wrestling with JSP error page
Hi, all. I'm finding that the JSP errorPage directive has a serious flaw. Perhaps others out there have run into this and been as frustrated as I am and hopefully come up with some solution...? The flaw is that, if the response has already been committed, then the error page is just plopped into the response where the error occurred - it has no way that I see of generating a fresh response with just the error page content. Then the problem is that, depending on where the original page died, the error page content may not get displayed if it's caught inside some HTML tag where the browser can't figure out how to render it. Just as an example of this which I've seen, say you have a select dropdown list populated from some List request attribute, so you output select and then go to iterate through the List. Now, say the List is null, and a NullPointerException is thrown, the errorPage content gets put into the response right after the select tag and the browser doesn't display it. (You can see it if you do View - Source, but this obviously defeats the purpose.) This is quite annoying, and I'm amazed that this mechanism still hasn't been improved. I searched for solutions to this, but the only thing I could really find was using another framework like Velocity which buffers the whole response and therefore can generate a completely different one if an exception occurs at any step of the way. Unfortunately, learning another framework just isn't in the cards. Does anyone know of a way, besides maybe making the buffer size really huge, to get around this problem? Would a Filter on the response help with this? How would something like that work? (Never written/used a Filter before) Thanks! -Jeff
Re: UTF-8 Sending Euro symbol to Servlet in Form data.
Hi, Andoni. I'm not 100% sure how this all works, but I think there's a default system encoding on the system where your Tomcat is running. This encoding determines how the form request parameters come across. I think when I ran into a similar problem a while back I got around it by doing something like this: String param = request.getParameter(param); byte[] paramBytes = param.getBytes(UTF-8); String paramToDatabase = new String( paramBytes, UTF-8 ); Then, you can send paramToDatabase to the database. See if something like that works for you. I've also seen discussion on this list about using Filters to intercept the request and handle this kind of thing, but I've never dealt with that.

Re: Installation woes
Open a terminal window yourself first, then run %CATALINA_HOME%/bin/startup.bat. Now you should be able to see the error message without the window disappearing on you. Also, make sure the JAVA_HOME points to the top level directory of your JDK (C:\jdk1.3 instead of C:\jdk1.3\bin for instance). Also, I don't know if things have changed with the more recent versions, but I seem to remember there being problems with the installations in previous versions, and it was generally recommended to just download the binary release (sufficient unless you want to take a look at and/or tweak the source code), unzip, and set the environment variables.

Re: Session timeout setting (URGENT)
Hi, Kenny. I think this is basically how it works: - Tomcat's conf web.xml sets the default session-timeout (in session-config element) to use for all web apps. - You can specify a different session-timeout in each specific web app you deploy in the web app's WEB-INF/web.xml file. - This session timeout can still be overridden in application code using the session.setMaxInactiveInterval method. I hope this helps you find the problem. -Jeff Kenny G.

Re: Tomcat 4 StandAlone Web Server, Static HTML and Images

RE: global.jsa - Struts
If you're looking for a very basic MVC implementation, you can use a small part of what Struts offers and be able to save the time you would spend writing your own. You do pretty much exactly what you wrote in your second paragraph. Set up your struts-config.xml file to define your actions and valid paths that could result from the action (which JSP to show) and implement the defined action classes to process the data coming from your JSP. No need to bother with action forms or taglibs at the moment if you do in fact have a fly in your cannon's crosshairs. That's about it - voila, an MVC implementation with very little pain. Obviously, there are tons more features available in Struts which you can explore and use as you see fit.

You should always separate design from implementation. About Struts: yeah, we need lots of taglibs to avoid writing Java code in JSP. So, taglibs for standard APIs are welcome. But Struts goes too far, with taglibs to generate form tags, etc. These things (html forms) normally are generated by dreamweaver users, so i don't like strut's approach. And there are lots of talibs avaliable on the net, including jakarta site itself, so I don't need Struts. MVC-style programming is great.

Re: Re[4]: Quick Question
Hi, Alex.
Since JSP's are turned into servlets before they are executed, I don't
see why you couldn't do this. For your convenience, JSP's have some common
objects already available for use. The application object is equivalent to
the javax.servlet.ServletContext object you would get by doing a
getServletContext() call. So, application.getInitParameter(key) should do
the trick, too.
HTH,

Hello TOMITA,
I know next to nothing about JSP. Haven't touched it. I use XMLC and
Barracuda to do presentation. However, I would think that you should
be able to use getServletContext() or something analogous in JSP.

