在Windows上创建的jar在Linux上不起作用

Question

I exported a runnable jar from Eclipse on windows 8.1. When I try t tun it on kali linux it gives 'Invalid or corrupt jarfile'

I then created the jar using intellij, but it give the same error on kali linux.

Jar works fine on my windows system created by either method. I am using oracle jdk 6 to export the jar. On kali linux I have openjdk installed.

Oupout of unzip DocUploder.jar on kali linux

Archive:  DocUploder.jar
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
note:  DocUploder.jar may be a plain executable, not an archive
unzip:  cannot find zipfile directory in one of DocUploder.jar or
        DocUploder.jar.zip, and cannot find DocUploder.jar.ZIP, period.

Answer 1

Well, since the answer is obvious after the long chat I'd provide the action list that helps to find problem like "my jar does not run".

1. Check the command line. Be sure the classpath is correct.
2. Check the error message. If it complains that jar is corrupted, check jar. If it complains about the class version check JRE version. If it throws ClassNotFoundException or ClassDefNotFoundError check classpath. If it throws NoSuchMethodException or similar check compatibility of your libraries.
3. To check jar file try jar vft your.jar (if you have JDK) or commands like unzip on linux or extract zip file on windows. If this does not work - jar file is corrupted.
4. If jar file runs on one machine and does not run on other check how did you copy the file. First check the file size on both machines. Use ls -l on unix or dir on windows. If files have the same size try to compare them by creating hash. Use md5sum my.jar on linux and tool like WinMd5 on windows. Other possibility is to copy file forward and back and check that it is still ok.
