Problem in uri references in web.xml

There are quite a few instances where external URIs are referenced in various sorts of files in WebAdmin. For example:
index.jsp:
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" xmlns:bean="BEAN" xmlns:logic="LOGIC" xmlns:html="HTML" xmlns:nested="NESTED" xmlns:custom="CUSTOM" xmlns:c="C" version="1.2">
web.xml:
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">
If Tomcat is running behind a firewall where the URIs are unreachable, it is very likely that Tomcat/WebAdmin will not start or will, at best, start in an impaired state.
Cache all these external reference to local files.
If it is, then download the external reference and update the URI to point to a local resource. For example:
old:
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd
new:
http://emg-vip:12300/xml/ns/j2ee/web-app_2_4.xsd

thank you for these possible problems and solutions.
But are you really sure this problem occurs ?
And URI is not an URL and normally the resources referenced by the URI's are not downloaded anyway.

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 appreciated

After 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.

Problem with mime type in web.xml file

Hi everybody,
I actually got a problem with mime types on Weblogic 6.0 under Linux.
I read the documentation so I added the next lines in the web.xml file in
the WEB-INF directory of my server :
<mime-mapping>
<extension>
doc
</extension>
<mime-type>
application/msword
</mime-type>
</mime-mapping>
<mime-mapping>
<extension>
ppt
</extension>
<mime-type>
application/vnd.ms-powerpoint
</mime-type>
</mime-mapping>
Why can't I retrieve a .doc or .ppt files with an internet browser correctly
? I get only text/plain ...
Can someone help me ?
Regards,
Alexis Berger

I am having the same problem with doc and xsl. I have added this
<mime-mapping>
<extension>xls</extension>
<mime-type>application/vnd.ms-excel</mime-type>
</mime-mapping>
<mime-mapping>
<extension>doc</extension>
<mime-type>application/msword</mime-type>
</mime-mapping>
to my web.xml. I even restarted the server. I still see doc and xsl in binary.
Is there some other setting that needs to take place?
I am using WL6.1 with fixpack 1.
I can see the doc and excel files in the browser if I don't go through the weblogic
server. That just confirms it's not my browser.

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>

[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!
Stef

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.

Servicegen and web.xml

I want to implement Basic Authentication for the webservice.
My problem is servicegen creates the web.xml file. How do I replace the web.xml file created by servicegen with the one created by me.
Is there any attribute like warfile in servicegen
Thanks in advance

Hi Matt,
You can unzip the ear and then unzip the war produced by servicegen. Then replace the deployement descriptors with your own files and re-zip the whole thing.

Problem with the data source and web.xml

I have an issue where JSC is removing my resource reference:
<resource-ref>
<description>Creator generated DataSource Reference</description>
<res-ref-name>jdbc/localOracleDatabase</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
from the web.xml and sun-web.xml.
The application has been working great in the IDE for months then wham, no more data source definition. I try and add the reference manually and the IDE takes it out. I am "NOT" adding it to the .xml's in the build area. Why is JSC removing the data source entry?

This continues to be a problem. The only way that I can get around the problem is to drag a table from the data source onto the design pallete and then the datasource is added back to the web.xml. I can run fine for 10 or 15 runs then the entry is once again removed from the web.xml.
Help please!

JSF web.xml URI Mappings

I've come across something which I need someone to explain. It's not something that I would advocate doing but the behaviour interests me. I have 2 servlet mappings for the FacesServlet in the web.xml.
<servlet-mapping>
<servlet-name>FacesServlet</servlet-name>
<url-pattern>/jsf/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>FacesServlet</servlet-name>
<url-pattern>*.faces</url-pattern>
</servlet-mapping>
If I use the uri <web-context>/jsf/index.faces using Tomcat 6.0.10 the request never returns the index.jsp page.
If I remove one either one of the servlet mappings, the uri <web-context>/jsf/index.faces returns the index.jsp page correctly.
It seems that having 2 mappings that are both applicable to the uri <web-context>/jsf/index.faces causes an issue.
Just wonder if anyone is able to explain this behaviour. It is a problem with JSF or Servlet/JSPs in general. I would have thought that some precedence ordering would have been applicable and the request would be fulfilled even when both servlet mappings are present.
Thanks

