Re: [JBoss-user] NamingService initialization problems--ConnectionException
The problem is the warning msg displayed at the start of the server startup regarding the jndi.properties file. You have a jndi.properties file in your classpath that most likely contains a provider url which puts the naming service in client mode and so fails to connect to the non-existant server. Remove the jndi.properties file from you classpath and all will be fine.

RE: [JBoss-user] select count(*) from ... during CMP bean creation
It occurs to me that if you expect the insert to normally succeed, you could start by trying the insert, if it fails you can investigate further with the count(*) query to see if the problem is the existing row. This would be one access for success, 2 for failure instead of 1+ for failure and 2 for success (Even if the key is missing, the insert might fail for other reasons.. maybe a unique index). I support this idea. Some time before I've used the same technique for the small datawarehouse, it worked perfectly. Another possibility (presumably for the future) would be to have JAWS customizable with a plugin/database vendor and recognize their error messages. That would be great. I've tried to customize the JAWS jdbc command object, but left that idea because of complexities: The reason is the inheritence of all JDBCcommand. Usually one need to change only JDBCCommand in order to customize it to the database, but then you're not able to tell all other commands to use new one. I suggest that we define the abstract class that can takes JDBCCommand as constructor parameter and then invokes all methods on the passed JDBCCommand. All concrete commands should be inherited from that abstract class. It seems to me that in this case we will be able to customize JAWS for different databases easily.

RE: [JBoss-user] Does it really needed the interfaces of the EJBHome and EJBObject subclasses to exist on the client side?
Do you need the class when you compile? If the answer is positive, it would be quite sure that you would need it when you use it (during runtime) I think that is not true. You can have some interface that you need at compile time, but you definitely will have no implementation if it was created after you compiled your code. For example, your bean returns you instance of MyInterface, but the class (public class MyClass implements MyInterface) was created independently the client compilation. Then you need the dynamic class loading. In JDK 1.3 API for the java.rmi.MarshalledObject you can find that instance wrapped by the MarshalledObject is annotated with the URL for codebase. However, I never tried it. Maybe somebody else used this technique? Regards, Roman ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user
[JBoss-user] RE: Open letter: ZOAP is dead, long live JBossSOAP!
Hello ! 6 months ago when our project begin, we needed to integrate a SOAP layer to access an EJB container. We naturally look at JBOSS/ZOAP and find it very interesting. We succeed to ran the first sample with the help of Christoph Jung. Unfortunally the lack of documentation and the presence of proprietary files (infor.de ) in the zoap distribution makes me look at the full open source Apache Soap package. Now we have configured the SOAP 2.1 distribution to access the JBOSS bean we have developed. For our needs, we have even developed a MessageDrivenEJB provider for the SOAP package. I post a lightweight version of it on the SOAP dev mailing list (just an other way to promote the JBOSS project ! ). But to be honnest we are waiting for the next release of Apache SOAP called axis which should be faster in using a SAX soap parser. Anyway, we'll be happy to share our experience with Apache SOAP with the JBOSS users. Ideally, i hope that one day JBOSS/SOAP integration would be as great a the ZOAP idea. This means the existence of an on the fly generation of the SOAP stub/skeleton of an hot plug EJB with the integration of a well supported and active Apache SOAP distribution : the best of the two worlds.

[JBoss-user] Benchmarking Messaging in JBoss
hi list ! we are going to benchmark jboss for messaging. scenario is the following : PostingClient thread posts messages to Topic 1, with a key as identifier and some junk data variable in size (Testing Parameter 1). Messagedriven Bean 1 listens on topic 1, writes the current time to lastTimeReceivedMDB1 in the message, increases the howManyTimesSent counter and posts it to topic 2. Messagedriven Bean 2 listens on topic 2, writes the current time to lastTimeReceivedMDB2 in the message and posts it to topic 1. MonitoringClient thread listens on topic 1. MDB1, also listening on topic 1, will recapture the message and then increase counter, write time, and post it to topic 2, etc. etc. PostingClient will continuously bring new messages to the system. MonitoringClient has facilities for identifying the messages in topic 1 and will care about : - time difference between MDB1 and MDB2 and other parameters.

