Servlets are not in the same package as jsp files; at least not by default. 
"Dica" may be visible in your servlet, but not in your jsp file. In older 
versions of Tomcat (and perhaps JDeveloper) jsp files were in the "root" 
package; which is likely to be your servlet package as well.

[OT] document.createElement("textarea") how to invoke events on this

[Vijay Pawar]

Hi All,

I would be obliged if someone helps me in this.

I am dynamically creating rows in my jsp by using the dom-tree functions

To create a text field i use :-

document.createElement("");

The above code works fine and on double clicking, the the alert is invoked.

Now to create a text area using dom i use the following code :-

var td5 =   document.createElement("textarea");
td5.setAttribute("name","mytextarea");
td5.setAttribute("cols","10");
td5.setAttribute("rows","2");
td5.setAttribute("wrap","PHYSICAL");

Now i wish to add a javascript event to this text area and so i tried the
following
td5.setAttribute("ondblClick=alert('hello')");

But this does not work. Can anyone please tell me how to add javascript
events to a text area that is generated like this.

Thanking in advance,
Vijay

Re: Servlet thread safety

[Bill Barker]

If your servlet doesn't implement SingleThreadModel, then it is actually
guaranteed by the Spec that there will be exactly one instance (per-Context)
that executes the request.

Re: MBeanServer Fails - Admin Tool Won't Work

[Bill Barker]

I'm not a Windows user myself, but it looks like you are missing the JMX
jars.In your %CATALINA_HOME%\server\lib their should be either a
'mx4j-jmx.jar' or a 'jmxri.jar'.  If missing, you can grab the first from
, and the second from

Re: Accessing data files via APPLET tags in JSP pages

[Susan Hoddinott]

Thanks,

I'll try that.  The component toolkit methods and awt toolkit stuff were all
looking for X11 and there did not seem to be anything else as you are
probably aware.  It does seems strange to me that the APPLETS will read
sound and graphics files on the server but not a simple data file.

This may not work, since there may be Browsers out there, that do not sent a
referer or a forged referer String (e.g. privoxy is a proxy that can change
referers, cookies...)

This approach is better since the authentification is done on the server side
not requiring any tecnical funtionality on the clientside.

To make it this far, I had to put the j2ee.jar in Tomcat's common/lib dir, and I have 
been sure to *not* include the servlet.jar in both places--it's only in Tomcat's 
common/lib dir. Also, I have put the xerces.jar in this dir, but to no avail ...

Has anyone else encountered such errors?

RE: Having a problem with IIS and Tomcat 4.1.24 config

Excuse my ignorance, but I am not sure which file these lines belong to. Is
it the uriworkermap.properties file? What is shm.file a log file? Could I
have the file parameter point to C:\Jakarta-4.1.24\logs\shm.file since all
my log files are in that directory?

Problem with request scope example

[Julien Martin]

Hello,

I am trying to understand the use of the request scope.

I have two jsp and a bean class as follows:

***first jsp





First Page




 here
 




***second jsp
<%@ page import="paquet.Person" %>

<%
p = (Person)request.getAttribute("person");
%>


Second Page










***java bean
package paquet;
public class Person {
private int age;
private String name;
public int getAge() {
return age;
}
public String getName() {
return name;
}
public void setAge(int i) {
age = i;
}
public void setName(String string) {
name = string;
}
}


I am trying to display on jsp two the properties set in jsp one. It is not
working. Can anyone help?

Thanks in advance,

Julien.

Yeah, I realized that I should diable the directory-listing instead of
enabling it. Thanks for the website, I will play there to see if I
could get my page.

Re: Mod_jk, ssl, java, and certificates question

[Jeff Owens]

Thanks Bill,

Armed with your confirmation and some searching, I figured out that the Java
(I'm using 1.4.1) X509TrustManager class can be overridden to make it think
all certificates are ok.  I'll remove the override once I get setup with a
CA issued certificate.

Anyway, thanks again!

Re: What could be wrong if I see a list of files instead of generating the webpage

[John Turner]

You want to disable it, not enable it.  Keep in mind that Tomcat 5 is 
alpha-almost-beta.  Are you sure you want to be playing with it?  It's not 
ready for production.

