Re: [JBoss-user] C/C++-Client connecting to JBoss via JMS

[Langelage, Frank]

Hi Holger,

we are thinking about different scenarios to advance our legacy "old" 
ERP-System with "new" modules written in java/j2ee running on jboss.
I implemented an JCA interface to call "old" procedures from "new" java 
technology.
But the other way is not quite clear so far. I thought about using JMS 
for this approach.
Someone else (Ulf Schroeter) already recommended using web services. 
Seems it will be easier to find a "ready" solution (library) to do web 
service calls from our "old" app.
So I think I will give this a try.

Thanks,
   Frank

Hi Frank,

i currently have a client who is trying to implement this via SLSB and 
native library calls. Not the recommended way, but it works to some 
degree ;-)

The problem here is that the C MQ is communicating (in the Prod 
systems) via SHMem and so there is no JMS lib for the interface.

We are thinking about implementing a JCA, if it is worth the efforts 
and/or use simple POJOs as a Service Locator/Builder and expose them 
via JBoss.net. In this case it is a MQSeries (beware of the 
bit-transparency) Command and Oracle Feedback scenerio.

Going the two folded way: feed command one way via a POJO Singleton 
Command Wallpaper Pattern :) and beeing notified via DB triggered MDBs.

IMHO it depends mostly on the legacy arch there 
performance/scalability parameters and the 'standard' api which they 
expose, but is always handmade and homebrewn.

Any further details avail or are they secret? :)

[JBoss-user] JBoss 3.2.3 and Oracle 9iR2

[Langelage, Frank]

I recently switched my database from informix to oracle and encountered 
some problems.

With informix, you have one instance and many separate databases. Each 
datasource connects to exactly one database.
With oracle you have one instance and database objects per user. You 
connect to the whole instance.

I use the feature of jboss to build database tables on deployment, if 
they don't exist.
With oracle DB I got messages that some tables already exist.
But this table exist for another user (schema), not for the jboss user.

This leads to exceptions (Table does not exist) when an foreign key 
constraint to this supposedly existing table.

Shouldn't jboss use the username of oracle-ds.xml as schema for metadata 
access ?
If I set schema to "jboss" instead of null in SQLUtil.tableExists(), the 
deployment and table creation works fine.

Regards
Frank

Re: [JBoss-user] JVM Crashed while starting Jboss3.2 on solaris

category : j2ee

subcategory : other
type : bug
synopsis : JVM crashed Function name=JVM_NewInstanceFromConstructor
description : FULL PRODUCT VERSION :
java version "1.3.1_02"

This is not a problem of jboss but of your JDK or OS.
So you should upgrade your JDK to 1.3.1_09 or JDK 1.4.2_01. I'm using 
1.4.2_01 and have never seen such errors.
Perhaps you also may update your OS with current patches. The JDK uses 
dynamic libraries at runtime which sometimes have errors. Look for 
PatchPro at sun.com for this task.

You'll find a file named hsqldb-jdbc2-service.xml in 
$JBOSS_HOME/server//deploy/jms.
If you want to use mysql I'd recommend to
- rename this file to mysql-jdbc2-service.xml
- possibly replace the datasource name DefaultDS with your name (line 56)
- create the tables jms_messages and jms_transactions by hand. Look for 
CREATE_MEESAGE_TABLE and CREATE_TX_TABLE

If everything was correct, you will not see the error messages again.

I've no problems with JBoss 3.2.2RC3 on Solaris 9 (08/03) and J2SE 1.4.2 
on SunBlade 150.
I would advise you to use the newest JDK (1.4.2) and be up to date with

Hi,
I am running "JBoss3.2.2RC2_Jetty4.2.11" on my Solaris 5.8
workstation and
the jboss installation is mounted
on NFS.
Now I connect to 2 machines and try running JBoss from these
machines.JBoss
comes up fine in both the machines.
I am also running "Mod-jk2_2.0.47" as load-balancer in
Apapche 2.0.47.The
http requests are forwarded by this
load balancer to my 2 Jboss servers.
As soon as I make a web-invocation , a core dump happens in
one of the JBoss
instance.
Can we run JBoss from the same directory but from different
machines,as it
happens quite often?
I am pasting the "core-dump" from the log file generated by JBoss:

[JBoss-user] tomcat instead of jetty: where is my Servlet ?

