Handling SAP deep structure via JCo

Question

Hello-
I have an RFC enabled function module in my ECC 6 system that I'd like to call using the JCo API's. I have read conflicting materials on whether this is even possible or not. Can anyone confirm if it is possible or not, and if you have a general description of how you handled it with the Java code it would be much appreciated. I am an experienced SAP developer who is delving into JCo for the first time.
Thanks,
Andy

Hi Andy
Here is the JCo API Javadocs: http://www.huihoo.org/openweb/jco_api/
Code could be like the following (I assume output table):
JCO.Client client;
/* code for ABAP connection and getting the client here*/
JCO.Repository myRepository = new JCO.Repository("Test", client);
JCO.IFunctionTemplate ft = myRepository.getFunctionTemplate(functionName);
JCO.Function function = ft.getFunction();
/* invoke function here */
JCO.Table jcoTable = function.getTableParameterList().getTable(tableName);
for (int i = 0; i < jcoTable.getNumRows(); i++) {
         jcoTable.setRow(i);
         // get value of the field <fieldName>: it could be anything:
         JCO.Table jcoTable = jcoTable.getTable(<field name>);
         // or JCO.Structure jcoTable = jcoTable.getStructure(<field name>);
         // or JCO.Field jcoField = jcoTable.getField(<field name>);
         // go ahead with the field: a) get plain value or b) iterate over its rows if it's a table again
// close the connection