Hey Martin Hi, I recently upgraded from JBoss 2.0 Final to Jboss 2.2.1. Everything works as expected but now I get a IllegalStateException when creating entity beans.

As I have understood there is a bug in JBoss` caching Not that I know ;) Are you sure you return the correct pk from ejbCreate ?

Re: [JBoss-user] Backup problem?
Jim Archer wrote: Hi All... We are getting ready to put a system into production and a question occured to us. Our plan is to use jBoss/Tomcat 2.2.1 with PostgreSQL on Debian/Linux. Postgres has a pgdump utility that will allow an online backup that is guaranteed correct (from a referential integrity standpoint). Of course, we had planned to use commit option 'A' for performance reasons. So, the problem is, how do we do an online backup of a database when jBoss is running commit option 'A'? Will a backup be logically consistent with jBoss caching EBs and queries and such if we use pgdump while jBoss is running? We would prefer not to have to take the server down to do a backup. Under commit option A, entities are still synchronized _to_ the database on commit, so you won't miss any data. They're not necessarily read _from_ the database when they join a transaction, but that shouldn't be a problem with backups. -danch ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user

[JBoss-user] JBossRealm Security Bug
Hello there
There is an omission in the version of org.jboss.tomcat.security.JbossRealm

When a user requires to see one account balance, the agent shall denie the request if the user doesn't have the authority(only the owner of the account and the spouse of the owner should have access to account balance).

SV: [JBoss-user] INSERTING AN ALREADY EXISTING BEAN..... problem
This is strange Following is (was) the problem: a) Creates an entity bean with PK x b) Does a remove on this entity bean c) Tries again to create this entity bean with the same PK x. I used to (and others also) to get an exception doing this telling me that i'm trying to insert an already existing bean. What i and others thought was that the removed entity bean was still available in the cache and therefore not possible to recreate. Please note that the entity was always successfully removed from the db. I now made a simple test to show you this and what happens??? One of following is correct: 1) Same problem 2) Other problem 3) It works like a dream - no errors And the right answer is: 3) It works like a dream... Made my test in 2 variants: First when a, b and c was called in seperate transactions and then when a, b and c was called in one transaction. Both variants was working.

RE: [JBoss-user] select count(*) from ... during CMP bean creatio n
Hi, I'm not sure I understand exactly which classes you propose modifying. It looks to me as if having JAWSPersistenceManager get the class of a JDBCCommandFactory from the container metadata, and having JDBCCommandFactory descendants (and the commands they create) implement the db specific behaviour is a possibility. Is this what you were proposing? thanks david jencks On 2001.05.15 04:15:40 -0400 [EMAIL PROTECTED] wrote: It occurs to me that if you expect the insert to normally succeed, you could start by trying the insert, if it fails you can investigate further with the count(*) query to see if the problem is the existing row. This would be one access for success, 2 for failure instead of 1+ for failure and 2 for success (Even if the key is missing, the insert might fail for other reasons.. maybe a unique index). I support this idea. Some time before I've used the same technique for the small datawarehouse, it worked perfectly. Another possibility (presumably for the future) would be to have JAWS customizable with a plugin/database vendor and recognize their error messages. That would be great. I've tried to customize the JAWS jdbc command object, but left that idea because of complexities: The reason is the inheritence of all JDBCcommand. Usually one need to change only JDBCCommand in order to customize it to the database, but then you're not able to tell all other commands to use new one. I suggest that we define the abstract class that can takes JDBCCommand as constructor parameter and then invokes all methods on the passed JDBCCommand. All concrete commands should be inherited from that abstract class. It seems to me that in this case we will be able to customize JAWS for different databases easily.

