Field proven

Built on top of the field proven DLR plugin available in the Sinapse platform (https://www.sinapsesystem.com), JCOBridge guarantees the best performance in JVM and CLR worlds integration.

Features

CLR - Available for .NET Framework (Windows only), 6 and 8 on Windows (x86/x64/Arm/Arm64), Linux (x64/Arm/Arm64) and MacOS (x86_64/Aarch64) (other platforms/architectures available on demand):

• Retrieve JVM Class both directly or like a developer can done using the .class keyword in Java
• Instantiate JVM object both directly or using dynamic feature of .NET
• Invoke static methods both directly on a previously retrieved Class or using dynamic feature of .NET
• Invoke instance methods both directly on a previously instatiated object or using dynamic feature of .NET
• Get/Set static fields both directly on a previously retrieved Class or using dynamic feature of .NET
• Get/Set instance fields both directly on a previously instatiated object or using dynamic feature of .NET
• Use dynamic access to write code in a seamless way as it is done in Java language
• Use specific interface to manage directly methods and fields
• Support classes to simplify bridging of Java classes from .NET
• .NET side is able to send back data to the JVM upon events
• Exceptions directly managed from the core and translable in .NET exceptions
• Management of User Interface controls, properties and events
• Able to integrate Java UI (AWT/Swing/SWT) into WPF/WinForms (from version 2.2)

JVM - Available for .NET Framework (Windows only), 6 and 8 on Windows (x86/x64/Arm/Arm64), Linux (x64/Arm/Arm64) and MacOS (x86_64/Aarch64) (other platforms/architectures available on demand):

• Retrieve CLR Type
• Instantiate CLR object
• Invoke static methods on a previously retrieved Type
• Invoke instance methods on a previously instatiated object
• Get/Set static properties on a previously retrieved Type
• Get/Set instance properties on a previously instatiated object
• Set Delegates
• Subscribe/Unsubscribe events
• Integrates WPF controls into AWT/Swing window
• Integrate WinForms controls into AWT/Swing window
• Integrate complex .NET Graphical user interfaces objects into AWT/Swing window
• Management of User Interface controls, properties and events

JCOBridge simple example

Imagine you have the following Java Class:

public class MyJavaClass 
{
    //Static member
    static public String myStaticJavaHelloWorld()
    {
        return "Hello Static World from Java!!";
    }
    //Instance member
    public String myJavaHelloWorld()
    {
        return "Hello World from Java!!";
    }
    //Instance member
    public double myJavaAdd(double a, double b)
    {
        return a+b;
    }
}

JCOBridge helps to use the previous Java class from C# to access both static and instance methods.

How to call Java code

Define a class that use the Java code:

class MyJavaUsingClass : SetupJVMWrapper
{
    public void Execute()
    {
        string hello = DynJVM.MyJavaClass.myStaticJavaHelloWorld();
        Console.WriteLine(hello); //Print "Hello Static World from Java!!"
        var myJavaClass = DynJVM.MyJavaClass.@new();
        hello = myJavaClass.myJavaHelloWorld();
        Console.WriteLine(hello); //Print "Hello World from Java!!"
        double result = myJavaClass.myJavaAdd(2.0, 3.0);
        Console.WriteLine("{1:0.0}",result); //Print "5.0"
    }
}

Add JCOBridge initialization before call the Execute method.

using MASES.LicenseManager.Common;
using MASES.JCBridge.C2JBridge;
using System;

static void Main(string[] args)
{
    MyJavaUsingClass JavaTest = new MyJavaUsingClass();
    JavaTest.Execute();
}
