RE: [JBoss-user] JBoss Book

[Vincent Harcq]

All what I can tell you is that I bought the book and alreay received
two mails from flashline that warned me to download updated
version...for free.  The book is always acurate to latest 2.4 branch as
far as I have seen.
As the jboss site tells you it will be the SAMS printed book.
Do not hesitate one second to buy the book, 10$ for 448 pages.  Jboss is
explained in great detail.  You learn how to deploy on Jboss but also
what is an EJB container and how it does work from the trenches.

Subject: [JBoss-user] JBoss Book


Hi:
   I am considering buying the latest softcopy of the JBoss book written
by Scott. However, one thing that came to mind is that if I bought it
now, how do I get subsequent updates for that book? Is this going to be
the eventual printed book by SAMS?

Thanks

Is this problem not solved using EntityMultiInstanceInterceptor ?
I mean commit-option "any" / EntityInstanceInterceptor seems to
serialize access to the Cache. Then I agree with you.
Have you try to swicth to commit-option B/C /
EntityMultiInstanceInterceptor ?
What I don't understand yet is that plus the Entity/Method Lock
interceptors plus the locking-policy that can be used along with that.
That mixed with the fact that finder methods create multiple instances
and I am in a black hole...

RE: [JBoss-user] Mbean classloader bug !

[Vincent Harcq]

Marc,
This is as it should be, ok.
But,...
We loose the RE deployment facility because lib/ext is not dynamic.  We
have to shutdown/restart Jboss to see the changes.
Does Jboss 3.0 have re-deployment facility of lib/ext classes ?
Or is it recommended to put a "proxy" or "command" ejb between Mbean and
the EJB we want to talk to.
This EJB would never change and so does not need re-deployment.
I don't specifically see re-deployment of ejbs as a developement
facility but also as a configuration one.
Regards.
Vincent.

This way of defining resource is correct.
Go through a resource manager is not "absolutely" needed.

It should work as you explain it.  I will try that.

The use of resource-manager is simply an indirection inside the DD.
A summary could be :
A resource reference is unique for a Bean
A resource manager is unique for an ejb jar
A Connection Pool is unique for the JBoss server.

RE: [JBoss-user] Possible Bug with Minerva XADataSourceImpl and Opta's XDataSource

Hi,
Strange.
What is the trans-attribute of your session bean method ?
And more generally : is it really the jdbc layer that is in cause ?  Are you
sure to not have a transaction open ?

RE: [JBoss-user] JBoss and JDO

[Vincent Harcq]

Hi,
AFAIK, Sap announces the support of JCA through InQMy Resource Adapter.
Nothing about JDO.
I still don't see JDO as widely accepted and avoid to use it.

Are you talking about this product ?  Else can you point me which one ?  I
have looking for such a SAP RA for some time now and was always amazed by
the price of them.

Regards.
Vincent.

Hi,
About tomcat 3.2.3:
It is a minor update,
Just 3 jars have changed, the conf/ did not change at all.
Download from Jakarta, overwrite the tomcat/lib/ directory and it works.
About 2.4:
I think it was planned for end of july.

RE: [JBoss-user] Problem with cmp-jaws example

You find a 2.2 non compliant feature.  It is a 2.4 feature.
I will update the zip files on the web site.
For you to continue, comment out lesson.subject and lesson.hours in

[JBoss-user] EJBDoclet / JBoss entity bean Cache Problems / IllegalStateException in JDBCCommand

[Vincent Harcq]

Hi,
This problem may be interresting for ejbdoclet/jboss users.  But it can
happen to other as well, if you picked up your template PK class from a
book, ...

I faced a problem, in fact different problems during... well some time
now... on entity beans accessed by session beans.

It gives strange things like
   - having database updated but not the bean instance
   - IllegalStateException in JDBCCommand()
   - maybe others

I shout on JBoss, on the cache, on myself, ...

Very stange things that were in fact caused by a very simple stuff: the
hashCode() method of the Primary Key class.
If it contains private attributes, you have to make these as transient.