Thanks for this. Looking at this I can see why. However one things that still has me puzzled is the following.
I have 2 servlet mappings (this is for experimental purposes only)
<servlet-mapping>
<servlet-name>FacesServlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>FacesServlet</servlet-name>
<url-pattern>*.faces</url-pattern>
</servlet-mapping>
When I submit the url http://localhost:8080/jsf/faces/index.faces the application totally flips out and the request is never serviced. There is an infinite wait. This is because there are 2 mappings which relate to this request. Remove one of the mappings and the application works fine.
I tried a similar mapping using plain servlets ie;
<servlet-mapping>
<servlet-name>TestServlet</servlet-name>
<url-pattern>/test/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>TestServlet</servlet-name>
<url-pattern>*.jsp</url-pattern>
</servlet-mapping>
I submitted the url http://localhost:8080/example/test/index.jsp and it works fine. There is something different occurring in JSF. Does anyone know what is could be?
Thanks

Forte & web.xml problem

Hi there,
I hope what I have is a simple problem to fix. I'm running Forte For Java 4 and developing a web application. When I run a servlet (although it works fine) I am getting a run-time error:
ContextConfig[] Configuration error in application web.xml
java.lang.IllegalArgumentException: Servlet mapping specifies an unknown servlet name ChooseUnit
This has something to do with the fact that I renamed one of my servlets and it didn't update web.xml (when I ran this servlet, it kept trying to use the servlet's old name in the URL). I went into web.xml and added this servlet's new name manually but it still didn't work, so I deleted the offending servlet, making sure that its servlet mappings were also gone from web.xml.
I then made a new servlet of a different name, and every time I run it I get the above error, even though the servlet name in the error no longer exists, nor any reference to it in web.xml.
Anyone got a suggestion as to how to fix this? It seems to be a bug particular to Forte.
Thanks.

Never mind, it seems to have sorted itself out with a reboot.

Reference taglibs in web.xml

Hi,
I'm trying to find a way to avoid having to always reference commonly used taglibs in all my jsps. Its kind of a hassle to manually change all references when the taglib.tld changes name.
I looked at the <tag-lib> element for web.xml and am a little confused as to what purpose it serves. Does anyone know if this is suppose to provide the functionality I want or is used for earlier jsp specifications? Thanks.

Which taglibs are you having trouble with that keep renaming their taglib.tld? Are they custom ones or standard ones available over the net?
There are two methods of doing this, one by specifying a uri inside the taglib (like JSTL does) the second by setting up mappings in web.xml.
The web.xml file can provide a mapping between the uri you specify in the jsp, and the actual tld file.
So for example if you have in your jsp:
<%@ taglib prefix="test" uri="http://my.testtag" %>in web.xml you would have the following:
<taglib>
<taglib-uri>/http://my.testtag</taglib-uri>
<taglib-location>/WEB-INF/mytag.tld</taglib-location>
</taglib>This sets up the mapping between the uri you used, and the actual tld on disk
Now if the name of the tld file changes, all you do is change it in web.xml, and all your jsp pages will point at it.
The better method IMO is to use the <uri> element in the tld file.
For instance taking an example from JSTL 1.1 , c.tld
<taglib>
<uri>http://java.sun.com/jsp/jstl/core</uri>
...The c.tld file is bundled with the JSTL file standard.jar in the META-INF directory.
This lets your jsp page just import the taglib with the uri, and the server will find it in the appropriate jar file. No need for any entries in web.xml to do this.
If the tag library is written half-decently nowadays, they follow this pattern, and installing a new taglib becomes painless.
Hope this helps,

Your DOCTYPE references 2.4, it should be 2.3. WLS 8.1 supports J2EE 1.3 which was servlet 2.3.
Servlet 2.4 is part of J2EE 1.4 and is supported by WLS 9.0/9.1. Also it uses XML Schema not a DTD.

Thanks,

You must declare TestServCon.java on web.xml as you did for the first servlet
and in the sendRedirect use the following code :
response.sendRedirect("TestServCon");//   TestServCon is the servlet mapping you declared in web.xml
//or this
response.sendRedirect("./TestServCon");
