Can I use JCo to call a java program in another server?

[Former Member]

Hi, experts.

In XI, can I use JCo to call a java program in another server?

If yes, how to do this?

Does anybody have a example?

Hi Paulo !

By definition:

SAP’s new Java middleware, the SAP Java Connector (JCO) allows customers and partners to easily build SAP-enabled components in Java. JCO supports both inbound (Java calls ABAP) and outbound (ABAP calls Java) calls in desktop and server applications.

I have some ideas:

• create a JCO Server program that is called from an ABAP program (could be abap mapping or just an RFC called from XI)

• expose your java functionality as webservice and then call it using SOAP from XI.

Also check SAP Java Resource Adapter

Hi Paulo,

Below is the example for JCo lookup from XI server.

In the below example i am having a Internal table with name "MATNR" in the function Module.

V_Matnr and VStorage_Location are the fields in the Internal TBALE "MATNR".

where ---> tabMatnrUsed.setValue(Matnr, "V_MATNR");

matnr is the value passed as input to function module

JCO.Repository mRepository;

JCO.Client mConnection = JCO.createClient("<Client>", // SAP client

"<USERID>", // userid

"<PASSWORD>", // password

"<LNG>", // language

"<HOSTNAME>", // host name

"<SYSNO>"); // system number

try {

mConnection.connect();

} catch (Exception e) {

// e.printStackTrace();

}

mRepository = new JCO.Repository("SAPLookup", mConnection);

IFunctionTemplate ft =

mRepository.getFunctionTemplate("<FM NAME>");

JCO.Function function = ft.getFunction();

JCO.ParameterList allTables = function.getTableParameterList();

JCO.Table tabMatnrUsed = allTables.getTable("MATNR");

tabMatnrUsed.setValue(Matnr, "V_MATNR");

mConnection.execute(function);

allTables = function.getTableParameterList();

tabBnkUsed = allTables.getTable("tabMatnrUsed");

for (int i = 0; i < tabMatnrUsed.getNumRows(); i++) {

tabBnkUsed.setRow(i);

String storageLocation =

(String) tabBnkUsed.getValue("VStorage_Location");

}

mConnection.disconnect();

In this case i used the Internal Table "MATNR" for both input and output and

"MATNR" and "Storage_Location" are the fields

appreciate if helpful
