That is certainly more correct than my simplified explanation,
but,at this point, likely to confuse the OP a bit more, maybe ?

Quoting selectively from Petr's previous posts :
...
in the Catalina configuration directory
(/etc/tomcat5/base/Catalina/localhost/XYtest.xml) is following context

...
(now)
Apache things are in directory
/opt/test/htdocs
tomcat things are in directory
/opt/test/servlet

(/etc/tomcat5/base/Catalina/localhost/)XYtest.xml is now:
<?xml version='1.0' encoding='utf-8'?>
<Context docBase="/opt/test/servlet" allowLinking="true">
</Context>

And jsp are stored in
/opt/test/servlet/jsp/Viewer/View.jsp
...

end quote

and he didn't say -- but I presume --, that web.xml is in
/opt/test/servlet/WEB-INF/web.xml


So, Petr, to bring all this together :

1) in /etc/tomcat5/base/Catalina/localhost/XYtest.xml :

docBase="/opt/test/servlet"

2) in the Apache config :

ProxyPassMatch ^/XYtest/(.*\.jsp)$  ajp://localhost:8009/XYtest/$1

Because if you just use
ProxyPass /XYtest ajp://localhost:8009/Xytest
then a URL like "/XYtest/index.html" will also be passed to Tomcat, and Tomcat will not 
find it, considering the location of your "Apache things" above.

3) in the file index.html :
<frame src="/XyTest/jsp/Viewer/View.jsp" ...

Alternatively, you could do :

1a) in /etc/tomcat5/base/Catalina/localhost/XYtest.xml :

docBase="/opt/test/servlet"

2a) in the Apache config :

ProxyPassMatch ^/XYtest/servlet/(.*)$  ajp://localhost:8009/XYtest/$1

3a) in the file index.html :
<frame src="/XyTest/servlet/jsp/Viewer/View.jsp" ...

(in this case, the ProxyPassMatch directive will "strip" the "/servlet" part, which 
confuses Tomcat)


When (if?) the above is working, then I will suggest a better (and simpler) layout
for the files and directives.
