[JBoss-dev] [ jboss-Bugs-431336 ] Problem with SecurityManager and Proxies

I find I only get proxies working if I have a security domain, for which I need to be logged in (OK) - my client logs in and tries to create the home interface. I get a null pointer exception in the server. The problem appears to be that in StatelessSessionInterceptor.invokeHome, it does not set the EnterpriseContext like it does in invoke(), and thus on line 148 of SecurityInterceptor, where it attempt to do: EJBContext ctx = mi.getEnterpriseContext().getEJBContext(); in invokeHome, it dies. I guess that there is not EnterpriseContext during invocations on the home inbterface, so maybe it should not be trying to retrieve it, or the Interceptor invokeHome functions should look pretty much the same as the invoke functions, setting the EnterpriseContext. Great Looking Product. I'll have to use it more!

[JBoss-dev] CMP fields XML Serialization
Hi, In CMP Entity beans, fields that can not be mapped automaticaly to primitive SQL type are serialized and saved as Object in the database. One problem is then if you want to change the Object, you have to take care of Serialization versions,... everything is not possible here. Another problem is if you want to give access to your db to a non Java world. One solution for that could be to XMLize the object to a VARCHAR/String format. The power on changes of the Object will be more powerfull by implementation of method like "importXML" and "exportXML". What do you think of a feature like that ? What I try to avoidby using that is BMP , TopLink/Castor, XML/Object Databases.

RE: [JBoss-dev] MarshalledObject + URLClassLoader = huge network traffic
Hello Oleg, I agree with your idea that this setting should be optional. Nevertheless, I do not think it is possible to do true transparent dynamic classloading and not setting this URL in the stream but rather let the RMI marshaller subsystem contact a JNDI name. Nevertheless, it would be still possible to completly suppress the optional URL during the marshalling (i.e. getURLs return an empty vector) and, in the client code, to set the appropriate rmi system codebase properties such that the dynamic classloading can occurs. The problem with this approach is that the client is only able to dynically download code from a single source whereas with the "standard" way, you can have as many sources as you want.

[JBoss-dev] FYI: Interesting newsletter *was* WG: 2001-06-07 TJSN [022] - Classloaders Revisited: "Hotdeploy"
A friend of mine (he´s a real Java crack located in ZA!) edits a newsletter
series
that might be of interest for you and other people from the JBoss
development
community.
I was so free to compile some of our classloading thoughts to a (hopefully)
didactic
example ...
If you are interested, subscribe and ask him to send the back-issue archive
...
he had already and still has a lot of ill ideas (switching over objects,
virtual methods)
that he distributes in that open manner.

Welcome to the 22nd issue of "The Java(tm) Specialists'
Newsletter", sponsored by infor business solutions AG, an ERP
company based in Germany (http://www.infor.de). Many thanks go
to Christoph Jung for again making an excellent contribution to
"The Java(tm) Specialists' Newsletter" by taking the time to
write about some of the advanced things he's busy with. This is
the longest newsletter so far, and also the most in-depth. Don't
start expecting the same quality when I write ;-), in fact, I
might skip next week's letter to give you some time to digest
this one.
As always, I would like to ask you to forward this newsletter to
anybody you know who might be interested in Java. Please also
remember that if you are a beginner in Java, some of these news-
letters will go over your head. Don't give up!