Another solution was to add a toString() method, which in fact is not bad
idea, a lot more easy to follow what happens in debug mode :)

For EJBDoclet, this means having :

==>   transient private int _hashCode = Integer.MIN_VALUE;   <== here we
are !!!

   public java.lang.String pk;

   public MasterDOPK()
   {
   }

   public MasterDOPK(java.lang.String pk)
   {
  this.pk = pk;
   }

   public java.lang.String getPk()
   {
  return pk;
   }

   public int hashCode()
   {
  if (_hashCode == Integer.MIN_VALUE)
  {
 _hashCode += this.pk.hashCode();
  }

  return _hashCode;
   }

   public boolean equals(Object obj)
   {
  if (!(obj instanceof com.hm.test.jboss.interfaces.MasterDOPK))
 return false;

  com.hm.test.jboss.interfaces.MasterDOPK pk =
(com.hm.test.jboss.interfaces.MasterDOPK)obj;
  boolean eq = true;
  eq = eq && this.pk.equals(pk.pk);

  return eq;
   }

Hope this can solve other nights ;)  It was a weird one really.

A good rule to follow is
If your entity bean and your db does not go OK
1. Play with commit-option A, B, C / understand what is a transaction (run
alone on the system)
2. Set the cache-size to min/max 1/1 OR to very big values as well as the
overager periods (to reproduce the problem)
3. don't shout on JBoss Cache bug
4. Look at your hashCode method of your PK Class, add a toString method
5. Blame yourself not JBoss

Regards.
Vincent.

RE: [JBoss-user] CDBean example - error when running Upload - jboss2.2.2

[Vincent Harcq]

It seems you have spaces in the directory where JBoss is installed ?
Don't do that.
IMHO Interest work because you do not have a intra-JBoss JNDI lookup.

Objet : [JBoss-user] CDBean example - error when running Upload - jboss2.2.2


I just downloaded jboss2.2.2 to try it out. Setup and ran the "interest"
example ok, but when running the upload client for "CDBean" example after
compiling and deploying with ANT, I get the following output in my jboss
console:

btw, I'm running win2000 workstation, not the server (does this matter?).
I've been struggling with this for a day now. Any help is appreciated.

RE: [JBoss-user] CMP Entity Bean using Opta2000 Driver - Has Anyone got this to work???

[Vincent Harcq]

I faced the problem also.
I cime back to using Minerva Pool DataSource instead of the inet one :


   org.jboss.pool.jdbc.xa.wrapper.XADataSourceImpl
   SQLServerPool
   jdbc:inetdae7:localhost
   sa
   
   etc...


This is for 2.4, on 2.2 change the package to minerva.

What remains a ? for me, it's that the doco explain it using inet
datasource.

BTW, have you a full license ? (I tried with the demo version, maybe a
problem...)
Have you tried 4.00 or previous versions ?
Have you strong relationships with the support to ask them the sources to
debug this problem ourselves, or ask them to look at the jboss code, I mean
they could have a return on investment,...

Vincent.

Remove the DTD from jboss.xml.  There is no validation anyway.
Normally JBoss will find it in jboss.jar but I am not sure on 2.2.

RE: [JBoss-user] Entity bean with special objects attributes?

[Vincent Harcq]

Your Vector may contain Serializable objects.
Object is the definition not the content.
A Vector full of Serializables IS Serializable.  (I never test it though...)

It's independant of the DB.
Parameter is in your ejb jar ?
How did you make the mapping in jaws (if you did - its' not necessary) ?
What is the exact message ?
WHen does it happen (at deployment, at run time) ?

RE: [JBoss-user] Opta2000 for MS SQLServer2000 - com.inet.tds.XDataSource

[Vincent Harcq]

Hi,
Thank you for your response.
I tried what you say (and other things) but I still get the error.
For info, the problem happens on XA_CONNECTION_FREE just after creating the
table.
When My table exists, I do not have the problem.
I could see if I can use my pool afterwards but I am now working with a demo
version (only 2 connections).  I will try again if I buy the license.
I will go back to JBoss pool for now.
Vincent.

I jump into the sources...cross post the mail...

TxCapsule line 523

 try {

endResource(idx, flag);
return true;
 } catch(XAException e) {

doBeforeCompletion() was missing.

