Welcome to the Ranch! In the future please UseCodeTags when posting code or configuration.

It is looking for your DTD in the jar and not finding it. It will then look for it online and you are probably behind a proxy or something. Try changing it like below:



What version of hibernate are you using?

Thanks for reply.
I have tried your suggested way, but not get resolved.
Actually I am trying to access a remote database to which I have to connect through VPN client. After get connected through VPN client my internet connection is not working. I think for run my code internet connection is needed.
Please corrrect, if it is not right.

I created a simple java project and added jar files in eclipse -

antlr-2.7.6.jar
asm.jar
asm-attrs.jar
c3p0-0.9.1.jar
cglib-2.1.3.jar
commons-collections-2.1.1.jar
commons-logging-1.0.4.jar
dom4j-1.6.1.jar
ehcache-1.2.3.jar
ejb3-persistence.jar
hibernate3.jar
hibernate-annotations.jar
hibernate-commons-annotations.jar
hibernate-validator.jar
jdbc2_0-stdext.jar
jta.jar
log4j-1.2.11.jar
xerces-2.6.2.jar
ojdbc14.jar


By the first 3 lines of code in hibernate.cfg.xml, I can say that I am using hibernate 3.0 version.


Please assist me.

You might want to grab the distribution again. It should be finding it see the documentation here

http://docs.jboss.org/hibernate/core/3.6/reference/en-US/html_single/#tutorial-firstapp-mapping

Hibernate will not load the DTD file from the web, but first look it up from the classpath of the application. The DTD file is included in hibernate-core.jar (it is also included in the hibernate3.jar, if using the distribution bundle).


The fact that it appears to be trying to go to the web means its not finding it in the JAR. It should be there. Are you still getting the same exception after applying the change I mentioned or is it a different one? You also did not post the full stack trace.

You can re-download the distribution from here:
http://sourceforge.net/projects/hibernate/files/hibernate3/3.6.10.Final/

@Chinmoy Nag.

try to add all the six JAR files of required folder of Hibernate 3(as you are using that version), i think some JAR files are missing like "...\required\javassist-3.12.0.GA.jar" etc. I am not sure that this might be the solution but please try to add all six JAR files also copy and paste <!DOCTYPE..> element from predefined examples instead of manual typing according to the version you are using.
