There is nothing in the spec that says war files can specify dependencies
using the manifest Class-Path attribute. In fact in the J2EE 1.3PFD3 spec
says:
J2EE.8.1.1.2 Dependencies
A .jar file can reference another .jar file by naming the referenced .jar file
in a Class-Path header in the referencing .jar file's Manifest file. The referenced
.jar file is named as a relative URL, relative to the URL of the referencing .jar
file. (This mechanism is only applicable to JAR format files containing class files
or resources to be loaded by a ClassLoader; such files are always named with a
.jar extension. This mechanism does not apply to other JAR format files such as
.ear files, .war files, and .rar files that are never loaded directly by a
ClassLoader.)
Are you using this archive format successfully with another app server?

Any class loaded from the standard WEB-INF/classes or WEB-INF/lib/*.jar
is certain to be loaded by the servlet war class loader. At what point are
you trying to do the reflection, and how are you loading the class? I would
expect that using the thread context class loader should work:
public void init() throws ServletException
{
ClassLoader loader = Thread.currentThread().getContextClassLoader();
Class clazz = loader.loadClass("myClass");
...
}

I guess this is not written anywhere in any spec, but why classes in the war file should be aware of classes in EJB jar file ? One needs only home and remote interfaces in war file for all EJBs deployed and that's it ... Or is there something more ? I assume that this is probably an optimization of JBoss architecture, also being spec compliant. But the question still remains : shouldn't be a clear separation between classloaders and classes from EJB jars and war files ?

Re: [JBoss-user] Apache+Tomcat+JBoss
See my immediately prior post on the subject of native thread support in Linux. The short answer is that it is present -- and the referenced jBoss documentation already wrong -- as of kernel 2.2 and Sun JVM 1.3. The Linux 2.4 kernel makes substantial internal changes to the scheduler, especially with regard to SMP, but this is transparent to applications such as jBoss. (The exception to transparency is that threading errors, such as failure to synchronize properly, may be exposed by a 2.4 kernel if the same code was working by coincidence on a 2.2 kernel.) >From the perspective of a Java application, the 2.4 kernel should be regarded as architecturally equivalent to a 2.2 kernel, although there would likely be significant performance benefits, especially with SMP. -- Mike On 2001-06-24 at 11:25 +0100, Julian Gosnell wrote: > Further context to this quote suggests that Linux 2.2 is being > discussed. > > Firstly, can anyone confirm this from a reliable source - it's the > first I've heard of it. > > Secondly, is this still the case with a 2.4 kernel, in which I thought > similar issues had been very successfully addressed ? > > Thirdly, It would be useful to have dates on documentation, so that it > is possible to tell when they become stale - if 2.4 does address this > (I have no idea), or a better Linux JVM has since been released, then > it would be helpful to know when this statement was made. > > Jules > > > > Fei Wang wrote: > > > I have found the following at > > http://www.jboss.org/documentation/HTML/ch10s02.html. > > > > Linux users probably already know that linux does not support real > > threads.

RE: [JBoss-user] Apache+Tomcat+JBoss
The jBoss documentation is simply wrong and grossly outdated in any meaningful way. See my extensive post on a related issue a few days ago: http://www.mail-archive.com/jboss-user%40lists.sourceforge.net/msg07518.html Linux, as of the 2.2 kernel and 1.3 Sun JVM, certainly does have real native thread support, and this is the default installation. See: http://developer.java.sun.com/developer/technicalArticles/Programming/linux/ Basically, the choice between "native" threads and "green" threads is an issue of whether the threads are to be scheduled by the system kernel scheduler or by the JVM internal scheduler. If the system scheduler is used, the switching takes place in kernel mode and more efficient use of resources can be made; in particular, an SMP machine can have multiple JVM threads running simultaneously on different processors. If the JVM internal scheduler is used, the switching takes place in user mode which is going to be somewhat slower, and all of the threads within the JVM will be limited to a single processor on an SMP machine. There is a trade-off here: for nearly all practical Java applications, running with native threads is going to result in better performance, even for a uniprocessor machine. The exception is a Java application which needs to create a huge number of threads, maybe into the several hundreds, in which case green threads might be a realistic option. Note that any application which has hundreds of threads is going to thrash the scheduler regardless of whether that scheduler is inside the JVM or the kernel, and serious consideration should be given to rearchitecture. There is some sort of nasty myth that Linux threads are somehow less "thready" than Windows threads because they show up in the process table. This is an implementation choice that has negligible effect on performance (after a thread has been initially created) because threads share task descriptors which, on most hardware (including Intel), have physical meaning in the CPU. In other words, the Linux kernel switches between threads as quickly and with essentially the same amount of overhead as a thread switch on Windows, although Linux does take some penalty in initial thread creation. This is again a trade-off, because the Linux thread model allows a single-tier scheduling algorithm while Windows requires a double-tier scheduling algorithm. What green threads on Linux do is closer to the Windows scheduling model, although on Windows the thread scheduler runs in kernel mode and is therefore faster than the user-mode JVM internal scheduler on Linux that is only used with green threads. The reason Linux will impose limitations on jBoss capacity that are not present in Windows is because the Linux kernel is designed with the assumption that any process spawning hundreds of threads has lost its mind and should be stopped for the good of the system. If one chooses to do so, one can -- as I explain in my earlier post referenced above -- recompile the Linux kernel to raise the task count limit up into the stratosphere; a little more than 4000 tasks can be allowed systemwide on Intel hardware. (This has a physical hardware basis: there are 8192 descriptor slots on Intel hardware, and each Linux task needs two, so the dead maximum capacity on Intel hardware is 4096. In turn, no single user is allowed more than half the systemwide supply of task slots, so when jBoss hits 2048 the kernel will deny it the ability to start new threads. Note that this is a factor of 8 greater than the kernel default.) With the kernel recompiled to allow more tasks, Linux will have essentially the same capacity in terms of thread count as Windows, with the difference that Linux will continue running if a non-root application requests every available thread while Windows in that situation will crash. In summary: 1. Linux has native thread support as of the 2.2 kernel and 1.3 Sun JVM, 2. SMP, if available, is fully utilized with native thread support, 3. There are reasons why one might choose not to use native thread support on Linux and use green threads instead, 4. The capacity of Linux in terms of thread count can be boosted to a level equivalent to that of Windows by changing a number in the kernel source and recompiling, and 5. It is undesirable to have very large numbers of threads because then the system will spend an increasingly larger portion of time in thread switching and scheduling overhead at the expense of useful work. -- Mike On 2001-06-24 at 14:08 +0800, Fei Wang wrote: > I have found the following at > http://www.jboss.org/documentation/HTML/ch10s02.html. > > Linux users probably already know that linux does not support real > threads.

