RE: [Proposal] Default Encoding option for JSP/Tomcat in server.xml or web.xml
Hi Craig, For POST requests, the request parameters will be parsed in the character encoding specified by the browser (as part of the content type header). If they did not, a new feature in Servlet 2.3 lets you call request.setCharacterEncoding() before trying to read any request parameters, if the app knows what character encoding was used. I personally have never seen any browser specifing a character encoding while POSTing FORM data. In general it seems to use the encoding of the page containing the form to encode the POST data but if the user chooses to change that it never tells the server in the POST request. Am I missing something? Cheers Christian -- Christian Mallwitz INTERSHOP Communications Germany Senior Software Engineerphone: +49 3641 50 3453

Jasper Architecture Question (Was: How to do my own JSP processing)
-Original Message- From: Craig R. McClanahan [mailto:[EMAIL PROTECTED]] Sent: Thursday, December 21, 2000 19:23 To: [EMAIL PROTECTED] Subject: Re: How to do my own JSP processing Sounds like you are planning on inventing your own variant of a servlet+JSP server, since you're wanting to change or ignore many of the spec requirements. And you will end up with an app that will only run in your own server. Unless you like building servers as a hobby, you've got a *lot* of hard work ahead of you. I would suggest you look at how you can architect your application *within* the requirements of the servlet and JSP specs. That way, you can focus on writing an app rather than a server, and have some assurance that you can run that app elsewhere if and when you outgrow Tomcat. Actually I have my own template language which is compiled to a JSP file. Everything is supposed to be as much Servlet 2.3 spec conformant as possible. Here is a simplistic view on my main servlet service() 1. begin database transaction 2. do some business logic 3. execute JSP file 4. commit transaction 5a. if commit successful send response content to the network 5b. if not generate error response (and discard result of JSP) The problems with 3.) are I.) the JSP files are located outside my servlet context II.) JSP execution must be buffered because the content is not be sent before the database transaction commits III.) the JSP execution must be able to set response header lines (e.g. cookie) IV.) it should be possible in JSPs to use tag libraries and do all other things possible if the JSP is served directly by Tomcat Because of I.) I cant use a "simple" servlet request dispatcher II.) forward() won't work because if the forward() returns the response is already committed and closed by the container III.) includes() won't do because I can't set headers On top of this I want my servlet to pick a JSP file, run it, capture the output and send this output be email before saying "sending email was successful." over HTTP. From what I read about Jasper it should be possible to call it compile my JSPs and trigger their execution independent of the all of this is running in a servlet itself or a standalone application, right? Thanks Christian PS: I know it will be a nice piece of work ... -- Christian Mallwitz INTERSHOP Communications Germany Senior Software Engineerphone: +49 3641 50 3453
JASPER: largeFile init parameter
Hi, I want to use the largeFile parameter mentioned in the FAQ but couldn't get it to work. Jasper always generates static HTML content into the Java class file. How can I change this? Thanks Christian -- Christian Mallwitz INTERSHOP Communications Germany Senior Software Engineerphone: +49 3641 894 334 -Original Message- From: Christian Mallwitz [mailto:[EMAIL PROTECTED]] Sent: Monday, November 13, 2000 16:49 To: '[EMAIL PROTECTED]' Subject: RE: largeFile init parameter I tried JSP files of different sizes up to 512 KB size. All static text is generated into the class file. So how do I enable the largeFile option? I read about the largeFile init parameter and set it to true in my conf/web.xml file. but the static HTML is still in the class file. The FAQ says: "If the file is really large then all the static html is stored is a separate data file if the value of this param is set to true." How large is large and can I modify that?

Please follow up on this in tomcat-dev as well ...

Hello Tomcat developers and advanced users!
I have following question:
I would like to use Jasper engine for template processing. I use
Tomcat with JSPs and its good, but I would like to alter Jasper usage
this way:
An JSP page is compiled into a Java source where the user's JSP
page extends the class HttpJspBase and overrides several methods
notably _jspService().
I want to use Jasper for more generic task. Template processing
independent on Servlets and HTTP. Imagine following interface:
public interface Template {
void renderTemplate(Writer out) throws java.io.IOException;
}
I want to alter Jasper to process files with JSP-like syntax (of
course with other intrinsic variables accessible inside the
renderTemplate() method) and generate Java source code implementing
the Template interface and than compile the source code using Java
compiler into executable classes. Then load and run generated classes
as they have been written manually.
So I ask:
1) is it possible or is Jasper tightly coupled with HTTP and Servlet
API?
2) if it is possible, how to do that? (which classes can be re-used,
which interfaces and classes have to be re-implemented
3) how much time it can take (1 day, 3 days, a week, two weeks, ...)
Thanks for any comments and suggestions.

tomcat 4.0 m4: bug while submitting UTF-8 data to JSP page
Hi, I have a JSP file (see attachment) which lets you submit text in UTF-8 to the same JSP file. For this to work the JSP file contains code for converting the submitted text from Unicode to UTF-8. I run some test to submit the Euro symbol. In Unicode this is code point 0x20ac and in UTF-8 it is 0xE2 0x82 0xAC (3 bytes). It works for all servlet engines I know of incl. Tomcat up to 3.2 beta 6 but not for Tomcat 4.0m4 if you have an URL like http://host/post.jsp?text=%E2%82%AC I expect the following output: text [as text] = â'¬ text [as hex]= 0xe2 0x82 0xac text [corrected] = EUR but I get text [as text] = â'¬ text [as hex]= 0xe2 0x201a 0xac text [corrected] = Note the second hex code. Interestingly 0x201a is a Unicode code point containing a , character but I'm clueless how Tomcat got there ... Bye Christian PS: I have attached a JSP file for more multibyte samples ... -- Christian Mallwitz INTERSHOP Communications Germany Senior Software Engineerphone: +49 3641 894 334 post.jsp complete-charset-unicode-utf8.jsp - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
