RE: setting application variables
You could have a ContextListener for your web application. You could then read the properties from your property file and put them in the application context so that all your JSP pages have access to them. In order to implement a ContextListener you need to write a class that implements the ServletContextListener interface. You will have to make an entry in your web.xml about the same. Hope this helps, Mufaddal. -Original Message- From: Josh Howe [mailto:[EMAIL PROTECTED] Sent: Friday, July 29, 2005 1:14 PM To: tomcat-user@jakarta.apache.org Subject: setting application variables Hi, I'm very new to Tomcat and JSP.

Tomcat and SSL
Hello, I wanted to verify if I am understanding this right. The website has certain sections of it using HTTPS (secure) and certain sections use only HTTP (unsecure). 1. A new session resulting from a call to request.getSession(true) in a secure area of a website is invalidated automatically when the session transitions from the secure to an unsecure area of the website. 2. A new session resulting from a call to request.getSession(true) in an unsecure area of a website is untouched when the session transitions from the unsecure to a secure area of the website and from the unsecure to a secure area of the website. Am I understanding 1 and 2 right?

Tomcat 5.5 hot deploy question
Hi, From what I understand if I want a webapp to be auto deployed from a war file under tomcat I should have the following: Host name=localhost appBase=webapps unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false ... ... /Host The problem is that when I copy a new mywebapp.war file in to tomcat I see a half exploded Or deleted mywebapp folder. By this I mean that the mywebapp folder contains only certain folders and files. Any clues as to why this maybe happening? Is tomcat holding on to some jar files because some objects are being refrenced still or something like that? I am guessing here wildly because I cant seem to resolve this issue. What am I missing?

Re: JAVA_OPTS
I do not know what VM you are using. If you are using Windows and have tomcat as a service on there you will have to specify the -server option in the registry. If you are using Mac OS X you can specify it in the JAVA_OPTS As far as what the -server option will do for you , that depends on your VM vendor.

Re: Tomcat and -server option
Hi, I have: JAVA_OPTS=-server -Djava.awt.headless=true -Xms1g -Xmx1g -Dfile.encoding=ISO-8859-1 in catalina.sh I just tried: logger.info(java.vm.name: + System.getProperty(java.vm.name)); and i get: INFO - java.vm.name: Java HotSpot(TM) Client VM Why is the -server option not taking effect? Does java.vm.name display the mode the JVM is executing in or its name of the JVM installed on my machine?

forward to a form with enctype=multipart/form-data fails

Re: forward to a form with enctype=multipart/form-data fails
Yes :) . It is.
My ImageServlet gets a form submission of a form thats
enctype=multipart/form-data.
I am using the DiskFileUpload class from Apache using the
commons-fileupload-1.0.jar
DiskFileUpload upload = new DiskFileUpload();
List items = upload.parseRequest(request);
...
Since the request contains a multipart form submission, I can get data
from that request object once. The
DiskFileUpload object does this for me and returns a List object i.e.
items.
In doing so my request object looses all the parameters that I had
sent with it.
Now, when I do the following:
path = /c/shared/UserPhoto.jsp;
request.setAttribute(errorMsg, message);
getServletConfig().getServletContext().getRequestDispatcher(path).forwar
d(request, response);
This forward fails . And I am still at a loss of explanation.

Re: Design question ..
Hi, Yes , first come first is something that I prefer too. But I will need a singleton java object with a synchronized method to do the transaction. The transaction would involve 1. Check data 2. Register 3. commit data to database. After the method completes i can send them a confirmation. The downside to this approach is that if lots of users are registering for courses online , they might experience a delay.

Say user 1 submits before user 2. if user 1 registers before 2, a message is sent to the java bean in memory to update the cart 3. process the orders on a first come first serve basis, but do not gaurantee the person is signed up for it. In the response email state, you will get a confirmation of successful regisration. This is usually the easiest way to assuming you send confirmation in reasonable amount of time. This implies the transaction are processed async with some kind of queue 4. check availability before starting the transaction. this means some kind of locking at the row level. I'm sure there are other ways of doing it. Personally, I prefer handling the transaction on a first come first serve basis and send out confirmation in reasonable time. peter On Mon, 21 Jun 2004 12:37:04 -0700, Mufaddal Khumri [EMAIL PROTECTED] wrote: Hi, I am in the process of writing a webapp that allows users to make a payment and register for a course.

