Hi,
BEA WebLogic JSP supports the JSP 1.2 specification from Sun Microsystems. JSP 1.2 includes support for defining custom JSP tag extensions. (See Programming JSP Extensions)
The WebLogic Server implementation of the JSP 1.3 specification calls getOutputStream rather that getWriter to output characters in a JSP. This can cause certain extended characters to be truncated and to appear incorrectly.
But as you asked for it, JSP 2.0 will be supported by WLS 9.0
