Re: [JBoss-user] Blind Lookup

[Lucian Bargaoanu]

Well, just to test i've written a simple client which does

  try {
System.setSecurityManager(new
java.rmi.RMISecurityManager());
  }
  catch (java.rmi.RMISecurityException exc) {
  System.err.println("Security violation " + exc.toString());
  }
 Context ctx = getInitialContext();//standard stuff
 Object refEJB=ctx.lookup("FirstBean");

I need this client to be ignorant about FirstBeanHome. It works just as it
is on the host with JBoss ( first JBoss ).
It doesn't work on another host: java.lang.ClassNotFoundException:
FirstBeanPackage.FirstBeanHome.
On this other host I need to have JBoss installed ( second JBoss ). Probably
from within a service of this other
JBoss instance I will eventually do the loookup ( an alternative would be to
do it from an mobile agent (IBM aglet)
which arrives at this second host, so still a remote client ). But not yet.
I've read about the bug in JBoss (reported as item #424287) some time ago
and I thought that it might be the cause.
But I was troubled by the fact that it didn't work even when I've set
java.rmi.server.codebase to the path
of the jar with the bean on the first JBoss. A file:// path which is in the
local network so it is reachable from the second JBoss.

If you're not bored yet, the bigger picture.
A client makes a request for a bean to a JBoss instance ( through a custom
JNDI ). This one sends a mobile agent to
a few JBoss fellows to ask them about this name. The agent returns with a
list of servers wich have the name and
server load information. The first JBoss chooses a server based on the load
information and does a lookup to
return the reference to the client ( through the custom JNDI ). I cannot
have one JBoss instance knowing about
all the home interfaces of all its JBoss fellows.

RE: [JBoss-user] java.lang.Illegal.Argument Exception : object is not instance of the class

[Vincent Harcq]

I am pretty sure there is a problem in the instances pool somewhere, I also
receive something similar to that.
The trick is tio call any dummy remote method before calling remove.
Please help me figure out what happen :
Do you play with 2 session beans in 2 different ejb jar here ?
Thanks.

Re: [JBoss-user] Velocity & JBoss

[leigh]

Dear Toby,

Thank you for your reply.

Here is my content from velocity.properties

-
resource.loader = classpath
classpath.resource.loader.class = 
org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader
file.resource.loader.path = .

-
I made a template.jar under WEB-INF/lib.

But it still does not work.

Any special path need to reference in getTemplate?

I look forward to hearing from you.

Best Regards
Leigh

Please, when reporting exceptions, use copy and paste and include THE

[JBoss-user] JBoss/Jetty/JAAS Woes!

[Han-Shen Yuan]

Title: JBoss/Jetty/JAAS Woes!





I've seen this question posted, but alas no answers.


Per the instructions at http://www.jboss.org/documentation/HTML/ch11s78.html, I have been able to secure my Jboss beans using a stand-alone java program.

However, copying the exact same code into a servlet hosted by my jboss-jetty configuration (a stock configuration distributed on the Jboss site), it fails to work!   The behavior that I'm noticing is that the "ClientLoginModule" is called as in the case with the stand-alone class, _but_the_server_side_LoginModule_is_NEVER_ called when run in this combination.

I have tried the following:


1) Running bean and servlet in the same ear file
2) Running bean and servlet in separate ear files
3) Setting servlet java.security.auth.login.config to point to the SERVER auth file instead of the client (In this case, the server side login module is called, but the principal and roles are not passed to the bean).

If any of you have any ideas as to what might be happening, I would appreciate it greatly.  We really would like to run JBoss/Jetty in a production environment, but this problem is hampering that initiative.

Thanks in advance!

Re: [JBoss-user] XADataSourceLoader

[David Jencks]

Hi,
I found this problem back in early march and submitted a patch by email. 
Apparently in the move to sourceforge it got lost.  I've resubmitted it to
the sourceforge patch page. Patch # is 424399. Christian, you might add the
bug # to the patch if you submit a bug.  This patch is against 2.3 cvs but
the same modifications worked with 2.1.

