Hy all,
I don't know if someone as already tested to work with JSF and MyFaces on its WebAS (Web Application Server of SAP).
In fact I've started by developping a simple JSF page
and next I would like to add some sweet component by using MyFaces and Tomawakh.
For the JSF page, no problem, it rulez, but, when I just add "myfaces-api-1.1.3.jar" and
"my-faces-impl-1.1.3.jar" and deploy it to my server.
No error during deploying but when I'm trying to open a
JSF page I get this long error :
#1.5#000D606F6C2B0026000000270000137800041B1DE87681AB#1155715175094#com.sap.engine.services.servlets_jsp.server.jsp.JSPParser#sap.com/NewsDisplayJSFApp#com.sap.engine.services.servlets_jsp.server.jsp.JSPParser#Guest#2####2839db702cfd11db94ff000d606f6c2b#SAPEngine_Application_Thread[impl:3]_12##0#0#Error#1#/System/Server#Plain###Runtime error in compiling of the JSP file <D:/usr/sap/DEP/JC00/j2ee/cluster/server0/apps/sap.com/NewsDisplayJSFApp/servlet_jsp/newsDisplayJSF/root/NewsError.jsp> !

I mean, in each JSP page I'm trying to use those standard taglib :
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
It crashes.
I've try to add in my web-inf/lib some jar like : servlet_api.jar, servlet.jar, and so on but nothing seam to be working. And also I've try to remove jar like : JSF-imp.jar and so one.
I've also try to define the extensionFilter of myfaces in my web.xml but it doesn't help me :(
Anyone has an idea ?
Thx.
