Looking for BC4J EJB deployment example

Hi,
I am looking for an very simple example project for BC4J deployed as EJB, including table definition, BC4J source files, and EJB client source files. I have previously successfully deployed the BC4J to Oracle8i JVM and OC4J, but currently struck at how to write the client application. I would like to know how to call my own remote methods other than working with ViewObjects directly.
Help needed.
Regards,
Patrick.

Maybe this will help:
In JServer, ejb inactivity timeout is controlled by property jbo.ejb.txntimeout which value is 60 (secs) by default.
JServer properties file is deployed as oracle/jbo/server/jboserver.properties, you can get it from jbomt.zip (you should create the same directory structure and a project, say jServerProps.jpr, containing the file).
Edit the file:
jbo.ejb.txntimeout=28800
jbo.ejb.txntype=local
, then deploy it as Classes and Java Stored Procedures to Oracle 8i.
To see effective values of jServer properties you have to set jbo.debugoutput=console in file oracle/jbo/common/Diagnostic.properties - from the same jbomt.zip.
It's better to include the file in the above jServerProps project and deploy at once with jboserver.properties.

Issues in looking up a ejb deployed on glassfish from tomcat.

Hi all,
I have followed the steps mentioned in the EJB FAQ in the glassfish site and was able to lookup a remote ejb deployed in glassfish from a standalone client.
In case of standalone client, i set the appropriate jndi properties in the initial context as mentioned in the FAQ and added the 4 jars specified to the classpath of the application.
It all worked perfectly well.
But I attempted to do the same from a servlet running under tomcat.
I set the appropriate jndi properties in the intial context and added 4 jars specified in the lib directory of the war file.
But this did not turn out well and tomcat complained me with some servlet init errors.
Then i searched through the web and found this posting from you:
http://www.archivesat.com/GlassFish_Enterprise_JavaBeans_Developers/thread1399339.htm
Then i created a folder called "shared/lib" under TOMCAT_HOME directory in my machine and ran the same example. Wow.....miraculously the application ran well.
But i found that the "index.jsp" which i configured in the welcome file list does not appear now. But i was able to access the servlet without any problem. And the servlet was able to successfully lookup the ejb deployed in glassfish.
Then i thought, let me try to access the ejb from a jsf application.
Then i created a jsf application in netbeans 5.5.1 and tried to access the bean deployed in glassfish.
(Note: the jsf application runs in tomcat 5.5.17 which is bundled with netbeans)
OOPSS....
Tomcat now complains me that it cannot compile the jsp page..
This is the error i got...
org.apache.jasper.JasperException: Unable to compile class for JSP
Generated servlet error:
C:\Documents and Settings\james\.netbeans\5.5.1\apache-tomcat-5.5.17_base\work\Catalina\localhost\CityExplorer-WebClient1\org\apache\jsp\index_jsp.java:7: org.apache.jsp.index_jsp is not abstract and does not override abstract method getDependants() in org.apache.jasper.runtime.JspSourceDependent

Any ideas...
Can you please help me.
I've noticed that you were eagerly answering questions related to ejb lookup in many places.
I feel there is some potential compatability issue between tomcat and glassfish...
I request you to investigate on this and clarify the community with your response.
Thanks in advance,
James Selvakumar

BC4J EJB deployment ; testing deployment to 8i with client application

Hi,
Is there a way to to connect a java client application to a 8i deployed BC4J using the oracle.dacf.dataset.SessionInfo ? Can we do this using the JDev wizards - property inspector ?
(I've seen in the doc :"Testing a Business Components EJB Deployed to Oracle8i with a Code Client" but the given code
// setup application module variable
ApplicationModule appMod = null;
javax.naming.Context ic = new InitialContext(env);
ApplicationModuleHome home = (ApplicationModuleHome)ic.lookup(DeployedMod);
appMod = home.create();
does not contains any SessionInfo object.)
Thanks,
Xvc

Chris,
Perhaps you should be checking if the user you wish to deploy
EJBs to has at least JAVAUSERPRIV.
As SYSTEM
grant JAVAUSERPRIV to <user>;
Good luck

Doing a jndi lookup() for an EJB deployed on Glassfish v3

Hello.
I have deployed a Stateful Sesion EJB on a Glassfish v3 AppServer.
It is running under 'localhost' on my laptop pc.
I am also running a stand-alone java application on the same pc... it attempts to get a remote connection from the client-app to the Glassfish Server and then do a jndi lookup() to get a reference to my EJB.
here is the client source code:
public class LookupTest {
static Properties props = null;
public static void main(String[] args) {
try {
props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
     props.put(Context.PROVIDER_URL, "iiop://localhost:3700");
     Context ctx = new InitialContext(props);
     System.out.println( "the context is: " + ctx);
     System.out.println( "the environment contains: " + ctx.getEnvironment() );
     System.out.println( " ");
     // do a lookup.
     Object elementObj = ctx.lookup("SerialContextProvider");
     System.out.println(elementObj);
} catch (NamingException e) {
e.printStackTrace();
When I run this app, there are no Errors or Exceptions. It appears that the connection succeeds. But there are no EJB references in the context that is created. The only item that seems to be present in the context is an item named "SerialContextProvider", as noted in the return value from a list("") method invocation. Why can i not see the EJB within the context? Is my code wrong ??
Thanks,
Andy Jerpe
Edited by: user1169567 on Nov 28, 2010 12:12 PM

