*** DataSource Conn problem with MSSQLSERVER in JBOSS
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

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.
<datasources>
<local-tx-datasource>
<jndi-name>MSSQLDS</jndi-name>
<!--use-java-context>false</use-java-context-->
<connection-url>jdbc:microsoft:sqlserver://LAPTOPIB132;DatabaseName=rfid_ucprn</connection-url>
<!--connection-url>jdbc:microsoft:sqlserver://10.236.70.221:1433;DatabaseName=rfid_ucprn</connection-url-->
<driver-class>com.microsoft.jdbc.sqlserver.SQLServerDriver</driver-class>
<user-name>sa</user-name>
<password>admin</password>
<min-pool-size>5</min-pool-size>
<max-pool-size>20</max-pool-size>
<idle-timeout-minutes>10</idle-timeout-minutes>
<!-- sql to call when connection is created-->
<new-connection-sql>SELECT * FROM UserAuth</new-connection-sql>
<!-- sql to call on an existing pooled connection when it is obtained from pool-->
<check-valid-connection-sql>SELECT BRPName,BRPMcName,BRPServerPort,BRPRemotePort from BRP</check-valid-connection-sql>
<!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) -->
<metadata>
<type-mapping>MS SQLSERVER2000</type-mapping>
</metadata>
</local-tx-datasource>
</datasources>
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.
15:30:49,584 INFO [ConnectionFactoryBindingService] Bound ConnectionManager 'jboss.jca:service=ConnectionFactoryBinding,name=JmsXA' to JNDI name 'java:JmsXA'

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:529) at org.jnp.server.NamingServer.getBinding(NamingServer.java:537) at org.jnp.server.NamingServer.getObject(NamingServer.java:543)
Please help me ... /shankha
