RE: Tomcat auth problem

2005-03-10 Thread Ramu, Vinod

I would try with using extension URL mapping. For instance, 
url-pattern*.jsp/url-pattern in my web.xml. 
 
And based on the URL sent by you and I thing the application root web context 
is nbpapps. If this is true, then begin your URL under the url-pattern tag 
with faces (based on the URL sent by you) because that seem to be a public 
directory directly under your web context.

Subject: Tomcat auth problem



Hi ,

 I am facing a very peculiar problem..I have configured my web-app to
use form-based auth and it is working fine, except when I give the
complete URL of a JSP pafe inside a restricted area, it allows me
access without redirecting to the login page.

I have in my web.xml something like..

security-constraint
   display-nameagentHome/display-name
   web-resource-collection
   web-resource-nameagentHome/web-resource-name
   descriptionAgent Home Applicaiton/description
   url-pattern
   /index.jsp/url-pattern
   url-pattern/agentHome/*/url-pattern
   url-pattern/lob/*/url-pattern
   url-pattern/lob/term/*/url-pattern
   http-method
   GET/http-method
   http-method
   POST/http-method
   /web-resource-collection
   auth-constraint
   description/description
   role-nameappAgentHome/role-name
   /auth-constraint
   /security-constraint

But when i type the URL http://localhost:8080/nbpapps/faces/lob/term/ABC.jsp
it takes me directly to the page.
But on one machine in the network, it behaves OK and redirects me to
the login page...

Any idea what the problem could be?

Regards,

Kannan

Cannot compile class in WEB-INF/classes

2005-03-10 Thread Rahul Joshi

I have a Simple JSP page in my webapps/myappname. I
have a utility class which this page will use. The
class file for this should be in
webapps/myappname/WEB-INF/classes. So I put the java
source file in that directory
(webapps/myappname/WEB-INF/classes). Also, a method in
this utility class has HttpServletRequest request as
an argument. This will be passed when this method is
called from the scriplet java code from the JSP page. 

The Problem is that the utility java file does not
compile and gives error- Cannot recognize
HttpServletRequest. Shouldn't servlet-api.jar be
automatically visible?

I am using latest Tomcat 5.5.8 and latest JDK/JRE 1.5.
I can avoid the issue by not passing the request
object but still is there a way to pass the request
object?

Thanks!
Rahul.

Connection pooling verse one connection per session

Hi, I have a sort of theoretical question.  I'm
wondering about the pros and cons of using a one
connection per tomcat session strategy for connecting
to a Postgresql server rather than connection pooling.
 

My users generally login in the morning and keep my
app open for extended periods of time, usually
serveral hours at least.  The one connection per
session method seems to work well.  Here are the
reasons I'm using it.

1.  Can cache prepared statements, something that is
more problematic to do with a generic connection pool.

2.  Have better control of connection releases via the
finalize() method in a session helper class that
contains the one single connection.

3.  Easier to code and implement than connection
pooling.

4.  Potentially faster than connection pooling because
of only one connection open per session.  

Are there issues that I'm overlooking?  If I had more
users with shorter sessions, would it make a
difference?


Thanks.

RE: Cannot compile class in WEB-INF/classes

Have you compiled the class previously?  The source for the class does
not go in the WEB-INF/classes directory - only the class files go
here.  You also need to pre-compile your classes - Tomcat doesn't do

RE: Cannot compile class in WEB-INF/classes

I did not try compiling it at an external location. I
thought I would compile it in classes and then delete
the source java file later. 

I will try your suggestion of compiling it outside of
tomcat and then copying the class in the classes
directory. But does it mean that a java file cannot be
compiled in WEB-INF/classes if it is accessing
Tomcat's own servlet-api.jar?

RE: JDBC Realm by-passing login page using a link

It is my understanding that the JDBC realm will execute prior to any
filters or other servlets, so I wouldn't think this would be possible
unless you perform your own authentication - possibly in a filter - to
do just what you're looking for.

Hi,

Yes this is extremely common and in TC 5.0 is configured using an empty
path attribute in the Context element and in 5.5 it is done by naming
your web application as ROOT. FOr IIS to TC look up JK 1.2.8, there's
even an installer. Your mappings would be /something=ajp13 rather than
/context/something=ajp13.