Regarding directory listing and welcome files:

log level set to DEBUG for serviceRequest

[Angelov, Rossen]

Hi,

Tomcat 4.1.12 and Solaris 5.7 and JDK 1.4

Is there a way to change the log level to INFO or completely remove or
change the location of bin/serviceRequest.log?

Currently it prints out tons of lines that I don't really need in the bin
directory.
I was searching for serviceRequest in the conf directory but didn't find
anything.

Is there a way to list the actual filename in the "Save As" window ?

Howdy,
This error is different than what you got before.

Does your Dica bean have a public no-arguments constructor?

No such option exists: it would be a violation of the servlet
specification for an applet (or a browser) to directly access anything
under the WEB-INF directory.

If an applet needs a certain jar, you need to place that jar outside the
WEB-INF directory.

ClassNotFoundException and FileNotFoundException

[Robert Wray]

Question:
Is there a tag I need to place in a config file, web.xml file, or somewhere 
else to allow an applet access to use/find data/class (non-servlet) files 
in a local (non-ROOT) WEB-INF subdirectory?



Problem:
For non-servlets or servlets that have dependencies on other local 
classes/files, I am not able to locate files other than servlets specified 
in the local WEB-INF/web.xml file.
Files found in the webapps/ROOT/WEB-INF/lib and 
webapps/ROOT/WEB-INF/classes are being found and used by my server. So I am 
able to make an applet dependant on certain .jar .xml or .class files work 
if I place those files in the proper subdirectory under ROOT/WEB-INF . The 
applet will work if files are place in the same base local directory as the 
applets' .html file, but it will not work when placed in the local WEB-INF 
subdirectories.



Example:
Using: Windows2K Pro. SP3 ; Tomcat 4.1.18 ; Java 2 SDK, SE, 1.4.0
I have a file "arc.war" with a structure as follows:
META-INF/
META-INF/MANIFEST.MF
Time.html
index.html
WEB-INF/
WEB-INF/data/Time.xml
WEB-INF/lib/
WEB-INF/lib/jcommon-0.8.0.jar
WEB-INF/classes/
WEB-INF/classes/connectionServlet.class
WEB-INF/classes/arcChart.class
WEB-INF/web.xml
I place the .war file into the webapps directory and it expands on startup 
assuming it hasn't already.

index.html refers to the servlet connectionServlet returning html and 
having no dependencies. This servlet works.

Time.html containing an applet using archive="jcommon-0.8.0.jar" and 
code="arcChart"
arcChart.class uses the file Time.xml
The applet gives a java.lang.ClassNotFoundException or 
FileNotFoundException for the .jar .class and .xml files.
If I move these 3 files to the arc.war base directory or the same 
subdirectories but using webapps/ROOT as the base directory, the applet works.

From the localhost_log I get messages including:

HostConfig[localhost]: Expanding web application archive arc.war
StandardHost[localhost]: Installing web application at context path /arc 
from URL file:c:/jakarta-tomcat-4.1.18/webapps/arc
WebappLoader[/arc]: Deploying class repositories to work directory 
C:\jakarta-tomcat-4.1.18\work\Standalone\localhost\arc
WebappLoader[/arc]: Deploy class files /WEB-INF/classes to 
c:\jakarta-tomcat-4.1.18\webapps\arc\WEB-INF\classes

java.security.SecureRandom
StandardManager[/arc]: Seeding of random number generator has been completed
StandardWrapper[/arc:default]: Loading container servlet default

So I know the .jar file is being loaded without any error messages...

Redirecting directories according to domain

[Raphael]

I have tomcat 4 installed in a Windows NT server, 

There are 2 domains (www.teste1.com.br, www.teste2.com.br) pointing to my Windows NT 
Server.

