[JBoss-user] Out of sync EJBs after passivation
Hey, all, I'm having a problem that looks to be a variation of a problem posted here earlier. However, I never saw if it was classified a bug and is being fixed, or if there is a workaround. I have an EJB A. It contains one to many EJBs B. When I retrieve several A EJBs via a column other than the primary key, they load and get the B EJBs associated with them. Everything works fine. After a few minutes, everything passivates and I try to retrieve the same set of A EJBs. But the B EJBs have now scrambled and are associated with the wrong A EJBs. (Side note: I've heard that EJBs containing other EJBs is not recommended, even by Sun, but I also need to get B EJBs directly in other parts of the application.) It appears this is probably the same issue under the subject of Serious Bug? EntityBean out of synch with database. However, I am not using EJBDoclet and I am using BMP. The interesting thing is, I put some logging in ejbActivate() and ejbPassivate(). No other code is in those methods. When they EJBs are passivated and activated, they look fine. It is when my application tries to access the data when the trouble arises. I tried re-retrieving the B EJBs in ejbActivate(), but that also didn't help. Is this a bug? Is there a workaround? Thanx.

[JBoss-user] Cached selection list - design question
This is more of a design question rather than JBoss specific, but I thought it was a situation that other people have encountered and was wondering what they did. I'm sure the answer would be helpful to others. I have a table in my db that indicates valid types for one of my business entities. They won't change very often, but often enough that I didn't want to update code everytime changes are made. I want to load these types into an object and cache them so that I don't have to go to the database to retrieve them each time. In a previous post, there were suggestions for me to use a stateless session bean for user transaction recording because entity beans are expensive and I don't need to keep the bean around after the transaction is recorded. Would a stateless session bean make sense here? I could keep an internal cache that retrieves data if it is empty. As I understand it, a stateful session bean wouldn't make sense because there is a valid state for each client. There is essentially only one state in this case. Would an entity bean make sense? If so, I would probably use a findAll() method to get all the possible types. Would JBoss (or other app server) cache all these EJBs so that next time I call a findAll(), it woudn't go back to the db for the data? Would all these EJBs hold too much memory captive? The type list isn't very big, but I will have many such lists. Thanx for your advice. Norton ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user
RE: [JBoss-user] Database inserts via stateless session beans
Yes it was. I changed it to 'Container' and it works fine. After further reading, I understand now that I had told JBoss that I was going to manage the database transaction myself. So the database insert didn't work because there was no transaction involved (no commit). Is that correct? Thanx.

This is the problem. This is delegating to the Object.hashCode method
that uses the object's address as its input, so when the verifier tries
to verify that your hashCode method is right (by creating two keys and
comparing the hashes) it gets different answers when it should get the
same answer.
maybe
return _guid.toString().hashCode()

RE: [JBoss-user] Primary Key warnings
Ah... I understand now.
The problem is that my GUID class, by definition, creates
a new GUID for every call to the default constructor. I
use it to create unique IDs for newly created EJBs.
Therefore, the below code could never be true. Given
that, I guess I'll just have to live with the warnings.
I'm assuming I'm not violating the EJB spec by designing
my PK class like this, am I? I'll have to check into that.
I was thinking that you guys (the JBoss developers) were
checking for equals() and hashCode() this way due to
the spec, but I guess there's no other way for you to
check for the override of these methods generically.
Thanx to everyone that tried to help.

Norton,
I had this same problem. The code you are running into follows:
Object one, two;
try {
one = cls.newInstance();
two = cls.newInstance();
try {
if(!one.equals(two)) {
status = false;
fireSpecViolationEvent(entity, new
Section(9.2.9.b));
}
} catch(NullPointerException e) {} // That's OK - the
implementor
expected the fields to have values
try {
if(one.hashCode() != two.hashCode()) {
status = false;
fireSpecViolationEvent(entity, new
Section(9.2.9.c));
}
} catch(NullPointerException e) {} // That's OK - the
implementor
expected the fields to have values
} catch(IllegalAccessException e) {
// other stuff..
As you see your pk class needs to either throw a NullPointerException or
return a hash codes that are equal. This is kind of lame, so I just
have my
PK just throws a NullPointerException when equals or hashCode is called
on
an uninitialized instance.
By the way, I think the _guid field must be public for CMP to work.

