Trying to connect to R/3

Former Member

Hi all,

I am trying to connect to R/3 and call an RFC.

I have included the following line of code :-

IConnectorGatewayService cgservice = PortalRuntime.getRuntimeResources().getService(IConnectorGatewayService);

But it gives a compilation error saying "IConnectorGatewayService cannot be resolved".

Can some one tell me what is the right PAR file which i need to include in my build path to avoid this problem.

It will be really helpful if some one can give me any example showing how we connect to R/3 and call an RFC.

Thanks in advance.

Regards,

Narahari

Hi Narahari,

You need to include the jar file called

com.sap.portal.ivs.connectorserviceapi.jar

Here is some example code which explains the steps you need to take to connect to R/3 and execute a BAPI or RFC:

//1. get connector gateway service

IConnectorGatewayService cgs=PortalRuntime.getRuntimeResources.getService(IConnectorGatewayService.KEY);

//2. get a connection

IConnection conn=cgs.getConnection("SAP",request);

//or

ConnectionProperties cp=new ConnectionProperties(request.getLocale(),request.getUser());

IConnection conn=cgs.getConnection("SAP",cp);

//3. get interaction

IInteraction ix=conn.getInteractionEx();

//4. get ineractionspec;

IInteractionSpec ixspec=ix.getInteractionSpec();

ixspec.setPropertyValue("NAME","BAPI..");

//5. fill input parameters

//input field

RecordFactory rf=ix.getRecordFactory();

MappedRecord input=rf.createMappedRecord("input");

input.put("INPUT_FIELD",value);

//input structure

IFunction function=conn.getFunctionsMetaData().getFunction("BAPI..");

IStructureFactory sf=ix.retrieveStructureFactory();

IRecord structure=(IRecord) sf.getStructure(function.getParameter("INPUT_STRUCTURE").getStructure());

structure.setString("veld1", value1);

structure.setString("veld2",value2);

input.put("INPUT_STRUCTURE",structure);

//input table

IFunction function=conn.getFunctionsMetaData().getFunction("RFC..");

IStructureFactory sf=ix.retrieveStructureFactory();

IRecordSet table=(IRecordSet) sf.getStructure(function.getParameter("INPUT_TABLE").getStructure());

table.insertRow();

table.setString("veld1",value1_1);

table.setString("veld2",value1_2);

table.insertRow();

table.setString("veld1",value2_2);

...

input.put("INPUT_TABLE",table);

//6. execute function

MappedRecord output=(MappedRecord) ix.execute(ixspec, input);

//7. retrieve results

Object result=output.get("outputtable");

//8. cast result to appropriate type, for instance IRecordSet, and use the contents in your application

Johan

Hi,

Thank you for ur response.

Could you please show me how to handle the result also(using RecordMetaDeta etc.) including handling internal table ouput and also normal values(coming from R/3)??

This will of great help for me.
