They've send me a java code (written with Eclipse) that came in a zip. When decompressed, I had the following files:
- .settings
- org.eclipse.jdt.core.prefs
- bin
- anon
- Discovery.class
- Main$1.class
- Main.class
- Server.class
- src
- anon
- Discovery.java
- Main.java
- Server.java
- .classpath
- .project
- jssc.jar
When I try to execute the jssc.jar from the command line, I get a message saying no main manifest attribute. I have decompressed the jar file to see the manifest and what it contained:
- jssc: with lots of "class" files inside
- libs: with folders containing files for each OS
- META-INF: with a file manifest
So, it seems that there is a manifest. However, when I open it appears:
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.8.1
Created-By: 1.6.0_45-b06 (Sun Microsystems Inc.)
X-COMMENT: Main-Class will be added automatically by build
What should I do? How do I add the jar file to buildpath?
If you tried to execute it with the command: java -jar jssc.jar and it failed try to use the following command
java -cp jssc.jar anon.Main
The above will tell JVM to load jssc.jar in its classpath and then execute the main method in Main class.
Update: if the java program needs more classes than the classes exist in jssc.jar add them in the -cp option with ';' seperator character.
For example:
java -cp jssc.jar;bin/anon/;libs/a.jar;libs/;.... anon.Main