My theory is that if you stop a XADatasource, you want a new copy when you
restart it.  At least the pools don't seem to be amenable to
reconfiguration.  So my fix frees the old source when the mbean is stopped,
and a new one is created when the mbean is restarted. Also, if the
connection can't be established when the pool is initialized, it's freed so
you can change the configuration and try again without restarting the
server. 

Thanks
david jencks

FYEO (For your eyes only) I'll give you an example - it's the
simplification
of our project.

Pretend that you have a "distributed workflow framework" where each
activity 
is a session bean (maybe from another server) with only one "business"
method run(). 
This method receives String as an input and returns String as a result.
And all activities have to implement this pretty simple RunInterface.

Now to the point. The framework allows users to add/remove/rent/whatever 
their own activities at run-time. By add/remove I mean "deploy/undeploy"
in our case.
For each client, this framework produced statefull session bean
"WorkFlowRunner".
The runner received a workflow descriptor and has to look up all
activities (from that descriptor) 
and run a given workflow. It doesn't have a clue what kind of activities
the user
wants and can use.

Sorry, if I didn't make myself clear. English is not my major.

Perhaps it's not. I'm about to slightly change the architecture and have
the activities either as plain java classes (to be wrapped in JMX
service)
or as JMX services itself. The container task will be run them and 
correctly keep results, user/account information and some other DB/TX
crap.

also you dont want 2 tags like below just 1 that lists all your drivers.  I

Looking at the TxInterceptorBMT code, I suspect that you are getting a
NoClassDefFoundError for the DatabaseUtility class.  Do you have that class
in your ejb-jar?

Try catching Throwable around the call to DatabaseUtility and printing the
stacktrace.

Toby.

Hi,

If not, I'll put everything in an external database.

A servlet calls the bean it only passes primitive types (int, float, etc)
into the bean, the bean gets its own connections from the pool and closes
everything itself - the servlet simply determines which bean to call and
gets form parameters to pass into the bean, the results are returned from
the bean and are formatted into HTML to display them. The results may be Map
objects, or primitive types

This is, in fact not a transactional bean. All it does is retrieves data
from the database and shoves it into a Map to return. It is a session bean
because some of the lookups are a little complex (do not map directly to a
table)  -- and some of them require multiple row lookups - which you cannot
do with entity beans.

my ejb-jar.xml reads as follows: basically straight from the interest
example:

...cut out ...

  AVR
  com.bebee.recommender.client.ejb.interfaces.AVRHome

com.bebee.recommender.client.ejb.interfaces.AVRInterface

com.bebee.recommender.client.ejb.bean.xaction.AVRBean
Stateless
Bean// my understanding is
that this mean I will handle transactions, if any

... cut out ...

Cast it to whatever you expect.  If you're looking up a DataSource, use
javax.sql.DataSource because that's the interface you want.

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:

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 ?

Don't reference Minerva classes in your code.  Just use javax.sql.DataSource.

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

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?

This is a bug.  I'll look at this kind of fragility at some point.

Yes, in the more dynamic case, where you are discovering the other beans
at runtime, this won't apply.  I can't personally think of a good reason
for doing this off the top of my head, but there's no reason not to just
use plain JNDI names in that case, IMO.

I don't know if it will work either.  If you need to make these decisions
at runtime rather than at deployment time then the deployment descriptor
is probably not the best mechanism and the spec be damned.

Sounds like yet another Minerva bug.  As this is now JBossPool, I guess
we should fix these.  Please log this as a bug at SourceForge and include
a complete test case, if at all possible.

I think so. Even web-apps (servlets, JSPs) are supposed to use java:env
namespace and have "deployment" descriptors.

Ok, two things here. First, what if I have to look for
several "hot-deployed" beans. I mean "several" and I
don't know exactly how many. Second, their jndi-names.
jndi-names are runtime parameters in my case.

