Re: Using Realm

[Hemant Singh]

Sorry to be little bit unspecific in my question,
I was talking abt MemoryRealm,
but i don't want to load it from conf/tomcat-users.xml but from some
different flat or xml file.
Is that possible ?

Session & Cookie relation

[Hemant Singh]

HI ALL:
I found  a strange problem which i later solved after  a lot of debugging,
If my servlet is setting a cookie than after closing and reopening and
giving new hit from browser give me two different session values, that is if
i access session without reading cookie than i get different session value
than i get when i access session after reading cookie.
Is it some feature which i was unaware of  that?
Thanks all,
Hemant Singh

Re: monitoring using apache-tomcat

[Hemant Singh]

HI Aswath:
In your scenario you can use any one of following two solutions:
 - Run a thread in servlet and keep giving to hits to database after
particular time period
   but this is going to increase no. of hits on DB and load on server
running servlet, and unnessary network bandwidth consumption.
-  If your database (Oracle) allow Loading a class file than you can call
this class file from a trigger which should get fired when there is any
updates in DB, and on update this class file will call servlet and let him
know abt changes accordingly

Re: get/setAttribute and getParameter...

[Hemant Singh]

HI Zinger:
answer to this question depends on env conditions
setAttribute method stores the attribute in JVM itself for every session,
while set parameter will pass the attribute as a header information to you
new jsp.
So it all depends on memory available, cpu speed, and no of pages you are
going to use this technique.

In process conf with apache

[Hemant Singh]

HI ALL:
I tried conf apache with mod_jk.dll and it worked fine
with tomcat But it runs as out process,
and what i m looking for is that i do not need to run
tomcat as separate program and apache module itself
call it, that is in-process.
Cheers
Hemant

Re: Problem in access control of resources

[Hemant Singh]

HI Pankaj:
How you transfer the word documents to the client? 
I mean you expect user to download it, or view it in there web 
browser?
In both ways what you can do is that instead 
of redirecting the client to word files, you read those word files in your 
jsp or servlet and write that file to users stream, And as you jsp or servlet 
will always have maintained in session(or whatever) that user has logged in or 
not, so i guess this will solve your problem.

Hemant

  Subject: Problem in access control of 
  resources
  Hi All,Servlet spec 2.2 statesI am using Apache and Tomcat to build my 
  website. The adapter is JServ.I have certain word documents which have to be 
  displayed on the browser on demand  from the end user. I dont want to end 
  users to view these documents unless they have logged into the system. What 
  happens right now is that user can see the url of word document when the jsp 
  redirects him to word document on receiving the request. He can then access 
  the document from the webserver even if he has not logged into the website. Is 
  there anyway I can prevent this from happening? Ideally I would like Apache to 
  serve all the word documents since they are static files. But I am also 
  considering Tomcat to serve this file.Also I have another question 
  on access control. Servel 2.2 spec states the followingAccess 
  control for resources: The mechanism by which interactions with 
  resources are limitedto collections of users or programs for 
  the purpose of enforcing availability, integrity, 
  orconfidentiality.How can we limit interaction with resources to 
  collections of programs?Any help on this would be greatly 
  appreciated.Thanks &

HI Randy and Milt:
I strongly believe that issue is not at all related to classpath,
As offcourse servlets are loaded by tomcat server, and in case they uses

HI:
If you have a jar which you are using in more than  one web-apps than place
it under
/tomat/lib
so that tomcat do not reload the same jar more than once(I really surprise
how internally it works)

and if you are using that jar only in one web-app than place than place it
under
/tomcat/webappps/yourwebapp/web-inf/lib

Re: Error in Startup Tomcat at Win2000

[Hemant Singh]

HI Peter:
you are getting the BindException, the most 
possible reason for this is that box you are trying to run tomcat already 
running some application which is using port 8080, so you try changing the port 
from 8080 to someother (In server.xml) and try running it again,

Re: Problem in access control of resources

[Hemant Singh]

