Simple newbie problem: import 3rd party jar

[jodyflorian]

Hi,

I'm new to Java (2nd year Java student) and am like a headless chicken trying to use a third party jar file in my project.

I've tried googling for help but am clearly missing something - I would post what I've tried, but it would be pointless since I haven't really got anywhere! I would have thought this should be as easy as pie given Java's qualities but it would seem Java and stupidity are incompatible!!

Any help would be hugely appreciated!

I'm not clear what you are looking for. Adding a third party jar file to your project? What you mean third part?

Hi Eranga,

Thanks for your reply.

I have a JAR file that someone has written as a wrapper for a DLL. I would like to use the wrapper (4 or so methods) in my application.

The problem is, when I try to include the JAR using a java import statement in my code it can't locate the library.

Thanks again

Jody

Ok I think I've bumped into how to do it:

1) Create new project
2) Right-click project -> "import"
3) General -> File system
4) Open directory containing JAR file
5) Click the checkbox next to the JAR file, click OK
6) Right click on the JAR file ->
7) Build Path -> Add to build path
8) Then in the source, import the package name as listed under the JAR tree.

The build path was what I missed! (And I wasn't sure if I had to import the jar file, or if I had to add it to the project some other way).

1.Put the jar in your project in a folder called lib (make it if it does not exist.
2. right click on project >>Properties>>Java Build Path
3. Click on the Libraries tab
4. Add Jars, find the jar you just copied and click ok, then ok and the workspace should rebuild.

Yes, you can't add them directly as Java libraries do. You have to do few changes. All about that you get two replays. Read them and try.
