Re: [JBoss-user] Obtaining UserTransaction from within servlet

[Ole Husgaard]

Hi,

UserTransaction support for stand-alone clients was
just recently added to CVS. You may have to grap
the latest CVS sources if you need this now.

When you have it, a simple lookup of "UserTransaction"
will do.


Best Regards,

Ole Husgaard.

Re: [JBoss-user] java.io.FilePermission on jboss tmp dir?

[Guy Rouillier]

Okay, thanks to all who responded via the mail list and directly to me, I've
got a working client.  The client is executed outside of JBoss from a
command prompt, so jboss.home is not available.  Here is what I found that
worked:

grant
   {
   permission java.net.SocketPermission "192.168.1.100:1024-",
"connect,resolve";
   permission java.io.FilePermission "\\H:\\JBoss-2.2.1\\tmp\\-", "read";
   permission java.lang.RuntimePermission "accessDeclaredMembers";
   };

So many questions :

(1) What is the 3rd permission?
(2) I still need help in understanding the 2nd permission.  Typically, JBoss
and a client will be on different boxes.  How can it make sense for the
client to need permission for a temp directory on a completely different
box?  The client is simply reading what comes out of its end of an RMI pipe.
The client shouldn't be reading any JBoss directories.

Re: [JBoss-user] Home and remote classes for EJB to EJB call

[Guy Rouillier]

I deploy in 10 different jars because different groups are developing
different components.  Life is easier if we let each group maintain
independent jars.  I tried the ejb-link tag in ejb-ref, but it said it could
not find the referenced jar in the application.  From this I'm inferring
that it wants everything in a single ear file.  Is that correct?  If not,
could someone give me a working example.  Here is what I currently have when
ejb DbRelay invokes ejb DbTester (does not work):

ejb-jar.xml of DbRelay:
 
ejb/guyr/DbTester
Session
guyr.DbTester
guyr.DbTesterHome
guyr.DbTester
 

jboss.xml of DbRelay
  guyr.DbRelay
  guyr/DbRelay
  
 ejb/guyr/DbTester
 guyr/DbTester
  

The call in DbRelay:

 DbTesterHome home = (DbTesterHome) new
InitialContext().lookup("java:comp/env/ejb/guyr/DbTester");

[JBoss-user] principal=null problem

[Khaled Aboudan]

Hello,
 
I wrote LoginModules for JAAS Authentication. 
Calling secured EJBs from a local client works fine. However, calling the same 
EJBs from a Tomcat causes a security exception stating that the 
principal is null.
 
I have seen this discussed in many different 
threads. But I still have not seen any final verdict about the subject. Some 
people suggested to use 'Tomcat Style login Interceptor' ...is this the way to 
go? Could someone explain why this happens? 
 
Thanks in advance for your help.
 
Regards,
Khaled

Re: [JBoss-user] java.io.FilePermission on jboss tmp dir?

[Scott M Stark]

A permission entry like:
  permission java.io.FilePermission 
"\H:\JBoss-2.2.1\tmp\deploy\Default\DbTester.jar\-", "read";
will not work because the policy file parser needs to see a \\ for each \ in a path 
string.
It is better to use the ${jboss.home} and ${/} properties in the path specification as
Vlada indicated to create platform/installation independent policy files.

The jboss.home property is automatically generated if it is not specified so that
you can write policy files without knowing what the deployment environment
looks like.

To determine all of the permissions that are required by a given configuration
its trivial to write a subclass of SecurityManager that simply logs what
permissions are being requested. Here is one I use:

public class TracingSecurityManager extends SecurityManager
{
private static boolean showStackTrace;
private static PrintWriter traceLog = new PrintWriter(new 
OutputStreamWriter(System.out));

public static boolean getShowStackTrace()
{
return showStackTrace;
}
public static void setShowStackTrace(boolean showStackTrace)
{
TracingSecurityManager.showStackTrace = showStackTrace;
}
public static PrintWriter getTraceLog()
{
return traceLog;
}
public static void setTraceLog(PrintWriter traceLog)
{
TracingSecurityManager.traceLog = traceLog;
}

public void checkPermission(Permission perm)
{
traceLog.println("Need: "+perm);
if( showStackTrace )
{
SecurityException trace = new SecurityException();
trace.printStackTrace(traceLog);
}
}

}

The reordering of the jar files may help uncover a solution.  

