Why i get servlet exception/login servlet not found exception with .ear ?

I am able to deploy my war and after that generating the ear from that. both works fine in local system.
But when i run (Jboss as service[Java Service Wrapper]) it takes war without any problem.But with ear file i am getting servlet not found exception.I can't understand where this problem is coming from.
Even if i take my JSPWIki ear which is running well in production server, this also gives same error.
One more thing, the files, what i am running well in local system i.e. war and ear working fine. (can't test in production server so testing in same kind of testing server) there also getting login servlet not found exception. Even in same location other files which are deployed are working fine.out of 4 at least one is working fine.
I don't undersatnd where this whole problem is .
Please guiide me where sholud i concentrate to solve this problem.

I took the source code including the dll files already added to the project from here:
spazzarama/Direct3DHook
The solution include two projects the one name Capture is class library type and the dll that make the exception is in this project.
I tried now to use the program Dependency Walker on this dll file and it found error/s:
This is the log:
Error: At least one required implicit or forwarded dependency was not found.
Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module.
Error: Modules with different CPU types were found.
Warning: At least one delay-load dependency module was not found.
Screenshot:
It happen only when using/detecting Direct3D 11 . So far only in Direct3D 11, When i use it with a game that run Direct3D 9 it's working fine.
The question is how can i solve this dll problem ? Any site/place to download this dll from ?

SERVLET NOT AVAILABLE

Hello,
I'am running an application builds with jsp and servlet.
My jsp files run well but when I call a servlet I found this error:
HTTP Status 404 - /Application/servlet/net.xnetwork.projet.controller.ControlIdentite

Thanks you for your suggestions.

Servlet not found exception.

I have deployed war file on weblogic server. when i try to fetch some
          servlet from web browser say, http://localhost:7001/myapp/myservlet ,
          sometimes i get the following error " /myapp/myservlet not found ".
          but on the other hand sometimes it does retrieves it properly. Does any body
          know how to solve this problem?
          Any help in this regard is appreciated.
          Thanks

It does appear in iBooks but the dictionary page says "no definitions found".
how can I download the dictionary? please help me as i read books an my iPhone a lot and really need the dictionary!
Thanks in advance,

Siri is not available on the iPhone for because Apple didn't make it so. None of us users here know the reason; speculation is prohibited by the Terms of Use of this forum.
Regardless of the reason, it is NOT available except for the iPhone 4S. If you want Siri badly enough, get a 4S. Complaining doesn't change anything, and none of us here really want to listen to it anyway.

Modified Servlet not visible

Hi,
I created a servlet & then ran it , it worked fine. After that I modified it so that it should display a different message on browser but its displaying the previous staff. Strangely even if I delete the servlet & then try to access it using a URL , I will see the same stuff which present in the servlet before starting the tomcat. However if I stop tomcat & hen restart it again I will see the modified servlet or error message if servlet not available. How can I get around with this prob of viewing the modified servlet without restarting the tomcat.
Zulfi.

add reloadable attribute to the Context entry in conf/server.xml. by default it does not include reloadable, change
    
    <Context path="" docBase="ROOT" debug="0"/>to
    
    <Context path="" docBase="ROOT" debug="0" reloadable="true"/>this will tell tomcat to reload the servlet after being modified without restarting server.

RE: SSL implementation not available (Https)

I tried to use https from within a jsp with WLS 5.1
using Suns JSSE but at least all i could produce
was an SSL implementation not available exception.
After converting the jsp to an application
i get an:
java.net.SocketException: Socket closed
at com.sun.net.ssl.internal.ssl.SSLSocketImpl.a
Classpath and other installment procedures are the same,
so i guess it has to do with wl environment.
Besides:
Does some support stuff read and care about this stuff?
Or even anybody else?
Bye, K

