Problem running stanalone applications created to NetBeans 3.6!!

Hello everybody.I am using NetBeans 3.6 with j2sdk1.4.2_05.
I have implemented a jframe application and I would like to run it as a standalone application.
As far as I know there are two ways to run a jframe as a standalone application.
As a .bat file, inluded the "java <jframe name>" or via the Java Web Start.
Actually, is any other way?
When I try to run it from the command line I simple type:
c:> java <jframe name >
and it returns me the message:
jframe.java:86: package org.netbeans.lib.awtextra does not exist
getContentPane().add(txtf_statusbar, new org.netbeans.lib.awtextra.Absol
uteConstraints(0, 210, 310, 20));
Do I have to include the org.netbeans.lib.awtextra package in my classpath?
How can I do that?
Thank you. I really appreciate any help.

Thank you.But...
The awtextra folder of NetBeans is located in "C:\Program Files\NetBeans3.6\sources\org\netbeans\lib". I included this in the Path envirnoment variable. The jframe is my a JFame applications(standalone hopefully).The jframe is located in j2sdk1.4.2_05\MyProjects\jframe.
I also typed from the command line the following:
c:\j2sdk1.4.2_05\MyProjects\jframe> javac -classpath . Program Files\NetBeans3.6\sources\org\netbeans\lib\awtextra jframe.java
and
c:\j2sdk1.4.2_05\MyProjects\jframe> java -classpath .Program Files.NetBeans3.6.sources.org.netbeans.lib.awtextra jframe
The same problem again.Cannot find package ord.netbeans.lib.awtextra
Where is the wrong?

What error indications do you get? You have to enable error logging in the Java Control Panel to see the details.

Problem running javafx application in web browser

The application runs fine when i build it in netbeans and run it. but when i try running it in a web browser, it displays a blank square!
the following is the html page that netbeans generated:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>tasklistinbrowser</title>
</head>

</script>
</body>
</html>does anyone know where i'm going wrong?

I also have a problem when trying to run my application in a browser. (running with netbeans works)
Only a grey shape appears.
But it seems to be a problem with the application itself, because other applications can be run in my browser without any problems.
any ideas? thanks

Having problem running an application

I have recently installed jdk 1.2.2 and i have no problem running applet but when i try to run an application i get the message 1 error can't find<filename> . java.
The path in autoexec.bat is fine. JRE File is include in my file jdk1.2.2.
I have installed and deinstalled it a couple of time and can't make it work.
Could someone help me please!!
Thanking you in advance!

doesn't sound like a path problem at all. you say when you try to RUN the app you get a message can't find filename.java. When you're running the app you run the binary class file i.e. java MainClass.class. If you're compiling the app you would do javac MainClass.java. Clarify your situation further if this does not help you out.

Error with running JAR files created with NetBeans

I have been having difficulty running the JAR files that NetBeans compiles. When I run my code from NetBeans, it always works just fine, but when I try to run the compiled JAR I get the following errors:
Exception in thread "main" java.lang.UnsupportedClassVersionError: Bad version number in .class file

This is happening for multiple projects now, though I don't remember it happening before. What am I doing wrong? Why is this happening? How can I fix it? Thank you for any insights...

Oh, I forgot to mention, all the NetBeans samples work, just not apps that I create. This is very frustrating!

Problem running Sample Application after intalling patch set 4.0.2.00.07

We just applied the patch set 4.0.2.00.07 on our TEST environment APEX4.0.
Now I can't run the sample application. When I run the application, login using either the admin or the demo user with the #lower_case_workspace_name#", the browser is generating below error message:
ORA-06550: line 2, column 8: PLS-00201: identifier 'CUSTOM_AUTH' must be declared ORA-06550: line 2, column 1: PL/SQL: Statement ignored
Error ERR-10460 Unable to run authentication credential check function.
The sample application works fine on our DEV environment APEX 4.0.0.00.46 *without* the patch set 4.0.2.00.07.
Does anyone have an idea how to resolve this
Thanks

Varad -
I see that these functions are missing on the TEST environment parsing schema. I will have our DBA rectify the issue.
Thanks,

Is there a problem running Java applications on my mac?

