Java Stack not installed during SAP installation ECC 6.0

[Former Member]

Dear Experts,

We are facing one peculiar issue with our client. The requirement is, our client is using SAP 6.0 in addition to that they are using one JAVA software also for calculating shipment costs. For business process, some SAP data needs to be transfered from SAP to Java and after some business processing in JAVA system again the details needs to be transfered to SAP.

For this requirement we proposed to use the IDOC process to transfer the data between SAP and Java using interface "SAP Java Connector (JCo). We planned to install SAP JCo in the JAVA Server and thought that the IDOC transfer process will work without any issue. Related to this if anybody has any value added suggestion please let us know.

Now the challenge we are facing is, our client already installed the SAP ECC 6.0 without JAVA STACK (Only with ABAP STACK).

Now my beloved question is,

1. in this case whether IDOC transfer between SAP to JAVA (&Viceversa) will happen between this two different systems without any issue..?

2. or we need to install JAVA STACK mandatorilly..?.

3. Other than SAP Java Connector is there any other solution is available to make the interface b/w SAP Vs JAVA (forced to use IDOC Only)..??

Thanks in advance

Dear Experts & John Wu,

Thanks for your feedback.

based on your feedback I understood that, both ABAB STACK and JAVA STACK is not required to install. Any one of the availability of the STACK is sufficient for making the interface between SAP ECC system and Java system. Whether my understanding is correct..?. Please confirm.

John Wu Question: - *you want to install sap java server and deploy your customer's java application there?*

No. We want to make a interface using "SAP JCO" between SAP ECC version and Java system to transfer the details between these two system. Using IDOC we need to transfer the data between these two systems.

the doubt we asked is, without JAVA STACK installation whether the data transfer between SAP ECC system and Java system will happen or not..?.

Another question is, in this case "SAP Java Connector" needs to be installed in which server..??. SAP ECC Server or in Java server..?. Currently both the systems are running in two different systems (2 different servers).

Kindly help us to understand the process better.

Thank you.

Warm Regards,

VEL

Hi,

you dont need to install a SAP WebAS Java.

You can use the SAP JCO Class Libraries in your Java Application.

your ecc is already there, you don't have to install any other server.

you just make some customization development using java connector.

connector should be installed in java server.

this may be a doc your technician can refer.

Hi,

You can also use web service's. If your java software has a web service exposed for performing the operations then according to me its the best way of doing it. Just you need to consume the webservice.

dual stack is not recommended now.

you want to install sap java server and deploy your customer's java application there?

you can use web service to enable the communication between java and ecc system.

if you have PI ready, you can get it to play here.