Re: [JBoss-user] database access using Datasource in stateless session bean
It's basically the same as getting the datasource from within a BMP entity bean: declare a resource-ref in ejb-jar.xml (unless you're using JBoss defaultDS) Map a resourcemanager to your datasource and the resource-ref to that resourcemanager in jboss.xml (see jboss.dtd) Write your bean to look up the datasource at the name "java:comp/env/"+the res-ref-name you specified in ejb-jar.xml (you should name it starting with jdbc, like "jdbc/MyDataSource") get a connection perform JDBC stuff in a finally block, close all resultsets, statements, and connections (in that order, to be paranoid) Sorry I don't have an example right now, but if you look at the typical BMP example, you should be able to get it. -danch felix wrote: > where can I find an example of stateless accessing to a database by a > datasource?

Re: [JBoss-user] Limiting the number of instances of Stateful Session Beans
Let me suppose that you are going wrong way. First, what you need seems more the 'singleton counter' problem than bean container problem. You may check corresponding threads to solve problem in such a direction. IMHO the best solution is to use JNDI+RMI (look at Roman's 'Mastering EJBs, p406) Second, trying to change container parameters to solve application problem may intersect with another application in the same container. Limiting the number of bean instances may have influence on caontainer perfomance. Third, keep in mind that solution sholud be portable and scalable.

[JBoss-user] Problem with classloader, servlets, and EARs.
I'm hoping someone can shed some light on a problem I'm having. I have a EAR structured like somewhat this: (names changed to protect the innocent) myApp.ear |--- myLib.jar | |-- myServlet.class | |--- myWeb.war |-- WEB-INF/web.xml |-- WEB-INF/classes/myClass.class When myServlet.class loads, it tries to instantiate (by reflection) an instance of myClass. However, it gets a ClassNotFound exception. My tentative guess at what's going on is that myServlet is being found by the classloader for the EAR. This doesn't have access to the contents of the WAR file, so it doesn't see the web classes. This implies that I need to get hold of the classloader for the web-application. Does anyone have any idea on how to do this? I'm stuck. (Yes, the code works fine if I move myClass.class out to myLib.jar, or if I move myServlet.class into the WAR.

Great that it worked. Any feedback on the jms-ra stuff is wellcomed, since
it is a non standard way of using the two standards (connector and JMS).
Since you are not allowed to use asynchronous stuff with the connector I
did not think that start was applyable, but we may have to rethink that.

[JBoss-user] user identity to the database question
Currently, I am building a prototype that has a requirement that the database knows who is access a row in the table. This arrangement is so that we can audit who creates and who last updates a record. I am using version 2.2 of JBOSS running on Windows NT. The database is a Sybase database and their JDBC drivers. When a row is either inserted or updated, the identity seen by the database is that given to initially create the pool. Is there a way to get the identity of the user invoking the entity bean to be passed onto the database? Any help would be greatly appreciated, thank you. ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user
[JBoss-user] who can state it clear about primitives?
I think, it is time to ask a final answer about usage of primitives. In RMI it was not clear too. I read, I can not use them in remote interfaces with rmiregistry, but in practice it worked, and other people confirmed it. If it depends on implementation, let us just talk about JBoss. 1. Can I use primitive arguments and return types in remote interface methods? 2. As persistent fields? 3. As a primary key and its subfields? And what would be an XML tag if yes? Does the tag exist?

