I have created a swing program that displays a gui and takes user data from the respective gui. The program works fine when I am running it from eclipse. But the problem is that when I make an executable jar file and double click it nothing happens. Even if I run the jar file from console nothing happens and exception occurs. I am using scheduler and for that I am using a quartz.jar file. I guess the problem is not there.
The exceptions are shown below...

I have added the main class in manifest.mf file, but no success.
Can anybody help me?
Here you go: File -> Export -> Java - JAR file, on the next screen check "Export java source files and resources"
or
read this link for command line executable jar conversion
http://www.mkyong.com/java/how-to-make-an-executable-jar-file/
or
if u want to convert windows exe use this tool Launch4J [http://sourceforge.net/projects/launch4j/]
Check your manifest.mf
after
Main-Class: YourClassHere
should be end with a new line or carriage return
Warning: The text file must end with a new line or carriage return. The last line will not be parsed properly if it does not end with a new line or carriage return.

I'm trying to use Change Assistant to apply a patching from tools 8.51 to 8.51.19 (yes I know that's ancient). I installed PeopleTools 8.51 and then installed PeopleTools 8.51.19 over the top of it. Then I installed Change Assistant and configured it to Perform PeopleTools Only Upgrade in the Tools > Options menu. Then I went to File > Import Template to import my upgrade template. Then I went to File > New Environment and created my environment (the test connection succeeded). But when I go to File > New Job and select my template and environment and Type of Upgrade = Initial Upgrade, I get this error

I don't have an older version of Change Assistant available to look at, but I think you want to actually "Apply a PeopleTools Patch" if going from 8.51.xx to 8.51.19. I don't recall if that is called out separately in the older CA versions, but those are two different options in the latest versions and I think has been like that for a while. The "Perform PeopleTools Only Upgrade", or "Upgrade PeopleTools", would usually mean going from something like 8.51 to 8.55.
I have a JavaFX Text whose textProperty is bound to a String in a separate thread that represents a time for a countdown timer that is throwing an error. It never throws this error when the textProperty is only changed once per second but when it starts updating every 1/100 second it will work for a few seconds and then I get this error:

I came across this topic, JavaFX append text to TextArea throws Exception, which seems to have a similar problem. Is it because I am updating the Text too often and if so is there a better way do this? Thanks

Can any one please help me on this?
Thanks in advance.
It would seem that the Netezza JDBC driver is not in the classpath for this application. You need to place the nzjdbc.jar file in the lib subdirectory of your application, or in some other location that is also in the classpath.
You'll have to add the nzjdbc.jar to the lib subdirectory yourself. As this is not open source it cannot be included in the dbfit distribution.

Why it happen, please help... Thanks
at line No 2407 in source code:
StandardJavaFileManager fileManager = compiler.getStandardFileManager(c,
Locale.ENGLISH,
null);
The only possible place for a NullPointerException is this line:
StandardJavaFileManager fileManager = compiler.getStandardFileManager(c,
where the compiler is null. You should add println(System.getPropert("java.home")) statement to see which JRE/JDK is running the application.
My guess is that your JAVA_HOME is pointing to JDK and is in the PATH, but Windows is using JRE, as per ".jar" file association.
UPDATE:
You can run it with a runapp.bat file like this one:
%JAVA_HOME%\javaw.exe -Xmx1024m -jar JavaEdit.jar
The BAT file must be in the same folder as your JAR file.
UPDATE2:
Make sure you have defined the JAVA_HOME environment variable. You check with this command:
c:\> echo %JAVA_HOME%
It should print out the location of your JDK - C:\Program Files(x86)....
If you're getting a null JavaCompiler (or an NPE getting it), then I'm guessing you run your application with a JRE and not a JDK.
From the JavaDoc
Returns: the compiler provided with this platform or null if no compiler is provided

Appreciate your help.
It looks like your client is sending a session ID that doesn't exist on the grid. Did the session timeout? Take a look at the grid console to see what it thinks is executing.
