Exception Handling in Webservice Client

Hi..I have a webservice (JWS) running on Tomcat and Apache AXIS..which is installed on different sites/locations..I have a search portal (JSP) that will invoke that webservices and return an array of values in SOAP.
My problem is how can my Jsp page as client of webservice..detect that the webservice is down, or the tomcat is not started? I also want to check periodically if the webservice on different site is available (online) or not..if not an email will be automatically send to the administrator..reminding him to start the service..
how can i determined if a webservice is down from my jsp page?
Thanks in advance for your help..

does it returm a value error 404 page cannot blah bla blah?

How to handle exception propagation in webservice client?

Hi ,
Is there a way to catch an exception thrown by Webservice server handler?
We have a situation where we need to handle the exception on the client side thrown by the server handler.
We are using Webspehere webservices created thru RAD 7 and clients are generated using axis 2 code generator tool. We generate WSDL from java class rather than Java from WSDL.
We have vague idea that we can use wsld fault mechanism but does not have much implementation knowledge on it.
Any ideas on this will be great help.
Thanks in advance..

Here is little more detail ::
We have our regular webservices which has some business methods. Also we have a custom handler which extends javax.xml.rpc.handler.GenericHandler to handle requests [public boolean handleRequest(MessageContext context){
return true;
}] for all our application Webservices.
So, in case of any application errors, handler throws an excpetion which we expect it to be caught in the client stub. e.g. if our application throws InvalidDataException with a specific message on it, we expect it to be caught in the client code as InvalidDataException with the original message on it.
Is there a way to achieve this?
Thanks,

Exception handling in synchronous client proxy

Hi, I have a synchronous outbound proxy-web service scenario. If our Post request (unknown data in the receiver) fails, the receiver system returns a 404 error that results in application error in PI. Now, I want know how to handle CX_AI_APPLICATION_FAULT using the standard fault message type (ExchangeFaultData). I couldn't find any reference for synchronous client proxies using this. I hope you can help me out. Thank you.

Hi Mark,
You have a link here How to handle CX_AI_SYSTEM_FAULT in RFC - Code Gallery - SCN Wiki or here https://help.sap.com/saphelp_nw04/helpdata/en/75/a55c3cff8ca92be10000000a114084/content.htm
I dont know what is your exact problem, you can retrieve certain information in the ABAP code but i usually set a generic message like "Connection unsuccessful" because if you debbug the object the information is so technical to be showed to a client.
Hope this helps.
Regards.

Hi, I Found the solution.
Its mistake in SSLConfiguration. End point url is given in IP but in SSL configuration we have give workstation name.
So instead of getting SSLConfiguration issue we got this issue.
Thanks alot.

Exception handling in client proxy

Hi
Can someone please help me with exception handling in ABAP client proxy.

HI
Welcome to SDN
Check this link you wil get information regarding ABAP Proxy http://help.sap.com/saphelp_nw04/helpdata/en/c9/74246d8ad2447799063d39013e9a11/content.htm

Webservices Client, Exceptions and Log4J

Hi all.
Let me explain the setup of our project before asking for a solution on my problem!
We are implementing a project with 2 teams. One team handles everything that has to deal with the front-end and uses a wsdl to generate a webservices client side that is trigger for most of the requests.
Another team creates the complete backend including the webservices server side.
Thus, we (as team one) do not interfere nor guide team two in how they implement things.
Now here's the problem.
Our side uses Log4J to log all the exceptions. There side probably doesn't (we don't know). If however an exception is triggered from within a WebService call, it is not send to Log4J but to the standard System.out !
Is there any way to change this? Because the only thing we do is generate a client from the WSDL and nothing else! We do however catch any exception and store a message in our log files, but before the catch happens, our System.out has already added the WSexcpetion :(
Is this clear in any way?
Anyone?
Thanks in advance,
Kind Regards,
Les.

A web service client written on WLS [1], should work with
service hosted by any vendor, including .Net, AXIS, Sun RI,
etc.
The client code you write in WLS which is based on JAX-RPC [1]
should compile as is on other vendor JAX-RPC implementation.
So, if you are looking for client code portability then JAX-RPC
is your best bet.

I have tried webservices with apache and weblogic7.0 but i realised thatboth was
to be done very specific to servers.I may be wrong. I am trying tounderstand
how can i write a sercive for one server and access using another server.
When i write webservice in java tomcat server, I create a service andregister
as urn name. For a client to access this service, code kind of looks ejbcode
where we lookup the service and call its method. Instead of looking upJNDI name
we lookup urn and access method. Mind you this client uses ORG packagesspecific
to tomcat.
Now when we write a websercice with weblogic we have to create a ear whichhas
webserverice and write a client to access that service, which lookscompletely
diffrent from one that we wrote for tomcat. I am wondering how can i usethe same
client to access both the services. It rarely happens that both side wouldbe
using same servers.
I am sure that there is some mistake i m doing cos webservices is supposeto be
even language independent.
Can you guys help me in resolving this, more questions later ;-)

Dynamic WebService client within a WebService Handler

We have a WebService running on WebLogic 10.3 that has a handler that contains a Webservice client that connects to a set of IIS WebServices.
The client is called with code like this:
QName qname = new QName("http://www.company.com/Webservices/", "UserService");
UserService service = new UserService(url, qname);
service.setHandlerResolver(resolver);
UserServiceSoap uss = service.getUserServiceSoap();
The URL is dynamic, we have different servers that contain different data other than that they are the same. When this is called the first time with URL http://abc it works just fine. If it is called again but this time pointing to URL http://xyz, the client still goes to http://abc. We have check through debugging to ensure that we are really passing the correct URL, and we are. I traced this through a tool called WireShark and can see our client making 2 GET requests to the proper WSDL but then does the POST to http://abc. URLS have been altered to protect the innocent :) This same webservice containing this handler works as expected within Tomcat, it is in WebLogic that things get weird. Any help would be appreciated.
Thanks,

