Can I deploy the session bean to 9i in the JDeveloper3.2

dear ONT
My JDeveloper3.2 can't find the method to deploy the session bean to 9i.
sk

I'm not sure that's entirely correct.
Personally I run both EJBs and servlets/JSP in OC4J. OC4J has all the 'web' features of IAS, including full SSL support.
From a speed perspective, running the EJBs and web components in the same container will give you a huge benefit.
Also I'm not sure what you mean by "you can't deploy EJBs into OC4J yet" - I do it daily? ;)

How can I set a Session bean timeout

Hello !
How can I set a Session bean to time out eg. 48 hours ?
Thanks
Uiloq Slettemark

For stateful session beans you can use the timeout attribute in the orion-ejb-jar e.g.
<session-deployment timeout=1800 ..>
this is specified in seconds and Default Value: 30 (minutes)

Im having what appears to be the same exact problem (Im getting a NPE and same error message). Did this get resolved? Im using xdoclet as well ... Here are the respective deployment descriptors that are getting created via xdoclet ...

May i use the session bean like this, if i dont want to use the data access object
may i use this...

Hey it apperars to me like heero82 is using session facade and all he has to do is use session bean to make one business call on session bean. Now if u say it is not correct then i would like to know the better way to doing so.
I can imagine one ways is use business delegate. Just make new of java class in jsp and let that java class do lookup and delegate the call to session facade.
Let me know inpout on this

Error while adding a new method to the Session Bean

Hello everyone. I'm using jdev 11g, ejb, jpa & jsf. Everything works fine. But when I try to add a custom method to the Session Bean, I'm having an error.
Here is my steps:
1) I added a new method to SessionBean.java. Something like this:
public void Hello() {
System.out.println("Hello!");
2) Then using Structure palette I exposed this method through Local interface and created data control
3) Finally, I made a command button binded to this method (just droped it from DataControls.dcx to my page)
When I start the page and click the button, I'm having the following error:
Error 500--Internal Server Error

... (I've truncated the log because there is nothing important in the missing part)

Yes, I have binding in the page def. Everything is correct there:
<methodAction id="Hello" RequiresUpdateModel="true" Action="invokeMethod"
MethodName="Hello" IsViewObjectMethod="false"
DataControl="PriceServiceLocal"
InstanceName="PriceServiceLocal.dataProvider"/>
I've droped the method from the Data Controls panel

Can anyone tell me how the session expires once we logout the page?

can anyone tell me how the session expires once we logout the page?
After logout ,if we click back button, it wont goes to last page,please explain how to write a code in jsp?

When we click logout the page redirects to logout.jsp or sevlet, there
the code for removing the attributes and invalidating the session is written. and then redirect the page to other page
Do You want some code???

Get the session trace files and also the TKPROF reports for storedprocedure

Hi ,
I am trying to find out the bottlenecks on a storedprocedure, which does a insert into a table, where the target table has lot of indexes/constraints, so i want to see, which indexes/constraints is causing the problem. so in order to do I want to get the session trace files and also the TKPROF reports to see the bottlenecks for a oracle stored procedure,
Could you please give us the list of steps to get the tracefiles and tkprof reports.

I understand it would be too much to expect you to actually Read The Fine Manual
I am using bulk collect for all in my storedprocedure to insert the rows into a big table. In order to perform analysis on this bulk collect which tool will help me to identify the bottlenecks .
I want to compare background session properties for both runs (like inserting the data with indexes/constraints vs without indexes/constraints). please let me know..I am willing to bet you the problem/slowness is on the SELECT side & not the INSERT!

What makes the session database so scalable in the Enterprise Edition?

What makes the session database so scalable in the Enterprise Edition?
How does it avoid becoming a bottleneck?

If you are enterprise customer then Sun has a good program called ASCSP program whereby they answers your architectural questions. They also help to give an estimate of the hadb nodes etc as per your requirements and shall give you performance tips to scale it . This might mitigate your scalability issues.
Hope this helps !!!

