Re: Static class across multiple tomcats?
I think sharing a common class across servlets can get tricky... I've never tried it using Tomcats intrinsic technology, but I think if you if you want to go this way then read up on the ServletContextListener. Lets you look at what other servlets are up to, so you could make something that looks at servlet 1 and if it hasnt made the common resource then, servlet 2 will make it... then when servlet 1 starts it checks servlet 2, see's its already running and uses that mm I dont like it, think code could get very messy. What I do for for this kind stuff is use Harbor So I would make the shared class, dump it in the Harbor servlet and then call it from other servlets... Harbor is a very lite application server. I wrote Harbor and I'm keen to test it on this sort of application, so if you care to give me the test code of your shared object, I make 2 servlets and show you how to share the object across all your servlets even if they run on different machines.

If you have a problem with dB connections or you not releasing memory the handles will just keep climbing and then eventually windows will go snail on you and everything gets very very slow.

Re: Basic Auth without web.xml security-constraint not working
Ha ha... sounds like you looking for a magic function, which reminds me of
my first computer program... got to tell you :)
A million years ago in my 1st year I was walking past the varsity main
frame, I'd heard all sorts of things about this amazing beast... so I walked
in, watched someone using a punch card, after they left, I typed draw
nude girl... stuck it in the machine and was hell-of-a-disappointed when I
got syntax error ha ha.
No, I think you expecting too much the Tomcat guys have let people who
want to develop a quick servlet, define the DOORWAY to the role in web.xml
and then quickly add users to the role in tomcat-users.xml and have
provided a few simple functions like isUserInRole, which for the simplest of
web sites are not even needed.
Its simple, easy, and probably good enough for most things a tomcat
developer needs... very nice of them.
I was hoping that for what you need it would be possible to piggyback on
that simple framework, even if it meant parsing the tomcat-users.xml to gray
menu's, but it seems you have to work outside of that frame-work.
If you are writing code like the stuff below forget about the simple
security framework tomcat provides, you dont need the Doorway in web.xml,
and likewise tomcat-users.xml is not going to do a thing it only wakes
up if you do the web.xml stuff. So if you define the URL and the restraining
role in web.xml, then tomcat wakes up and looks at tomcat-users.xml. If not,
it doesnt know you doing security, and even if you write security code, it
only between you and the browser, Tomcat will just send what you tell it to
and get a browser response back.
If you writing code at this level forget about that config stuff.
you on your own.
Cant quite see how you would use JAAS, but ok you going to use Ldap or
something.
No magic functions you have to do something like this...
Using your code below, you make a servlet, and map all the urls through it.
A request comes in
You grap the user name and password...
You call ldap or JAAS or whatever security system you using
It tells you User OK, or NOT
If OK you DISPATCH the request off to the JSP page and it displays.
If you want to control menu's you ask the LDAP system or whatever if user is
allowed access to various menu items (which represents other roles).
You stick that in a Bean pass it to the JSP page, it enables or disables
the menu's, and displays.
Not hard to do if you know tomcat
Somewhere and somehow you have to be able to tell the system all the users
and roles...
Whether you get it from JAAS or LDAP or parse the tomcat-users.xml,
somewhere someone has to be able to tell the system, USERA is in
RoleAccessPage1,23.
In fact I'm beginning to think that what you looking for is yet another
mapping...
So for example you may have a generic roles like, Visitors, Admin, Managers,
New Employees, Company Visitors blah blah...
And then have another XML file that says
ADMIN - ALL PAGES
VISTORS - Intro.jsp, Welcome.jsp,Instructions.jsp,How To Pay and access
the good stuff.jsp
I still have a feeling all you really need is the generic tomcat security
and someone to write a little XMLparsing code that gives you functions like
IsThisUserAllowedToAccesThisPage(User,Link);
Then you have Two Maps to fill out User - Role (already standard in
tomcat)
Role - Link (a
new XML file)
MaybeAnyway I dont think you going to find the magic function you
looking for, and I also dont think its an oversight by the tomcat
developers, just think you looking for an additional mapping function. Maybe
it would be nice if Tomcat had a function to enumerates user roles (has it?)
but even then you'd still be making some additional mapping function...
If you need someone to write the framework for you, once you have decided
what you want, call me.

