Hi,
While developing a web application on JBoss, I come to the following
issue at one point:
19:02:24,119 WARN [TxConnectionManager] Connection error occured:
[EMAIL PROTECTED]
[EMAIL PROTECTED]
handles=2 lastUse=1186592544082 permit=true trackByTx=true
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
txSync=null]
and then, no database related stuff works any longer on that page, and I
get errors like:
java.sql.SQLException: No operations allowed after connection closed.
org.jboss.util.NestedSQLException: Could not enlist in transaction on
entering meta-aware object!; - nested throwable:
(java.lang.IllegalStateException: Can't enlist - already a tx!); -
nested throwable: (org.jboss.resource.JBossResourceException: Could not
enlist in transaction on entering meta-aware object!; - nested
throwable: (java.lang.IllegalStateException: Can't enlist - already a tx!))
It seems like some connection dropped / lost issue. I'm using MySQL as a
backend. The DS configuration is fairly simple:
<local-tx-datasource>
<jndi-name>seeDataSource</jndi-name>
<connection-url>jdbc:mysql://localhost:3306/Foo</connection-url>
<driver-class>com.mysql.jdbc.Driver</driver-class>
<user-name>foo</user-name>
<password>bar</password>
<exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>
<metadata>
<type-mapping>mySQL</type-mapping>
</metadata>
</local-tx-datasource>
What could be wrong?