[JBoss-user] Resource Management
Hi, well pardon me if I completely lack of knowledge about jboss here, but : is it possible to write an EJB application in JBoss where it is possible to dynamically manage an EJB's resources. Say Paul is an EJB component. - percentage of container cpu time consumed by Paul : the container consumes its own cpu time. Now I want that Paul, who is an EJB, consumes a max of 20% of the container's cpu time. - percentage of memory consumed.

RE: [JBoss-user] select count(*) from ... during CMP bean creatio n
It looks to me as if having JAWSPersistenceManager get the class of a
JDBCCommandFactory from the container metadata, and having
JDBCCommandFactory descendants (and the commands they create)
implement the
db specific behaviour is a possibility. Is this what you
were proposing?
Not exactly. Yes, you're right that if you go for the JDBCCommandFactory
then you're able to provide commands that can implement the database
specific functionality. However, what I propose, is to reuse the existing
commands, because almost the all functionality remains the same.
For example, if I want to override the setParameter(PreparedStatement, int,
int, Object), getResultObject(ResultSet, int, Class) or jdbcExecute(Object)
in the JDBCCommand class (to customize the serialization for example), I can
do this by
public class MyJDBCCommand extends JDBCCommand {
protected void setParameter(...) {...}
protected Object getResultObject(...) {...}
protected jdbcExecute(Object arg) {...}
}
All existing JDBC commands could be reused (the code there is basically
business logic, and not DB specific). But I cannot do this because all of
them are inherited from the JDBCCommand, not MyJDBCCommand.
That is my vision of the problem.
My idea is that all JDBC commands use delegation instead of the inheritence.
Then if I'm able to pass my JDBCCommand class as the parameter, I can reuse
current code and don't worry about the creating a bunch of classes by
copying them from existing code.
Regards,
Roman.

Re: [JBoss-user] Resource Management
How resources are managed is dependent on the container implementation. I suppose some container could allow management at that level of granularity, but I don't know of any. On the memory side, you could get close by twiddleing cache/pool configurations. Those kind of statistics are hard to come by in Java applications in general. -danch [EMAIL PROTECTED] wrote: Hi, well pardon me if I completely lack of knowledge about jboss here, but : is it possible to write an EJB application in JBoss where it is possible to dynamically manage an EJB's resources.

No, if no jboss.xml found, it uses the standardjboss.xml in the configuration dir. Same applies to the jaws.xml (it uses standardjaws.xml instead). Only ejb-jar.xml is required. This sort of thing, although not this particular one, bit me before between jboss.xml and jboss-auto.xml. It might be a good idea to put the start-up sequence and the complete list of files and their alternatives into a single place in the documentation under a heading like Starting Sequence. Many of these issues are documented, but are scattered all over the documentation. I think it might be prudent for jBoss at least to make a log entry, something like jboss.xml not found; using standardjboss.xml default instead. This would make it a lot easier to figure out what is going on. While on the subject of documentation, it would be really handy to have a keyword index of the on-line HTML manual. A utility such as ht://Dig -- http://www.htdig.org/ -- could be used to generate this off-the-shelf. For example, if someone wants to know how to configure jBoss for Postgres, they need to look under Minerva.

Re: [JBoss-user] jboss startup problems postgresql driver
I have a few suggestions. First, if you are not using Hypersonic at all, which appears to be the case, then you should remove the reference to org.hsql.jdbcDriver as a JdbcProvider. We had long hangs at the same point you did, depending upon how much memory and CPU power we were throwing at the installation. On a throw-away 166 MHz machine with 64 MB RAM running Debian Linux, we saw a hang of 45 minutes before jBoss woke up and continued initializing! Admittedly, we were specifically trying to test how far down the hardware curve we could push this. Second, I have heard that there is some sort of bug in connecting with Postgres where a password must be specified. I have not personally tried using Postgres with a blank password, so I do not know if this is true. -- Mike On 2001-05-15 at 13:46 +0200, Haug Bürger wrote: Hi, my jboss doesn't start propperly, it hangs at [myWMS] Starting [myWMS] XA Connection pool myWMS bound to java:/myWMS I removed the jboss-auto config file and moved the drivers jar-file to lib/ext.

