Problem using struts-example.war with J2SDKEE1.3(beta)

[Thai Thanh Ha]

 I can't use struts-example.war with J2SDKEE1.3(beta). The JSP pages work
normally, but when I use *.do, server always returns:



HTTP Status 404 - /editRegistration.do
The requested resource (/editRegistration.do) is not available. 

What's wrong? Please help me! I know that J2EESDK isn't a good enviroment
for development. But I must use it :-(

 Regards,
 Thai
