Re: Login Servlet

[Martin Smith]

public boolean next()
 throws SQLException

Moves the cursor down one row from its current position. A
ResultSet cursor is initially positioned before the first row; the first
call to the method next makes the first row the current row; the
second call makes the second row the current row, and so on.


Returns:
true if the new current row is valid; false if there are no more
rows
Throws:
SQLException - if a database access error occurs

 I guess there's a difference between an empty ResultSet and no ResultSet :)

As long as you remember to call response.encodeURL() around the value of
the action parameter on your form element, it will work fine.

i.e. if you were writing the element in a servlet:

writer.print("form action=\"");
writer.print(response.encodeURL("/my/action/url"));
writer.println("\" method=\"POST\");

Re: Tomcat and Jsp files

[nmlaney]

You've answered your own question, Tomcat does not see JSP files in the
Apache html root. You must put ALL JSP files in the Tomcat root directory
and ALL Servlets in the WEB-INF\classes directory OR setup up an
application context.

To setup additional contexts you use the same convention as the root:

# The following line mounts all JSP files and the /servlet/ uri to tomcat
JkMount /someApp/* ajp13
JkMount /someApp/*.jsp ajp13

Thus the JSP files go in webapps\someApp and Servlet files go in
webapps\someApp\WEB-INF\classes

applications with tomcat link at

Hi I am using Tomcat 3.2.1 and Apache on an Nt platform. My confusion is
this:
In http.conf file I have :

JkMount /*.jsp ajp12
JkMount /servlet/* ajp12

Should all the .jsp files be under the webapps directory? I have a jsp file

RE: oracle JDBC doesn't work

I think that (not being a DB guru):
   Connection  con =
 DriverManager.getConnection("jdbc:oracle:thin:storedb",
 "username", "password");
   }

should be more like:

...
DriverManager.getConnection("jdbc:oracle:thin:@storedb",
...

note the '@' between "thin:" and "storedb" (and the colon is necessary)

Our setup uses (though the format above may work for you):

"jdbc:oracle:thin:@abc.def.com:1521:SID"

where:
abc.def.com is the machine name
1521 is the port to connect to
SID is the database identifier.

Hope this helps.

 2. I downloaded oracle jdbc driver from Oracle.com. The

Re: A very weird problem

well we tried this on tomcat running on win9x box and it is getting added(!),
in log file you can see adding context /at though docBase points to some bogus

did u try to stop+start the server after adding these contexts ?

 The examples and test context does get loaded. I even tried to put the at
 directory out of the webapp directory and defined in the context in the
 server.xml file. But the "at" context doesn't load.
 The real weird behavior is that, when I rename the test directory to test1,
 the test context is loaded.
 I tried all kind of things like, creating a war file of "at", installing
 tomcat again. But can't fix this problem. Even the log file is not created
 under logs directory.

 I am really having very tough time with this, your help here is highly

Why is my init method run twice?

[Helgesen Hans Jørgen]

I'm new to this list, so please forgive me if this question has been raised
before

I'm running Tomcat 3.2.1, Apache 1.3.12, java 1.2.2 and Redhat 6.2.

I have a servlet to which I want to pass a single parameter via the web.xml
file (below). I'm obtaining the parameter value by calling
config.getInitParameter() in the init method of the servlet.

This seems to work fine, the init method is called and the value obtained OK
when Tomcat is started.

The problem is that when the first request for the servlet arrives, the init
method is run A SECOND TIME. This time the init parameter IS NOT AVAILABLE.

My theory is that Tomcat calls the init method once for each thread, but if
that is true, I would expect Tomcat to pass the init parameters each time?

What is wrong?

BTW, I can't get the servlet-mapping to work either. Any obvious errors?

Thanks,

 You can also specify a "randomClass" attribute, which determines

 By default this is "java.security.SecureRandom".
 Specifying "java.util.Random" will speed up Tomcat startup,
 but it will cause sessions to be less secure.

first thing is to check the log files , if it has something like:
loaded context /abcd
or not.if this context is loaded as per the log files then check the docBase
attribute of your context , whether it is pointing to correct physical directory
or not. and check for possible case-mismatch also.