[JBoss-user] Immediate deletion of object from cache

I've never been able to count on answers from some mailing lists, let alone useful ones. On to my question: Is there a way to force a deletion of an entity bean in the cache after creation? I have a system where I'll be logging user transactions in one of my tables. I won't ever need to access them again. Is there something I can specify somewhere so that the entity bean won't be held in cache after I leave the method that creates it?

[JBoss-user] Datasource availability
There's something I'm not understanding about datasources.
I have a utility class that includes the following method:
public static Connection getConnection() throws SQLException {

InitialContext ic = new InitialContext();
DataSource ds = (DataSource)ic.lookup(java:/mysql);
return(ds.getConnection());
}
catch (NamingException e) {
// Log exception
throw(new SQLException(Datasource not found: +
e.getMessage()));
}
}
When called from an entity bean, this method works fine. However,
when called from outside an entity bean, I get:
NamingException: mysql not bound
The jboss server.log reports that java:/mysql is bound (I also know
it is bound because it works from the entity bean):
[mysql] Starting
[mysql] XA Connection pool mysql bound to java:/mysql
[mysql] Started
The class that is calling this method also uses the entity bean that
uses the same method and the entity bean works fine.
Is there something I need to do in my non-entity bean code that the
entity bean is doing for me?
Thanx.

[JBoss-user] Auto-deploy problem
Hi, I love the auto-deploy feature of JBoss. However, it's not working as I expect it to. I created a jar file and put it in the $JBOSS_HOME/deploy directory. One of the remote interface classes didn't throw a RemoteException, and JBoss reported that problem on the auto-deploy. So I added the 'throws RemoteException' to the interface definition, compiled, jar'ed it up, and copied it to the deploy directory. JBoss recognized the change and attempted a redeploy, but the same error came up. When I stop and start the server (without a change to the jar), the auto-deployer doesn't report any errors and my new application is successfully started. Shouldn't the auto-deployer have retrieved the new class file and deployed my app successfully without a restart? Thanx.

RE: [JBoss-user] NoClassDefFoundError: javax/servlet/http/HttpSe
I'm not using the system classpath to add jars. I uncommented the section about Tomcat in the JBOSS_HOME/conf/default/jboss.conf file: !-- Uncomment to add Tomcat classes to classpath -- MLET CODE = "org.jboss.util.ClassPathExtension" ARCHIVE="jboss.jar" CODEBASE="../../lib/ext/" ARG TYPE="java.lang.String" VALUE="/usr/local/jakarta-tomcat-3.2.1/lib/" ARG TYPE="java.lang.String" VALUE="Tomcat" /MLET Upon startup, the log shows that all the jars in this dir are being added to the classpath (see the log snippet in my original note). The j2ee.jar is not being added automatically, but I've read a previous message that JBoss doesn't play well with j2ee.jar. I have tried adding j2ee.jar to the classpath upon invocation of org.jboss.main and there are all kinds of error messages that appear upon restart. SoI don't believe that is the right approach.

But first of all, it would be best if you didn't use the system classpath while jboss start up! Just too many errors could happen with that! Make sure that your java installation is good and it should pick up the j2ee jar automatically. Do you want to verify that? Putting the servlet jar in ext was just to force it to load it! Vinay - Original Message - From:Norton Lam Sent:Wednesday, May 02, 2001 3:09 PM To:'[EMAIL PROTECTED]' Subject:RE: [JBoss-user] NoClassDefFoundError: javax/servlet/http/HttpSe Vinay, Thank you for your quick reply. I tried adding servlet.jar to JBOSS_HOME/lib/ext and restarted, but it didn't work. As I understand it, JBoss and Tomcat are running under the same VM (1.2.2-RC2 in this case) so any servlet.jar being added in the classpath extension should affect both Tomcat and JBoss. Besides, if it is only Tomcat that gets the classpath addition, it should still work because it is Tomcat that is processing the servlet, not JBoss, right? Thanx for your help.
