[Offtopic] JDBC
Hi all, Has anyone here ever had trouble with a connection request to an ODBC source through the JDBC<->ODBC bridge (driver: sun.jdbc.odbc.JdbcOdbcDriver) failing with an error "Login failed for user '\'"? I'm getting this whenever I try to connect to the DB, despite the fact that username/password being sent through are correct (and are not \!). Any ideas/suggestions would be gratefully received.

Re: Apache and PWS (Maybe OT)
This is possible, though it'll take a little buggering about on your part. You'll have more luck asking a question like this on an Apache (or PWS) list: I don't know about PWS, but for Apache you need to be looking at the idea of virtual hosts -- there's a load of good docs/mailing list archives available from http://www..apache.org Also, you won't be able to have both of them running on the same port on the same machine (unless you have multiple IP addresses), so you'll have to set one of them up to use something other than the default port 80. That'll mean you have to address it as e.g http://pws:8080/webpages -- not sure if there's any way around this, though I would be somewhat surprised if there is. You'll probably need to be taking a look at the hosts configuration file to set up your local aliases -- not sure where this is in Windows. Probably somewhere in c:\windows or wherever. -Original Message- From: A mailing list about Java Server Pages specification and reference [mailto:[EMAIL PROTECTED]]On Behalf Of Theo Starr Sent: Friday, November 02, 2001 3:37 AM To: [EMAIL PROTECTED] Subject: Apache and PWS (Maybe OT) Hi Everyone I know it is possible to have Apache and PWS running on the same machine but I find they clash where they are both running at the same time and you use "localhost" Is it possible to give one or both a different address such as "apache" and "pws" where both are exclusive addresses? such as http://apache/webpages and http://pws/webpages Has anyone tried this??

Passing parameters to includes
Hi all, I was wondering how other people approach the problem of passing parameters to include files (or even if this is really something that it's a good idea to do...). For example, say I want to specify some button text for an included file, I may want pass a parameter called "buttontext" with the value "Hello". The way I've been approaching this so far is to encode the parameters as a query string on the include URL, e.g. but this doesn't really scale up to anything more than simple textual arguments. I could add stuff to the session or context, allowing me to use more complex objects, but I don't want to be creating a load of interdependencies as far as attribute naming etc. is concerned between an include file and the file including it. Ideally, I'd like to just be able to parameterise the include as one would a method. Any suggestions? Chris Tucker === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Re: Passing parameters to includes
Thanks to everyone for the replies. I'm thinking that my best approach (as yet untested) will probably be to combine string parameter passing (using jsp:param) and request attributes: i.e. use string parameters to identify the name of the request attribute, and an object in that request attribute to store my actual data. That way I can keep the namespaces of each file completely separated but still refer to objects between them. e.g. <%-- set parameters --%> <%-- set parameters --%> Now I just have to work out how well it handles sending multiple values in like that, and see if maybe I need to just use one and wrap it up in a Vector or whatever. Anyway, thanks again.

For example. if a specific include page has a button with the text "hello" and that changes only when business requirements dictate it. You can actually just put it into your web.xml file as an init parameter. You see this alot with webaddresses. For example a JSP page that is included as a footer file may have a "Questions and Comments contact the webmaster" where the webmaster is actually a link that says <.mailto:[EMAIL PROTECTED]> (the . was put to prevent this from showing in HTML) That web address is usually placed as a web.xml init param called webmaster (or whatever). But if the text must change dynamically depending on who is accessing the page. It may be better to have it as a database value stored and keyed by the customers id. Another approach is just do it the way that you are now. But that may cause a problem as the url has a length limitation and depending on how many fields you are setting this may cause some problems. Security is of course an issue with that method as well. Any user can tell that you are setting up fields through the URL and can easily just pass a new URL to display what he/she wants to display. Of course there are more solutions as well but I think these 2 are the main solutions if you are not hardcoding values. -Tim -----Original Message- From: Chris Tucker [mailto:[EMAIL PROTECTED]] Sent: Friday, November 09, 2001 2:14 PM To: [EMAIL PROTECTED] Subject: Passing parameters to includes Hi all, I was wondering how other people approach the problem of passing parameters to include files (or even if this is really something that it's a good idea to do...).

Re: Please help! Recursive loop in JSP
Easiest way to do this is just to set up a recursive method call to go through each level in the tree. Effectively you're just doing a tree traversal, and can apply all the standard algorithms to this: your nodes are each of the people, and can be picked out using an appropriate SQL query (e.g. SELECT name FROM People WHERE parent = 4). You can build this query for each recursive call, modifying the WHERE clause appropriately. The problem with this approach is that you can end up with a shedload of database connections going on, and if the tree is deep or broad you'll suffer from a hell of a slowdown related to having to initiate a query for every single person. You can optimise this by using more complicated WHERE clauses on your SQL to select everyone at a given level meeting the appropriate criteria, thereby limiting the number of recursive calls to h (where h is the height of the tree). You may also want to maintain a list of all the nodes you have already processed to check for the a mistake in the data that leads to a cyclic dependency (e.g. mary is johns mother, mary is johns daughter). Your data shouldn't have these in it, but it's a good idea to check to make sure or you risk crashing the server in a big ol' recursive loop. There are further ways to optimise the queries (such as unrolling your recursion into a loop), but unless this is going to be a real heavy load situation you're likely to be better off going for code readibility and maintainability. As far as doing this in JSP is concerned, you should put the code to do the actual recursive search into a bean and simply format its output with appropriate JSP.

Re: Login Authentication against database...
I'm assuming that
you are actually entering that while() loop (i.e. data is coming back from the
query). In that case, it seems likely that a SQLException is being thrown
by either myResultSet.getString("UserLoginId") or
myResultSet.getString("UserPassword"). The most likely cause of this
is that you've got the wrong name for a column (i.e. UserLoginId or UserPassword
does not exist in the results of the query you execute to get
myResultSet). Check your column names. Also, I assume you're going
to be catching SQLException's somewhere nearby: output the error message, it's
generally quite informative.

Re: how to embed Javascript in Jsp?
There was a long discussion on this a while ago in this list which went into
some detail about this whole issue. In fact, reviewing it, you were
involved in the discussion! Basically, your JavaScript has to go, in source
form, to the browser (i.e. the client) because it is a client-side
interpreted language. There is absolutely no way you can prevent someone
with a little guile from reading your JavaScript -- you can make it harder
by using tags etc., but the script is
still sent to the client. You can look for an obfuscator to make it harder
for people to understand the code, but it'll still be there. You can't use
JavaScript on the server side to execute any form of dynamic client side
activity. Period.
