Re: communicating between 2 diffrent sessions
Hi,
Is this right?
In Java API, I found some useful information.
There is one context per web application per Java Virtual Machine. (A web
application is a collection of servlets and content installed under a specific subset
of the server's URL namespace such as /catalog and possibly installed via a .war
file.)
I also test it with Tomcat 3.2.3.I create two webapps.one is 'test1',the other is
'test2'.In test1, there is a javabean with scope=application.All jsps in test1
can get the value of the javabean.But got nothing in test2.
If I am wrong, please info me.
%@ page contentType=text/html; charset=GBK %

Subject: Re: communicating between 2 diffrent sessions
The context is a container like a session, only that it's valid for the
lifetime of the tomcat process and is accessible by all webpages.
In JSP you refer to it as the application
You could say in your Servlet:
-
public class TestServlet extends HttpServlet {
ServletContext context = null;
public void init (ServletConfig config) {
context = config.getServletContext();
}
public void doPost (HttpServletRequest request, HttpServletResponse
response) {
String parameter = (String) context.getAttribute(parameter_name);
if (parameter==null) {
parameter = Some standard value for the parameter
context.setAttribute(parameter_name, parameter);
}
}
}
-
Now, in your JSP, you should be able to access the parameter as a bean with
scope = application
Hope there are no typos, and it helps, this could be one way to solve your
problem.

Subject: communicating between 2 diffrent sessions
Hello,
I have 2 apps (one in /webapps/myapp1-with jsp and other
webapps/root/myapp2-with servlets) on a jakarta-tomcat-3.3-m4 on a
win98 OS.
My problem is that I need parameters that are in session of myapp2 to
transmmit in session of myapp1.
Can I do that?
It is possible to set the same session for both apps?
Thanks!

Hello, Rodrigo, Does that mean that also the static pages (like for instance /examples/servlets/index.html) are served correctly by Apache?

Hello Rob: I'm using Apache 1.3.20 and the static pages work fine. I've disabled the cache just to make sure that the pages are being served correctly. However, I'm having a similar problem like yours with a different configuration. I will post a mail to the list with the problem description soon.

Re: IllegalStateException on jsp:include in simple jsp page
This simple tst.jsp page: !DOCTYPE HTML PUBLIC -//W3C//DTD HTML 4.0 Transitional//EN html head titleTst.jsp/title link rel=stylesheet type=text/css href=tst.css jsp:include page=tst.js flush=true / /head body h1Tst.jsp is OK!/h1 /body /html is producing an IllegalStateException on the inclusion of the tst.js file when using the current jakarta-tomcat-4.0 binary release. The same tst.jsp file works fine when using the jakarta-tomcat-3.2.3 release. I don't see that I have much control preventing the call to obtain the request output stream so how do I prevent this error, and is this valid behavior? The full exception is given below as well as the tst.css and tst.js files. The behavior is valid, but is easy to fix. Here, the JSP page uses a writer. Since the static page server is also a servlet, it can't use an output stream to output the data (you'll get that ISE if you call getOutputStream()). It will attempt to use the writer in that particular case, but only if the file being included is a text file (it's the case here, but there's no MIME type for .js). The test used is that the MIME type of the included file has to be starting with text. Adding the following mapping in your web.xml should make it work: mime-mapping extensionjs/extension mime-typetext/plain/mime-type /mime-mapping Remy

Tomcat+BAS 4.5 on different machine
Hi All I set up an environment which have Apache, Tomcat and BAS 4.5 (Borland Application server) working on the same machine but now I would like to have Apache and tomcat on one machine and BAS 4.5 Application Server installed on an other machine so I am wondering how to configure Tomcat and BAS 4.5 to have them working (talking) together if they are in two different machine. For now everything are on WIN2000 environement (for development) but will have to migrate everythingto UNIX (Production) I use Tomcat to run JSP and Servlet and BAS 4.5 to RUN EJB's (enterprise Java beans) Any help on that wuld be really appreciated.

FreeBSD mod_webapp

I got the source and build it, but there were couple of things I ported (stdint.h, dyld, etc.. everyone who tried mod_webapp FreeBSD will understand what I am talking about).

[TC4] mod_webapp.so compilation failure

apache/tomcat 4.0/gnu-linux setup question
Hey List, I'm trying to setup jakarta tomcat 4.0 for the first time and i'm trying to get some sort of virtual hosting deal going on that forwards connections from apache on port 80 to tomcat on port 8080 when a persons URL is entered. I currently have mod_webapp.so installed properly and included in httpd.conf. I haven't added any lines to my VirtualHost directives because I have a virtual host defined in server.xml, and I like the idea of being able to add new webapps using web.xml instead of defining a new one in httpd.conf every time. So below you will find the directory structure i'm trying to use and a few lines from my configuration files. Basically I just want to be able to type in a URL and get apache to hand off the request for servlets defined in web.xml and *.jsp files forwarded to tomcat 4.0. Possible maybe? # users web directory /websites/commaflex.com/public_html # users WEB-INF /websites/commaflex.com/public_html/WEB-INF/web.xml /websites/commaflex.com/public_html/WEB-INF/classes /websites/commaflex.com/public_html/WEB-INF/classes/HelloWorldExample.class /websites/commaflex.com/public_html/index.jsp # excerpt from server.xml Host name=www.commaflex.com debug=0 appBase=/websites/commaflex.com/public_html Context path= docBase= debug=0 reloadable=true/ /Host # excerpt from web.xml servlet servlet-nameHelloWorldExample/servlet-name servlet-classHelloWorldExample.class/servlet-class /servlet servlet-mapping servlet-nameHelloWorldExample/servlet-name url-pattern/hello/url-pattern /servlet-mapping Sincerely, Brendon Maragia I hope we shall crush in its birth the aristocracy of our monied corporations which dare already to challenge our government to a trial of strength, and bid defiance to the laws our country --Thomas Jefferson
