Connecting with database using setproperty over SOAP connection

Question

The following method connects to a MySQL database.
public void setDBDriverName(String in)
     dbDriverName = in;
public void setDBConnection(String in)
     dbConnection = in;
public void connectToMySQLDatabase() throws SQLException
     if(dbCon == null)
             try
                Class.forName(dbDriverName);     // SQL driver
                dbCon = DriverManager.getConnection(dbConnection);           // JDBC url
                s = dbCon.createStatement();
                   catch (Exception e)
                System.out.println("Could not connect to database using " + dbConnection + " at " + dbDriverName + " : " + e.getMessage());
     else
            System.out.println("Could not connect to databse : Already connected");
}The method is part of a webservice, in which I use setproperties to set the database connection because the webservice must work with different types of databases like Oracle and MySQL.
<jsp:useBean id="ContactHistorieClassid" scope="request" class="proxy.soap.ContactHistorieClassProxy" />
     <jsp:setProperty name="ContactHistorieClassid" property="DBConnection" value="org.gjt.mm.mysql.Driver" />
     <jsp:setProperty name="ContactHistorieClassid" property="DBDriverName" value="jdbc:mysql://localhost/contacthistorie" />
     <jsp:setProperty name="ContactHistorieClassid" property="clientID" value="1" />
<%
     ContactHistorieClassid.connectToMySQLDatabase();
%>What am I doing wrong here?

Answer 1

Forgot what happens, sorry. After trying to use the ContactHistorieClassid.connectToMySQLDatabase() method, my server console tells me that it cannot connect to the database, even though it returns the values as they were set in the setproperty.
When I manually enter the values like this...
Class.forName("org.gjt.mm.mysql.Driver");     // SQL driver                
dbCon = DriverManager.getConnection("jdbc:mysql://localhost/contacthistorie"); .. it works properly. So the setproperties are executed as the should be.
