Invalid character???

I'm at a total impasse. I have a stored function that returns a SYS_REFCURSOR. It works fine, I can call it in SQL*Plus and see the data that's been extracted. I'm trying to call it from Java:

       String spName;
       try 
       {
           getDBConnection();        /* sets "dbConnection */
        
           spName = "{ call ? := getReporterData(?) }";
                   
           sprocStmt = dbConnection.prepareCall(spName);
           sprocStmt.registerOutParameter(1, OracleTypes.CURSOR);
sprocStmt.setString(2, key);
           sprocStmt.execute();

And I get ORA-00911 Invalid character. What invalid character?
