Re: [Resin-interest] PermGen problems installing Confluence
How have you increased the MaxPermGen of your resin install? Just ot make sure you have not increased the size of the watchdog instead of the real instance, which happened to me at the beginning :). Confluence has so many JSPs and other internal classes that it needs quite a chunk of memory for that. The node where we are running a JIRA Confluence instance has these settings inside resin.xml (Resin 3.1.5 and Confluence 2.8.1 though): jvm-arg-server/jvm-arg jvm-arg-XX:PermSize=128m/jvm-arg jvm-arg-XX:MaxPermSize=192m/jvm-arg jvm-arg-Xmx512m/jvm-arg jvm-arg-Xms512m/jvm-arg jvm-arg-Xss1m/jvm-arg jvm-arg-Djavax.xml.parsers.DocumentBuilderFactory=org.apache.xerces.jaxp.DocumentBuilderFactoryImpl/jvm-arg jvm-arg-Djavax.xml.parsers.SAXParserFactory=org.apache.xerces.jaxp.SAXParserFactoryImpl/jvm-arg S!

Re: [Resin-interest] Hibernate transactions
Not a version issue. An entitymanager should not get transaction by itself. Transaction in a modern java appserver should be XA or JTA transaciton. An entitymanager will detect if there is a JTA transaction existing and will join it if there is an open one. You need to use an injected UserTransaction instance to do the transaction stuff and leave the entitymanager do db stuff and the entitymanager will participate in the transaction. -Wesley 2010/3/29 Stargazer starga...@blueyonder.co.uk On 27-Mar-2010 01:10, Stargazer wrote: Resin 4.0.5 - following http://wiki.caucho.com/Hibernate works fine, but I'd like to take it to the next level and persist something.

Also, if you absolutely need to use the EntityTransaction, you'd need to
grab the EntityManagerFactory, not the EntityManager. The EntityManager
is tied into the container's transaction manager.
The UserTransaction is registered with CanDI, by the way, so it's easy
to grab:
public class MyBean {
@Inject UserTransaction _ut;
...
}

Re: [Resin-interest] PermGen problems installing Confluence
But you just said you're running it using 192m. Did I miss something? I only have Confluence (so far), and a handful of other webapps.

Ok thanks, I'm now sure the problem was me working from old Hibernate
docs. But I'm still struggling.
Referring back to the example: http://wiki.caucho.com/Hibernate
http://wiki.caucho.com/HibernateIt works perfectly as given, with
resin 4.0.5. I added the UserTransaction and tried to make a change and
commit but saw no difference in the db. Since the courses were listed
I'm assuming everyting else is ok. What have I missed please? Heres the
servlet in full:
package example;
import java.io.IOException;
import java.io.PrintWriter;
import javax.inject.Inject;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.transaction.UserTransaction;
public class CourseServlet extends HttpServlet
{
// Resin IoC will inject this
@PersistenceContext(unitName=example)
private EntityManager _manager;
@Inject
private UserTransaction ut;
public void service(HttpServletRequest request, HttpServletResponse
response)
throws IOException, ServletException
{
PrintWriter out = response.getWriter();
response.setContentType(text/html);
out.println(EntityManager = + _manager + br/);
CourseBean []course = new CourseBean[2];
course[0] = _manager.find(CourseBean.class, new Integer(1));
course[1] = _manager.find(CourseBean.class, new Integer(2));
out.println(Course Detailsbr/br/);
for (int i = 0; i course.length; i++) {
out.println(course: + course[i].getCourse() + br/);
out.println(teacher: + course[i].getTeacher() + br/);
}
CourseBean updateCourse = _manager.find(CourseBean.class, new
Integer(1));
try {
ut.begin();
updateCourse.setCourse(Magic);
ut.commit();
} catch (Exception e) {
e.printStackTrace();
}
}
}