Subject:Re: urgent help please

first thing is to check the log files , if it has something like:
loaded context /abcd
or not.if this context is loaded as per the log files then check the docBase
attribute of your context , whether it is pointing to correct physical
directory
or not. and check for possible case-mismatch also.

so you can do this with JSP's, but...

If you want the user to download the txt files, you have to tell the
server (Apache? Tomcat-standalone?) where to find these files by
creating an Alias directive or something else.

Hope it helps.

Is there a reason for Tomcat to use a 302 redirect? I think it would be

IIS/Tomcat Problems

[Mark Levy]

Hello,

I have been trying to use Tomcat through IIS and have run into some
problems.  After fixing my typos and removing the extra space from my
registry name I was able to get the green arrow up for my filter.  I then
tried to go to the examples page, and got the following debug output:

This is repeated several times as the browser just spins until it times out.
It also appears that some portion of IIS is hosed after this because I
cannot bring up the management console once I try it.

At this point I believe my configuration is correct, but I have no idea what
my next steps should be.

Any help would be greatly appreciated.

Thanks

Re: Tomcat-Startup in windows

Hi Shlomi,

I tried as you suggested but the nt service does not seems to work. I have
changed the tomcat and jave home to the appropriate path and can setup the NT
Service but it does want to start. I have tried to remove the Nt service using
jk_nt_service and add the NT Service but it still won't let me manually start
the service as it started in NT-Service-howto.html. The methods two that you
suggest works fine so I can't understand why the first method won't work.

My PC Config is:
Win 2000 Pro with SP1.
Apache 1.3 + Tomcat 3.2.1
wrapper.java_home=c:\jdk1.3.0_02
wrapper.tomcat_home="C:\Program Files\Apache Group\jakarta-tomcat-3.2.1"

in this way the tomcat will run as nt service , it will be loaded every time
after the the computer starts before the  login process
2. put your bat files in your startup directory (i am usint win 2000 :
C:\Documents and Settings\shlomi\Start Menu\Programs\Startup) you can right
click on your start menu button then choose open \ programs \ startup .
in this way the server will start after the user log in .

 I'm new to this list, so please forgive me if this question has been raised

 I'm running Tomcat 3.2.1, Apache 1.3.12, java 1.2.2 and Redhat 6.2.
 
 I have a servlet to which I want to pass a single parameter via the web.xml
 file (below). I'm obtaining the parameter value by calling
 config.getInitParameter() in the init method of the servlet.
 
 This seems to work fine, the init method is called and the value obtained OK
 when Tomcat is started.
 
 The problem is that when the first request for the servlet arrives, the init
 method is run A SECOND TIME. This time the init parameter IS NOT AVAILABLE.
 
 My theory is that Tomcat calls the init method once for each thread, but if
 that is true, I would expect Tomcat to pass the init parameters each time?
 
 What is wrong?

How are you calling the servlet?  I.e., via what URL?

Note that you can have different servlet definitions (servlet-name)
for the same servlet (i.e. servlet-class), and they are considered
different "instances", such that multiple instances of the servlet
class will be created (meaning init() will be called multiple times),
and only the parameters specified for each definition will be
available to that instance.  It looks like you only have one servlet
definition, but still, if you call the servlet via the class name
directly, it will create a separate instance.  E.g., from what you
have below, if you call /servlet/MyServlet and
/servlet/no.fellesdata.MyServlet, two separate instances will be
created.


 BTW, I can't get the servlet-mapping to work either. Any obvious errors?

What exact URLs are you trying?  What happens when you try them?
Perhaps you haven't specified the appropriate directives in your
apache/tomcat conf file to tell apache to pass it to tomcat for that
URL.

Re: Logging in tomcat

[Mark Mynsted]

I think the simplest way is to just use
application.log("This is a message to be logged");

This goes to the Servlet.log.  A little better maybe would be to define something like:
String logHeader = request.getServletPath() + ": ";

Then use
application.log(logHeader + "This is a message to be logged.");

This way the log message will be prefixed with the servlet generating the message.

The "application" variable is automatically defined for the service method.

I am a new user to the Tomcat world.

I haven't found much info on logging in tomcat. Is there somewhere I can go
to look up this info?

How does logging work in tomcat. If I write system.out's, will I see those
on the tomcat console? Or, does this have to go through logging? If so, how
would I invoke the logging mechanism?

