Description Ralf H. 2008-10-17 07:19:37 UTC
We are using "jcifs-1.2.22" in the following environment:

OS: Windows 2003 R2 SP2 english
Tomcat: 5.5
JDK: Bea jrockit-R27.5.0-jdk1.6.0_03
AD-Domain: Windows 2000

Infrastructure:
two WINS and three DC (Domain Controller)


We have the following filter-configuration for our webapplications:

web.xml (1):
<filter>
 <filter-name>NTLM HTTP Authentication Filter</filter-name>
 <filter-class>jcifs.http.NtlmHttpFilter</filter-class>
 <init-param>
  <param-name>jcifs.smb.client.domain</param-name>
  <param-value>MyDOMAIN</param-value>
 </init-param>
</filter>
<filter-mapping>
 <filter-name>NTLM HTTP Authentication Filter</filter-name>
 <url-pattern>/*</url-pattern>
</filter-mapping>

web.xml(2):
<filter>
 <filter-name>NTLM HTTP Authentication Filter</filter-name>
 <filter-class>jcifs.http.NtlmHttpFilter</filter-class>
 <init-param>
  <param-name>jcifs.netbios.wins</param-name>
  <param-value>20.x.x.1,20.x.x.2</param-value>
 </init-param>
 <init-param>
  <param-name>jcifs.smb.client.domain</param-name>
  <param-value>MyDOMAIN</param-value>
 </init-param>
</filter>
<filter-mapping>
 <filter-name>NTLM HTTP Authentication Filter</filter-name>
 <url-pattern>/*</url-pattern>
</filter-mapping>

Sometimes the following error occures during processing each web-request and as a result we have to reboot the Tomcat service OR - if the error still occures - the whole machine:

SEVERE: Servlet.service() for servlet jsp threw exception

My sourcecode inspections lead me to the assumption that you have an error in the following code/class:

NbtAdress.java @ lines 533 and 545
return NBNS.length == 0 ? null : NBNS[nbnsIndex]; 
should be:
return NBNS.length < nbnsIndex ? null : NBNS[nbnsIndex]; 

AND/OR in the calculation of the nbnsIndex


Best regards,
