problem with EJB

[Manas Ahlaad]

Hi all,
i created an EJB in a project, i have deleted the EJB and project by going to that directory since there is no option to delete the EJB and project in the UI provided by the websphere server .But I am still seeing the project and beans with lot of errors since no physical files are there since i deleted them.
When i go for creating new EJB the old project which i deleted are still getting displayed and even i select a newly created project , i could not be able to deploy the EJB since errors of the previous project keep bugging me
What should I do ??

hi manas,
There is a uninstall provision available, follow this navigation, expand nodes, under nodes click on "Enterprise Application", there u will get the button to install.
Since u have already deleted the files, that specific application cannot be uninstalled.

[R Krishnan]

hi manas,
can u pls tell me, what purpose this URL serves.

[Manas Ahlaad]

which URL ??

[R Krishnan]

hi manas,
To what, localhost:8080 is mapped to, what u have tried to invoke by entering this.

[Manas Ahlaad]

i did not map anything to that , the server is running on port 8080 , so i should get the default page if i request as localhost:8080
but it is causing problem
when i request as localhost:7000 on which some other service of server is running i could get page

hope u understand the problem

It's your lucky day. I happen to be reading red book and see your error! See section 5.3.1 Virtual hosts of redbook SG24-6198-00.

[Sahil Singh]

HI,
But how does one eradicate that error in WSAD5.0.
Thanks,
Sahil

[Sahil Singh]

Ok that one is solved..
Have another problem.
When trying to load my servlet it gives the following error.
javax.servlet.ServletException: (class: com/sbc/es/xmvc/xml/SaxEnvironment, method: parse signature: (Lorg/xml/sax/InputSource V) Incompatible object argument for method call...
Is is a version - compatiblity issue..?? b'cuz i just trying to run my already running application on WSADV4.0 on to WSADV5
Thanks in advance.

This sounds like a classpath error. My guess is you are picking up WebSphere's XML classes instead of the ones in your EAR. If you are including the XML JAR files for your SAX parser in your EAR file, then set the classloader policy for that EAR file (in the admin console) to be PARENT_LAST.

Hi Kyle,
Thank's for answering and it did help me get ahead.
But now facing another problem.When i try to load the first page,
it gives the following error :--->>
In version WSAD4.0.3 i have JRE 1.3.0
and WSAD5.0 i have JRE 1.3.1. Does this have anything to do with the error.. Thanks In advance once again.......

Still sounds like a classpath error to me. Document certainly is implemented by DocumentImpl. My guess is that there are multiple instances of Document on the classpath.

Sahil, Shiva,
I am still having the same problem you mentioned with "OSEListenerDi E PLGN0021E: Servlet Request Processor Exception: Virtual Host/WebGroup Not Found : The web group / has not been defined".
I have read the note in the redbook note:

Note: When setting up extra virtual hosts, it is important to make sure that
each contains a completely unique host name and port number entries. If
there are wildcards or the same host name is listed in more than one virtual
host, then the application server will not be able to resolve requests and an
error will occur that can be viewed in the WebSphere Administrative Console.
The error that will be seen is:
PLGN0021E: Servlet Request Processor Exception: Virtual Host/WebGroup Not
Found : The web group /xx has not been defined
This is a generic error message and it can mean a number of things, but if you
are positive the server is running, then check the virtual hosts.

Maybe I'm stupid, but I still don't get it. I'm using WSAD 5.1.0 and I have created a very simple Ear project called Test. It contains a very simple TestWeb project. The only thing in the TestWeb project is an index.html page that does nothing but attempt to display the words "Place content here." I have created a Test server and server configuration with the Test ear project added to the server. On the ports tab in the Cell settings section, I have configured a single hostname of '*' and set it to port 80. The server indicates it is open for e-business. When I hit http://localhost, I get a 404 file not found error in the browser and the server console shows OSEListenerDi E PLGN0021E: Servlet Request Processor Exception: Virtual Host/WebGroup Not Found : The web group / has not been defined.
Can someone please explain what is wrong?
Thanks,
Mark

My problem turned out to be the context root setup in the properties for the Web project. I need to change it to be "/".
Thanks,