 I know I can do this by creating mulitple Tomcat Instances but this is

 not very efficient on resources.

 I have done it with Mod_warp with success but need to do it on IIS and

 Is there a doc out there somewhere?

Yes this is extremely common and in TC 5.0 is configured using an empty
path attribute in the Context element and in 5.5 it is done by naming
your web application as ROOT. FOr IIS to TC look up JK 1.2.8, there's
even an installer. Your mappings would be /something=ajp13 rather than
/context/something=ajp13.

Good luck. Allistair.

 Subject: Mapping context to root of website

 Is there anyway to map a context to the root of a website.

 For instance:  http://www.test.com/context/ to

 http://www.test.com/

 I know I can do this by creating mulitple Tomcat Instances but this is

 not very efficient on resources.

 I have done it with Mod_warp with success but need to do it on IIS and

 Apache.

 Is there a doc out there somewhere?

 Thanks in advance.

Workers, workers, how do they work??

2005-03-10 Thread Klaus-F. Kaal

Hi,
I am not really sure that I understand the workers right.
I interface Apache 2.0.48 with Tomcat 5.0.28 via mod_jk.
Obviously, Apache accepts mod_jk to some extend, because, I get this in 
the _mo_jk.log_:

[Thu Mar 10 20:05:21 2005]  [jk_uri_worker_map.c (459)]: Attempting to

map URI '/error/HTTP_INTERNAL_SERVER_ERROR.html.var'

I have a _mod_jk.conf_ like this:
IfModule !mod_jk.c
 LoadModule jk_module /usr/lib/apache2-prefork/mod_jk.so
/IfModule
JKOptions +ForwardKeySize +ForwardURICompat +ForwardDirectories
JkWorkersFile /etc/apache2/workers2.properties
JkLogFile /usr/tomcat/logs/mod_jk.log
JkLogLevel debug
JkMount /jsp-examples/* worker1
and the _workers2.properties_ reads like this:
worker.list = worker1
[channel.socket:localhost:8009]
[ajp13:localhost:8009]
channel=channel.socket:localhost:8009
[uri:/jsp-examples/*]
worker1=ajp13.localhost:8009
In my understanding, it found worker1 which matched the request, but 
then did not really find the final context. Can somebody explain to me 
what is wrong here?

Thanks for your help.

Access Threads informations/state

2005-03-10 Thread David Causse

Hi,
I store my jdbc connections inside the user session, and I create thanks 
to a Filter one connection per thread (cause we encountered multithread 
issues with the oracle JDBC driver, and we use frames).

When the user hit the Home link I have to clean all the session 
attributes, but I don't want to clean the Connections if they are in use.
In normal condition and in a perfect world no Connection should be 
present in the session when home is called, but it is a very big app...
The session attribute name is like 
Connection+Thread.currentThread().getName().

So when hitting home I loop over all attributes in the session and I do 
special case for each type of class I find. So when I find a Connection 
object I first have to close() before gc.
I know wich Thread generated this Connection (I can easely extract the 
Thread name) and I would like to close it *only if I'm sure that this 
Thread is not serving something*.

This case should happen because there is some big db extraction that the 
user can open inside a sort of popup and continue working on the main 
app screen waiting for the export to finish.

I identified 3 solutions to solve my problem :
- Do not close a java.sql.Connection if there is still open Statement on 
it - I don't know how to do.
- Ask tomcat if the thread is serving a request - I don't know how to do.
- Never close Connection - I don't like this one...

We use :
- JAVA 1.4
- Tomcat 5
- Oracle 9i with jdbc thin driver with our own connection pool management.
Thank you for you help.
David.

Is there a way to refactor your app, to move the thread-safety outside
of the Connection objects?   Put another way, it sounds as though you
could insert a data layer between the Filter / Session objects and the
Connection objects.

The problem you may run into, long-term, is that a Java webapp isn't
supposed to rely on container-specific features, especially something as
low-level as the thread model.  


I don't see a quick solution to this.  Just about anything you find
right now will be a short-term holdover, and will eventually bite you
down the line.  If at all possible, consider refactoring the data access
of your app such that this isn't an issue.