Re: [JBoss-user] Problem making CORBA call
You shouldn't jump to conclusions like that - you might hurt yourself. Just a wild guess... I never assumed it would be correct. AFAIK, there shouldn't be any reason why you can't be a CORBA client. Well, at least that clears that up. I had looked through the spec for something saying You can't do this, but had no such luck. So I guess that narrows it down to user error. I placed the IOR string in the Java file, as I can't use I/O classes to read it from a file (as I'm doing in my Swing client). I've put some logging in the bean, and have found that the string_to_object method always returns a null object. Well, this means that the ORB wasn't able to convert the string to an object. If this were some security related problem I would expect an exception of some description. As would I. Are you sure that the IOR string is the same as you are using the Swing client? Are you running these things on the same machine? Perhaps there is an environment configuration problem. Are you using the same ORB? Are you initialising the ORB the same way? I'm 99% sure that everything is EXACTLY the same. I actually have the connection logic in a helper class - CorbaManager. The IOR string is hard coded in the class. I'm running both EJB and Swing client on the same machine. So, each create an instance of the CorbaManager object - one works, the other doesn't. I'll go and check for that extra 1% of confidence. Perhaps I'm doing something different... but I really don't think that to be the case. At any rate, knowing that it's not forbidden helps in now that I know there must be a problem somewhere Thanks, -Dave ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user

The following is how I invoke the client and the results I got: java -cp all the jar files in the client directory InterestClient Got context javax.naming.CommunicationException [Root exception is java.rmi.ConnectException: Connection refused to host: 127.0.0.1; nested exception is: java.net.ConnectException: Connection refused: no further information] My CLASSPATH is empty. The same configuration (with the java.naming.provider.url set to localhost) works perfectly when both client and JBoss server are running on the same machine. I experienced the same problem with JONAS. Could this be caused by an incorrect JDK configuration? Basically, the examples (both JBoss and JONAS) work fine as long as both the client and the EJB server are on the same machine. I would greatly appreciate if anyone can shed some light on this.

[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 {
try {
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] Error 'closing' a pooled connection
i get the following error when i attempt to return a pooled connection back
to the pool by 'closing' it:
java.rmi.ServerException: Transaction
rolledback:com/bebee/recommender/utility/DatabaseUtility
I am using org.opentools.minerva.jdbc.xa.XAPoolDataSource.getConnection() to
retrieve the jdbc connections - since I cannot find
any specific usage docs I am assuming that it works just like any other
pooled connection/resource. The code i use to close
the connection is simple enough (in a method call):
try {
if(connection == null)
return;
try {
connection.close();
}
catch(Exception exception) {
try {
if( !connection.isClosed() ); // no need to throw
} catch(Exception exception1) { }
}
}
catch(Exception exception) { /* catches everything */ }
I used the pooled connections for a day of developing without problems, the
exceptions are now raised and the only modifications
that I can think that I made were to the JDBC MBean parameters for the
pool - such as min and max pool size and timeout
values - which should not have this affect.
Has anyone run across a similar problem? The only fix I have found so far is
to NOT close the connections (Which is why I
started trimming the timeout values ;)
thanks

So, if i create new beans i have to modify my Listener to be able to comunicate with the new subscriber... The ListenerBean is the subscriber. The logic is partitioned so that the work is done in the stateless session bean. Not that it is necesarry in this example, but only to show how it is possible to do it. When it commes to an MDB, you deploy one version (name, configuration) for each logic and topic/selector combination. Some areas to use this? - A time task run in JMX could send its task to a queue. An MDB listens for missions and delegate to a sessiion bean (or does the work for itself). - A bean get some cind of thing to do. To continue it need to wait one some cind of event (perhaps the presence of something). It triggers this and returns. A message bean listens on a queue where the event will be placed and calls the session bean (that perhaps has saves som temporary persistens data throug an entity bean from the earlier invokation, which it now uses. //Peter Please, am i in the correct way?

