ThreadPoolExecutor in a JEE Application Server

Our application runs inside a jee application server.
We have tasks (implemented as a pojo) that need to be queued and executed by asynchronous threads.
We came across the new java.util.concurrent.ThreadPoolExecutor,
which seems to be exactly what we need.
However, as far as we know threads should be created ONLY by the jee application server.
Does this mean we can't use the ThreadPoolExecutor class in a jee application server?
If so what is the best practise for queueing tasks that need to be executed by a configurable pool of worker threads?
p.s
We are aware that JMS is also an option, but it entails a bit of an overhead in our case because the tasks are INTERNAL to the local application server ( so there is no need for messaging between 2 application servers).
thanks

JMS is certainly a solution to this problem.
JMX service MBeans are also a solution. they are a technology which was sort of (poorly) adopted into j2ee without a lot of specification about how to control them (just that they are there and can be used). on jboss, there are some proprietary extensions which make it very easy to setup a JMX MBean. i'm sure other app servers have similar facilities. anyway, MBeans do not have the concurrency restrictions of EJB's as they are singleton services, so that is where i would put such a worker thread pool.

Hi John,
One alternative is to use the EJB Timer Service. It allows you to create either a single-action
or periodic timer that will call into a stateless session bean (or MDB) when it expires.
Also, regarding the use of JMS, whether the processing of the message entails more than one
JVM or not is an implementation detail. There's no requirement that the JMS service itself
be located outside the application server JVM. If the producer and consumer are in the
same JVM it's perfectly legal for the implementation to process everything locally. In fact,
that's the default implementation in the Java EE SDK. Of course, there are more
sophisticated topologies that come into play for high availability and cluster solutions.

Possible bug in JEE Application Server Library MP?

The Beanspy Alert monitor reports alerts with missing data. See example below, specifically the {} returned parameters appear empty/incorrect.
Application server connection lost
Alert Description
Source:
Full Path Name:
Alert Monitor:
BeanSpy
Created:
The Health Service lost the connection to BeanSpy on port {2} to the machine {1} for the application server ID '{0}'.

So the next step I took was taking a deep dive into the JBoss.Monitored.Configuration.Discovery scripts and I found that the script tries to find and/or create registry keys about its discovered Jboss instances.
The key being created is: HKLM\Software\Microsoft\Microsoft Operations Manager\3.0\Modules\{GUID}\.\Script\PersistedDiscovery
In that key, values are stored called HTTP and HTTPS.
The persistedDiscovery key is deleted and recreated when you stop the Microsoft Monitoring Agent service and/or flush the health state cache. Thus manually adding the values is no use.
The HTTP and HTTPS values in a Jboss7 instance running domain mode cannot be retrieved because the port configuration is done at the Jboss domain controller and 'streamed' to the Jboss domain hosts.
In JBoss 5 instance however I see HTTP and HTTPS values being inserted into the registry. In a few cases incorrect information about ports is found and added to the registry.
In the Jboss discovery vbs I found the pieces for Jboss5:
' Get the HTTP & HTTPS ports of the JBoss 5 installation that runs a specific configuration
' Do this by adding the offset for the port binding to the base ports found in the XML file
' bindings-jboss-beans.xml located in <configuration>\conf\bindingservice.beans\META-INF\
Apparantly what is written in this file does not actually reflect the running config.
For Jboss7 it appears quite a bit more complex (especially running domain mode):
Step1:
' Get the HTTP and HTTPS ports for a JBoss 7 or Wildfly installation that is running in domain mode
' In order to get the HTTP Ports we must first retrieve the group that the server belongs too, as well as the port offset for each server
' These values both resiode within the host.xml file
Step2:
' We then look within domain.xml to find the profile reference based on the group name that we retrieved from host.xml
' After the profile reference we then can find the socket-bindings for http and https ports
While the information is there, these values are not added to the registry.
Thus, so far the script is looking in the right place to find the used ports for that particular Jboss7 Service, yet the monitor for the BeanSpy is not using that port to contact the BeanSpy.
My investigation continues...

JEE application - Maven repository server

I'm developing JEE application with Maven based build system. Planning to use some maven repository server(artifactory from jFrog or Archiva). My basic question is, none of them store the jars(artfacts we upload to repository server) in file system. They use Derby or providing other DB option. What is the value add going for DB to store the artifacts instead of file system? Is there any maven repository server based on file system? I hope file system pretty much sufficient to store & retrieve the artifacts. Any ideas/pointers? Thanks in advance for the help.