The solution could it be so simple ?

isusing com.inet.tds.XDataSource instead of

[JBoss-user] [JBoss/Tomcat] Flat web application and classloaders

[Vincent Harcq]

Hi,
I am trying JBoss/Tomcat with several ejbs deployed as .jar and a web
application not deployed as a war but instead in tomcat/webapps/ROOT (it is
more easy for developement).
I have an entity PK class that is both in one ejb.jar and in tomcat/
I change it and redeploy my ejb.
I do NOT recompile the Tomcat version.
I attack my ejb with a client that have the new version of the PK class.
I receive a ClassCastException.
The ejb.jar is using the tomcat version.
Indeed, if I recompile the tomcat version the problem disappear.

Is this not a Classloader problem ?  the ejb.jar should only seen ITS pk
class.
Does I HAVE to use WAR to avoid that ?

Second Problem (but thisone is Tomcat I guess)
The "reloadable" attribute of Context in tomcat/conf/server.xml does not
seems to be taken into account.

TIA.
Vincent.

Hi jBossUsers,
I have 2 tables on two different DB (MySql - PostgreSql).
How can I use CMP with 2 Datasources ? jaws.xml and
standardjaws.xml don't let me specify more then 1 datasource
inside
With BMP I can get a connection from the pools without problems
but how can I achieve it with CMP ? If this is not possible I must
think that distributed transactions are only possible with BMP
otherwise how can I have two "create()" on different DB on the
same transaction ?
Thanks

Hi,
>In effect, it is like your 2nd case, since Strings are also Serialized
objects (The object

You mean your parameter is a String ?

>  public void setTestString(String testString) { this.testString =

I am not sure to follow you: the problem I have is not in the type of the
return object.
The problem is in the type of the parameter.

If the parameter is java.lang.String , int, java.lang.anything that is
Serializable : NO PROB.
If the parameter is com.mycompany.anything that is Serializable : PROBLEM.

The parameter.  Noit the returned object.

>Does your serialized object hold remote references?  I don't think that
those will serialize

No, in fact I am even not receiving anything I pass an Object (Serializable)
with 2 String in it.

It really drives me crazy, it is not very important but these rmi, jndi,

Thanks for responding.  I was not clear
Are you calling a method like that

Or Like that
SerialObject getSomething(SerialObjectB param) ?

The problem I have only happens in the second case.

Hmm...well, I hope that's not the case.  So far, everything has been working
great with Catalina 4.0b5, since I received help from this list on how to
get it working.  I am calling a remote method which returns a Serializable
Value Object -- seems to come back with no problem. (It in turn contains
both primitives and Objects)

Hi,
AFAIK, you will still get the error when you pass a non-primitive parameter
between Catalina and JBoss.  I do not think there is a solution for that.
The last trick that Simone post was
to marshal the parameters in a java.rmi.MarshalledObject, which is a
"primitive" (triple double quotes) for Catalina.  I come back to tomcat-dev
for that one yesterday.  No answers...

I checked out the list archives and noticed a bit of discussion earlier this
month on problems getting Servlets within Catalina to connect to JBoss.  Has
any of this been resolved? (I didn't see an answer anywhere).  I have tried
the nonaming option as many have suggested, but to no avail.

I'm getting the "java.net.MalformedURLException: unknown protocol: jndi"
error others have reported.

I've pasted the sample code I'm trying to execute below.

Thanks,

Here's the simple client code that my servlet tries to execute:
  // Sanity checkuses values copied from jndi.properties
  // just changed the hostname in the url to match the actual JBoss server
name
  System.err.println("Using these values:");
  for (Enumeration e = EJB_ENV.keys(); e.hasMoreElements();) {
String key = (String)e.nextElement();
System.err.println(key + "=" + EJB_ENV.get(key));
  }

  if (ejbCtx == null) {
try {
  ejbCtx = new InitialContext(EJB_ENV);
} catch (Exception e) {
  log("Error getting EJB context!");
  e.printStackTrace();
  return null;
}
  }

  try {
//Retrieve a handle to the Home object
System.err.println("About to lookup up: " +  userJNDIName);
Object o = ejbCtx.lookup(userJNDIName); // <- Breaks here
UserHome uh = (UserHome)PortableRemoteObject.narrow(o, UserHome.class);
return uh.create();

RE: [JBoss-user] JBoss + Catalina JNDI Probs

[Vincent Harcq]

Hi,
AFAIK, you will still get the error when you pass a non-primitive parameter
between Catalina and JBoss.  I do not think there is a solution for that.
The last trick that Simone post was
to marshal the parameters in a java.rmi.MarshalledObject, which is a
"primitive" (triple double quotes) for Catalina.  I come back to tomcat-dev
for that one yesterday.  No answers...
Vincent.

