Subject RE: struts-el example app not working?
Date Thu, 31 Jul 2003 08:44:57 GMT
Yep, I've been bitten by this one too. There are a few workarounds:

1) Change the JSP compiler to not compile JSPs:
http://marc.theaimsgroup.com/?l=struts-user&m=105334711431267&w=2

2) Workaround by Brian Cross (at end of this thread) - this works well for
us:
http://marc.theaimsgroup.com/?l=struts-user&m=105147011604944&w=2

Hope that helps.

Hue.
