Trying to invoke Apache SOAP 2.3.1 RPC services

I have several legacy apache SOAP 2.3.1 RPC services I am trying to invoke using a synchronous BPEL process. The services are invoked (confirmed by tailing the log on the machine hosting the service) , however, the return value is null in all cases.
I used the snoop utility and I verified a response is indeed being returned, so I am perplexed as to why BPEL is not able to interpret the response.
Any help/ideas would be appreciated as I would prefer not to have to rewrite these services.
Thanks,
RM

Did you specify the correct message type for your return variable?
<Invoke_1_Authenticate_OutputVariable>
<part xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="Result">
null
</part>
</Invoke_1_Authenticate_OutputVariable>
As is returns:
<ns1:AuthenticateResponse
xmlns:ns1="http://vitalstream.com/webservices" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<return xsi:type="xsd:int">1</return>
</ns1:AuthenticateResponse>

Apache SOAP 2.2 and WL 6.1

When trying to use Apache SOAP 2.2 with WL Server 6.1, I get the following error
when attempting a call.invoke():
"Unable to resolve namespace 'SOAPSDK3'"
I can successfully make the SOAP call using a stand-alone application (not inside
weblogic). I found the following FAQ which described the same problem for WL
Server 6.1 (beta):
http://xml.apache.org/soap/faq/faq-for-WL6.1beta.html
I have not been able to get a working solution though. The XML Registry was already
setup as described, using the org.apache.xerces.*. I also put xerces.jar in front
of weblogic.jar in the WL Classpath (not sure if this would have any effect).
Originally, I had put XERCES 1.3.1 there and had no problem starting WL, but
got the same error as before - Unable to resolve namespace 'SOAPSDK3'. When I
placed another version of XERCES, namely 1.4.3 - I could not even start WL properly,
it crapped out with a memory exception and quit the JVM. I read on WL docs that
XERCES 1.3.1 is required and you cannot put another version in front of the weblogic.jar,
otherwise you have problems (they were right on that one). Here are the WL docs:
http://e-docs.bea.com/wls/docs61/faq/xml.html
So, I'd be interested to see if you anyone has suggestion as to what I might try.
It appears that I MUST use XERCES 1.3.1, but when I put the in front of weblogic.jar
I don't solve the problem. If you know of anything I might try, please let me
know. Thanks.
Configuration:
WL 6.1 on Windows 2000 - application inside EAR file.
SOAP Client - Apache SOAP 2.2
SOAP Server - MS SOAP Toolkit (ISAPI - VB dll)

Thanks,

you are calling wrong the Service.
¿what kind of service do you have? RPC? Document?
ir your target service its document, I recommend this:
1. Test target service with OSB
2. copy XML request and XML response from the test.
3. use XML request format that you got at Step 2 in your source service and using it at your "Service Callout".

Trying to invoke HTTPService with SOAP request

Hi all,
I have been trying to invoke a HTTPService with a SOAP request.
Most of the times I get an error saying that the client has invoked
HTTP with get instead of a POST eventhough my code takes care of
it. Any clue on this? I have copied the code snippet below which
has the SOAP request in a variable message.

I am not using any wsdl file. I'm trying to invoke a webservice that is at client's end (using RPC call). Mine is a generic server program. When i'm calling other clients using the same method, im not facing any issues. Only for 1 particular end-point i'm getting the above exception. Any suggestions?

Exception javax.xml.ws.soap.SOAPFault when trying to invoke OBR

Hi,
1 .I am have created a SOA Composite which has an OBR. I deployed that project and that was working fine.
2 .In Order to call the OBR service from another composite I have created another composite in which a web service(reference) adapter which is towards the right side of the composite shall call the web service of the OBR composite.
When I point the URL to the WSDL of the OBR web service, I get the error. The screenshot of the error is avbl at the following URL. http://img199.imageshack.us/img199/7015/37887205.jpg
3 .So I have manually saved the WSDL of OBR web service as a file and saved it in the proj that i mentioned in 2. Then I was able to create web service adapter with out any problem. Then I created a composite (screenshot http://img59.imageshack.us/img59/7826/30673557.jpg ) which calles the OBR web service and gets the reply.
4. After deploying the composite, when I am trying to invoke the OBR service, I get the following error in the console of the Soa server.

Hi,
The problem is solved now. While creating the WS adapter in Jdev, I have tried specifying the URL with the Ip address instead of server name. seems Jdev was not able to resolve the name of the server. Once I created composite with this and deployed the error got resolved.
Thanks,
Raj

In 903 Oracle SOAP ( based on Apache SOAP) is not configured by deafult, since Oracle SOAP is a depricated feature;
Prefered way of building web services is using 'J2EE Web services'. But if you stilll want to use Oracle SOAP web services
You need to depoy the Oracle SOAP application that is there in soap directory.