I have one directory called "portal"  ( in webapps directory ) and inside this 
directory I have a file called

redirect.jsp, I need to call this file like that:

www.teste1.com.br - redirect.jsp?id=1

www.teste2.com.br - redirect.jsp?id=2

I tryed this using the Tomcat Web Server Administration Tool, but it didn´t work

thanks

Under your webapp root, you have a WEB-INF directory, which has a
classes directory, which has a euc directory, which has your bean
(Dica.class), right?  Dica.java starts with the line
package euc;
right?

You don't need to modify the environment $CLASSPATH nor the CLASSPATH in
tomcat's startup scripts.  Tomcat automatically picks up classes from
WEB-INF/lib and WEB-INF/classes for your webapp.

[OT] Re: What Oracle is best?

[Jason Bainbridge]

Oracle is an enterprise level commercial Database Management System ie. $$$ 
where MySQL is an Open Source alternative designed mainly for web application 
uses (although this may change with their partnership with SAP).  These 
DBMS's can be used within servlets and JSP's by using the appropriate JDBC 
driver.

I believe the current release of Oracle is 9iR2, if you have a requirement to 
use Oracle you would want to look into using that version but it isn't just a 
download and install type affair, there are licenses to worry about and the 
actual install can be a real pain at times.

Do you want to just use a database backend for your web application? In that 
case you're best of with MySQL or PostgresSQL depending on what sort of 
featureset you require.

Re: What Oracle is best?

[Michael Duffy]

I believe you'd just need the JDBC driver jars.  I'm
connecting to Oracle from a servlet, and that's all
I'm using.  

Installing the Oracle client SQL-Plus might be helpful
for working directly with the database tables, but
it's not necessary if someone else has already done
that for you.  

You don't need TNSNAMES or the client - just the thin
driver URL, the same way you've spelled it out in the
example you provided.

I think the most current version of Oracle is 9.2.0.1.

MySQL is another flavor of database, so you don't need
that if you have Oracle.  Each database will have its
own JDBC drivers, so you'll need to get them from the
database vendor for your version.

Just put the JDBC jars in the TOMCAT_HOME/common/lib
directory and you're good to go.

RE: Is possible to run JAX-RPC under Tomcat?

[Shapira, Yoav]

Howdy,
Tomcat is a servlet container.  It doesn't support all the web services
APIs by itself.  You can download JAX-RPC and a JAX-RPC implementation
and use them in your tomcat-served webapp by putting the relevant jars
in the WEB-INF/lib directory of your webapp.

In the future, if JAX-RPC (the API at least) becomes part of the JDK,
tomcat may provide its own implementation or (more likely) come bundled
with a JAX-RPC implementation such as the one from Axis.

MBeanServer Fails - Admin Tool Won't Work

[Michael Duffy]

I've installed Tomcat 4.1.24 using the install .exe.
I'm running Tomcat as a service on Windows 2000 using
JDK 1.4.1. 

The install was smooth, and Tomcat itself runs just
fine. I can use the manager tool without problem, and
my Web apps are running nicely. 

But I get this exception in stdout.log when I start
the service: 

Bootstrap: Service started
javax.servlet.UnavailableException: MBeanServer is not
available

The admin tool does not work.  I can bring it up and
log in, but the UI doesn't show Tomcat Server.  If I
click on Resources->Data Sources, I get an HTTP 500 in
the right frame.  From that point on, everything in
the admin tool brings back an HTTP 500 response.

I think the MBeanServer and the admin tool failures
are related.  Does anyone have any advice for me on
how to get the admin tool up and running?

Re: Urgent : Can we restrict access to a directory in tomcat

[Justin Ruthenbeck]

Without more information about the intended application, this discussion 
will continue to become more academic and less directly useful ... but, 
really, what's wrong with that?  ;)

If your app needs to serve images for non-authenticated users, but you want 
to approximate security (as if you're trying to avoid direct links to your 
images, as someone else had surmised), another option is to issue 
time-sensitive keys with your generated HTML such that your  tags look 
like:



Note that this is one step further than simply requiring the user to have a 
valid session before serving the image -- it simply makes it more difficult 
for people to get at your images, but certainly not impossible.

Anyways, some food for thought... perhaps your solution lies with a little 
of everything that people have suggested.

