EJB Converter App

I am trying to learn about EJB so I downloaded this tutorial (http://www.netbeans.org/kb/41/j2ee-tut/) and created the sample application ConverterApp which converts currencies to and from US dollars to Japanese Yen.
It uses NetBeans 5.0 and works fine but I have a question:
The main functionality of the program seems to be contained in an xml file called build-impl.xml.
This file creates the directories, compiles the code, creates the war files etc.
However there are a lot of other xml files in the project that NetBeans creates
and I am wondering what exactly do they all do.
Are they all required or could this i]build-impl.xml file be compiled with Ant and still work?

You need to specify the web client's enterprise bean reference, as described here:
http://java.sun.com/j2ee/1.4/docs/tutorial/doc/EJB5.html#wp80031
Redeploy the WAR after setting the reference and try again.

Converter app in Nokia Asha 308

Hey,
Just checked my phone and realised that there is no converter app (Length, Temperature etc) that used to be on other old S40 models. So should we download it seperately? Any link?
Solved!
Go to Solution.

Hello, Ahemdabad. Just to verify, you're unable to update the Converter app. Is that right? Is there any error message when trying to update it? Are you also using a Nokia Asha 308? If not, tell us the exact phone model you're using. BTW, make sure that you have an active and stable internet connection for you to update the app. Try accessing any website using the phone's browser to verify the stability of the connection.
We'll wait for your response.

Remove Default EJB/JSP Apps.

Hi,
I am wondering rather there are steps to remove the Default EJB/JSP Apps deployed in default installation.
I only need to run servelt and web caches.
Thanks,

Weblogic 5.1 uses an architecture that is very unique. Consider it the
exception, not the rule. You can NOT support a single deployment binary
with WL 5.1 and other servers.
The Weblogic 6.0 architecture is much closer to the others, and
significantly better than the reference implementation's architecture. In
6.0 you should be able to make a single app (EAR) that deploys to other
servers as well.

Hi,
I have written an application that has EJBs, and JSPs that invoke the
EJBs. It works on WebLogic 5.1.
I want to package this application up in such a way that it can be
deployed on any kind of J2EE application server.
Using JBoss, I discovered that the JSPs by default do not have access to
the interfaces supplied in the EJBs. i.e. I have to make copies of the
EJB's home and remote interfaces, and put them where the JSP files can
find them.
This messing about was not neccessary with WebLogic. WebLogic knew to look
in the EJB JAR files.
So my question : For compatibility, should I create multiple copies of my
EJB's interfaces, or is WebLogic's developer-friendly behaviour the
correct one?
Thanks, Martin.

Calling EJB from app client

Hello, everybody,
I'm very new at EJB and I'm trying to learn it.
I have created Enterprise Application using Netbeans IDE, I have EJB and APP client. What I want is to connect to my MySql database and get some info from table.
For e.g. Login and Password.
How can I call EJB from my client app which connects to my database and gets information I need?

