Thanks for all reply. Now what I did is I compiled only one source file and made a jar out of it which contains only one ArrayExample.class file. Once JAR available then I unzipped that JAR and edited the manifest file as per your suggestion but still I am getting same error.
Please find the attached java source file and manifest file. Please help Regards Irfan. -----Original Message----- From: Taj, Abdul [mailto:[EMAIL PROTECTED] Sent: Wednesday, June 18, 2008 6:23 PM To: Ant Users List Subject: RE: unable to execute JAR file Does the jar have a manifest file that specifies the main class that needs to be executed when you execute it? When you create a jar it will have a META-INF directory inside which you need to place a manifest file that has the main class that needs to be executed when you execute the jar file. Just google about the manifest file and you will get your answer -t ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Wednesday, June 18, 2008 3:26 AM To: user@ant.apache.org Subject: unable to execute JAR file Hi All, I have 10 java files and I have written Ant build.xml to compile and create JAR file which contains the .class files.
