[jcifs] Please Help Me!

[Aris Javier]

Hello!
 
I'm new here. I have a working app running in tomcat.
I also have a working code ("Getattr.java") to communicate to Active
Directory.
 
The thing is, i want to get first the logged-in username then i can 
verify using "Getattr.java" if the user exists in AD.
 
I'm following the instructions on "JCIFS NTLM HTTP Authentication"
I copied the jar file in /lib folder. and
I inserted this inside my application's web.xml :
 
 <filter>
     <filter-name>NtlmHttpFilter</filter-name>
     <filter-class>jcifs.http.NtlmHttpFilter</filter-class>
 
     <init-param>
         <param-name>jcifs.smb.client.domain</param-name>
         <param-value>EAZIX</param-value>
     </init-param>
     <init-param>
         <param-name>jcifs.netbios.wins</param-name>
         <param-value>192.168.63.1</param-value>
     </init-param>
 </filter>
 
 <filter-mapping>
     <filter-name>NtlmHttpFilter</filter-name>
     <url-pattern>/*</url-pattern>
 </filter-mapping>
 
 
but this error occured;
 
java.lang.ArrayIndexOutOfBoundsException
java.lang.System.arraycopy(Native Method)
jcifs.smb.SmbComSessionSetupAndX.writeBytesWireFormat(SmbComSessionSetup
AndX.java:118)

jcifs.smb.SmbSession.logon(SmbSession.java:80)
jcifs.http.NtlmHttpFilter.doFilter(NtlmHttpFilter.java:129)
 
I need help!
 
PS: without this filter, my web app runs fine.
 
Thanks in advance!
