IDoc Exception (4) Unsupported Operation from NW EP 7.0 ehp1 to ECC 6

[Former Member]

Hi fellow coders

I'm trying to send an IDoc (WPUWBW01) that I make in Java on an SAP NW EP 7.0 ehp1 SPS5 to an ECC 6.0 ehp4 SPS5.

I'm using the jar-files: jrfc.jar (external) and sapidoc70.jar (included in the PAR-file).

It works to request a transaction ID

//com.sap.mw.jco.JCO.Client.createTID()
String tid = client.createTID();

But when I try to send the IDoc (after I've done a "doc.checkSyntax()") with the send command:

//void com.sap.mw.jco.JCO.Client.send(Object arg0, String arg1)
//com.sap.mw.idoc.IDoc.Document
client.send(doc, tid);

I get the following exception:

com.sap.mw.idoc.IDoc$Exception: (4) IDOC_ERROR_UNSUPPORTED_OPERATION: Usage of SAP Java Connector IDoc Class Library is not supported in current environment.

As you can see it's not a JCo-exception but an IDoc exception, that makes me puzzled.

Some of the options are:

1. A port needs to be opened on ECC?

2. An RFC source/destination port needs to be created? In transaction SM59/SICF/WE21?

3. A module or the like needs to be activated in the ECC?

Any pointers in the right direction will be rewarded.

Thank you

Has this type of Java -> IDoc communication without the JCo connector for third parties never been done before?

Any tips will be appreciated.
