JDev 10g Design Bug

I have a problem With this bug every time i click on design view on JSP files or java files. As a result i get this Java Null Pointer exception

Can you send the source of your JSP and let us know which JDeveloper version are you on 9.0.5? 10.1.3?

Bug: Jdev 10g - templateDefinition won't allow expressionLanguage setting

I've been migrating a set of pages from Jdev 10g Preview to Jdev 10g Production. I've got a UIX template (.uit) file with a templateDefinition like this:
<templateDefinition xmlns="http://xmlns.oracle.com/uix/ui"
xmlns:ui="http://xmlns.oracle.com/uix/ui"
xmlns:data="http://xmlns.oracle.com/uix/ui"
targetNamespace="http://www.paslists.com/pas/templates"
localName="pasPageLayout"
expressionLanguage="el">
I get the following in the structure window:
Errors(1)
--- Attribute expressionLanguage not defined on element templateDefinition
Can anyone help with this?

I've managed to fix this myself, after reading about all the migration issues. It seems that the migration process copied some settings that caused Jdev 10g Production to map to some of the prior Jdev XML schemas and/or libraries. The solution was:
1) Make sure Jdev is closed.
2) Rename the <jdev_home>\jdev\system9.0.5.1.1605 to something else (just in case).
3) Open JDev. Say no to any Migration questions.
4) Open your workspaces (jws files) using the File->Open dialog
I'm assuming, of course, that these projects are already JDev 10g Production projects. If they are not, then I think the procedure would be:
1) Install Jdev 10g Production
2) Run Jdev 10g Production. Say Yes and migrate settings and projects.
3) Follow the steps above to fix the migrated settings.
This should get your projects migrated to the new formats without contaminating them with old libraries/schemas.
I'll repost if I find something that breaks due to this procedure. I do know that it resolved my error messages.

Jdev 10g: property inspector bug

jdev 10g and ADF FACES EA15.
The property inspector is not showing the value of "valuePassThru" on af:selectOneRadio controls.

Hi Larry,
Thanks a lot for bringing to our notice. I will test it and report it to appropriate team, so that it gets fixed.

BUG: Jdev 10g/iAS 10g debug config docs are wrong

I was setting up my iAS 10g OC4J_Home for remote debugging. According to the docs in Jdev 10g, I have to copy ojc.jar and jdev-rt.jar to <OC4J_HOME>/home/lib. This does not work.
You must actually copy the files to <OC4J_HOME>/home/applib.
In my case, this is $ORACLE_HOME/j2ee/home/applib. If you create your own OC4J instance, then you must install these files into the applib directory within that instance.
Could someone please put out a definitive doc on how to get remote debugging to work between Jdev and iAS 10g? If it exists, please point me to it!
TIA

Hi,
what about the blank characters in the long name. If the long name doesn't have blank characters, would it work then ?

UIX table tag's attribute VALUE is missing in jdev 10g production

In JDeveloper 10g preview, I handled my table's navigation manually and need to set the table's tag attribute VALUE in order to keep the record range.
However, when i convert my project to JDeveloper 10g Production, eventhought the page is still working fine, but in the design windows will show that the uix page is in invalid state and I found that the attribute VALUE is no more supported.
Could anyone please help me and let me know how do i set back my record range? Thanks!

It turns out that you're running into a bug that will be fixed in the soon to be released version of JDev 10g. The good news is that it's a design time bug, so your pages will still work at runtime. You can even fix the bug yourself if you want. In JDEV_HOME\jlib there is uix2-schemas.zip. Inside of that is ui/table.xsd.
Add the below attribute definition inside of the complex type for the table, and you should be all set.
<attribute name="value" type="ui:unsignedIntExpressionType" default="1"/>
Hope this helps,