There is no guaranteed way to stop someone directly access a gif image

be included in the web page.
i.e. in a standard jsp/servlet response to a web request the image
request is embedded in a .  This is
going to cause a browser request directory to the directory containing

The only potential method that can catch most (but not all) of these
would be to create a separate image handling jsp/servlet, say
imageHandler.  When imageHanlder servlet recieves an image request it
can check the http-referrer header and ensure that the referrer is the
url of the page to which the images are supposed to load, i.e. is the
page containing the images in /servlet/somepage then the http-referrer
that imageHandler see should be able to checked that it is
/servlet/somepage.  Someone can circumvent this control by the Internet,
but just manually setting this header themselves (via a program or the
like) and then having access directly to the images
You would then have to update all image referrences on the somepage
servelt/jsp however to something like .

tries to directly access a non authorized URL, instead of being sent  
there by response.sendRedirect("restricted_url.html"), the browser is  
redirected to a default URL instead.

This is so users can't randomly access pages that need to be completed  
in sequence, load a bookmarked order checkout page that could be  
missing state information required to generate the page correctly, etc.  
A great solution to a common problem!

Since this is a stand-alone Filter, you might be able to extend it or  
use it as a starting point for a new filter that meets your  
requirements.

Here is the filter config as defined in web.xml.


ContextSecurityFilter
	ContextSecurityFilter
	org.ofbiz.core.control.ContextSecurityFilter
	
	  allowedPaths
	   
/control:/index.html:/index.jsp:/default.html:/ 
default.jsp:/images:/includes/maincss.css:/includes/datepicker.js
	
	errorCode403
	redirectPath/ 
control/main

Is tomcat directly support this functionality. or any other solution.

Is possible to run JAX-RPC under Tomcat?

[Vy Ho]

Is JAX-RPC supported under Tomcat (out of the box)?  Do I have to
download
some module for it?  Or I have to run a separate server (such as Sun's
J2EE or JBoss)?  Is there some documents that you can point me to?  Thank
you very much in advanced.

basic authentication error page

[Vladimer Shioshvili]

Can i define the error page for the basic authentication? amd if yes, 
where? i have tried to define error-page for code 401, but realized that i 
am using constraint on everything , thus i am guessing that error page may 
be falling under the constraint as well. (not sure about that though..)

Thus, how can i  modify HTTP Status 401 - Unauthorized to be what i want it 
to be?

PS. i am trying to define security constraint in conf/web.xml for every context

I've tried to look for the solution on the web, but didn't have any luck. 
Any help is greatly appreciated.

RE: Servlet thread safety

[Shapira, Yoav]

Howdy,
You didn't miss it.  No such guarantee exists for normal servlets.  See
the javax.servlet.SingleThreadModel interface for one approach to this
issue.

However, many people will tell you to avoid SingleThreadModel for
various reasons.  I tend to agree.  The design and implementation of
your servlets should not depend on the synchronization of their service
methods by the container.  If you have shared resources put them in
objects (often singletons) outside the servlets.

Servlet thread safety

[G. Wade Johnson]

This may be an obvious question, but is there any guarantee one way or
the other about whether there is a separate servlet object for each
concurrent request.

In other words, is there any chance that instance data would be shared
between two requests? If so, are we guaranteed if the instance data will
always be shared between two requests.

I didn't see any, but I may just have missed it.

Hi David.
This method works great. Thanks
Is there any downside to using it? Is it still considered "standard"?

The setup can be a little simpler than this.  The taglib jar can contain
the TLD for the taglib in the "META-INF" directory of the jar.  If it is
present there, you do not have to deploy the TLD separately.  In
addition, if the TLD is present there, you do not have to have the
explicit taglib map in your "web.xml" file.  In this case, your "taglib"
directive in the JSP page needs to specify the URI that is specified in
the TLD in  the taglib jar file, which is hopefully documented in the
taglib documentation (so you don't have to open the file in the jar
file).

If this is done correctly, you can skip steps 2 and 3 of this process.

RE: Why does Oracle in JSP uses multiple ports.

[Lawrence, Gabriel]

There was a config option to stop this and make oracle just use 1521
that I used a couple years back for this very purpose...