OT: howto avoid overuse of session object?
This is sort of off-topic, but I don't know of a better forum targeting Java web/servlet programming. If anyone does know of one, could you let me know? I'm basically wondering if others have found effective ways to avoid the tempting but bad practice of loading up the session with all sorts of attributes. I often find myself needing some Bean or other object for maybe 2 or 3 requests, and, rack my brains as I may for an elegant way of passing the object along without putting it in the session, I usually end up with nothing more than a headache and 1 more attribute in my session. :( I'm developing with an MVC approach, with Struts for more recently developed apps and a similar custom framework for our older apps, but I just can't seem to see a way to get around this problem. I would love it if there were an object like a thisRequestAndTheNextOne object, where attributes would stick around for the current request and subsequent request, and then the controller could get objects from the previous request and determine if it should put them in the new thisRequestAndTheNextOne object for the current request. I don't know if that makes sense to anyone else, but, nevertheless, does anyone have any ideas to do what I'm trying to do? Does anyone else feel my pain? ;) Thanks, -Jeff -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Re: howto avoid overuse of session object?
Thanks, Cédric and Peter Lin, for your responses. Both of you seem to be saying that, instead of storing large objects in the session object, I should be storing them in the application object (ServletContext). I find this to be rather confusing. It seems like the overhead involved in storing things in the application object would be much greater than storing things in the session object. At least the session objects would eventually die when sessions time out or they are invalidated by the web app, and the space they were using could then be garbage collected. But the application objects would live as long as the server is up, and I would think would eventually consume memory moreso than using the session would. Also, there would be a extra level of complexity involved with maintaining the association between the objects in the application object and their respective sessions. Am I unclear on the concept, or is there something else that I'm not understanding?

This also depends on when you want the code executed. I believe overriding init will only make that code execute when the servlet is first created.

Hi, Dave. Did you check your log files for exceptions? I've seen behavior similar to what you're describing with Tomcat 4.0.x running Standalone.

Then, it runs into a NullPointerException (or probably some other exception, but, usually for me, it's a good ole NPE) while trying to generate the next buffer's worth of content. At this point, the browser doesn't show an error page but just stops with only the one buffer's worth of content displayed. Maybe Apache renders the page as blank, but I usually get the partially returned page, as far as it can be rendered. Besides the partial page, the only sign that something went wrong is in the log.

Re: Beans in packages vs beans not in packages
Hi, Ron. This is because Tomcat puts the servlets generated from JSP's in the org.apache.jsp package. Therefore, when you reference your bean with no package specified, it looks for it in this package and does not find it there. You should see that as part of the error message - something like Cannot find class org.apache.jsp.YourBean. Hope that clears things up. -Jeff Ron Day ronday@rondaTo: [EMAIL PROTECTED] y.cccc: Subject: Beans in packages vs beans not in packages 07/10/02 05:20 PM Please respond to Tomcat Users List Hi, When I run a webapp with a bean in a package -- say com.form, everything works fine.

Re: Cannot use bean from jsp, but servlet ok. I'm dying!
I think it is just a simple syntax error. The JSP expression tag on your
userName text field is incorrect - needs to be %= without the space. You
have a scriptlet with =FormBean.getUserName() trying to be executed. It's
interesting to see that it looks like Tomcat equates an equals sign before a
class as an out.print on that class.

Help. Absolutely stuck. Tomcat cannot find my bean classes no matter what
when called from jsp pages. From within servlets no problem.

}
}
NO MATTER WHAT, as soon as I access the jsp page. This error comes up.
Generated servlet error: C:\jwsdp-1_0\work\Standard
Engine\localhost\messagesmith\en\users$jsp.java:126: Undefined variable or
class name: FormBean out.print( FormBean.getUserName() );
It certainly seems that TC cannot find the FormBean class which lives here:
C:\jwsdp-1_0\webapps\project\WEB-INF\classes\beans.
I've changed that scope attribute to application or page, but it doesn't
change.
With TC3.x I had to do some configuration in the conf/server.xml file, but
this doesn't seem necessary w/ TC4. All the same I've adding the following
context to the server.xml, but it doesn't help.
Context path=/project

Anyone have any ideas? It is killing me. Again, I can instantiate the
FormBean class from within servlets, but not from JSP.