Re: Design question ..
I understand this method of doing it and I understand the pseudo code
too. I believe this code will be in a synchronized method that should
be placed in a singleton object. The code validates information. One
example validation could be getting current registrations for the
course and seeing if there is place left for this new user to enroll in
that course. If this method is not synchronized then two different
users
could be in this same function validating their data and then they
would try to register for the course too.
If the number of users using the system to register for courses is high
this singleton object encapsulating this synchronized method, would e a
bottle neck. Is there any other solution or is this standard
implementation?

Most commercial databases implement a solution to this problem since

You use the concept of transaction. To do this, you must turn the

Check
your documentation. If you are going through JDBC Connections are
always in
AutoCommit(true)!). You must also set the Transaction Mode to
Transaction_Serializable which locks table so that no one else then
you can
read the data in your tables.
The code looks something like this:
try {
//Validate information
//Add the record in the table
//Bill the customer
//commit transaction
} catch (SQLException) {
//rollback the transaction cause something went wrong
} finally {
//close the connection
}
Where you bill the customer is dicussable (it is related to the
transaction
but does not require DB access). It's all up to you really. A couple of
things to notice:
- TRANSACTION_SERIALIZABLE is the most demanding mode for your database
server.
- If you forget even one commit() or rollback() you might lose data to
locking.

Re: Design question ..
Hi Frank I understand this approach. The problem is that the course table has a field called maxregistration if this field is set to -1 it means that there is no limit. If there is a value in this field, it will be = 1. I have another table called Enrollments. This table has courseId, userId information. It keeps track of what user is enrolled in what course. I have a waitinglist table which has userId, courseId, timestamp. It keeps track of what users are waiting to be enrolled in a course that has met its capacity. The instructor can give override to users in waitinglist for a table. An override transfers a user from the WaitingList table to the Enrollment table. This means that at any given time the enrollment table could have more than course.maxregistration users enrolled for a course. Could you give me an example of a constraint that I could put on my tables so that it does not allow registrations more than course.maxregistration? On Jun 21, 2004, at 12:56 PM, Frank Zammetti wrote: Probably the easiest way to handle this is simply to have a constraint on your database that says a record cannot be added if some field is 0 (or a unique constraint, depending on how your table is keyed). Then, just catch the exception in your code and check to see if it's a violation of your rule, then return a message to the user saying the class has filled up. Simply put, don't worry about them putting the class in the shopping cart. Make sure you have a note on the site that says they are NOT actually registered until the shopping cart is processed. Then, let the database handle the concurrency issues (which they are very good at!) and you don't have to complicate your code any. I generally like staying away from database-level rules like this, just in case you tie yourself to a particular vendor, but something like this is pretty safe, and is tailor-made for such a mechanism.

Re: Design question ..
Yes, I could not said it better. I am not using clusters, but I certainly do want to stay away from the singleton and synchronization approach. It does have to be done at the database or with an extra table called Enrollment_Temp or something. Basically, when a user adds the course to his cart, an entry would be made in the Enrollment_Temp table and the current timestamp would be written to one column in this table. The current number of enrollments would thus be the sum of such entries in the Enrollment_temp and Enrollment table. If the user completes his transaction this entry from the enrollment_temp table can be moved to the enrollment table. This raises the question that there would be certain users who would not complete their transaction. Such users would cause entries in the Enrollment_temp table. We can have a timeout on the life of such entries in the enrollment_temp table. Have a thread clean the Enrollment_temp table if a condition like now timestamp stored + 30 minutes. If a user has a course in his or her shopping cart and does not complete his transaction, and if this was the last seat. For the next 30 minutes from the time he adds that course to his shopping cart, it wont be available to anybody. Q 1. Is this a good approach and is this judicious enough for users to use? Q 2. Can any improvements made to this approach? On Jun 21, 2004, at 4:07 PM, Frank Zammetti wrote: If your thinking in terms of singletons and synchronized blocks, it seems like you are thinking along the lines of doing this all in-memory. You CAN do that, but it's generally not a good idea. First, I don't know if your dealing with a clustered environment, but if you are you'll find that you have synchronization issues to deal with. Second, the obvious: if power goes out, everything is lost. If your dealing with a database, there's at least the possibility of recovering things. Third, any time you introduce a synchronized block in a J2EE-based application you have to ask yourself if your design isn't flawed because you are supposed to let the container handle all threading issues and your code should always be thread-safe. I myself have broken this rule on occassion, and I believe it to be valid to do sometimes, but you need to be sure it's truly the right anwer. Assuming you decide it is, realize that any synchronized block of code means your introducing a bottleneck to the application. You may decide it's insignificant, but you are essentially serializing all requests that go through that critical section, so you need to really make sure it's the right thing to do. In a recent app, I had a critical section during logon. This is very different than something that's a transaction within the app that might happen a number of times for a given user since the logon shouldn't be happening very often and you probably won't get too many users doing it concurrently, so it's not a big issue as compared to something that might be happening a lot for many different users. This really strikes me as something that should be done in a database, whether your letting the database handle the concurrance issues or you do so in your code yourself, but either way, that's really the way I'd be looking.