I'd like to write an application to manage a little web-shop using EJBs and MDBs as follows: * A java servlet who takes data from web application, i.e. the identifier of a client who wants to buy a book. * Before allowing this purchase i want to check if this client is not in my 'defaulter list'. * After this i'll be able to avoid/allow the purchase. Well, i though to do this: The servlet takes data from web client and sends it to a Topic, then Topic sends data to a Checker Bean that runs a method called 'checkClient' wich look for this client in a 'defaulter' database. If everything is ok, a 'true' value is returned to servlet Sounds more like a Queue than a Topic to me. Queues are for point-to-point messages and Topics are for Publisher/Subscriber (many receivers). Is this a good way to pose my problem? I know its possible to develope *the same* without MDBs, but, is there any advantage on using MDBs? in other words, how can i take advantage of MDBs? I'm not sure what you are trying to do, but this is my take on what you want. 0. MDB listens for messages on in queue 1. serlvet sends message to in queue with whatever should be checked 2. servlet waits for message on out queue 3. MDB.onMessage() called 4. MDB checks whatever 5. MDB sends message (true or false) to out queue 6. servlet receives message and proceeds I'd say that the advantage of MDBs is that they can be called asynchronously. What you want to do sound synchronous and while possible to do it just adds a lot of overhead. A session bean is easier and faster. To me it seems as though MDBs are useful for triggering some action that you don't want to hang around waiting for. For instance, you might want to send an email with an order confirmation and personally I wouldn't want to hang around in my process order session bean waiting for JavaMail to finish (after all it is talking SMTP to a mail server somewhere) so I would simple put a message in a queue and let an MDB deal with the sending of emails.

[JBoss-user] Various DB problems (with CMP)
Hi, Some Hypersonic problems in JBoss 2.2.1 out of the box that have been causing me trouble for a few weeks... I wonder if anyone can help me with them? 1) As I go on doing operations with CMPs (with lots of large Serializable objects or byte[] in the entity beans in question, in case that makes a difference) the JBoss-2.2.1_Tomcat-3.2.1/jboss/db/hypersonic/default.script file grows and grows, even if for example, I drop the tables. The default.data file never grows. How can I get the `log' flushed? Here, for example, id the current state of the hypersonic directory after inserting the same few MB of data a few times: drwxr-x--- 2 dhd ExNet512 May 14 00:24 ./ drwxr- 5 dhd ExNet512 May 10 22:51 ../ -rw-r- 1 dhd ExNet 12 May 14 00:24 default.backup -rw-r- 1 dhd ExNet 20 May 14 00:24 default.data -rw-r- 1 dhd ExNet 80 May 14 00:24 default.properties -rw-r- 1 dhd ExNet125300428 May 15 18:46 default.script 2) I cannot create records (entity beans), eg including largish Serializable objects or byte[]s, larger than about 32kBytes in total. Is there any way to fix that directly? At the moment I am fragmenting data across several entity beans, but that will make some things that I want to do, such as maintaining a live index in an object in a entity bean, usually held in memory but passivatable back to the db, spectacularly inefficient. 3) Even if I keep records shorter than 32kBytes, if I undeploy and redeploy the same (unchanged) EAR, on trying to read some entity beans back into memory, they are reported as corrupt, `not containing serializable data' in some ByteArray deserialisation routine inside Hypersonic itself I think. This means I usually have to reload lots of data each time I make even the most minor change to my EAR, which is very sad. All data is loaded through Java with no access by anyone else. 4) I intend to have several GB of data in my database in the end, with several tables/beans having up to millions of records each. Will that completely stuff Hypersonic? I am resigned to having to sort some of these problems by moving to a different DB, but I want at least to understand what's going on with Hypersonic and make it a little more robust and to last as long as possible.

