[JBoss-user] Initial release of xPetStore, an implementation of PetStore usingxDoclet
I've just released an initial version of xPetStore. xPetStore is a subset of Sun Pet Store application that uses xDoclet With xPetStore, you will learn: * How to create EntityBeans (with local and remote interfaces) * How to create SessionBeans (with local and remote interfaces) * How to create MessageDrivenBeans * How to use CMP 2.0, EJBQL and CMR * Generate deployment descriptor for different vendors For the moment, xPetStore works very well with JBoss. Im working hard to port it to JRun, but I'm having hard time to do it because JRun template files are out to date and I'm not a JRun guru. Any JRun guru here? your help is more than welcome. For other app server (websphere,weblogic,iplanet,pramati etc.), help would be more than welcomed! If there is interest in this project, would it be possible to add it into xDoclet distro as example app?

Re: [JBoss-user] Lookup MBean
Peter,
For use in your apps, the correct way is to get a reference to the MBeanServer
and invoke methods on the MBean by passing object name, method name, method
signature stuff to MBeanServer ref.
#1 for use when the calling code is running in same JVM as MBeanServer: This
is some simple code I wrote to access one of my own MBean from a servlet:
public class FileSystem {
public static void deleteFilesFromDirectory (String path, String[] excludedExtentions)
{
try {
Object[] args = new Object[2];
args[0] = path;
args[1] = excludedExtentions;
String[] argClasses = new String[2];
argClasses[0] = "java.lang.String";
argClasses[1] = "java.lang.String[]";
getServer().invoke (getObjectName(), "deleteFilesFromDirectory", args,
argClasses);
}
catch (Exception ex) {
}
}
private static ObjectName getObjectName () throws Exception {
return new ObjectName ("Tes:service=FileSystemService");
}
private static MBeanServer getServer () throws Exception {
return (MBeanServer)MBeanServerFactory.findMBeanServer(null).iterator().next();
}
}
#2 for use when the calling code is running in a different JVM from the MBeanServer
This is an example I wrote to access MBean from main.
public class Client {
public static void main (String[] args) throws Exception {
try {
// Set up jndi properties
Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
props.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
props.put(Context.PROVIDER_URL, "jnp://localhost:1099");
InitialContext ctx = new InitialContext(props);
System.out.println ("Got context");
// Retrieve the RMI adaptor, can see this in jmx console
Object obj = ctx.lookup("jmx::rmi");
System.out.println ("Got RMI Adapter");
ctx.close();
// Wrap it in a connector
RemoteMBeanServer server = new RMIConnectorImpl((RMIAdaptor)obj);
// add your code here to call invoke method on server just like above.
}
catch (Exception ex) {
ex.printStackTrace();
}
}
}
#3 for calling simple methods on MBeanServer from html. See implementation
of jmx-console.
Hope this helps.

Re: [JBoss-user] How to access datasource at java:whatever from another thread?
this kind of problem often is a result of having a jndi.properties file
that directs jndi lookups through tcp/ip availiable to the servlet's
classloader. Check your packages and remove any such files.

Re: [JBoss-user] [MainDeployer] deployment waiting for deployer: What does it mean?
Jdom comes with most if not all 3+ jboss versions. If you want to deploy
another copy yourself, and deal with the many possible duplicate
class/classloader issues, which are apt to make your usage fail completely,
remove the META-INF/*.xml file from jdom.jar which is confusing the jboss
deployment system.

RE: [JBoss-user] Open File limit under linux with BASH 2.05
Thanks Chris, ulimit -n 8192 only works if you are root. We've ran a script that counted the file descriptors for the processes owned by our jboss user and came up with a number like 9,100. So I don't know if bash counts unique files descriptor or all of them when we get the too many files open IOException. Jonathan Paul Cowherd Linux and Java Administrator Genscape, Inc.

Re: [JBoss-user] How to access datasource at java:whatever from anotherthread?
The original scenario (not written by me), was that a startup servlet
called a session EJB which started Quartz, then Quartz started jobs from
a pool of threads (I know this is theoretically not kosher since EJBs
are not supposed to do thread management). One of these jobs then tried
to access JNDI.
However, I have verified that even in the startup servlet (using Jetty
as the web container), I am able to load a context in the global
namespace, e.g.
Context cx = (Context) ic0.lookup("/queue");
works, but I am unable to load any contexts or objects in the java:
namespace, e.g
Context cx = (Context) ic0.lookup("java:/jdbc");
DataSourcet ds0 = (Context) ic0.lookup("java:/DefautlDS");
Both of the latter fail with an exception that the name is not bound. I
can see the binding are ok using the JNDI lister.
I have tried using both the defualt InitialContext (new
InitialContext()), and also one with jboss specific (jnp) settings,
h.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
h.put(Context.URL_PKG_PREFIXES, "org.jboss.naming;");
with the same results.
I've also verified that the 'Java2ClassLoadingCompliance' value is set
to true...