I'm just interested in getting debug info out of Tomcat.

2. I downloaded oracle jdbc driver from Oracle.com. The downloaded driver is
Oracle 7 driver for NT. It has classes102.zip and classes111.zip and two
dlls.
3. I put calsses111.zip into c:\jdk1.3\bin and add "c:\jdk1.3\bin" to
CLASSPATH and PATH
4. test the connection in jsp as:
try{
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection  con = DriverManager.getConnection("jdbc:oracle:thin:storedb",

}
catch(SQLException e){

The username and password are good. I can make connection using jdbc-odbc

That is just microsofts external lock file so other programs
accessing the file do so in a friendly way.  Since access
has no database server the locks have to be shared somewhere.

The file should be small and you don't want to control it.

Re: Apache/Tomcat sendRedirect rpoblem

[David Wall]

 I've also had similar problems. I found that in nested if statements and
 if...else iterations, if you don't put a return after the sendredirect
 or forward it tries to execute the rest of the code...
 Matt Goss

As far as I know, servlet containers are not supposed to break the rules of
Java programming.  A sendredirect sends a redirect response to a client, but
it's not a return from a method call.  If you want to return after it, then
return.  Otherwise the correct thing a program should do is continue to the
next statement in the code.  Don't you think? wink

look there are couple of options
1. make the tomcat as nt service (NT-Service-howto , i am attaching this

in this way the tomcat will run as nt service , it will be loaded every time
after the the computer starts before the  login process
2. put your bat files in your startup directory (i am usint win 2000 :
C:\Documents and Settings\shlomi\Start Menu\Programs\Startup) you can right
click on your start menu button then choose open \ programs \ startup .
in this way the server will start after the user log in .

RE: Why is my init method run twice?

On Fri, 23 Mar 2001, Pradeep Kumar wrote:

 The Servlet specification says that, that the container should
 guarantee only one instance of the servlet. However some of the

 threads for 100 requests.  I don't know how far this is true with
 Tomcat. In general you should not make any assumptions about the
 number of instances of your servlet.

Actually, starting with the 2.2 spec, the spec is pretty specific
about the number of instances of each servlet that should be created.
Basically, if the servlet doesn't implement SingleThreadModel, it's
one instance per servlet definition; if it does implement
SingleThreadModel, then a pool of instances may be created to offset
the performance penalty (but there are many good reasons that you
shouldn't implement SingleThreadModel -- basically, it's misleading,
and doesn't necessarily guarantee thread safety, and it's not a clean
solution -- best is to design your servlet to be thread safe, adding
synchronization where needed -- this has been discussed extensively on
sun's servlet-interest mailing list).

  before
  
  I'm running Tomcat 3.2.1, Apache 1.3.12, java 1.2.2 and Redhat 6.2.
  
  I have a servlet to which I want to pass a single parameter via the web.xml
  file (below). I'm obtaining the parameter value by calling
  config.getInitParameter() in the init method of the servlet.
  
  This seems to work fine, the init method is called and the value obtained
 OK
  when Tomcat is started.
  
  The problem is that when the first request for the servlet arrives, the
 init
  method is run A SECOND TIME. This time the init parameter IS NOT AVAILABLE.
  
  My theory is that Tomcat calls the init method once for each thread, but if
  that is true, I would expect Tomcat to pass the init parameters each time?
  
  What is wrong?
 
 How are you calling the servlet?  I.e., via what URL?
 
 Note that you can have different servlet definitions (servlet-name)
 for the same servlet (i.e. servlet-class), and they are considered
 different "instances", such that multiple instances of the servlet
 class will be created (meaning init() will be called multiple times),
 and only the parameters specified for each definition will be
 available to that instance.  It looks like you only have one servlet
 definition, but still, if you call the servlet via the class name
 directly, it will create a separate instance.  E.g., from what you
 have below, if you call /servlet/MyServlet and
 /servlet/no.fellesdata.MyServlet, two separate instances will be
 created.
 
 
  BTW, I can't get the servlet-mapping to work either. Any obvious errors?
 
 What exact URLs are you trying?  What happens when you try them?
 Perhaps you haven't specified the appropriate directives in your
 apache/tomcat conf file to tell apache to pass it to tomcat for that
 URL.

