Hi All, I'm attempting to connect to a PostgreSQL database via a database pool and seeing some odd behavior:
JBoss 4.0.5 c3p0-0.9.1-pre6.jar PostgreSQL 8.1 It looks to me that the pool is starting correctly, as I see it in the logs | 22:26:16,920 INFO [C3P0PooledDataSource] Bound C3P0 PooledDataSource to name 'java:EventDBPool'. Starting... | 22:26:16,951 INFO [PoolBackedDataSource] Initializing c3p0 pool... [EMAIL PROTECTED] ... | 22:26:16,993 INFO [JmxKernelAbstraction] installing MBean: persistence.units:ear=DataTier.ear,jar=DataTier.jar,unitName=EventDBUnit with dependencies: | 22:26:16,994 INFO [JmxKernelAbstraction] jboss.jca:name=EventDBPool,service=DataSourceBinding | However below I see: | --- MBeans waiting for other MBeans --- | ObjectName: persistence.units:ear=DataTier.ear,jar=DataTier.jar,unitName=EventDBUnit | State: NOTYETINSTALLED | I Depend On: | jboss.jca:name=EventDBPool,service=DataSourceBinding | | --- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM --- | ObjectName: jboss.jca:name=EventDBPool,service=DataSourceBinding | State: NOTYETINSTALLED | Depends On Me: | persistence.units:ear=DataTier.ear,jar=DataTier.jar,unitName=EventDBUnit | Here's my c3p0-service.xml: <?xml version="1.0" encoding="UTF-8"?> | <!DOCTYPE server PUBLIC "-//JBoss//DTD MBean Service 4.0//EN" "http://www.jboss.org/j2ee/dtd/jboss-service_4_0.dtd"> | <server> | <mbean code="com.mchange.v2.c3p0.mbean.C3P0PooledDataSource" name="jboss:service=EventDBPooledDS"> | <attribute name="JndiName">java:EventDBPool</attribute> | <attribute name="JdbcUrl">jdbc:postgresql://localhost/EventDB</attribute> | <attribute name="DriverClass">org.postgresql.Driver</attribute> | <attribute name="User">myuser</attribute> | <attribute name="Password">mypass</attribute> | <attribute name="IdleConnectionTestPeriod">90</attribute> | <attribute name="MaxPoolSize">15</attribute> | <attribute name="MinPoolSize">5</attribute> | <attribute name="TestConnectionOnCheckin">true</attribute> | | <depends>jboss:service=Naming</depends> | </mbean> | </server> | And my persistence.xml | <?xml version="1.0" encoding="UTF-8"?> | <persistence xmlns="http://java.sun.com/xml/ns/persistence" | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" | version="1.0"> | <persistence-unit name="EventDBUnit" transaction-type="JTA"> | <provider>org.hibernate.ejb.HibernatePersistence</provider> | <jta-data-source>java:EventDBPool</jta-data-source> | <properties> | <property name="hibernate.show_sql" value="true" /> | </properties> | </persistence-unit> | Also, if I create an EntityManagerFactory from that persistence unit directly in my code, I'm able to use it. However, if I use dependency injection via @PersistenceContext it doesn't work. My questions: 1) is there an error in my persistence.xml or c3p0-service.xml preventing startup or connection to the pool? 2) ought I to be using c3p0 still or JBoss's ManagedConnectionPool?
