Re: [JBoss-user] OutOfMemoryError
Well... Memory leak in JAVA???
Hopefully no, BUT!
I have managed to get a memory leak
in the JVM :)))
Most of you know what a singletone
means :) A class, that has a static member variable pointing to the one and only
object of that class... Recently I got a class, that had a nonstatic pointer to
itself (copy of the "this"). This way the GC could not free the resources, that
were reserved for these classes. Don't know why, but that just may be a miss in
the JVM. So whenever I created an instance of that class I got it FOR LIFE.
Quite shortly the machine ran out of memory (it was a big damn
class).
So... The main (and the only I've
seen) reason for memory leaks in Java are the self pointing
objects:
public class
SelfPointer{
SelfPointer
MemoryLeaker;
public void
SelfPointerInit(){
MemoryLeaker
= this;
// If you
don't clean the MemoryLeaker to null,
// than
this class is not going to be GC-ed.
}
}
However this depends on the JVM.
Using the classic or Server JVM I think fixes the problem :)

Re: [JBoss-user] ./conf directory location
I'm glad it work with you... However... Julian Gosnell is also right to want different configurations per-user. Currently I'm in no position to try anything under any Linux (damn WinDoze). But... I see, that there is a parameter to the JBoss, that points which configuration should it use... java -server $JAXP -classpath $JBOSS_CLASSPATH org.jboss.Main $@ If there are no params JBoss uses conf default. My idea is: in the conf directory create a symbolic link for every user, that you wish to be able to run: /usr/local/JBoss/conf/user1 -> /home/user1/.jboss_conf /usr/local/JBoss/conf/user2 -> /home/user2/.jboss_conf /usr/local/JBoss/conf/user3 -> /home/user3/.jboss_conf /usr/local/JBoss/conf/root -> /tmp/some_dead_end_directory_with_no_read Then every user can configure JBoss in his .jboss_conf directory. Lastly one can create a copy of the RUN.SH script, that does something like this: java -server $JAXP -classpath $JBOSS_CLASSPATH org.jboss.Main $USER java -server $JAXP -classpath $JBOSS_CLASSPATH org.jboss.Main $USER_NAME If user1 runs this script it will run as follows: java -server $JAXP -classpath $JBOSS_CLASSPATH org.jboss.Main user1 And will get the confs from the /home/user1/.jboss_conf directory as stated by the symbolic link. Twingling with the write permissions is also a good idea. Take in mind, the read and write permissions for the files in all the conf directories. I'm writing by memory. May have some mistakes. I also can't test this!!! Please... If you can test, than DO! This is NOT a secure script... A user can set his ENVIRONMENT $USER to root and run the script. Bear that in mind. Maybe this will work??? Please notify me, if this method does the job. May the shade of the tree strengthen you all...

[JBoss-user] Connection problem
Hello, What happens when a session bean uses a database connection, it gets the connection from a connection pool, creates a prepared statement, retrieves all kinds of things, closes the prepared statement and returns. In other words, the session bean does not close the connection. At the moment I am facing that situation. I have a collection of jsp files, some regular Java beans acting as proxy for some ejb's. The website starts well, but after a while I get the following error message: '[NewsCollection] java.sql.SQLException: Communication link failure: java.net.SocketException' (NewsCollection is a session bean who uses a java.sql.Connection it gets from a javax.sql.DataSource. NewsCollection is the one that does not close the connection). I am pretty sure the errors are the result of never ever closing a connection. A java.sql.Connection instance does not close the connection when the local variable runs out of scope or does it? At least not when the connection originates from a connection pool.

[JBoss-user] example ant file for creating an EAR file
Hello, Besides the connection troubles mentioned in an earlier post I have one other thing on my mind. While investigating the connection problem I found out that I am not deploying my web application in a correct manner. For the record, I am using JBoss with Tomcat embedded. The deal seems to be to create one ear file and let JBoss/Tomcat sort it out. The creation of one EAR file is very confusing for me. For instance, do need to create at least two jar files? One containing only EJB's and one containing the regular java classes who act as proxy for the EJB's. And futhermore, I would like to automate the creation of the .ear file using Ant. Has anyone done that? And if so, could you give me some guidelines on how to setup the directory structure? Perhaps some Ant example code?

Re: [JBoss-user] Connection problem
Hi, You need to call close() on your connection when you are done with it. non-managed --- (connection from Driver or something like Borland/interbase/interclient non-pooled datasource) -- this closes the db connection, frees resources. managed ---(what you should be using with ejbs, for example connection from a jbosspool datasource as the front end for a pool or a jca resource adapter) -- this tells the container you are done working with the connection, the underlying db connection can be returned to the pool for reuse. david jencks On 2001.06.09 08:12:27 -0400 Marcel Schepers wrote: > Hello, > > What happens when a session bean uses a database > connection, it gets the connection from a connection pool, creates a > prepared statement, retrieves all kinds of things, closes the prepared > statement and returns.

Here is the problem... 1) I have a 'LoadOnStartup' servlet that instantiates a singleton class in it's init() method. 2) The singleton connects to a Statefull session bean using a user and password passed from the servlet. 3) The singleton has a timer which calls the session bean every 10 seconds 4) The servlet is accessed from clients with their security ids to update the singletons internal state My problem is that the singleton looses its authentication after the first timer event...

