DCEVM in existing jdk-11, on Windows #10

Closed electrotype closed 5 years ago

electrotype commented 5 years ago

What are the instructions to enable DCEVM in an existing JDK installation (jdk-11.0.2), on Windows? The libjvm.so lib of course doesn't exist.

I ask because I have an issue with the prebuilt version. I haven't been able to create a small/reproductible example yet, but the issue occures when using Guice and requestInjection(...). Some dependencies are not injected. Using plain jdk-11.0.2 works well.

Make dcevm direcotry inside lib/ andCopy server/libjvm.so (lib) to it.

@skybber I don't understand! There is no lib/libjvm.so in the Windows distribution.

Should I take it from the Linux distribution? I don't think ".so" libraries will work on Windows, do they?

I see now, JVM is on different path on windows :

https://github.com/dcevm/dcevm/blob/master/installer/src/main/java/com/github/dcevm/installer/ConfigurationInfo.java#L62

the server VM is in /bin/server/ so dcevm VM could be in /bin/dcevm/

I copied C:\java11-openjdk-dcevm-windows\bin\server\jvm.dll to C:\jdk-11.0.2\bin\server\jvm.dll

Nothing.

I also copied C:\java11-openjdk-dcevm-windows\lib\hotswap\hotswap-agent.jar to C:\jdk-11.0.2\lib\hotswap\hotswap-agent.jar

Nothing.

I then copied (overwrote) C:\java11-openjdk-dcevm-windows\bin\server\jvm.dll to C:\jdk-11.0.2\bin\server\jvm.dll

And now I get:

Yeah!

But I still get the error with Guice, sadly....

Thanks for the help.