JDev 10G OSX Issues

Hi-
I am starting this thread as a discussion area for bugs and issues with JDev 10G on Apple OSX 10.3. JDev is not officially supported on OSX, however, I am hoping that by providing well defined issue lists we can move that process along. Please add to this list if you are running JDev on OSX and find other issues!
Thanks Gerard for encouraging me to post these (and sorry for my slow response).
Eric Everman
___Problems in the 10G release that were present in preview release___
-The Apple LnF has some missing icons and general painting issues in the file browser.
-com.apple.macos.useScreenMenuBar has been depreciated message on startup (noted other places)
-(MAJOR) JDev cannot correctly resolve paths using symbolic links. I haven't tried this, but I would suspect this is a problem on Linux as well. If I open a project that uses a symbolic link within its path, JDev seems to think there are two copies each file - one on the linked path and one on the fully resolved path. Somehow out of this, Jdev ends up placing all files into a Miscellaneous package under Web Content and Application Sources.
-Import... The dialog seems to have a hardcoded background color. When running under OSX with the Apple LnF, the background color is the dark color of the Oracle LnF in portions of the dialog.
-The sort order for files in the file dialogs is case sensative is a unfriendly way: A-Z sorts as a group before a-z. Preferable would be Aa, Bb, etc, as OSX applications (and windows applications) do. Is this also a problem in Linux?
-Quiting JDev results in the following error (terminal text from JDev start to JDev Quit):
================================
Exception in thread "Thread-0" java.lang.SecurityException
at oracle.ide.IdeCore$1.checkExit(IdeCore.java:165)
at java.lang.Runtime.exit(Runtime.java:88)
at java.lang.System.exit(System.java:715)
at com.apple.eawt.Application.handleQuit(Application.java:406)
JavaAWT: Assertion failure: Java exception thrown
JavaAWT: File src/macosx/native/apple/awt/util/AWTException.m; Line 40
JavaAWT: Assertion failure: _javaException
JavaAWT: File src/macosx/native/apple/awt/util/AWTException.m; Line 48
2004-04-30 10:54:36.344 java[2230] See Java exception object
================================
-Dual monitors Issue: (partially fixed) Works great under Apple LnF as long as com.apple.macos.useScreenMenuBar is 'false'. When set to 'true' and working in the non-main window (the window w/o the menubar), context menus pop-up at the edge of the main window instead of at the mouse location.
-Command-Q will quit JDev, but will not always kill the associated Embedded OC4J instance. I can't always reproduce this - perhaps it happens after I've switched projects, recompiled somethings, etc..
-Quiting JDev using any method other File|Quit results in the open file list not being saved. (Other methods are Command-Q or the JDev menu item Quit option)
___Problems in the preview release that were fixed in the 10G release___
-Fixed: The close/minimize buttons on tabs and panes now display properly in the Apple LnF.
-Fixed: Save As... removes the original file from the project list. So it looks as if the file has been renamed - in reality the original file is still on the disc, just no longer part of the project.
-Fixed: The state of open files is not restored when JDev is resarted. Somewhere along the line I ended up with the JDev Welcome page and a class file as being the open files each time I start JDev, regardless of what files were open when I closed JDev. Tried with OSX LnF and Oracle LnF.
-Fixed: When running under OSX LnF, editing code will result in the addition of a 'Code' menu to the menu bar, however, all of the other menu items are de-activated (greyed out). When the context changes to something other then code editing, the 'Code' menu item disappears, but all of the other menu items remain de-activated. Also, the Code item is added after the Help item, which is non standard. Under the Oracle LnF, the behaviour is as expected.
-(Have not replicated in 10G release) After switching from MS Windows to OSX using JDev 10G for both, leading square bracket characters ([) seem to be stripted from JavaScript in JSP pages. Additionally, an extra space is sometimes inserted after a litteral in square braces. If you see something similar, please submit more details. I have a more detailed writeup in the Technologies|Apple section - search for 'square bracket characters'.
-Fixed: Structure pane incorrectly displayed multi-line JSP comments that started with carriage returns.
___New Issues in the 10G release (or not before found)___
-On startup, several errors are listed in the JDev message pane:
================================
/Applications/jdev/jdev/lib/ext/bc4j_installer.jar!/META-INF/jdev-ext.xml
Error: <Line 4, Column 22>: XSD-2034: (Error) Element 'feature' not expected.
Error: <Line 24, Column 14>: XSD-2021: (Error) Element not completed: 'extensions'
/Applications/jdev/jdev/lib/ext/bigraphext.jar!/META-INF/jdev-ext.xml
Error: <Line 4, Column 22>: XSD-2034: (Error) Element 'feature' not expected.
Error: <Line 17, Column 14>: XSD-2021: (Error) Element not completed: 'extensions'
================================
After adding the JUnit extension, I also get these messages at startup:
=================================
/Applications/jdev/jdev/lib/ext/jdev905_JUnit Folder/bc4j_junit_addin.jar!/meta-inf/jdev-ext.xml
Error: <Line 4, Column 22>: XSD-2034: (Error) Element 'feature' not expected.
Error: <Line 39, Column 14>: XSD-2021: (Error) Element not completed: 'extensions'
/Applications/jdev/jdev/lib/ext/jdev905_JUnit Folder/junit_addin.jar!/meta-inf/jdev-ext.xml
Error: <Line 4, Column 22>: XSD-2034: (Error) Element 'feature' not expected.
Error: <Line 98, Column 14>: XSD-2021: (Error) Element not completed: 'extensions'
================================
-The window location and/or size is not restored on startup. I typically run dual monitors with jdev full-screen on the larger of the two. jdev often starts less then full screen size or not in the full screen location.
-Inner Classes are not properly used by JDev. This chunk of code:
================================
import java.util.Map;
//code in a method
Map.Entry entry;
================================
Results in JDev underlining Map.entry with a mouseover note that says 'Access not allowed for class 'java.util.Map.Entry'.
-Find and Replace with 'prompt' option locks the editor (hard to replicate)
-JDev will sometimes 'swallow' a keystroke while it is poping up a Code Insight box (hard to replicate)
___General Feature Requests___
-Several of the common File menu options could be added to the context menu in the Application Navigator tab. For instance, Save As, Remove From Project, Delete, and Refactor-> are all common functions that are nice to have 'right there'.
-When typing import statements, is there some way to have jdev continue showing context lists after a selection is made? For instance, when entering:
import org.apache.commons.lang.RandomStringUtils;
I type "org." which allows me to choose apache from the list. Then... nothing - I have to backspace to delete the '.' and retype it in order to get the next code completion popup. In JBuilder there was the option to select an item from the list by pressing the '.' (dot), which would immediately continue with another context selection box.