What server you are using?
if you use jboss AS ,here is a simple Main class how to connect EJB and access ejb methods:
package com.david.ejb.client;
import java.util.Properties;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.rmi.PortableRemoteObject;
import com.david.ejb.domain.Person;
import com.david.ejb.domain.PersonRemote;
public class Main {
     public static void main(String[] args) {
          try {
               Context ctx = getInitialContext();
               Object obj = ctx.lookup("PersonSessionRemote/remote");
            PersonRemote pr=(PersonRemote)PortableRemoteObject.narrow(obj, PersonRemote.class);
            Person p=new Person();
            p.setName("david");
            pr.addPerson(p);
            pr.findPerson(1);
               // System.out.print(br.find(pk).getAuthor_name());
          } catch (Exception ex) {
               ex.printStackTrace();
     private static Context getInitialContext() throws NamingException {
          Properties p = new Properties();
          p.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.NamingContextFactory");
          p.setProperty(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
          p.setProperty(Context.PROVIDER_URL, "jnp://localhost:1099");
          return new InitialContext(p);
}Person is ant @Entity and PersonRemote is remote interfaces, to connect database you have to make datasource file at jboss-4.2.3.GA\server\default\deploy
simle mysql-ds.xml looks like this:
datasources>
   <local-tx-datasource>
      <jndi-name>some name</jndi-name>
      <connection-url>jdbc:mysql://localhost:3306/dbname</connection-url>
      <driver-class>com.mysql.jdbc.Driver</driver-class>
      <user-name>root</user-name>
      <password>root password</password>
      <min-pool-size>5</min-pool-size>
      <max-pool-size>100</max-pool-size>
      <idle-timeout-minutes>15</idle-timeout-minutes>
      <exception-sorter-class-name>com.mysql.jdbc.integration.jboss.ExtendedMysqlExceptionSorter</exception-sorter-class-name>
      <valid-connection-checker-class-name>com.mysql.jdbc.integration.jboss.MysqlValidConnectionChecker</valid-connection-checker-class-name>
   </local-tx-datasource>
</datasources>also at resources/META-INF directory you must have persistence.xml like this
<persistence>
     <persistence-unit name="SimpleEjb">
          <jta-data-source>java:/some name</jta-data-source>
          <properties>
               <property name="hibernate.hbm2ddl.auto" value="update" />
               <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
               <property name="hibernate.show_sql" value="true"/>
               <property name="hibernate.format_sql" value="true"/>
          </properties>
     </persistence-unit>
</persistence>

BPM Reporting Activity content extraction in ejb/enterprise app

Hello BPM experts,
I have a running BPM in our production system. And there are about 6000 users
who use the process.
The process has a reporting activity that collects all the possible failuers,
and successful event traces.
Now we want to build a controller app that uses jsps performing:
1. show all the data collected by the reporting activity objects.
2. show a list of all the process instances those have a status of suspended
3. and can cancel the processes by selection.
We plan to build the app based on ejbs those are accessed by jsps to
perform the 3 tasks mentioned above.
The reason that we want to build these apps is because the administrators
are system administrators and do not want to logon the NWAdmin gui.
So, guys, my questions are where do I find BPM apis, and other support
/ sap nw bpm dependency libraries / jar files ??
I highly appreciate your help and cooperations for this :-)
Best Regards,
Ajeet Phadnis

Updating my Adobe ID converted apps to trials...

After going to the Adobe Conference this year and receiving a year subscription to the Creative Cloud under my Adobe ID, things seemed ok until I updated my ID (also updated my password in ref. to the security breach) to another email. Unfortunately it appears that was an older Adobe ID of mine and now Creative Cloud is converting my status to 'TRIAL' on my apps. What is my fix for this, as my year's access to non-trial apps is now being cut short. Do I have to return to my standard CS5 apps and leave the Creative Cloud?

Small bump here. I tried changing my AdobeID back to the original at time of activation with no luck. Any help here would be great. Thanks.

Proper Converting Apps To Use For PC Users...

Hello all, I decided to create this thread because of all the content on converting being all over the place. This thread should only be used to describe how people converted videos, how they got it onto the ipod, and the programs they used. Some advice: I use Videora's Ipod Converter (http://www.videora.com/en-us/Converter/iPod/). It works perfectly and flawlessly with fast speeds. Use the SP/320x240/768kbps Stereo/128kbps option. If you need help, just repost here and I'll get back to you.

