Hello everyone, I'm trying to use Guvnor repository with mysql. I'm using JBoss7. I configured the datasource as jndi resource like this: <datasource jta="true" jndi-name="java:jboss/datasources/guvnor" pool-name="guvnor" enabled="true" use-java-context="true" use-ccm="true"> <connection-url>jdbc:mysql://localhost:3306/guvnor</connection-url> <driver>com.mysql</driver> <transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation> <pool> <min-pool-size>10</min-pool-size> <max-pool-size>100</max-pool-size> <prefill>true</prefill> </pool> <security> <user-name>root</user-name> <password>password</password> </security> <statement> <prepared-statement-cache-size>32</prepared-statement-cache-size> <share-prepared-statements>true</share-prepared-statements> </statement> </datasource> Now, when I run guvnor I get this exception: Caused by: java.sql.SQLException: You cannot set autocommit during a managed transaction! at org.jboss.jca.adapters.jdbc.BaseWrapperManagedConnection.setJdbcAutoCommit(BaseWrapperManagedConnection.java:888) at org.jboss.jca.adapters.jdbc.WrappedConnection.setAutoCommit(WrappedConnection.java:715) at org.apache.jackrabbit.core.util.db.ConnectionHelper.getConnection(ConnectionHelper.java:395) [jackrabbit-core-2.2.8.jar:2.2.8] at org.apache.jackrabbit.core.util.db.ConnectionHelper.reallyExec(ConnectionHelper.java:351) [jackrabbit-core-2.2.8.jar:2.2.8] at org.apache.jackrabbit.core.util.db.ConnectionHelper$3.call(ConnectionHelper.java:339) [jackrabbit-core-2.2.8.jar:2.2.8] I think is related to the <transaction-isolation> tag. Any help? I couldn't find any example of how to configure this. Without using JNDI it works.