I am trying to set up a new website, and am therefore trying to upload photos. I get a warning message saying:
"this application will run with unrestricted access which may put your computer and personal information at risk. Run this application only if you trust the location and publisher above." and
"This application will be blocked in a future Java security update because the JAR file manifest does not contain the Permissions attribute. Please contact the Publisher for more information"
Does anyone have any advice for me?

There is no official iBook app for the Mac, but there are plenty of applications for reading a variety of ebook formats as above. Another is Calibre, which can read the ePub format that is used for iBooks. The software is free, take a look here:

Problems running Java Application. Prease Help Me!!

I've just finished a java application to my University, I used Forte for Java and the Timer that comes with it, it works fine, but, when I try to run it from outside Forte, it's just impossible, I even create a .jar file(with Forte 4), but when I try to run it from Forte, it tells me this:
java.lang.NoClassDefFoundError: org/netbeans/examples/lib/timerbean/TimerListener
Exception in thread "main"
it seems that it's a problem with the Timer, why??
And when I try to run it from the explorer (Windows), by double clicking the file, it tells me:
Java Virtual Machine Launcher
Could not find the main class. Program will exit!
But how is that possible??, it works fine with Forte. That's my problem, I need to take it to the teacher, but I can only run it from Forte now. What can I do??? Any suggestions?. I Hope that somebody can help me, please.

This sounds like a problem with the classpath. I was facing similar error with another application. Finally I ended up unzipping the class files and putting them in a directory that was in my class path.
Or you could explicitly specily your classpath.
Say your application (called app) is in c:\java\app and your classes are located in c:\java\classes\ where classes is directory run it like:
c:\java>java -cp c:\java\classes[;second path] app
hopefully it works.

Hi Recco,
I hope I'm wrong , I think XP is not supported for AS.
The second thing is U have not enough memory to run AS, that why U will always get problem with Java.
The third thing is about your Env. I mis jre path
ex. at your user profile & system profile just put for example
ORACLE_HOMe just give your oracle software home
by PATH U need to say for example c:\oracle_HOME/jre/1.4.2/bin
Hear from U,
Regards,
Hamdy

Any problems running Windows 7-created help output on Windows XP machines?

Hi,
I feel a bit silly even asking this, but I'm not a coder and don't have the technical knowledge to know for sure that it's a silly question.
Background: We are upgrading to Windows 7 from XP in the near future. We will be using RoboHelp 10 and Word 2010 - at least that's the plan ...
For our department's major product, since it's big and has been around a long time, we are still stuck using RoboHelp for Word to generate WinHelp. We then use the RHelp for Word source to generate WebHelp, since some modules of the product require WinHelp, some require HTML pages, and much of the source material is needed in both outputs. And yes, I did read someone's post likening this process to drinking coffee while running a sprint - believe me, if I had any choice about this I wouldn't be doing it. If RoboHelp has added the capability to generate WinHelp from RoboHelp HTML, let me know .
Anyway, because of previous weird experiences after upgrades, I am being asked to find out: Has anyone used RoboHelp for Word to generate help output - .hlp or .chm or HTML pages - on a Windows 7 machine and tested it on a Windows XP machine? If so, were any problems observed?
Assuming we can still creak along with RoboHelp 10 to generate the same antiquated output ... which we can, right?? ... my gut tells me that a file is a file and I can't see why an .hlp file or web-based help files that run on Windows 7 wouldn't run on XP. But again, I don't have the technical knowledge to say this for certain.
Any advice appreciated. Thank you - Sandy
Message was edited by: sdryer

Creating an output on a later OS does not affect its ability to be used an older OS. The issue, as you know, is creating winhelp to be used on Windows 7 or 8. That forces each user to download a file to support winhelp.