BTW, your idea is very interesting, especially
in case of predefined names. I'm not sure that
it works, but... At least, I'll think about that.

Alex.

OK. You asked for it.

I will try to make this as clean and readable as possible:

1) jboss.jcml entries
2) connection creation
3) static methods for closing Connections/Statements and Results Sets
4) Stack Trace of rmi Error when calling the static methods
5) Stack Trace of NullPointerException on closing of PreparedStatement

This is thrown when I try to call DatabaseUtility.closeConnection(

call the method.

Oh, I thought you were getting a null back from string_to_object.  If you're
getting a NPE from the string_to_object call, then there's definitely a
problem with the ORB.

It would be helpful to see the complete stacktrace of the exception.

[JBoss-user] Minerva and ResultSet MetaData Bug?

[JBoss-user] Jbuilder 4.0 Foundation & JBoss2.2.1 HowTo Guide

[John P. Coffey]

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.

/$JBOSS_TOMCAT_HOME/jboss/lib/ext/connector.jar
/$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\\.jbuilder4 or home
directory on Linux.  Do NOT edit this file, I found several problems
manually editing this file and I am unsure why but I got several instances
of resoce not found exceptions afterwards.  If in doubt don't touch it!

If by "from another host" you meant "from another jboss instance", that
is
a bug. I experienced it a few month ago and recently it was discovered
and
filed as "the bug" at sourceforge.

Oops, sorry for the false alarm.  Your message caused me to check for
DTDs in deployment descriptor files and sure enough my partner in crime
had put a reference to the SUN ejb-jar DTD in our ejb-jar.xml.  Easily
fixed.  Not a bug.

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.

<>

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

I believe that it's the directory where you are when you run jboss.

I use Velocity's classpath resource loader.  Jar up your templates, drop
the jar into the lib directory of your war file, and add:

resource.loader = classpath
classpath.resource.loader.class =
org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader

No this should work. This is a pretty common practice. What was the rest

Or some other exception, or nothing, depending on the driver.

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.

Hello everyone,

I use Velocity as my web interface and JBoss as J2EE. In velocity you need

file.resource.loader.path = ./webapps/forumdemo/template

Where is the root directory relative to servelet running by JBoss & Tomcat?

Anyone knows how to solve it?

Thanks in advance.

[JBoss-user] RH7 JBoss221 Tomcat321 JSP Error 500 sun.tools.javac.main

[hossa hossa]

Thanks for the Help i already received. I installed
JBoss 2.2.1 with Tomcat 3.2.1 on a RedHat7 box and a
RH6 box. Also i installed it on a W2K box. on all
three boxes i get an error when I try to call the
Example JSP's. 500 sun.tools.javac.main.. That was the
result on all three machines. Servlets and JBoss
Example ran fine. I added
//lib/tools.jar to the clathpass. 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. Has anybody the same Problem and can give me a
hint what to do? I'm running a Sun JSDK 1.3.0_02 on my
RH boxes and on my W2K Machine.
Would be grateful for eyery help. thanks in advance

[JBoss-user] Various DB problems (with CMP)

[Damon Hart-Davis]

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.

Regards,

Damon

Please, provide details here. *Exactly* where did you receive this exception?
What was the stacktrace?  What code is in those static methods?

There is no problem with calling static methods in utility classes from
an EJB.

Ah, yes, this will give you problems because the statements and result sets
need to have references to the connection on which they were created.  You
shouldn't get an exception, though, it should just be ignored.

If you post the stacktraces then we can look into what's causing the NPE.

Yes, it makes a lot more sense to close them in that order, but the pooled
connections shouldn't be so fragile.

Well, only if you get some understanding to replace the confusion.

Re: [JBoss-user] RE: Error 'closing' a pooled connection (addendum)

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?)

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
// 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)
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.

So in conclusion, I confiused the hell out of myself -- which is good every
now and again.


Hope that helps clear it up.