Johnny

Re: Basic Auth without web.xml security-constraint not working
Hi Tony,
Mmmm, kinda understand what you saying something like this, Tomcat wants
to check the users at the FRONT DOOR, and either kick them back onto the
street or let them in, but you want to let them ALL in and let some use the
dining room and some use the kitchen you trying to be polite and put a
NO ENTRY on the bathroom door before the user even tries. Interesting
To trigger the built in Authentication you have to make the users all part
of a ComeInAndLookAround ROLE, but now everyone can get through any door, so
you need to check the additional roles yourself to determine access that
really defeats tomcats security, thus the problem I dont like this.
OR you need to leave the generic security alone, ie you have
Page1AccessRole, Page2AccessRole, so that normal humans can administer the
roles as Tomcat intended, and on each menu Item have
IsUserAllowedToAccessPageX, if not grey it, else show it. In this case you
would need to parse tomcat-users.xml which has the format like this user
username=admin password= roles=admin,manager/ and it not difficult to
find the roles for a user. Just some XML parsing I would go this way,
because its in the expertise of the Tomcat Admin guy or girl.
OR you could do the above but with your own internal logic, so you protect
access to pages with tomcat and then maybe have a separate file that lists
users and menu access allowed... in which case you need to make your own
config file, dB would work well. could be the right way depending on
what you making.
OR you could decide FRONT DOOR checks are not for you and do it all
yourself, in which case this code will get you going
Getting the user name and password
String authorization = request.getHeader(Authorization);
if (authorization == null) return 0;
// Authorization headers looks like Basic blahblah,
// where blahblah is the base64 encoded username and
// password. We want the part after Basic .
String userInfo = authorization.substring(6).trim();
BASE64Decoder decoder = new BASE64Decoder();
String nameAndPassword = ;
try{
nameAndPassword = new
String(decoder.decodeBuffer(userInfo));
}catch ( IOException e ){}
// Decoded part looks like username:password.
int index = nameAndPassword.indexOf(:);
String user = nameAndPassword.substring(0, index);
user = user.trim();
if(user == null) return 0;
String password = nameAndPassword.substring(index+1);
password = password.trim();
if(password == null) return 0;
To trigger the browser the headers look like this
response.setStatus(response.SC_UNAUTHORIZED);
response.setHeader(WWW-Authenticate, BASIC
realm=\User Check\);
The coding is a hassel, but you have a lot of control like Ok You Not
Allowed In Here normally, but I'll let you in and grey all the menu's
I'm not sure what it is you trying to do, hope this gets you going...

Johnny

Subject: Basic Auth without web.xml security-constraint not working
Tomcat seems to only check the Authorization: headers if there is some
security-constraint explicitly declared in web.xml. However, it
appears that the optimization has been incorrectly implemented because
it does not then recheck the header if request.isUserInRole(...) etc.
are called. So users cannot log into a system that uses
request.isUserInRole(...).
More specifically,
my simple application tests request.isUserInRole(...) and
request.getRemoteUser(). If the user lacks permissions the application
sends a 401, and the user is prompted for a name/password which is sent
back as a Authorization: Basic dGltOlBhc3N3b3JkMQ==
So far so good. But Tomcat then ignores the Authorization: header which
is correctly sent by the browser.
The web.xml has
login-config
auth-methodBASIC/auth-method
realm-nameAgile UI: tim/Password1/realm-name
/login-config
in it.
There is no security-constraint clause in the web.xml because I do not
want to declare them there. (They are instead declared internally as
part of a menuing system, which calls request.isUserInRole().)
A hack to make Tomcat look at the Authorization: header is to add the
following to web.xml
security-constraint
web-resource-collection
web-resource-namedbtest/web-resource-name
url-pattern/dbtest/*/url-pattern
/web-resource-collection
auth-constraint
role-namedummyrole-name
/auth-constraint
/security-constraint
In which case it works if one accepts the unwanted dummy query.
Is it possible to tell Tomcat to always check the Authorization:?