Re: Connection pooling verse one connection per session

OK, I see your points and they are well taken.  A lot
of my concern has to do with this 

http://jakarta.apache.org/tomcat/tomcat-5.5-doc/printer/jndi-datasource-examples-howto.html#Database%20Connection%20Pool%20(DBCP)%20Configurations

There is one problem with connection pooling. A web
application has to explicetely close ResultSet's,
Statement's, and Connection's.

So I don't close my result sets, etc.  I have say 5
unique connection hits per page.  Say the tomcat
connection trash collector (set with
removeAbandoned=true) runs every 1 minute.  In one
minute a user can easily hit 5 pages.  That's 25
connections I've created and used for that user
instead of just 1.  

Am I wrong about this?  

A lot of my confusion has to do with the details of
how the underlying connection pool code works and how
efficient it is.  For instance can you assume that the
overhead to create a Pooled Connection based an an
already established connection is negligable? 
Releasing it the same thing?  There are threading
issues involved with connection pools.  Do they create
inefficient blocking conditions?

I understand that there are problems associated with
hanging onto a resource like a connection for extended
periods of time.  It's sort of a non-standard thing to
do and maybe not worth any potential cpu/memory
benefits.  I think I'm probably trying to talk myself
into droping my strategy and implementing connection
pools.

Thanks.

It looks like you're trying to use a mod_jk2 config file format with 
mod_jk.  You want a file (better called workers.properties) w/the 
following:

workers.tomcat_home= [insert CATALINA_BASE here]
workers.java_home= [insert JAVAHOME here]

worker.loadbalancer.type=lb
worker.loadbalancer.balanced_workers=worker1
(You can tweak the load balancing lines.)
Also, make sure the JkWorkersFile in httpd.conf occurs outside of any

Connection cleanup maintenance is straightforward: liberally sprinlke
finally{} blocks around data access code. -and if that's abstracted out
into a layer, and a separate set of objects, you shouldn't have to look
in that many places to insert said finally{} blocks.

: For instance can you assume that the
: overhead to create a Pooled Connection based an an
: already established connection is negligable?

A pooled connection usually *is* an established connection. The idea of
pooling (any sort of object pooling) is that the app (here, Tomcat)
instantiates some number of said objects ahead of time, such that
they're ready to use when needed. In some cases the objects are created
on-demand but then kept around for future use.

Pooled Connection objects are wrapped in another object (that also
implements Connection) that intercepts close() calls. Instead of
actually closing the connection, it returns the object to the pool.

: There are threading
: issues involved with connection pools.

Such as...? As long as you treat a Connection as a hot potato -- hold
on to it only as long as you need, then pitch it -- there should be no
such threading issues. -and as long as you only fetch Connection objects
from the DataSource, then you should never run into an issue where two
sections of code get the same Connection.

: It's sort of a non-standard thing to
: do and maybe not worth any potential cpu/memory
: benefits. I think I'm probably trying to talk myself
: into droping my strategy and implementing connection
: pools.

For me, it's mostly a design issue. I design my apps such that I can
switch the connection source (pooled, one-off, etc) and the code is none
the wiser. It just knows, I get a Connection here, and I call close()
on it when I'm done. Whether close() really terminates a network
connection/DB session, or just returns an object to the pool, it doesn't
matter...

Re: Connection pooling verse one connection per session

I'm still not entirely sure about this issue.  The
close/=null + finally blocks make for pretty ugly and
error prone code if you ask me.

Why doesn't the connection pool encapsulate closing
anyway?  Can't it encapsulate closing into the
finalize() methods?  Are there ordering issues for
closing ResultSets, Statements, and Connections? Is
infrequent garbage collection an issue?

I'm asking about encapsulating into the finalize()
methods because I don't like the asthetics of all the
close/=null + finally statements.  I believe they make
for confusing and error prone code and would like a
way to make my own encapsulating classes.

Strange error-page behavior

2005-03-10 Thread Dustin

Hey all. Very bizzare problem here.

I am running tomcat-5.0.28. I am trying to set up
custom error pages.

