Re: OJB in J2EE Enviroment

Wed, 23 Oct 2002 12:07:24 -0700

Hi again,

Going over Mickey's solution again, I noticed that I had failed to add the jakarta-ojb-xxx.jar file into the .sar file. When I did this all the ojb stuff loaded cleanly, but the web console wouldn't load (exception output follows). When I removed the .sar file, jboss loads everything fine including the web console (and the web console works).

OK, now you "only" have a packing/deploying problem ;-)
I don't have experience in packing of .ear -files, sorry.

Maybe Mickey could give some more assistance.
Here is an article about j2ee packing
http://www.onjava.com/pub/a/onjava/2001/06/26/ejb.html

When do my tests I put all related OJB files in the jboss working dir
(jboss/bin), but this is NOT recommended for production environment.

Armin

Hi Armin and Mickey,

I made some progress and have some questions remaining.  I am using
Win2K, jboss-3.0.3 and ojb-0.9.7.

Following Armin's instructions, I did this:

> put the jakarta-ojb-xxx.jar and
> jakarta-ojb-junit-xxx.jar in
> ...\jboss-3.0.3\server\default\lib
> Put ejb-jar.xml, jboss.xml and ojb-beans.jar of
>  ...\jakarta-ojb-0.9.7\target\srcejb in
> ...\jboss-3.0.3\server\default\deploy
>
> Start jboss.

I also needed to add commons-lang-0.1-dev.jar to
...\jboss-3.0.3\server\default\lib
and then jboss started cleanly, including:

Note that following Mickey's approach, I put the jars in
...\jakarta-ojb-0.9.7\lib into
his jakarta-ojb.sar file and put that file into
...\jboss-3.0.3/server/default/deploy

I get my initial error about the service not being registered:

Hi Armin,

I'm having trouble while following your instructions.  This is what I

did:



1) Changed the OJB.properties to


ConnectionFactoryClass=org.apache.ojb.broker.accesslayer.ConnectionFacto
ryPassThroughImpl

set
useAutoCommit=0
too

seems to be a classpath problem or deploy order problem,
jboss could not found the mbeans.
To *test* the deployment of the mbeans you could try the following:

put the jakarta-ojb-xxx.jar and
jakarta-ojb-junit-xxx.jar in
...\jboss-3.0.3\server\default\lib

Put ejb-jar.xml, jboss.xml and ojb-beans.jar of
...\jakarta-ojb-0.9.7\target\srcejb in
...\jboss-3.0.3\server\default\deploy

Start jboss.
Now jboss should deploy the mbeans and
you should be able to lookup the sample beans.




7) Put ejb-jar.xml, jboss.xml and ojb-beans.jar of
...\jakarta-ojb-0.9.7\target\srcejb in
...\jboss-3.0.3\server\default\deploy

BTW, the ojb-jar.xml contains
the ejb-jar.xml and jboss.xml files,
thus you should not put thi



s files in the deploy dir




regards,
Armin






2) bin\build jar

3) bin\build war

4) ant -buildfile build-xdoclet.xml

5) Put the MBean declaration

<mbean code="org.jboss.ojb.odmg.ODMGFactory"
      name="DefaultDomain:service=ODMG,name=ojb/defaultODMG">
 <attribute name="JndiName">ojb/defaultODMG</attribute>
</mbean>
<mbean code="org.jboss.ojb.pb.PBFactory"
      name="DefaultDomain:service=PB,name=ojb/PBAPI">
 <attribute name="JndiName">ojb/PBAPI</attribute>
</mbean>

in ...\jboss-3.0.3\server\default\deploy\user-service.xml

6) Put dist\ojb-servlet.war in
...\jboss-3.0.3\server\default\deploy

7) Put ejb-jar.xml, jboss.xml and ojb-beans.jar of
...\jakarta-ojb-0.9.7\target\srcejb in
...\jboss-3.0.3\server\default\deploy

JBoss gives the errors below at startup.

Can you see what I've done wrong?

Thanks very much,

Phil

Hi Thomas,

Get the current CVS head or last source code version.
(When using the CVS head you will find more sample beans)

Generate the docs with
bin\build.bat doc

Generated docs you will find under .../target/doc
Instruction for deployment in
jboss see:
User Documentation/Deployment

To generate the shipped sample beans:

- first build the ojb jars
bin\build.bat jar
- then build the sample beans jar using xdoclet
ant -buildfile build-xdoclet.xml
the jar and the generated src code
you could find under ../target/srcejb
(When using a different AppServer then jboss,
change the build-xdoclet.xml file doclet task, see
xdoclet documentation)
Deploy the jar in your AppSever and run one of
the test clients (or try to run the AllTests.java client).

The original source code of the sample
beans you could find under ../src/ejb/...

repository.xml:
For the jdbc-connection-descriptor tag Matthew had
introduced an eager-release attribute, when using
jboss (tested for 3.0.3) this should be set 'true'
(default was 'false'). If set 'true' the obtained connection
by the PB was "closed" after each Statement use.

Sample:
....
<jdbc-connection-descriptor
   platform="Hsqldb"
   jdbc-level="2.0"
   jndi-datasource-name="java:DefaultDS"
   username="sa"
   password=""
eager-release="true"
 />

Currently we only test under JBoss 3.0.3
(3.x versions <3.0.3 cause trouble)


HTH

Armin

Hi all

Did anyone ever use OJB in a J2EE environment? If so what are the
experiences? I just read it smoothly integrates into it but no

Are there any details around about how to use OJB inside a J2EE