  Ok, it's a bug. Fixing it now :)
 Is there a reason for Tomcat to use a 302 redirect? I think it would be
 better to rewrite the request internally, as other servers (i.e. Apache)
 do.
 Does the user really need to see what file actually answered the
 request?

No, but in the general case we have to do a HTTP redirect because the
servlet API allows welcome files like foo/index.html, in which case :
- the links would be broken
- the security constraints would be ignored

Eventually, we could add something smarter (which would look if the welcome
file is in the same directory), but I'll save that for the next release.

RE: oracle JDBC doesn't work

[George McKInney]

I think that (not being a DB guru):
   Connection  con = 
 DriverManager.getConnection("jdbc:oracle:thin:storedb",
 "username", "password");
   }

should be more like:

...
DriverManager.getConnection("jdbc:oracle:thin:@storedb",
...

note the '@' between "thin:" and "storedb" (and the colon is necessary)

Our setup uses (though the format above may work for you):

"jdbc:oracle:thin:@abc.def.com:1521:SID"

where:
abc.def.com is the machine name
1521 is the port to connect to
SID is the database identifier.

Hope this helps.

RE: running tomcat on Visual age

[Kirill Vasiliev]

Hi!

Did you import _resources_ (org.apache.tomcat.resources) too? They
aren't classes, they are .properties and .dtd.
This may be done in import window in VA. You also need to copy "conf"
directory from Tomcat installation to
VA_install_dir/ide/project_resources/name_of_Tomcat_project. You
also need to setup property "tomcat.home" for Tomcat project in VA -
this may be done by right click on org.apache.tomcat.startup.Tomcat
class, select Properties - the Properties window appears. Select Program
tab, in "Properties" textarea enter:
tomcat.home=VA_install_dir/ide/project_resources/name_of_Tomcat_proje
ct. Note that path must be whithout quotes even it contains spaces.
Next you'll need some classpath tuning in same window on Class Path tab.

I did it all and I have Tomcat 3.2.1 working in VA 3.5. Next my step
will be Tomcat's JSP compiling within VA...

Re: Possible bug: welcome files and parameters

[S. Schmidt]

  That way the image data gets corrupted. Isn't this information supposed
  to be in the HTTP Headers, and not in my output?
 
 This corruption is produced by an HTTP/1.1 transfer encoding called
 chunking. Its support is mandatory in HTTP/1.1. Which HTTP client are you
 using ?
 If you're directly talking on the socket or using a client without real
 support for HTTP/1.1, you may want to make a request using HTTP/1.0 (which
 doesn't have chunking), or set the content length of the response (in which
 case chunking will not be used).

I'm using Netscape 4.76 and Konqueror 2.1, and I tried Mozilla Seamonkey
on Windows. They all don't display the images correctly, and when I save
them to disk the files contain these "chunking" lines at start.

I also tried to set the content length, as you said, but that didn't
help: This is what's in the file before the jpeg data when I save it to
disk:
--- snip ---
HTTP/1.1 200 OK
Content-Type: image/jpeg
 
Content-Length: 108381
Date: Fri, 23 Mar 2001 17:44:30 GMT
Server: Apache Tomcat/4.0-b1 (HTTP/1.1 Connector)
--- snap ---
 

My code looks like this now (it worked with Resin, so I think it is all
right):
--- snip ---
// now, did we get the data? if yes, copy it
// to the response:
if ((blob != null)  (contentType != null)) {

response.setContentType (contentType);
response.setContentLength ((int) blob.length ());

ServletOutputStream out = 
response.getOutputStream ();

byte b[];
long toRead = blob.length ();
long read = 0;
while (toRead  0) {
b = blob.getBytes (read, 
(toRead  1024) ? 1024 : (int)toRead);
toRead -= b.length;
read += b.length;
out.write (b);
}

out.flush ();
out.close ();

  Has anyone else had this problem? because it
 appears as
  though I am having it too.  I have search my
 archive of
  Tomcat-User posts and the web for information on
 Tomcat
  hanging under linux SMP.  I found the above post
 but no
  replies to it.
 