Re: Cannot use bean from jsp, but servlet ok. I'm dying!
Actually, no, it looks like I was mistaken. Looking again at the error
message, it does seem like the seemingly malformed tag is understood to be a
JSP expression tag and the generated servlet code is correctly set to
out.print( FormBean.getUserName() ); Sorry, don't know what the problem is
then.

RE: Need Ideas... big problem! (long)
Well, the classes themselves wouldn't be used to get the init params or read the db.properties file. You would use a Servlet to do that, and then you would just pass the params (or Connections created from those params - however you're doing things) to the instance of the DAO class you would be using in your application/session/request.

Hi, Christian. I would recommend now taking a good look at the Java Servlet Specification and letting all these suggestions digest while you go through that. Things should start to make more sense once you have a better handle on servlets. Maybe take a look at the Tomcat servlet examples too. Your servlet should definitely have access to the request object, since if you look at the specs on HttpServlet, you'll see that it is passed as a parameter to its various methods.

You've got at least the following options: * Call request.getContextPath() and you'll get the context path of the web application that is responding to this request. * The application object in a JSP page is in fact the ServletContext for the current webapp, so you can call things like % Properties props = new Properties(); InputStream stream = application.getResourceAsStream(/WEB-INF/myprops.properties); props.load(stream); stream.close(); % to load a properties file from inside the WEB-INF subdirectory of your web application. As a general note, however, you should really be doing this sort of thing in startup code of a servlet, which stashes the results as servlet context parameters for everyone else to use. Using scriptlets to mix functional logic into your JSP pages is going to cause you maintenance nightmares over time.

exaclty... I looked on HttpServlet... request and response are passed as
parameters... so I don't HAVE it. And since it's passed as a parameter I would
have to change 150 JSPs to pass this new parameter...
and I don't wanna change anything, only create a new class... if in the
solution comes changing all the JSPs and classes I'm sure that's not the best
one... I may have asked the wrong question... let's say:
public class TesteDispatcher extends HttpServlet {
private static final String CONTENT_TYPE = text/html;
//Initialize global variables
public void init() throws ServletException {
}
//Clean up resources
public void destroy() {
}
public String doSomething() {
// this is the method...
}
}
Is there anyway doSomething() can know in which Context it was called?
Remember that this class is in \common\classes.

Re: Database locked by Tomcat
Hi, Kevin.
Correction: Database locked by YOU! :)
You've closed the statement but not the connection. You need a conn.close()
after the commit. This shouldn't lock the database by itself, although if you
keep leaving connections open, then you will eventually hit a connection max
limit, which could be what's hanging it. I would also recommend that you put
all that stuff in a try block and finally close the connection, something like
this:
Statement stmt = null;
Connection conn = DriverManager.getConnection(dbfUrl, , );
try {
// do some stuff
conn.commit();
}
catch(Exception e) {
conn.rollback();
}
finally {
if ( stmt != null ) {
try {
stmt.close();
}
catch(SQLException e) {
// handle or ignore
}
}
conn.close();
}

I am Running Tomcat 4.0 on Windows 2000. I have a servlet, which calls a
program that connects to a DBF database natively (not using JDBC-ODBC) and
updates records in the database. The problem I am having is that Tomcat does
not release the database until I restart the Tomcat service. I close the
connection and even do a commit(). Has anyone else had a problem and if
so, is there a solution? Below is some sample code:
Class.forName(dbfDriverName).newInstance();
Connection conn = DriverManager.getConnection(dbfUrl, , );
Statement stmt = conn.createStatement();
// do some stuff
statement.close();
connection.commit();

Re: Jspc i18n
It looks like the output is probably in UTF-8 format. If you use the %@ page contentType=text/html;charset=UTF-8 % directive in your page, that should instruct the browser to use that encoding for display. To see if this should work, you should be able to just manually change your browser's encoding to UTF-8 (Unicode) while viewing the page that currently doesn't work and have it display properly for you.

Hi, Christian. I haven't run into this problem before, so I'm not sure, but it looks like the compiler is encoding the accented characters. Perhaps if you specify the JSP page's encoding, it won't do that anymore...?

Re: Multiple users share java bean?
If you have multiple users sharing the same bean, then that's what's going to
happen. By synchronizing the get and set method, all you're doing is saying
Make sure the user finishes this whole get or set method before any other
user can start it. However, that won't prevent another user from calling the
set method right after the first user does and before the first user has a
chance to call the get method. Are you sure you want multiple users sharing
the same bean here? Or do you want multiple users using multiple instances of
the bean (what it sounds like to me)??

