Hi Stephen,

thank you so much! Think this will help many user.
I checked in your stuff under the new Forrest document dir.

Hi Armin,

Please find below "howto" to deploy ojb as an ear file.

Here is an example of the .ear package structure. It is redeployable
without having to restart Jboss.

/ejb.jar/
...EJBs
...META-INF/
......ejb-jar.xml
......jboss.xml
......MANIFEST.MF 

/web-app.war/
...JSP
...WEB-INF/
......web.xml

/META-INF/
...application.xml
/ojb.jar
/[ojb required runtime jar] 

/OJB.properties
/repository.dtd
/respository_internal.xml
/repository.xml
/repository_database1.xml
/repository_app1.xml
/repository_database2.xml
/repository_app2.xml


There are two approaches to use OJB api in the ejb.jar file.

1. To create a Manifest.mf file with classpath attribute that include
all the runtime jar required by OJB (Very important to include all
required jar). The sample below works fine.

Class-Path: db-ojb-1.0.rc6.jar antlr-2.7.3.jar commons-beanutils.jar
commons-collections.jar commons-dbcp-1.1.jar commons-lang-2.0.jar
commons-logging.jar commons-pool-1.1.jar jakarta-regexp-1.3.jar

Note: If you to include the jar file under a directory of the ear file,
says /lib/db-ojb-1.0.rc6.jar and etc. At the classpath attribute it will
be something like; 

Class-Path: ./lib/db-ojb-1.0.rc6.jar and etc (The "." in front is
important)

2. To add the required jar file as a "java" element in the
application.xml file. 

        <module>
                <java>antlr-2.7.3.jar</java>
        </module>
        <module>
                <java>commons-beanutils.jar</java>
        </module>
        <module>
                <java>commons-collections.jar</java>
        </module>
        <module>
                <java>commons-dbcp-1.1.jar</java>
        </module>
        <module>
                <java>commons-lang-2.0.jar</java>
        </module>
        <module>
                <java>commons-logging.jar</java>
        </module>
        <module>
                <java>commons-pool-1.1.jar</java>
        </module>
        <module>
                <java>db-ojb-1.0.rc6.jar</java>
        </module>

Note: To use this approach, all the library had to be in the root of the
ear.


(This was tested on Jboss 3.2.3)

Stephen

Hi Armin,

Thanks for your help + suggestion. I had successfully package everything in an ear file and it is redeployable.

Congratulation! This isn't everybody's job ;-)


So nice. Actually, there is not
much changes to what was suggested in the ojb deployment doc.


Stephen it would be really great if you could write a "howto" about your experience with OJB .ear packing (no big thing, only a few lines in your on words how you get it work) to integate it in "deployment" page.

Armin


I had successfully uses 2 methods to get it work on Jboss 3.2.3.

1. To include ALL jar file required by OJB during runtime in the classpath of the manifest file.

Class-Path: db-ojb-1.0.rc6.jar antlr-2.7.3.jar

commons-beanutils.jar c

ommons-collections.jar commons-dbcp-1.1.jar

commons-lang-2.0.jar comm

ons-logging.jar commons-pool-1.1.jar jakarta-regexp-1.3.jar

***The carriage return at the end of the classpath is not required.

2. The second approach is to add the required jar file as a "java" element in the application.xml file. To use this method, all the library had to be in right at the root of the ear.

<module>
<java>db-ojb-1.0.rc6.jar</java>
</module>

...etc

NOTE: If only include ojb jar file in the classpath it won't work.

Regards,
Stephen

Hi Stephen,

now I'm be stumped, your structure looks fine to me. Did you set a
carriage return at the end of each Class-Path line?
hmm ...try to post your problem at the jboss list and let these guys solve your problem;-).
Sorry I can't help more.
Please keep me up-to-date (seems to me very important for

other user).

Armin

Whereas if I access OJB through JNDI, I have no problems.

Please help

Hi Armin,

If I were to have multiple ejb.jar that have it owns

repository (class



descriptor, jdbc-connection-descriptor). OJB will only found

the jdbc



connection descriptor of the ejb.jar that is firstly

deployed. What is



the correct strategy for deployment of multiple ejb.jar

with it own

bundle of OJB.jar in a same JVM?


hmm, each .ear file is separate application and should

have its own

classloader. Thus if you include all ojb jars + jars OJB

depends and

the config files in each .ear file you can use different .ear

applications


with different config files.
But I think it is not possible to use different OJB config
files in the same .ear file (same application), because all ejb.jar

files use the

same classloader.
If you have multiple ejb.jar files in one .ear file, each

ejb.jar file


will find the same config-files (first found by classloader).

Why do you need this - can you explain?

Armin
