Question

Hi,
I have a webservice and in the same server(weblogic 9.2) a data source(cgAppSource) is configured. the database control is not instanciating properly, it is always remains null despite the calling of webservice. I am getting NullPointerException in the webservice. First time I am using annotation to execute a SQL query. It is urgent.can anyone please help me. what code change I have to do in both the files.
SampleDatabaseControl.java -
package control;
import java.sql.SQLException;
import org.apache.beehive.controls.api.bean.ControlBean;
import org.apache.beehive.controls.system.jdbc.JdbcControl;
@org.apache.beehive.controls.api.bean.ControlExtension
@JdbcControl.ConnectionDataSource(jndiName="java:comp/env/jdbc/cgAppSource")
public interface SampleDatabaseControl extends JdbcControl ,ControlBean{
     static final long serialVersionUID = 1L;
@JdbcControl.SQL(statement="SELECT SYSDATE FROM DUAL")
public String returnSysDate() throws SQLException;
The webservice : ControlWebservice.java
package service;
import javax.jws.WebService;
import javax.jws.WebMethod;
import javax.jws.soap.SOAPBinding;
import weblogic.jws.WLHttpTransport;
import org.apache.beehive.controls.api.bean.Control;
import control.SampleDatabaseControl;
@WebService(name="ControlWebservicePortType", serviceName="ControlWebservice",
          targetNamespace="localhost")
@SOAPBinding(style=SOAPBinding.Style.DOCUMENT,
          use=SOAPBinding.Use.LITERAL,
          parameterStyle=SOAPBinding.ParameterStyle.WRAPPED)
@WLHttpTransport(contextPath="ControlWebserviceProj", serviceUri="ControlWebservice",
          portName="ControlWebservicePort")
public class ControlWebservice {
     @Control
     private SampleDatabaseControl SampleDatabaseControl;
     @WebMethod()
     public String returnDate()
          String returnValue = null;
          try{
               returnValue = "This message sent date :" + SampleDatabaseControl.returnSysDate(); // getting null pointer Exception here.
          catch(Exception e)
               e.printStackTrace();
          return returnValue;
}

Hi james,
In that link it says to 'Create a Beehive-enabled Server Domain' in which On the second page(named <strong>Select Domain Source</strong>), I need to place a check in the <strong>Apache Beehive</strong> checkbox . But in my machine when I follow the steps I dont find any such checkbox in the (named <strong>Select Domain Source</strong>) page. Is this the problem? I can see only two check boxes. The page looks like......
Generate a domain configured automatically to support the following product. // radio select
Weblogic Server (Required) //check box
Workshop for Weblogic Platform // check box
Base this domain on an existing domain. //radio select
Templatelocation .... // a browse option
Do I need to do some other configuration to make beehive check box active in the page? All the beehive jars are present in the instalation. And as far as I remember I did the full instalation of Weblogic 9.2 after downloading from the bea site. and I am giving the beehive related jar
<p>
beehive-controls.jar,beehive-jdbc-control.jar,weblogic-jdbc-control.jar in the lib folder wnder WEB-INF and deploying.
</p>
