Hibernate Client Jar

Hi All,

Quick suggestion, I just noticed that the JBoss 4.0.4 release comes with a hibernate-client.jar (I do not think that it was the case before, eg 4.0.3RCx).

Would it be possible to ship this client jar with Hibernate itself? It would be useful for whoever needs to receive objects that contain persistent collections over RMI.

Thanks!

Benoit

As an aside, I'd prefer if Hibernate was using jar names with versions... e.g. hibernate-3.1.3.jar

I know it was dismissed before on the ground of being easier to just replace the hibernate3.jar with the latest one... but I prefer explicit changes to "latest" and unclear jars....

Here here... library version management it always best done with a unique name per version. Just take a look at windows DLL mess to understand why, even they use soname like versioned filenames now with DotNET.

But its no problem to rename it before use, I always do.

It would also be good practice to see all the JARs in the lib/ directory of the distribution to follow suit. It just makes version management so much simpler and understand for everyone.

The only bad point is the possibility of duplicate JARs of different versions getting into the classpath, but this problem is so easy to spot its really a non-issue, than the opposite problem of having to dig into every jar to verify its version when you have a versioning concern. This becomes a waste on everyones time and so easy to fix at source.

YMMV

there is an open task for generating the hibernate-client.jar in context of the hibernate project. Anyone feeling up for it ? :)

Hi

I'd not mind giving a hand but isn't something already fixed for JBoss 4.0.4 GA? Would they recompile the hibernate code? or use a Jar? and if so would they split it?

So, let me know if it is still required and I shall have a quick look ...

basically what we need is to take a look at what was done in context of jboss and reproduce it in hibernate regi + hopefully a unittest or similar for checking if it actually is correct ;)

Hi All,

Well, thanks to Fisheye, I've found where JBoss splits the hibernate jar to a client:

See http://fisheye.labs.jboss.com/viewrep/J ... /build.xml

Code:

<!-- build hibernate-client.jar -->
   <!--
 <unjar src="${hibernate.hibernate.lib}/hibernate3.jar"
         dest="${build.classes}" />  
-->

<jar jarfile="${build.lib}/hibernate-client.jar">
   <zipfileset src="${hibernate.hibernate.lib}/hibernate3.jar">
<include name="org/hibernate/AssertionFailure.class"/>
<include name="org/hibernate/**/*Exception.class"/>
<include name="org/hibernate/collection/**"/>
<include name="org/hibernate/exception/Nestable*.class"/>
<include name="org/hibernate/exception/ExceptionUtils.class"/>
<include name="org/hibernate/engine/SessionImplementor.class"/>
<include name="org/hibernate/loader/CollectionAliases.class"/>
<include name="org/hibernate/persister/collection/**"/>
<include name="org/hibernate/pretty/MessageHelper.class"/>
<include name="org/hibernate/type/Type.class"/>
<include name="org/hibernate/EntityMode.class"/>
<include name="org/hibernate/util/**"/>
<include name="org/hibernate/proxy/**"/>
</zipfileset>
</jar>

I guess that the same approach would be easy to add to the hibernate build, if it is good enough for JBoss... should be ok for us...

I hope this is ok and am looking forward to see it integrated... :-)

many thanks

Benoit

hehe - but where is the test for it ? :)

But it was only expressed as ".... + hopefully a unittest..."

How is a piece of string for that kind of test...

I guess that Hibernate people will have to trust JBoss people...
Unless JBoss has a great test for it.

:-)

May be some words of caution in the release notes would be enough? ;-)

It would be a step in the right direction...

Cheers