Dniel,
There is still one problem: the value set by the second user2 updated the
value of the first user1 before finishing user1's work. I paste the code.
Please take a look.
public class test
{
int numEvents= 5;
public synchronized int test()
{
int real=0;
int eventCounter=0;
while(eventCounter=numEvents)
{
real=eventCounter;
// wait for 0.01 second
try{wait(10);}
catch(InterruptedException e){};
eventCounter++;
}
return real;
}
public synchronized int setNumEvents(int sec)
{
numEvents= sec;
}
}
For example, I input 200 as the value of numEvents for user1. Before
finishing user1's task, user2 input 100 as numEvents and begin his work. I
hope I can get results 200 and 100 respectively. But I got 100 both.

If it's a shared bean, sycnchronize it. Make sure that
all mutators(Setters) are synchronized, and it would be a bad idea to do
that to the
accessors (mututors) are synchronized too. If you have more open than
private member variables in this bean, make sure they are private.

Re: Large pages not completely displayed with IE 5.x and Tomcat 4 .0.x
I ran into what I think is this problem before too, and here's what I ended up finding... I noticed the same thing as you, that the HTML was incomplete. My HTML was stopped right in the middle of a big list of SELECT OPTION's. I thought there was something wrong with the particular option that it died on, but then I added some more options to the database before that option. The HTML then stopped on a different option. I noticed that the HTML source for the page with the problem was always 16k. I checked my JSP page buffer size, thinking that it was 16k and there was something causing it to not flush subsequent buffers, but I found that my buffer was set to the default of 8k, so I was getting 2 buffers' worth of output. I checked the logs and found that I had gotten a run-time exception in the execution of my JSP page towards the end of it. So, what it looked like was that, if it got a run-time exception but had already sent back a full buffer, it was not sending the usual exception stack trace in the resulting page. I was thinking that this might be a Catalina bug (was using 4.0.1), but I didn't investigate this further after I fixed the cause of the run-time error. Hope this helps. -Jeff Robin Lee tech_supportTo: Tomcat Users List [EMAIL PROTECTED], Michael @uls.comGerdau [EMAIL PROTECTED] cc: 03/12/02 Subject: Re: Large pages not completely displayed with IE 5.x and 11:05 AM Tomcat 4 .0.x Please respond to Tomcat Users List Hi, I had the same problem as you did...

So, after some checking and testing, i discovered it is because i had too many objects open. (Instantiated objects galore). One thing i did to make it work is to make sure that each object that i instantiate is opened ONCE... (I use a java mapping strategy to get data from the database). Once i did that, the rest of the data would show up with no problem... That is one thing i would check and see if there are too many objects being instantiated (same ones all the time).

RE: How can I resolve this IllegalStateException: Response has a lrea dybeen committed problem?
If you are getting any pages back from the server, then you are using the response object! You may not be manipulating it with an explicit reference to it, but, when you have HTML or do an % out.println(STUFF) % or output a JSP expression like %= something % in your JSP pages, you are using the response object. And the deal is you can't forward if you've already started putting stuff in the response. What you should probably look into, and what some people are hinting at here, is using some sort of controller servlet that gets the request and then CALLS (not forwards to) the appropriate handler or action class. You can pass the request object along to your handler class so that you can get stuff from it or its session. Then, when your handler method is finished, you controller picks up immediately following its call to your handler. This allows you to have one very general controller servlet which can route the requests to more specialized handlers or actions depending on some parameter (command, action name) and can then handle forwarding to the appropriate new page. You might want to take a look at the Struts framework, which does this for you. Hope this helps. -Jeff lindsay.hamou [EMAIL PROTECTED]To: [EMAIL PROTECTED] cc: 03/08/02 Subject: RE: How can I resolve this IllegalStateException: Response 08:43 AM has a lrea dy been committed problem?

The only time I ever knew I was using the response object was when I used response.sendRedirect(), but I don't use this anymore. I use the RequestDispatcher. There are no jsp:include or jsp:forward tags being used anywhere, and my servlets do not contribute anything to the response (apart from forwarding it around). Mark - your words of wisdom interest me. I thought that... when I invoke requestDispatcher.forward(), then control never returns (to the line following this invocation).

