Adding Set of Session Beans generates client with wrong session bean names

Hi,
I am trying to import a set of session beans deployed on Sun Java Sever 8.2 using Netbeans 6.0. on windows XP.
The problem is that the imported set generated by the IDE has wrong session bean names and out of 8 session beans in the client jar only 6 are shown (and different 6 every time). Also the remote methods of one bean are associated with another bean and every time its a different set of bean clients generated.
I am really perplexed with this behavior. Any help on this issue will be highly appreciated.

An RMI/IIOP parameter type must meet one of thefollowing criteria:
It must be a primitive type, or it must implementeither java.rmi.Remote or java.io.Serializable,
or it must be an interface for which the runtime typesatisfies the previous criteria,
or it must be an array containing elements thatsatisfy the previous criteria.This tells you exactly what you need to do.

Model session not in sync with Http Session

Hi All,
I have an application developed in JDev 11.1.1.4 and we are not using ADF Security for login.
The problem occurring is randomly some of the LOV on my home page are getting null (having no data). These LOVs are populated using the values passed as bind parameter from the login values (basically HTTP session values at web layer). So i added a method in all the task flow to set the session value at the model layer (default method) . Also on each call to the Am Impl call i am setting the value in the HTTP session and then invoking the method, but some how what happens is the Model level session value is not in sync with HTTP session and the list gets empty.
Any inputs what i can do to get out of this prblm ?
thnk

In this case you need to overwrite the activateState/passivateState method of your am and store/reads the values from the xml structure you get as parameters to this methods.
For more detailed information check the docs http://download.oracle.com/docs/cd/E12839_01/web.1111/b31974/bcstatemgmt.htm#sm0495
By the way, this is nothing you need to open an SR on as it's working as designed.

Adding data file to the existing tablespace given wrong format file name

Hi
while adding the data file existing tablespace. i given wrong format '/dev/oracle/data/user_data_02' i miss the .dbf extension for this data file.
Alter tablespace ts2 add datafile '/dev/oracle/data/user_data_02' size 200m
the data file was created.
So i want to know. What will happen if the data file is wrong format?
Thanks in advance

it doesnt matter what you name the file. oracle will be able to use it. if you need to change the name to meet your naming conventions, then you will need to take the db down and rename the file at the OS level and then startup mount to rename the file at the DB level.
why are you puting files in /dev? Thats for devices.

Robohelp HTML 8 - Generating files with apostrophe in file name

Before I start, I have read this thread
http://forums.adobe.com/message/1062904#1062904 and several others, yet I still have questions.
Previously I used Robohelp 5x, which worked perfectly. Our user manuals are in MS Word and each have several topics that have apostrophes in the topic name (that are necessary in the topic). Robohelp 5x would import the Word Document without issue and create HTML files that automatically replaced the apostrophe with an underscore. All references (Index, TOC, etc) to those files also automatically changed to underscore.
Fast Forward to Robohelp 8.0.2 (yes, I have the update). Even if I go into the options and make sure "Use Underscores in file names" is selected - it no longer replaces the apostrophe with an underscore (though it does replace the spaces with underscores).
Locally, when I generate the online help (WebHelp) and put it on our local webserver - it works just fine. Even with the apostrophes in the file names and references.
However, when the WebHelp files are hosted at our server hosting facility, any links within the Webhelp to files with an apostrophe result in a 404 error. I have searched and searched to see if there is some kind of server setting to allow these special characters to be recognized in the file name but have not had any luck.
Per the link at the beginning of this post, the issue in that thread was resolved by changing the file name of the HTML files. I attempted to change the file name of the HTML files that RoboHelp created. However as far as I can tell there is no way to do this within RoboHelp 8. If I attempt to do it outside of RoboHelp 8, I need to import all of the "new" HTML files and all references (Table of Contents, Index, etc) now show broken links and need to be re-linked to this new topic. This is not an option. I have 12 user manuals that are updated on a regular basis and the renaming\relinking process would take forever.
Any help would be greatly appreciated.
Thanks,
-Noob

I was able to log into the server hosting facility and look at the html files themeslves.
It appears that at some point (between when I created them locally and now) all of the apostrophes in the file names were changed to "Æ". This blew my mind. And sure enough if I plug in the URL and replace the apostrophe with "Æ" the page shows up just fine.
From what I've been reading it looks like that may be related to the conversion from MS Word and "Smart Quotes". I'm looking into that now, but any help would still be great.
Thanks,

How can I set up Gmail on my iPhone with a different domain name?

