Help! JDeveloper 10g hangs.

JDeveloper has been causing me a lot of trouble today. It started when I was browsing some source code. I think I was trying to open the Javadoc of a system class when suddenly the IDE stopped responding. After a while I gave up, killed it and tried to start it again. Now it was hanging on startup. According to the progress bar on the splash screen, the startup process was finished, but nothing more happened. The main window didn't appear. I restarted my machine but this didn't make any difference.
Then I remembered that earlier today I checked for updates and downloaded and installed the ones that were available without restarting JDeveloper. One of the extensions was the Mac OS X addon although I am now on a Windows machine. It didn't think it would do any harm. But after the trouble started I thought this may be the cause. So I deleted the addon's jar file from the lib/ext directory. No effect. I deleted the jar files of the other extensions I remembered having downloaded today. No effect. Except maybe I have made things even worse. JDeveloper still thinks those extensions are installed so it won't download them again. I know this because I found out that if I wait long enough, JDeveloper will eventually launch fully. But the problem doesn't end there. If I'm lucky I can interact with it for several seconds and then it hangs again. Then after a long while it may become interactive again. And so on... Here is one thread dump I took while it was hanging during startup:

1. Re-test your connection from JDev to AS and it must success.
I suggest to create a new OC4J instance on AS and fill
the instance name on the dialog window while
creating AS Connection on JDev. i.e OC4J instance name (optional)
2. For JDev 9.0.5.x/10.1.2 using AS 9.0.4,
don't forget to install ADF Runtime Libraries on AS.
3. Make sure your AS support JDK/J2SE version as in JDev.
JDev 10.1.2 need AS to use JDK version 1.4.2_04-b05.
You can download it from http://java.sun.com/products/archive/j2se/1.4.2_04/index.html
and install it.
To cek your ORACLE_HOME/jdk/bin/java -fullversion

Help on Debug Mode in Oracle JDeveloper 10g/OC4J

Hi All,
     Presently I am using Oracle JDeveloper 10g Early Access version
          ADF Business Components     10.1.3.34.12
          Java™ Platform          1.5.0_05
          Oracle IDE               10.1.3.34.12
          PMD               JDeveloper Extension 1.7
          and OC4J.
I want to debug all the Java files between request submission and getting response from the server in j2ee application. This we can do in eclipse ide by putting break points where ever we require and running the server in debugging mode. But I don't know how this can be done in JDeveloper/OC4J. Please can any one of you guide me, if you are aware of it. Thanks in advance.

If you mean remote debugging the application on a stand alone OC4J then here is a basic how-to:

Hi,
As a first step to solving this, can I ask:
1. What version of the database are you using
2. Have you loaded the Client SOAP stack (see http://otn.oracle.com/sample_code/tech/java/jsp/loadjars.html )

I've been trying to get ADF to work with JDeveloper 10g but to no avail. I've followed the steps from the following link: http://www.oracle.com/technetwork/developer-tools/jdev/how-to-adf-faces-10gjdev-085657.html
the only thing that i fail to follow is in creating the library. I have only the adf-faces-api.jar and adf-faces-impl.jar but not the share-1_1_18.jar
I do not know whether this is creating the problem as my error message is not helpful.
part of the error msg:

I've been trying to resolve this by creating a new project but once i input adf tags the problem arise again.
Please help. Thanks!

Now that I've looked at the linked article...
That was showing you how to use a very early version of ADF Faces (a pre-release, in fact) with a very old version of JDeveloper. That document is nearly 9 years old.
Starting with JDeveloper 10.1.3, ADF Faces is "built-in"
And since JDeveloper 10.1.3.x, we have had both the JDeveloper 11.1.1.x and 11.1.2.x series released.
Why are you still using 10.1.2.x?

Drop Down Menu on Jdeveloper 10g - REVISED

Hello Gurus, I am using Jdeveloper 10g. I know that drop down menus are not supported in Jdeveloper10g/ADF and available from it's next release onwards which is Jdeveloper 11g. Hence, to develop drop down menus on a menu bar I am using HTML and Java script. The issue that I am facing - the horizontal menubar displays always on the top of the webpage overlapping other web page objects. This is not where we want to display the menu bar. Instead, it needs to show up somewhere on the middle of the web page. No matter what I do, it displays the menu bar on top most part of the web page. Always. Below is the code snippet. Any help in this regard is highly appreciated. Thank you for your time and efforts.