I checked out the list archives and noticed a bit of discussion earlier this
month on problems getting Servlets within Catalina to connect to JBoss.  Has
any of this been resolved? (I didn't see an answer anywhere).  I have tried
the nonaming option as many have suggested, but to no avail.

I'm getting the "java.net.MalformedURLException: unknown protocol: jndi"
error others have reported.

I've pasted the sample code I'm trying to execute below.

Thanks,
Jason

Here's the simple client code that my servlet tries to execute:
   // Sanity checkuses values copied from jndi.properties
   // just changed the hostname in the url to match the actual JBoss server
name
   System.err.println("Using these values:");
   for (Enumeration e = EJB_ENV.keys(); e.hasMoreElements();) {
 String key = (String)e.nextElement();
 System.err.println(key + "=" + EJB_ENV.get(key));
   }

   if (ejbCtx == null) {
 try {
   ejbCtx = new InitialContext(EJB_ENV);
 } catch (Exception e) {
   log("Error getting EJB context!");
   e.printStackTrace();
   return null;
 }
   }

   try {
 //Retrieve a handle to the Home object
 System.err.println("About to lookup up: " +  userJNDIName);
 Object o = ejbCtx.lookup(userJNDIName); // <- Breaks here
 UserHome uh = (UserHome)PortableRemoteObject.narrow(o, UserHome.class);
 return uh.create();
   } catch (Exception e) {
 log("Error getting an User object!");
 e.printStackTrace();
 return null;
   }

This module is now integrated into version 2.3 - current CVS.
If you want to take this to JBoss 2.2.1, then you have to build the module,
it will create this jar.

It is mine also.
I think My problem is a bit different, as I have an ejb jar A contains the
session bean and ejb jar B contains the entity that will be removed through
the session bean.
I have verified that the EntityEnterpriseContext of ejbjar B have an object
in it that has a Classloader of ejbjar A.
I am still looking how it can happen since my understanding of
EntityInstanceInterceptor is that access to EntityEntrepriseContext "object"
can only be done through the EntityCache which is attached to the entity so
to the ejbjar B classloader.
I have also verified that access to EntityEnterpriseContext may be done
without going to EntityInstanceInterceptor.

Before removing your entity, can you try to run any getter method on the
remote interface.  just before calling remove(), it should solve your
problem.

I am pretty sure there is a problem in the instances pool somewhere, I also
receive something similar to that.
The trick is tio call any dummy remote method before calling remove.
Please help me figure out what happen :
Do you play with 2 session beans in 2 different ejb jar here ?
Thanks.

Jim,
You work with latest cvs version do you ?
Then replace
log4j.rootCategory=DEBUG, Default, Console
by
log4j.rootCategory=INFO, Default, Console

IMHO, this should be the default in cvs.

RE: [JBoss-user] Catalina and Jboss2.2.1 InitialContext error

[Vincent Harcq]

Yes, no problem with -nonaming : catalina.bat run -nonaming.
server.xml :


And all JBoss client JAR files in E:\Projects\web\WEB-INF\lib

Nothing else changed to catalina installation directory

Oh yes, another one,
jndi.properties is not read (if I remember well) so I have to manually
System.setProperty "java.naming..." just before calling new InitialContext()

RE: [JBoss-user] Catalina and Jboss2.2.1 InitialContext error

[Vincent Harcq]

Nope.

Scott, my gentle jndi guru, does it make sense to change NamingContext
so that it can understand "jndi:", then use for java.naming.provider.url
something like "jndi://localhost:1099" to avoid this problem with catalina ?
Or is it Catalina the source of the problem ?

I'll try.
This problem is the same as

But with your explanation I see better where to look at.

RE: [JBoss-user] Obscure issue (bug?) with CMP using column mapping

[Vincent Harcq]

Hi,
if you run remote= fBPK() then remote.remove(), can you try a
remote.getanyfield() in between and let me know if it solve the problem or
not.  I also saw something similar to that.
Thanks.

Yes, the Home and Remote interfaces of EJB B, you got the "data" from JNDI
but you still need the class that the "data" will fill.  An expert will
explain this with more difficult words, but that's the idea :)

Hi,
you do not need to define findAll method in jaws.xml, it is magic.
Anyway, your definition of finder method is not correct at all.