You mean HTTPS from WLS to somewhere else?
On your weblogic.policy file, add the following permissions ( the last
two permissions shown below ):
grant {
// Permission "enableSubstitution" needed to run the WebLogic console
permission java.io.SerializablePermission "enableSubstitution";
// Permission "modifyThreadGroup" required to run the WebLogic Server
< .... snip ..... >
permission java.util.PropertyPermission "javax.net.ssl.trustStore",
"read,write";
permission java.util.PropertyPermission
"java.protocol.handler.pkgs", "read,write";
Then either dynamically or statically add the providers. I prefer the
dynamic method:
Security.addProvider(new sun.security.provider.Sun());
Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
Finally, enable HTTS:
System.setProperty( "java.protocol.handler.pkgs",
"com.sun.net.ssl.internal.www.protocol" );
One more note. You can simply put all the jar files of JSSE within your
WEB-INF/lib directory. No need to modify any CLASSPATH or any
environment variables.

SSL implementation not available ... Help!

Using WLS 7.0 SP2 on HP-UX and when attempting to establish an outoing SSL connection
I receive an "SSL implementation not available" exception.
In the International version of WLS 7.0 I am able to establish the SSL connection,
but when the same application is loaded into the same version of the Domestic
WLS, it produces the exception.
Usually I expect that exception when there is no appropriate CSP (Cryptographic
Service Provider) entry in JAVA_HOME/jre/lib/security/java.security? How does
one configure a Third Party CSP (Cryptographic Service Provider) for use in WLS?
I am trying to use the Sun CSP.
The code snippet that works on International WLS but not in Domestic WLS is below:
String target = "https://localhost/testApp/NotificationServlet";
URLConnection urlc = null;
URL targetWebService;
// load input file
// Construct the URL using the HTTPS URL stream handler
targetWebService = new URL(null, target, new Handler());
java.security.Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
urlc = targetWebService.openConnection();
urlc.setRequestProperty("Content-Type" , "text/xml" ) ;
((HttpURLConnection)urlc).setRequestMethod("POST") ; // It's a post request
urlc.setDoOutput(true);
urlc.setDoInput(true);
OutputStream os = urlc.getOutputStream() ;
os.write ( buf ) ;
os.flush() ;
os.close() ;
} catch (IOException ioex) {
System.out.println("PBM_APPLICATION_0252 Unable to connect to " + target
+ " " + ioex.getMessage());
} catch (Exception ex) {
System.out.println("PBM_APPLICATION_0252 Unable to connect to " + target
+ " " + ex.getMessage());
Thanks.

In 7.0 SSL implementation used by weblogic tries to use JCE provider before defaulting
to its own. So, you should be able to make it use Sun's provider by moving it
in front in java.security file, or doing the same through api. In any case, even
when no JCE provider is configured, it should not fail. One of the reasons it
could fail, though, is if you do not have proper SSL license (i.e. trying to do
domestic strength encryption while having export license), but I think the error
message would be different in this case.
Are you passing weblogic.net.https.Handler to URL constructor? If yes, you can
try to set ssl debug flags on to get more info about the failure: -Dssl.debug=true
-Dweblogic.StdoutDebugEnabled=true

Why is Siri not available on the iPhone 4

If Siri is software, why is it not available on all iPhones? I remember when the 3GS came out and we got video but not on older phones yet there where hacks available for older phones that allowed video. Is this the same scenario where Apple is trying to force hardware upgrades in order to benefit from new software when it really isn't necessary?

Siri is not available on the iPhone for because Apple didn't make it so. None of us users here know the reason; speculation is prohibited by the Terms of Use of this forum.
Regardless of the reason, it is NOT available except for the iPhone 4S. If you want Siri badly enough, get a 4S. Complaining doesn't change anything, and none of us here really want to listen to it anyway.