I am almost certain that the classes in jar files are loaded in a
sequential order.  If there are two classes with identical
package/name, the class which is encountered first, will be used
within the current execution environment.  This can cause cross jar
file dependency problems. The "No such constructor" seems to provide
evidence of package/class version dependency issues. 

?? ;) -- does this make sense?

all

Re: [JBoss-user] Running the interest sample as a Servlet does not work

[Scott M Stark]

The #1 cause of this problem is not configuring tomcat correctly.
Try using the binary bundle that include a correctly configured
embeded tomcat: http://prdownloads.sourceforge.net/jboss/JBoss-2.2.1_Tomcat-3.2.1.zip

[JBoss-user] Running the interest sample as a Servlet does not work

[Carlos Granados]

Hi!
I have been playing with JBoss for a couple of weeks, I installed and
configured JBoss+Tomcat and installed, built and run the Interest sample and
everything went OK. So I tried to run the Interest EJB from a servlet client
instead of a standalone client and got into trouble. I have looked into the
list archives and it seems that a number of people are having the same
problem. Many ideas have been floated around but I have not seen a final
solution, so I would like to provide as much information as possible to see
if someone can look into this. So:

a) The EJB is properly deployed since you can run it without problems from a
standalone client. The client looks up the EJB using JDNI, finds it and runs
it without problem. The EJB outputs a message on the JBoss console to
confirm that it has been run. The Jboss.xml correctly lists the appropiate
JNDI name which is "interest/Interest" and the JBoss log correctly shows
this EJB being deployed under this name

b) I transformed the code of the sample client into a servlet. Here is what
my code looks like:


import java.io.*;

import javax.servlet.*;
import javax.servlet.http.*;

import java.util.Properties;
import javax.rmi.PortableRemoteObject;
import javax.naming.*;

import com.web_tomorrow.interest.*;

public class InterestClient extends HttpServlet {

  public void doGet (HttpServletRequest request,
 HttpServletResponse response)
throws ServletException, IOException {

PrintWriter out;
String title = "Servlet interface to EJB";

response.setContentType("text/html");

out = response.getWriter();

out.println("");
out.println(title);
out.println("");
out.println("" + title + "");

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

try
{
   // Get a naming context
   InitialContext jndiContext = new InitialContext(env);
   out.println("Got context");

   // Get a reference to the Interest Bean
   Object ref  = jndiContext.lookup("interest/Interest");
   out.println("Got reference");

   // Get a reference from this to the Bean's Home interface
   InterestHome home = (InterestHome)
  PortableRemoteObject.narrow (ref, InterestHome.class);
   out.println("Got home");

   // Create an Interest object from the Home interface
   Interest interest = home.create();
   out.println("Create home");

   // call the calculateCompoundInterest() method to do the calculation
   out.println("Interest on 2000 units, at 10% per period, compounded
over 2 periods is:");
   out.println(interest.calculateCompoundInterest (2000, 0.10, 2));
}
catch(Exception e)
{
out.println(e.getMessage());
} finally {
out.println("");
out.close();
}
  }
}



I can build this servlet without problems and I can also run it, so it seems
properly deployed. But when I run it I get a NamingException, which is
generated by the lookup("interest/Interest") call. This is the same name
used in the standalone client, so it is not a question of using the wrong
JDNI name.

c) I recompiled the code of the jnp package to see if I could get more
information on what is going on. I found that when the method lookup is
called in the client in the NamingContext class, located in the
NamingContext.java file, a ClassNotFoundException is generated when the
lookup(Name name) method calls the lookup method of the remote server (line
355: Object res = naming.lookup(n);)

d) I also put some logging println lines in the lookout method of the
jnpserver (in file NamingServer.java) and I found that both in the case of
the standalone client and the servlet, the jnpserver is correctly called and
it finds the appropiate object. I put some println lines to display the name
being looked up and the object found and in both cases I got the same
information:
looking for interest/Interest
found java.rmi.MarshalledObject@53248168

e) So my hypothesis is that the naming server correctly finds the EJB, but
when it is sent back to the naming client, it is somehow corrupted or
something like that. This seems a RMI problem and I feel that I have run
into something too complicated for me, so this is the point to ask for help
:-)

g) My configuration: I am running JBoss-2.2 with EmbeddedTomcat 3.2.1 in a
windows 2000 enviroment with JDK13

Thanks in advance for your help!