I originally set up a 404 error page for testing (the
error-page elements are in the server web.xml, not in
the app's web.xml):

  error-page
error-code404/error-code
location/errors/404-SNAPSHOT.jsp/location
  /error-page

Put the jsp files in place (both in the ROOT webapp
dir and my app's war) and everything worked great.
However, as soon as I added additional error-page
elements and restarted tomcat, things broke.

  error-page
error-code404/error-code
location/errors/404-SNAPSHOT.jsp/location
  /error-page
  error-page
error-code401/error-code
location/errors/401-SNAPSHOT.jsp/location
  /error-page

Now my manager won't come up at all. A request to
http://host:8080/manager/html/list displays a blank
page. No authorization attempted.

A request to another app that uses authorization
(http://host:8080/auth-app/) pulls up the 401
Unauthorized page even though I was never prompted for
credentials.

A request to an app that has no authentication comes
up just fine.

I remove all but one of the error-page elements and
everything is back to normal.

Any ideas?

Thanks,
  Dustin

 Subject: RE: Connection pooling verse one connection per session

 if ever.??? Is that really the case?  My personal
 experience with Tomcat is that it does indeed have
 memory leak problems.

Nearly all the memory leaks I've seen have been in the apps, frequently related 
to use of static variables to hold references to various session- or 
request-related items.  The few that have actually been a Tomcat problem seem 
to get fixed fairly quickly.

 In theory, shouldn't all objects created in a web user session 
 eventually be garbage collected after the session ends?

The GC algorithms do not guarantee that any specific object will be collected.  
If minor (young generation) GCs are sufficient to keep the JVM running, a full 
(tenured generation) GC need not be performed.  Objects in the tenured 
generation may never be collected and their finalize() methods may then never 
be called - the JVM may terminate first.

 I in fact did mean the finalize() method.  Is that the
 main reason not to encapsulate close() methodology
 there because of slow garbage collection?  

I don't know that I'd characterize it as slow; the current GC algorithms try 
to do as little work as possible, so it may be a long time before the desired 
object gets collected.  Since the point at which a finalize() method is called 
is so indeterminate, its usefulness is rather limited.  (Any class with a 
finalizer method is also somewhat inefficient, since it disrupts GC - each such 
object must be collected twice - and it slows down object allocation, since 
each finalizable object has to be registered.)

The try {}, catch {}, finally {} sequence is much more robust.

Well, certainly no one's forcing you to code that way.  It's just a
fairly standard practice in Java webapps to pool DB connections and to
use try/catch/finally blocks where appropriate. ;)


: Why doesn't the connection pool encapsulate closing
: anyway?

It seems you're missing the point of the pool.  Pooled connections
remain open (logged in to the remote DB).  The close() method on the
Connection wrapper object puts the (underlying) Connection object back
in the pool so others can use it.

Maybe it does; but there's no guarantee finalizers will be called.
Besides, do you want to wait for gc to run to free up connections?

This is in the docs...  I *think* closing a Connection closes all
underlying Statement and ResultSet objects, but it's good form to just

If you're waiting for finalizers to do your cleanup work for you, yes.

RE: Connection pooling verse one connection per session

I don't know.  I have one pure Tomcat (no Apache)
server that all it does is serve about 300,000 static
files per day.  The memory usage grows and grows
unexplicably.  I run a cron job that restarts it
everyday, which I had to started running with version
5.0.something or else it would eventually run out of
memory and crash.  I haven't seen what not restarting
will do on 5.5 and the latest version of Java/Linux. 
I guess I'll try and see.

I'm going to switch to using connection pools
regardless.  I really just had some questions about
the standard way of releasing them and gc issues
regarding them which have been answered by the nice
people on this list.

Thanks.

RE: Connection pooling verse one connection per session

Sorry, just had one other question about the use of
static variables.  Can this really be a problem?  I

RE: Connection pooling verse one connection per session

 Subject: RE: Connection pooling verse one connection per session

 The memory usage grows and grows unexplicably.

Modern JVMs also try to avoid doing GC if they can.  So, if you've given the 
JVM a large amount of memory, it will use it all before attempting a GC.

Tuning of Tomcat 5.5

2005-03-10 Thread Rolf Zelder


Hi Guys

For the last couple of days I tried to find some information regarding
tuning of Tomcat 5.5  Online or as a Book but couldn't find much. Where
could I get any information about this ?

I performed following steps to tune my tomcat.