Date: Mon, 21 Jun 2004 14:34:51 -0700 Hi, Yes , first come first is something that I prefer too. But I will need a singleton java object with a synchronized method to do the transaction. The transaction would involve 1. Check data 2. Register 3. commit data to database. After the method completes i can send them a confirmation. The downside to this approach is that if lots of users are registering for courses online , they might experience a delay.

Simple question regarding Body Tags
I am using Tomcat 4.1.29
I have a bodytag called Page
In the constructor of this Tag I do this:
HttpSession session = null;
try
{
session = pageContext.getSession();
}
catch(Exception ex)
{
ex.printStackTrace();
}
When I use this tag on a JSP page and try to access this jsp page, I
get the following:

Re: Deployer problem
JSP 2.0 has no .tld files any more. Neither do you need to edit your web.xml file. You need to copy your tags to WEB-INF/tags directory. x1.tag file, must reside in WEB-INF/tags The jsp pages will have the following change: %@ taglib prefix=someTag tagdir=/WEB-INF/tags % someTag:x1 /someTag:x1 Hope this helps Mufaddal.

including a .jsp from within a taglib.
Hi,
I have a one.jsp on which i am using a taglib called pf:mytag
somepath='path'/
Inside the taghandler class i do the following:
try
{
pageContext.include(path);
}
catch(ServletException ex)
{
ex.printStackTrace();
}
path holds the path to another .jsp file that i want to include. I
have made sure that my taglib does get the path string.
pageContext.include(path) does not work for me. Have I to do something
more than this? Where am i going wrong?
Thanks.
Taglib problem with more information ...

I have two taglibs.
1. myTag1
2. myTag2
Both taglibs essentially do the following:
I have a one.jsp on which i am using a taglib called pf:mytag

Inside the taghandler class i do the following:

{
ex.printStackTrace();
}
path holds the path to another .jsp file that i want to include. I
have made sure that my taglib does get the path string.
This works for myTag1 but does not work for myTag2 ???
The difference between myTag1 and myTag2 is this:
myTag1 is a simple tag. myTag2 is a body Tag. Also myTag2 extends a
base taghandler class called myBaseTag.
pageContext.include(path) does not work for me in myTag2. Have I to do

URL rewriting question ..
In order to enable URL rewriting as opposed to storing cookies automatically we need to use the encodeURL(String url) or encodeRedirectURL(String url) method in the Servlets and/or JSPs. Is there a more easier way to do this as opposed to going thru the entire webapp and doing this for every URL or redirection ?

Nope. Tomcat won't look through your responses for things that look like URLs and append all the things you need (like sessison id, etc.). However, if you are using a framework like Struts, you can use the tag libraries provided to add both the context path as well as any necessary session information to the URLs. Unfortunarely, that still requires you to go back through all your pages and change all the links :( -chris - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: concurrent user threading problem
Hi Tamsin: I might face the same problem like you did. I am just wondering if you are still trying to find a way to make your webapp run on the new hardware with hyperthreading turned on? If yes, what if the compiler used to compile your code wasnt optimised for a hyperthreaded environment ? I might be wrong, but maybe compiling tomcat or / and compiling your webapp with a compiler that does optimizations for a hyperthreaded environment might solve the issue. If you are doing some tests in this regards and have results do let me know. Thanks.

