I wanted to change the default h2 database to MS SQL Server therefore I followed all instructions from Bonita to configure SQL Server. But when I try to run start-bonita.bat I get the following error:
15:26:31,113 WARN [org.jboss.jca.core.connectionmanager.pool.strategy.OnePool] (JCA PoolFiller) IJ000610: Unable to fill pool: java:jboss/datasources/bonitaDS: javax.resource.ResourceException: IJ031084: Unable to create connection at org.jboss.jca.adapters.jdbc.xa.XAManagedConnectionFactory.getXAManagedConnection(XAManagedConnectionFactory.java:509) at org.jboss.jca.adapters.jdbc.xa.XAManagedConnectionFactory.createManagedConnection(XAManagedConnectionFactory.java:416) at org.jboss.jca.core.connectionmanager.pool.mcp.SemaphoreConcurrentLinkedDequeManagedConnectionPool.createConnectionEventListener(SemaphoreConcurrentLinkedDequeManagedConnectionPool.java:1320) at org.jboss.jca.core.connectionmanager.pool.mcp.SemaphoreConcurrentLinkedDequeManagedConnectionPool.fillTo(SemaphoreConcurrentLinkedDequeManagedConnectionPool.java:1136)

I will really appreciate if somebody can help me to get this problem solved.
Thanks in advance