Classloading revisited

A few weeks ago, I was in the middle of an ICQ chat with
our admired Dr. Kabutz when he suddenly uttered a definite
"hi, hi" which took me by surprise as it was different to
the ubiquitous "emoticons" or smileys that I am used to.
Nevertheless, I was immediately able to catch the thousands
of denotations that this very special textual laughter was
transporting. In this case, the semantics can be very well
subsumed by the German term "verschmitzt" which is difficult
to translate to English but would probably be a combination of
"roguish", "twisty", "experienced" and "savvy". Similarly,
"ha, ha" (a very open reaction to a joke) and "ho, ho"
(kind of patronizing Santa Claus stance) are able to express
much more context than any smiley construction I know of,
at a minimum overhead of bandwidth. Measurements using WinZip
have shown verbose laughter statistically being only 5% more
expensive than its certainly poorer smiley counterpart.
And now ... I hope you kept a copy of newsletter 18 where Heinz
illuminated us with the insight that class identity in the
virtual machine is quite independent of even fully-qualified
class names. The magical constructs that he used for his
investigations were the java.lang.ClassLoader and suitable
derivatives, such as the java.net.URLCLassloader. These are,
amongst other innovations of the Java(tm) 2 Runtime, indeed
a fascinating subject for experimentation.
Classes and ClassLoaders
Perhaps you found that having several classes called "A" in your
java.exe was not very useful. On the contrary, it probably
required quite an effort to keep the various sources and class
files of that newsletter in separate directories. However, I
would like to demonstrate how this rather theoretical possibility
has significant practical value when it comes to building real
programs that are able to simultaneously host multiple Java
applications. The most well known examples of such programs are
found in the J2EE(tm) application servers.
For this purpose, let us briefly revisit what the head of Maximum
Solutions Ltd., by the way, one of the best Java consultancies I
know of ;-) [hk: hoho], has demonstrated to our surprised eyes
and what may be already apparent from the terminology: A
java.lang.ClassLoader is an object that is used to locate
external resources (such as *.class file placed in a directory or
zipped into a jar-file) and to import the contained byte code for
constructing java.lang.Class instances at runtime.
Each java.lang.Class in the JVM is hence associated with its
so-called "defining classloader" that has imported it and that
can be obtained using the Class.getClassLoader() method. For
example, regard the following classes stock.Warehouse (interface
to a mono-product warehouse exposing a reservation method) and
sales.Order (remotely connects/links to a warehouse to satisfy
the order in quantities of size "bunch").
// stock/Warehouse.java
package stock;
/** Sample remote interface that is linked by sales.Order. */
public interface Warehouse extends java.rmi.Remote {

[JBoss-dev] [ jboss-Bugs-431478 ] EJX breaks with cloudscape in lib\ext
Bugs item #431478, was updated on 2001-06-08 13:51 You can respond by visiting: http://sourceforge.net/tracker/?func=detail&atid=376685&aid=431478&group_id=22866 Category: None Group: v2.2.1 (stable) Status: Open Resolution: None Priority: 5 Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: EJX breaks with cloudscape in lib\ext Initial Comment: I am setting us JBOSS to use the Cloudscape database distributed with J2EE1.2.1. I copied the 2.2mb cloudscape.jar from %J2EE_HOME%\lib to %JBOSS_HOME% \lib\ext so it would be automatically added to the classpath. After this, I could not create a new xml configuration in ejx using the File:New menu.

[JBoss-dev] Option D in SynchronizationInterceptor
Hi, Why is the validContexts in the new option D enabled EntitySynchronizationInterceptor *NOT* synchrnoized. Will you really have a thread safe implementation in that case? I'd sent out an implementation of the soft ball cache refresh option sometime back [which I never got time to check in!!] and that was after finally persuading Marc that we had to synchronise the hashset. Also, a. the hashset is unique anyway why check for presence! b. there will be only one ctx per bean [correct me if i am wrong]. Also then we'd planned to have it as a separate class that could be fit into the inteceptor stack if required. Vinay Vinay

I agree mostly, but then 11.6.3 is really annoyingly unspecific,
allows the container to do almost anything (there is a "the
list is not inclusive of all possible strategies" sentence)
and leaves the bean developer in the wet ("the enterprise bean
must be written conservatively not to rely on any particular
Container behavior.")

I had a look at TxInterceptorCMT.java and you seem to be right,
the business/home method is invoked without any transaction
context (when requested by Supports, Never and NotSupported) and
there seems to be no attempt to set autocommit to true ... and as
there is no active transaction at all JBoss CAN'T do a rollback
after method invocation.
So the rollback you see in your debug log must come from somewhere
else, might be from your JDBC driver?

