The Danish RED plugin is a third party tool. You should contact the author.
The only reference I found is the diploma thesis of Machiej Kucharek, done at the Technical University of Denmark (www.imm.dtu.dk).

Cannot update software in Eclipse Kepler
Hi,
I am trying to update the software within the eclipse Kepler for SAP plug-ins. However, I encountered an error message saying that repository is not found. Could any expert help me resolve this issue? The error message is attached for reference.No need to uninstall, just run the installer to replace the current system folders.
If that doesn't work and you need to erase and install, come back here and we'll give instructions or point you to where you can find them.
Likelihood is though that you only need to run the install disc 2 to restore your iLife applications.
If your profile is correct (10.6.4) you won't have the app store; it wasn't introduced until 10.6.6.
If you want it, the last update for Snow Leopard is 10.6.8 (this includes additional security features) which you can download from http://support.apple.com/kb/DL1399 -

}Ok, given that I may have not been the kindest to you on the other thread (and I'm still annoyed that you went and cross-posted this), and that you did actually use code tags, I'm going to post some code here:
Please take the following advice onboard though.
1. When you are naming your artifacts, please use the java coding standard as your guide. So if you are naming a class you use a capital letter first, and use camel case thereafter. All method names begin with a lower case letter, and all variable names begin with a lower case letter (and again camel case after that)
2. Please use self explanitory names (for everything), so no more row1, row2, or text1, text2, etc.
3. The example I am giving below makes use of a single class to handle all actions, this is not really the best way to do this, and a better way would be to have a class to handle each action (that would remove the massive if() else if() in the action handler class.
4. When you are using class variables they should be private (no exceptions, ever!), if you need to access them from other classes use accessors (eclipse and other IDE tools can generate these methods for you in seconds)
5. Notice the naming convention for my constants (final statics), they are all upper case (again from the java coding standards document, which you are going to look for with google right?)
6. I have hived some of the creation work to helper methods (the getSubjectTextField() etc), although it isn't advisable to be calling other methods from the constructor, since this is a GUI, and you want it to appear as soon as you create the class, we won't worry about this, but perhaps as an execrise you could work out a better way to do this?
7. Personally, I don't like classes that implement listeners, unless they are specifically designed to do that job. So a Frame that is set up as an action listener is fine, provided the actions it listens for are associated with the frame, not its contents. If the actions are related to its contents, then a dedicated class is better.
8. Another personal opinion, but I feel it makes code clearer, but others may disagree. If you are creating a variable solely to hold the result of a calculation, to be passed to a method in the very next line, then don't create the variable, just pass the method as the argument to the method (feel free to ignore this advice if the method call is extremely long, and a local would make it easier to read)
Anyway, here is the code. I have removed most of the menu items, and leave this as an exercise for you. Also I have only created 2 methods (new and exit), I'll again leave it as an exercise for you to complete this.