1. Gave tomcat enough memory to run efficient
2. Increased the accpetCount,min/maxProcessors as well as the compression
for the AJP Connector (see below)



System Config.

Apache + tomcat 5.5 and Jboss 3.2.7

server.xml

Connector port=8009 
 minProcessors=50 maxProcessors=500 debug=0 
 enableLookups=false redirectPort=8443 acceptCount=1000 
 compression=on connectionTimeout=10 protocol=AJP/1.3 /



Cheers

Multiple threads for one submit...how to limit?

2005-03-10 Thread Jonathan Wilson

I need some good advice:
I've got a production app running on a Redhat box that is having 
problems with the SAN which is causing all processes to slow/stall with 
heavy IO(CPU util is like 3%); the network/admin guys are working on 
that part but it's been ongoing. On two occasions during particularly 
heavy IO, TC 3.x stalls all threads while waiting for the SAN to respond 
(with file uploading/loading from SAN). Meanwhile a user is submitting a 
form, which takes too long for their taste, hits stop on the browser and 
submits again(and again...). I've got code to determine if they've 
submitted a form already, but that code doesn't get triggered till after 
the submit is actually handled by my servlet. So it may be 3/4 submits 
before the locks are finally in place...Any idea how I can lock this 
down? Isolating TC from SAN is not an option.

Thanks in advance,
JW

x509 Certificate Public key Problem - HELP

2005-03-10 Thread Sanjeev Srivastava

Hi all !

I am facing problem in displaying Public Key. When I
am pasring X509 certificate the Public Key is coming
as a very long String as as given in Format 1 below,
though it should come like as given in Format 2 below.


out.println(x509certificate.getPublicKey());

I am using Bouncy Castle API and after that only the
Public Key is coming like a long String. Please
advice. 


I tried to convert the Public key into byte array then
to String, but it is showing junk charaters. The
encoding for Publick key is ASN.1 DER but its is
giving error.

I need your advice .. Please HELP...! 

byte buf [] =
x509certificate.getPublicKey().getEncoded();
String s = new String(buf, UTF-8);
s= new String(s.getBytes(ISO8859_1), UTF-8);
out.println(s);

Re: Limiting number of login attempts

2005-03-10 Thread Bob Feretich

I did it by providing a custom JDBC realm? If you use the existing realm 
as a model, the changes are not that difficult. The server.xml file 
allows you to specify the class path of the custom realm and pass 
database column names for failed_login_count and 
last_failed_login_timestamp as parameters. I placed my custom realm in 
$CATALINA_HOME/shared/classes/ and everything worked OK.

Note that this will make your web application Tomcat dependent.

Re: Multiple threads for one submit...how to limit?

2005-03-10 Thread Woodchuck

the way i handled this is with javascript.  

on my save button i simply invoke a javascript function on the onclick
event.  it checks a javascript page-scoped flag variable to see if save
button has been clicked or not.  if it has, then i popup a message
saying the previous submit is still being processed, otherwise i set
the flag variable and call form.submit().  this works even if they
press the browser stop button and then click the save button again.

basically, i'm doing the same thing as you are, but at the client-side
instead of the server side.

maybe there is a better way to handle this problem, but it has been
effective in my production app so far in belaying impatient users...

Yes this is extremely common and in TC 5.0 is configured using an empty

Re: Mapping context to root of website

2005-03-10 Thread Parsons Technical Services

http://jakarta.apache.org/tomcat/tomcat-5.0-doc/config/host.html
Sorry for the short reply. I don't always get the luxury to go into details.
The above link will take to the host element. Each host element handles a 
URL (www.mytest.com).

What you do is copy the host element in the server.xml and paste it two time 
after the first one. Then change the default name from localhost to each of 
your URLs. Note leave the first host as localhost and deploy the app at the 
ROOT context. Then change other data such as doc path to create three 
separate unique environments or hosts.

For the second two deploy the app as the default context. This is different 
depending on the version of Tomcat.

If you type in your IP you will get the first app. If you type in the URL 
for your 2nd and 3rd you will get the corresponding app. If you point any 
other URL to your IP without setting up the virtual host element for it you 
will get your first app. That is the function of the app defined with 
localhost.

Hope this helps and as usual, I'm sure there is an error or five in there.
