How to communicate with a SAP application from JAVA

we are planning to integrate our Sales and Distribution module to SAP application. We need to store the Sales information in a SAP application.

we are migrating the existing data using Exchange Infrastructure/ BDC of SAP to load sales module existing data.

Now our challenge is how to continuously interact with SAP from JAVA to store and retrieve data from the sales module?

Is there any tools available to communicate with SAP from java.

Thanks,

you have multiple options:

• use SAP Business Connector
• use SAP JCO to call SAP RFC Functions from java
• create SOAP Webservices in SAP and consume them from java

I really recommend the webservices way.