Need help with almost completed plugin engine project
Hi all,
For a while now I have been working on a plugin engine. After a few iterations, the engine is similar to the Eclipse engine, in that plugins use extension points and extensions to allow contributions. Unlike the eclipse engine I have added the ability for plugins to fire events through the engine and other plugins can add listeners, all through the plugin.xml manifest. Dependencies are mostly handled automatically at plugin load time (when extensions get resolved to extension points, and listeners get resolved to events). For the case where a plugin needs to use classes from another plugin, dependencies are also allowed to be declared. Like the eclipse engine, activation of plugins occurs the first time a class is used within the plugin's classpath, OR a plugin can be activated after it is loaded.
What I need help with is testing, working on examples to provide with the engine project, and feedback/suggestions before we release the M1 build. I am asking for those that are interested in this type of work to volunteer to help where applicable and possible. I want to provide a solid plugin engine to the java community, one that is easy to use, works well, and is pretty effecient in terms of resource usage and performance.
Of particular interest to me right at the moment is dealing with multiple versions. As I see it, the engine will be used within an application and as such plugins would be distributed with a specific application version. The plugin version itself is more of a notification as to what version a plugin is, although I imagine it will help when updating at runtime as well.
Just a few other details of the engine. It handles (or will soon) dynamic load, unload and reload of plugins at runtime. Plugins can be distributed in an archive file format, we call .par (Plugin ARchive), with additional plugin filename extensions configurable at runtime. The plugins can be developed and deployed in an expanded directory format as they are in Eclipse as well, or in the archive format. In the archive format they do not need to be unzipped when deployed, and they can contain embeded jar/zip libraries. The engine handles finding and creating classes directly out of the .par file at runtime.
Multiple locations to find plugins are configurable before the engine starts, and even after it starts more could be added to allow additional locations to find plugins. URLs are supported, and soon the HTTP protocol will be supported so that plugins can be downloaded and installed at runtime.
The project can be found at www.sourceforge.net/projects/genpluginengine. If you would like to get involved and help out, please sign up on the dev mail list and send an email to introduce yourself to the rest of the members on the list.
I'll also add that I am working on a Swing UI Framework built entirely from plugins. It provides a ready-to-launce UI application that developers can simply add their plugins to, extending various extension points of the framework to have menu items, toolbar buttons, status bar access, help and preferences dialog additions, file i/o choosers, tons of open-source components ready to use (or extend to add on to), and like Eclipse, hopefully... draggable window frames that can be dropped on any other frame to form a tabbed frame of windows. Some of this is a ways off, some is getting there now. Presently you can add menu items that do allow plugin activation when first clicked, so plugins can be loaded but not activated until needed. The Preference dialog works but is not completed, and a plugin that adds a plugin control panel to view all loaded plugins, activate them, load/unload/reload, view extension points, extensions, dependencies, etc is partially completed. The point is, to allow a ready to run UI framework in Swing with an easy path for developers to quickly build applications with. If you are interested in this, when you join the mail list and introduce yourself, indicate that you are interested in this as well, as we need help with plugin development for it and would appreciate more help here too.
Look forward to some replies.Might I suggest setting up a project at a known project-site? I've seen your progress and questions posted here from time to time, but one of the drawbacks is that you have to fill each post with the entirity of your vision to explain what you're doing. That's a lot of text to read - and most folks will skip right over it.
On the other hand, a well-crafted, good-looking project web-site, with appropriate links and docs and vision statements, diagrams, etc. will have more likelyhood of attracting volunteers. java.net and sourceforge.net are likely spots to set up shop. In addition, you get CVS and bug-tracking systems, which can be quite valuable in such a large-scale project where there are lots of pieces. -
Help with eclipse installation, please!
I usually use dreamweaver but now I have to use eclipse. I'm
so confuse as where to start. I've googled for guide to eclipse
installation but not sure what to do.
Here is what I found:
On this link
http://www.cs.umd.edu/class/spring2006/cmsc132/EclipseTutorial/install.html
it says I have to first install jdk-1_5_0_04-windows-i586-p.exe but
I can't download this file because I'm not their student. I looked
around everywhere and can't find this file for download.
Then I thought I may be just download eclipse from
http://www.eclipse.org/downloads/
When I clicked download, I'm face with anothe confusing page,
I'm not sure which one to choose.
Do I have to download : Eclipse Classic 3.4.1 (151 MB) ? how
about JDK?
I searched for JDK on my machine and I did not see any jdk
except jdk12utils folder, jdk118 folder, jdk122 folder and jaguar
server (jdk1.2). There a re a bunch of other jdk such as JDK_JJ,
JDK_VJ, etc
I need to use eclipse just to develop web application with
coldfusion (locally) and databse Sybase and that is it. No java no
nothing and I'm no java person so these things confuse me, please
help!
Oh by the way, I also read somewhere that once I installed
eclipse I need to install the CFEclipse.
Please help!!!!>

Really? I just Googled "jdk-1_5_0_04-windows-i586-p.exe" and
found rather
a lot of matches. One can download it from the very first
link.
There are more recent versions of Java than that, though.
If you ever need to download a JDK, the Java website is
perhaps the best
bet (java.sun.com).

OK, some background. Eclipse is a Java application, so to run
it, one
needs Java installed.
If you don't already have a JDK installed, then the option
you want is the
one WITH the JDK, because that will definitely be the a
suitbale version to
run Eclipse one. One might not want to D/L the version
bundled with a JDK
if one already has the same or more recent JDK installed.

Well: start by googling CFEclipse. On the website for it,
there'll be a
D/L as well as instructions. It's pretty straight fwd, if one
reads the
instructions.

I need help with reporting as soon as possible!
How can I do reporting in JDeveloper like in Crystal reports. Is there any extention or tool that can be of help.
Thanks
Edited by: Fenoch on Mar 12, 2010 6:34 AM
Edited by: Fenoch on Mar 12, 2010 6:36 AM@Fenoch,
I'm also new to the JDeveloper world and I haven't gotten into reporting yet, but a couple I've heard about are
Oracle BI Publisher - http://www.oracle.com/technology/products/xml-publisher/index.html
Jasper Reports - http://www.jaspersoft.com/
BIRT - http://www.eclipse.org/birt/phoenix/ (more of an eclipse thing I think)
I hope that helps, I'd like to hear what you find out about any of these.
Don't let elitist responses run you out of the community.
@John,