Subject: [JBoss-user] How to access datasource at java:whatever from another thread?
I am binding a datasource using oracle-service.xml, which uses
RarDeployment to bind the datasource to JNDI using the 'java:'
namespace. Unfortuntately I have an issue accessing this from a thread
started by a Quartz scheduled job, presumably because items in the java:
namespace are thread specific, and the quartz started thread doesn't
have a copy.
My jndi name is 'jdbc/Certification', so it being bound as
'java:jdbc/Certification', and I can verify this by using the JNDI
viewer in the jmx-conxole. I presume that EJBs are able to access this
namespace because it is copied for them on deployment, but when Quartz
creates the new thread, that thread is not created by the container, so
doesn't get a copy of the java: namespace, and can access only the
global namespace.
Am I missing somehting? Is there any way to access this namespace from
other threads, or bind the datasource such that I can get at it? Any
info is much appreciated.
Regards,
Colin

[JBoss-user] Problem with 2.4.9 and Oracle XA connection

Re: [JBoss-user] Entity Bean Performance Tuning Help (intersection)
That shouldn't be to hard once we add support for sub queries, but
unless it is supported by most of the major vendors (postgres, oracle,
ms, ibm), it wouldn't be worth the work.

What is an INTERSECTION query?
From postgresql-help:
Syntax:
SELECT [ ALL | DISTINCT [ ON ( expression [, ...] ) ] ]
* | expression [ AS output_name ] [, ...]
[ FROM from_item [, ...] ]
[ WHERE condition ]
[ GROUP BY expression [, ...] ]
[ HAVING condition [, ...] ]
***[ { UNION | INTERSECT | EXCEPT [ ALL ] } select ] ***
[ ORDER BY expression [ ASC | DESC | USING operator ] [, ...] ]
[ FOR UPDATE [ OF tablename [, ...] ] ]
[ LIMIT { count | ALL } [ { OFFSET | , } start ]]
I think it is used like:
SELECT personID from persondata where datatype=1 AND value="ln1"
INTERSECT
SELECT personID from persondata where datatype=2 AND value="ln2"
finds the persons registered with ln1 as datatype 1 and ln2 as datatype 2.
I think the obvious solution "SELECT personID from persondata where (datatype=1 AND value=ln1") AND (datatype=2 AND value="ln2") doesn't work, as it compares one and one row.
In this table, personID isn't unique.
Is it widely supported?
I suppose so in the major DBs, if it isn't a simpler solution to this problem (using just one SQL statement).
In addition UNION and EXCEPT should be implemented (if these are not possible to work around).

Michael Bartmann wrote: Dain, I could help defining the grammar; unfortunately I'm quite busy this week and on a long sought vacation next week, so you'll have to be patient with me. No rush; I won't be able to get to it for a while anyway. The current grammar for JBossQL is not exactly tiny, at least the JavaCC representation is a bit difficult to read due to the way JavaCC grammars model nested expressions. But the things we will have to extend work on a higher syntactical level mostly, as in UPDATE SomeEntity SET SomeField= which could use similar low level tokens as the existing grammar when doing SELECT ... WHERE SomeField= Agreed We'll also have to decide which features are to be supported; One thing to think about is resultset postprocessing: e.g. in the case of a container iterating over a resultset it _could_ do some postprocessing if there is no adequate sql equivalent of the eql query. Example: SELECT arcsinh(SomeField) ... with a database not supporting that function. This smells like "jet-engine" anyway; I would speak against such postprocessing. One reason is my original wish to support providing the generated sql to any SLSB, and the session would simply pump it into a jdbc driver without any knowledge about need for postprocessing. So are we speaking only of a transformation engine mapping eql/jbossql to db specific sql, as would suffice in the case of UPDATES, where there is no need to postprocess anyway? I have no plans to do any post processing. I also don't have plans for a real query engine. All I plan on writing my self is a cross compiler. If someone wants to write it, that would be cool. That leaves the problem of function support across all databases. My current plan it to simply throw some sort of unsupported function exception when the query is compiled (deployment or at runtime for DynamicQL). -dain --- This sf.net email is sponsored by: Are you worried about your web server security?

Re: [JBoss-user] TX Bug: Transaction failure not passed back to the client
Folks, I found my main problem. It turned out that I had a trigger on the Card insert which inserted a record in another table using a FK which at insert time was still null. I have two points to make: 1. The logging in the server just told me it was a SQL error, but it never gave any details. I had to change the org.jboss.resource.connectionmanager.LocalTxConnectionManager class to log the linkedException. Can we print the messages in all linked exceptions when they are logged? 2. I still don't know why the transaction can fail during commit and not send notification back to the client.

Does anyone know how to do it? I'm using XDoclet 1.1.2 Thanks Greg --- This sf.net email is sponsored by: To learn the basics of securing your web site with SSL, click here to get a FREE TRIAL of a Thawte Server Certificate: http://www.gothawte.com/rd522.html ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user --- This sf.net email is sponsored by: Are you worried about your web server security?