Ok, but the communication seems to be OK over the wire because if I use netstat -a I can see the ESTABLISHED connection with the server in the right RMI port.
TCP PORTAL35:1581 caapiranga:12405 ESTABLISHED
and then when I stop the instance in the OAS, the client shows an exception telling that the connection was lost.
An curious thing is that the ons.log doesn't log this connection ;/

Looking for a practical reparenting example.

Hello,
I have noticed a number of CS3 + /AS3 books mention how much
easier reparenting is now in AS3. (which may be true). What I am
struggling with is why anyone would reparent something in the first
place. Any practical examples of why someone would do this and why
it would be a prefered method would be greatly appreciated.
Thanks,

MATTANDIE,
> I have noticed a number of CS3 + /AS3 books mention
> how much easier reparenting is now in AS3.
It's not that AS3 makes it easier; it's that AS3 makes it
possible.
> What I am struggling with is why anyone would reparent
> something in the first place.
The example I tend to use -- only because I think it's the
easiest to
grasp, for programmers and nonprogrammers alike -- is a
jigsaw puzzle
application. Imagine a jigsaw puzzle done in Flash, in which
you drag
pieces around in order to construct an image (just like real
life).
Generally, this sort of thing is done with movie clips. The
easiest
approach is to use the native MovieClip startDrag() and
stopDrag() methods.
It can be a nice feature for snapped-together pieces to move
as a single
group. Doing so in AS2 means looping through those
snapped-together pieces
(keeping track of adding them, removing them, etc.) and
moving them all when
any *any one of them* is dragged.
Doing so in AS3 potentially means removing them from their
current
parent (say, the main timeline) and adding them to a new
parent (a container
just for snapped-together pieces). To move the whole group,
all you have to
do is apply a drag/drop routine to that one object.
> Any practical examples of why someone would do this and
> why it would be a prefered method would be greatly
appreciated.
I can think of other example, off the top of my head. You
might be
coding up a game in which numerous enemies are chasing the
hero. By
reparenting those enemies into a single group, you can run a
hittest against
the combined object to discern when the hero is coming too
near *any* of
them. When that happens, you could then determine which enemy
is the
closest, and remove that one entity from the group,
reparenting it to the
same timeline as the hero. In this way, you could focus your
hittest
routine on as few objects as possible, whereas in AS2 you
might have had all
your enemies "loose" in the same timeline as the hero. Your
hittests might
either be lesser optimised (always looping among all enemies)
or less
accurate (all in one group) -- but couldn't enjoy the best of
both worlds.
Does that help?

What I did to solve this problem was to
create a simple RMI remote object that
resides outside the database JVM and that
serves as a proxy EJB client for your java
stored procedure. The stored procedure can
invoke a method on the remote RMI object
which then looks up the EJBean's home
interface and invokes the relevant method on
the bean's remote interface, and relays any
return values back to the java stored
procedure.
Hope this helps,
Avi.

Client not able to access EJB deployed in Oracle8i

More complex Samples for BC4J/Jdeveloper

Hello oracle,
I'm looking for some more complex examples on JDev. and BC4J than available on the common resources (Auctions, hotel, ...). I finally found, that the .Com-Suite should contain a bigger JSP/BC4J application in source code called '.ComUnity Application'.
The bad thing is, that the link is broken (I've reported it to Oracle, but till now, no reaction). The documentation is available and looks quite interesting.
The download page is: http://technet.oracle.com/dotcom/ComUnity.htm
The link is: http://uksn281.uk.oracle.com/dc_software/Dot-Comunity1.0.zip
I'm really very interested in this package, so maybe you can fix this link or give me information, where I can find this application.
Thank you very much,
Ralf.

While we are on the subject of 'more complex BC4J samples', I would like to draw your attention to the new 'OnlineOrders' sample.
A good place to start is:
Help|Help Topics -> Tutorials and Sample Applications -> Tutorials -> Building Enterprise Applications with BC4J

Hi Mak_GK,
Sorry for the late answer.
Make sure that your client project has the following libraries:
JDeveloper runtime
Oracle 8.1.5 JDBC
Connection Manager
<your generated jar file from the EJB>
JBO Runtime
OAS Runtime
JBO OAS Runtime
Also, sometimes it helps to stop and re-start OAS after deploying your EJB.
