Re: Is it Tomcat problem or my problem?
Uma,
How did you manage the session? Are you using container managed security? From
your description, it seems that you manage sessions yourself. If that's the
case, make sure you create a new session at login and invalidate session at
logout ...

I tried to print the session ID and to find out if the session is new by
these statements
System.out.println("session ID "+session.getId());
System.out.println("session isNew "+session.isNew());
For the first time when I entered betform.jsp it gave me
session ID BC45E3915B4AC4E188E7E84D1AEC4E15
session isNew false
When I clicked on other links in the same betform.jsp, then it gave me this
info
session ID 9D0D8E423E875D6ED1D79770B2CB48CC
session isNew false
and I was logged out. I logged in again and seen the output. Its
session ID 9D0D8E423E875D6ED1D79770B2CB48CC
session isNew false
and when I clicked on other links in the same page it gave me the same
session ID.
session ID 9D0D8E423E875D6ED1D79770B2CB48CC
session isNew false
I am really getting frustated with this Tomcat. Any help would be great.
Thank you,

What if the client has disabled cookies?
In my coding adventures, I've tracked down two "Hey my session

I dont understand by what you meant by the above lines.

When debugging a session problem, I find it very helpful to force my

JSESSIONID cookie being set, and can inspect things like the domain and
the jsessionid value.

The Login page is itself the Homepage of the site.
I tried to print the session ID and to find out if the session is new by
these statements
System.out.println("session ID "+session.getId());
System.out.println("session isNew "+session.isNew());
For the first time when I entered betform.jsp it gave me
session ID BC45E3915B4AC4E188E7E84D1AEC4E15
session isNew false
When I clicked on other links in the same betform.jsp, then it gave me this
info
session ID 9D0D8E423E875D6ED1D79770B2CB48CC
session isNew false
and I was logged out. I logged in again and seen the output. Its
session ID 9D0D8E423E875D6ED1D79770B2CB48CC
session isNew false
and when I clicked on other links in the same page it gave me the same
session ID.
session ID 9D0D8E423E875D6ED1D79770B2CB48CC

Re: Is it Tomcat problem or my problem?
Uma,
A few things to check.
Does it act the same from other machines?
Does it act the same from other browsers(Modzilla, Netscape, etc)?
Were any updates applied to the machine? Is auto update enabled on windows?
Are the connections via http or https?
Also try one more thing, on the first access do not use the URL of the
login, instead use the URL of the homepage and let it redirect you to the
login.

Doug,
Thank you for the reply. I dont think there is a problem with the Windows
Explorer as the same application worked great till yesterday. I never
changed the code and today it started not to work. I found the problem. The
problme is not in the Servlet, its in the JSP itself. The object in the
session is getting null. I have done the following test procedure and
checked it. My code for betform.jsp is posted below
1. Opened a new browser
2. Entered the Login URL and logged in (Servlet takes care of login
validations and puts the login info into a session)
3. I come to home page of the site.
4. I click on betform.jsp which has an Applet within it. The applet talks
to database for every 3 seconds for some information. I have several links
within the betform.jsp which will again call the same jsp with different
data.
5. I click on some link (any link) in betform.jsp, the session is not valid
and sent to login page.
6. I dont close the browser and login with the same browser and follow the
steps above, now the session works great.
Where am I going wrong? Why is the session not working for the first time
and is working now. I am using Tomcat 5.0.19
Any help would be great.

Re: Is it Tomcat problem or my problem?
Uma, Only cause you asked nicely. Not sure on this one. It may be that you have two problems or one causing both issues. Lets look at the IO error first. I am going to assume a windows environment from the E:\ prompt. You need to check the disk and the path to see if they are still valid. Do this from a prompt. Don't use explorer for this. See if you can find the same path. If yes then go into Windows Explorer and check the permissions on this folder. Check to ensure the parent propagation is unchecked for the Tomcat directory. Otherwise if someone makes a change to E:\ it will propagate down through all the directories. If it is there and you have proper permissions then your problem may be in Tomcat. Check your Windows logs. See if there are any errors. You could have a bad or full disk. If quotas are turned on you may have hit the limit. Worst case write a small java app that reads from a file and writes to a file in the directory and run it from the command prompt. If it fails then your problem is not Tomcat, at least for the file IO. For the null pointer issue. What is line 54 in the servlet trying to do? This is your first clue. Are you trying to read in from a file by chance? Need some more details in order to help further. A code snip here would help, or at least a description of what the servlet is trying to do just before and on line 54.
