This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
I want to make one jar file (A.jar) with my class file and the other jar files (B.jar & C.jar) I need to run. I am writing a test driver which uses the Jakarta Common Http Client, for which I need two jar files (B.jar & C.jar). My code runs fine if I have these Http Client jar files (B.jar & C.jar) somewhere and use set the classpath correctly. But I would like to place these two jar files (B.jar & C.jar) into the jar file I am making (A.jar), so that installing all this will be simpler. I am using Ant and am able to create the jar file (A.jar) with the class file and Http Client jars (B.jar & C.jar). The problem comes when I try and run. I am creating the MANIFEST.MF file within my Ant jar task and setting my classpath there:
But when I run this I get:
Any ideas? [ March 18, 2004: Message edited by: William Barnes ] [ March 18, 2004: Message edited by: William Barnes ]
Please ignore post, I have no idea what I am talking about.
java.net.MalformedURLException: unknown protocol: commons-httpclient.jar That's because you have an ill-formed Class-Path in your manifest file. They aren't supposed to be colon-separated. But yes, you cannot use jars-within-jars. The Class-Path entry will look in the same directory for those jars, not for those jars inside this one.
I do something similar in my project by extracting the other .jars during he Ant build then jarring everything up into one .jar. Here is the relevant section of my Ant build. In it, I extract 4 .jar files and bundle my classes wit htheir contents:
Ok, so I go here: link and most of the legal stuff is talking about me changing the Jakarta code - which I am not doing. I am just using it. Finding the legal stuff which I think is talking about me the following needs to be included:

Where exactly I am suppose to include this isn't clear to me. How about if I create a README and put that into the jar? I don't see any legal language which said I couldn't use the class files outside of the jar. I guess I don't see how putting the class files into my jar is that much different than using their jar files. I am not trying to hide anything. If you look in the resulting jar it would have entries like this:
I am just trying to understand this. I don't want to do anything to break the license.

Depends on the license, but, in my case, it does NOT violate the licenses. Some licenses allow you to distribute/use the binary code in your own apps as long as you include their license with your app. Your mileage may vary. brian
William, it is all stated in section 4 of the license
