RE: protecting a non-jsp file from accessing
I would include the file in the same place as the class file (in the app-root/web-inf/classes/...)- then you can use something like yourclassname.class.getResourceAsStream(sub folder relative to class's package/db.cfg); Then you can read the configuration properties from that stream (Dont forget to close it after reading the contents).

Using a default mapping of / results in failure to gain access to resources under my servlet directory. I think I have a fairly standard set-up of tomcat 4.0.1 on win2k. Within C:\jakarta-tomcat-4.0.1\webapps I have a directory structure like this: myapp styles global.css WEB_INF web.xml lib [jar files] web.xml defines a servlet whose output includes a reference to http://mysite.com/myapp/styles/global.css If I set my servlet mapping up like this: servlet-mapping servlet-namemyapp/servlet-name url-pattern//url-pattern /servlet-mapping then the stylesheet cannot be loaded when the user surfs to http://mysite.com/myapp/ Alternatively if I set up my mapping like this: servlet-mapping servlet-namemyapp/servlet-name url-pattern/foo/*/url-pattern /servlet-mapping then the stylesheet can be located, but the user must surf to http://mysite.com/myapp/foo/ How can I configure tomcat or structure my directories so that a user can surf to http://mysite.com/myapp/ and also successfully access the stylesheet? Note that the above is a contrived example. The real servlet includes many other resources in the myapp directory to which the servlet refers. Any advice would be most welcome.

RE: Illegal State Exception
You are doing something like res.getOutputStream().write(data); twice within the same request. This could be for several reasons and it general occurs when you include a page in your response and then try to use the above - you can do a response.isCommited() to check the state of the response. -Original Message- From: Justin Rowles [mailto:[EMAIL PROTECTED]] Sent: Wednesday, December 19, 2001 10:03 AM To: 'Tomcat Users List' Subject: Illegal State Exception At intervals I get this error (or very similar).

RE: JSP translation's problem...
Probably JRun's implmentation of the ServletResponse.getWriter() and
JspWriter are the same where as with tomcat the 2 are different entities
combined when the response is sent to the client.
Whats your code like ? technically using the out should be the same as doing
a
%=SOME DATA%
Should be equivilant to
% out.println(Some data); %
which is exactly the syntax you should use in your bean
class formmngtbean {
public void getPage(HttpServletRequest req,JspWriter out) {
out.println(Some data);
}
}

Thank you S for your response, but i can't yet make it work... a
curiosity:
why i have this problem (within tomcat) and when i run this web app. with
IIS/Jrun work perfectly ? I mean, IIS/Jrun translate the jsp page in the
correct
order, putting the HTML code generated by my bean exactly where i call the
bean,
not in the top of the HTML page, like happens with tomcat.
Really, i don't understand...

Detecting server name and port
I have a web application which sends out email reminders to members in a database when certian tasks are slipping- This all works great however I would like the application to be smart enough to know which server and port it is installed in so when generating a message it can include a link back to the particular task. What I have currently done is include an init-param tag with this information and it works but then it isnt server independent. I have also explored the possibility of getting the information from HttpServletRequest (which also works) but I'd like the timer function not to depend on someone actually requesting a page. Is there any other methods to get the server name and port ?

Creating Crystal reports from XML generating servlets
Title: Creating Crystal reports from XML generating servlets Informational post I finally had success using the new crystal reports Version 8.5 to generate a report from a servlet. As long as Seagate doesnt change anything we now have ultimate control over the data that crystal report's displays all without a single line of VBScript. There are a few gotchas though.. 1) the XML encoding method MUST be ?xml version=1.0 encoding=UTF-16 ? using ?xml version=1.0 encoding=UTF-8 ? will NOT work. You can set this up with your transformer by transformer.setOutputProperty(javax.xml.transform.OutputKeys.ENCODING,UTF-16); 2) you need to map your servlet with a .xml extension. in your web.xml add a servlet-mapping servlet-mapping servlet-name MyServlet /servlet-name url-pattern /MyServlet.xml /url-pattern /servlet-mapping Crystal reports automatically expects an xml extension. However when it prompts you for the table name you can send parameters like MyServlet?report_data_type=4 and these parameters will be recieved by the server. 3) Set the table hints and row hints as specified by crystal reports

RE: session timeout handling
Title: RE: session timeout handling Timeout will not send anyone anywhere. When the session expires it cleans up all the objects in the session's attributes. If the objects are of type HttpSessionBindingListener then an event is thrown against them. The best way to handle timed out users is to attach an object of HttpSessionBindingListener to their session, When that object recieves the unbound event do whatever is needed to be done to clean up. Note - (I got burned on this) at the unbound event the session object no longer references any attributes (or maybe it is just some) so the object of the above type should have enough intelligence in it to handle the actions you want to perform at the end. for example you had a session attribute storing the logged in user name, dont expect that attribute to be available after the unbound event. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Friday, June 22, 2001 3:51 PM To: [EMAIL PROTECTED] Subject: session timeout handling When a Tomcat session times out does it send you to a preset error page?

What is the best way to handle timed out users? Depends. Do you have a security concern(if so you should be implementing Realms of some sort which manage the session timeout for you)? Are you requiring something to exist in the session for certain portions of your app? ...