[Langelage, Frank]

Some days ago, the servlet engine was changed from jetty to tomcat in 
JBoss-3.2.2RC2.

Today I tried to access my servlet, but I could not find it.
With jetty I could acces it with 
"http://localhost:8080/mbi4/servlet/LoadDataServlet";.

What is the correct URL now ?

Re: [JBoss-user] massive performance decrease

[Langelage, Frank]

Today I executed my little performance test with current cvs-versions of 
3.2 and HEAD.
The execution time for this testcase dropped to ~ 60 min with HEAD: a 
significant improvement.
But the execution time with 3.2RC5 is even better: ~ 50 min.

So I will take your suggestion and use 3.2 for now.

Other data loads which also create beans with CMR work well or even

Subject: [JBoss-user] default JNDI location for entity beans
Date: Fri, 21 Mar 2003 10:15:17 -0800
I have a service locator class that tries to find my Message entity 
bean. (Note the name of this bean is 'Message', but it really is an 
entity bean, not a Message Driven Bean.  It will store email messages.)

try{
_context = (Context) new 
InitialContext().lookup("java:comp/env/ejb");
_messageLocalHome = (MessageLocalHome) 
_context.lookup("Message");
}catch(NamingException ned){
_systemLogger.error("Couldn't initialize all of the

ned.getMessage());
}

On the console I see this:

 09:41:03,404 ERROR [system] Couldn't initialize all of the business 
objects: ejb not bound

Is there anything special I have to do to place my bean at a certain 
place in JNDI?  I'm using xdoclet to generate jboss.xml and 
jbosscmp-jdbc.xml.  Here's what I have in my MessageBean class.

/**

I thought that the default location was "java:com/env/ejb".  Is 
there another value I should use in the call to 
InitialContext().lookup()?

Re: [JBoss-user] Out of Memory Exception

[Langelage, Frank]

Hi Michael,

how much memory did you jboss allow to allocate ?
By default, the JVM is able to allocate 64 MB before getting "Out of 
memory exception".
You may set environment variable "JAVA_OPTS" to "-Xms256m -Xmx256m" e.g. 
for allocating a maximum of 256 MB.

Re: [JBoss-user] How to do a 'like' search using CMP in entity beans?

[Langelage, Frank]

Carsten Hammer wrote:

Hi,
I want to implement a search for all names that begin with 'Sm'.
Monson-Haefel claims this is impossible using EJB QL on a CMP field.
What does this mean?
It seems to be easy to build queries with a fixed pattern like

SELECT OBJECT(c) FROM Customer c WHERE c.lastName LIKE '%-%'

But how to do it if the pattern should be '%%'
where  is something that I catch from the 
GUI of my client application?

Thanks in advance,
Carsten 


You have to use a JBoss specific extension called JBoss-QL in this case.
In my AddressBean I declare a ejb.finder with a constant expression 
after like and use a jboss.query with a placeholder instead.
XDoclet generates the query in ejb-jar.xml and in jbosscmp-jdbc.xml.

* @ejb.finder  signature="java.util.Collection findByMatchcode( 
java.lang.String matchcode )"
*   view-type="local"
*   query="SELECT OBJECT(o) FROM Address AS o WHERE o.matchcode LIKE 
'SIEMENS%'"
*   result-type-mapping="Local"
* @jboss.query signature="java.util.Collection findByMatchcode( 
java.lang.String matchcode )"
*   query="SELECT OBJECT(o) FROM Address AS o WHERE o.matchcode LIKE ?1 
ORDER BY o.id"

Yes, EntityBeans methods are called from a SessionBeans with BMT within

Subject: [JBoss-user] JBoss-HEAD: No tx support found for method: 


Hi All,

since cvs-update last weekend I get this warning for every method call 
on my entity beans.
But all bean transcations are CMT with transaction attribute Required.
 

I 
   

checked this in ejb-jar.xml.
I use XDoclet-1.2b2 for creating deployment descriptors.
Even setting transaction atribute on method level does not solve this 
problem.

Anybody else out there who gets the same problem now ?
Any solution for this ?

   Frank

[JBoss-user] Problem with Query containing LIKE

[Langelage, Frank]

Hi All,

I want to search addresses by matchcode with wildcards.
So I declared a finder like this:

* @ejb.finder  signature="java.util.Collection findByMatchcode( 
java.lang.String matchcode )"
*   view-type="local"
*   query="SELECT OBJECT(o) FROM Address AS o WHERE o.matchcode LIKE ?1"
*   result-type-mapping="Local"

From SessionBean I want to call "...findByMatchcode( "SIEMENS%" )" e.g.