Thats correct. You could resue everything by just renaming the bean in
the deployment descriptors and the jar-file.

As long as you message bean does the EXACT same thing (i.e calls the
same session bean or has the same message selector) you should not
create a new subscriber - because one of the great thing with MDB is
that you get multithreaded execution of your message listenerns (which
is verry hard, if not even impossible for topics with vanlilla JMS.

It is intended that JBoss use local copies of the DTDs.  If it's going
out to the 'net for them then there is a bug somewhere.  If you could
log a detailed bug report at SourceForge, including a complete example
that shows this, that would be really helpful.

If JBoss is modifying your jboss.jcml then you must be using an old
version.  This behaviour was removed before the release of 2.2.

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.

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.

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.

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.

Define "outside an entity bean." That code _should_ work from an entity 
or a session or a servlet/JSP running under embedded tomcat/jetty. You 
might need an empty jboss-web.xml to make it work from servlets.

It _will not_ work from outside of the VM that JBoss is running in.

Note that looking up under that name isn't necessarily portable accross 
application servers, and goes against the J2EE recommendations. You 
should bite the bullet and put resource references into your descriptors 
( (ejb-jar.xml && jboss.xml) || (web.xml && jboss-web.xml) )

[JBoss-user] JBoss archve search problem

[Norton Lam]

Is anyone else having problem with the jboss-user archive on GeoCrawler?

I keep getting:

Your search for 
htsearch detected an error. Please report this to the returned matches 

webmaster of this site. The error message is:
Unable to read configuration file '/bigassraid/htdig//conf/10767.conf'


for at least two weeks.

I've e-mailed the webmaster, but I don't get any response from him/her.

[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
scott

[JBoss-user] Datasource availability

[Norton Lam]

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.

Norton

Your client needs to have jbosssx-client.jar in its classpath.

[JBoss-user] JBOSS migration problem ...

[Cumps Jef]

Hi all, 

I was using jboss 2.0 FINAL and I am now migrating to jboss 2.2.1. I have changed all 
the config files as explained in the docs and I can succesfully deploy my application. 

When I try to create any of my beans however, I get the following output:

Am I missing something ?? Maybe a jar-file somewhere ?? I did everything (except for 
the configuration) just the same way as with the 2.0 version of jboss. Why isn't it 
working ??

If anyone of you can help me i would be REALLY grateful !!!

I think the problem is that RedHat ships a broken /etc/hosts file.  If you

[JBoss-user] JBoss and loading of DTDs -- How do I work offline?

[Chris Rossi]

Hello.  I was trying to do some development the other day without being
connected to the internet.  But I got stuck when JBoss started trying to
load DTDs.  Is there an easy way to ask JBoss not to validate XML files,
or a way to have it use local copies of the DTDs it wants?

[JBoss-user] Naming.lookup(String) vs. initCtx.lookup(String)

[David Ward]

Hi, all:

If I bind a JNDI object into JBoss-2.2.1_Tomcat-3.2.1
via a servlet in a webapp, I have no problem accessing
it via initCtx.lookup("foo").

However, what do I have to do config-wise to JBoss or
via syntax to be able to access that same object via
java.rmi.Naming.lookup("//localhost:1099/foo")?

"foo" does extend Remote and I did run rmic on it...

Thanks,
David

Java is not getting the instruction to connect to a remote host - it is
still trying to connect to JBoss locally.   Where are you providing the
remote host ip address?  I put it in jndi.properties and everything works
fine.

RE: [JBoss-user] NamingService initialization problems--ConnectionException

Scott, thanks for the reply.  I get an NPE when I delete the jndi.properties
file.

Here's the code for org.jboss.naming.NamingService.initService() in JBoss
2.2.1.  Without the jndi.properties file, the System.getProperties... line
gets an NPE.  With the jndi.properties file in place, the Context ctx = ...
line gets a ConnectionException.  If the jndi.properties file contains no
provider url, the Context ctx = ... line gets a ConfigurationException
saying "Provider URL missing."

