Hi All,
I am running my batch application in jboss 4.2.2. I am getting the below exception frequently though not every time i run the batch job. I am using spring 2.5.4 and spring-batch 1.0.1. My database is Mysql 5.1.23.
org.springframework.jdbc.UncategorizedSQLException : PreparedStatementCallback; uncategorized SQLException for SQL [SELECT COUNT(*) FROM BATCH_JOB_EXECUTION WHERE JOB_EXECUTION_ID = ?]; SQL state [null]; error code [0]; Connection handle is not currently associated with a ManagedConnection; nested exception is java.sql.SQLException: Connection handle is not currently associated with a ManagedConnection
I am using HibernateTransactionManager (Hibernate 3.2) in my application.
This is my mysql-ds.xml
<local-tx-datasource>
<jndi-name>DarkDS</jndi-name>
<connection-url>jdbc:mysql://10.52.91.72/dh_r5</connection-url>

Do i need to change something in my ds.xml ? I checked the jboss documentation but i couldn't find any info on this issue
Any fixes?
Please let me know if you need more information from me. I badly need a fix for this.
thanks in advance,
Ram