Carlos

This is handled by the connection manager, so we need to know which 
connection manager you're using.  Please include the

[JBoss-user] Obtaining UserTransaction from within servlet

[Ed Swierk]

I need to start a transaction from within a servlet, make one or more calls
to entity beans, and then commit the transaction.  However I can't seem to
find a way to obtain a UserTransaction object using the normal JNDI name,
"java:comp/UserTransaction".

Browsing the namespace with JNDIView shows that UserTransaction objects are
registered within the namespace of session beans, but are not registered
globally.

Should I try a different JNDI name, or is there another way to get a
UserTransaction from JBoss?

Thanks,
--Ed

[JBoss-user] Problem with MySQL driver

[P H]

Hello, 
 
I've read the archives about how to set up the MySQL database pool,
but I'm still having problems. Once the pool is set up, the server
hangs. The last messages I see on startup are:

That's it. The system hangs afterwards. If I take out the JDBC pool,
everything is fine.

I'm using:

I ended up BMP-ing the field.. In a CMP bean I did not
reference the BLOB/CLOB field in ejb-jar.xml or
jaws.xml as a CMP field. Then I wrote persistence
logic in ejbLoad() and ejbStore() to persist the
fields (also I called ejbStore() in ejbPostCreate() to
save the field for a newly created record).. 


If you do this you can use standard JDBC to read and
write BLOBs (let me know if you need sample code)


Good luck!

Re: [JBoss-user] java.io.FilePermission on jboss tmp dir?

[Vladimir Blagojevic]

Hey,

Ok so when you say

grant {

...permissions...
}

what you are saying is that this block of permissions is given to classes
that come from location . Cool..

Since JVM running JBoss needs to read your application deployed in (/tmp/)
it makes read write requests on your file system in /tmp.

There is no physical client involved here. Only jboss and application
classes.

Ok , now try using this:

grant{

permission java.io.FilePermission "${jboss.home}${/}temp${/}-",
"read,write"
}

meaning all code being loaded from anywhere (including jBoss classes)can
read write in /tmp and its subdirectories. You don't want to be specific
about exact file here. I forgot if jboss.home was declared anywhere but
you can pass it as an argument to jvm I guess.

HTH,
Vlada

the jboss.conf file:


 
  


I suspect that my problem is with this configuration setting. Does
anything look wrong with the above configuration?

What do you mean client? JVM executing JBoss instance needs to read your
filesystems?  Do you allow it or not, there is no client in this story...

Try using substitutions -  ${jboss.home}\tmp for cross platform
independence. See java.policy and java.security files in your jdk distro.

[JBoss-user] java.io.FilePermission on jboss tmp dir?

[Guy Rouillier]

The following is a repost of a message I sent out about a week ago that
received no responses.  We are getting close to release, so this issue is
important to us.  Is everyone just taking the easy way out and using grant {
 permission java.security.AllPermission;};?  Has no one actually figured out
the permissions that are required?


I'm developing on Windows 2000 with JBoss 2.2.1.

As we are getting closer to shipping, I turned on security (more accurately,
I turned off my easy way out of simply granting all permissions to the
world.)  Using just a command-line client (i.e., no Tomcat), I first
received a java.net.SocketPermission which I resolved with the following:

   permission java.net.SocketPermission "192.168.1.100:*",
"connect,resolve";

Is there a better way of allocating this permission rather than opening up
all ports?  I started with just 1099, but then immediately hit the
restriction on the port created for communication.

But my current sticking point is the next error I hit:

Exception caught: java.security.AccessControlException: access denied
(java.io.FilePermission \H:\JBoss-2.2.1\tmp\deploy\Default\DbTester.jar\-
read)

I tried to resolve this with the following:

   permission java.io.FilePermission
"\H:\JBoss-2.2.1\tmp\deploy\Default\DbTester.jar\-", "read";

but got the same error again.  Two questions:

(1) Why doesn't the above permission address the error?
(2) I don't understand the required permission.  Why is it asking for read
permission on a JBoss temp directory for the client?  Notice that it has a
drive letter. This will be completely irrelevant when the client is run from
another computer (which I tried - it does indeed still ask for \H:\.)  I
haven't implemented any method security in the bean or any logon
requirements.

Everything works if I have the blanket all permissions.