On deployment of the EntityBean I get an exception.
The EJBQLCompiler JBoss4 doesn't like this. It wants a STRING_LITERAL 
after LIKE.

How do I have to modify the query to get what I want.
Or is this not possible ?


Regards
   Frank

[JBoss-user] Using CMR with PK-Field as FK

[Langelage, Frank]

I have two beans Feature and FeatureOption with CMR.
JBoss-HEAD created the tables correct, using the new feature to have the 
same field as FK to parent and part of PK:
   create table feature ( feature_id smallint not null,  description 
varchar(30),  primary key (feature_id)  constraint pk_feature );
   create table feature_option ( feature_id smallint not null, 
option_id integer not null,  description varchar(30),  primary key 
(feature_id,option_id) constraint pk_feature_option );
   alter table feature_option add constraint (foreign key (feature_id) 
references feature  constraint fk_featur_1isvfy8);

But everytime I try to add FeatureOptions to Feature, I get an Exception:
   java.lang.IllegalStateException: CMR field Feature_options is mapped 
to a foreign key which is a part for a primary key,
   and primary key may only be set once in ejbCreate [EJB 2.0 Spec.10.3.5].

My code looks like this:
feature = featureHome.create( feature_id, description );
coll = feature.getOptions();
featureOption = featureOptionHome.create( feature_id, option_id, 
description );
coll.add( featureOption ); // this line throws the exception.

So my Question is: How to add a FeatureOption to Feature ?

Re: [JBoss-user] Question about CMP/CMR

[Langelage, Frank]

Hallo Alex,

I know you ported this feature not long ago from HEAD to 3.2.

I use HEAD here and use this new feature for Bean2, if I understand it 
right.
Column festr.festa_serial is part of the primary key for festr and also 
foreign key for festr referencing festa.festa_serial.

But if the foreign key field is not part of the primary key, like in 
Bean3 (febdr), the foreign key field must not be CMP-Field in the bean. 
It's automatically added because of CMR.

As said, I would like jboss to recognize that the field already exists 
also in case of Bean3 and use this field for CMR.


Frank

Hello Frank,

in JBoss-3.2 (cvs version) you can map foreign key fields to primary
key fields. This is done by specifying the same column names for
foreign and primary key fields.

[JBoss-user] Question about CMP/CMR

[Langelage, Frank]

JBoss-Head, JDK 1.4.1, Informix-DB

Following given situation:
Bean 1:
Name=Festa, DBTable=festa, PK=festa_serial
Bean 2:
Name=Festr, DBTable=festr, PK=festa_serial+festr_pos_nr, 
FK=festa_serial -> festa
Bean 3:
Name=febdr, DBTable=febdr, PK=febdr_serial, FK=festa_serial -> festa

As you can see, for bean 2 the CMR-Field festa_serial must be a 
CMP-Field, because it's part of the PK.
For bean 3 the CMR-Field festa_serial must not be a CMP-Field. Otherwise 
you get a DeploymentException because of a "wrong" 
SQL-CreateTable-Statement.
The field festa_serial is mentioned twice here.
I would like JBoss to recognize that the CMR-Field is already there as a 
CMP-Field in both cases.

So my question: Is this a Bug, a FeatureRequest or a must be which will 
not be changed ?

The default transaction-timeout is 300 sec, defined in

You may increase this value or use a UserTransaction.

Re: [JBoss-user] Programmatic Transaction Timeouts?

Hi All,

For the most part, the default transaction timeout of 5 minutes is 
reasonable for my application. However there is one operation that 
the server needs to perform that, depending on the size of the files 
involved, can take 20 minutes, an hour, or more.

I'm interested in setting the transaction timeout for specific 
transactions to something much higher. Is that possible? I'm using 
JBoss 3.0.3, not using Tyrex, and Jetty for the web container.

Thanks for any advice.

-Neal
 

You can use a UserTransaction and set the TransactionTimeout:

   javax.transaction.UserTransaction trans;
   :
trans = (javax.transaction.UserTransaction)ctx.lookup( 
"UserTransaction" );
trans.begin();
trans.setTransactionTimeout( 86400 );
   :
   :
   if ( error )
   trans.rollback();
   else
   trans.commit();
