Tomcat-Question: Inefficient searching for jsp-files?
Hello,
i am using Tomcat 5.5.23. When i request a simple jsp-file
my file-monitor shows me, that tomcat is searching from root.
This is a problem for website with a lot of traffic.
A screenshot is attached to this mail.
The Context-Entry looks like
<Context docBase="D:\inetpub\wwwroot\tyres4trade" path="" privileged="true"
workdir="...." reloadable="fals" />
Thanks for suggestions,
Thomas

I don't think tomcat(explicitly) is doing this. It could be any of the
following:
1) When the file is found a full path check is done to prevent sneaky
people from trying ../../ tricks - so I you might see the JVM and how it
implments File.getAbsolutePath) on a file
2) It could be IIS doing the checks and not tomcat
3) It could be the IIS jk plugin - but I'm not sure about that possibility.
4) ???
My vote is for #1

Have you tried observing any other programs when they load files? How
about a non-Tomcat Java process that attempts to load a file with a
specific path.
It's possible that Tomcat is reading the directories to make sure they
exist, so it can give you a good error message (if they don't).
If you re-request the same file, does it re-check? What if you request a
file that /does/ exist, and then re-request it? Does it re-check from
the root?
This is probably a question for the developer list.

Hi,
my contect-configuratation looks like:
<Context docBase="D:\inetpub\wwwroot\tyres4trade" path=""
privileged="true" workdir="...." reloadable="fals" />
when i request e.g. test.jsp from browser my file-monitor show
the following harddisc-accesses:
d:\
d:\inetpub
d:\inetpub\wwwroot
d:\inetpub\wwwroot\tyres4trade
d:\inetpub\wwwroot\tyres4trade\test.jsp
d:\inetpub\wwwroot\tyres4trade\localhost\test.jsp (not found)
<tomcat-root>\tomcat 5.5\work\org\apache\jsp\test_jsp.class
i ask myself why does tomcat start to search from d:\ instead of docBase?
