JNI4Net C＃与Java [英] JNI4Net C# To Java
问题描述
我 jniBridge.Calculator 称为一个简单的Java类，它有一个简单的方法添加（INT A，INT B）。使用eclipse生成项目后，我出口项目作为一个JAR文件。
I have a simple Java class called jniBridge.Calculator that has one simple method Add(int a, int b). After building the project using eclipse, i exported the project as a JAR file.
然后我呼吁JAR文件proxygen，这产生一个名为 JVM 分别在两个C＃和Java代理包含所谓的另一个文件夹。 Proxygen还创建了 build.cmd 和的.xml 的文件。
I then called proxygen on the JAR file, this produced a folder called clr and another folder called jvm that contained both the C# and Java proxies respectively. Proxygen also created a build.cmd and an .xml files as well.
之后，我跑了 build.cmd 就产生了 .DLL 和 .JAR 文件。
After that i ran the build.cmd it produced a .DLL and .JAR file.
现在我想用这些或任何在C＃中，所以我复制的.DLL和.jar文件到在.NET项目文件夹，并添加到 .DLL 文件的引用并设置 .JAR 文件复制到复制始终来输出文件夹，以便它沿侧存在的 .EXE 文件。我还添加了一个参考Jni4Net主库文件 jni4net.n-0.8.6.0.dll 并复制其主要的JAR文件， jni4net.j- 0.8.6.0.jar ，到同一目录。添加到转储，我还增加了原来的JAR文件我开始。
Now i want to use these or whatever in C#, so i copied the .DLL and .JAR files into the .NET project folder and added a reference to the .DLL file and set the .JAR file to Copy Always to the output folder so that it exists along side the .EXE file. I also added a reference to the Jni4Net main library file jni4net.n-0.8.6.0.dll and copied its main JAR file, jni4net.j-0.8.6.0.jar, to the same directory. Adding to the dump, i also added the original JAR file i started with.
在C＃的Program.cs 我执行以下操作：
Inside the C# Program.cs i do the following:
BridgeSetup bs = new BridgeSetup();
bs.AddAllJarsClassPath(".");
Bridge.CreateJVM(bs);
Bridge.RegisterAssembly(typeof(jniBridge.Calculator).Assembly);
不过，最后调用失败，出现以下异常：
However, the last invocation fails with the following exception:
未处理的异常：net.sf.jni4net.jni.JNIException：无法加载Java类的jnibridge.Calculator从类加载器sun.misc.Launcher$AppClassLoader@e39a3e --->抛出java.lang.ClassNotFoundException：jnibridge.Calculator
Unhandled Exception: net.sf.jni4net.jni.JNIException: Can't load java class for jnibridge.Calculator from classLoader sun.misc.Launcher$AppClassLoader@e39a3e ---> java.lang.ClassNotFoundException: jnibridge.Calculator
任何帮助，请！
推荐答案
我有这个问题，并固定在我的Java代码中设置小写包名（也是在C＃线束参考命名空间）。在你的情况，你可以尝试并确认包名字是（完全一致）jnibridge（不JniBridge或其他任何东西）。
I had this issue, and fixed it setting the package name in lowercase in my Java code (and also the reference to the namespace in your C# harness). In your case, you might try and confirm the package name is (exactly) jnibridge (not JniBridge or anything else).
