RE: [JBoss-user] Higher Level Docs?
Eric, Have you seen the quick start guide for 3.0? It's on the SF DL page @ http://prdownloads.sourceforge.net/jboss/JBoss.3.0QuickStart.pdf?download Some of this stuff is there. There is also some (though some "low level") at the volunteer HTML docs, which may be what you are taling about. OW, go ahead and post questions here.

[JBoss-user] RE: [JBoss-dev] Open-Source Fight Flares At Pentagon
They are so cute when they try to convince the world their platforms are more secure I thought I'd share my favorites: "I've never seen a systematic study that showed open source to be more secure," said Dorothy Denning, a professor of computer science at Georgetown University who specializes in information warfare. --- Is there a systematic study that says they were less secure??? What a bozo statement. "Microsoft's push is a new front in a long-running company assault on the open-source movement, which company officials have called "a cancer" and un-American." un-American? In the sense that "American" means anything MS profits from, I guess. a Cancer? No wonder I feel dirty. I liken those f&%^#ing macro viruses more to a cancer than anything else. "Microsoft also said open-source software is inherently less secure because the code is available for the world to examine for flaws, making it possible for hackers or criminals to exploit them. Proprietary software, the company argued, is more secure because of its closed nature." Hmm. If they say it, it must be true. Just more FUD-rhetoric. Nevermind that there are (I would argue) FAR more well-meaning folks testing OSS software than ill-meaning ones. #mike -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Scott M Stark Sent: Thursday, May 23, 2002 1:45 PM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: [JBoss-dev] Open-Source Fight Flares At Pentagon Microsoft tries to squelch Open Source at the pentagon, but apparently many at the pentagon are seeing the light. http://www.washingtonpost.com/wp-dyn/articles/A60050-2002May22.html ___ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas -- http://devcon.sprintpcs.com/adp/index.cfm ___ Jboss-development mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-development ___ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas -- http://devcon.sprintpcs.com/adp/index.cfm ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user
RE: [JBoss-user] JBoss in a multi developers environment
Emerson, There is no simple way to do such a setup. You'll have to go in and mod the various files for the port changes. To help keep track of ports, we add some increment of 100 to the default port numbers for each developer (8080 > 8180, 8082 > 8182, etc). Kinda lame, but it works Anyone out there tried setting up virtual network interfaces (/dev/hme0:1, etc) to get around the port conflict problem? Seems like it should work, provided you can set the 'listen' address on all the services (which still means mucking with all the config files, huh). Lastly, FYI, there was a thread on jboss-dev a few weeks back regarding this and how to make it less painful (server automatically finds open ports). I have been working on a solution (based on 3.0), but am working through some issues with it (not the least of which is time :-) ).

[JBoss-user] RE: jdbc block size in jboss
Eric, I didn't think JDBC spec'd a block size/fetch size property (don't recall it being in the spec). If memory serves, DB2 has such a beast, but I was never able to find anything in the Oracle or Sybase JDBC docs about it. That said, in JDBC 2 (maybe 2.1?), there is a setFetchSize() on the statement interface, but I believe vendors can ignore it. Maybe one of the JBoss CMP guys out there can confirm? Maybe it's known as something besides block size? Typically, in Oracle, block size has a whole different meaning.

RE: [JBoss-user] RC2 deploy probs
OK - makes perfect sense. I was thinking in the old db-connection-loginId-shared-by-everyone model. BTW - I just noticed (by accident) that if in login-config.xml realm, you point at an MCF name that does not exist, JBoss goes CPU bound and consumes memory like a wild man (up to 400-500 MB RAM).

When the pool starts it doesn't know who is logging in. When it gets a Subject from the first request, it makes the rest of the connections up to minSize using that Subject in a separate thread. (Actually using Subject and ConnectionRequestInfo). If you are using something like CallerIdentityLoginModule, so you are getting connections for many different subjects, note that (depending on the Criteria property of the pool) you will get many separate pools, one for each Subject. Each one gets the minSize and maxSize you set. So far I haven't tried to implement a global maxsize with borrowing from one sub-pool to another.

*3.0* RC2, that is. I have a datasource (Oracle) service file and related security realm that deploy fine in RC1. In RC2 neither appears to be bound to JNDI.

Does this ear file use JAAS? I wouldn't think you would see this unless the container was loading JAAS to satisfy some security constraint. Mine doesn't. Looks like auth.conf stuff is now in login-config.xml (as of RC1?). And, in login-config.xml, the 'other' (ie the default) security domain is set up to use UsersRolesLoginModule, which reads users.properties and roles.properties.

Yes, it does seem strange which is why I am assuming there is something more

I don't know about server restarts either. As an experiment I let my session
bean be passivated with a reference to an EB, and it did activate properly.
However, this is not what we are supposed to do if we need to pass a
reference out to a remote (beyond of app server) client. That is why I was
using handles. My thinking is that the wrapper class (which holds the EB
reference) shouldn't have to care if it was being used by another EJB in the
same app server or being sent far, far, away. It should do the same thing no
matter what. (I hope I can figure out how to achieve this in practice).