Either put the required classes somewhere the server can find them, e.g. by adding them to the JBOSS_CLASSPATH, putting them in $JBOSS_HOME/lib/ext or (possibly, I'm not really sure) adding a classpath extension thingy in jboss.jcml. These options are good if the classes are required elsewhere in the server, e.g. by EJBs that use the resource adapter. If the classes are only required by the resource adapter implementation then you can put the classes in the RAR.

[JBoss-user] Declarative Transactions don't work, please help URGENT !
Dear jboss-users
I need to use declarative transactions in my project.
Unfortunately I cannot manage to have my transactions
rolled back when there's an error. So this is
my scenario:
I have a Session bean Stateless with attribute:
Stateless
Container
And 2 Entity beans with attributes:
Container
Required
Container
Required
Now inside the session bean there's a method
that calls the Entity bean create method
void doMusic() {
CD c = (CD)homeCd.create(50);
c.setTitle("Title1");
c.setArtist("Artist1");
Tape t = (Tape)homeTape.create(100);
c.setTitle("Title2");
c.setArtist("Artist2");
}
Now this is the matter- if the second bean (in this case Tape)
fails (because of duplicate Primary Key) then the first create
is NOT rolled back!!! When I issue a ?select? of the CD table
the row is added.
Why it happens so ? I want that both "create" share the same
transaction so I set up tx-Required in both of them.
A last note: I'm using PostgreSql as DB.
I'd be very very grateful if someone gives me an advice.
Thank you very much

[JBoss-user] Session bean instead of entity bean
Hi all EJB guru's I am currently working on the enterprise application, where the performance is one of the most important factors. I have made some simple performance tests with JBoss-Tomcat installation and I have found this: Using stateless session beans for database querying gave the best performance results. The worst results I reached with CMP Entity bean. We have quite complex database entity model (about 200 tables) and we almost always need more complex joins to obtain the required results. Also it is a nightmare for me to imagine to make any structural changes in the entity bean (e.g. attribute name or type change). According to this we would like to model the most of our bussines methods using session beans (mostly stateless) in connection to DAO objects for db manipulation. We would like to use entity beans just in the case where it is worth to cache data outside the database. May be I do not see any other advantage of using entity bean (except caching the often used data) in comparison to session bean. Isn't the session bean very good alternative for entity bean in the complicated database entity model? Thnaks for any comments. Mark --- Outgoing mail is certified Virus Free.

Re: [JBoss-user] question
Per the spec The ejb-name element specifies an enterprise bean’s name. This name is assigned by the ejb-jar file producer to name the enterprise bean in the ejb-jar file’s deployment descriptor. The name must be unique among the names of the enterprise beans in the same ejb-jar file. The enterprise bean code does not depend on the name; therefore the name can be changed during the application-assembly process without breaking the enterprise bean’s function. There is no architected relationship between the ejb-name in the deployment descriptor and the JNDI name that the Deployer will assign to the enterprise bean’s home - Original Message - From: Marek Sedliak Sent: Sunday, June 24, 2001 11:39 AM To: [EMAIL PROTECTED] Subject: RE : [JBoss-user] question Hi Deanyou can use jboss.xml where u can specify JNDI namespace.

Re: [JBoss-user] Apache+Tomcat+JBoss
Further context to this quote suggests that Linux 2.2 is being discussed. Firstly, can anyone confirm this from a reliable source - it's the first I've heard of it. Secondly, is this still the case with a 2.4 kernel, in which I thought similar issues had been very successfully addressed ? Thirdly, It would be useful to have dates on documentation, so that it is possible to tell when they become stale - if 2.4 does address this (I have no idea), or a better Linux JVM has since been released, then it would be helpful to know when this statement was made.

Re: [JBoss-user] Transactions problems
To add, If you need all the methods to commit one shot via the Session bean facade you'd probably specify the transaction for the session bean method as 'RequiresNew' so that the container starts a new transaction for you and the transaction setting for all entity bean as Required so that they blend into the transaction that the session bean created. And hence when all the methods in the entity bean complete and the session bean method returns your transaction would be committed.

My *.ear file which I place in the ~/jboss/deploy dir looks like this. cais-1.0.ear |- META-INF |- cais-1.0-client.jar |- cais-1.0-ejb.jar |- cais-1.0-web.war |- jdbc7.0-1.2.jar From the logs -- [J2EE Deployer Default] couldnt add ./jdbc7.0-1.2.jar to common classpath: /u/public/JBoss-2.2.2_Tomcat-3.2.2/jboss/deploy/jdbc7.0-1.2.jar (No such file or directory) *** With the above problem I did put a carriage return after the Class-Path in the MANIFEST.MF as the docs say, but didn't help.
