Excellent. I'm glad I put that little bit of information there. It's 
always good to solve these things.

Cheers.

Re: [JBoss-user] Jetty SSL with 3.2.0RC2

[Frank Morton]

Thanks! You were a huge help. I missed the obvious and was changing
the jboss-service.xml in server/default/conf instead of the one in
server/default/deploy/jbossweb.sar/META-INF. Worked first time
after that.
Your other info was also helpful.

Hey Frank, it really looks good, but just in case it's helpful, here's
the contents of my jboss-service.xml in
server/default/deploy/jbossweb.sar/META-INF which works with JDK

Now, I added NeedClientAuth because I was experimenting with the
requirement of having SSL client certificates to access this SSL port
(which works for anyone who cares), you don't need that. The only
other difference is the way I'm setting the Keystore property. It'll
basically do the same thing as yours.
The only other thing that you really need to ensure is that your
keystore file actually exists and is a correct JKS keystore. I
created mine with a command very similar to the following:
keytool -genkey -alias myalias -keyalg rsa -keysize 2048 -validity 365
-keystore mykeystore.jks -storepass MyPassword -keypass MyPassword
Then typed in the answer to the rest of the questions. It doesn't seem
to matter what 'alias' you use, I'd guess it probably tries the first
alias it finds which has a private key. It seems to settle on the
first certificate in alphabetical order. If you have more than one
key in your keystore, you may need to make a new keystore with only
the keys you want. The keysize is also not important, 1024 also works
fine. I'd use at least 1024 bits though. I think you definitely need
a keyalg of 'rsa' for this to work at all. I tried using 'dsa' (which
is the default algorithm it seems) and it wouldn't work. Also, by
default, it seems that keytool generates a self-signed certificate
which is all that's needed to get an initial SSL test working.
A semi-interesting fact about getting SSL client certificate
authentication working is this: The client certificates must be
created by a trusted certificate authority. This means that your
keystore file must contain the public certificates of the certificate
authority your SSL server should trust. Without this the client
cannot prove it is trusted by any CA the server knows about, and the
client is rejected. That's just an aside, but useful info to someone
trying to get client auth working.
In your server logs you should see lines like the following if it's
working:

[JBoss-user] unknown-pk and doc type jboss3.2RC3

[Dennis R. Gesker]

Hello All:

I seem to be experiencing a conflict between my doc type definition and 
my use of  and  tags and was wondering if it 
was a problem I'm having is with my configuration or if it is part of a 
wider issue.

Earlier today I was having some difficulty preparing a jbosscmp-jdbc.xml 
file that would allow me to to use the the  and 
 tags. After becoming a bit frustrated I moved the tags 
from within the  tags to the  tags and the EJB 
deployed just fine.

I removed  

http://www.jboss.org/j2ee/dtd/jbosscmp-jdbc_3_2.dtd";>
from the begining of the file and placed my entries (below) back inside 
the  tags and they loaded just fine.

 companyEntity
Company

   java.lang.Integer
   index
   index
   INTEGER
   SERIAL
   
  
   
 
class="org.jboss.ejb.plugins.cmp.jdbc.JDBCPkSqlCreateCommand">
SELECT 
nextval('company_index_seq')
 

Is anyone else having this problem? Is the above doc type the correct 
one for use with this version of jboss? (I copied it from the 
jbosscmp-jdbc_3_2 file under /docs/dtd)

Thanks,
Dennis

  Returning to my prevoius postings, assume we have Partner and

  2) One Partner owns Many StoreCategories 
  The following ejbql: 
  SELECT DISTINCT OBJECT(c) FROM StoreCategory c, Partner 
  p   WHERE c.browsable   AND (c.partnerOwner.id=?1 OR (p.id=?1 AND p MEMBER OF

  results in:

Okay, just discovered [EMAIL PROTECTED]; unfortunately the error messages

a bad value for xmbean-dd, so it is being read at some point).

So lets blame the generated file:

The number of keywords in the database.
Count

Any ideas what could be missing here?

Re: [JBoss-user] Performance estimation

[Dan Christopherson]

Unfortunately, a lot of this depends on how you design your application, 
and a few configuration options for JBoss. It shouldn't be much of a 
problem if you have plenty of memory (and allow the JVM to use it via 
-xmx flag), and use Commit option A on all entities. CMP2 with 
read-ahead will be more efficient than BMP. If you don't use entity 
beans, or if you don't use commit option A, you'll be serializing stuff 
out of the database as its needed in each transaction. This will give 
you very much higher latencies.

Having said that, 5TX/second isn't much load, really. Having 200 
concurrent users is more of a memory issue than anything - how much of 
an issue depends on how much data you keep in HTTP sessions and stateful 
session beans.