Here's a discussion about how the problem and how to get oracle to just
use a single port:

I have just learned that the thin driver uses 1521 to begin the
conversation. 
But that is just a handshake. The handshake then says - "Let's finish
the 
rest of our work on another higher port" where the higher port is a
range of 
ports.

So you need a whole range of ports open. :(

Hmmm, odd. This is *exactly* what I do pretty much. I have a
LifeCycleListener specified in the webapps//WEB-INF/web.xml like this:

  
.LifeCycleListener
  

and then in the contextInitialized method of the LifeCycleListener I do a
bunch of calls to jndiContext.lookup().

Hmm, hmmm, hmmm. You are correctly specifying the listener in web.xml?

Yep, not good to stick them in server.xml.

Your .xml file containing your resources should be in the
webapps/ directory along with your packed or unpacked application
You can then access your resources using:
 jndiContext.lookup("java:comp/env/");
Is this what you are doing? Are you using the correct Context
(java:comp/env)?
Yes, and this is my trouble: when the application is running I can 
always perform such a lookup successfully, but when I try from a 
ContextListener contextInitialized method it fails: the same code WILL 
NOT FAIL contextDestroyed !!!
I experience the same failure from the init method of a servlet

Re: Assessing Tomcat's State

[Francisco J. Bido]

Thanks for the link.   I didn't know about Nagios; it seems like a 
pretty useful tool.  I'll have to take for a spin.

About the Tomcat state issue, I actually got them resolved.  I 
basically followed Tim Funk's tips (see prior posts).
I modified some C code to get the UNIX PIDs straight from the kernel 
and handle the polling for the "shutting down" state, and
also  found some nice URL classes within the Cocoa frameworks 
(Objective-C on Mac OS X) to handle the polling
for the "starting up" state.   I'm a happy camper.

RE: Why does Oracle in JSP uses multiple ports.

[Brad Rhoads]

I originally thought that was the exact issue. If you look at the
listener.log, the "new" port# is random. In fact even the rang of numbers
appears to be different on our different servers.

In spite of this, we're getting ports 33047 & 40147 consistantly; it appears
to be somehow be a function of the sid. We have restarted Tomcat many times
now and everything is working OK. I guess we should restart the box and see
if it still works.

Any other ideas or explanations?

From memory Oracle uses JServ for something or other not sure what exactly but 
have a look in something like ORA_HOME/Apache/Jserv or just poke around your 
ORA_HOME a bit for the right configuration file, maybe just do a search for 
8080.

JNDI datasource non available in ServletContextListener.contextInitialized

[Federico Spinazzi]

Hi you all,

I'm trying to build application wide variable from a 
ServletContextListener under Tomcat 4.1.24.
Some of the variables are built with data read from a database.
I've been able to successfully define the JNDI datasources and to list 
them in the contextInitialized method
but I needed to try many possible combinations (see later) to 
succesfully perform the lookup in the contextInitialized call: it seems 
like if Tomcat doesn't make the JNDI completely available during the 
initialization sequence of the web application: infact the following 
behaviour is applicable to an init method of a servlet loaded at start-up.
I would like to share this experience and to ask for help, if I'm doing 
something wrong.

There is only a way I've managed to get the result (to be able to 
estabilish a connection using a DataSource retrieved from a JDNI lookup):
- declare the use of the resource in web.xml
- define the resource in server.xml (this is a little 'limitating' for me)
- deploy the applications in unpacked format (i.e. not from a war file: 
this is quite limiting, however)

I want to list othe options I've tried (sarting from an 'empty' webapps 
directory) without success:
- stop tomcat, copy theApplication.war and theApplication.xml in 
CATALINA_HOME/webapps: theApplication.xml contains the context 
configuration, start tomcat
- deploy theApplication.war with a META-INF/theApplication.xml  in it:
The stack traces look like this:
javax.naming.NamingException: Cannot create resource instance

RE: Servlets not working in my context: SOLVED

[Schwartz, David (CHR)]

Hi All.
I finally got it.