That fixed my Problem on the W2K Machine, which i use most of the time for development, but not on the RedHat boxes, which I use to host the final Applications. Adding tools.jar to the Classpath makes it possible to run a tomcat 3.1.1 (older Version) without JBoss. since I installed all that Stuff out of the box, it should be no Problem to see the demo JSP's depoyed by Tomcat.

wrote: Toby - Well, I have a class with static utility methods such as: public static void closeConnection(Connection connection) public static void closeStatement(Statement statement) public static void closeResultSet(ResultSet resultset) which, back in the day had a little more utility for getting pooled connections for non-bean stuff - I just kept the close calls because it keeps me from having try/catch blocks in my finally blocks... anyway, my beans use JNDI to get the pooled connections now and I was continuing to use these static calls, but received rmi errors ( a la java.rmi.ServerException: Transaction rolledback:com/bebee/recommender/utility/DatabaseUtility ). So I removed the calls to these static methods and replaced them with Connection.close(), etc calls. This stopped the rmi errors. My conclusion here was that an ejb calling static methods is apparently a bad thing (makes sense since it is trying to circumvent the container, i guess?) No this should work. This is a pretty common practice. What was the rest of the trace? There may have been a prior exception that would tell us more. The next problem was that since I was used to using my utility methods (which checked for nulls being passed in) I grew lazy and closed things in no particular order which resulted in NullPointerExceptions when I did the following: conn.close(); preparedstmt.close(); // null pointer here Or some other exception, or nothing, depending on the driver. // interesting point to make here -- no errors on regular statements closed here, just prepared ones... seemes rather odd ( i would be interested to hear more about this) Hmmm. Statement caches? rs.close(); According to colleagues the 'proper' order for closing this stuff is ResultSet then Statement then Connection - so I will take them at their word. With some drivers it won't matter, but I'd do as you're doing. You might want to make your static helper (once we figure out what's going on with those) take all three (connection, statement, resultset) as parameters so it can do it in order. You'd still want other overrides, though. So in conclusion, I confiused the hell out of myself -- which is good every now and again.

Re: [JBoss-user] Problem making CORBA call
You might find that ORBs do some things that an EJB would be prohibited by
the spec from doing, but I'm pretty sure JBoss wouldn't stop them from
happening anyway.
I had originally figured that perhaps the ORB was breaking some rule, but was
unable to guess as to what that might be.
Are you sure that the IOR string is the same as you are using the Swing
client? Are you running these things on the same machine? Perhaps there
is an environment configuration problem. Are you using the same ORB? Are
you initialising the ORB the same way?
I'm 99% sure that everything is EXACTLY the same. I actually have the connection
logic in a helper class - CorbaManager. The IOR string is hard coded in the
class. I'm running both EJB and Swing client on the same machine. So, each
create an instance of the CorbaManager object - one works, the other doesn't.
I'll go and check for that extra 1% of confidence. Perhaps I'm doing something
different... but I really don't think that to be the case. At any rate, knowing
that it's not forbidden helps in now that I know there must be a problem
somewhere
Which ORB are you using? You might find that you're picking up an
orb.properties file in one but not the other, or something.
I'm simply using the OMG classes which are distributed with the JDK. The ORB
on the other end is a Forte server.. though that really shouldn't matter.
Anyway, keep us updated. I plan to port an application at work to JBoss
at some point, and we do a bit of CORBA, so I'm interested in how you get
on, at least.
I have no qualms with continuing to bug the fine people on this list, so no
problem. :)
I went back and checked... and found nothing that looked out of whack. As I
said earlier, I wrapped some CORBA calls in a helper class really quick. I
then create an instance of this helper object, have it connect to the CORBA
server, then use it as a call through for subsequent CORBA calls. The connect
logic (which works in normal client, but fails in a session bean) is as follows:
public boolean connect(String fileName) {
System.out.println(fileName);
String ior =
IOR:01001c0049444c3a436f726261534f2f436f7262615365727665723a312e3100b40001010a0077656273657276657200ed139c006652744501002b00536974652f436f726261534f5f434c302f436f726261534f5f636c302d436f726261536572766572534f0100010006002600436f726261534f5f636c302f436f726261534f5f434c302f436f726261536572766572534f000100;
//System.out.println(ior);
if (ior == null) {
connected = false;
}
try
{
System.out.println(1);
org.omg.CORBA.ORB orb = ORB.init(new String[] {ior},
null);
System.out.println(2);
if (orb == null) {
System.out.println(orb is null damn it
to hell!);
}
System.out.println(3);
org.omg.CORBA.Object obj = orb.string_to_object(ior);
System.out.println(4);
server = CorbaServerHelper.narrow(obj);
mediator = server.getCORBAMediator();
if (mediator == null) {
System.out.println(Crap!);
}
}
catch (java.lang.Exception e)
{
System.err.println(e);
}
connected = true;
return connected;
}
I have the IOR string hard coded in the class. I did this to avoid the I/O
issues within the bean, and to make sure that I was using the same IOR string
in both cases. In the Swing client, this method works find. It obtains a reference
to an object and stores it for future requests. However, when running within
a session bean in JBoss, I receive a NullPointerException. Within the console
on JBoss, I see the numbers 1, 2, and 3 get printed out - which means that it's
dying on the string_to_object() method. The IOR is not null. The orb is not
null (as I check for it directly above). So I assume the error is getting raised
from inside the string_to_object method.
Am I doing something really stupid?
Thanks,
-Dave

