Hi,
1.
local variable requestPathMB = null (in Tomcat 7.0.14 requestPathMB =
"/invitations")
2. <welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
3.
As I wrote on the last mail, the problem is in
StandardContextValve.java in method:
public final void invoke(Request request, Response response)
throws IOException, ServletException {
...
Wrapper wrapper = request.getWrapper();
...
in Mapper class on line 988
// Rule 7 -- Default servlet
if (mappingData.wrapper == null && !checkJspWelcomeFiles) {
if (contextVersion.defaultWrapper != null) {
contextVersion.defaultWrapper is NULL.
in Tomcat 7.0.14 (where everything is OK) is not null.
in Mapper.java, on line 708, method:
private final void internalMap(CharChunk host, CharChunk uri,
String version, MappingData mappingData) throws Exception {
on line 725: contexts = hosts[pos].contextList.contexts;
there are 2 contexts:
1. [0]:name="", versions.MapperContextVersion.defaultWrapper not null
2. [1]:name="app", versions.MapperContextVersion.defaultWrapper is null
[in Tomcat 7.0.14, there are 2 contexts, too, but all have
defaultWrapper not null]
variable pos=1, context = contexts[pos];
selected context has defaultWrapper null, variable
contextVersion.defaultWrapper is null.