Okay, lets see how many of these we can already deal with:
** General Look And Feel Issues:
* Missing icons and redrawing issues in the file browser
Loged as new bug 3609752
* ...useScreenMenuBar has been depreciated message
Can find this, are you sure this is not being confused with the antialiasing messages?
* Dialog background colors
Logged as bug 2610818
* Open dialog sorting
Logged as new bug 3609768
* AWT exception on exiting:
Logged as bug 3525259
* Multi monitor bug
Unfortunately we only have a few macs and non of them have more than one monitor at the moment. But from your description this problem seem to lie with Apple rather than us. I will keep an eye on it for you though.
** Error messages on startup
I belive this is a common problem accross all platform.
** Inner classs issue
Again this is a problem with all versions of JDeveloper. Logged as bug 3546309, not currently scheduled to be fixed until the next release. Note that this only seems to affect the highligthing in the editor and nothing else.
** Items not being saved, position not being restored.
If you press Apple-Q the Java virtual machine will kill jdeveloper and not allow it to close down properly. This can be resolve by addin hooks provided by apple. For the 903 preview release we had an addin for this. I will look at providing a drop in for 9.0.5.1
** Symbolic links, and other enhancements
In will invetigate symbolic links and get back to you. I will also look at tracing down ER or log bugs for the other enhancemnts you mention
Thanks for the details,
G.

JDev 10g Developer's Guide....

Hi ,
Is there any Oracle e-book (free) guiding a developer to develop forms (of all types) in Jdev 10g (10.1.2. or 10.1.3)...???
many thanks,
Simon

Humm, thats kinda like walking into a car dealership and telling the salesperson "I want to buy a car"...
Fundamentally speaking, JDeveloper is just another IDE and there are many others like it, JBuilder, Eclipse, emacs (thats right I went there!) etc.. Its hard to distinguish these tools if you are just starting out on the arduous and humble path of software engineering. They can all more or less accommodate various n-tier technologies and allows you to build simple "hello world" examples to complex enterprise level applications. My advice is to pick first pick a technology then a simple project to start off. I'm not sure of your technical background, but speaking personally I got bit by the programming bug when I started using emacs to build a Swing based board game back in college, I didn’t read too many books, just lots of online tutorials (probably explains why all the code went into 2 or 3 files). Anyhow, I'm not sure if that was too helpful, but the point is you need to have a starting point, pick a couple of technologies first, then lets take it from there.

JDev 10g 'Code' menu

Could anyone enlighten me as to how to make the 'Code' drop down menu appear in JDev 10g.
I am running JDev 10g 9.0.5.0.0.1375 Preview and I had this menu at one stage but it seems to have disappeared. I've not knowingly chosen to hide it and can't seem to find an option to switch it back on. I am editing java source so would expect this menu to be active....
Re-installing JDev fixes this but this seems a little drastic. A bug possibly? Anyone any ideas??
Thanks
Steve

A less 'drastic' approach may be to exit JDev and:
(1) back up your system directory (i.e. %JDEV_INSTALL_DIR%\jdev\systemXXXXXXX to somewhere else
(2) delete it.
(3) restart JDev
I think this issue shouldn't appear with the production release due shortly.

JDev Mac OSX bugs in Apple forum

Hi-
Just wanted to let JDev people know that I've been posting several JDev10G Mac OSX bugs to the Technologies/Apple forum under the topic 'JDev 10G works on OSX!'.
I know: not officially supported betaware - but its there all the same. Generally JDev works quite nice under OSX as long as the Oracle LnF is used.
--Eric Everman

Thanks!
We have some people here running JDev on Mac OS/X as well. Glad to hear it's more or less working for you too.

