java.net.MalformedURLException: unknown protocol: rsrc

问题

I get this;

java.net.MalformedURLException: unknown protocol: rsrc

I'm not entirely sure what to do about this unknown protocol. I am using simple RMI to communicate between two JVMs. Is it a jar that I am missing that contains this protocol and, if so, which one? I haven't found Google searches to be all that great for this issue.

Any help would be appreciated. Thanks.

EDIT2: To clarify, my RMI code works when running from Eclipse. It's when I export and use runnable jar files and such that it breaks.

EDIT: Here's a code snippet:

registry=LocateRegistry.getRegistry(
                rmiServerAddress,
            (new Integer(rmiServerPort)).intValue());

回答1:

I finally figured it out. When using Eclipse and exporting a runnable jar file, make sure to choose under Library Handling:

Extract required libraries into generated JAR

That will fix this particular issue and probably many others.

Sorry, it's already too late on this side of the globe and I missed the your phrase! :-) What about this issue? Basically, is the server running from a path in the filesystem with spaces in the pathname?

回答3:

this option definitely works: Export > Runnable Jar File > Copy required libraries into a sub-folder
