Hi all, I've already submitted a ticket for appengine. Finally, after a deeper study, I found the problem:
Using: java sdk-1.6.1 Backend instance startup will fail if you have a welcome file listed with same extension in JSF Servlet url-pattern. Example: 1) <url-pattern>*.html</url-pattern> <welcome-file-list> <welcome-file>index.xhtml</welcome-file> <welcome-file>index.html</welcome-file> <--- same as url-pattern </welcome-file-list> Result: FAIL 2) <url-pattern>*.html</url-pattern> <welcome-file-list> <welcome-file>index.xhtml</welcome-file> </welcome-file-list> Result: SUCCESS! I ran an exhaustive routine for isolate the problematic variable. The data collected is: 1 - *.app / welcome file list {index.html, welcome.xhtml} - OK 2 - *.app / welcome list {index.html, welcome.xhtml} - OK 3 - *.app / welcome list {index.html, welcome.xhtml, index.app} - Failed 4 - *.app / welcome list {index.html, welcome.xhtml} - OK 5 - *.app / welcome list {index.html, welcome.xhtml, test.app} - Failed 6 - *.xhtml / welcome list {index.jsp, index.html} - OK 7 - *.xhtml / welcome list {index.jsp, index.html, welcome.xhtml} - Failed 8 - *.html / welcome list {index.jsp} - OK 9 - *.html / welcome list {index.jsp, welcome.html} - Failed Explanation: a. *.app or *.xhtml or *.html Extension used as url-pattern for JSF Servlet. b. welcome list { ... } Files listed as welcome files. c. OK / Failed Result. OK for success and Failed for non success -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