I agree...partially... with your comment, when I will write docs on that, I
have to be clear it is JBoss specific.
Partially because for a value object such as Quantity (a double and a
String) or Amount, ...  the EJB 2.0 entity bean relationship is not a
solution.  It is for Address, and these kind of objects.
With dependant object it would have been possible (even if I do not like the
idea) to have a Quantity d.o., make a client view of it and solve the OO
design.  Without I need to serialize my Quantity or decompose it in two
primitive type fields, both solutions being unacceptable for me (it is a
strong word, but cmp are very far from OO design for now)
These kinds of objects (we can them as java primitive types extensions in
the business object world) were the main reason for my change.

Thanks for opening the discussion.

[JBoss-user] Nested Properties, dependant value objects, ...

[Vincent Harcq]

Hi,
I have made added some feature to the way "dependant value objects" are
mapped to table fields.
This is for example when I have a UserBean cmp entity bean that have a
cmp-field address of non primitive type Address, and I want to store each
fields of Address into the database using a specific Jaws feature.
IMHO, with dependant objects being dropped of EJB 2.0, I think this feature
is important because the standard way to that with ejb 2.0 would be to
define a cmp bean for my value object which is really going too far.

Up to now, this was possible with the fields of Address being public.
This is still possible and needed in the special case the dependant value
object is a PrimaryKey class of another enity bean.  (IMHO, this is a nice
feature to make relationships between ejb without having do use a remote
interface field because it permits direct sql between tables, and keep an OO
relationship that you loose if you map the pk fields as primtive type.

>From now it is also possible when the fields of Address are private, have
corresponding get/set methods, if Address have a no argument constructor,
and if Address is serializable.

As it is my first commit to jboss, I would like that somebody validate my
work.  Let me know of problems and I'll fix them directly.  I also read that
somebody have begin to document this feature, I would like to add this in
his document and commit the all to jboss-docs.  Keep me inform please.

The preferred way to do it is this:

1. Define address in the cmp bean :
public Address address;
2. Define the dependant value Object that must have a no argument
constructor.
public class Address implements Serializable
{
private String line1;
  private String zipCode;
// etc...

public Address() {}

public String getLine1() { return line1; }
public void setLine1(String line1) { this.line1 = line1; }
// etc...
}
3. in ejb-jar, define address as a field
address
4. in jaws, define how to compose/decompose this dependant value object to
database fields, for example :

address.line1
addr_line1


address.zipCode
addr_zip

Be carefull here that the fields that are not mapped will not be taken into
account.  I had to choose between this and an automatic mapping feature.
IMHO, an automatic mapping feature is not necessary and could cause
problem/confusion.

To finish, you have to know that it is recursive, you can so have for
example address.zipCode.code with a Zip object.
That's all folks.

Future possible improvements :
1. Multiple tables definition for one bean (Borland permit that, does JBoss
want that ?)
2. Collection type support for dependant value objects (one bean to multiple
rows/multiple tables) (become quickly a nightmare if you have a cmp bean
that have a COllection of dependant value objects that each have a
Collection of dvo, etc...  or if you want to be able to do lazy
loading/dirty checking on the collection, ... ; and with ejb-relationship of
ejb 2.0 is it "really" needed ?)

RE: [JBoss-user] Question : RollbackException, BMP entity bean, ejbStore,...

[Vincent Harcq]

Hi,
Say you would have calls setName() instead of getName(). Then ejbStore call
would be normal for you right ?
ejbStore is called to be sure the database is synchronized when the ejb
change, and the ejb could potentially change by doing  any remote
invocations, be it a get or a set.
So that's normal behaviour and is not linked to anything in particular
inside JBoss, it is standard spec.
Vincent.

RE: [JBoss-user] Setting up the naming provider

[Vincent Harcq]

Your remark is for when accessing JNDI server outside JBoss.
For the simple case : one jboss server being the JNDI server itself, if I
remember, from within one JBoss VM, it is better to specify nothing at all
and if nothing is found, the JNDI client will know the JNDI server is itself
and avoid Network call.
And that would be the WARNING that JBoss gives when he found a
jndi.properties in its classpath at startup : "Hey you do not need to do
that! I know what I am doing! You will make network round trip for nothing!"
To be honest I am not sure about the explanation but the fact is I do not
need jndi.properties from inside JBoss to make JNDI lookup.