I was using Oracle 9i & Tomcat on port 8080.
Oracle 9i installs a service on Port 8080. This causes the logon  popup. You
either have to change tomcats port or disable the oracle feature.
I changed Tomcat port to 80.

Does anyone know how to disable or change oracle from port 8080?

Urgent: Strange Exception in my jsp file

[Jose Euclides da Silva Junior - DATAPREVRJ]

Hi gurus,
help me to solve this strange problem at my project. The rodrigo2.jsp file (
CODE BELOW ) runs fine in JDeveloper but returns an strange exception in
TomCat 4.1.18. This jsp app creates a reference to a java bean, named DICA,
which is instanced by an previous servlet. What does this message mean?
Should i configure anything else in my TomCat?
Thanks in advance,
Euclides.

Why does Oracle in JSP uses multiple ports.

[Brad Rhoads]

My client had to open port 1521 between the webserver and Oracle DB server.
This makes sense. But he also had to open port 33047 for our application
pointing to the test SID and 40147 for the copy of the app pointing to the
prod SID. Both ProdApp and TestApp are exactly the same except for the
Oracle SID.

Here's part of the log from their Check Point firewall (before they opened
up these other ports):

service sqlnet2-1521 is port 1521
service WebServer is port 40147


Number  DateTimeAction  Service Source  Destination 
Protocol
454885Jun2003   8:30:17 Accept  sqlnet2-1521WebServer   
synapse.berlinind   tcp
454895Jun2003   8:30:17 DropSynapseWeb  WebServer  
 synapse.berlinind   tcp
457085Jun2003   8:31:50 DropSynapseWeb  WebServer  
 synapse.berlinind   tcp


Every SQL request sent through one 1521 which was accepted, and 2 40147s
which were dropped.

Can anyone explain this?

RE: Hyperthreading and performance

[Shapira, Yoav]

Howdy,
I haven't gotten around to benchmarking this, although I'm curious.
It's not as much a tomcat issue as it is a general JVM performance one.
Would you be able to benchmark your system with and without
hyperthreading, and hopefully sharing the results with the list?

I realise that this is slightly a JVM dependant question but doe anyone 
have any views on using Hyperthreading on Xeon processors and whether it 
will affect performance or not?  As far as I can ascertain, hyperthreading 
essentially splits the processor into two threads internally which appear

allows for performance equivalent of a dual processor system when you only

Will this help or hinder Tomcat?  Ive heard many people saying essentially

RE: check for session

[Collins, Jim]

Hi Brian,

I mainly develop Web apps that are front ends to Documentum and all the apps
I write are JSP/Servlet based apps and I use the Struts framework to help
build these apps. I use struts to help with the apps flow control and
mapping logic and the custom tags that it provides to help with forms and
display. All Documentum specific code is wrapped in beans that my Action
classes call.

If you require any more specific details please let me know.

Hi Mark,

I use Documentum and struts and had something similar to what you now have
with a Filter determining if a user has a dmSession. I found however that on
a number of occasions when the filter was checking for dmSession it was
returning null (even though I knew it had previously been created) and the
app was recreating the session and saving it. I have now removed the filter
and written a custom tag that checks for the existence of the dmSession and
if it does not exist creates it, if there is a problem creating the
dmSession the user is redirected to an error page.

Regards

Jim.

Very possible, I was just acknowledging my lack of experience in being able

The source attribute of the IMG tag would be something like

The servlet would just retrieve the image from the WEB-INF directory, 
and spool it out as a stream.

I'm not sure on the performance, though.  High-traffic might be a

create a servlet that is mapped to your /images mount point which

RE: re. to Thomas.Rimmele( I used param tag just as u said)

[Jacob Kjome]

First, I think you mean super.init(config) and second, there is no need for 
that if you call the "init()" method rather than init(ServletConfig 
config).  See the javadoc...



public void init()
  throws ServletException
A convenience method which can be overridden so that there's no need to 
call super.init(config).

Instead of overriding init(ServletConfig), simply override this method and 
it will be called by GenericServlet.init(ServletConfig config). The 
ServletConfig object can still be retrieved via getServletConfig().