As I just told, I don't think JBoss is rolling back, it would be
too stupid to do that and leave the out of sync instance in memory,
hey, there may be some subtile errors in JBoss still, but no
sillyness.
But I agree, it might be best to set autocommit to true, would
avoid problems with drivers not knowing how to handle statements
without a TX and should be fairly easy to be implemented (at
least for the gurus here on the list).
As I said before you should NEVER attempt to write a bean
outside a TX, as there is no guarantee at all, that any EJB
server (including JBoss) will actually call ejbStore() (see
spec 9.1.7.1).
9.1.7.1 suggests DB access in the business methods instead, this
should work, if autocommit were on and the bean were not reentrant.
But I would suggest another schema:
- use commit option B
- have your getters and finders Supports
- have your create/remove and setters Required
- mark the bean as reentrant
- access your Entity beans through a Session bean facade
to have declarative Transaction attributes (and business logic);
alternatively use UserTransaction in your clients (does NOT
work with JBoss 2.2.2 yet, but only with the CVS version)
- read without TX for pure display purposes, where reliability
isn't that important, you gain advantage from JBoss caching
the beans state with option B and without TX
- write within a TX, option B forces ejbLoad() before the
business method executes and you have reliable data to
modify; if your modification depends on the actual state
you are free to first read the state then calc and write
the state all within one and the same TX from the session
bean
my very best regards
Georg

As far as I remember Marc was never really conscious of synchronization in this case, worst case that can happen in a race between looking for a ctx and adding to/clearing the hashset would be the lookup failing, thus synchronizing an instance earlier than neccessary. On the other hand the docs explicitely require synchronization on HashSet, I don't know what happens in a race between adding and clearing the set, maybe some internal structure will break. Though I could look at the implementation, I believe it's better to do NOT, but stick with the docs, as the implementation might change without notice!

Don't exactly know what you mean, but the HashSet is only used for commit option D and the class handles A,B,C also. > b. there will be only one ctx per bean [correct me if i am wrong]. Do you mean one ctx per bean CLASS? No, the ctx has i.e. the transaction and the security settings attached, so there is one context per bean INSTANCE, isn't it? > Also then we'd planned to have it as a separate class that could > be fit into the inteceptor stack if required.

Re: [JBoss-dev] Fast Updates Based on Row ID
Hi Dan and Vinay, > The reason I was suggesting an oracle specific option name was because I > really think that we need to use the Oracle specific syntax to return > the rowid value on inserts. Oops, I forgot about that. But Vinay is right, a stable ROWID might be present in several other databases already or in future. The 'insert ... select into' syntax today seems to be Oracle 8 specific (remember, Oracle 7 does not have it), but could make it into some standard? At least one and the other are not too closely related, this syntax especially can get back whatever you want from the just inserted row, not only the ROWID, but even some sequence value, some expression list to be more general. And other DB's having a stable ROWID ain't lost, as Vinay's code now falls back to the PK when a ROWID value isn't available. So I suggest 'stable-rowid-column' (including good docs) and a new tag 'insert-select-list' specifying a comma separated list of expressions to select from the inserted row and an appropriate number of placeholders for the result after a semicolon. (Or better, feel free to define the syntax, you got the idea). bye, my very best regards Georg ___ ___ | + | |__Georg Rehfeld Woltmanstr. 12 20097 Hamburg |_|_\ |___ [EMAIL PROTECTED] +49 (40) 23 53 27 10 ___ Jboss-development mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-development

However, in j2ee_connector-1_0-pfd2-spec.pfd, section 5.8.2 Scenario: Connection Matching, it appears to me to indicate that the the application server/pool should select a set of candidate managed connections from the pool, and use the matchManagedConnections method on the ManagedConnectionFactory to actually pick the one to use.