Problem running JavaFX application as web applet / web start

Hi All,
I need to run a JavaFX application as applet in a web page. To do that I use the html page
generated by javafxpackager and all works fine if I launch the html page locally from my
pc but when I load the html page from web server the application runs slow till freezing the browser.
All jars are signed with a self-signed certificate, I've tried with Firefox, Chrome, IE and different servers.
Same problem with web start (jnlp), locally works fine, launched from web it freezes.

Some more info,
I watched the web server logs and I found many repeated log entries like
"GET /applet/myapplet.html/META-INF/services/javax.xml.stream.XMLInputFactory HTTP/1.1" 404 19023 "-" "Mozilla/4.0 (Windows 7 6.1) Java/1.7.0_09"
Googling this I've found many posts regarding similar problems:
http://stackoverflow.com/questions/7997566/web-service-client-applet-keeps-asking-for-meta-inf-services-javax-xml-ws-sp
http://stackoverflow.com/questions/2340969/applet-served-by-java-web-start-resources-requested-to-web-server-before-look-i
It seems to be a strange Behaviour of the JNLPClassLoader that tries to load classes from server instead from jar or local class path.
Somebody suggests to remove all logging entries from code or to add "codebase_lookup = false" to applet parameters but this does not solve the problem.
I use FXML to define my UI and I think that every time an fxml is loaded JNLPClassLoader tries to load the xml parser (javax.xml.stream.XMLInputFactory)
from server.
Somebody have any idea?
Thank you.

Problems running Air Applications

3 days ago, I was running inCombat 4e perfectly fine, without any issues.
Yesterday, I installed this app, it worked fine for a while. I closed it down and went to start it up later. That's when the problems started. I get the license agreement screen(pic), and when I click "I Agree", that screen closes and nothing happens. At all.
I uninstalled Air and the 2 apps I use, restarted and tried to reinstall, but I get the same issue. I'm running Windows 7, Pentium Dual Core 2.2 GHz laptop with 3 GB RAM.
Here is my install log file as well. Any help is greatly appreciated.

[email protected] have an identical problem. I run Times Reader and IHT Reader on AIR. After the update, when I launch the application, I get the license screen and when I click on agree nothing happens. I uninstalled AIR and the applications and reinstalled them. The problem remains the same.

Problems about creating an application client using Netbeans 5.0

Dear all,
I have created an "enterprise application" project in Netbeans 5.0 and I want to create an AppClient to access the EJBs in the project. Since Netbeans 5.0 did not contain automatic support for AppClients. I need to do some configurations to make it act like an AppClient. (I am forced to use version 5.0 but not 5.5)
After searching in google, I found the following article about creating an AppClient in Netbeans:
http://www.netbeans.org/kb/41/app-clients.html
I read through the steps in this web page and carefully apply it to my own enterprise application. Everything was fine but when I cleaned and built it, Netbeans told me there's something wrong in the build.xml of my AppClient project:
init:

This is the build.xml file of MyAppClient project:

Could somebody tell me how this error can be fixed or at least give me some clues what is the possible cause of this error?

I have forwarded this to another team member. Stay tuned for the response.

Netbeans is unable to deal with alias host name "localhost". But it isn't the only local server.
Search for *::1 localhost* in your host file.
I have Windows OS so host file is in this folder
C:\Windows\System32\drivers\etc\hosts
add *127.0.0.1 localhost* to the hosts file above the existing entry
Should look like this:
127.0.0.1 localhost
::1 localhost
Stop server and close netbeans (if not already done).
Restart and test. Server startup should be quicker.

I'm having problems with JavaFX applications run on raspberry pi!

I'm having problems with JavaFX applications run on raspberry pi. I did all the steps of the videos of the course: overclocking, uncommented what I had to uncomment about the framebuffer but Exceptions are still happening. The Fireworks demo example does not work. Someone went through this problem? Java applications are ok. As the versions of java in netbeans project and also on "properties" and they are all JDK 8. So if someone can give a hint, I'm very grateful!

Can you provide the exceptions you got so I can help you better?
Would you like to do a coaching session for this?