[JBoss-user] Jbuilder 4.0 Foundation JBoss2.2.1 HowTo Guide
Well after pulling my hair out for the last couple of days here is how to get JBoss and JBuilder as friends... Instructions for integrating JBuilder 4.0 Foundation or Higher with JBoss for source level debugging - Install the JBoss Server For the purposes of this howto, I installed teh JBossTomcat release version 2.2.1 into d:\JBoss-2.2.1_Tomcat-3.2.1. Download this from http://www.jboss.org and select the binary link from the page. This is a little confusing as it also contains the source (in the best interests of open source of course). - Create a JBuilder 4.0 Project I typically point this to the source for my EJB code. - Create a JBoss-Server library This is the most difficult part of the setup to get right, however once completed it does not need to be changed so you can setup multiple ejb projects and reuse this library (well done Borland) - Project / Project Properties / RequiredLibraries / Add... Add the following library entries to the JBoss-Server classpath (the order is crucual here). Pay specific attention to the log and tmp folders, faulure to put these in the Library class path will cause the classloader to spit out error messages, the most confusing of which is that /log.properties or /tmp.properties files could not be located. This is because the folders containing these files need to be in the classpath and the class loader complains. /$JBOSS_TOMCAT_HOME/jboss/lib/crimson.jar /$JBOSS_TOMCAT_HOME/jboss/bin/run.jar /$JBOSS_TOMCAT_HOME/jboss/bin /$JBOSS_TOMCAT_HOME/jboss/conf /$JBOSS_TOMCAT_HOME/jboss/lib/jaas.jar /$JBOSS_TOMCAT_HOME/jboss/lib/jboss-jaas.jar /$JBOSS_TOMCAT_HOME/jboss/lib/jdbc2_0-stdext.jar /$JBOSS_TOMCAT_HOME/jboss/lib/jmxri.jar /$JBOSS_TOMCAT_HOME/tomcat/lib/parser.jar /$JBOSS_TOMCAT_HOME/tomcat/lib/servlet.jar /$JBOSS_TOMCAT_HOME/tomcat/lib/jaxp.jar /$JBOSS_TOMCAT_HOME/tomcat/lib/webserver.jar /$JBOSS_TOMCAT_HOME/tomcat/lib/jasper.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/activation.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/awt.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/dynaserver.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/ejb.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/ejxeditor.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/ejxejb.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/ejxjaws.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/ejxjboss.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/hsql.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/idb.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/jboss.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/jetty-service.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/jms.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/jmxtools.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/jndi.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/jnpserver.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/jpl-util-0_5b.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/jta-spec1_0_1.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/mail.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/tomcat-service.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/jbossmq.jar /$JBOSS_TOMCAT_HOME/jboss/db /$JBOSS_TOMCAT_HOME/jboss/conf/default /$JBOSS_TOMCAT_HOME/jboss/lib/ext/log4j.jar /$JBOSS_TOMCAT_HOME/jboss/log /$JBOSS_TOMCAT_HOME/jboss/tmp /$JBOSS_TOMCAT_HOME/jboss/lib/ext/jbosssx.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/jbosscx-0.2.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/connector.jar /$JBOSS_TOMCAT_HOME/jboss/lib/ext/minerva-1_0b3.jar In the source tab for the JBoss-Server library point to /$JBOSS_TOMCAT_HOME/jboss/src. This is how JBuilder resolves where to find the source for stepping through the code. Without this step typically you will be able to step through the code but the Main.java will appear as Main.class. Set the main class to 'org.jboss.Main'. This is the main startup entry for the JBoss server. Also make sure that you set the working directory to $JBOSS_TOMCAT_HOME/jboss/bin cut and paste the following line and place it into the 'vm parameters' entry field (Project/Properties/Run) -classic -Dtomcat.home=D:\$JBOSS_TOMCAT_HOME\tomcat -Duser.dir=D:\$JBOSS_TOM CAT_HOME\jboss\bin -Djavax.xml.parsers.SAXParserFactory=org.apache.crimson.j axp.SAXParserFactoryImpl -Djavax.xml.parsers.DocumentBuilderFactory=org.apac he.crimson.jaxp.DocumentBuilderFactoryImpl The starup argument should be left blank with the above setting. If you want to run with the integrated tomcat you can put tomcat as the argument, howevre beware that you MAY need to replace the /$JBOSS_TOMCAT_HOME/jboss/conf/default with /$JBOSS_TOMCAT_HOME/jboss/conf/tomcat If the above steps have been done correctly, open up JBoss-Server.library, this is located in the folder you specified when creating the library. Typically this is C:\Documents and Settings\nt_username\.jbuilder4 or home directory on Linux.

