Error in JBuilder 2005 application

[Elsie]

I developed an application in JBuilder2005 and I create the .jar file. But when I try to run it from the command line, I get the following error message:

Exception in thread "main" java.util.zip.ZipException: The file is not found
at java.util.zip.ZipFile.open (Native Method)
at java.util.zip.ZipFile.<init> (ZipFile.java: 112)
at java.util.jar.JarFiles.<init> (JarFile.java: 127)
at java.util.jar.JarFiles.<init> (JarFile.java: 65)

I even tried to double click the .Jar file but that doesn't work either. I reinstalled the JBuilder2005 but the problem remains the same.

How are you running your jar from the command line?

Also usually when there is an exception, the StackTrace will also tell you where is your error. e.g which line number generates that error.

[Elsie]

java -jar name_application. jar

this is how I ran the jar file.

For the line that generates the error, everything is mentioned in the first post. I think you missed that part.

at java.util.zip.ZipFile.<init> (ZipFile.java: 112)
at java.util.jar.JarFiles.<init> (JarFile.java: 127)
at java.util.jar.JarFiles.<init> (JarFile.java: 65)

at java.util.zip.ZipFile.<init> (ZipFile.java: 112)
at java.util.jar.JarFiles.<init> (JarFile.java: 127)
at java.util.jar.JarFiles.<init> (JarFile.java: 65)

This certainly occurs if you are calling things that do not exists. As per your code, at the 112 line you might have called for a zip file which either doesn't exists or the location of the file is wrong. The same goes with the jar file in line 127 and 65. Just provide the proper location and that's it. You are done.
