buildpath

I have a quick question about altering the build path as the code is running. For example, I have a class which downloads a .jar file from the internet and then into the same directory as the code is running from. How, if possible, could I load the jar into the build path to access the classes within the .jar file? Some suggested amendments / comments: Remove the jar: prefix and the !/ suffix - these are note required and are probably confusing the matter Can you verify the jar file exists: System.out.println(new File(new URL("file://test.jar")).exists()); Amend your class declaration to the

I'm having a problem with Eclipse on by Mac OSX Mountain Lion. I have recently installed Android SDK and in my java projects I get the following message: The type java.lang.Object cannot be resolved. It is indirectly referenced from required .class files Reading about this issue , it would seem that I do not have a valid JRE defined in the build path of my project.

I am having trouble setting up the build path of my java project. I am currently in a Co-Op IT position so I am somewhat new to all this. My background is mostly in C++ and I am learning java on the fly. I am also somewhat new to Eclipse (Kepler service release 1).