Don't reference Minerva classes in your code. Just use javax.sql.DataSource.
If you don't reference to Minerva class, could you tell us what is the alternative to
cast the objref in PortableRemoteObject.narrow( objref, ? ) method ?

Also, you should use java:comp/env/ lookups, but that's not relevent here.

class here -- sorry if the readability is a little bad, tried to crunch it
all in )

Looks fine.
4) *** RMI ServerException Stack Trace ( this is thrown and the connection
is NOT returned to the pool )
This is thrown when I try to call DatabaseUtility.closeConnection(
connection ); (notice I catch _everything_ in that method) and is _not_
thrown in the DatabaseUtility, but seems like it is thrown on the attempt to
call the method.

Ok, you're missing out some details. Are you calling an EJB from a servlet?
You haven't mentioned anything about what this EJB is doing. What are you
doing with transactions? Are you getting the connection in the servlet
and trying to close it from the EJB or something?
5) *** NullPointerException stack trace (sorry for the log format) this is
thrown on the preparedStatement.close() call inside the bean at the end of
the transaction (which is directly after the call to connection.close() --
when I change the order of the calls, i.e. first close the prepared
statement then close the connection it works fine)
This is a bug. I'll look at this kind of fragility at some point.

Re: [JBoss-user] RE: Error 'closing' a pooled connection (addendum)
I think I had ClassCastExceptions back when I first started with these pools
and datasource lookups and the first fix I found was to use the Minerva
specific class, but I just changed my code to this and it works fine:
public class UPRBean implements SessionBean
{
transient DataSource ds = null;
public void aMethod()
{
InitialContext jndiContext = new InitialContext();
ds = (DataSource) jndiContext.lookup(java:/OracleDS);
}
}
of course, as Toby said:
Also, you should use java:comp/env/ lookups

All data is loaded through Java with no access by anyone else. 3) If I understand - U might want to have a separate instance of hypersonic running alongside - and use that - the separate instance for storing and the embedded jboss instance for smaller indexes (of indexes - perhaps) - just a thought ...

Try catching Throwable around the call to DatabaseUtility and printing the stacktrace. Toby. ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user
