Do you have any hibernate related messages in any of your logs? And the one or two lines above/below NoClassDefFoundError?
Regards, David -----Original Message----- From: Joe Hertz [mailto:[EMAIL PROTECTED] Sent: Thursday, April 22, 2004 5:02 PM To: 'Struts Users Mailing List' Subject: RE: Hibernate 2.1.X and Struts 1.2 Unfortunately, not a bit :( It's not getting to the point of storing the SessionFactory in the JNDI tree or Servlet Context. It dies on construction of the SessionFactory. Ted's Plugin from the Struts-Hibernate example (still there as it turns out) avoids JNDI anyway. The current plugin listed on Hibernate.org *can* avoid it too, so I grabbed it and tweaked it to provide some of the same Session obtaining/releasing methods Ted's had. Both PlugIns behave identically for me. It will complain about hbm.xml errors if I have them, but once all solved, boom, NoClassDefFoundError It be nice if someone on the Hibernate.org forum chimed in. I'm going a bit nuts -- I'm getting closer to start questioning the contents of the Hibernate Distribution I downloaded since this was supposed to be a 2.1.1 issue. > -----Original Message----- > From: John McGrath [mailto:[EMAIL PROTECTED] > Sent: Thursday, April 22, 2004 4:46 PM > To: 'Struts Users Mailing List' > Subject: RE: Hibernate 2.1.X and Struts 1.2 > > > we wrote our own. we might be doing this back-assward, but > basically our first step is to put the factory we want into > the JNDI tree. with tomcat or resin, this is done in > server.xml or web.xml; in weblogic it's done with a startup > class (ours is ContentServiceFactoryStartup, it puts an > instance of our edu.whoi.cms.ContentServiceFactory into JNDI). > > then we have a class called edu.whoi.cms.ContentServiceFactoryPlugIn, > which implements org.apache.struts.action.PlugIn. it's most > important job is to put the Factory into the servlet context, > where it can be accessed by action classes. here's an excerpt: > > public void init( ActionServlet servlet, ModuleConfig config ) { ... > Context ctx = (Context) new InitialContext(); > ContentServiceFactory theFactory = > (ContentServiceFactory)ctx.lookup( > "ContentServiceFactory" ); > this.theServlet = servlet; > servletCxt.setAttribute("CONTENT_SERVICE_FACTORY", > theFactory); ... } > > > ContentServiceFactory has a method called getContentService, > this returns our content service interface (IContentService). > it's a little indirect, but if we ever decide to bail on > hibernate and use, say, iBatis, we would have to write an > iBatis implementation of IContentService, but none of our > other code would change. > > this all gets triggered at startup by this line in struts-config: > > <plug-in className="edu.whoi.cms.ContentServiceFactoryPlugIn" /> > > then with our action classes, we have a BaseAction class that > all other action classes inherit.
