How to put together OneJar, UberJar without source code

[Imre Tokai]

Hello,


How can I put couple of jars together in 1 jar file?

That would be OneJar or UberJar, if I had the source code, but i don't have it in this case

main.jar (here is the main class)
dependant_jar1.jar
dependant_jar2.jar
.
.
.

Just jar them up as you would any other resource.

Be aware that jars contained in jars are not on the classpath. If you need them to be you need to implement your own class loading logic.

I'm not sure what you're asking - that's exactly what OneJar does; are you asking how you can use it? If so, there's documentation on its web site. If you're asking something else, tell us exactly what that is.

Thanks, experience with OneJar is welcome!

I suggest you read the "Quick Start" section - it explains what jar files you need and how to use them.

Appreciate your fast response(s) a lot!

When I walkthrough the Command-Line Approach guidelines, I get one-jar.jar that contains only META-INF folder? What am I doing wrong?
Can anybody share precise guidelines on success generation of 1 jar, please?
What if additional resources are involved (images, i18n, internal DB...)?

Hello,
Found this old thread and it might turn out useful...

So OneJar generates executable jar (involving other jars) together with image-icon from the resources, as expected

Further, does anyone know how to setup, read and update a config file for OneJar? Where to put it exactly and how to reference it? getResourceAsStream should be used, i guess, but how?

P.S.
Don't want to miss-lead with below unsuccessful tries:

Properties prop = new Properties();     
prop.load( new FileInputStream( pConfFilePath ) );	
prop.load( RunThisClass.class.getResourceAsStream( pConfFilePath ) );
prop.load(Thread.currentThread().getContextClassLoader().getResource( pConfFilePath ).openStream());	    		
prop.load(Util.class.getClassLoader().getResourceAsStream(pConfFilePath));	    		
prop.load(RunThisClass.class.getResource(pConfFilePath).openStream());

Hello,
Encapsulating config.properties file in .exe and assembling all as installer is also an option.
Any experiences? Which (non-commercial) tool would you recommend?