Can't deploy a SINGLE bean in weblogic 6.1 SP2 w/o application reload

Anyone know how to update a single bean in an application without
redeploying the entire application?
We have a project containing 101 beans (session and entity) and 372
jsps which we are deploying on weblogic 6.1, SP2 as a single
application. The project is deployed in an exploded directory format
as follows:
trader/
META-INF/application.xml
lib/
third-party.jar
third-party.jar (etc.)
SessionBean.jar
EntityBean.jar (etc.)
trader/
WEB-INF/web.xml
META-INF/MANIFEST.MF (contains Class-Path: entry to lib dir)
jsp/html/gif's reside below this point.
Each bean jar has a META-INF/MANIFEST.MF to resolve third-party
library dependencies through the use of the Class-Path entry.
When we we try to update a single bean's implementation, the
entire application reloads, which can take between 10 - 30 minutes.
We have tried using the weblogic.deploy tool as well as undeploying
and redeploying the bean from the console. In both cases, the
entire application reloads.
When we use weblogic.deploy, we've tried the following:
weblogic.deploy
-url T3://localhost:7001
update weblogicpwd trader ~/trader/build/SessionBean.jar
and
weblogic.deploy
-url T3://localhost:7001
-component SessionBean:srvr1
update weblogicpwd trader ~/trader/build/SessionBean.jar

Hi,all
I create a stateful session bean in jbuilder 7 and deploy it to weblogic7,it

How to deploy a session bean in Weblogic 9.2

Hi,
Can anyone please point me to the procedure of deploying session bean on weblogic 9.2. My operating system is Fedora 5. Please let me know the steps as i am very new to EJB.
Regards,
Sanjeev

I looked for this information in ServletConfig, in ServletContext, in JVMID
ServletConfig or ServletContext do not have anything (at least I do not see anything),
The newsgroups recommend the following code
public static String getLocalUrlString()
String urlString;
JVMID jvmid = JVMID.localID();
urlString = jvmid.getHostAddress();
weblogic.rjvm.Protocol proto
=weblogic.rjvm.Protocol.getDefaultProtocol();
int port = jvmid.getPort(proto);
return urlString + ISoapConstants.SCHEME_DELIMITER + port;
I also tried
weblogic.rjvm.Protocol does not exist in current version, and I did not get any real information inside JVMID
Also tried JVMID.localID().ports(), which returns null
System.getProperty("weblogic.system.bindAddr"); or weblogic.system.listenPort property,
getProperty returns null
Tried also another approach from the newsgroups - JwsContext.
/** @common:context */
JwsContext context;
String myPort = context.getService().getURL().getPort();
String myUrl = context.getService().getURL().toString();
context is null
None of them worked.
Do you have any other ideas?
All those ideas I found in the newsgroups were to the previos version(s) of weblogic - up to 8.1. I have not found anything specific to 9.2

JDev 10.1.3: Problem deploying a session bean to embedded OC4J

JDeveloper 10.1.3, TopLink, OC4J, WinXP, java 1.4.2_05.
I used TopLink to create a set of Java objects from a DB Schema, then created a simple Session Bean to read some of the objects. Everything compiles fine.
JAVA_HOME points to the JDK (not JRE) and CLASSPATH is empty (undefined).
When I try to Run my session bean in the jdeveloper embedded oc4j, I get this message. Thanks in advance for your help.

Does the EJBdeploy in some other server?

Unable to deploy stateful session bean in weblogic6.1

Hi there, I am trying to deploy an OrderSession.jar into weblogic6.1 sp 5. But it keeps throwing errors whenever I install the jar file. Following is the error message received. Can someone help me what causes this problem and how to solve it? Thanks!!
I have copied part of the error messages as it is too long. Hope the message helps. There are 3 sections of it.

Try unpacking the jar using a compression tool like winzip or any other tool and just check if extracted classes files are in the same package hirerachy as u have coded if not that is would be the problem

Can I deploy the session bean to 9i in the JDeveloper3.2
