by rockies
Hi,
I'm experiencing the errors below. Its an environment with 2 app servers. each app server is set as a separate cluster. The JVM is less than 1GB
Is there some internal limit that i need to change
Thanks
Dave

[JBoss Tools (users)] - How to configure Hibernate Console in a Maven project ?
by chawax
Hi,
I work on a Maven project with JPA Hibernate implementation for persistence. I would like to make Hibernate console work with this project, but I encounter problems.
My project has EJB3 entity classes (with JPA annotations) and this persistence.xml file (all in build path and so in classpath) :
<?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"
| xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
| http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
| version="1.0">
| <persistence-unit name="t4Seam">
| <provider>org.hibernate.ejb.HibernatePersistence</provider>
| <jta-data-source>java:/jdbc/t4Seam</jta-data-source>
| <properties>
| <property name="hibernate.hbm2ddl.auto" value="update"/>
| <property name="hibernate.show_sql" value="false"/>
| <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLInnoDBDialect"/>
| </properties>
| </persistence-unit>
| </persistence>
At runtime, database connection is configured with a datasource, so I added a hibernate.properties file to configure database connection for Hibernate console.
hibernate.connection.datasource=java:/jdbc/t4Seam
| hibernate.connection.driver_class=com.mysql.jdbc.Driver
| hibernate.connection.url=jdbc:mysql://localhost:3306/t4Seam
| hibernate.connection.username=T4
| hibernate.connection.password=T4
| hibernate.dialect=org.hibernate.dialect.MySQLInnoDBDialect
I then created my Hibernate Console configuration with "JPA" type, selected my hibernate.properties file, configured the persistence unit as "t4Seam" and added MySQL drivers in the classpath.
For what I understood, this is all I need to do since it looks for required files (EJB3 entities, persistence.xml) in the classpath. But when I jump to the Hibernate configuration view and double click on my configuration, I have the following stack trace :
Can't find mapping file

Which mapping file is it talking about ? It is JPA, so it doesn't need mapping files, doesn't it ? Is there something special to do to make it work with JPA ?
Thanks in advance for your help ;)
