Webservice in NWDS having JCO code

[Former Member]

Hi All,

I have a requirement which is to create a JAVA web service in NWDS which can service a .NET internet Application take some data from .NET and

put it into the SAP by calling a RFC Module...

I have written a class which has two methods

it simply connects to SAP & processes the RFC Module...

This class works fine if i run it as a

standalone java application with a main

method.. <b>but it fails</b> when i deploy it as a web service and try to run it through a Standalone

Client ... it is able to create the

WSDL and the methods are also visible but it

fails from the code where JCO logic starts...

I am getting the error message as

<b>Warning ! Protocol Implementation [com.sap.engine.services.webservices.jaxrpc.

wsdl2java.features.builtin.MessageIdProtocol] could not be loaded (NoClassDefFoundError) !

Error Message is :com/sap/guid/GUIDGeneratorFactory

I am using sapjco.jar in the project properties dialog box but it is not there when the EAR is generated & deployed..

Can this be a problem ??? If yes where should i put

this sapjco.jar

Please help me out as i am really facing a hard time finding out the reason for this

Hi Maksim,

Thankyou so much maksim for the jar file path

you had given , the first error is gone

when i put the jar file in project

properties.

But i am still getting some errors

because of the JCO library methods that

i am using ... all other simple web services

work fine in my system but i am getting

following errors

<b>javax.xml.rpc.soap.SOAPFaultException: com/sap/mw/jco/JCO

at com.sap.engine.services.webservices.jaxrpc.

wsdl2java.soapbinding.MimeHttpBinding.

at com.carrier.isa.Client.main(Client.java:29)</b>

when i put a simple code like

<b>JCO.Client aConnection=null;

IRepository aRepository=null;

try {

System.out.println("Creating a client");

aConnection=JCO.createClient(

SAP_CLIENT,

USER_ID,

PASSWORD,

LANGUAGE,

HOST_NAME,

SYSTEM_NUMBER);</b> System.out.println(aConnection.toString());

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;

}

the code above is just a snippet of the whole .

I have sapjco.jar in project properties in NWDS or eclipse but this jar is missing when

i build an EAR in the Web services perspective..

Can the missing of this jar in the

project EAR be the cause of problem ...

if yes let me know where should i add it ...

Also, I created a simple java project so i

am not having any WEB-INF folder ...

do i need to create a web project instead ..

Please help me as you did earlier ..

I would be highly obliged ....

Answer: <b>Simple Java Project will not have WEB-INF folder.

Web Project will sure have WEB-INF folder</b>

********************************

Are you missing any XML jar file ???

Check ?

The follwoing are some of the jar that i find in my NWDS:

boot.jar

iq-lib.jar

tc_sec_wssec_lib.jar

util.jar

webservice_api.jar

webservice_lib.jar

SapIdeWebServiceToolsSoap.jar

Try these !!!!

Thanks

Jack

You need to put the required jar files into the WEB-INF/lib directory of your war file, for run time execution.

Hi Tarun,

try to add <NWDS_INSTALL_FOLDER>/SAP/JDT/eclipse/plugins/com.sap.tc.ap/comp/SAP-JEE/DCs/sap.com/com.sap.guid/_comp/gen/default/public/default/lib/java/guidgenerator.jar to class path of your standalone proxy.

Best regards, Maksim Rashchynski.