Any answers? Thanks.

Inserting data into MS SQL server 2000/2005 - JEE application

Hello everyone,
Looking at the Tutorial, roster, under ejb, it uses EntityManager and persistence to insert and access data from the, what i presume the Java DB. So i tried it with my applications. I get no errors when I insert the data. Only that it is not going into the DB, which is an external database, MS SQL server. Does this mean I can only insert and access data from the database through sql statements?
Help!
Thanks
eve

Hello everyone,
I have made progress on this. And if anyone requires more details check this website:
http://www.webagesolutions.com/knowledgebase/javakb/jkb006/index.html
Also please check your firewalls when dealing with external DB. For example, the windows firewall blocks the server from access MS server DB. So in an actual of fact, my above problem was working, only that it was probably directing data to the Java DB included in the application server 9.
The progress so far, is good. The persistence xml seems to create the Tables into the database. But it does not enter data into the database. Below is the error I get:

How to integrate Oracle Portal running on Oracle Application Server 10.1.2

I have an Oracle Portal running on a Oracle Application Server 10.1.2.
Portal is responsible ( along with OID ) for the users authentication and authorization.
There is a new JEE application that was developed recently, which the Portal users must have access to.
HOW can I put a link into a page of the Portal, that redirects the portal user to a new browser window displaying my new application?
HOW can this new application, running in a separate weblogic 11g (10.3.5) server, automatically authenticate with the same username/password previously authenticated when the user logged into the portal?
Any ideas?
I´ve already thought in a bunch of ways to do it:
- put a link into the portal with a sessionId, then when opening the new app, it automatically tries to use the same session. How can I configure this session id during the creation of the portal's page? How can I use it from the new app to use the same session?
- put a link into the portal with a userid, then when opening the new app, it automatically tries to authenticate using a different authentication provider configurated in WL, which points to Portal´s OID. In this situation, how can I ensure that the user is already logged in and the session has not timed out?
- Should I use OSSO?
- Should I use OAM?
Any help would be appreciated!
Murilo

Hi Murilo,
A portletized version of your J2EE app would probably have been ideal for your purpose as it would handle both authentication (through SSO) and session information (through Portal framework as the framework can pass session information to the provider/producer). This would require changes to the application however.
Easiest approach would be to use mod_osso to protect your J2EE application. SSO would then handle the authentication for your Portal and your J2EE application.
Thanks,
EJ

Apex Listener vs. Oracle Application Server... advantages?

Are there advantages to installing Apex Listener over using an existing Oracle Application Server instance to serve Apex applications?
We have an existing application server instance in production. Would introducing Apex Listener and the extra overhead be of any advantage?
Thanks in advance for your thoughts.

Hello "Portal Dude",
Are there advantages to installing Apex Listener over using an existing Oracle Application Server instance to serve Apex applications?APEX Listener introduces some additional features, such as Resource Templates, but lacks some others. Some people might want to migrate from OAS to another JEE Container that doesn't come along with a OHS/mod_plsql. Depending on the JEE Container, you could use AJP for load balancing, avoiding plain HTTP through a firewall, etc.
Would introducing Apex Listener and the extra overhead be of any advantage?The "extra overhead" may be smaller than you think. If you don't need the HTTP_Server component any longer, but can just deploy APEX Listener on the OC4J of your OAS, you might even save some bytes.
For several other aspects, there have been a few posts on that topic in the past:
{thread:id=1100122}
{thread:id=1555908}
{thread:id=1594158}
If there's anything you don't find in either the posts or the documentation, don't hesitate to ask.

Oracle Application Server 10g (Application Running)

Dear All Sir/Madam
It is my humble request that please tell me how to run Application on Application Server 10g.
I developed my Application in Oracle developer suit 10g (build internet appliacation), and I am using *10g database*.
Now please tell me the complete procedure who to configure oracle application server 10g on linux.

