Hi,
I am facing a strange problem to deploy my application in jboss-4.2.1.GA server.
When I start the server it will be expected to connect to the Data source in SQL server
2000.
But It throws following exceptions.
15:31:17,412 INFO [STDOUT] 15:31:17,287 ERROR [[/uc]] StandardWrapper.Throwable
java.lang.ExceptionInInitializerError

Basically I got the exception when I want to connect to the Data source in my code.
To configure Data Source of SQL server 2000 with JBOSS 4.2.1.GA i follow the following
steps.
1) In the web.xml File I add the following code.
<resource-ref>
| <description>DB Connection</description>
| <res-ref-name>MSSQLDS</res-ref-name>
| <res-type>javax.sql.DataSource</res-type>
| <res-auth>Container</res-auth>
| </resource-ref>
2) In the jboss-web.xml file entries are
<resource-ref>
| <res-ref-name>MSSQLDS</res-ref-name>
| <jndi-name>java:MSSQLDS</jndi-name>
| </resource-ref>
3) My JNDI Look up name of the Data source in the java code is
appDataSource=java:/MSSQLDS
Now I modified some of the files in the App server also.They are listed below.
1) In the C:\jboss-4.2.1.GA\jboss-4.2.1.GA\server\default\deploy folder
I update the mssql-ds.xml file with the following modifications.

|
|
| <!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional)
-->
|
| <type-mapping>MS SQLSERVER2000</type-mapping>
|
| </local-tx-datasource>
|
|
2)In the C:\jboss-4.2.1.GA\jboss-4.2.1.GA\server\default\conf folder I modified following
Files. They are Listed Below.
A)
login-config.xml
<application-policy name = "MSSQLDbRealm">
| <authentication>
| <login-module code =
"org.jboss.resource.security.ConfiguredIdentityLoginModule"
| flag = "required">
| <module-option name =
"principal">sa</module-option>
| <module-option name =
"userName">sa</module-option>
| <module-option name =
"password">admin</module-option>
| <module-option name =
"managedConnectionFactoryName">jboss.jca:service=LocalTxCM,name=MSSQLDS</module-option>
| </login-module>
| </authentication>
| </application-policy>
B)
standardjaws.xml
<jaws>
| <datasource>java:/MSSQLDS</datasource>
| <type-mapping>MS SQLSERVER2000</type-mapping>
| <debug>false</debug>
|
| ....
| ....
| </jaws>
C)
standardjbosscmp-jdbc.xml
<jbosscmp-jdbc>
|
| <defaults>
|
| <!--datasource>java:/DefaultDS</datasource-->
| <datasource>java:/MSSQLDS</datasource>
| <datasource-mapping>MS SQLSERVER2000</datasource-mapping>
|
| .....
| ......
|
|
|
3) I also put all the necessary drivers in the appropriate locations as it is needed to
create connection to the Data source.
Driver locations : C:\jboss-4.2.1.GA\jboss-4.2.1.GA\server\default\lib
|
| msbase.jar,mssqlserver.jar,msutil.jar.
================================================
Now I got the exception when I basically deploying the war file(by start the app server)
Though I am able to connect to the Data base with Normal java-JDBC program with the same
drivers.
==============================================
In the http://localhost:8080/jmx-console/ in the service=JNDIView
|
| I observe following things.
|
| MSSQLDS
| org.jboss.resource.adapter.jdbc.WrapperDataSource
|
| MSSQLDS
| java:MSSQLDS
| javax.naming.LinkRef
|
| when I "Invoke Output JNDI info in XML format" button.
==============================================
when I start the server with all these above mentioned configuration i got the following
Exception.

The lookup code for data source is like below
public DataSource getApplicationDataSource() {
try {
| Hashtable env = new Hashtable();
|
| env.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
| env.put(Context.PROVIDER_URL, "jnp://localhost:1099");
| Context context = new InitialContext(env);
|
| dataSource = (DataSource) context.lookup("java:/MSSQLDS");
|
|
| } catch ( NamingException ex) {
| ex.printStackTrace();
| }
|
| return dataSource;
| }
Sample of the Calling Code.
DataSource ds = this.getApplicationDataSource();
| con = ds.getConnection();
| if(con!=null){
| dm = con.getMetaData();
| System.out.println("Driver Information");
| System.out.println("\tDriver Name: "+
dm.getDriverName());
===============================================
Even If I try to use this Data source from a Stadalone Java program i got the
javax.naming.NameNotFoundException: MSSQLDS not bound

| at org.jnp.server.NamingServer.getBinding(NamingServer.java:537)

Please help me ...