  I have successfully installed the webapp I have to
 three
  different single processor computers but the one I
 want it
  on is multi proc and does not want to work.  I
 have been
  working with Tomcat 3.1 on all of the single proc
 boxes and
  initially used 3.1 on the multi proc.  The
 application was
  able to function just as it had on the other boxes
 but
  within a few minutes the application had hung and
 was not
  responding to jsp or servlet requests.  When the
 application
  got to this state though the Tomcat program was
 unable to
  stop itself, so I had to start killing processes.
 
  I then figured that possibly it was 3.1 that had a
 problem,
  so I went and got Tomcat 3.2.1.  However, this was
 pretty
  much a step backward, because with 3.2.1 the
 webapp is never
  able to work.  What's worse is that running the
 Tomcat
  shutdown script, even immediately after running
 the startup
  script, Tomcat is unable to stop itself.
 
  I can't say that I have much experience with
 Tomcat 3.2.1,
  however the mod_jk.log file indicates that it is
 finding a
  worker and the web browser accessing the webapp
 spins until
  apache times out.  I am confident that Apache is
 configured
  properly.
 
  The box's environ is
  3 * p-pro/200 + 256Mb

Tomcat and Jsp files

[Chris Andreou]

Hi I am using Tomcat 3.2.1 and Apache on an Nt platform. My confusion is
this: 
In http.conf file I have :

JkMount /*.jsp ajp12
JkMount /servlet/* ajp12

Should all the .jsp files be under the webapps directory? I have a jsp file
under my webroot Apache directory but Tomcat does not see it?

I think that (not being a DB guru):
   Connection  con = 
 DriverManager.getConnection("jdbc:oracle:thin:storedb",
 "username", "password");
   }

should be more like:

...
DriverManager.getConnection("jdbc:oracle:thin:@storedb",
...

note the '@' between "thin:" and "storedb" (and the colon is necessary)

Our setup uses (though the format above may work for you):

"jdbc:oracle:thin:@abc.def.com:1521:SID"

where:
abc.def.com is the machine name
1521 is the port to connect to
SID is the database identifier.

Hope this helps.

Hi all,

I have successfully installed the following on Solaris 2.6

I also need to implement this on HPUX and on AIX.

Will the components above ALL run on HP and AIX? More specifically, when

apxs -o mod_jk.so -DSOLARIS -I../jk -I/usr...etc

so what switch needs to be passed for HP and AIX?

RE: Compatibility with different flavors of UNIX

[Mike Braden]

mod_jk in TC3.2 has most of the build stuff for Linux, Win, and sort of
Solaris.
The scripts are not written for easy support of multiple platforms.

You may want to look at TC3.3m2 or get the mod_jk from the TC3.3 nightly
builds.

Much has been added for better support of mod_jk in TC3.3, including new
build
files and instructions for HP-UX.

mod_jk is not dependent on the version of TC that you are running, so you
can
build the mod_jk that comes with TC3.3m2 and use it on TC3.2.

mod_jk is improving and will continue to do so.

Mike.

Problem running jsp files

[MARobertson]

I'm running JBoss with embedded Tomcat on NT 4.0.  I'm having a problem
running the sample jsp's provided with Tomcat.  When I try to select one,
the response that comes back indicates an exception(
java.lang.NoClassDefFoundError: sun/tools/javac/Main ) was thrown.  My
first thought was that the classpath was not correct.  I determined that I
needed to have tools.jar in the class path.  In order to make sure that
happened, I created a batch file with these commands:

set classpath=%classpath%;f:\jdk1.3\lib\tools.jar;
cd \jboss-tomcat-2.1-beta\jboss-2.1\bin
java -jar run.jar

Yet when I attempt to access a jsp, here's what I get in the jasper.log:

2001-03-23 01:41:01 - JspEngine -- /jsp/num/numguess.jsp
2001-03-23 01:41:01 - ServletPath: /jsp/num/numguess.jsp

When I try to get to the class from the command prompt after ending JBoss,
with:
java sun.tools.javac.Main
It works, I get the java compiler started with no parms.  It seems like
Tomcat is getting the classpath from somewhere else, but I can't figure out
where!

Session doesn't work with IIS/Tomcat

Hello,
I still have the problem to make IIS 5.0/Tomcat 3.2.1 passing session
variables. Even I can't pass the form input to next page. I guess something
wrong with my settings, but I don't know where it is. I tried following:

1. I tried to use two simple jsp pages to pass session variables. it didn't
work.
2. I tried to use a bean. But scope of application worked and scope of
session didn't work.
3. I tried to accept the input from previous page using request object and
didn't work.

