Hi,

I have been using hibernate for over a year now. Ihave developed an applicationusing Hibernate 3.0. I have deployed this application on Tomcat and left it there running. It worked fine till today (27th Septmeber 2006) afternoon. Basically it started giving me an exception as follows:

Caused by: org.hibernate.HibernateException: Could not parse configuration: /hib
ernate.cfg.xml

I could not understand the problem, and why it came out now!! I restarted tomcat several times, but still giave me the same exception. Thus I decided to compile the system again.

To my amazment neither on the development environment it wanted to work. It compiles fine, but when I run the web application it gave me the same EXACT exception.

I can not believe my eyes because untill this morning, the same application was working Just fine!!

I am connecting with Microsoft Sql Server 2000, but I also tried it with Microsoft Sql Server 2005 ... it did not work on both!!

Thanks for any replies.

          configuration.configure();
          
          // Create the session factory.
            sessionFactory = configuration.buildSessionFactory();
        } catch (Throwable ex) {

This is the wrong DTD.

So if it is wrong, why was it working and all of a sudden it is no longer working ... I did not change and library!

Please do not get me wrong, I will go and search and fix that out. I am only asking because I am a little confused on how all of a sudden that error came out.

Thank You for your help

I have updated the DocType. Tried running XDoclet for my classes, and Iget this error for each class that should be persisted.

Code:
XJavaDoc Ignoring class com.sixpmodel.cvmanager.Global in C:\Java\cvmgr\src\java\com\sixpmodel\cvmanager\Global.java. It was generated (Thu Jun 22 16:30:58 CEST 2006) after XJavaDoc's timestamp was reset (Wed Sep 28 09:26:33 CEST 2005)


I really can't understand these errors! Please give me something to read to solve these problems (I really can not understand why everything burst out all of a sudden :( )

I repeat .. all this code was working fine!!! Now I even tried to run an old version of my application using Hibernate and XDoclet. XDoclet gives me the same error mentioned above on all objects I have persistance on ... Thus I can not create a build to test!! ... I really can not understand how a peace of code that was not touched was previously working fine and now it is not! :( .. Please any help!? I am inclined to change all the code that needs changing if it means making the system work fine again! However do not know what needs changing .. I am thinking of going to annotaions!!

I am clueless on what happened and that is what is making me feel so bad about the whole issue!!

Regards,
bormli

would you double-check the presence of hibernate.cfg.xml?

Maybe your system did not have outgoing internet connectivity and was not downloading + validating the DTD. Somebody fixed the routing or DNS on the system (default gateway) or on the LAN and now it gets outgoing connectivity. Some validating XML parser is downloading the DTD and it's not happy...

Just a wild guess :)

So basically I have two problems.

Problem 1:
My application that was running on the server started to validate the dtd, I had a wrong dtd and thus it broke up!! (am I write?)

Problem 2:
XDoclet is no longer generating the *.hbm.xml for each my persisted objects and is giving me the error I mentioned in my previous post.

I can try to solve problem 1 by changing the dtd directly into my war file where I already have all the *.hbm.xml files in place!! .. not sure if this would work, but I will give it a try.

The second problem is stopping me from actually doing another build of my web application. I am seriously thinking to upgrade to hibernate version 3.2.0 Cr4 and use annotations .. does anyone think it is a bad idea?

Thanks for the info, at least, I am learning something from all this bad luck! :)

Regards and many thanks,
bormli

Trying to change the dtd in the WAR file still did not work out :( and all my *.hbm.xml files have the correct dtd reference .. that is a dtd for version 3.0!! However I get an exception telling me that tag hibernate-mapping needs to be closed with a '>'!! believe me, all tags are properly closed :(

What should I do?
