Yes. Developing this will be a three-step process. First you will need to create a remote-enabled function call (RFC) module that encapsulates the request/response data that you need to make available via Web service.

Next you will need to build a Java Web service using SAP's Java JCo connector that receives incoming HTTP Web service requests. Finally, you will have to translate that data into a JCo function call that invokes the RFC that you have deployed in your R/3 application server.

Check out my articles on the JCo connector Java/SAP Development. You can also find a full sample application in my book Enterprise Java for SAP.