Then what is wrong?

Re: Running my first servlet...doesn't display

Joel,
It may have been my mail server - I'm having lots of problems with newsgroup
submissions
I recently ended up submitting the same request twice because my mail
server reported a "Couldn't deliver" message
when it actually did.
bummer.
glad you got it working on your own! The port # hasn't got anything
to do with the servlet spec. It's to do with the
configured port number of your container. Normally a web-server is
listening on port 80, and your browser will,
by default actually translate http:localhost/... to http:/localhost:80.
Of course it doesn't /actually/ change the request, just tries to talk
to a server on that port.
You can change that behavior by altering port parameter of the HttpConnectionHandler
Connector
in server.xml e.g. in the following example I've changed it to 80.

 !-- Normal HTTP -->
 Connector className="org.apache.tomcat.service.PoolTcpConnector">

Parameter name="handler"

value="org.apache.tomcat.service.http.HttpConnectionHandler"/>

Parameter name="port"

value="80"/>
 /Connector>
Now, provided that you haven't got a web server (e.g. Apache, IIS, Personal
Webserver whatever) listening on that
port, you can now just use your original URL to get to the web-container.
-Thom
p.s. If you have for a web server, then you'll get a 'port already in
use' error or somesuch.

Re: AW: java.lang.OutOfMemoryError

[brian luk]

Hi,
there is no session for each client. It's only HTTP
POST request/response, then it's over. 

--- Ralph Einfeldt [EMAIL PROTECTED]
wrote:
 Are you working with cookies or url rewriting?
 
 You have to keep some facts in mind:
   - each session needs some memory
   - each session will be alive some time after the
 last
 request to the session (default: 30 Minutes)
   - each request without a cookie or an encoded Url
 that
 matches an active session will create a new
 session.
   - It's quite easy to create memory leaks
 (especialy with a database)
 
 So your memory requirement is something like
   ("number of sessions created per minute" * 
   "session timeout in minutes" * 
   "memory usage per session") +
   ("number of requests" * "leaked bytes per
 request")
 
 Maybe increasing the heap size for the VM may help.
 Maybe decreasing the session timeout helps you to
 find
 out where your problems are.

Transparent restarts

[Jan Ploski]

Hello,

At

http://jakarta.apache.org/tomcat/jakarta-tomcat/src/doc/mod_jk-howto.html

I found the following joke:

 Q. Whenever I restart Tomcat, Apache locks up!
 
 A. The Ajp13 protocol keeps an open socket between Tomcat and Apache.
When you restart Tomcat, you need to restart Apache as well. 

What use is there of replication, if you have to restart the load balancer
when one of the workers goes away?? BTW, I tried restarting Tomcat without
restarting Apache and luckily it worked fine. So what is this scary Q/A
all about?

However, this is not the primary issue I would like to query about.
What concerns me more is how to restart the servlet engine in a way
that is transparent to users. If I am injecting new code, I would like
the user to perhaps see a short delay between requests, but definitely
not an "Internal server error" message (I assume having persistent
sessions, so these are not a problem). I guess this task of delaying
a request until a servlet engine becomes ready -- instead of spitting
out an error -- should be up to mod_jk. Does anyone know whether it
can be turned on somehow or whether it would be a big deal to implement
something like that myself? I admit to have little experience with
C network programming...

With some more support from mod_jk, application upgrades could be done
even more transparently. If I have 2 Tomcat instances, I could set up
mod_jk to do load balancing and then 1) stop one instance -- mod_jk
transparently fails over to the second one 2) upgrade this now stopped
instance 3) restart it with the updated code, mod_jk starts feeding
it with requests again 4) stop the second instance -- mod_jk now fails
over to the first, already updated one 5) upgrade then restart the
second instance. A user should not notice any delay -- there is always
one instance running.

Is this setup possible now? In particular, will mod_jk transparently
fail over and will it notice the instance once it comes back after
upgrade?

Thanks in advance -
JPL

 Hi,
 
 When a client make a request to a server and a servlet get call,

That is not what really happens.  Instead, a single instance of your
servlet is called multiple times simultaneously, on multiple processing
threads.