JDeveloper doesn't have reporting capability, per se, but there are a number of Java-based reporting tools out there, which you could find [url http://www.lmgtfy.com/?q=java+reports]here
John
Way to be an ass to a newbie. It is posts like this (from an Oracle "Ace" Director no less) that push people away from the platform.
Maybe you could post a link to a reporting tool you know about, instead of sounding off like an elitists jerk and belittling a new guy. I'm sure you popped into the world full of knowledge and ego, never received any help or asked any "newb" questions.
I also find it very interesting that your "helpful" search link sends us to GOOGLE and not on a search of these forums. Could it be that the forum search is unreliable and returns garbage results most of the time?
You could have linked a forum search -
http://forums.oracle.com/forums/search.jspa?objID=f83&q=java+reports (Typical unhelpful results set)
http://forums.oracle.com/forums/search.jspa?objID=f83&q=reports (Slightly better, at least has a couple posts talking about Jasper)
Re: Report Facility
Or if you just gotta use google at least narrow it to the forum you are suggesting we search in -
http://www.google.com/search?hl=en&as_q=java+reports&as_epq=&as_oq=&as_eq=&num=100&lr=&as_filetype=&ft=i&as_sitesearch=http%3A%2F%2Fforums.oracle.com%2Fforums%2Fforum.jspa%3FforumID%3D83&as_qdr=all&as_rights=&as_occt=any&cr=&as_nlo=&as_nhi=&safe=images
It is actually the low quality of the forum search tool that forces people to re-post the same questions as others have. I know I do it all the time after I've attempted multiple searches.
TL;DR version
Be helpful or be silent.
Bullying the new people pushes them away and hurts the community. No new people -> no more JDeveloper. -

I'm a new OEPE user, and found that after installing it, Eclipse (Kepler) now starts up with the wrong workspace every time. I have to explicitly do File > Switch Workspace... to get Eclipse to restart with the correct workspace. Also, the workspace I want to use is the only one listed in the Workspaces preferences panel (Window > Preferences > General > Startup and Shutdown > Workspaces). So I can't figure out why Eclipse is using the wrong workspace, and why it's even finding this wrong one.
I found that many other users of OEPE with Kepler are having this same problem:
Eclipse Community Forums: Eclipse Platform &raquo; Kepler: On start up, I no longer get prompted for workspace locat…
And this sounds curiously like this old problem reported right here on the OTN Community site:
https://forums.oracle.com/thread/2191740
Any suggestions for how to get around this? I assume this is a bug, but don't know the correct process for reporting OEPE bugs.77e559c0-cd28-48cd-916f-3f755e9683b5 wrote:
Hi.
I suspect that some action by the OEPE code somehow modifies the OSGi Cache so that it no longer asks you what workspace you'd like to use (and forces usage of the workspace in top user directory.) I found that if you put in "-clean" in your eclipse.ini, then you get asked what workspace you'd like to use. This flag clears out the OSGi cache (hence my theory that it is this cache that is messed up)
That said, there are arguments for not doing this all the time. See this discussion: java - How to run eclipse in clean mode? and what happens if we do so? - Stack Overflow
Finally, I suspect you have another workspace on your system now. Presuming you are on a PC, go to your user dir - I'd wager there is a "workspace" dir there now. That is where OEPE wants to work.
Good Luck!
OEPE should be able to work with any workspace; it has in the past! If a specific workspace is required with this release, that is a step backward in my opinion. That said, if that is the direction of the product, so be it. I find it hard to believe that is the direction of the product, however! -
Need help to develop Pythagoras theorem-
Hi i need help to develop proofs 2,3,4
of pythagoras theorems in java as demonstrations
These are applets can anyone help me with it or give me an idea of how to go about developing it -
the site is the following
http://www.uni-koeln.de/ew-fak/Mathe/Projekte/VisuPro/pythagoras/pythagoras.html
then double click on the screen to make it startPardon my ASCII art, but I've always liked the following, simple, geometric proof:
a b
---------------------------------------+
| | |
a| I | II |
| | |
---------------------------------------+
| | |
| | |
| | |
| | |
| | |
b| IV | III |
| | |
| | |
| | |
| | |
| | |
| | |
---------------------------------------+It almost goes without saying that I+II+III+IV == (a+b)^2, and II == IV == a*b,
I == a*a and III == b*b, showing that (a+b)^2 == a^2+a*b+a*b+b^2.
I hope the following sketch makes sense, stand back, ASCII art alert again: a b
---------------------------------------+
| . VI |
| . . |a
| V . |
| +
| |
| . |
b| . |
| |
| IX |
| . |
| . |b
| |
+ |
| . |
a| . . VII |
| VIII . |
---------------------------------------+
a bThe total area equals (a+b)^2 again and equals the sum of the smaller areas:
(a+b)^2 == V+VI+VII+VIII+IX. Let area IX be c^2 for whatever c may be.
V+VII == VI+VIII == a*b, so a^2+b^2+2*ab= c^2+2*a*b; IOW a^2+b^2 == c^2
Given this fundamental result, the others can easily be derived from this one,
or did I answer a question you didn't ask?
kind regards,

Please help me on what to do.
ThanksAudio and video are not currently support on Adobe Reader. :-<
You need to buy a PDF reader that supports them. My suggestion is PDF Expert from Readdle ($US 9.99) -