I'm an ASU student so my email ends in @asu.edu. However its a Gmail account and I just got a new iPhone and I would really like to set it up through the mail app but it won't let me. Every time I type my email and password in the phone says: "The user name or password for "imap.gmail.com" is incorrect"...but I know it isn't. Is there a way I can do this?
Thanks!

This should work; one of my e-mail accounts is my own domain through Gmail. Make sure your username is set to your full e-mail address (like [email protected]) rather than just your username.
Did you set it up on your iPhone as an IMAP account, or as a Gmail account? It should work perfectly using the Gmail setting. It can work as IMAP, but you need to jump through a few hoops to get there.

OWB Generating databaselink with wrong schema

I’ve been giving read only account (ware_user) to a source database. When you deploy a location in OWB, it creates a database link. When i view the code for the mapping that uses this location, it is not specifying the correct schema (sac) name in the script. Is there a way to specify the schema name?
FROM "WAREUSER"."V_RSVAA_KVWSUP"@"REQLIV02@DWTST_TO_REQ_CONN" "V_RSVAA_KVWSUP_DWTST1653670",

Hi,
You can set the mapping configuration for the actual schema.
Right click the mapping, select Cofiguration, in the pop up window, find the source table, you'll see the dblnk name and schema name. If you're extract data from remote database, you can create the dblink in your target database use ware_user to access the data source. Set the actual schema name in your source database.
All these will overwrite your location regiestering information for this mapping.
Hope this helps.

Unable to generate Bean Managed Client project

Hello,
I am using JDeveloper 9.0.3 Production (build 1035).
For each of our Business Components projects, we create a deployment profile - BC EJB Session Bean, Session Facade (BMT).
Because of the way our application is organized, the default folder proposed for the BMC (Bean Managed Client) project is not suitable.
As it is not possible to modify the BMC project folder or name once generated (maybe here is a slight problem?), we decided to find a different modus operandi to get the same final result.
But, it seems that the only way to create the BMC project is from the very beginning, when the deployment profile is created, and with the default names generated by JDeveloper.
Maybe I am missing something.
Here are the steps I perform:
1. Specify an Application Server Connection (Standalone OC4J) to our development OC4J server.
2. For the BC project, create a Deployment Profile / Business Components EJB Session Bean.
3. For this deployment profile, choose to deploy to Oracle 9iAS EJB Container, using the previously created connection.
4. In the AppModules section of the profile, carefully reset the option "Create AppModule Configurations" after having selected the one AppModule defined in the BC project.
5. In the properties of our AppModule, in the Remote section, I activate now the option "Remotable Application Module" and I select Session Facade (BMT) configuration.
6. In the Target Platform section, I update the Client Project entry to fit our project's organization and press OK.
7. I return to the deployment profile settings and set the option "Create AppModule Configurations".
For my surprise, at this moment the BMC project is not created. Nor if I compile the BC project, or modify again the AppModule, or the configurations, or the deployment profile...
I even tried to quit JDeveloper, re-enter and re-do the same attempts, but useless...
Is there a way to create the BMC project for a BMT Session Facade configuration after having created the deployment profile?
TIA,
Adrian

Sorry, I think I over-reacted. In fact, the only real problem I have is that I cannot move the BMC project from the default project to another.
I already have some projects for my application (which I tested until now in local config) and I want now to make them remotable. The problem with the project that did not want to create the BMC-pair was that it had nothing to remote - no exposed method, nor for AM, nor for VO's ;o)
For a project that already has some remotable methods, the steps to perform are very strict when you want to make it remotable. You are right, if I first make my AM remotable and properly define there the path and name for the client project, I get the good results.
But, even in this case, I did not see any integrated way of moving this project (completely generated by JDev) to another folder. What I do is modify the project in the configuration properties, quit JDev and move the folder manually.
Thank you,
Adrian

Implementing Web Service with Stateless Session Bean

I have a web service that I've built using the WorkSpace Studio tools (create a WSDL, generate the Java code from the WSDL, fill in the skeleton methods in the service implementation class). This service is deployed as a web module within an EAR to WebLogic Server 10.0 and is working great as a web service.
I'd like to be able to also call the operations on this service via an EJB interface (from a different application on the same server). I followed the guidelines for adding EJB annotations to the web service implementation class (from [http://edocs.bea.com/wls/docs100/webserv/jws.html#wp215790]). I added the @Session annotation to the class, implemented javax.ejb.SessionBean, and added the ejbXXX() methods. This all makes perfect sense, and looked like it was going to work. However, WorkSpace Studio now gives me a compile error on the class that says "EJB backed WebServices are not supported."
A few internet searches for that error didn't return anything relevant.
It seems like I followed the instructions correctly. Is there a better way to build a service like this that is both a web service endpoint and a stateless session bean?
Thanks!
-Eric