Hi,
You 
could use http session to store instance of the session bean. Something like 
following:
<%
    
MyStatelessSession theBean = (MyStatelessSession) 
session.getAttribute(“theBean”);
    
If (null == theBean) {
    
// create the instance
    
session.setAttribute(“theBean”, theBean);
    
}
    
// use the bean.
%>
 
This 
way the instance of the bean will be created once per 
session.
 
Of 
course you may look at some design patterns too, for example business 
delegate pattern (a good example can be found in “Programming Jakarta 
Struts” by Chuck Cavaness ).
 
Hope 
this helps.

stateless session bean access from servlets
 

Hi all,

 

My business logic is controlled 
by stateless session beans.

My front-end is probably going 
to be JSPs which use the session 

beans. I could create a 
reference to the session bean each time it's 

used, but from my understanding 
of how it works, when the client 

calls 
MyStatelessSessionHome.create( ) we cannot tell if a new object 


is actually created on the 
server. 

 

My understanding is that 
the container can at any time decide which 

instance of the stateless 
session bean in the bean pool can be used for 

the client's reference. So, my 
question is - would it not be more optimal 

to actually create a reference 
to each of my stateless session beans on 

the main servlet startup (say in 
init) and let each of my jsps use the same 

reference. This would avoid the 
overhead of bean creation for each JSP. 

 

Thoughts,

cheers,

Brian

Hello all,

Can somebody suggest me, how many processors and memory will we need
? Has somebody experience with that or largest system ?

Hi Vladimir.

This would translate as a minimal load.

When I was first proof of concept testing JBoss 3.0, on a laptop no less,
I had it supporting just over 200 users, running about 5TX/second (double your
requirement).
Laptop was a Sony Viao, 850Mhz PIII 256MB Ram (PC100Mhz).
OS was SuSE Linux (7.1 at the time - they have since put out a few upgrades,
I would recommend 8.1 today).
JVM was Sun's JDK 1.3.1.
You may be interested to note the following;
1) Laptop running in Graphical Mode (I was running this test in KDE)
2) Somewhere between 205 - 210 concurrent users, ran out of Ram and
started swapping, which completely destroyed performance.
The project in question was designed to initially support 145,000
concurrent users, with approx 15,000 Tx/sec.

[JBoss-user] Oracle RAQ Plus thick driver memory issues.

[jbossuserlist]

I have an issue in our production environment we have JBOSS 3.03 running off redhat 
7.3 and 
an Oracle RAQ database cluster with transparent fault tolerence and high availability.
My problem is that these Oracle RAQ features require the use of the Oracle OCI (Thick) 
driver.
As a result our memory foot print has grown alarmingly.
For a JVM size of 300MB the JBOSS App Server uses 3GB or so.
Can anybody suggest a solution or cause for this.

What triggers the trigger? Can you not create a stateless session bean that uses JDBC 
to read/write to the database and sends JMS messages? If you (properly ;-) did that, 
EJB container would automatically coordinate transactions between JDBC and JMS. I 
though that was the whole point on EJBs.

Sorry, I did not understand you were talking about using RA directly from the client. 
I might be wrong but I do not think JBoss currently supports "non-managed" part of the 
JCA spec. Can you explain in more details what you are doing and why do you need 
access to "raw" connection factory?

Igor.

RE: [JBoss-user] Optimise stateless session bean access from servlets

[Stas Krichevsky]

Hi,

Re. #1 – Probably you’re
right, but we’re doing it in our product and till now everything worked. If
the reference becomes bad, you can catch the exception and re-create the
reference.

Re. #2 – Sure, you can use try/catch
blocks in jsp.

Re. #3 – The difference between statefull
and stateless beans is that in stateless bean you should pass the “state”
to every bean method, i.e. container may give the same bean instance to
different clients.

 

Again, what I suggested was only
performance optimization and if you didn’t decide yet on the architecture
of your product, it’s better to look at some mvc framework and some
design patterns first.

Hi,

You could use http
session to store instance of the session bean. Something like following:

<%

   
MyStatelessSession theBean = (MyStatelessSession)
session.getAttribute(“theBean”);

   
If (null == theBean) {

   
// create the instance

   
session.setAttribute(“theBean”, theBean);

   
}

   
// use the bean.

%>

 

This way the instance of
the bean will be created once per session.

 

Of course you may look at
some design patterns too, for example business delegate pattern (a good example
can be found in “Programming Jakarta Struts” by Chuck Cavaness ).

 

Hope this helps.

[JBoss-user] Jetty SSL with 3.2.0RC2

255
5
2000
/usr/local/jboss/server/default/conf/keystore
mypwurd

Nothing is listening on port 8443 at all. This appears to be ignored. 
Ultimately,
I want to configure this on a production 3.0.6 server, too. So, if 
there are differences
in configuring the different versions, please let me know.

Anyone else have this running that can tell me what is missing or wrong?

[JBoss-user] finders across a relationship

[Ionel Gardais]

Hi,

Say an M:N relationship, maintained by a table-relation, between Person 
and Drink.