Re: still suffering character-encoding woes
Hi, Richard. I can definitely relate. This frustrated (sort of still does frustrate) me to no end. Let me try to explain what I understand after wrestling with this for a while. (gurus, if anything isn't quite right, please chime in!) 1.) The following are all supposed to have the same effect: - setting the META HTTP-EQUIV=ContentType CONTENT =text/html;charset=UTF-8 - using the JSP page directive %@ page contentType =text/html;charset=UTF-8 % - specifying response.setContentType(text/html;charset=UTF-8); These are all supposed to tell the browser what encoding to use when displaying the page it gets. I have found that the JSP directive works the best for me. The META tag didn't seem to be consistently working for me, and I find the JSP page directive easier to use than the response.setContentType. 2.) On the receiving end, when values are passed to you in the request, that's another issue. I'm not too sure how the charset for passing parameters is determined. I believe that they will be encoded according to the encoding of the page with the submitting form. I've also seen some discussion on specifying the char set in the Form tag, but it sounds like that doesn't work very well. Anyways, I have been able to get my parameters ok by setting the encoding for the page with the JSP directive mentioned above and then getting the parameter values like this... String param = request.getParameter(param); byte[] bytes = param.getBytes(UTF-8); String paramForDB = new String( bytes, UTF-8 ); I don't really understand what kind of transformation is happening with the getBytes and creation of the new String (***Can anyone else explain this to me?***), but it seems to get the job done. 3.) Also, make sure that your database can handle high-bit or extended ASCII values (greater than 127) in order to store the UTF-8 encoded data. Hope this helps.

I've tried every suggestion that I saw in the threads to no avail, and am starting to tear my hair out. A quick summary: My development environment is Apache1.3.20, Tomcat 4.0.1, DB/2 on Windows2000, locale = Norwegian My production environment switches the database to Postgres and OS to Linux, environment has LANG=C and LC_CTYPE=iso-8859-1 Basically, on my development environment, everything works perfectly- i can post data containing norwegian characters and they are stored properly in the database and logged properly in the log files. On the production server, its '?' everywhere. Now to fix the problem, I've tried the following steps, in sequence: 1) I cut apache out of the loop and accessed tomcat directly to see if it interfered at all- no change 2) I added META HTTP-EQUIV=Content-Type CONTENT=text/html;charset=UTF-8 to inside my html-head tags 3) I added %@ page contentType=text/html; charset=UTF-8 to my JSP pages 4) Finally, I tried doing request.setCharacterEncoding(UTF-8) at the top of my doGet and doPut methods None of the first 3 steps helped- still that '?'- I should point out that
Re: Newbie can't run own JSP in Tomcat (404 - File Not Found)
Hi, Brian. This doesn't tell you that it can't find the class referenced in your JSP page. If that were the case, you wouldn't have gotten a 404 error - you would've gotten to a page with a class not found exception. That tells you that it can't find the JSP page itself. In order for Tomcat to know about your JSP page or a web application, you need to tell it about the new web context or put it somewhere Tomcat will naturally look for it. Tomcat will automatically create contexts for directories in its webapps directory, so one option would be to create a directory in there like mytest. If employees.jsp were in that directory, you'd go to http://localhost:8080/mytest/employees.jsp to get to it. The other option is to edit the conf/server.xml file to define a context somewhere else. There should be example(s) in there, so look at those and you should be able to figure it out. Hope this helps. -Jeff Brian PeaslandTo: [EMAIL PROTECTED] peasland@usgcc: s.gov Subject: Newbie can't run own JSP in Tomcat (404 - File Not Found) 02/17/02 11:17 AM Please respond to Tomcat Users List Hello, I'm running the following: Tomcat 3.3 w/ JDK 1.4.0 Microsoft IIS 5.0 I installed Tomcat as per the directions in Tomcat IIS HowTo.

restarting Tomcat 4
Hi. I was wondering if anyone out there has a good way of restarting Tomcat 4...? In version 3, I used to just be able to do $TOMCAT_HOME/bin/shutdown.sh; $TOMCAT_HOME/bin/startup.sh. Now, in version 4 though, since the starting and stopping scripts seem to have been modified to be background processes, this no longer works since it won't wait for the first script to finish anymore before starting the second one. Now, my restart alias looks like this: $CATALINA_HOME/bin/shutdown.sh; sleep 40; $CATALINA_HOME/bin/startup.sh. Pretty lame, and I just arrived at the sleep value by trial and error (actually as I add more stuff in my server.xml file, I think the shutdown might even take longer, so I may need to bump this value up). Does anyone have any more elegant/exact ways of doing this?

