NWDS Webservice help required

[Former Member]

I have created a simple web service which

has JCO code in it...I deployed this web

service using NWDS web services perspective..

I created a client to call this web

service method which has JCO code in it ...

but it throws the exception as follows

javax.xml.rpc.soap.SOAPFaultException: com/sap/mw/jco/JCO$Exception

at com.sap.engine.services.webservices.jaxrpc.wsdl2java.soapbinding.MimeHttpBinding.buildFaultException(MimeHttpBinding.java:651)

at com.sap.engine.services.webservices.jaxrpc.wsdl2java.soapbinding.MimeHttpBinding.processDocumentFault(MimeHttpBinding.java:742)

at com.sap.engine.services.webservices.jaxrpc.wsdl2java.soapbinding.MimeHttpBinding.call(MimeHttpBinding.java:1240)

at proxy2.ConfigBindingStub.setCustomerMasterRFC(ConfigBindingStub.java:80)

at proxy2.ConfigBindingStub.setCustomerMasterRFC(ConfigBindingStub.java:111)

at proxy2.TestDealerClient.main(TestDealerClient.java:26)

This code works fine if i run it as a standalone java class by adding a main method...

Please let me know the solution asap...i

have a critical requirement for my client..

Thanks in advance..

I have send you some screenprints of

debug screens

[Former Member]

I am sending you the log file in an

attached zip ... please check and let me know your response

[former_member182372]

I don`t see any stacktrace in the file you sent me.

You have to set the breakpoint in line where e.printStackTrace(); is located (on web service). Do you know how to debug the server components?

[Former Member]

Hi

I the catch block i had e.printstacktrace() thats it...

How can i view the logs of this web service where can i find it ... Even Breakpoint does not help here ..

It also throws same message...

[former_member182372]

Hi Tarun,

1) log you can find somwhere here C:\usr\sap\J2E\JC00\j2ee\cluster\server0\log\defaultTrace.trc (my local WAS installation)

2) what do you mean "Even Breakpoint does not help here .. "? You can set breakpoint on e.printStacktrace() and when execution flow will reach this breakpoint you can select varialbe "e" in "Variables" view and see all details. At least what kind of error do you have.

Hi Maksim

Well that error is gone maksim but it just

throws that message it belive , It still doen't

connects to the SAP from web service...

I can explain the steps i did to create

and deploy web service...

I created a simpple java project in NWDS with a

class EclipseService.java in it.

Added the sapjco.jar in the project properties

to avoid compilation error.

Switch to web services perspective and

created a web service with the endpoint as the EclipseService class and exposing the method setEclipseData.

Build an EAR using the mouse click option in

WS persptve

Deployed EAR onto J2EE engine from same menu.

Obviously this EAR doe not have sapjco.jar in it.

After deploying my web service comes into the folowing folder with the directory structure as shown below

C:\usr\sap\J2E\JC00\j2ee\cluster\server0\apps\sap.com\EclipseService

So -- EclipseService

|_ servlet_jsp

|_EclipseService\Config\root\web-inf\

" " work

|_ webservices_container

( descriptors)

jars

wsdl

For your better understanding I have

send you the screenprints to your email address..

Please let me know if i am missing any

jar or anything has to be added there ....

[former_member182372]

Hi Tarun,

What is the Throwable you caugth? Can you set breakpoint or check log for stackTrace()?

Best regards, Maksim Rashchynski.

Hi Maksim

This is the code it cannot be simpler than this

import java.util.ArrayList;

import java.util.Properties;

import com.sap.mw.jco.IRepository;

import com.sap.mw.jco.JCO;

public class EclipseService {

public String setEclipseData(String test){

String returnStr="Default";

String SAP_CLIENT = "130";

String USER_ID = "username";

String PASSWORD = "password";

String LANGUAGE = "EN";

String HOST_NAME = "161.145.174.12";

String SYSTEM_NUMBER = "00";

JCO.Client aConnection=null;

IRepository aRepository=null;

try {

returnStr="Creating a client";

aConnection=JCO.createClient( SAP_CLIENT, USER_ID, PASSWORD, LANGUAGE, HOST_NAME, SYSTEM_NUMBER);

ArrayList array=new ArrayList();

array.add("Tarun");

array.add("Abhay");

array.add("Sujit");

array.add("Sandy");

array.add("Sachin");

returnStr=array.get(2).toString()"--"test;

}

catch(Exception e)

{

e.printStackTrace();

}

return returnStr;

}

}

Now if i comment the JCO code it works fine

and otherwise it throws that SOAP fault

exception...

Environment that i am using is

NWDS or Eclipse

SDM

SAP J2EE Engine Version 6.4

Pleaaaaaaaaaase help me out ....

Thanks in advance

[former_member182372]

Replace

catch(Exception e)
{ 
e.printStackTrace();
}

with

catch(Throwable e)
{ 
e.printStackTrace();
}

Hi

I tried by putting all the JAR files

mentioned in the above post but it didn't work .

still it is throwing the same exception.

I added them in the project proreties folder.

I opened the EAR file which gets generated from

NWDS..it doesn't conatin those jars...

Now this EAR is the one that is deployed on

SAP J2EE Engine and from where it will pick

those jar files when it is deployed in the SAP

J2EE engine...

Has anyone encountered such problem anytime...

Please Please help me out !!!

I will give him full points who can resolve

this issue....

Or let me know some alternative

I repeat the requirement :-

I have to create a JAVA webservice which

should have JCO code in it , the role of this

JCO code will be to pass some data to SAP RFCs

Let me know pleaseeeeeeeeee !!!!

Hi Tarun,

Wrap the code of yor webservices to try-catch block and analyze (log to file) errors before returning on server side. You will find the error in log or by debugging then.

Best regards, Maksim Rashchynski.

Hi,

Check whether you have added the following jars in the application's build path:

jaxrpc-api.jar

tc_sec_compat.jar

tc_sec_destinations_interface.jar

tc_sec_destinations_service.jar

tc_sec_https.jar,tc_sec_jaas.jar

tc_sec_saml_util.jar

tc_sec_ssf.jar

tc_sec_userstore_lib.jar

webservices_api.jar

webservices_lib.jar

sapxmltoolkit.jar

If not, add them first. Then also do the following:

Right click Project->Properties->Web Dynpro References

1. add tc_secdestinations~interface in the Interface Reference

2. add tc_secdestinations~service in the Service Reference

Hope this will work out.

Hi Tarun,

Call getCause() for caught exception and analyse com.sap.mw.jco.JCO.Exception. You will get information what`s wrong with JCo call.