Re: [JBoss-user] CMP + BLOB + ORACLE

[Steven Haines]

I ended up BMP-ing the field.. In a CMP bean I did not
reference the BLOB/CLOB field in ejb-jar.xml or
jaws.xml as a CMP field. Then I wrote persistence
logic in ejbLoad() and ejbStore() to persist the
fields (also I called ejbStore() in ejbPostCreate() to
save the field for a newly created record).. 

If you do this you can use standard JDBC to read and
write BLOBs (let me know if you need sample code)

Good luck!

RE: [JBoss-user] MBean access via JNDI - How to?

Marc,

Thanks for your reply.  This is great, I could use some help.

OK, if I understood correctly, your advice was...
...typing the interface for management and using the EJB
infrastructure to locate and talk to the object is THE OBVIOUS WAY TO DO IT.

Uhm, what does that mean exactly?  What is the interface for management and
what exactly do I have to do with it.  This probably makes sense to the more
initiated user, but this is my first time using JBoss.

|Is this not an appropriate job for an EJB?  If there's a better way to do

In fact it is the perfect role for an EJB.  Perfect.  Let me expand on this
statement.

Management: 3 tier, instrumentation, agent, connectors.  The instrument is
whatever you are managing (in your case the data flow service).  The agent
is the JMX server the MBeanServer.  Then there is the connector layer.
Let's focus on that layer.

For JSR77 we define the API of the agents we are managing (you can look at
the JMX stuff of JBoss for a lifecycle API for example).  The agent layer is
not standardized but at least in JBoss (and AFAIK weblogic) the agent will
be JMX.  Now the real question is the connector layer, how are the tools to
access the agents since JMX is not federated or remoted it is a purely local
construct.

The natural answer, that arose in the JSR77 scope is do it with EJBs (done
by myself and mad A :).  A had done the RMI Connector as one option but
typing the interface for management and using the EJB infrastructure to
locate and talk to the object is THE OBVIOUS WAY TO DO IT.  You don't have
to write any distribution code any registration code, you can use the
security code etc etc.  Finally for jsr77 I am toying with the ideas of
session vs entity.  Maybe there are a few things that you want persisted (a
history of the management exchange on that dataflow) and then the entity
framework can be interesting as you would plugin a "versioning" of it.
JBoss really really is built for that (a stripped down container conf will
be shipped for management with specific datastores etc etc)

In JSR77 we will probably name it in a special way admin/blabla whatever, so
that you can access the top node under a specific directory and navigate
from there.  You can do the same just give it the right EJB name and off you
go.

I personally don't think there is a better way, certainly not a simpler and
cleaner one.

I have experienced similar problems. I use 'scp' to copy the jar's over the 
network. Every once in a while, the AutoDeployer starts reading the archive 
before everything is in place.

I understand the AutoDeployer uses modified date (from the file system) to 
determine whether a file has changed. If this date is set when the copy 
procedure starts to write to disk, as it appears to do (I'm running Linux, 
kernel 2.4.0/ReiserFS), there is a discomforting possibility for a race 
condition.

In my humble opinion, either the AutoDeployer, or ReiserFS is broken.

If this is something that the AutoDeployer should fix, a simple delay 
wouldn't guarantee anything, the network could be slow, just to mention one 
possible situation.

One simple solution comes to mind:  If ZipException causes deployment to 
fail; wait; retry.   Repeat until OK, or a number of retries.

I have never done any patches to the source-code before, so unless someone 
asks me, I won't give it a try

[JBoss-user] KAWA and JBoss

[Bob Bartholomay]

Hi all,
    While looking over the JBoss 
source I noticed a KAWA (a java IDE with EJB support recently bought out by 
Allaire) project file and easily had all the JBoss source in the Kawa IDE to 
study. great.
    As those of you that use KAWA 
for EJB stuff know, there is built in support for weblogic, J2EE-ri and Jrun as 
EJB servers that you can start from within the IDE. There are ini files in the 
Kawa directory tree that hold the various configuration options for each of 
these servers.
 
My Question:
    Can anyone point me towards any 
info or How-tos on how to get JBoss setup as one of these Kawa servers. I played 
with the config setup in Kawa with little success.
 
Any help appreciated in advance.

[JBoss-user] Informix connection

[Jennifer Labit]

All,

I have Informix set up and working with jBoss2.2.  It would be nice to see
the website updated with this information as it took quite a bit of trial
and error to get everything tweaked and working.  Where should I send the
config information?

