Re: [JBoss-user] Anyway to clean memory usage after run jboss?

Junjie,
Neglect if you already knew this.
Just adding to what Paul said. Hit ctrl + Esc on your key board and you will 
be able to see all the processes running on your RedHat 7.1. Select all 
relevant java processes and kill them mercilessly :-)

JBossCMP stores objects in serialized form using a MarshalledObject.  I 
copied this code from JAWS, so I am not sure of the reasons.  I think it 
has something to do with portability of stored objects, but the real 
reason is it works.

2002-05-15 Thread Simon Stewart

Thanks fir the heads up, but I don't think that's it. I'm only shoving
strings, Dates and URLs in there ATM, and none of them come close the
64K limit. Also, manually deserializing them works without problems.

I've gone back to using Strings and being a bit more careful with how I
manipulate the data. Pity.

RE: [JBoss-user] Deserializing objects to DB

2002-05-15 Thread James Higginbotham

I have seen this one on mySQL - maybe some of it will translate.
Basically, if you are letting Jboss create the tables if they don't
exist, it will create the row as a BLOB. In mySQL, BLOB is limited to
64k, so you really need a LONGBLOB. If the serialized byte stream gets
cut off, the built in unmarshal logic will not be able to handle the
incomplete serialization and will pass it to the application as a byte
array. Be sure your column has the right SQL type to accommodate your
size needs. And, if Jboss is creating the table with the wrong sized
column type in Postgres, then create the table manually and tell JB not
to create or remove the tables within the jbosscmp-jdbc.xml file. 

Here is my jbosscmp-jdbc.xml and table structure that works in JB 3.0:



   java:/myDatasource
   mySQL
   false
   false
   false




WorkflowStorageBean
workflowejb

workflowId
workflowId
VARCHAR
   VARCHAR(64)



data
data
   JAVA_OBJECT
   BLOB

   




CREATE TABLE workflowejb (
  workflowId varchar(64) NOT NULL default '',
  data longblob
) TYPE=InnoDB;

HTH,
James

I'm starting to suspect that JBoss might be the culprit here. If I
manually extract an object from the byte array, it turns out to be a
java.rmi.MarshalledObject when the expected class was java.lang.String.

Can anyone shed some light on this? I'm using CMP 2, if that helps.

RE: [JBoss-user] Anyway to clean memory usage after run jboss?

2002-05-15 Thread Paul Cody

What do you mean by "does not release memory"?  You should never have to
restart the machine, this is completely unnecessary.  Just kill the java
process that is running JBoss.  If your application is not shutting down
cleanly, think about any threads that you may be creating, esp things like
java.util.Timer or interaction with the JMX Timer service.  If necessary,
you can run a debugger to see where the threads are waiting.

[JBoss-user] Deserializing objects to DB

2002-05-15 Thread Simon Stewart

I have a simple EJB that has three fields ("ID", a "key" and a "value")
Key is a string, and value is given as being of class
java.io.Serializable, so this class represents a basic key/value pair.
Data appears to be serialized to the database okay (Postgres 7.2.1,
column type BYTEA) but as a byte array. (I'll paste it below so someone
can correct me when they want to)

On deserializing the data, I get ClassCastErrors. The class being
recovered from the DB is "[B" according to the exception being thrown,
and that's just plain wrong. Anyone else seen this or got any ideas? A

deserializedObject.getClass().getName()

also returns "[B". More poking about reveals that this is a byte array.
Is it a quirk of my JDBC driver that this happens, or is this something
to do with JBoss' handling of serialzied objects in EJBs? I can post
code, should people need it.

Currently using Postgres 7.2.1, JDK 1.4 (from Sun), JBoss 3RC2, the
usual suspects :)

Regards,

Simon

We tried that, using the following dir structure:

Where webapps was listed in the URLDeploymentScanner. We also tried
where webapps/my-web-app.war was listed in the URLDeploymentScanner.
Both don't seem to work. Any other thoughts? I'm running JB 3.0 (March

[JBoss-user] Anyway to clean memory usage after run jboss?

2002-05-15 Thread Junjie Ding

I am running JBoss in Redhat linux 7.1(Linux 2.4.2-2), using jdk1.3.1_01 and
JBoss-2.4.4_Tomcat-4.0.1.

The problem I have is JBoss doesn't release all the memory it took after I
ran it
and my application. The memory it takes increases as more beans I use in my
application
but it doesn't release them. Even if I shut down JBoss. The only work around
I have now
is restart the machine, which is ridiculous. I'm not sure if this is because
of memory
leak in jboss or jdk1.3.1.

Can anybody point me out if this is because of JBoss and the solution? Any
related
information will be helpful and appreciated!

Thanks

Does convertions of not-JBoss-DD's are done by FoeDeployer? We could
have an abstract converter that will be subclassed by converters for
different app servers (to look ahead).

[JBoss-user] JBoss WL Emulator

2002-05-15 Thread Andreas Schaefer

Hi Geeks

Let's go and kick some ass with our project "kick-ass".
First can everyone (even when you already did) send ME
an email when you are interested in spending some time or
resources towards this project.

This is my design I came up with:
- New deployer (FoeDeployer) which works
   like an EJBDeployer
- Main or EJB-Deployer figures out that this
   archives isn't off JBoss type and hand it over
   to the Foe-Deployer
- The Foe-Deployer reads the DDs, converts them to
   the JBoss DDs
- Then the Foe-Deployer hands it back to the EJB-
   Deployer and off we go

If somehow possible I would like to have an implementation
running in a month, plain and stupid. So we should take the
most simple case and write the deployer for it. That is what
I would like to have covered:
- JNDI names
- Resources and Resource Managers
- 1 to 1 CMP tables
- Transactions
- Finders
- Message Driven Beans

Until the end of the week I will start creating the Foe-Deployer
and add the code to JBoss.

Have fun

Try to find "deploy" directory  starting from %JBOSS_DIST%. That's it.

[JBoss-user] Deploying a war file into integrated Catalina, Jboss 3.0

2002-05-15 Thread Derick

How do you deploy a war file into the integrated Catalina?
Copying it to D:\Jboss\catalina\webapps, expanded or not does not seem to
load it.

Thanks
