Hibernate in action: All Jar files in lib folder?

[Frank Malinowski]

I have another book about Hibernate and it recommends placing all of the Hibernate, Hibernate Extensions, and HSQLDB jar files into a lib directory at the base level of your project directory. It seems to me that this requires you to either develop all projects in the same directory structure or to have multi-megabyte lib directories in every project directory.

Do you agree with this setup or does your book recommend proceeding another way?

I'm asking because I am just starting to learn Hibernate and Ant and when I set up Ant I simply set a couple of environment variables so that my system knew where to find Ant and then I could use it to build any project, no matter where it is located in the directory structure. It seems that something similar to this would be the best solution for Hibernate as well.

Thanks,

Frank Malinowski

Well, this is usually the job of your IDE. For example, I point all my work to a central Hibernate 2.1 directory, which is mapped as a "Global Library" in IntelliJ IDEA. There should be something similar in Eclipse.

[Gavin King]

It is usual to copy all dependant jars into the lib directory of a project. I dunno about the stuff in HibernateExt though, that seems a bit strange...

[Gavin King]

Do you do it that way Christian?

That is not really the Done Thing in eclipse-land, I think...

[Christian Bauer]

I have a separate Global Lib, which is called "HibernateExt", and it will add its lib/src/doc path to my project.

all of the Hibernate, Hibernate Extensions, and HSQLDB jar

I hope you are not really meaning that. The README file in the lib directory of Hibernate distro gives you the exact list of needed jars.

However for working inside an IDE (just for editting you need only hibernate jar and commons-lang). For running your application from inside read the above.

Yes, I really mean that. I am simply telling you what the Hibernate book that I currently own says to do.

Second, I am not using an IDE at the moment. I am doing everything via the command line.

Finally, the README file tells you how to run the Demo and Tests that come with Hibernate. This doesn't tell me how to set it up when running my own projects.

FYI, the book in question tells you to set up a project hierarchy as follows:

1) Create a project directory.
2) Create subdirectories: src, lib, data.
3) Copy hsqldb.jar to your project/lib directory.
4) Locate the lib directory in the Hibernate directory and copy ALL of its contents into your own project lib directory.
5) Copy hibernate2.jar into your project/lib directory.
6) Copy the entire contents of hibernate-extensions-2.1.2/tools/lib into your project/lib directory.
7) Copy hibernate-tools.jar into your project/lib directory

It even tells you what the contents of your project/lib directory will be after this process and it contains 43 items weighing in at 11.3MB.

This is the reason I asked for advice. I'm new to Hibernate but this seemed odd to me.

:-(. Please take into account my suggestions. They will work.

Maybe, the hibernate extension will be needed if you use Hibernate Ant tasks to build the project.

Good luck cleaning the project! ;-)

[Lasse Koskela]

Let me state that it makes sense to include the dependencies of a project in the same version control system. If all your projects are pointing to a single, centralized library, you're practically forced to upgrade all your projects at the same time...

I read the wrong README file earlier and see what you were referring to now. However, since I am new to Enterprise development I'm still unsure when the "optional" jars would be needed so it seems that I should probably include them when starting out.

I will probably try the IDE suggestion at a later date.

Now, i'm use Eclipse to develop application with Hibernate.

I'm MUST use hibernate extension (hibernate-tools.jar) for code generation.

 
<target name="generate" description="Generate Hibernate Source File">
<java classname="net.sf.hibernate.tool.hbm2java.CodeGenerator" fork="true" dir=".">
<classpath>
<fileset dir="${lib}">
<include name="**/*.jar" />
</fileset>
</classpath>
<arg value="--output=${src}"/>
<arg value="--config=config-hbm.xml"/>
<arg value="${src}/com/spns/hbm/Team.hbm.xml"/>
<arg value="${src}/com/spns/hbm/Player.hbm.xml"/>
<arg value="${src}/com/spns/hbm/TestTable.hbm.xml"/>
</java>
</target>

I think that when the README refers to buildtime it refers in fact of building Hibernate distro.

Working with Eclipse (just for editing) requires only hibernate2 and commons-lang jars. As for real deploy I use only a few of the enumerated jars (cglib, commons (collections, dbcp, lang, logging, pool), connector - I run inside a container -, dom4j, ehcache, jdom, odmg, xalan, xerces, xml-apis).

And you should be use jta.jar for standalone application...
