Is it possible to debug a Java program running in jni4net?

问题

I'm currently using a Java library via jni4net in a C# application running on IIS Express, and the Java library is throwing an exception. Is it possible to attach a debugger to debug the Java code?

Attempt: I tried to add the following to the JVM options as per the instructions provided by IntelliJ:

setup.AddJVMOption("-agentlib", "-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005");

but get an exception:

Unable to open debugger port : java.net.ConnectException "Connection refused: connect"

回答1:

By setting the AddJVMOption-String to: setup.AddJVMOption("-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=1044");

I am able to connect to the jni4net part via Eclipse, maybe you should just omit the first argument ("-agentlib", ...)

When I use setup.AddJVMOption("-agentlib", "-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005");

I get an Exception in CreateJVM