 My question is, how many clients can a servlet handle.
 

The maximum is determined by how many threads you configure in the
container's setup configuration, and is ultimately limited by how many
threads your JDK and operating system can support.

Re: Login Servlet

[Andrew Robson]

Hi,

Tomcat has authentication via database built in which means you should be
able to accomplish everything without need to write any code.
Read http://jakarta.apache.org/tomcat/jakarta-tomcat/src/doc/JDBCRealm.howto 
Look at server.xml for the examples of setting up a JDBCRealm with various
databases. Look in the web.xml in the examples/WEB-INF dir for an example of
setting up a login form and set of protected resources. 

Note the (very good) model that tomcat uses is 
1) Allow you to define a set of protected resources (html, servlets whatever)
2) when your user attempts to access one of those resources they get redirected
to your login form
3) Succesful login - they get sent to the original page they requested
4) Unsuccessful login - they get sent to your error page.

A common mistake in using JDBCRealm is to provide a link to your login form
rather than have it invoked automatically when they try to access a protected 
resource. This won't work - on posting from the login page you'll get 
a 404. 

Let me know if you need any help with any of this

ps I'm surprised "boolean found = rs.next()" works if result set is empty.
I'd kind of expect a null pointer exception. I always do
if (rs != null  rs.next()) {
  // assign something
}
if i'm expecting a single row.


Does anyone know where I could find code for a login servlet using JDBC.
I have a login tested, it checks the database and it outputs whether the 
username and password are correct to the jsp page, but I need to use a 
servlet for redirecting the user.
Here is the code i have for the login procedure

public void applyChanges() throws Exception
{
  Statement statement = connection.createStatement();
  try{
 ResultSet rs = statement.executeQuery("SELECT * from Registration 
WHERE (Username ='"
   + theUsername
   + "' AND Password = '"
   + thePassword + "');");

 boolean found = rs.next();
 System.out.println(found);
 rs.close();
 statement.close();

 if(found == true)
 {

 System.out.println("THAT IS THE CORRECT USERNAME AN PASSWORD!!");
 //request.setAttribute ("servletName", "servletToJsp");
 rs.close();
 statement.close();
 //response.sendRedirect ("/login.jsp");
 }
 else
 {
 System.out.println("YOU ARE NOT IN OUR DB :-(");
 rs.close();
 statement.close();
 }
 }
 catch (Exception e)
 {

 }

}
}

ANY help at all would be much appreciated. Thanks in advance, Mick

jsp - servlet - jsp

[Stijn Geukens]

Hi all,

I have a jsp (testservlet.jsp) in following directory:
C:\JAKARTA-TOMCAT\webapps\examples\jsp
and it contains:

FORM action="/examples/servlet/jsp.Servlet1" method=POST
INPUT TYPE="text" size=5 name=test value="pleasework"
INPUT TYPE="submit"
/FORM

and a servlet (Servlet1.class) in following directory:
C:\JAKARTA-TOMCAT\webapps\examples\WEB-INF\classes\jsp
which contains:

package jsp;

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class Servlet1 extends HttpServlet
{
public void doGet(HttpServletRequest request,
  HttpServletResponse response)
throws IOException, ServletException
{
  response.setContentType("text/html");
  PrintWriter out = response.getWriter();
  String temp = (String) request.getParameter("test");
  ...
  HttpSession userSession = request.getSession(true);
  RequestDispatcher rd =
   getServletContext().getRequestDispatcher("/jsp/testservlet.jsp");

  if (rd != null)  rd.forward(request,response);
}
}

I can go from the servlet to the jsp and also the other way if a use a 
forward in stead of a submit. If I do it like this I get error 404 (not 
found) although the path in the location-field is correct!
If anyone knows what I'm doing wrong or forgot to do please tell me,

thanks in advance  have a nice weekend,

Stijn

 Hey all u jsp types..whats up? 
 
 If u were woundering how sites use jsp files as their index page like this: 
 
 www.urtheman.com (takes u to index.jsp) 
 
 listen up. 
 
