JBoss 4.2.1 EJB 3.0 compression marshalling

marcanthony May 24, 2013 3:25 AM

Hi All

I found thread 111378 and tried to enable compression marshalling but it doesn't seem to work. I have extended org.jboss.remoting.marshal.compress.CompressingUnMarshaller and org.jboss.remoting.marshal.compress.CompressingMarshaller with my own classes that have overridden implementations that print the size of the objects that are passed in to be serialized but for some reason the execution never reaches my code.

this is my config,


socket://${jboss.bind.address}:3873/?marshaller=MYCompressingMarshaller&unmarshaller=MYCompressingUnMarshaller

my classes are packaged in a jar and made available to client and server

thanks

Marc

Hi Marc,

Which version of Remoting 2 are you using? IIRC, there were problems in the compression marshaller/unmarshaller that eventually got straightened out. New versions of Remoting 2 are meant to be compatible with older versions, so upgrading shouldn't be a problem.

Hi Ron

thanks for getting back to me, eventually I got it working with jboss-remoting-2_5_4_SP4, less data is sent across the network, but when i shutdown the server I get a warning followed by an exception:

WARN [ServiceController] Problem stopping service jboss.remoting:type=Connector,name=DefaultEjb3Connector,handler=ejb3
java.lang.NoSuchFieldError: m_map
at org.jboss.remoting.transport.socket.LRUPool.getContents(LRUPool.java:81)
at org.jboss.remoting.transport.socket.SocketServerInvoker.cleanup(SocketServerInvoker.java:460)

ERROR [Connector] invalid Object Name
javax.management.InstanceNotFoundException: jboss.remoting:service=invoker,transport=socket,host=MYMACHINE,port=3873,marshaller=org.jboss.remoting.marshal.compress.CompressingMarshaller

I dont thinks it is a problem but was curious, I tried to debug but the field m_map exists...

A quick question , how do I achieve compression for ejb 3.0 in jboss 7.1.1

thanks

Hi Marc,

I'm glad you solved the problem.

As for the m_map field, I don't know what that's about. org.jboss.remoting.transport.socket.LRUPool is derived from a class, org.jboss.util.LRUCachePolicy, that comes from an external jar, jboss-common-core.jar. Remoting 2.5.4.SP4 is built against version 2.2.16.GA of jboss-common-core.jar. Maybe there's incompatibility with the version you're using.

Hi Ron

I will check out jboss-common-core.jar and see what I find, thanks for pointing me in the right direction.

Any advice for ejb 3 compression on JBoss 7.1.1 ?

thanks

Hi Marc,

JBoss AS 7.x uses Remoting 3, which is a whole separate code base. I don't know much about it, to tell the truth. Don't think there's much documentation, yet, either.'

You could try posting the question on the EJB3 forum (https://community.jboss.org/en/ejb3) or the AS 7 forum (https://community.jboss.org/en/jbossas7).