Re: HOW CAN I USE THREADS IN TOMCAT
Hi, I have an instance of MyMailScheduler - mmsched in a ContextListener class for my webapp. mmsched spawns threads to do some work regarding sending emails. In my contextDestroy method I do : mmsched = null; I was under the impression that if tomcat was shutdown or the webapp was stopped my threads would be automatically killed since mmsched would be garbage collected. Am I understanding this right or do I need to do something else ? My webapp does two mail related tasks for two different sets of data. Both tasks are identical and therefore I spawn two threads. The two threads do not share any data structures. Also do I need to make the run() method synchronized ? Thanks. On Monday, November 3, 2003, at 08:45 PM, IvanLatysh wrote: Hello, Prince!

Re: HOW CAN I USE THREADS IN TOMCAT
Hi, The problem is that stop / suspend are deprecated. The destroy() method has yet not been implemented ? What does one do then? I have a solution - Keep a reference to the instances of the threads spawned in a hashtable. In contextDestroy make all these references null . Will this solution work ? Thanks.

Problem receiving huge text in IE
Hi,
Am using Tomcat 4.1.18. I have this problem on IE on Windows and Mac.
I am trying to get a huge amount of text from the database and want to
stream it to the user/s browser. Netscape and Safari work fine and
start displaying the text as soon as they start receiving it. IE waits
for the full text to reach it and then displays the complete text at
once. How do I get it to behave like netscape and safari where it
starts displaying what it has already received ?. My code for doing
this is below:
response.setContentType(text/html);
response.setHeader(Cache-Control, no-cache);
response.setHeader(Expires, 0);
response.flushBuffer();
PrintWriter out = response.getWriter();
out.println(htmlHead/Head);
out.println(body);
out.println(table width='100%');
for(...)
{
out.println(BIG lump of text);
out.flush();
response.flushBuffer();
}
out.flush();
response.flushBuffer();
Does anyone know why i am getting this problem with IE ? Have I to
tweak something in my code or tomcat webapp settings ?
Thanks.

two ways:
1. compile it into the tomcat work directory (expanded wars only)
(this option allows you to change JSPs on the fly)

2. pre compile it according tomcat docs, see docs

org.apache.catalina.startup.Bootstrap
Hello, I get a pop up icon for org.apache.catalina.startup.Bootstrap on my doc on MAC OS X when I click on the link in my web app which generates and sends a pdf file to the client browser. Once this popup is there the application works as expected, but if I quit this popup, tomcat shuts off automatically. Catalina.out doesn't show any log information for this action. If I run the same web app on Windows XP I do not get any pop ups. Here is the configuration of both platforms that I tested on, Platform: Mac OS X (10.2.6), Tomcat 4.1.18, jdk 1.4.1 Platform: Windows XP, Tomcat 4.1.18, jdk 1.4.1 From my search on the web, for this strange pop up behaviour, I learnt that org.apache.catalina.startup.Bootstrap is used to load the jar files at the application level. Here is the list of jar files that I use and are in WEB-INF/lib forlder of my application: 1. avalon-framework.jar 2. Batik.jar 3. fop.jar 4. xalan.jar 5. mysql-connector.jar (The first 4 are used in the pdf generation and the 5th jar is the mysql jdbc driver) I don't want this popup icon to appear in my doc of MAC OS X.

