<div class="jive-rendered-content"><p>Hi guys,</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I am using JBoss 4.0.2 (and am not in a position to upgrade) to run a Java+Hibernate+Struts+SQL Server 2008 application. Originally it was SQL Server 2005 for which I had a driver sqljdbc.jar, after a while a new server for 2008 was added so the driver was also updated to sqljdbc4.jar. Things worked perfectly for years, I could connect to both servers with the new driver without any problem, just the necessary changes in ds.xml. However for a couple of weeks JBoss get's blocked when using the newer driver whatever DB server I try to connect. Since then I have survived using the older driver and only connecting to the 2005 SQL server but I need access to the 2008 server also.</p><p>There are no errors in the logs, here's an excerpt:</p><table><tbody><tr><td style=";">19:48:09.798 INFO  [                    </td><td style=";">org.hibernate.util.NamingHelper] JNDI InitialContext properties:{}</td></tr></tbody></table><p>19:48:09.798 INFO  [  org.hibernate.connection.DatasourceConnectionProvider] Using datasource: java:comp/env/jdbc/t2br6</p><table><tbody><tr><td style=";">19:48:09.798 DEBUG [   </td><td style=";">org.jboss.resource.connectionmanager.IdleRemover] internalRegisterPool: registering pool with interval 900000 old interval: 9223372036854775807</td></tr><tr><td style=";">19:48:09.798 DEBUG [   </td><td style=";">org.jboss.resource.connectionmanager.IdleRemover] internalRegisterPool: about to notify thread: old next: 1321120539798, new next: 1321120539798</td></tr></tbody></table><p>19:48:09.798 DEBUG [org.jboss.resource.adapter.jdbc.local.LocalManagedConnectionFactory] Using properties: {user=****, password=--hidden--}</p><p>19:48:09.798 DEBUG [org.jboss.resource.adapter.jdbc.local.LocalManagedConnectionFactory] Checking driver for URL: jdbc:sqlserver://1.1.2.2:1433;DatabaseName=ABC</p><p>19:48:09.798 DEBUG [org.jboss.resource.adapter.jdbc.local.LocalManagedConnectionFactory] Driver already registered for url: jdbc:sqlserver://1.1.2.2:1433;DatabaseName=ABC</p><table><tbody><tr><td style=";">19:55:39.785 DEBUG [   </td><td style=";">org.jboss.resource.connectionmanager.IdleRemover] run: IdleRemover notifying pools, interval: 450000</td></tr><tr><td style=";">20:03:09.742 DEBUG [   </td><td style=";">org.jboss.resource.connectionmanager.IdleRemover] run: IdleRemover notifying pools, interval: 450000</td></tr></tbody></table><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>It just doesn't do anything after the message "Driver already registered". </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The datasource file looks like this:</p><p><datasources></p><p>  <local-tx-datasource></p><p>    <jndi-name>t2br6</jndi-name></p><p>    <connection-url>jdbc:sqlserver://1.1.2.1:1433;DatabaseName=ABC</connection-url></p><p>    <driver-class>com.microsoft.sqlserver.jdbc.SQLServerDriver</driver-class></p><p>    <user-name>ABC</user-name></p><p>    <password>***</password></p><p>    <min-pool-size>3</min-pool-size></p><p>    <max-pool-size>10</max-pool-size></p><p>    <blocking-timeout-millis>30000</blocking-timeout-millis></p><p>    <idle-timeout-minutes>15</idle-timeout-minutes></p><p>    <prepared-statement-cache-size>1000</prepared-statement-cache-size></p><p>    <set-tx-query-timeout/></p><p>    <query-timeout>300</query-timeout></p><p>    <new-connection-sql>SET ANSI_WARNINGS OFF;SET LOCK_TIMEOUT 60000;SET CONCAT_NULL_YIELDS_NULL OFF;</new-connection-sql></p><p>    <check-valid-connection-sql>SELECT 'check valid cnn hib'</check-valid-connection-sql> </p><p>    <track-statements>false</track-statements>     </p><p></local-tx-datasource></p><p>  <no-tx-datasource></p><p>    <jndi-name>t2br6_plain_jdbc</jndi-name></p><p>    <connection-url>jdbc:sqlserver://1.1.2.2:1433;DatabaseName=ABC</connection-url></p><p>    <driver-class>com.microsoft.sqlserver.jdbc.SQLServerDriver</driver-class></p><p>    <user-name>ABC</user-name></p><p>    <password>***</password></p><p>    <min-pool-size>3</min-pool-size></p><p>    <max-pool-size>10</max-pool-size></p><p>    <blocking-timeout-millis>30000</blocking-timeout-millis></p><p>    <idle-timeout-minutes>15</idle-timeout-minutes></p><p>    <prepared-statement-cache-size>1000</prepared-statement-cache-size></p><p>    <set-tx-query-timeout/></p><p>    <query-timeout>300</query-timeout></p><p>    <new-connection-sql>SET ANSI_WARNINGS OFF;SET LOCK_TIMEOUT 60000;SET CONCAT_NULL_YIELDS_NULL OFF;</new-connection-sql></p><p>    <check-valid-connection-sql>SELECT 'check valid cnn jdbc'</check-valid-connection-sql> </p><p>    <track-statements>false</track-statements>     </p><p>  </no-tx-datasource></p><p></datasources>.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Since the problem appeared I have a new computer, fresh jboss installation, fresh Eclipse installation, new everything (except maybe the same internal IP).
