Is not a Servlet Exception

I am new to Servlets and am trying to add a sample Servlet to Tomcat 4.0.4. Whenever I try to run it, it gives me one of two errors.
1)The requested service (Servlet RequestDetails is currently unavailable) is not currently available.
2)javax.servlet.ServletException: Class org.stevengould.javaworld.RequestDetails is not a Servlet
I am getting my code from an article I was reading in JavaWorld:
http://www.javaworld.com/javaworld/jw-02-2001/jw-0223-servletweblogic.html
Any help would be great.
Thanks!
Jeremy

I call the Servlet like this: http://localhost:8080/SampleServlet/
Below is the error it gives me:

Thanx in advance.

Hi,
Thanks for the reply.
Yes you are correct, i compiled using jdk1.5.
but my servlet code will not compile in jdk1.4 version since i used advanced vaector classes in that.
Is there any settings like script file that need to be changed so that i can point to my jdk1.5 compiler rather than the default one pointed by weblogic.
Thanks in advance
Ram

Are you able to receive any data in simulator I mean to say are you getting the same exception in simulator too?
Use POST method in place of GET, and check.
What are you passing in the variable data? May be the data size is exceeding the limit.
If you resolved then don't forget to reward!!!

NULL in primary keys NOT logged to exceptions table

Problem: Inconsistent behavior when enabling constraints using the "EXCEPTIONS INTO" clause. RDBMS Version: 9.2.0.8.0 and 10.2.0.3.0
- NULL values in primary keys are NOT logged to exceptions table
- NOT NULL column constraints ARE logged to exceptions table
-- Demonstration
-- NULL values in primary keys NOT logged to exceptions table
TRUNCATE TABLE exceptions;
DROP TABLE t;
CREATE TABLE t ( x NUMBER );
INSERT INTO t VALUES ( NULL );
ALTER TABLE t
ADD ( CONSTRAINT tpk PRIMARY KEY (x) EXCEPTIONS INTO exceptions );
SELECT * FROM exceptions; -- returns no rows
-- NOT NULL column constraints logged to exceptions table
TRUNCATE TABLE exceptions;
DROP TABLE t;
CREATE TABLE t ( x NUMBER );
INSERT INTO t VALUES ( NULL );
ALTER TABLE t MODIFY ( X NOT NULL EXCEPTIONS INTO EXCEPTIONS );
SELECT * FROM exceptions; -- returns one row
I would have expected all constraint violations to be logged to exceptions. I was not able to find any documentation describing the behavior I describe above.
Can anyone tell me if this is the intended behavior and if so, where it is documented?
I would also appreciate it if others would confirm this behavior on their systems and say if it is what they expect.
Thanks.

P.S. Apologies for the repost from an old thread, which someone else found objectionable.

I should have posted the output. Here it is.

As you can see, I get the expected error message. But I only end up with a record in the exceptions table for the NOT NULL column constraint, not for the null primary key value.

[Solved] The requested object does not exist. (Exception from HRESULT: 0x80010114)

I have a 8 node cluster with Hyper-V, which will be 10 nodes when it's finally done.
Recently I've been try to add nodes and though that went fine, after about a week I could not open the Failover Cluster Manager anymore.
After some checking I found out that the latest added node was giving problems.
VM's on the node still run and function properly, but most Powershell commands result in a "The requested object does not exist. (Exception from HRESULT: 0x80010114)".
I can suspend the node with Suspend-ClusterNode, but draining roles was unsuccesful in one case.
In the other there were no VM's on the node so suspending went fine.
What I did find out was that when I tried to ping the node from another, proper functioning node, it took a while before the pinging started. It felt like the interface had to come back online on the problem node.
After that, I could add the cluster to the Failover Cluster Manager. However, Powershell commands still give a 0x80010114 error or a CIM error for when I use Get-NetAdapter.
A reboot resolves the problem, but only for about a week.
I know there is a topic with the same title already, but the wbemtest en rollup update "answer" is totally unclear to me why I should change something with wbemtest, or why to install updates that to me have nothing to do with this problem.
Before I did the ping test from a functioning node I pinged my DC and another node from the problem node just fine.
No waiting at all.
The cluster has three networks. Management (host only), Live Migration and iSCSI (also a VMSwitch for certain VM's).
I have no idea where to look. Evenviewer doesn't give me anything I can work with that I can find...