Re: Internationalization
Hi, Christopher. Here are some things to look into... - Make sure that your JSP page is set to use a font that can display the specific Unicode characters. If it's just a specific subset of the Unicode character set, then you may be able to find a lightweight font that handles that specific subset. If you need support for the whole Unicode character set, the only font I've found so far that handles this is Arial Unicode MS, which is a BIG font (about 24 Megs) and unfortunately, as you may have deduced from the MS in the name, is Microsoft and therefore a Windows-only font. - You may need to do some conversion of the parameter values coming over in the request or values that you retrieve from your database. I've been able to get the values out of the database (Oracle configured as extended-ASCII character set) by doing something like this... byte[] bytes = resultSet.getBytes(1); String stringToOutput = new String(bytes, UTF-8); Hope this helps!

Re: Redirect after session expires?
There is no session.isInvalid() method - that wouldn't make any sense anyway. If you have an actual session to ask if it's valid or not, how could it ever be invalid? There is an isNew() method, and I have not used this, but from reading the spec it doesn't sound like it will do the trick. There is a way to define an errorPage, a page that your JSP will forward to if it throws an Exception. %@ page errorPage=relativeURL % You'll have to put this in each of your pages though, so it might not be what you're looking for, although then all the logic to handle the exception would just be in the errorPage. You could also look into binding the session by creating an object that implements HttpSessionBindingListener. Then when the session expires, the valueUnbound( event ) method will be called by the servlet engine. You could put code in that method to handle this case. Hope this helps. -Jeff Michael Molloy To: Tomcat Users List [EMAIL PROTECTED] mmolloy@ncyccc: les.com Subject: Re: Redirect after session expires? 02/13/02 09:54 AM Please respond to Tomcat Users List Well, we're trying to keep as much logic out of the jsps as possible, so if there is a setting for web.xml or something to foward all pages that throw exceptions to a certain url, that's what I'm looking for.

Re: Switching on UTF-8 Encoding
You can use %@ page contentType="text/html;charset=UTF-8" % in the JSP or
alternatively include the META HTTP-EQUIV="Content-Type" CONTENT="text/html;
charset=UTF-8" tag in your HTML. This will tell the browser to use the UTF-8
Encoding.
Then when getting the requests, you can do a request.setCharacterEncoding
("UTF-8") before getting anything from the request to allow you to read in
parameters as UTF-8. You could also try just reading in the parameters
without setting that, and then doing param.getBytes("UTF-8").
I've been struggling with some encoding issues for a little while now, but I
have it working, so if you have any other questions, please feel free to email
me and I'll see if I can help.

Re: getInitParameter from within a bean?
Hi, Ross. This sort of defeats the purpose of beans. You should develop your beans without any dependencies whatsoever on servlet-specific stuff, like requests or sessions. This way, your model is independent of the web environment and could be used in some other context. Your servlet should get the request and handle it and also figure out any init parameters. Then, just pass the bean whatever it needs.

Hi, Michael. The %@ include ... % tag is a static include, and, once the page that includes something like this has been compiled, a change to the included file will not trigger a recompile of the page.

The jsp:include .../ is a dynamic include that will cause the main page to be recompiled if the included page changes.

form values being sent as HTML entities instead of UTF-8 chars
Hello. I'm having a problem which I believe is related to Tomcat 4, since I didn't see this happening on 3.2 before I upgraded. I have a form on a page that is set to UTF-8 character encoding. When I paste a Unicode character into an input field and submit the form, the characters are being received as HTML character entities ( for example, #1234; ) instead of the UTF-8 bytes. There seem to be so many encoding settings all over the place, and I'm really confused as to which settings control what. I used to just have the META HTTP-EQUIV=Content-Type CONTENT=text/html; charset=UTF-8 tag in my page, and things worked fine before the upgrade. I thought that the tag would tell the browser which encoding to use, and it would handle displaying content using that encoding and would also submit form values in that same encoding. But, it seems as though Tomcat is affecting how the values are submitted. I've seen some discussion of a character encoding filter, but I'm not sure how it all works. I've seen a bunch of different things: the META tag, using a page directive for contentType, using a page directive for pageEncoding, using request.setCharacterEncoding, using response.setCharacterEncoding, using this SetCharacterEncodingFilter class. Could anyone offer some clarification of what the different ways to set character encoding do differently and in what situations they should be used? Thanks in advance for any light you can shed on this for me! -Jeff -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]
