To run it, just do: mono Demo.exeīut we can go one step further.
#Compiling java program with jar code#
The above compiled the code directly into a a Mono/.NET executable. NET code, which will skip the double JIT process: $ ikvmc -reference:`pwd`/classpath.dll Demo.class gtk-sharp.jar The next step is to precompile the Java code directly into. The above is basically translating Demo.class from JVM bytecodes to ECMA CIL, then the Mono JIT translates that into native x86 code. To compile, you will need to reference the libraries we created before: $ javac -classpath 'gtk-sharp.jar:glib-sharp.jar:atk-sharp.jar: Window w = new Window ("Hello Mono with Java#") We will now add some meat to the program, this is a slightly more interesting sample: import cli.Gtk.*
#Compiling java program with jar free#
The above just sits there waiting for events, so feel free to kill that. Now, it is not possible to run this directly in Java, since the jar files produced by netexp.exe are only stubs, so we will need to run this in the Mono world using IKVM in JIT mode: ikvm -classpath. The -classpath file instructs the Java compiler to find the type definitions on the gtk-sharp.jar file that we had previously produced with ikvmstub. This produces a Demo.class file that contains the Java bytecodes. To compile the above program type: javac -classpath gtk-sharp.jar Demo.java This is a very basic Java program that initializes Gtk#: import cli.Gtk.* So if you had a class called “Gtk.Window”, it will be exposed to Java as “”. The ikvmstub program will import all of the types into the “cli” namespace. The above commands basically “imports” all of the types and their definitions into something suitable for Java to consume, the result is: $ ls *.jarĪtk-sharp.jar glib-sharp.jar gtk-sharp.jar mscorlib.jar Ikvmstub /mono/lib/mono/gtk-sharp/atk-sharp.dll Ikvmstub /mono/lib/mono/gtk-sharp/glib-sharp.dll Ikvmstub /mono/lib/mono/gtk-sharp/gtk-sharp.dll This is done using the netexp.exe program from IKVM, like this: ikvmstub /mono/lib/mscorlib.dll It is necessary first to generate some stubs for these classes to let the Java compiler knows about the types defined in the C# world. NET assembly (this is the ECMA lingo for “library”), and Java does not know anything about this. NET framework can use it today and because it covers more than only the Gtk API, it covers various other components of the GNOME Development Platform. Because Gtk# is not limited to C#, any programming language in the. We are going to build some samples using Gtk# But this means that at runtime you are compiling things twice: the Java-to-CIL JIT and the CIL-to-Native JIT. There are two possible ways of using IKVM: one is to use it as a Just-in-Time compiler which translates the Java bytecodes into. As it stands today, it is able to run popular applications like Eclipse and Derby. IKVM is fully supported by Mono and its part of the standard Mono package distribution. The class library runtime for IKVM is the GNU Classpath, which is rapidly advancing but not entirely complete. Zoltan Varga ported it to Mono and fixed the Mono runtime to support the features required by IKVM. IKVM was developed by Jeroen Frijters for the.

This is done with IKVM the Java VM implementation that runs on top of. Mono is able to run Java code side-by-side with.