"Servlet pluto is not available" error page after deploying portlet

I want to build a JSF portlet with JSC 2.1. I am playing with the tool a little bit and I am experiencing this error after running the project:
HTTP Status 404 - Servlet pluto is not available
type Status report
message Servlet pluto is not available
description The requested resource (Servlet pluto is not available) is not available.
Sun-Java-System/Application-ServerIt's strange because it happened when I changed something in the code of the SessionBean1.java. Since then, I can't even run properly a blank JSF portlet project that I created afterwards.
I created a new project, added nothing and pressed Run Project. It seems, that the deployment was OK:

No, I haven't figured it yet. And it seems that nobody ever had.
JSCreator is buggy. If it weren't for free, I would have never use it. It has so many issues, you will see so many exceptions and experience so many annoyances... And of course, it is very hungry for resources. I am sure that a lot of people will disagree, but that's my opinion. I've been using Eclipse for 4 years now.
However here are some tips (Windows only):
Delete directory .Creator from Documents and Settings.
Uninstall creator, install creator. Don't install it to Program Files, install it to C:\Sun or smth like that, the space character can do some mess.
Again, put your project somewhere, so the path would not contain spaces.
Sometimes just restarting the server helps. I've had to reinstall Creator three times yet.

SOLVED - Servlet MessageBrokerServlet is not available on Ubuntu AMD64

Hello,
I have downloaded blazeds-bin-3.3.0.11688.zip and deployed blazeds.war on winXP tomcat 6.20.
There http://localhost:8080/blazeds/messagebroker/amf url in browser gives me blank screen as expected.
My production deployment will be Kubuntu 9.10 AMD 64 so I wanted to test same on it.
The installation for same is Kubuntu 9.10, tomcat 6.20 installed through repositories.
I deployed same .war in catalina/localhost but I get following error
Servlet MessageBrokerServlet is not available
instead of blankscreen as expected.
What might be wrong ?

There is No Problem with either BlazeDS, Tomcat or Kubuntu OS as such.
The repository Install of Tomcat has the problem. What I did is as follows.
1. First I removed the repository Install of all Tomcat packages.
2. Downloaded the stable tar.gz distribution from Apache website.
3. Followed Instructions at this Link (states that repository Install of tomcat do not work properly.)
4. deployed the blazeds war on linux
5. Started Tomcat and tested http://localhost:8080/blazeds/messagebroker/amf
It gave me blank screen as expected.
Hope this helps to someone who stumbles on Ubuntu Linux Blazeds Installation.
Moderators may put this in FAQ section so that it helps Ubuntu Users.
Thanks and best Regards

It's not that hard to fix/work around, you just need to add a line in /etc/default/tomcat6, I just made a post about it.

Servlet "X" is not available

I have a simple application. I'm trying to follow the MVC Pattern.
I receive the following messages.
HTTP Status 404 - Servlet Bla is not available
type Status report
message Servlet Bla is not available
description The requested resource (Servlet Bla is not available) is not available.
Apache Tomcat/6.0.20or sometimes I receive
javax.servlet.ServletException: Wrapper cannot find servlet class pachet.DispatcherServlet or a class it depends on
SEVERE: Allocate exception for servlet Bla
java.lang.ClassNotFoundException: pachet.DispatcherServlet
20.09.2009 11:56:39 org.apache.catalina.core.StandardWrapperValve invokeweb.xml
   <servlet>
        <servlet-name>Bla</servlet-name>
        <servlet-class>pachet.DispatcherServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>Bla</servlet-name>
        <url-pattern>/dispatcher</url-pattern>
    </servlet-mapping>I'm using an IDE and if I would change, let's say the package name from the web.xml, it would warn me that the path is wrong, but in this moment, I don't receive any warning about anything.

The error message seems clear enough:
Wrapper cannot find servlet class pachet.DispatcherServlet or a class it depends onIs your class called DispatcherServlet in the package pachet? Double check the spelling - remember it is case sensitive.
Is that class deployed in your web application? WEB-INF/classes/pachet/DispatcherServlet.class?
What dependencies does your class have? What classes need to be present for it?
Are all of them available in the web application classpath?