Odata JDBC Service: getting NullPointerException: while trying to invoke the method

Hi,
I am testing OData, for that I followed the steps given in this tutorial:
http://scn.sap.com/community/developer-center/mobility-platform/blog/2014/06/10/creating-an-odata-service-based-on-sap-gateway-soap-jdbc-and-jpa-data-sources-ba
It wasn't working as it should, so to understand it better, I created a new project with Stock table only.
Manually entered all it's properties and then deploy it.
Issue1: when I create a JDBC connection to connect with derby database, The driver field has maximum limit and whole driver string is not copied. Attached is the screen shot.
Where as I need to enter: org.apache.derby.jdbc.ClientDriver.
Issue 2: I can't test the connection from here, weather it's working fine or not ?
Issue 3:
When I deploy the project and test the result, I get the Stock Service, But when I try to run this, I get nullpointer exception.
URL: http://localhost:8080/gateway/odata/sap/WSTest1;v=1
Response:
<?xml version="1.0" encoding="utf-8"?>
<service xml:base="http://localhost:8080/gateway/odata/sap/WSTest1;v=1/" xmlns="http://www.w3.org/2007/app" xmlns:atom="http://www.w3.org/2005/Atom">
<workspace>
   <atom:title>Default</atom:title>
   <collection href="StockSet">
   <atom:title>StockSet</atom:title>
   </collection>
</workspace>
</service>
Now I need to run StockSet, so next url to access the stock list,
to get stocks:
http://localhost:8080/gateway/odata/sap/WSTest1;v=1/SAP/StockSet
Now I get the following response:
    <?xml version="1.0" ?>
    <error xmlns="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata">
    <code>
    </code>
    <message xml:lang="en">java.lang.NullPointerException: while trying to invoke the method java.lang.Object.hashCode() of a null object loaded from local variable 'k'</message>
    </error>
I am not able to figure out, why I am getting this error and how to fix it.
All I want is to create a ODAta on ESPM_STOCK sample table given in example.
Looking forward to hear from you.
Thanks.

Issue1: when I create a JDBC connection to connect with derby database, The driver field has maximum limit and whole driver string is not copied. Attached is the screen shot.
Are you working on SMP3.0 (lower version than SP03)?
If yes, then there is character restriction in SMP3.0 (SP00, SP01), maximum length for a database driver is 25 characters.
e.g. if driver name is oracle.jdbc.driver.OracleDriver but when you enter this, then you will see onlyoracle.jdbc.driver.Oracle
Until unless we pass the correct driver value things will not work. there is a workaround for this. You create a desitnation with restricted character length.
You would be seeing a property file for each created destination underC:\SAP\MobilePlatform3\Server\config_master\service.destinations\destinations
Go there and open the created "OracleDB" and edit the "DriverName" to the full string:oracle.jdbc.driver.OracleDriver
Please go through this blog for more understanding:
http://scn.sap.com/community/developer-center/mobility-platform/blog/2014/01/09/how-to-connect-an-oracle-db-with-integration-gateway-in-smp3
Note: seems this problem has been resolved in SMP3 SP03
Issue 2: I can't test the connection from here, weather it's working fine or not ?
I didnt find a way to test a destination. So you have to be sure about what all values you are entering.
Once you are done with Destination creation, map it to the respective deployed service under "services" tab.
Issue 3: When I deploy the project and test the result, I get the Stock Service, But when I try to run this, I get nullpointer exception
Make sure you have corrected "Database driver" name manually. And then check if you are facing same issue.
Does this URL expect any input parameters?
http://localhost:8080/gateway/odata/sap/WSTest1;v=1/SAP/StockSet

Package org.apache.soap does not exist

Hi,
I'm trying to deploy a webservice made out of stateless session bean.
When i run the service by invoking its method through browser then I get an exception as
Servlet error: Cannot generate Class:
package org.apache.soap does not exist

"invalid request" when calling Apache Soap 2.2 webservice using 8.1.1

I have tried setting soap-style to RPC as advised in the documentation but keep
getting this same error. Server is Apache Soap 2.2. Another test client using
Apache Soap 2.3.1 got the same error. I am trying to call a webservice in a WLI
process flow. I have generated the web service control from the wsdl. Error follows:
<01-Oct-2003 11:04:04 o'clock EST> <Warning> <WLW> <000000> <Id=bank_so_11; Meth

Hi Jerry,
There is not much to go on here to help solve your problem. Can you
successfully invoke the external service from Workshop's Test View? If
this works OK you might ask your question to the integration newsgroup
and see if they have some insight:

Hope this helps,

Synchronous BPEL process calling apache soap 2.3.1 service(s) on jboss

I have a problem that is quite frustratiing. I have a very simple synchronous BPEL process and I am trying to invoke some legacy services we have deployed using Apache soap 2.3.1 running on jboss. The process executes, the service executes, but the return value is not received by the BPEL process.
I used obtunnel to capture the data flow and everything seems fine from that perspective. The problem is, if you watch the monitor, the status says active, but the BPEL process returns immediately. It does not wait for the response, so the return value winds up being null. I have tried this numerous times with several services and the result is always the same. This is a serious problem for us. Any suggestions/insight would be very much appreciated.
Ina case there are any doubts as to whether or not it is actually a synchronous process, from the BPEL code:

Below is an example from obtunnel:

As you can see, the value is indeed returned from the service, but BPEL indicates a null value for the return:

Did you specify the correct message type for your return variable?
<Invoke_1_Authenticate_OutputVariable>
<part xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="Result">
null
</part>
</Invoke_1_Authenticate_OutputVariable>
As is returns:
<ns1:AuthenticateResponse
xmlns:ns1="http://vitalstream.com/webservices" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<return xsi:type="xsd:int">1</return>
</ns1:AuthenticateResponse>

WSDP w/ Apache SOAP-RPC

Hi,
Has anyone tried to develop/deploy a web service under WSDP and invoke it from a client app written under Apache SOAP-RPC? Can this be done w/ or w/o 'axis'
from Apache-SOAP?
Thanks,
Marcia

yes, this can be done ...and even vice versa.
This is just a soap call and it dees not matter from where it is called.
Generate the webservice and deploy it. Use the WSDL generated to create the client with Apache Soap. Point to the end point URL for the webservice made with JAX-RPC.
I tried by creating a webservice with Apache Soap-RPC and accessing through the client made with Jax-RPC.
regards
