jcr-rmi: RemoteRepositoryException

[tak]

Hi,

The Exception occured when
I coded sample program connecting alfresco by jcr-rmi extension.
However sometimes exception occurs the other time program is normally executed.
Anyone can tell me why?

stacktrace:

org.apache.jackrabbit.rmi.client.RemoteRepositoryException: Error unmarshaling return; nested exception is: 
   java.lang.ClassNotFoundException: net.sf.acegisecurity.AuthenticationCredentialsNotFoundException (no security manager: RMI class loader disabled): Error unmarshaling return; nested exception is: 
   java.lang.ClassNotFoundException: net.sf.acegisecurity.AuthenticationCredentialsNotFoundException (no security manager: RMI class loader disabled)
   at org.apache.jackrabbit.rmi.client.ClientProperty.getValue(ClientProperty.java:139)
   at sample.FirstJCRClient.showNodeInfo(FirstJCRClient.java:118)
   at sample.FirstJCRClient.main(FirstJCRClient.java:79)‍‍‍‍‍‍

sample program is just like below.

package sample;

it is the same situation as above.
Sorry for double posting.


my testing environment is alfresco community network 2.1RC on both OSX and WinXP.
