Hi all,

I have one question. I have no connection to internet for server that have the application and i want to know if there is any posible to read mapping dtd file from anywhere in your webapplication project. I mean, if I have in windows (Where I have netbeans) and I put in code for example "C:\...\hibernate-mapping-3.0.dtd" this not work on linux.

Is there any possible to have this for all platforms?.

Thanks

I'm not sure what you mean by this, but Hibernate reads the DTD as a resource from inside the Hibernate jar. As far as I know, you shouldn't need to do anything to get it to work without an internet connection.

As nathanmoon said, hibernate uses it's own entity reolver on deploy, so the only time you're probably going to the internet for the DTD is in your editor/ide.

Most advanced editors will allow you to specify an 'XML Catalog', look in the editor/ide help files for this, or use google.

I had problems with that too.

The DTD resolving is done in:

org.hibernate.util.DTDEntityResolver.resolveEntity

hope this helps.

Answer and further question:

The .hbm.xml files require (or used to require - clarification please) a clause like:

<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 2.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">

or, if you don't want to use the internet you can place the physical DTDs in the server classpath with:

<!DOCTYPE hibernate-mapping SYSTEM "hibernate-mapping-2.0.dtd" >

And the obvious "further question":

How do I place the files in my WAR so that it does not rely on either the internet or the physical architecture of the machine?

(i.e.: with jBoss, in Windows you can put them in jboss/bin, but in Linux the DTDs have to be on the folder you execute "run" from - a pain if you are using /etc/init.d to start at boot - very bad place for DTDs).

Hi,

my previous posting is perhaps misleading.
In nearly all cases the standard mechanism
is working quiet well. For example
the standard mapping file header:



Hibernate is not loading http://hibernate.sourceforge.net/hibern ... ng-3.0.dtd
via internet. Instead it loads hibernate-mapping-3.0.dtd
via classpath from the hibernate.jar. This should work
on the server too.

to bmelloni: please check the version numbers.
If you use hibernate3 the header should look like the one above.

thanks steckemetz,

We had the right DTD name for the version in use, but there is a little known dependency that was breaking the behavior for us:

The XML parser must be "recent enough". Once I used Xerces 2.4.0, everything started working even with the original http-based DOCTYPE.