Subject: Service instance serialization question
Hi,
I have a web service which is running under the Tomcat container. Tomcat
creates a new instance of
this web service with each incoming simultaneous connection. The problem I
am having, is that my web service
calls a hardware device which can only handle one query at a time. If I
have 5 instances of my web service
all querying it at the same time, it hangs. I need to implement some sort
of serialization such that only one
request is processed from each instance at a time. Is it possible to
serialize between service instances, which
have been created by tomcat? Is there some external library to tomcat
shared memory object which will
allow me to do this? I have had a look around the web, but I'm not really
sure where to start. I've come
across messaging solutions, but all these seem to be targeted towards
serialization between services located
on completely different tomcat instances (JMS).

Hi Peter, I probably got the wrong end of the stick, missed the thread etc, but its seems like you going through a whole lot of pain so I was wondering. If you have a servlet and a bunch of JSP pages, did you know that the JSP's will not compile when you Clean and Build in Netbeans. If you right click on the project name and under the compile section ask it to--- then it will. Or if you compile each JSP file then it will to. So its possible that its just an error in the JSP that goes undetected until the browser hit it. Try set it up so that it compiles all the JSP's and I have a feeeling you will see it at design time.

Re: JSP page not updated on each request
Mmmm, dont know I think the browser should be picking up file changes, but if you want to make sure the browser doesnt cache, then if I remember correctly search for NO-CACHE and set the headers returned, the browser will reload every time. Note that headers are different for different browsers so you have to set a few headers... google will tell you. Note that when you developing, I've noticed if you leave the browser open, it may still display previous page... but it doesnt happen once deployed. Other thing that maybe catching you is that you changing something in the servlet INIT routine... and that somehow impacts on your JSP pages say thru a bean. That wont reflect until you stop and start tomcat..INIT runs once at start up. good luck - Original Message - From: pkumar [EMAIL PROTECTED] To: users@tomcat.apache.org Sent: Thursday, March 15, 2007 9:39 AM Subject: JSP page not updated on each request Hello, The JSP pages in my project is not showing the updated one upon each request..Its showing the old one and only when i press the refresh, its showing the updated one...I believe this is the problem with Tomcat..Can someone help.

Re: how to configure the tomcat to automatically update class instances when a class file changed
Hello again SANGAMESHWAR In the servlet.xml config file you will see the Host name=localhost appBase=webapps unpackWARs=true autoDeploy=true The autoDeploy=true means the sevlet will reload if anything is changed under WEB-INF So if you drop another library class in, or say change web.xml, that servlet will restart WHEN IT IS IDLE. If you have a thread running in a background process, then I dont think it will ever restart. Its clever but it does mean Tomcat has to rev up all over again and on a busy server thats probably not a good thing. Other alternative is to make a plugin, and load up the classes yourself... maybe able to find a standard one, if writing a classloader seems like too much work. Or you can try my software HARBOR at http://coolese.100free.com/ it allows you to control the reloading of classes.

Re: How does one configure Plain host domain url to run web app?
Hi John,
Ok, I'm going to try show you how I think about this stuff... and I'm often
wrong ;)
Dont use a redirect... it goes back to the browser and its not cool.
Firstly make a servlet and have a look at the CONTEXT.XML file under
META-INF
Change it to..
?xml version=1.0 encoding=UTF-8?
Context path=/
Now have a look at WEB.XML under WEB-INF
make sure the mapping is
servlet-mapping
servlet-nameNewServlet/servlet-name
url-pattern/*/url-pattern
/servlet-mapping
OK now that servlet will run for any URI from the domain name up ie
www.host.com/ANYTHINGorNOTHING
You can play with the mapping if you dont want that... but let me show you
how I do this sort of stuff, and then you can tweak it as you want.
Now in the servlet make this routine
protected void displayPage(HttpServletRequest request,
HttpServletResponse response, String thePage)
throws ServletException, IOException {
RequestDispatcher dispatch =
request.getRequestDispatcher(thePage);
dispatch.forward(request, response);
}
Now when the servlet is called in
protected void processRequest(HttpServletRequest request,
HttpServletResponse response)
do this
displayPage( request, response, index.jsp);
So all of a sudden you can direct any URL to any page without redirects
can use the API to check the URL and use a case statement whatever.
OK... heres the final trick coz it looks like you trying to run behind
Apache
put this in the servlet.xml file in Tomcat.conf
Host name=www.site.com appBase=webapps
unpackWARs=true autoDeploy=true
xmlValidation=false xmlNamespaceAware=false
!-- USE THIS FOR AUTO GEN OF JK MOD for Apache Forwarding to tomcat
MODIFY PATHS FOR YOUR SYSTEM--
Listener className=org.apache.jk.config.ApacheConfig append=true
forwardAll=false modJk=D:/DEV/Apache2.2/modules/mod_jk.so/
/Host
Now when you start Tomcat it will create a folder under conf/auto it puts
all the stuff apache needs in a mod_jk.file
looks like this but its AUTOMATICALLY generated when tomcat starts.