 
 1. make sure u turn off tomcat and apache 
 1a. create index.jsp like so: 
 html 
   body 
   % 
 out.println("Let me know"); 
   % 
   /body 
  /html 
 
 2. make sure u add contect like this: 
 
  Context path="" 
  docBase="location to ur jsp, html, css files on the same 
 network drive as Tomcat and Apache" 
  crossContext="false" 
  debug="0" 
  reloadable="true"  
 /Context 
 
 3. make sure u configure Apache to point to that location as well 
 4. config mod_jk.conf-auto so that Tomcat and Apache can communicate swiftly
 
 
 5. Start Tomcat 
 6. Start Apache 
 7. U can know punch in www.whatever.com (and itll take u to a index.jsp 
 file) 
 
 Lemme know if u r stuck! 
 
 software used: 
 
 WinNT4, Apache1.3 + Tomcat3.2 (as services), mod_jk (using ajpv1.3) 
 
 happy programming

limit servlet access to user

[brian luk]

Hi,
I have a web application running on tomcat. there are
2 httpServlet in that web app.  how can i limit user
access to one of the httpServlet?

I read the example application in tomcat under
\tomcat\webapps\examples\jsp\security which demo form
base authentication.  I looked through all the
property files but can't find where it defines the
directory restrict access. 

OR the defualt dir is \protected on the same directory
as JSP? i really not quite sure how it works.

thanks.

Double Request received.

[Reto Badertscher]

When generating and sending a rtf file from a servlet, the browser ask for
- display from current location
- saving the document

When "display from current location" is chosen by the user, the servlet
receives a second request (that means the file will be generated a second
time), when "saving the document" no additional request is sent to the
servlet.
The following parameters are set for sending the rtf document:
  aRes.setContentType("application/rtf");
  aRes.setHeader("Content-disposition","attachement;filename =
myDocument.doc");

I appreciate any hint/idea to avoid the additional request.

Thanks in advance

Depends on the platform.  On Unix systems, 1.3.x runs as multiple
processes, while on Windows it's a single process.  My understanding is
that 2.0 will let you run either way on Unix.

Even in separate process mode, there is not a fork per process -- the
existing processes are kept around to minimize the setup cost for each
request.  There is a rich set of configuration parameters that manages how
and when the pool of existing processes can grow (or shrink).

Configuring mod_jk

[A Yang]

Hello Everyone,

I was just wondering if anyone could help make sure
I've got mod_jk configured properly.

Assuming my host name is www.myhost.com and I have a
servlet context called /tomcat.

In my httpd.conf, I have my DocumentRoot set to the
/tomcat document root (for the sake of testing). I
also have:

DirectoryIndex index.html index.jsp

In my mod_jk.conf, I have the following excerpt:

JkMount .*.jsp ajp13
JkMount /servlet/* ajp13

JkMount /tomcat/*.jsp ajp13
JkMount /tomcat/servlet/* ajp13

So, what this means is that the following work:

www.myhost.com/tomcat/index.jsp
  and 
www.myhost.com/tomcat/myservlet

I'm pretty sure that if I just specify
www.myhost.co/tomcat - then index.jsp gets picked up
automatically. Which is good.

Similarly, www.myhost.com/tomcat/something.htm works.

However, when I try something like:

www.myhost.com
  or
www.myhost.com/something.htm

I get the dreaded infinite-CPU-looping java process
because it's trying to resolve a context and is unable
to.

So, my hypothesis is that Apache is NOT serving up the
html documents, because otherwise, Tomcat via mod_jk
should never have to resolve html files.

Any insight would be appreciated.

sorry V but i'm pretty sure that it isn't necessary:

resultset.next() is a method that tries to put the pointer at the first 
element of the resultset. If succesful it returns true, else false. So
found = rs.next() works fine.

Checking for timed-out sessions

[A Yang]

Hi,

Can anyone tell me what the proper convention for
checking for invalidated sessions is? Do people really
write code checking for whether the session is valid
EVERY time they are about to refer to one? And if so,
do they just examine the LastAccessedTime and create a
new session accordingly?

If this is the case, then you'd think that part of the
base class functionality would be a method that
automatically compares it to the MaxInactiveInterval -
instead of making me subclass HttpSession myself8)

Also, is the behaviour of a timed-out session defined
if I try to access one? Does Tomcat automatically
invalidate the session after it exceeds the
session-timeout value?

Thanks,
