FW: Working with the class server

Ok, got it. my bad.

The installverify class path is not designed to look at the lib folder as
its own class path.

Now it works fine.

 

Thanks

I also tried putting the entries jar on the lib folder of the installverify
jvm.

Yet, I get the following exception when I tried to add the entry as lookup
attributed of the java space.

 

java.rmi.ServerException: RemoteException in server thread; nested exception
is: 

       java.rmi.UnmarshalException: unmarshalling method/arguments; nested
exception is: 

       java.lang.ClassNotFoundException:
jini.javaspace.testing.entries.JavaspaceTaggingEntry

Perhaps you can check to ensure your writer JVM has defined a codebase that
can serve the jars in question. This is most likely the issue you are
encountering.

Hi Asaf,

 

In general what you need to do is to set a Codebase server.

BTW, in Gigaspaces we found out that setting such server is not scalable and
in fact many times acts as a single point of failure.

So, what we developed (which is also available as part of our community free
addition) is a dynamic class loader.

 

Once the space stores an instance of an Entry (or an Entry's field) the
class is dynamically stored in the space and seamlessly provided to the
"taker" when needed.

I need some clarification on how to employ the class server.

I have a couple of jvm's. one writing entries and the other taking them.

The entry class I'm using is very simple:

 

import net.jini.entry.AbstractEntry;

public class JavaspaceTaggingEntry extends AbstractEntry{

                private static final long serialVersionUID =
-1559963129857857100L;

                public String myName = null;

}

 

The writer jvm, naturally has the entry class definitions in its class path.
The taker doesn't.

I tried putting the entry jar into the lib-dl folder under the jinni started
kit and made sure the Class Server server points to it so it would be
available through it.

The problem is that when I attempt to take the entry, I got a class not
found exception.

 

What is the right way to employ the class server?