I implemented it in the wrapper classes for the EBs. I understood (and
still believe) that I should pass EB handles to remote clients, and not the
reference to EJBObject. Passing the remote interface is useless because it
does not identify a specific EB ie. one associated with its primary key. My
client via its SFSB asks for acess to an EB, but it is the SFSB that figures
out which EB the client should access based on its state. So the SFSB must
pass back a specific reference, not just an interface.
Its the wrapper around this EB reference that uses readObject() and
writeObject(). The wrapper instance holds a reference to a specific EB but
can't let itself be serialized with this reference - because it does not know
where it will be deserialized it must swap the reference to the EB with its
handle and let the handle be serialized instead - ala writeObject(). Upon
deserialization it uses readObject to get the handle and then convert it back
to a proper EB reference wake-up.
Here an example from one of my wrappers (about 12 lines):
private transient CachedRecordSet crs;
-- other non transient fields omitted --
-- business logic omitted --
private void writeObject(java.io.ObjectOutputStream out)
throws IOException
{
out.defaultWriteObject();
Handle handle = bean.getHandle();
out.writeObject(handle);
}
private void readObject(java.io.ObjectInputStream in)
throws IOException, ClassNotFoundException
{
in.defaultReadObject();
Handle handle = (Handle) in.readObject();
bean = (CachedRecordSet)
javax.rmi.PortableRemoteObject.narrow(handle.getEJBObject(),
CachedRecordSet.class);
}

Yes.

Yes. But, by testing, only if the utility's reference was serialized NOT
using a handle (ie do nothing, or use the home/pk substitution).

Yes. When passing to a remote client I can use handles, but when using it
with a local client, as with a SFSB in same application, I seem to have to
make sure that if the SFSB gets passivated that it does NOT use handles.
So when being serialized it seems that the bean referene needs to know why
its being serialized so that it can choose the correct serialized format !!
And IMHO that sucks.
> I hope that helps
Yes. Although I don't think the problem is solved, in the short run I can
make it work, and that puts me far ahead of where I was a few days ago.

Th
Re: [JBoss-user] SB timeout -> passivation -> activation failure
> I have never tried serializing an object by explicitly calling readObject() > and writeObject() on a serializable. Does that work? Yes. During serialization these methods will get called to allow a class to control its own serialization process (mostly for transient fields). I am using them when serializable classes (bean or otherwise) have references to beans. These classes hold their bean references in transient fields and during serialization I write out either the handle, or now the home/pk pair. > Is there a reason why you were using the EJB handle?

Okay. I use a utility class to wrap all access to entity beans, this is used to localize lookup and exception handling. Any class (bean or otherwise) that wants access to an EB uses its utility class. So my SFSB gets an instance of the utility class and the utility class holds the reference to the EB in a transient variable. As well the SFSB may pass to the remote client a copy of the utility class so that it can directly access some EB services independent of its 'session'. I read somewhere (can't recall just now) that I was to use the handle, so that was what I was doing. But after resolving the passivation/activation yesterday, I have changed all my wrapper classes to use home/pk. I wish I better understood what was happening with these various types of references so I could know precisely which type to use under which circumstances. I am pretty confused. And you have suggested that for in server references (those held directly or indirectly by beans) that I shouln't have to do anything, the server will take care of it --frustrated sigh. And what if the reference was from a servlet/jsp when the web container is running in the save VM. Would it still be taken care of? Would you happen to know a reference/tutorial that distinguishes and contrasts each of the reference types and explains when and how to use them apppropriately?

Re: [JBoss-user] SB timeout -> passivation -> activation failure
> Passivation should definitely not kill a stateful session bean. > (Does JBoss do this?) No. It seems that it was (as you suggested) a problem with serialization of references that my stateful SB was holding (albeit somewhat indiretly) to entity beans. The last comments Burkhard and you made were the missing link that I needed. Thanks to Michael, yourself, and Burkhard for the help. I greatly appreciate it. But, humour me please... two related questions... Q1 When I checked what was happening during passivation of the SFSB I was using readObject() and writeObject() to serialize the handles of of any referenced entity beans. A handle was obtained from an EB's remote interfaces via EJBObject.getHandle(). The fix was to instead serialize both an EB's home and primary key via EJBObject.getEJBHome() and EJBObject.getPrimaryKey(). Why does this work? I thought that we were supposed to use the handle to pass EB references around. What exactly should be saved to properly and portably restore the EB reference? And does it make a difference if the reference is being passed to a real remote client instead of another bean (I would hope not)? Q2 So JBoss is correctly passivating SFSBs once the is reached, and will activate them correctly (if I don't screw it up) when later needed. How then does JBoss know when to finally kill off a bean (eg. where the client has died)? Is there a way to configure this?