Re: Urgent : Can we restrict access to a directory in tomcat

[Jacob Kjome]

I don't know why this would be any slower than tomcat itself?  Tomcat 
serves images by loading them as a stream from the default servlet and 
returns them to the browser.  It all depends on how you implement this.  It 
very well could be faster than Tomcat itself since a servlet dedicated to 
serving images might be even faster than a Tomcat's default servlet which 
must take care of serving all kinds of files and, therefore, probably has 
more overhead.

The source attribute of the IMG tag would be something like 
/servlet/imgGetter?image=someUniqueKey.

The servlet would just retrieve the image from the WEB-INF directory, and 
spool it out as a stream.

I'm not sure on the performance, though.  High-traffic might be a problem.

Hi Mark,

I use Documentum and struts and had something similar to what you now have
with a Filter determining if a user has a dmSession. I found however that on
a number of occasions when the filter was checking for dmSession it was
returning null (even though I knew it had previously been created) and the
app was recreating the session and saving it. I have now removed the filter
and written a custom tag that checks for the existence of the dmSession and
if it does not exist creates it, if there is a problem creating the
dmSession the user is redirected to an error page.

Regards

That is the way I would do it and I've just done something similar but with 
PHP instead... 

Basically you store the images either outside the document root ie. in WEB-INF 
for Tomcat or if using Apache you can use a .htaccess to deny from all 
instead, then you have your usual security framework within your web app and 
only allow authorised users to see the images.

Although once you have served that image there is nothing you can do to stop 
people from using it, I wouldn't even waste your time looking at Javascript 
to block right clicks or anything like that, a quick disable of javascript 
gets around that one...

RE: Tomcat configuring for email

[Phillip Qin]

Tomcat has this nice feature called Resource mail/Session. Without this
feature, in your code, you get a mail session by:

Properties props = new Properties();
props.put("mail.smtp.host", "mysmtphost");
Session mailsession = Session.getDefaultInstance(props, null);

With Tomcat's jndi lookup, you can get session by:

Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
Session session = (Session) envCtx.lookup("mail/Session");

But you still need to setup the sending params, such as

Message m = new MimeMessage(session);
m.setFrom("sender");
m.addRecipient(Message.RecipientType.TO, "recipient");
m.setSentDate("date");
m.setSubject("subject");
m.setText("text");

Transport.send(m);

The other way to do it would be to check the referer page, this seems to 
be quite a common trick and will confound most people trying to link 
directly to your images (which is what I imagine you're trying to 
prevent). There may be a more elegant way of doing it, but you could 
create a servlet that is mapped to your /images mount point which 
inspects the referer field in the request and, assuming it is valid, 
returns the appropriate content from a directory outside of your web 
application. As all requests would go through the servlet you have 
access control.

RE: Urgent : Can we restrict access to a directory in tomcat

[Shapira, Yoav]

Howdy,
That one's tricky (and strange).  When you have a servlet or JSP, the
output the user sees is HTML.  In HTML, you have  tags.  The
browser will request those images normally in HTTP requests.  So from
the server's perspective, the request is the same whether the user types
in the image URL or you embed it in one of your pages.

Would something like using a mangled images directory name ($KF_%# or
something) be sufficient?  A name that's hard for users to guess and use
directly?

java.net.SocketException: Connection reset

[Mindaugas Genutis]

Hello,

I am getting the java.net.SocketException and my JSP application crashes. 
I have pasted the exception below. It comes from the catalina sockets 
engine. Does anyone have an idea where should I go further for fixing this 
socket problem?

My server configuration: Redhat Linux, Tomcat 4.1.24, Java 1.4.1

2003-06-09 12:24:38 StandardWrapperValve[default]: Servlet.service() for

RE: Off Topic: JSP that reads and creates links to file directory

[Tom Lyle]

I'd say that the String path
="../dirList.jsp?path=//\\corportateFileServer\department\team\communication
s\statusreports\monthlyConsolidatedReport&title=Team+Monthly+Status+Report"
isnt a valid file path for

File file =  new File(path)
