MSSQL with Jboss - sql-server

Question

I am trying to configure MSSQL with Jboss. I am getting exception where it says
"JDBC Unable to get managed connection"
I have put the sqljdbc_auth.dll and sqljdbc_xa.dl in the jboss\server\lib
Below is the config I have given in the mssql-ds.xml
<datasources>
<xa-datasource>
<!-- JNDI name of the DataSource, to be prefixed with "java:/" upon reference -->
<!-- DataSource are not available outside the virtual machine -->
<jndi-name>jdbc/ds/mssqlDS</jndi-name>
<!-- uncomment to enable interleaving <interleaving/> -->
<isSameRM-override-value>false</isSameRM-override-value>
<!-- Database connection settings -->
<!--<xa-datasource-class>com.microsoft.sqlserver.jdbc.SQLServerXADataSource</xa-datasource-class>
<xa-datasource-property name="URL">jdbc:sqlserver://ip:1433;databaseName=dev_sql</xa-datasource-property>-->
<!-- Alternate way of configuration -->
<xa-datasource-property name="ServerName">com.microsoft.sqlserver.jdbc.SQLServerXADataSource</xa-datasource-property>
<xa-datasource-property name="DatabaseName">dev_sql</xa-datasource-property>
<xa-datasource-property name="User">sa</xa-datasource-property>
<xa-datasource-property name="Password">sql!23</xa-datasource-property>
<xa-datasource-property name="SelectMethod">cursor</xa-datasource-property>
<!-- Uses the pingDatabase method to check a connection is still valid before handing it out from the pool org.jboss.resource.adapter.jdbc.ValidConnectionChecker -->
<valid-connection-checker-class-name>org.jboss.jca.adapters.jdbc.extensions.mssql.MSSQLValidConnectionChecker</valid-connection-checker-class-name>
<!-- Checks the SQL Server error codes and messages for fatal errors -->
<exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.SybaseExceptionSorter</exception-sorter-class-name>
<!-- XA datasource cannot reuse a connection outside a transaction once enlisted in a global transaction and vice-versa -->
<no-tx-separate-pools/>
<!-- Sets the default date format for the session
<new-connection-sql>alter session set nls_date_format='FXDD-MON-YYYY' optimizer_mode='ALL_ROWS'</new-connection-sql>
-->
<!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) -->
<metadata>
<type-mapping>MS SQLSERVER2000</type-mapping>
</metadata>
<!-- Database connection pooling settings -->
<min-pool-size>10</min-pool-size>
<max-pool-size>120</max-pool-size>
<idle-timeout-minutes>15</idle-timeout-minutes>
</xa-datasource>
</datasources>
I tried using tx with the below config
<datasources>
<local-tx-datasource>
<jndi-name>jdbc/ds/sqlDS</jndi-name>
<connection-url>jdbc:sqlserver://ip:1433;databaseName=dev_sql</connection-url>
<driver-class>com.microsoft.jdbc.sqlserver.SQLServerDriver</driver-class>
<user-name>sa</user-name>
<password>sql!23</password>
</local-tx-datasource>
</datasources>
Any leads ?