Is it possible to create a finder in the Drink bean that takes the name 
of a Person as arguments and returns a Collection of the Drink 
associated with the Person's name ? (Or a finder in the Person bean 
which takes the name of a Drink and returns a Collection of Person who 
have this Drink in their list)

Thanks,
ionel

[Felipe Oliveira]

Hi Stefan,

Thanks for your help. Jetty's documentation is not very good at all but 
they do have an active mailing list. Somebody pointed me the right 
direction. There's an extended parameter on 
jbossweb.sar/META-INF/jboss-service.xml you can just set to true.

Sorry I not know where, but I know that it is possible.
Had you take a look in the jetty documentation? I'm really not sure but may
be it was related to log4j.

RE: [JBoss-user] Optimise stateless session bean access from servlets

[Stas Krichevsky]

Hi,

You could use http session to store
instance of the session bean. Something like following:

<%

    MyStatelessSession
theBean = (MyStatelessSession) session.getAttribute(“theBean”);

    If
(null == theBean) {

    //
create the instance

    session.setAttribute(“theBean”,
theBean);

    }

    //
use the bean.

%>

 

This way the instance of the bean will be
created once per session.

 

Of course you may look at some design
patterns too, for example business delegate pattern (a good example can be
found in “Programming Jakarta Struts” by Chuck Cavaness ).

 

Hope this helps.

stateless session bean access from servlets

 



Hi all,





 





My business logic is controlled by
stateless session beans.





My front-end is probably going to be
JSPs which use the session 





beans. I could create a reference to
the session bean each time it's 





used, but from my understanding of
how it works, when the client 





calls MyStatelessSessionHome.create(
) we cannot tell if a new object 





is actually created on the server. 





 





My understanding is that the
container can at any time decide which 





instance of the stateless
session bean in the bean pool can be used for 





the client's reference. So, my
question is - would it not be more optimal 





to actually create a reference to
each of my stateless session beans on 





the main servlet startup (say in
init) and let each of my jsps use the same 





reference. This would avoid the
overhead of bean creation for each JSP. 





 





Thoughts,





cheers,





Brian

Absolutely not.  Don't try to  write your own TransactionManager.  If your
program is written as (session) ejbs, I recommend using container managed
transactions.  If it is a servlet or mbean or you found some other exotic
way to run code inside jboss, use UserTransaction to control your
transactions.

You should be able to use 3.0.7 from cvs also, but your life will be
simpler if you use 3.2RC2 or later and the *-ds.xml config file.

[JBoss-user] EJBQL MEMBER OF problems remain in 3.0.6?

[Alexey Yudichev]

Title: EJBQL MEMBER OF problems remain in 3.0.6?





Returning to my prevoius postings, assume we have Partner and StoreCategory entities with TWO relations between each other:

1) Many Partners are assigned to Many StoreCategories
2) One Partner owns Many StoreCategories


The following ejbql:


SELECT DISTINCT OBJECT(c) FROM StoreCategory c, Partner p
  WHERE c.browsable
  AND (c.partnerOwner.id=?1 OR (p.id=?1 AND p MEMBER OF c.partners))


results in:


SELECT DISTINCT t0_c.id FROM storecategory t0_c, partner t2_p, partner t1_c_partnerOwner WHERE (t0_c.browsable AND (t1_c_partnerOwner.id = ? OR (t2_p.id = ? AND EXISTS (SELECT t4_c_partners_RELATION_TABLE.Partner FROM partner_categories_stor_1cl2gdd t4_c_partners_RELATION_TABLE WHERE t0_c.id=t4_c_partners_RELATION_TABLE.StoreCategory AND t2_p.id=t4_c_partners_RELATION_TABLE.Partner AND (t0_c.partnerOwner=t1_c_partnerOwner.id)

c.partners is m2m cmr, c.partnerOwner is o2m cmr.


We can see that the last clause "AND (t0_c.partnerOwner=t1_c_partnerOwner.id)" ONLY limits result to the o2m relationship although in ejbql we have OR clause.

hi,

You can take a look on this pattern:

http://java.sun.com/blueprints/code/jps131/src/com/sun/j2ee/blueprints/servicelocator/web/ServiceLocator.java.html

all called local or remote interfaces will be cached.

[JBoss-user] Latest quickStartGuide flaws - web integration

[Joao Pedro Clemente]

I've just checked the latest quickstartguid and notist3d the web
integration chapter has several gflaws:

jetty-plugin.sar is mentioned all over the chapter, where there is none in
real life (now it's jbossweb.sar)

the jboss-service.xml doen not match

it's said that you can use a ROOT.war file to deploy to "/", where in
JBoss-Jetty faq they say the opposite.

Btw, ehn this gets right, will it be available at cvs or do we need to
wait for another release?
And, if it gets available at cvs, what module?

Thank you
