Subject Re: cvs commit: xml-axis-wsil/java/src/org/apache/wsil Base64Converter.java
Date Sat, 02 Nov 2002 01:20:42 GMT
Can we move the Base64 stuff into a some commons thing? We first
put this into APache SOAP, now there's a version in Axis, WSIL
and maybe even WSIF? The original code was copied from Xerces ..

Sanjiva.
