I'm trying to develop a program using Oracle Forms that would allow me to check/insert data into my database. First thing I do is I open up XAAMP and start up Apache and MySQL. The second thing I do is I open up cmd, locate the oc4j.jar's directory and I open it using "java -jar oc4j.jar" command. After OC4J starts up without any errors, I go to the Oracle Forms Builder Edit->Preferences->Runtime and I change the apllication url to http://mycomputersname:8888/forms/frmservlet. After that, I click on the Run Form button. Internet Explorer starts up and for a 0.5 of a second, a text "ORACLE FORMS." appears on the screen. After that, the text Cannot found webpage appears on the screen. Oh yeah, I forgot to mention. I also successfully logged myself into my database before I tried to run the form.
Any help would be much appreciated. :)
I have fixed the problem. It appears that the issue was that I manually created an instance of oc4j.jar. When I instead clicked on Start -> Oracle Forms -> Start oc4j instance "Run Form" button worked just fine. :)

I'm using Eclipse (Kepler) for a GWT application and for some reason, superDevMode keeps appearing in my arguments. We are stuck with GWT 2.4 which does not know what superDevMode is. I remove the argument, hit Apply and Debug to start the app, but when I look at the arguments again, -superDevMode is in there again. I am assuming there is some property that belongs to 2.6 (the version that was installed with the Eclipse plugin), but I can't seem to find it.
Update: Below, Adam recommended that I go to the GWT tab and take it out of superdevmode. Here is a screenshot of that tab:
There isn't a way to do that. The large area at the top of the tab (above the Super Dev Mode group) suggested that something was supposed to be there, so I set the project's GWT to 2.6. Sure enough, there was a Super/Classic dev mode selection. I set it to classic, saved the settings, and then put the project back to 2.4. The GWT tab looked exactly as it does above and the arguments now has "-nosuperDevMode" in it, which is also not recognized by 2.4.
Any help would be appreciated.
Thanks,

I found a temporary workaround that comes with a caveat: I made the Eclipse Run Configuration file read-only.
Example path:
<YOUR_WORKSPACE>\.metadata\.plugins\org.eclipse.debug.core\.launches\<YOUR_RUN_CONFIG_NAME>.launch
Then whenever you bring up the Dev Mode Run Configuration in Eclipse it still shows the -superDevMode flag, but when you click the Close button it now asks you if you want to save and you can press No.
The big caveat: if you actually do want to change the Run Configuration Eclipse will ask if you want to save, you press Yes, the dialog closes, but it didn't actually save.
Easiest fix is to shutdown Eclipse, manually edit the .launch file to remove -superDevMode, make the file read-only, then start Eclipse again.
Here's the bug report.
Go to GWT tab (3rd from left) and switch from Super Development Mode to Classic Development Mode
I'm trying to upload a script, and the file is being uploaded fine, but in the Script Editor window where I'm going to actually run the script, the entire file content is shown on one line and the whole edit area is in red. I'm not being able to run that script. Also if I create a new script from the editor, the edit area is again in red and I'm not able to save it. Please help me understand what's to be done so that I can run my SQL scripts.
Ok, so I figured it out by myself. So I'm answering my question so that it may help anyone else who have had this weird problem. When you open the database home page on any browser other than IE, this problem occurs, and you won't be able to do a single thing with your script. So always open your database home page on IE if you have to upload some data. For all other tasks, any other browser is fine. Cheers.
When I try to run a Servlet by using "Run on Server" eclipse asks me "do you want to save this file or find a program online to open it

there is no problem with the code. please help me, am unable to figure out...
same problem was faced by another guy...

still problem is unanswered...
You misspelled your content type.
Since the browser doesn't know how to display test/html, it offers to save it instead.
Your
res.setContentType("test/html");
will be
res.setContentType("text/html");
Note that "test" was changed to "text".
I am developing in PHP with Xdebug and for some reason every now and then the debug session stops working, so i click again the debug button but it gives me this error all the time "Web launch already running", so i have to go to Debug Perspective and click "Terminate and Relaunch".
Is there a way to make eclipse automatically terminate and relaunch or launch two sessions or don't show this popup, for 2 years this popup has been bugging me xD
As noted in response to questions like this one and this one, the best current solution appears to be binding "Terminate and Relaunch" to a keyboard shortcut.
Not automatic, but at least a lot less clicking around.
I have taken care of pesky popups in Eclipse with AutoHotkey script which have worked very well. I could create an AutoHotkey script which sends specific keystrokes automatically every time there is a specific pop-up.
So the flow I had in mind was as follows :
You click on the debug button -> The Error popup appears and as soon as that happens the AutoHotKey script kicks in and automatically does what you have to do manually.
If you think that might be worth looking into then we can talk more in a Chat session somewhere. I would need some information about the Pop up using the AU3_Spy.exe bundled with the AutoHotkey Installer.
Searching on Google, I found that many people have the same problem.
Bellow are some links that help you, I think:

A good article: http://www.latenightpc.com/blog/archives/2008/05/24/a-complete-lamp-development-environment-xampp-eclipse-pdt-and-xdebug

So, read and try, read and try.
I'm banging my head against the wall trying to figure this out.
I'm using NetBeans 6.9.1 and I have a project of type "Java Application." This project contains no Main method, but instead a Japplet named AlarmClock.java. When I right-click and run AlarmClock.java, it runs correctly with no problems. What I can't figure out is how to get this applet to run on a website (or even locally on my computer for that matter). I've tried building it and opening up ProjectDirectory/dist/launch.html which starts up launch.JNLP which opens up a webpage with a space for my applet, but this space just contains an error message.
I'm not sure if it's something wrong with my project settings, and I don't know what a "codebase" is or whether "Web Start" should be on. Do I need a main method that opens up my applet, and how would I do that? Some advice would be hugely appreciated.
That is a typical situation where a full IDE is too much. To understand the background is better to take a simple text editor and let you guide by a Java Applet Tutorial.
Once you feel good with applets make the same exercise with your preferred IDE. If not you have to learn Applets + "How my IDE handles Applets" at the same time.