URGENT - Migrating from 9i to 10g designer

Hi All,
I have installed new repository for Designer 10g (10.1.2.0.2) and
I have started Migration from Designer 9i (9.0.2.80.10).
I have error message from ckrau61 with cause:
"No Designer Repository has been detected.
Please check connection details and try again".
I have checked TNSNAMES.ORA and haven't found any error. Other
software works with old repository (9i) and i have checked the TNSNAMES.ORA on the server and not on the client ... Oracle is trying to build a db link and it is tested ok.
The Migration from 9i is not supported in 10g?
Help-me!!!!
Any tips would be helpful. Thanks.

You do not have to install a new Repository and "migrate" your data to upgrade from Designer 9i to Designer 10g. You just install the 10g Designer client, connect to your existing 9i Repository and "upgrade" it to 10g.
Please refer to the "Upgrading a Release 6i, 9i, or 10g Repository" section in the Repository Installation Guide for complete details.

JDev 10g and EJB 2.0 on non-OC4J server

It looks like JDev 10g only supports EJB 2.0 for OC4J out-of-the-box. Is this correct?
If we wanted to generate EJB 2.0 CMP entity beans etc to deploy to a non-OC4J app server (e.g. JBoss) using JDev 10g, what would we need to do? Are there any tutorials/how-to's available?
As a newbie to JDeveloper and J2EE, trying to work out how to re-write our Forms system in J2EE, I have to say I'm getting tired of how most of the JDev documentation - and much of the software - only seems to relate to using OC4J (or 9iAS) as your app server. If we and our customers wanted to be restricted an Oracle app server, we could just stick with Forms 9i and save ourselves a world of Java pain.
Plus, nearly all the 10g client documentation relates to JSP clients, but we want a rich GUI using Swing (JClient would be useful but we can't figure out how to deploy it 3-tier to JBoss).
So, Oracle, how about giving your users some more documentation on how to use JDev10g/JClient/ADF/EJB 2.0 etc with non-OC4J servers and perhaps even without JSP?
I am sure that JDev10g and ADF could offer us a great deal of help in building our system, if only we could figure out how to use it.
Thanks,
Chris

Thanks, Deepak.
But the how-to is for old versions of JDev/JBoss:
"This document was written for Oracle9i JDeveloper Release Candidate and JBoss 2.4.4 (Dated December 29, 2001), although other versions of Oracle9i JDeveloper and/or JBoss should behave the same."
I'll let you know if this works with JDev 10g and JBoss 3.2.3, but I have my doubts.
If anybody has some more recent information on this, please let me know!
Chris

JALOPY and JDev 10g 9.0.5.1

How can I incorporate jalogy in to Jdev 9.0.5.1?
I followed the instructions on jalopy website and it worked perfectly for Jdev 10g Preview but not 9.0.5.1. All I did before was just copy the jar files into <JDEV>\jdev\lib\ext directory and restart JDev. Now it doesn't work. Thank you in advance.

Thank you Rob for your fast response. However, it still doesn't work. However, I noticed that in the <JDEV9051>\jdev\lib\ext folder there is README.txt and it has some XML to define external plugins. I have not noticed it in the older release. Do I have to configure the plugins using XML config file now?
Again thank you in advance.

More info about Jdev 10g, where to get

Hi all,
I have done some jDev 10g tutorials for jsp, j2ee, struts. When i started to write some code on my one many problems appeared. So i am interested, where to get info, documentation or how to work with jdev 10g.
To get questions like :
-What is diferent between struts action and action data?
-How to develop with modules? If i'd like to have login, forum, calendar modules and use them in difrent application.
- ...what can be done with jdev 10g an also how
Any links or book titles would be fine or suggestions how to learn developing j2ee applications with jdev 10g.

BPA suite 11g and Jdev 10g

hello,
BPA11G is also compatible with JDEV10 ? I can use Jdev 10g with BPA suite 11g or not ? or we must install Jdev 11g ? (send a document about this)
BR,

Hi,
please install the JDeveloper 11g and apply the newest "BPA Extension for JDeveloper". Install the BPA Extension using the JDeveloper Update Center. From the JDeveloper menu choose Help > Check for Updates. Browse and pick the pcbpel_bundle.zip found in the Oracle BPA Suite 11g Addons.
It is necessary to keep the JDeveloper and BPA Suite version consistent, especially for the major releases 10 or 11. This is because in 11g a BPEL process is part of a SOA Composite, which means the technical concept has been changed as well.
Best regards,
Danilo