HI Again Pankaj:
When it comes to rendering of browser, i will say 
it all depends on headers that you send it from servlet, if send the right 
header applicable for word ( i guess "application/doc", if not let me know i 
will checkout and find the correct one for u), than there is just no reason that 
why browser will not render it as a doc file,
But here you are not only making ur website 
platform dependent but also browser dependent as in case of IE it is offcourse 
capable of opening the word file as inprocess because of IE have a plugin for 
it, But what about Netscape, he will offcourse bring the dialog box asking the 
user that whether he wishes to download it or not(Whatever)
Regards
Hemant

  Hi Hemant,The user should have both the options to view it 
  or download it. The problem with streaming is that it is somewhat slow(since 
  you have to first read it and then write it in a stream).The second issue is 
  that for e.g. if I read a word document in a stream and then write it in a 
  stream , the browser doesnt know that its a word document and just renders it 
  as a txt document. In the case of word docs and xls the output on the browser 
  is all junk. Please let me know what you think on this.Thanks a lot 
  for your help Hemant.Regards,PankajAt 06:43 PM

you can do is that instead of redirecting the client to word files, you read 
those word files in your jsp or servlet and write that file to users stream, 
And as you jsp or servlet will always have maintained in session(or 
whatever) that user has logged in or not, so i guess this will solve your 
problem.Regards,Hemant

  Subject: Problem in access control of resources
  Hi All,
  Servlet spec 2.2 states
  I am using Apache and Tomcat to build my website. The adapter is 
  JServ.I have certain word documents which have to be displayed on the 
  browser on demand  from the end user. I dont want to end users to 
  view these documents unless they have logged into the system. What happens 
  right now is that user can see the url of word document when the jsp 
  redirects him to word document on receiving the request. He can then 
  access the document from the webserver even if he has not logged into the 
  website. Is there anyway I can prevent this from happening? Ideally I 
  would like Apache to serve all the word documents since they are static 
  files. But I am also considering Tomcat to serve this 
file.
  Also I have another question on access control. Servel 2.2 spec states 
  the following
  Access control for resources: The mechanism by which interactions 
  with resources are limited 
  to collections of users or programs for the purpose of 
  enforcing availability, integrity, or 
  confidentiality. 
  How can we limit interaction with resources to collections of 
  programs?
  Any help on this would be greatly appreciated.
  Thanks & Regards, 
  Pankaj 

Re: Java Question

HI Bran:
There is no relation betn static and synchronize

If you are synchronizing the static method than it
does means you are giving him the class level lock,
and not instance level lock.
Hope that help

Re: How can I make tomcat to instantiate a class

[Hemant Singh]

HI Ghosh:
Make a class based on singelton pattern, which handles
the all database functionality, place this class in a
jar and place it in
TOMCAT_HOME/lib
Now you all servlets can access this same class file
and so using same session, Not sure whether and how
jsp can use it, can someone here clear this?

Re: How to upload a binary file?

[Hemant Singh]

HI Folha:
The reason is because yur are using readLine function
in your program which can shuffle or make u loose some
bytes from the file, This is most likely to occur in
binary file, So you need to modify yur program so that
yu use read function instead of readLine and it will
definetely going to work

Re: multiple resultset

[Hemant Singh]

HI :
If yu are using more than one resultset at a time than
they MUST have there different Statement objects,
i.e if yu have created one ResultSet and without
closing it  yu are creating one more ResultSet n try
using previous one also, than this is a problem,
So what u do is make different Statement object for
them.
e.g 
ResultSet rst1 = stmt1.executeQuery("...");
ResultSet rst2 = stmt2.executeQuery("...");
And it will work

Download via servlet behaviour

Subject: Download using servletHI ALL:My 
company offers some of it products for download,but we allow only authorized 
user to access thesedownloads, and for this reason the download is done 
viaservlets (servlet stream writes the complete file at client end)but i 
m noting a strange thing in this, when user click on downloadthan a dialog 
on browser asking them to open or save the file,  nowif the user, 
clicks on cancel than also my servlet executes complete,though the user is 
infact not downloading the file, It must be becausethat servlet is called as

prevent this,Is there?Is someone else also noted or faced this