Start by ensuring that your function actually runs when you

Exception handling in rmi in client side

Hello everybody, I'm developing a small client-server application using JDBC and RMI .
I would like to ask if any body can help to know how handle exceptions thrown in the server side and show them for the client.
Any help will be appreciated

I prefer not to have the server's exceptions known to the client. The client only gets the exceptions the client expects. This is part of the server interface which is defined and owned by the client.
So any exception thrown on the server I would handle and rethrow a different appropriate exception up to the client.

WebService Client - how to enable HTTP Compression

Hi
I have written a simple WebService Client. The WebService expects that the WebService clients enable HTTP compression. This is the exact text from the docs:-
""1. Client should be HTTP Compression enabled
HTTP Compression had been made mandatory for API�s. Thus API�s client should
include �Accept-Encoding: zip� header as part of request and should be able to
handle compressed data. Please note that system will send an error message if client
are not http compression enabled saying client should be compression enabled."
I do not know how to enable HTTP compression in the WebService Client. The method called is "GetInstantaneousFlowData". It accepts no arguments and returns xsd:datetime.
The wsdl can be found at:-
http://energywatch.natgrid.co.uk/EDP-PublicUI/PublicPI/InstantaneousFlowWebService.asmx?WSDL

Thanks for your reply.
Could I get clariffication on some more thing?
I am using Axis 1.4 version. And I am able to implement the gzip while doing the following steps.
1) Change the pivote value to CommonsHTTpSender.
<transport name="http" pivot="java:org.apache.axis.transport.http.CommonsHTTPSender"/>
2) public class RetreiveReservationsSOAPBindingStubLocal extends RetreiveReservationsSOAPBindingStub.
I Override the method to support GZIP.
org.apache.axis.client.Call _call = super.createCall();
call.setOperation(operations[0]);
_call.setUseSOAPAction(true);
_call.setSOAPActionURI("retreiveReservations");
_call.setEncodingStyle(null);
call.setProperty(org.apache.axis.client.Call.SENDTYPE_ATTR, Boolean.FALSE);
call.setProperty(org.apache.axis.AxisEngine.PROPDOMULTIREFS, Boolean.FALSE);
call.setProperty(HTTPConstants.MCACCEPT_GZIP, Boolean.TRUE);
call.setProperty(HTTPConstants.MCGZIP_REQUEST, Boolean.TRUE);
call.setSOAPVersion(org.apache.axis.soap.SOAPConstants.SOAP11CONSTANTS);
_call.setOperationName(new javax.xml.namespace.QName("", "retreiveReservations"));
super.setRequestHeaders(_call);
super.setAttachments(_call);
Object resp = call.invoke(new Object[] {retreiveReservationsRequest});
I am able to send and receive the request and response in gzip encoded format.
Now my clarrification is,
Is it possible to set the piote value to CommonsHTTPSender for the transport http through my code?
How could I set the values from code?
Reason is, I don't want to manually edit the axis 1.4's client-config.wsdd
Since this is very critical thing, please please help me.
Thanks in advance.

Delete Statement Exception Handling

EXCEPTION WHEN NO_DATA_FOUND THEN
DBMS_OUTPUT.PUT_LINE('Error: The supplied Notre Dame Student ID = (' || p_shttran_id ||
'), Transcript Request No = (' || p_shttran_seq_no || '), Request Date = (' || p_shttran_request_date || ') was not found.');
END p_delete_szptpsr_1;
Should I have a SELECT statement to use NO_DATA_FOUND ???

A DELETE statement that deletes no rows (just like an UPDATE statement that updates no rows) is not an error to Oracle. Oracle won't throw any exception.
If you want your code to throw an exception, you'll need to write that logic. You could throw a NO_DATA_FOUND exception yourself, i.e.
IF( SQL%ROWCOUNT = 0 )
THEN
RAISE no_data_found;
END IF;If you are just going to catch the exception, though, you could just embed whatever code you would use to handle the exception in your IF statement, i.e.
IF( SQL%ROWCOUNT = 0 )
THEN
<<do something about the exception>>
END IF;In your original code, your exception handler is just a DBMS_OUTPUT statement. That is incredibly dangerous in real production code. You are relying on the fact that the client has enabled output, that the client has allocated a large enough buffer, that the user is going to see the message, and that the procedure will never be called from any piece of code that would ever care if it succeeded or failed. There are vanishingly few situations where those are safe things to rely on.

Java Exception Handling

Hello everyone,
I'm searching for a design pattern / framework to manage exception handling. I'm currently working on a distributed document management system for PC / AS/400, which consists of Commandline clients, a Socket Server and a windows NT daemon in java, which accepts network requests from the Socket Server. Communication is done via serialized Objects.
My Problem is, that exceptions can be thrown either on the server or on the client side and have to be transferred to the user. Error Messages should be read from the database. Exception handling should prefferably take place in a central piece of code, such as the two endpoints of network connections, the SocketServer as service under win32 and another SocketServer as Application on another box, currently with UNIX OS.
thanks in advance for any answers
regards

You should look into Bridge [GOF:151] and Memento [GOF:273].
Bridge allows you to decouple your mechanism from the implementation memento on how to propergate the decoupled exception information.