Re: File Content Not Saved To Server
Its been a really long time since I played with Applets, but if I remember
correctly I think you screwed. I dont think an applet container will let you
access a local file system and send it to a server, it would create huge
security holes. So even if you get the code right, browser will start
outputtung security exceptions if I understand correctly, cant actually
make out how you accessing the local file.
I think you gonna have to use a file uploader... theres one on the apache
site.
My general comment is that in general Java Applets are dead microsoft
saw to that.
If the user has Java on their machine and you really really have to have a
Swing type app then another way is to
maybe use http://coolese.100free.com/
I have a free application server... easy to use, you can let them run the
Swing application FROM the server.
I think they would still have to pull a very small App from the browser, but
it will start very quick.
I think as soon as you try run any local disk access from an Applet you
outta luck.

Dear All,
I really need this program to work as soon as possible and need urgent
help! Mr. Christopher Schultz have given suggestions on how to solve the
problem and I've tried his suggestions. Thank you so much, as half of the
problem have been solved. I've created 3 files as suggested:
SaveFileApplet.java, SaveFileApplet.html and SaveFileServlet.java. This
solves the problem of the creation of a null file by the system. Now, a
file name that was input by the user was created BUT the problem is that,
when I open the file, the word null was written to the file NOT the file
content. The filename parameter was sent from the applet to the servlet
BUT the file content parameter was not sent. This means that the file
content parameter does not exist and the servlet did not receive the file
content parameter! Did I pass the file content correctly from
SaveFileApplet.java and did the SaveFileServlet receive the parameter
using req.getParameter(teditor);? I'm attaching the 3 files
(errer-free) as I mentioned. I really really hope that anyone can help me
solve this problem. Thank you so much.

Re: EJB 3.0 and Hibernate
Hi Scott, Not sure what you mean by container managed service, tomcat on its own is a servlet container, not an application container, like JBoss, maybe you saw hibernate referenced in Spring which is a whole collection of frameworks built on top of servlet technology, it uses hibernate, and has an EJB container and everything else you can think of. Spring competes with JBoss and the Sun spec. Some say the reason for EJB3 is because of Springs rapid growth and good idea's. Personally I'm thankful Tomcat hasnt tried to become a Super Can... hope it never does. I'm pretty certain that in the Hibernate manual on their site, I saw an example of how to persist in servlet technology, but remember its still not an application server, all they doing is allowing you to save a session bean to disk (dB). Hibernate is amazing technology, didnt have time to find out exactly how they do it, but I think they use reflection to pick up the get and set methods and then, insert some method probably via BCEL into the java binary class constructor, so that when the class loads it gets the data from the dB and populates the properties but thats all it really does, its not a container on its own. You can run Hibernate against any Java bean type class, doesnt have to be in Tomcat or anything, but I think if your code is something that was written for JBOSS and you trying to port it to another container... its going to be very very difficult. Probably uses all sorts of annotations that glue it to JBOSS. Anyway if you knew all this, ignore my lecture... and its not a stupid question, its seems there are pure application servers out there that consider servlet technology to be a component of the application server... think it stems from the Sun spec and JBOSS is one of them. Tomcat is just a component in JBOSS. Then there is the Spring framework which seems to have grown off the top of Servlet technology, and then there is also RESIN, which most people call a very good servlet container, but it also has an EJB container built in. So I think its becoming a grey area... Servlet technology is so powerful, I think its a natural rival to any other container out there. Just to prove the point... I wrote an Application server for Tomcat, but I must warn you that I dont like the complexity of the Super Cans, and its very very simple in comparison... means you will get it running in an hour, but if you want to use hibernate, you have to do it yourself, there are no annotations or xml glue. Can get it at http://coolese.100free.com Anyway its interesting... will the application server absorb the servlet, or will the servlet trample the stand alone application server into extinction... I think Servlets are winning and will win, which kinda creates all sorts of problems for the Sun Specs. Will probably end up as, if you want to run a bank... use JBOSS or the Sun equiv, but for everything else I think its going to be servlets. So, dont know what you doing, but dont write off Tomcat or servlets... its an absolutely amazing technology... worth a good look. If it is just a web application you trying to port, and its used some Super Can technology for persistance, I think its going to be easier to replace that. Think you'll find Tomcat a whole lot easier to learn than JBOSS. Whew!

