Including .jar files in Unity

Question

Hello guys!

I have two lib files written in Java (two JAR files), and I would like to include them in my project.

Is that possible in C#/JS?

No, sorry. Jar files are Java "assemblies", not JavaScript.

Now, there are some utilities out there that claim to encode Jar files into .dll files, which might be includable in a Unity project. I have my doubts as to how well this will work out in reality, but it could be worth a shot.

The lead candidate for this is the IKVM bytecode compiler. More info here IKVM.NET

Thanks! It converted well, and at least Visual Studio recognizes the converted DLLs very well, but in Unity I'm using JS, how can I include it in JS?

Thanks!

I don't do much in JS myself, but it seems it should be as possible as for any other .NET libraries.

Take a look at the wiki on this topic. It's a bit down the page under the topic "Using $$anonymous$$ono (.NET)"

Long story short, it looks like you just need to import in the usual import LibraryName; manner.

I do note while hunting around that DLLs built from java are proving unreliable in builds other than Windows standalone. Do be sure to test your targets before going too far.

How can I use a DLL in JS anyway? I've tried several ways like:

var obj : ImportedObject = new ImportedObject() and var obj : ImportedObject = new dllName.ImportedObject()

But nothing seems to work......
