLI, APEPATI FROM TESO.CLIENTE WHERE CODCLI like '2001120%' ";
try
context = new InitialContext();
pool = (DataSource)context.lookup("jdbc/PRUEBADS");
catch (NamingException ne)
ne.printStackTrace();
System.out.println("No se ha podido efectuar el Pool de Conexiones");
try
cc = pool.getConnection();
ResultSet rs = cc.createStatement().executeQuery(cadena);
cc.close();
while(rs.next())
BeanPrueba bp = new BeanPrueba();
bp.setCodcli(rs.getString(1));
bp.setApepat(rs.getString(2));
lp.add(bp);
return lp;
}catch(SQLException sql){
System.out.println("A ocurrido un error de SQL");
System.out.println("Error de SQl capturado como : "+sql.getMessage());
//sql.printStackTrace();
return lp;
}Can it be because you are catching your exception? Why don't you try throwing the same exception in the catch block and let the server handle it for you.
Just a guess... Hope it works.

error-page in web.xml not working
In my web.xml I have
<error-page>
<exception-type>java.lang.NullPointerException</exception-type>
<location>/error.jsp</location>
</error-page>
I checked the page works by doing a /context/error.jsp and
the page displays fine (it is a simple jsp page).
I hit a struts action that gives me this in the std output.

I get a 500 error page instead of my /error.jsp page.
I tried adding
<error-page>
<error-code>500</error-code>
<location>/error.jsp</location>
</error-page>
but that doesn't work either.

Any ideas what to try?a. Override your skeletons error.jsp to forward/redirect to your page.
or
b. If you primarily use pageflow portlets Define a shared flow which has an exception handling method and direct it to your page. Reference the shared flow in each of your controllers (i think global.app is deprecated in 10 otherwise you could do this there). this lets you log some additional information, plus gives you the added flexibility of dealing with different exception types
or
c. Override the path to error.jsp in your portlets properties (havent tested)
Note if you are using servlets etc you still need your web.xml java.lang.Exception entry. The reason it doesnt get picked up is because the portal framework is handling the exception

Error deploying when web.xml contains similiar security-constraint elements
I am receiving an error when I include similiar security constraints in my web.xml descriptor. I actually have many security-constraint elements defined but I have narrowed it down to the following two that appear kind of similiar which are causing the problem:
<security-constraint>
<web-resource-collection>
<web-resource-name>ProcessesPosts</web-resource-name>
<url-pattern>/processPost/*</url-pattern>
</web-resource-collection>
</security-constraint>
<security-constraint>
<web-resource-collection>
<web-resource-name>Processes</web-resource-name>
<url-pattern>/process/*</url-pattern>
</web-resource-collection>
</security-constraint>
The error I receive is:

Has anyone seen anything like this? Have I defined something wrong in my web.xml? The exact same web.xml file does work in several other application servers.Hi Jay,
I am not aware of such document for the preview release.
About the concrete problem your investigation was enough detailed so we managed to reproduce and fix it.
Thanks and regards
