Hi, I have installed ZK on WebLogic 8.1.

I am getting the following error stating that WebLogic cannot load zkLoader.
Looks like ZK is looking for JSTL1.1. Since WL 8.1 supports JSP 1.2 and JSTL 1.0 only, what should I do?

a) web.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC '-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN'
'http://java.sun.com/dtd/web-app_2_3.dtd'>

<web-app>
...
<servlet>
<description>
ZK loader for evaluating ZK pages</description>
<servlet-name>zkLoader</servlet-name>
<servlet-class>
com.potix.zk.ui.http.DHtmlLayoutServlet</servlet-class>
<!-- Must. Specifies URI of the update engine (DHtmlUpdateServlet). -->

<init-param>
<param-name>update-uri</param-name>
<param-value>/zkau</param-value>
</init-param>

<load-on-startup>3</load-on-startup><!-- MUST --> </servlet>

Error:

<Servlet: "zkLoader" failed to preload on startup in Web application:
"springapp".