WOW! The performance gain is just amazing! 15 images get loaded and
transferred in less than a second, if the beans are still cached, in

Re: [JBoss-user] SUPPORT OF JBOSS --IMPORTANT-- PLEASE READ

[Todd Chaffee]

I would be willing to provide support.  I'm pretty new to jboss but was 
able to get the petstore example working with mysql and to get embedded 
tomcat working with virtual hosts and apache so I think I've solved some of 
the problems that come up quite often on the list.

WOW! The performance gain is just amazing! 15 images get loaded and
transferred in less than a second, if the beans are still cached, in
about 2-3 secs if not. Now I'll just have to optimize the caching
parameters...

RE: [JBoss-user] Home and remote classes for EJB to EJB call

[Schouten, Andreas]

Wy do You deploy the 10 beans in 10 jars? If You deploy them all into one
jar You can call all interfaces.

If You need them in different jars, check out the  tag for
ejb-jar and register the nessasary references to the container..

The reason is that since you are accessing the same bean from 2 different
transaction context (ie normally 2 different clients), the calls are
serialized (ie one goes on, the other waits until the first finishes). When
calls are serialized, you get the LOCKING-WAITING message, but this is
normal.

Probably the best thing you can do is to add a 
public boolean isModified()
method to your beans. 
JBoss checks the return value of this method and if false, skips unnecessary
DB accesses. The performance gain can be huge, on this list has been
reported to be up to 30 times (but of course depends on the cases). All the
above works if commit option A is used, which is the JBoss default.

Use Integer instead of int !

True. Look at how many interceptors are required to provide the EJB 
services. Of these, the transaction interceptor is taking the most time 
right now (I believe).

RMI does not do collocation detection.

I haven't read the new pdf in detail yet, but I don't believe that local 
interfaces will have much of an advantage over JBoss' optimized calls, 
because there will still be the overhead of interception to provide 
security, transactions, non-reentrency, etc.

[JBoss-user] LOCKING-WAITING - what does it mean? / Transactions

[Raffael Herzog]

I sometimes get LOCKING-WAITING messages when someone accesses my
site. Everything works as expected, but these messages are still
there.

The background: When someone accesses the site, the first thing to be
done is to determine the language. There are two lists and one set to
do this: The list of languages the user would like t have, the list of
languages that are registered in the server and a set of available
languages. So each request leads to a findAll() on the Language
bean. If someone accesses the site the first time, this means 17
requests (two frames and 15 images), all of which kick off a
findAll().

To make it more simple (this is on the top of my TODO list), I just
declared the transaction policy for *all* methods as "Required". Is
this the reason for these LOCKING-WAITING messages?


And while I'm at it: What's the performace gain to be expected if
I set the transaction policy for read methods (find*, get*) to
"NotSupported"?

Thanks, but... this won't work (or compile): you can't compare an int to null.

[JBoss-user] MBean adding a URL to common classpath

[Lennart Petersson]

Are there any hooks available to add/remove an URL to/from the common classloader (or 
more preferable a specific ejb's classlaoder)?

Why? Cause i need to dynamically extend an ejb session bean with extended logic 
deployed in a sepatete jar file. Having a separat directory wich an MBean is scanning 
to look for new/updated/removed jar files and then making them availble for the ejb 
session bean. And classes from these dynamically added jar files need to be 
downloadable to clients.

Looked at the WebServer's method addClassLoader()/removeClassLoader() without success 
but i might have missed something.

Thanks,
Lennart

Hi,
one way to solve this is by changing the getXX() method in your EJBean class for that 
field to:

public int getXX(){  
  if (XX == null)
XX = 0;
  return XX;
}

[JBoss-user] Null pointer/Server exception when int column null in db

[Jim Cheesman]

I'm getting a NullPointerException (wrapped up in a 
TransactionRolledbackException, in turn wrapped up in a ServerException...) 
when I try to read a column with null data in an int field. Is there any 
work around for this with a CMP entity bean, or is BMP the only way forward?



The db is DB2 over JDBC:ODBC, which I've finally managed to get working. 
The data is legacy and cannot be changed...

when i start jboss, i always get the error message :

it happens when jboss tries to deploy the tomcat-test.ear (I didn't change
anything)
when i deploy beans without a jboss.xml everything works fine, but when i
try to deploy beans which have a jboss.xml, i get the same error,
the beans worked already.
even after I installed jboss again, the error occurs
(I'm new in EJB and Jboss, so the beans are very simple)