Having separate EJB and web modules certainly makes things easier, but I have non-trivial (i.e. not feasible to copy) application logic that I'd like to expose with both a bean interface (for intra-application usage) and a web service interface (for public consumption).
I've tried starting with a "web application" WorkSpace Studio project and adding bean annotations. This produces the error I originally described. I also tried starting with an "EJB" WorkSpace Studio project and adding web service annotations. This fails at deployment time with errors about missing web service descriptors (the error is correct - the web-service-related descriptor elements are missing from the deployment descriptors).
The documentation explicitly presents this as an option (annotating a class with both web service and session bean annotations), but how does one actually make this work?

Hi,
I have found a way out by passing the reference of my EJB in the HttpSession object and using it inside the javabean..

Normally, if you are executing the client from the command line, you do not specify the classpath in a XML file (unless you are using ant or something similar). You can specify the classpath by using the -classpath option.
Try something like
java -classpath <path_to_jboss>/client/jbossall-client.jar;Betting_server.jar BettingServer
You can check the classpath in your client with the statement
System.out.print(System.getProperty("java.class.path"));

A simple problem with sateful Session beans

Hi,
I have a really novice problem with stateful session bean in Java EE 5.
I have written a simple session bean which has a counter inside it and every time a client call this bean it must increment the count value and return it back.
I have also created a simple servlet to call this session bean.
Everything seemed fine I opened a firefox window and tried to load the page, the counter incremented from 1 to 3 for the 3 times that I reloaded the page then I opened an IE window (which I think is actually a new client) but the page counter started from 4 not 1 for the new client and it means that the new client has access to the old client session bean.
Am I missing anything here???
Isn�t it the way that a stateful session bean must react?
This is my stateful session bean source.
package test;
import javax.ejb.Stateful;
@Stateful
public class SecondSessionBean implements SecondSessionRemote
private int cnt;
/** Creates a new instance of SecondSessionBean */
public SecondSessionBean ()
cnt=1;
public int getCnt()
return cnt++;
And this is my simple client site servlet
package rezaServlets;
import java.io.*;
import java.net.*;
import javax.ejb.EJB;
import javax.servlet.*;
import javax.servlet.http.*;
import test.SecondSessionRemote;
public class main extends HttpServlet
@EJB
private SecondSessionRemote secondSessionBean;
protected void processRequest (HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
response.setContentType ("text/html;charset=UTF-8");
PrintWriter out = response.getWriter ();
out.println("<html>");
out.println("<head>");
out.println("<title>Servlet main</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Our count is " + Integer.toString (secondSessionBean.getCnt ()) + "</h1>");
out.println("</body>");
out.println("</html>");
out.close ();
protected void doGet (HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
processRequest (request, response);
protected void doPost (HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
processRequest (request, response);
}

You are injecting a reference to a stateful session bean to an instance variable in the servlet. This bean instance is shared by all servlet request, and that's why you are seeing this odd behavior.
You can use type-leve injection for the stateful bean, and then lookup the bean inside your request-processing method. You may also save this bean ref in HttpSession.
@EJB(name="ejb/foo", beanName="SecondBean", beanInterface="com.foo.foo.SecondBeanRemote")
public MyServlet extends HttpServlet {
ic.lookup("java:comp/env/ejb/foo");
}

Bug#3200562: New Flex Session Id generated while disconnect with streaming amf channel
While invalidating session, make sure a new one does not get created.

Property Changed:

You're trying to do this directly in ActionScript without using Flex, correct?
The mxmlc compiler for Flex adds some registerClassAlias calls to map types between the client and the server. This will be missing if try to use the messaging code outside of a Flex app.
Take a look at the mx.utils.RpcClassAliasInitializer class in rpc.swc. This has a static registerClassAliases method that will do the class registration for you. You should just need to call this before running your messaging code.

Bug##3200562: New Flex Session Id generated while disconnect with streaming amf channel
On session time out, Flex Client is invalidated on the server side. It also results in Flex Session getting invalidated. In order to complete the client-server streaming connection handshake, the client ends up sending a CLOSE command. On the server side, for any work to be done, the MB first needs to creates a Flex Session (if none exists). After doing the necessary cleanup, the newly created Flex Session will also be invalidated. No stray Flex Sessions will left dangling...