File does not exist: /servlet/f60servlet

Hi,
We have a Developer 2000 application which is running on 9ias.
Till last week the UAT system was working ok. Since i re-started, it stopped working. The apache error log displays the following error messages:
[Tue Jan 25 15:53:08 2005] [error] [client 3.248.176.44] File does not exist: e:/uat/oracle/806/forms60/java/sun/applet/AppletViewer.class

Please help!
Note: Developemtn and Productions systems with the same setting are working ok.
Thanks,

I am currently using OracleAS 10g and is using mod_oc4j to mount the Forms Servlet.
It seems that you use JServ for mounting the Forms Servlet, (maybe default in 9i R2?) from the error log entry /servlet/f60servlet...
Maybe Jserv is not up and running on your host? It looks like Jserv hasn't mounted /servlet/ or aliased /servlet/f60servlet as the error log indicates that Apache is looking in the filesystem for these paths which is wrong.
But what do I know... :)

RSAR_TRFC_DATA_RECEIVED Function module does not exist or EXCEPTION raised

Dear All,
We have 2 production systems one is a APO server & the other being BW server.
While checking in SM58 of our APO production server we found that so many entries were in error saying "ERROR REQU_<number> PG# 12 In BW" with target system as BWCLNT<CLIENT NO>.
We checked in both the production systems for any job failure w.r.t same time span but could find nothing.
When we tried to solve this by using F6 option to re-execute the LUW it says "Functional Module doesnot exists or Exception Raised". After doing checks it was found out that the Functional Module (RSAR_TRFC_DATA_RECEIVED) was existing . So we need to know about how we can solve this EXCEPTION RAISED issue.
Thanks & Regards,
SAPAPO

How to invoke a jsp page from java which does not use Servlets?

Hello,
I am working in Documentum. I am trying to invoke a jsp page from another java page which does not use Servlets.
I tried doing this by just instantiating the java class related to the jsp page from my present java class.In my java class related to the jsp page, I have defined onInit() and onRender() methods.
Now, I am trying to call the jsp page from my present java class by just instantiating the java class related to the jsp page. This throws a java.lang.NullPointerException.
Any comments or suggestions on this.Any help would be appreciated.
Thanks,
Ranjith M.V

Hello,
Thanks for the reply. One important thing I forgot to mention. I am also using xml component.And?
As this is the standard way used for coding in Documentum, I do not want to use Beans.Well, JSP's should, in and of themselves, contain no functional code. It should all be only display.
Without that is it not possible?What did I say? I said,

Java WSDP 1.4 is not parsing SOAP Exceptions

We used Java WSDP 1.4 toolkit to generate stubs for webservices. We used Tomcat 5.1 as the web container. When methods of the webservice are invoked which do not return SOAP exception responses, WSDP is able to properly parse the response and display the resutls correctly. But when the responses contains SOAP exceptions, WSDP always returns
"java.rmi.RemoteException: Runtime exception; nested exception is: trailing block elements must have an id attribute".
But other toolkits like Axis 1.1,.Net,ColdFusionMX,Glue are returning proper exceptions messages. The following is the exception message received from the other toolkits for the same method invocation.
"Exception has been thrown by the target of an invocation. '1000:Invalid data source name 'invalid_String'"
Apart from Java WSDP all the other toolkits that we mentioned are able to parse the exception message properly and display the same.
Any ideas why the toolkit is behaving like this. All the versions of Java WSDP that have come till date have a similar problem. We would be happy to hear any responses for the problem the we are facing in Java WSDP 1.4. At present we have decided not to use the toolkit for any web service development.

Am specifying the URL of the WSDL file for which we are unable to get proper SOAP Exceptions, whenever they are generated. Whenever we give valid values while invoking the methods, the response is properly parsed, but when a SOAP Exception is supposed to be generated, it generally returns the Runtime exception that we mentioned. Can you please look into it and identify the reason about why it is failing. In case you are able to run it through properly, please attach the code that would make it work properly.
The URL is :

A few things to try:
1-Repair permissions and restart your computer.
2-Zap the PRAM
3-Use Software Update/App Store to update your OS to OS 10.10.3. Also, update everything SU/AS has to offer for your computer. When done, repair permissions and restart your computer.

IDOC send step not running with exception in BPM?

Hello,
hope this is a simple question, but we are running with a problem here which is not answered well in SAP help or sdn. Possibly I didn´t find the right blog.
Situation:
We created a BPM with a send step (IDOC receiver) in a block (after a receive step starting the BPM) (That´s simple so far!).
The send step (async IDOC) in the block is connected in its attributes in field "system error" to an exception branch defined in the same block.
In this except.branch the process should send back to sender system a message via RFC and the last step in this exception branch is to interrupt the proces.
But now we tried to do a test. In this test we modified the receiver address of the send step (IDOC reciver) so that the receiver could not be reached, which results in a system error in SXMB_MONI (Service unavailable).
But this doesn´t work. The BPM starts the send step to the unavailable receiver, SXMB_MONI shows a system error step, but then the BPM continues with the next step after the block without starting the exception branch.
Any idea why the exception branch is not called?
Best regards
Dirk

Hello again,
we are one step further now.
We did the same with an RFC instead of the IDOC send step.
Same result:
The service is not reachable. So the step results in an system error.
But as we could see in the monitoring SXMB_MONI the block with the exception and this send step (RFC) is passed before the step gives back this error!
So it looks like connection problems do not trigger an exception?
Any help is welcome!
Best regards
Dirk