Standard error pages ?
Hi, I am using tomcat 4.1.18. I want to be able to redirect a user to a standard error page 500 when someone tries to access a .jsp in my webapp. Is there a standard mechanism to do this in tomcat or will i have to do: response.sendRedirect(response.encodeRedirectURL(/mywebapp/error/ error500.jsp)); instead is there something like: response.setError(500); response.sendRedirect(); // This would result in a standard 500 page being displayed instead of the error500.jsp page // i write. Any pointers / code snipets ? Thanks.
Problems with HttpSessionListener ..
Hi,
I am trying to implement the HttpSessionListener (the same class
implements ServletContextListener). The code for which is below.
1. I open a browser window , use MyWebApp after logging in it.
2. I open the tomcat manager and reload my MyWebApp. I go to the
console at this point and see the message - Session is already
invalid. (see code below)
3. I go to my window in step 1. and click on a link to go to a
particular .jsp page. I get a blank window. I check the session
attributes at this point and my session attribute USER_AUTHORIZED
exists and is true.
step 2 s result conflicts with step 3s result. (see code below).
Invalidating the session does not propagate to the client ??? What
am i doing wrong ?
public void contextDestroyed(ServletContextEvent sce)
{
// Destroy sessions.
if(sessions != null)
{
Iterator i = sessions.iterator();
while (i.hasNext())

Re: Problems with HttpSessionListener ..
From my tests so far , i found that the user browser is storing
cookies. So even when the container is not persisting sessions , the
client browser tries to use the old session stored in the cookie. I
was under the impression that if the user has an old session and tries
to reach MyWebApp , tomcat would detect an invalid session being used
and invalidate the old session . How do I deal with this problem ?

Subject: Problems with HttpSessionListener ..
Hi,
I am trying to implement the HttpSessionListener (the same class
implements ServletContextListener). The code for which is below.
1. I open a browser window , use MyWebApp after logging in it.
2. I open the tomcat manager and reload my MyWebApp. I go to the
console at this point and see the message - Session is already
invalid. (see code below)
3. I go to my window in step 1. and click on a link to go to a
particular .jsp page. I get a blank window. I check the session
attributes at this point and my session attribute USER_AUTHORIZED
exists and is true.
step 2 s result conflicts with step 3s result. (see code below).
Invalidating the session does not propagate to the client ???
What
am i doing wrong ?
public void contextDestroyed(ServletContextEvent sce)
{
// Destroy sessions.
if(sessions != null)
{
Iterator i = sessions.iterator();
while (i.hasNext())
{
HttpSession s = (HttpSession)i.next();
try
{
if(s != null
s.getAttribute(USER_AUTHORISED)
!= null)
{
System.out.println(Invalidating session
id =
+
s.getId());
s.invalidate();
}
}
catch(IllegalStateException ex)
{
System.out.println(Session is already
invalid.);
}
}
}
// End Destroy sessions.

cleaning up sessions ...
I have got a ServletContextListener that does initialization and cleanup for my webapp. I was wondering if there was a way to invalidate all sessions to my webapp in this Listener ? If not, in what way can I invalidate all sessions when i start / reload my webapp ? Thanks - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: cleaning up sessions ...
When i specify saveOnRestart:false and reload or start my webapp, the users navigating the website now have an invalid session .. on top of all pages i do a checkAuthetication .. how do i check if the session is active or not ? .. so that i can detect that and redirect them to the login page , before letting them go to where they were trying to go.

Re: cleaning up sessions ...
Hi, Does the PersistentManager help not to persist sessions across container start or restart ? or does it do across webapplication reload / restart ? (by container i mean Tomcat and by webapplication i mean a webapp that you run within Tomcat) From the documentation it seems that it helps not to persist the session across container restart or reload. If thats the case reloading my webapp only will not force the active sessions to that webapp to get destroyed or invalid. Am i understanding this correctly ? What I am trying to do: I have a webapp called MyApp that runs in Tomcat. When i restart or reload this webapp - MyApp (not restart Tomcat ) ... i want to invalidate all sessions to this webapp - MyApp. It could very well happen that when i reload MyApp , there could be users using that application and have sessions to it. In my ServletContextListener for MyApp i do cleanup work and initialization work. At this point i want to invalidate all active user sessions too - i want to do this inorder to detect that and redirect them to the login page where they would get a new session and then i would allow them to go to where they were originally trying to go. How do i achieve this ? Thanks.