People all over the forums report QT Pro taking hours just for about 30mb and that is unacceptable.
H.264 compression does take significantly longer than MPEG-4 compression. QT Pro can do both. I ran a quick test to compare export times. Here's what I got...
Source video: foo.avi, 640x480, 82 sec play time
"Movie to iPod": foo.m4v, 320x240, 318 sec encode time, 5712 KB file size, good quality but gets pixelated in some motion sequences.
"Movie to MPEG-4": foo.mp4, 320x240, 67 sec, 3030 KB file size, very good quality and does not get pixelated in the same motion sequences.
So, I guess it depends on what's more important to you. The MPEG-4 output was about 4.7x faster than the H.264 output for the same source video. But, the H.264 video was almost half the size with better quality. Which is best for you? That's up to you.
Also, the h.264 format is said to not work properly on the ipod vid
From my tests, I haven't been able to get H.264 to work inside of an MOV container. It encodes fine, but iTunes won't let it on the video iPod. This is contrary to the iPod spec, which does say that H.264 is supported in an MOV container. It may be that I haven't found the right combination of settings for MOV. However, we have been able to get H.264 video to work inside of an MP4 container using the "Movie to MPEG-4" option in QT Pro. Also, the "Movie to iPod" option in QT Pro creates an M4V (not MP4) file with H.264 video and this definitely works on the iPod. So, I'm guessing the reports you're hearing are from people who tried MOV with H.264. The iPod can definitely play H.264 video, it just comes down to choosing a format and compression settings which work with the iPod. If you stray from the "Movie to iPod" option, you probably will create a bunch of videos that won't work. So, if you go this route, use a short duration source movie, because it takes quite a bit of trial and error to find the settings that actually work.
If you read the forums all over
Yep. I've read 'em. Lots of views out there. I'm trying to contribute actual test results, instead of opinions and speculation. I'm sure there's going to be lots of ways to get video on the iPod, and by all means use whatever method works best for you.

EJB + ADF app

Hi.
I'm using JDeveloper 11.1.2.2.0 and I'm developing "normal" adf application. Inside this application there is also project named Interface which uses EJB3 tchnology to communicate with outer world and outer world can communicate with my app.
If I call one method of my stateless session bean for first time (after deployment/restart of server) it works fine. Next time I want to execute that method I get error like:
Exception [EclipseLink-7197] (Eclipse Persistence Services - 2.1.3.v20110304-r9073): org.eclipse.persistence.exceptions.ValidationException Exception Description: Null or zero primary key encountered in unit of work clone [my.entity], primary key [null]. Set descriptors IdValidation or the "eclipselink.id-validation" property.This happens when I do particualar query (which is ok, for sure).
If I just restart server and reexecute same method and works fine.
For me it looks like there is caching enabled. Or something like that. I have also tried to disable caching with put property inside persistence.xml like:
<property name="eclipselink.query-results-cache" value="false"/>Without luck.
Does anyone experience similar problems?
Any ideas?
Regards

Set the entity class as
@Entity
@Cacheable(false)
public class entity{
}

Trouble looking up ejb (sun app server 8.1)

Hi,
I am using the below code to lookup a stateless session ejb
Hashtable env = new Hashtable();
env.put("java.naming.factory.initial", "com.sun.jndi.cosnaming.CNCtxFactory");
env.put("java.naming.provider.url", "iiop://127.0.0.1:3700");
javax.naming.Context c = new javax.naming.InitialContext(env);
Object remote = c.lookup("java:comp/env/ejb/TestBean");
com.mycomp.testing.ejb.session.TestRemoteHome rv = (com.mycomp.testing.ejb.session.TestRemoteHome) javax.rmi.PortableRemoteObject.narrow(remote, com.mycomp.testing.ejb.session.TestRemoteHome.class);I debug through the lines (using sun java studio enterprise), and find that I get a null pointer exception on the 4th line (while getting the instance of initial context). Is it a problem with the iiop port i am using ?
Thanks,

What video converter app for mac would you suggest to convert videos for ipad mini?

Just recently got myself ipad mini and want to fill it up with movies. i have some but they have wrong format. And i don't know which format is the best for ipad mini(

iPad Mini supports .m4v, .mov, .mp4, and some of .avi files with Motion JPEG (M-JPEG) codec.
Generally, you can choose to convert files to MP4 format using utilities like Handbrake, Format Factory, etc. They are all free.
I have get a PS3 and iPad 2 years ago, sometimes I need to convert files to AVI for my PS3, so I choose a professional converter called AppGeeker. (while handbrake only output mkv and mp4 format, and FF reduces amount of quality of video)
it works marvelosly for me.