[JBoss-user] RE: jboss wiki
An excellent idea. If somebody installs MoinMoin on the jboss site, I would be willing to add a few initial pages modeled on standard wiki sites. Here's a concrete example of where a wiki would have saved myself and others time: I attempted to disable an Mlet in jboss.conf by bracketing it with an XML comment. That didn't work. Numerous list searches yielded many hits but none pertaining to the problem. An oblique reference in the jboss manual hinted at a distinct jmx Mlet entry format but perusing the referenced jmx spec shed no light. By trail-and-error, I discovered that the jmx jboss.conf reader doesn't recognize XML comments, despite the XML-like format. After further list search, at least two jboss users discovered the same thing, also by trial-and-error. The discovery remains uncaptured in any useful format. It is one of numerous jboss nits that don't really belong in a user guide but are lost in the user list. A wiki would categorize and capture such items directly and dynamically.

[JBoss-user] Oracle Autocommit?
Hi all, After hours of going through the JBoss-user Archives, I'm still unclear as to exactly what is going on with regard to JBoss's interaction with Oracle, Transactions, and autocommit. Here is my particular problem: 1. methodA1() in a Session Bean (SBeanA) is responsible for creating a particular type of CMP Entity Bean (EBeanZ). 2. EBeanZ and all member methods are Container Transaction Managed set to: Required. 3. SBeanA and all member methods are Container Transaction Managed set to: Required. 4. methodA1() in SBeanA calls methodA2() in the same bean (SBeanA). 5. methodA2() is responsible for creating another type of CMP Entity Bean (EBeanY). 6. EBeanY and all member methods are Container Transaction Managed set to: RequiresNew. 6.1. There is a 1 to many relationship between EBeanZ and EBeanY respectively. 7. Everything works until I get to #5. That is, the following message is generated in the log files upon attempting to persist/create EBeanY instances (note the first line of output is caused by a system.out in the ejbCreate method of EBeanY): [EBeanY] ejbCreate: Attempting to create: SCULE for owner: 100160 [SBeanA] Transaction XidImpl [FormatId=257, GlobalId=buzzwin2//7, BranchQual=] timed out. status=STATUS_ACTIVE [SBeanA] Transaction XidImpl [FormatId=257, GlobalId=buzzwin2//8, BranchQual=] timed out. status=STATUS_ACTIVE That's it. No more info, although I still have to set db logging when I find the correct property/flag. Does anyone have any ideas about what is going on, and how I have to fix it. If this has to do with autocommit, do I need to modify the jboss code to setAutoCommit(false)? Thanks in advance for any suggestions / help.

RE: [JBoss-user] any consequences to use JDBC_ODBC bridge?
Sun advises against using the JDBC-ODBC bridge for production purposes. Besides not being very efficient, it is single-threaded. But Microsoft themselves have had problems getting their ODBC driver to work in multi-threaded mode -- see the knowledge base. One supposed fix supplied by Microsoft was to make the calls into the ODBC driver synchronized.

Re: [JBoss-user] Oracle Autocommit?
Hi, I have no ideas if this is what is causing the problems you are experiencing, however... If I was designing the db for this, and if I understand you correctly, I would have tableZ for EbeanZ, with pk pkz and tableY for EbeanY, with pk pky, and foreign key pkz from tableZ. Now, in transaction 1 you insert a new record in tableZ, with a brand new pk value. Before committing, you start transaction 2 and try to add some records to tableY, with the new pkz value you just got. This value in tableZ is not visible to transaction2, transaction 1 hasn't committed yet. So you would get a fk violation. Why does (6) need to be RequiresNew? All this being said, it might be helpful to know which driver you are using and the configuration files. Autocommit is always already set to false.

[JBoss-user] Duplicate primary keys returned by findAll()! (CMP)
Hi,
I am using JBoss 2.2.1 with CMP beans using hypersonic as the backend
(default config).
For three weeks, we have been running the same application that creates
9 products (once, after wiping the database and restarting jboss). The
primary key is Product.name (String). Yesterday, ProductHome.findAll()
started returning 14 products, some having duplicate primary keys.
This raised three questions.
1. Is there any known issue that would "create" entity beans WITHOUT
their home.create() being called (the duplicate products appear some
time after they are created).
2. How can findAll() return duplicate primary keys? Shouldn't
hypersonic disallow this, or is this a jboss/jaws bug.
3. Is there any way to stop this behaviour, it seems pretty serious.
I have tested the duplicate primary keys to see if they are references
to the same objects (==), and they are not.
What the hell is going on? Any help would be greatly appreciated.
Thanks,
Lisa

[JBoss-user] Problems in working with another EJB jar file
Greetings all, I tried to play with the TravelAgent example in Monson-Haefel¡¦s EJB book on JBoss 2.2.1 and Win2K. It¡¦s a session bean calling another entity bean named Cabin, but not in the same .jar file. I read the JBoss doc about this example by Sebastien Alborini, but got the error about unable to get the home interface of Cabin. I¡¦m sure that the Cabin is working probably. Here is the ejb-ref section in ejb-jar.xml for TravelAgent: ejb/CabinHome Entity com.titan.cabin.CabinHome com.titan.cabin.Cabin Here is the jboss.xml for TravelAgent: TravelAgentBean ejb/CabinHome CabinBean Could anyone kindly advise what¡¦s wrong OR post the working code/configuration? Thanks Best Regards, Zeon