Re: [JBoss-user] SB timeout -> passivation -> activation failure
Okay, maybe I'm being daft - but I just don't get it. from the manual specifies the max age a bean can have before being passivated by the overager ... the specifies the period of the resizer, that is a periodic task that runs ... Purpose of this periodic task is to shrink / enlarge the cache capacity upon 3 other parameters... So after 10 minutes of inactivity (jboss's default of 600 secs) it should be passivated --not destroyed. Shouldn't I be able to continue to use the bean at 12 minutes (upon which the server will de-passify the bean ie. activate it) without the client ever being aware? And if is for passivation where do I specify the ultimate time after which a very old inactive bean (passivated or not) should actually be destroyed (eg. dropped connections)? Currently it seems that the is acting as a destroyer and not a passivator. Is this understanding correct? Thanks for continuing to help. Mike. P.S. As an aside I would have thought that using a min cache size (jboss's defalut is 50) greater than the number of active beans (3 in my development setup) that there would be no passivation at all. As there is still room in the cache why why would jboss push out any bean (except of course those that should be killed -- but they should be killed and not passivated anyways)?

Burkhard Maybe a bit more info will help. I am building the server side with EJB's because I very much like the promise of putting business login in a middle tier (in this case an enterprise java app server ie JBoss). Phase one of my project is to build a somewhat traditional client app (Swing in this case) that uses the services of the app server instead of the 2-tier model which invariably would result in some business logic in the client app (yuck - been doing that for far too long). So an office worker using the app needs to authenticate once in the morning and have access all day long... ie. a long stateful session. Passivation is okay (in fact fantastic) but only if (re)activation works. Phase two of the project is to open up access up to business partners and customers via web or tiny-apps. These will also use session beans (hopefully the same one as the former) but will be much shorter lived. So, I am happy to change the bean aging, and even clone the bean so that I can have one that is short-lived and one that is long-lived but the long lived one must be able to be able to survive multiple passivation-activation cyctes until it is cleanly terminated by the client or a suitably long (in the order of hours) timeout occurs. Right now it seems once passivation occurs on the stateful bean the session dissapears into a black hole, and when the server tries to activate it it blows. Surely this is not correct behaviour on part of the server? And this is what I am trying to fix. Sorry for the long winded answer but figured more was better than not enough.

[JBoss-user] SB timeout -> passivation -> activation failure
If I let a 'connected' client sit around for more than apporx 20 minutes it blows on its next attempt to use a remote method of the SessionBean (only the one session appears to be blown, since I can start a new client session without restarting the server). What I want is to be able to have the client's session stay alive for a very long time (12-15 hours total) and be able to survive 2-3 hours of inactivity. It seems (from the messages below) that my sessions cannot be restored once passivated. Is this a timeout/activation problem that can be fixed by changing my configuration?

This is an EJB question (not really JBoss specific)... I have a entity (cmp) bean which is just a simple sequence number generator. Its one fancy feature is that with each request it blocks-off a series of numbers for the client. What I am trying to do is wrap the access to the entity bean in a utility class (SequenceHolder) which simply returns the next sequence number from the block that it got from the entity bean. When it has used up all that were in the block it will request a new block from the entity bean. This should greatly reduce the number of accesses to the entity bean at the cost of some skipped/wasted numbers. In general this is simple enough - but I want the same utility class to be able to be used on the server (as a utility to other EJB's) and on the client. How do I go about setting up the state of SequenceHolder so that a) its access to the entity bean will work from both the server and the client b) it can be created on the server and serialized back to the client? I know this is general EJB stuff, but at my current level it seems quite tricky, and I still have a muddy (at best) understanding of the allowed uses of bean/home/remote references after all the book/docs I've read. Any help, examples, or RTFM's are appreciated! Thanks in advance Mike. === Mike Finn Tactical Executive Systems [EMAIL PROTECTED] ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user
[JBoss-user] Transactions - Container Managed
I am having a problem with rolling back a container managed transaction.
Here is the scenario...
Stateful bean(name = gb/dbSession)
calls
CMP entity bean (name = gb/sequence).
Both are deployed in same jar file with the transaction attribute set to
"Required". In order to test transactions I put a ctx.setRollbackOnly()
call in the session bean before it returns. I expected that the changed data
in the entity bean would be tossed (ie not saved to the datastore) as the
whole transaction would be rolled back. But not only was the data committed
to the database (postresql if it helps) but a call to ctx.getRollbackOnly()
just prior to and just after the ctx.setRollbackOnly() returned true both
times. What gives?
A further heavy handed approach was to force a runtime exception (a divide by
zero which is commented out in the code below) in the session bean and see if
that would rollback the transaction... but no success. I don't get it.
One possibility was that the
org.opentools.minerva.jdbc.xa.wrapper.XADataSourceImpl was not turning off
the JDBC autocommit, but a check of the code ruled that out. So I am
stumped.
Help please.
Thanks.

Re: [JBoss-user] JNDI Naming for references
Thanks to Vladimir, and Åsmund. I feel a bit daft (>6 hours) since it was just a leading "/" problem in the end "java:/comp/env/..." vs "java:comp/env/...". Just as the manual had said. One more question though... When rereading the chapter (very, very carefully this time) it says that the narrow operation is not required after looking up the home interface when using JBoss. Every book that I have read though says it should be there. Is this a JBoss specific thing? Or all all containers likely to move in this direction? Thanks again. ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user
