OpenSAML user discussion

Hi,

I am using opensaml-2.3.0 library file and tomcatapache-tomcat-5.5.28 and 
java 1.5.The application is working fine with this configuration. But when I 
am trying to use jdk1.4 I am getting the following error.Because In our 
server Java 1.4 is installd.

type Exception report

message 

description The server encountered an internal error () that prevented it 
from fulfilling this request.

exception

Can anyone please tell me whether the Base64 class is compatible with jdk1.4 
or not. 

Thanks.
