Hi, Martin: I added a logging statement to the remove method in both RgbWSDFAttHome class and the PersistentRgbWSDFAtt class. According http://www.globus.org/api/javadoc-4.0/globus_java_ws_core/index.html
public void *remove*(ResourceKey <http://www.globus.org/api/javadoc-4.0/globus_java_ws_core/org/globus/wsrf/ResourceKey.html> key) throws ResourceException <http://www.globus.org/api/javadoc-4.0/globus_java_ws_core/org/globus/wsrf/ResourceException.html> "If the resource implements the RemoveCallback <http://www.globus.org/api/javadoc-4.0/globus_java_ws_core/org/globus/wsrf/RemoveCallback.html> interface the RemoveCallback.remove() <http://www.globus.org/api/javadoc-4.0/globus_java_ws_core/org/globus/wsrf/RemoveCallback.html#remove%28%29> operation will be called." I overwrote the 'public void remove(ResourceKey key)' method in the RgbWSDFAttHome class anyway. But still could not see the remove logging information. I did see the create() logging information within the same class. I also tried with the Counter service originally packaged in the source code and all timeout are set to 120000( 2minutes). They have the same problem.
