Last Modified: 2013-11-24

I am using WSAD. I am getting below syntax error when I am try below code for hbm.xml file

<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"

Syntax error at line : "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
Error message : operation timed Out : Connection

can you please help me what does this error mean and how to correct.

Watch Question

are you sure you can connect to the internet from your computer ?
try open the link in internet explorer


I am able to access internet I dont have any problem. I am not sure why I am getting syntax error.
What is WSAD? Is it websphere ? I assume you are getting this error when you try to make a XML mapping file and not while actually executing any code.

Go to your IDE options, most IDEs try to cache the XSDs so that they can provide you good validation mechanisms. Disable such validations based on XSD for your IDE.



java.lang.UnsupportedClassVersionError: org/hibernate/MappingException (Unsupported major.minor version 48.0)
This suggests to me a mismatch of Java versions. Are you using Java 1.5 for your code? It may be that Hibernate or one of the other libraries you are using requires Java 1.5 and you are not using it..?

The timing out of the connection is probably not the real cause of the problem - the real error is probably this class mismatch.

Not the solution you were looking for? Getting a personalized solution is easy.

Ask the Experts


I dont have jdk1.5. I am working on 1.4


I am using WSAD is there any configuration I have to do before running hibernate programs
java.lang.UnsupportedClassVersionError: org/hibernate/MappingException (Unsupported major.minor version 48.0)
I can only guesses, like you might have WSAD on top of JDK 1.5 and there is a mismatch between your compilation and runtime JRE

Which version of Hibernate are you using?
