RE: trouble in starting tomcat
First, try starting tomcat with bin\tomcat run (note the parameter
run) - this will start in the same window and will keep the error on screen.
Second, the cause of your crashes is the JDBC-OBDC bridge. This
component is not thread safe. As soon as the second concurrent access is
attempted, a crash occurs. You must either serialize your requests
(completely, you can only have one connection object at a time) or find
another way to access your data.

Subject: trouble in starting tomcat
Hi,
I've been using tomcat 3.2.1 successfully on win2k with jdk1.2.2. I was
having frequent tomcat crashes fromt the time I started having jdbc-odbc
connectivity in my servlets. I was thinking of changing my JVM to avoud the
crashes. and Now before I made any changes, the tomcat doesn't start at all.
or maybe I should say, it crashes immediately(I just get the glimpse of the
window).
What to do?
Thanks in advance,
Lakshmi

It depends on what database you are using... I'll assumie it is
a) access (you should get a different DB)
b) sql server (merrant and others make JDBC drivers, search te web there
are a few options for sql server).

I've upgraded my jdk to 1.3.0_02. tomcat crashing problem has been solved.
Regarding the jdbc driver, can someone suggest me what kind of a driver I
need to get to support concurrent access. and where I can get it.
Thanks in advance,
Lakshmi
