JDBC setup
All I have is
Eclipse with JDK
Tomcat 5.0.28
Now I need to set up a JDBC connection (to connect to
Sybase)
Should I download Jconnect for this ?
How do I define a resourse Reference ?
Should this code be in web.xml under conf.
If I do this with admin tool does that work ?
Thanks
D

GC Behavior
Posted by sysdba <sy...@ohiointernet.us>.
Could someone with a good understanding of gc in Tomcat 5.0.30 explain what
the normal behavior is. It appears that dead sessions are not collected
until the allocated heap is totally used up, and then it frees only 20 to
30MB. By my rough estimate, there should be at least 128MB of expired
sessions in there using Xmx512m.

If you use relative URLS (with ..) on tour site - it is probably a bad(not
evil, just poorly written) bot impersonating IE.

Always good to see people reading their logs.

You could look that IP address up, try either dig or nslookup (or on Mac
OS X there iseven a GUI network utility with an easy interface to
looking up domain names).

If every /.. is balanced by a preceding /Myapp, that's going nowhere in
particular fast. I'd explain it, but calculate the path out yourself.
Then check it from outside, say, from your home box, just so you get
comfortable with it. Try putting an extra ../ various places.
If the path substring were 32Kbytes long or longer, you could guess it
was an attempt at hiding a buffer overflow. Also, attempts at getting a
shell on a MSWxxx box tend to end in command.com or something.lib, so it
doesn't look like that.
The one remaining danger, if /hosting.html is supposed to be restricted
access, it might be an attempt to hide an access to it.

Bleagh. Talk about a browser no one should be using any more, ...

Like I say, you can always put the url together from your logs and try
it from an external box to see.
Paranoia is good. But you should follow up on it yourself.