Tim Taylor

public void initService()
   throws Exception
{
   // Read jndi.properties into system properties

   // buggy classloader that disallows finding the resource properly

Re: [JBoss-user] Oracle Connection Pool Startup - Null Pointer Error

[Guy Rouillier]

You get a null pointer exception when JBoss cannot establish a connection.
The most common cause is not supplying a valid userid/password combination.
Having the wrong Oracle instance name would probably also cause it.

[JBoss-user] Example Servlet Connecting to EJB using JAAS

JAAS?

I have a 'struts' war file with an Action that creates a 'WorkflowClient'
bean...Using a regular 'Swing' application everything works, but I get the
exception below when accessed from the Action...As you can see the user has

Re: [JBoss-user] Problem making CORBA call

[Dave Ortman]

Just a wild guess... I never assumed it would be correct.

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.

As would I.

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,

You can redefine a type-mapping on a per-column basis, see example 2 in

[JBoss-user] JBoss newbie needs help with installation!

[Frank Villarreal]

Hello all!

I have installed Jboss 2.0 standalone successfully before, but now I have
installed Jboss2.2.1 w/tomcat and receive the following error when I attempt
startup:

cd /usr/jboss-tomcat/jboss/bin

/bin/sh run_with_tomcat.sh

JBOSS_CLASSPATH=run.jar:../crimson.jar:/usr/jdk1.3.0_02/lib/tools.jar

EXCEPTION in thread "main" java.io.IOException: jboss.properties missing at
org.jboss.Main.main(Main.java:66)

I know the jboss.properties file is in the right place and present. I have
not modified the package downloaded directly from jboss.org. 

Has anyone seen this before? Can someone please point me in the right
direction?
Thanks in advance!

Re: [JBoss-user] jboss startup problems postgresql driver

[Michael Bilow]

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.

Hi,
can anyone tell me what I am doing wrong in this code block?  
I am trying to establish a connection to a topicConnectionFactory from

during the lookup() call.

Properties env = new Properties();
env.setProperty("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory");
env.setProperty("java.naming.provider.url", "localhost:1099");
env.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming");

jndiContext = new InitialContext(env);

topicConnectionFactory = (TopicConnectionFactory)
jndiContext.lookup("TopicConnectionFactory");


Thanks!

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."  Having a keyword index would allow
them to look under "Postgres" and produce fruitful results.

Re: [JBoss-user] Adding JDBC-driver

If you are using embedded tomcat there will be 2 jboss.jcml files. 1 in
conf\default and 1 in conf\tomcat

are you sure that you checked the same file each time and that if you
started jboss with tomcat that you are using the jboss.jcml file inside the
conf\tomcat directory

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

[danch (Dan Christopherson)]

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.

[JBoss-user] Adding JDBC-driver

[Bas Cancrinus]

Hi,

I'd like to connect JBoss 2.2.1 to a MySQL server.
According to the manual (chapter 3 - Introduction) I copied the 
driver-JAR to the lib/ext directory and I added an mbean-entry to 
jboss.jcml. When I start JBoss my entry is ignored (no extra [JDBC] 
output in log) and JBoss erases it from jboss.jcml.
Because this approach didn't work, I added my JDBC driver-class to the 
"jdbc.drivers"-value in jboss.properties. After starting JBoss, my log 
contained the output "[JDBC] Loaded 
JDBC-driver:org.gjt.mm.mysql.Driver", which is the added JDBC driver-class.

I have the following questions about the above:
- Why does JBoss behave like this towards the manual approach?
- Does my approach have any consequences for the functioning of JBoss 
compared to the manual approach?

Thanks in advance,
Bas

[JBoss-user] Resource Management

[connecstasy]

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.