How to configure JMS queue on OC4J server. Development in JDeveloper 10G

Hi there,
I have to configure a JMS for an Asynchronous process in my Application which will be running in Oracle 10G Application Server. Development Environment is Oracle JDeveloper 10G.
I am facing a problem on how to configure JMS queue.
Steps Followed are:
in the <JDevloperHome>/j2ee/home/config
1. Made the new queue and connection factory's JMS entry in jms.xml.
2. Specifed the queue in oc4j-connectors.xml.
3. played around with application.xml
and tried all combinations, but the message producer always failed to lookup the queue.
Need help on the steps to follow so that the producer can post the message in the queue.
Also please help how to configure the MDB to listen to the queue.
Thanx and Regards
Subham

If you were dealing with Oracle 10g app server as opposed to standalone, I might be better able to help you.
One thing though, when you are configuring your MDB in the orion-ejb-jar.xml file, do not forget to specify attribute listener-threads, otherwise no matter how many beans you have in your MDB pool, only one bean will be listening to the queue. Many listener-threads equal to max number of beans in pool.

Problem in using JDeveloper 10g with JHeadstart

I am using JDeveloper 9.0.3 and jheadstart 9.0.4.5 and I would like to test jdeveloper 10g preview with JHeadstart.
So, I have downloaded the JDeveloper 10g to test it with my old application.
Having run the Jdeveloper for the first time, I realized that Jdeveloper
installed the jheadstart automatically and following message was shown in the message window :
E:\Software\10g\JDev10g\jdev\lib\ext\jheadstart\PrjWizard.jar!\META-INF\jdev-ext.xml

So I try to test one of my old application with this configuration. After Jdeveloper migrated my workspace and projects and business componenet
to the newer version, I run the application generator. It worked fine without any problem but after running the application, I got an error page showing
that my bc4j.xcfg is not in the path.
On the other hand, I found out that when I wanted to view my UIX pages, 2 dialog boxes appeared. The first one asked to upgrade
to UIX 2.2's new expression language syntax and the other which is on the top of the first one, showing that UIX runtime failed to render the page
with following detail :
javax.servlet.ServletException: No page broker found!

     at oracle.cabo.ide.addin.preview.BasePreviewThread.run(BasePreviewThread.java:79)
I think that I should have set some setting before use JHeadstart with JDeveloper.
Could anybody help me ?

Alex,
The document Sandra referred to applies to JDeveloper 10g preview (9.0.5.0). JHeadstart 9.0.4.5 will NOT work with JDeveloper 109 production (9.0.5.1).
We plan to release a new version end of april that is compatible with 9.0.5.1. See this thread for more info: JDeveloper 10g production, status JHeadstart?

Problem creating WebDav connection to review XML schema in JDeveloper 10g

I am trying to review some XML schema and cannot seem to create a WebDav connection. I entered all the relevant info and keep getting the following error :Testing connection...
Connection test failed: unable to connect
Unable to connect to WebDav Connection1 (http://localhost:8080/)
May require proxy to connect to the location,
when I tried to test the connection. The tips given in the help section didn't work either. Could someone please help me?

Thanks for your prompt response.
I had done that before yet, it still doesn't work.
Please, bear with this newbie, for a second.
I think it may be relevant to mention that I am trying to create a connection on my local network.
Had no problems when I try to connect to enterprise manager,or iSQL*plus console, or creating a database connection through Jdeveloper, or even to the HTTP server through the browser. I am using windowsXP platform BTW, if it makes a difference, and Jdeveloper 10g. When I try to create the webDav Connection it still gives me the connection failed error, .....

Any pointers will be appreciated.

Thank You very much for the solution. I had uninstalled the previous JDeveloper 10g installation and installed a new instance of the same. After which it worked without much of a problem.
However, my application requires to use MySQL database, so how do I tackle such an error. What was wrong with the connection? I mean MySQL instance seemed to work fine. Is there any version with which JDeveloper can work? Right now am using MySQL 5.0.? Please do advise.

Javax.naming.NameNotFoundException in Jdeveloper 10g

HI,
I just migrate my source code from Jdeveloper 9 to Jdeveloper 10g. Since then, all my codes do not work properly.
I cut and pasted from old version data-source.xml to 10g data-source.xml. However, when I run the project, I got javax.naming.NameNotFoundException:jdbc/mbciwebEjb not found. I check my data-souces.xml which in embeded-oc4j/config folder. The definition is there.
Can anybody help me?
Thanks