RE: Tomcat and NetBeans IDE - THE BEST
Hi there, I also only recently started using Tomcat and Netbeans and its a match made in heaven. I use Tomcat for EVERYTHING its fantastic, wonderful, best thing I ever discovered, and Netbeans is sizzling hot as well. No, you dont have to use the embedded Tomcat server, and it wont be long before you get a later Tomcat and want to use that anyway... So what you do is open TOOLS-SERVER MANAGER and point it to the Tomcat version you want to use... its that easy. Now you do not have to worry about starting and stopping Tomcat(the new one) when developing, as soon as you start a servlet it will happen automatically. If you want to stop it, you do it from INSIDE Netbeans either in the Runtime Tag, or you will see you can do it from the Tomcat Tag in the OUTPUT section of netbeans so you develop as normal. Now when you CLEAN and BUILD your project you will see that it creates a DIST folder with the WAR file... that you simply drop into the WEPAPPS folder of ANY TOMCAT and then start THAT tomcat as a standalone (without netbeans running) and its deployed you can also use the Tomcat manager from the web browser but I find this method easier. Now just one thing that can be confusing when Netbeans does all its magic and lets your debug stuff... it actually creates a temporary BUILD folder and when you testing that is the code that is ACTUALLY running in the TOMCAT you using. Now what happens alot is that you drop your WAR file into tomcat BUT its not actiully deployed because NETBEANS still has control of Tomcat and what is actually happening is that Tomcat is still running your servlet in the BUILD folder. It doesnt pick the WAR file up. So what I do before checking a WAR in tomcat, is DELETE the projects BUILD folder. Now if Tomcat complains, thats good, because you know it was still looking at the devlopment environment. Just stop tomcat, put the WAR file in WEBAPPS and restart it, it will pick up on the new WAR. Dont give up, Netbeans and Tomcat are magic, best development environment I've ever used. If you want to see some pretty cool stuff I've developed on Tomcat go to http://coolese.100free.com/ Theres a) A replication system for POSTGRESQL b) A web site search engine based on LUCENE c) An Application Server HARBOR, that lets you run normal java apps from anywhere if you also think, JBOSS, SPRING etc are too complex. ALL DONE IN TOMCAT and NETBEANS... I love them. == Hi , I am new to tomcat and be grateful for your reply and explanation. I have downloaded NetBeans which is bundled with Tomcat server . I use tomcat from within the environment to test my pages.
Re: Specifying relative path for TOMCAT 5.5 ?
Hi Rajendra, This also confused the hell out of me. Here are some tips If a url is relative, its relative to the page eg moreInfo/Details/SomePage.htm So its going to depend on the page the user is viewing and go from there... just like normal HTML pages. When you want it to go to an absolute relative page LOOK at the folders under you project name, or the folders under Web Pages in netbeans ONLY. So in Netbeans if you have Details/SomePage.jsp under Web Pages and you want the link to go there, you would write it as /Details/SomePage.jsp That little / at the beginning makes it go to that page regardless of the page it is in. Now when you want to get at your class files, you normally just use the class name, no paths. eg: jsp:useBean scope=request id=searchBean class=com.myco.searchResultBean / BUT if you want to get at say the actual bytes then one way is to ServletContext context = getServletContext(); sWebInfPath = context.getRealPath(/WEB-INF/); This will give you that actual location on your file system and then you can just use (new File) etc to get at the physical file in the sub folder. A more advanced function is to go the same way as you would if you wanted to extract the bytes of a class from a Jar file in = getClass().getResourceAsStream(sPackageName); it also works on Tomcat. Hope that helps. Heres some free software for you http://coolese.100free.com/ All done on the amazing Tomcat - Original Message - Hi, I am using TOMCAT 5.5.