Best regards, 

Jubin

RE: [JBoss-user] Using Xerces

[Xandy Johnson]

First, I am cross-posting this message to jboss-dev because I think it may
involve a development issue regarding class loaders.  At the minimum, I
think some explanatory material should be developed both for using other
XML parsers and for migrating to 2.2.x from earlier versions.  I am
willing to do this, but I know I won't be able to look at it at least
until next week, by which time I'm sure somebody else will have done
something.

Second, I apologize that this message is longer, less complete, and less
clear than I would generally hope, but I thought it better to send it than
to delay it until I have enough time, which may be never :-).

It seems to me that this problem relates to class loaders and the JAXP
mechanism for loading XML parsers, i.e. a factory method.  If
javax.xml.parsers.SAXParserFactory is loaded by the system ClassLoader
from crimson.jar, which is specified in the classpath given on the
command-line, then it will not have access to classes that are loaded
either from jboss/lib/ext, an MBean, or from the libraries of deployed
EAR files.  One solution, then, is to modify the scripts to put the Xerces
jar file in the classpath passed on the java command-line.  Then the
system ClassLoader will be able to see the classes.

However, this seems incomplete to me, since you can still only have one
value for the javax.xml.parsers.SAXParserFactory property, also passed on
the command-line.  I have not fully investigated this, but from a quick
glance at one of the former messages on jboss-user, it appeared that JBoss
itself would not work with Xerces specified as the parser.  If this is not
the case, I apologize to the developers for insinuating that it might be.
If it is true, then I think part of the solution is to modify JBoss so
that it can work with either Xerces or Crimson (or any other
JAXP-compliant parser).  Again, I can work on this, but not until at least
next week.  For those who may want to test this, put the Xerces jar file
in the classpath passed on the java command-line *BEFORE OR INSTEAD OF
CRIMSON* and specify -Djavax.xml.parsers.SAXParserFactory appropriately (I
think it may be the following)

set 
JAXP=-Djavax.xml.parsers.DocumentBuilderFactory=org.apache.xerces.jaxp.DocumentBuilderFactoryImpl
set JAXP="%JAXP% 
-Djavax.xml.parsers.SAXParserFactory=org.apache.xerces.jaxp.SAXParserFactoryImpl"

Note: UNIX users will need to adjust that to


JAXP=-Djavax.xml.parsers.DocumentBuilderFactory=org.apache.xerces.jaxp.DocumentBuilderFactoryImpl
JAXP="$JAXP 
-Djavax.xml.parsers.SAXParserFactory=org.apache.xerces.jaxp.SAXParserFactoryImpl"

Finally, the potential jboss-dev issue is this: is there some way that
beans or components (e.g Tomcat) could each be able to specify their own
XML parser and factory?  I'm not well-versed in the details of class
loading, so JBoss may already be doing the best that can be done given
Java classloading semantics, but I considered it worth asking the
question.

RE: [JBoss-user] select count(*) from ... during CMP bean creatio n

[David Jencks]

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

SV: [JBoss-user] INSERTING AN ALREADY EXISTING BEAN..... problem

[Lennart Petersson]

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.

Now i rest my case, until it creeps up again.

Hello
We want to start using the EJB 2.0 CMP model and have bought the MVCSofts
Persistant
Manager Educational Release. We have defined two local (same ear) Entity
beans with
a one-to-many relationship between those two. The deployment under JBoss
2.2.1 seems
to work fine, but when we try to add elements to the relationship we get an
exception.
See the dump below. Has anyone any idea why we get this exception ?

We are using MySql and all the tables has been created, and creating new
entities works
fine, but accessing the relationship fails.

Hello there

There is an omission in the version of org.jboss.tomcat.security.JbossRealm
that I checked out of CVS from the contrib/tomcat area. The principal and

The JbossRealm should implement a method to reset the principal and

[JBoss-user] customization of security

[Wei Ma]

I am trying to implement a "personalization agent" which acts like a real time
store clerk. The agent keeps track on the user's information such as account
balance and number of visits.

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).

Is there anyway  to implement this feature with JBoss without accessing
Database every time a request received?

thanks

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.