Hello Ghulam,
Notice that you can deploy different kind of applications within the Application Server framework, e.g. JEE applications, PL/SQL applications, Forms Applications etc. Based on what you initially mentioned, it seems that your have developed a Forms application. The above document reference refers to Application Server 10.1.3, which was a JEE / SOA release. You are probably better off with the [url http://download.oracle.com/docs/cd/B14099_18/web.1012/b14032/toc.htm]Forms Deployment Guide.
One note : Application Server 10.1.2.x is soon to be desupported. Consider to move to version [url http://www.oracle.com/technetwork/developer-tools/forms/downloads/index.html]11.1.2 !
Thanks,
EJ

Install and configure report service on Oracle Application Server 10g

i want to know how to install and configure report service on Oracle Application Server 10g Release 3 (10.1.3.1.0)
Thanks

the case is that we developed an ADF Application, so we want to deploy it on the latest version of Oracle Application server.
our application communicate with Oracle reports (run oracle reports from our Application) as there are no Oracle report products for JEE Application.
so if there are not report service that can run on Oracle Application Server 10g Release 3 (10.1.3.1.0),
what is the other choices that oracle supports that can help us in this case ???

If WCS is indeed installed on http://localhost:7101 and it can't see http://127.0.0.1:7101 then you should check to see if there is any restriction on the app server, OS, or firewall (though these requests probably aren't leaving the box) that could be preventing requests of this sort. You're seeing the event engine trying to talk to the event host.

Sun Java Systems Application Server 9 connection-pool ping error

Hi folks, I tried creating a javax.sql.DataSource MSSQL database connection pool with the jdts type 4 driver I got from sourceforge, and each ping operation I tried gave me the following error message:
Operation 'pingConnectionPool' failed in 'resources' Config MBean.
Target exception message: No PasswordCredential found.
My connection properties are:
user = sa
port = 1433
databaseName = FlyMyWayDB
serverName = digitanx-chalu
What does this exception mean, what are the possible causes, and how do I go about resolving it.
I will really appreciate any help, thanks.

As long as the JDBC Driver (jar file) for the connection pool(s) you want to create are in the app server's lib directory, you shouldn't have a problem creating both those and the JDBC Resources from the admin console (web app). So far, I am able to bundle my connection pools and resource connections inside my ejb module under "Server Resources" within my enterprise (.ear) application in Netbeans 5.5. When I deploy it, the whole thing works pretty sweet. I haven't gotten to the stage where I will want to migrate the jee application to my dedicated server yet, but I suspect that if my dedicated (remote) app server doesn't want to play nice with my netbeans when I try and set it up as a new server under my "Server Manager", then I'll likely try to simply deploy the .ear file from within the admin console, using the "browse" (for .ear) option (likely the better/preferred practice for production anyhow). Thanks for the dukes! My very first ones ever!

JEE MP: Authoring JEE Application Availability Monitor

So then how do we configure Expressions for Health State at this point in the Wizard, if we have such a long string value containing ALL of the stats? Anyone have insight into this?
Thanks!
I'm using the latest JEE MPs and SCOM 2012 R2, however I don't show the stats as a property on this MBean.

User management in Sun Application server PE 9

I need to be able to manage (create, edit, delete) users in my AS for a specific app.
Is there an API I can use to access the user information in the AS?
Can I create new users, edit and delete them?
If this is not possible:
Does anyone know how to manage user in JEE 5? It is very common to have to add users to an application and I'm wondering how do you do that. If you have to keep user information such as email, address info, etc.... do ou have to do this separately from the server?
Any hints? I'm lost... I must admit
Thanks and regards,
Mario

- deploytool was made available with Sun Java System Application server until version 8.2.
You can download SJSAS 8.2 from: http://java.sun.com/j2ee/1.4/download.html
From the above page, you can download either the standalone application server or (NetBeans 5.0 + SJSAS 8.2) bundle.
- deploytool was removed from SJSAS 9.0 onward. From version 9.0, NetBeans is the IDE offered for deploying apps on to SJSAS 9.0 (glassfish) and deploytool is not offered anymore. Please download NetBeans 5.5, which is the tool now offered by Sun for deploying to 9.0.
- It is not expected that deploytool shipped with 8.2 will work with 9.0. It most likely will not, even for j2ee 1.4 apps.

JSP and the Sun Application Server. Is it really nessecary?

Downloaded Creater 2, and love it. I really didn't realize how easy JSP is. Though I would be interested in knowing: Does the Sun Application Server needs to be running in order to use JSP.
Talking to my Hosting Provider, they have a plan in which JSP is included but the Sun Application Server is not. If I decide to get their JSP Hosting plan, do I truly need the Application Server to run my JSP forms and all the other great things that Creater 2 has to offer?
Thanks in Advance!

No you don't. You're app will run in any JEE server like Tomcat, Jetty, JBoss, Jonas, etc. If you are using EJBs, however, the server you choose must have EJB support.