Re: cleaning up sessions ...
Exactly. I have a session attribute in my session that i set to true . and if that session attribute is not present or is false i redirect them to the authentication page. I did the following to my server.xml : Manager className=org.apache.catalina.session.PersistentManager debug=0 saveOnRestart=false maxActiveSessions=-1 minIdleSwap=-1 maxIdleSwap=-1 maxIdleBackup=-1 Store className=org.apache.catalina.session.FileStore/ /Manager Now i go to the tomcat manager and reload my webapp . I am navigating the webapp in a browser when this happens (ie i am currently a user using a valid session ) .. after the webapp reloads ... i continue using the webapp by clicking on say a link ... which takes me to some other jsp page ... i do a check on top of this jsp page for this attribute ... and it still persists . This is what threw me off .. and i could not understand where i was doing what wrong ... Any help appreciated Thanks.

Re: cleaning up sessions ...
To test I did the following: 1. started tomcat. 2. started a browser, logged into MyApp and used it. 3. stopped tomcat and restarted tomcat . (kept the browser window open). 4. went back to my browser window and tried to continue using my MyApp by clicking on one of the links to a jsp page. The browser showed me a blank window - AT THIS POINT I checked the session attribute and it was still existing. My code that redirects the user to the login page checks to see if this attribute is not there or is false. Since its present and is true it does not redirect the user.

Yes, thats a helpful function ... I was looking at :
http://jakarta.apache.org/taglibs/doc/string-doc/string-1.0.1/
index.html
to see if i can find a good tag library to use ... havent found one
that i could use yet. Am hoping that someone on the list has pointers
to some standard function or taglib.
Thanks.

Hi,
Am using tomcat 4.1.24.
Have a XYZ.jsp with a form on it take data from the user. Once the
user
clicks submit the data is stored in the database and the data that
the
user entered is shown to him on ABC.jsp.
The problem is that the user can enter anything in the text field and
text area of the form on XYZ.jsp. For example in the description text
area he or she might enter - text, an http url, maybe html tags etc.
Now when i grab this data from the form and store it to the databse
it
works fine, but when i grab the data from the database and render it
on
ABC.jsp it gets messed up because the html tags in the data interfere
with the html of the page. Is there a way in tomcat escape such
characters or are there java methods that i could use to pass this
string through that would do the escaping for me ?
Thanks.

Tomcat 4.1.24 causes refresh problem ... 4.1.18 does not.
Hi, Added : % response.setHeader(Cache-Control,no-cache); response.setHeader(Pragma, no-cache); response.setDateHeader(Expires, 1); % The problem still persists. This problem does not occur with tomcat 4.1.18, but occurs with tomcat 4.1.24. IE , Netscape and Safari work fine with 4.1.18. Safari does not work well with 4.1.24 in regards to refresh. Am using safari on mac os X with tomcat 4.1.24 ... I have two .jsp files - LocationInformation.jsp and EditLocation.jsp LocationInformation.jsp shows me the information of a location from the database. EditLocation.jsp is used to edit the information for a location and saved to the database. On the LocationInformation.jsp I have a link to EditLocation.jsp. When I edit the location information by entering data in the form on EditLocation.jsp and then say submit, the data gets entered in the database and I take the user to the LocationInformation.jsp where it shows the updated information from the database. When I click the link to EditLocation.jsp on this page, it takes me to EditLocation.jsp and the form on EditLocation.jsp shows me the old information. When I click the refresh button in the browser the form shows me the updated data. Does anybody know why or how to solve this problem ? Thanks.

Resolved Re: Servlet Context Listener problem...
CHANGED the reference to the dtd and it worked. That was the error because I was referencing the old dtd which does not recognize listener or listener-class. I had: ?xml version=1.0 encoding=ISO-8859-1? !DOCTYPE web-app PUBLIC -//Sun Microsystems, Inc.//DTD Web Application 2.2//EN http://java.sun.com/j2ee/dtds/web-app_2_2.dtd; Changed it to: ?xml version=1.0 encoding=ISO-8859-1? !DOCTYPE web-app PUBLIC -//Sun Microsystems, Inc.//DTD Web Application 2.3//EN http://java.sun.com/dtd/web-app_2_3.dtd;
contextDestroyed being called twice ???
I have defined a listener class that implements:
public void contextDestroyed(ServletContextEvent sce) { ... }
The problem is this method is being called twice when i use the tomcat
admin manager to reload the webapplication by clicking on the Reload
link. Why does this happen ? Is this correct behaviour ?
Thanks.
