learning filters
I have been learning about servlet programming from Core Servlets. I like this book. But, since subscribing to this list, I have seen mention of filters. In a message from Yoav Shapira I was recommended to use filters to validate form data before passing it to a servlet. This seems to me a cleaner means of doing it, as opposed to putting form-validation code in the servlet. However, Core Servlets does not describe how to use filters (that I know of). Is there a reference for this technique somewhere, or is it a generic term for a servlet that intercepts, acts upon, and passes along data ? If it is the latter then I can figure it out from using getDispatcher().forward() etc but if it is a specific technique then where can I learn more? My Tomcat container is v. 4.0.6.

I may be simplistic but it seems to me that this would be a pretty fundamental ability for a standalone server and the thougth is just mindblowing that theJVM does not offer something similar. I find that hard to believe. Could not a solution be implemented like the Apache one, where the work of Tomcat (the JVM itself) is run by a non-privileged user, but it is connected to Port 80 by a process running as root?

hiding servlet URLs in JSPs
Hi, simple question (I hope): Does it really matter if someone can see the naked path to a servlet in the action attribute of an HTML form tag? I mean, if I have this form: form method=POST action=./servlet/SomeServlet !-- some input tags go here -- /form anyone can see the URL to my servlet and attempt to send it data directly. At first I thought that this was a security problem and that I should obfuscate the path to the servlet somehow, but on second thought it strikes me that this is no different than someone seeing the path to a CGI script in a form either.

We also need to remember that Tomcat does *not* scan the output your servlet or JSP page creates, and modifies the hyperlinks. If you do not call encodeURL() or encodeRedirectURL() yourself when creating the output, URL rewriting will never occur (and your app will require the client to support cookies if it uses sessions). A style question in this regard -- is the general practice for this: 1. To use a unique variable for each URL that needs to be encoded 2. To put all URLs into a list/array, then refer to them by their key in the page 3. To use a single variable name and just call encodeURL immediately before the point where the name is used, then echo the variable name to the browser 4.

I cant use one way hash as I cant use them further. what mechanism should I follow in this case? Have you considered LDAP? I haven't used it myself but it might be a better solution if you have to store a variety of user information that will be used in more than one context. Also, for the login case should I bother about encryption in the login form? Can I just use input type=password/ and rely on the brower? What are the pros and cons for this? If you see yahoo login, they generate md5 using javascript on the client side itself - is this really necessary? Generating the md5 on the client side doesn't really do too much, since if I know the MD5 then basically I know the password. I just can't type it into Yahoo's UI since then *that* will get MD5'd and it will change the value sent. (Of course, I could use Mozilla and disable the JavaScript that does this... or write my own page... etc.) If you use SSL then you don't need to do the JavaScript trick -- the passwords will be sent over the wire encrypted. But if you can't or don't want to use SSL, then just remember that it is SUPER easy to listen in on HTTP connections and watch the data go back and forth. There's dozens of scripts that basically do this and hunt down likely passwords. So you want to implement *some* level of encryption unless everything you're doing is within a secure environment like behind a corporate firewall (note the quotes, that indicates a level of facetiousness).

RE: newbie Q
Hi John, Thanks for the suggestion, but... I can't find it. Creating a Context entry is introduced but not really explained. The paragraph you mention is this: * Add a Context entry in the $CATALINA_HOME/conf/server.xml configuration file. This approach is described briefly below, and allows you to position the document root of your web application at some point other than the $CATALINA_HOME/webapps/ directory. You will need to restart Tomcat to have changes in this configuration file take effect. See the administrator documentation (TODO: hyperlink) for more information on configuring new Contexts in this way. I seem to be missing part of the docs. I would copy the one for examples webapp except that this is a very big Context node with a lot of details that I don't understand. Is the Administrators Guide available online somewhere?

You can also use server.xml's entries for the /examples directory/app as an example.

(Though I did create the webapp along the guidelines provided in the Application Developer's Guide, so that should be all set once I can get Tomcat to recognize that there is a new webapp there.) If anyone can help me with this, that'd be much appreciated (CC me as I am a digester), thank you.

So the directories you talk of are not yet present, presumably I create them at my leisure? What about ROOT? Why when I create webapps/mydir/myfile.jsp and load it into the browser is it not accessible? (404) Must I define a WEB-INF for each app under webapps? What must it contain? Thank you E. yes, each webapp has its own web.xml, you can use that among other things to define your servlets, taglibs, resource-refs. unjared classes go into /WEB-INF/classes directory, jars go into /WEB-INF/lib How long a web.xml can be depends on how many things you wish to put in there. I think the tomcat doc has a section on best practices deployment. It *should* come with your installation of tomcat. Enok Strine wrote: Hi folks, I have installed TC 4.1 and have it apprently installed correctly. Can anyone tell me the significance of the WEB-INF dir please? Also, must everything run under webapps/root/..? I am presuming WEB-INF holds configuration / class libraries for each app? Yet there is a single web.xml, file 6 lines in length?

RE: newbie Q
Whoops. I have the 4.0 docs on my host's server. That is what I was looking at. There are a lot more docs on the site you linked to. Are most of these applicable to 4.0, or is this for the most part 4.1 references? Thanks for the pointer, John.

making webapps without write access to $CATALINA_HOME
Hello, I have an account on my friend's Linux box, and he installed Tomcat 4.0.6 so that I could get some hands-on practice with servlet and JSP development. I was wondering if I will need to have write access to the $CATALINA_HOME subdirectories or whether there is a way to configure Tomcat to allow me to use my ~/public_html directory. If there is a HOWTO on this that I missed, I apologize -- please forward the link. ;) Erik -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
