I'm a complete newb so bear w/ me!

I'm unable to include hibernate w/ my web app(currently using struts). The error I get is :

HTTP Status 404 - Servlet action is not available

type Status report

message Servlet action is not available

description The requested resource (Servlet action is not available) is not available.

Apache Tomcat/5.0.12

I get this error when I fire up the web app. When I remove the "plugin" from my struts-config.xml, the web app works fine. Here is my hibernate-cfg.xml:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd">
<hibernate-configuration>
<!-- a SessionFactory instance listed as /jndi/name -->
<session-factory name="hibernate/sessionFactory">
<property name="connection.url">jdbc:mysql://172.16.0.5:3306/dlonline</property>
<property name="connection.username">testuser</property>
<property name="connection.password">password</property>
<property name="connection.driver_class">org.gjt.mm.mysql.Driver</property>
<property name="show_sql">false</property>
<property name="use_outer_join">true</property>

<!-- properties for this SessionFactory only -->
<property name="dialect">net.sf.hibernate.dialect.MySQLDialect</property>

<!-- mapping files -->
</session-factory>
</hibernate-configuration>


I added this to the plugin section of struts-config.xml

<plug-in className="edu.arbor.util.plugin.HibernatePlugIn">
<set-property property="configFilePath" value="/WEB-INF/hibernate.cfg.xml" />
<set-property property="storeInServletContext" value="true" />
</plug-in>

and I added the class HibernatePlugIn to my project and compiled per instructions at the website http://www.hibernate.org/105.html

What am I missing? I just added a new empty class file in my WEB-INF/classes directory and called it HibernatePlugIn. Is this the wrong place. Should I have done something else. Does anyone have any examples I can look at the DON'T use JNDI. If anyone would post any code or e-mail me some at meadmaker1977@yahoo.com.

Is that your actual hibernate.cfg.xml ?

If so, you don't seem to be really using hibernate at all cause youre not telling hibernate which classes you want to map to a db:

maybe you overlooked this part:
http://www.hibernate.org/hib_docs/refer ... uration-s6

And take a little more time to read this one to:

http://www.hibernate.org/hib_docs/refer ... lasses.htm

I understand that there needs to be mappings to actually use hibernate, but I can't even get started. Do you need mappings to insert hibernate as a plugin to struts? I would think that you wouldn't. I read the documents that you posted and I seem to be folowing them( as much as they relate to my web app). If you would like to send me working examples, I would appreciate it.

Read the Quickstart tutorial in the official examples sections of the wiki. It should at least get you started. http://www.hibernate.org/hib_docs/examples/.

The parse will fail when creating the session factory. You can add a mapping programmatically so I think the DTD is wrong. You can use an internal DTD that removes the mapping requirement to get around that but you still need a mapping to do anything useful.

I created a Struts/Hibernate application for some presentations. You can get to it on Sourceforge. It is a complete CRUD application. The example is part of the iseries-toolkit (www.iseries-toolkit.org). In CVS download the span module. There is also a release on the releases page but CVS is a little more current.

I should have given a link to the presentation that explains that code:

http://www.orlandojug.org/Struts-JUG.pdf

Looks like you don't have Struts configured correctly since "action" is usually the name of the Struts servlet that handles all *.do URLs. You may be getting an error on startup that is preventing the servlet from starting, you should check catalina.out, the host log (in $CATALINA_HOME/logs) and any other log you might be writing to and post the exception trace here.