RE: [JBoss-user] Setting up the naming provider

[Vincent Harcq]

Hi,
If you use Tomcat 3.2.1, you can put jndi.properties in the Tomcat CLASSPATH
and you do not need any System.setProperty().  That's how JNDI client has to
find its property.  And that's the more proper usage of it since you do not
need to put JNP stuffs somewhere else.
But it really depends if your JNDI client does not mess with these System
properties.  If the client overwrite them somewhere, jndi.properties will be
no help.
When I tested Catalina, I faced the problem that they come with a JNDI
implementation that harcode factory.initial and provider.url somewhere, so
you have to overwrite them in the code.  The good solution to that is to
use -nonaming on Catalina so that Catalina does not overwrite these System
properties.
I do not know with Embedded Tomcat, I do not use that.
So you have to look at what your JNDI client do and verify, when you create
a InitialContext, what the values are inside System.properties to be sure a
bad boy did not change them somewhere.
Vincent.

As you said the spec does not allow using Threads inside an EJB.  But it is
permitted inside a client class. Maybe the answer to your problem is using a
client class ?
Or JMS ?

Is'nt there a GUI deployment tool for JBoss that can take inputs, compose
deployment descriptors, bundle all the classes, resources into a jar and
deploy it, Like what comes with Sun's J2EE Reference implementation?
having to write all the deployment descriptors in xml then putting them all
in a jar through command lines and deploying the apps seem to be cumbersome.

Is there an easy way out?

To start it simply double click ejx.jar under bin/ (Windows)
or run a script java -jar ejx.jar (Unix)

Objet : [JBoss-user] Can I find a Deployment tool?


Hi,

Is'nt there a GUI deployment tool for JBoss that can take inputs, compose
deployment descriptors, bundle all the classes, resources into a jar and
deploy it, Like what comes with Sun's J2EE Reference implementation?
having to write all the deployment descriptors in xml then putting them all
in a jar through command lines and deploying the apps seem to be cumbersome.

Is there an easy way out?

RE: [JBoss-user] exception handling

[Vincent Harcq]

Hi!
Do not use RemoteException but your a new one you create.
throw MyException("blablabla");
RemoteException is considered System is catch by the server and rethrown.
A custom Exception is also catched but rethrown the same.

Objet : [JBoss-user] exception handling


Let's consider the following remote method implementation (this is the
implementation of a method defined in a remote interface of an EJB):

public UserSession getSession ( String sessionId, String requestId,
String requestIdentifier )
throws RemoteException, CreateException, FinderException
{
UserSessionHome home = ( UserSessionHome ) getHome
("gatekeeper/UserSession", UserSessionHome.class);
UserSession session = home.findByLastRequest ( sessionId, requestId,
requestIdentifier );
if ( session.timedOut () )
{

System.out.println ( "session timed out" );
throw new RemoteException ( "Session Timed Out" );
}
session.setNew ( false );
session.setRequestId ( forgeId ( 30 ) );
session.setLastAccessedDate ( new java.sql.Timestamp
 System.currentTimeMillis () ) );
return session;
}


Now, this is a code that's executed by a client

try {
session = gatekeeper.getSession ( session.getSessionId (),
  session.getRequestId (),
  "get session again test" );
textarea.append ( "sessionId: " + session.getSessionId () +
"\n" );
textarea.append ( "requestId: " + session.getRequestId () +
"\n" );
textarea.append ( "isNew: " + session.getNew () + "\n" );
} catch ( java.rmi.RemoteException e ) {
textarea.append ( "Remote Exception: " + e.getMessage () );
} catch ( Exception e ) {
textarea.append ( "couldn't get the same session\n" );
stackTrace ( e );
}

I *would* like to catch a RemoteException with my message (ie "Session Timed
Out" ) but instead I get my exception nested in another RemoteException:

Remote Exception: RemoteException occurred in server thread; nested
exception is:
 java.rmi.RemoteException: Session Timed Out

That is, Ideally, I would create a custom exception, TimedOutException,
which I'd like to catch appropriately, but that's apparently impossible, and
for the very moment, it is quite annoying for me.

Does someone know how to solve this problem ?

Thanks in advance,

candide kemmler
