Re: Best practices for validating request params?
You may want to take a look at the (from my dodgy memory) req-params action which does a simple existential check on request parameters. There's an example of its use in the modular database sample code's sitemap. Cheers Simon Sonny Sukumar wrote: Hi guys, I was wondering what the best way is to validate request parameters.

So these sorts of exceptions and stack traces won't help them at all to figure out what went wrong. If I notify them they forgot a param, they can say "Oh , I forgot to pass the XYZ param--that's why it's failing" and fix their XHTML code in short order. I'm interested to hear all of your thoughts!

RE: reading xml from pipeline into a flow script
Title: RE: reading xml from pipeline into a flow script
One simple way of accomplishing this is to simply, define pipeline to generate, transform, and serialize the xml. Then, in the flowscript, simply use the jaxp dom api to load the generated xml:
flow() {
var document = Packages.javax.xml.parsers.DocumentBuilderFactory.newInstance().newDocumentBuilder().build(http://uri-to-xml-file);
...
document.getDocumentElement();
// it is now a dom
}

Subject: reading xml from pipeline into a flow script
From within a flow script, I would like to read (or pass in) xml
generated by a series of pipeline xslt transformations.
Please could someone give me a pointer on how to do this?

RE: add user to unix
With Runtime.exec() but you need to read up heavily on it's use and/or ask about it on a more appropriate general java list or forum. I can tell you quickly that anytime you need to use exec() you should look into a threaded approach to handle parsing the standard error and standard out streams of your native process or you risk a hung jvm.

add user to unix
hello experts, i have a small applikation where the users can log in in to a portalpage (mysql-database), if they are not in the database they can create a user account (user,pass). what i want is when they create a useraccount, that a user be automatically created also under unix to a usergroup which have less priviliges, this allow them to connect the workstation by using telnet. first i thought this is impossible to do, but i read some postings in other forums and there are 3 possibilities: 1- when a user create a user-account: a java class create a file with user and pass and a cronjob look everytime to the file if there are new user odr not, if yes so he can add them 2- a java class which add the user under unix 3- a java class which calls a shell script is there any one who can tell me how i can realise this, i think the most simply is possibility 3, but how i can do that ? thanx Sliman - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Okay, so you need to uncompress it into XML and pass that into the SVG2JPG serializer. There's two ways to do that, either with a zip generator (I think there's an example of one in the Langham & Ziegler Cocoon book), or using the Jar protocol (see http://wiki.cocoondev.org/Wiki.jsp?page=JarProtocolExample). Both should extract your zipped SVG ready for converting to JPG. Hope that helps. Regards, Upayavira - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Apache 2.0.43 - Tomcat 4.1 - Cocoon 2.0.4 problem
Hi, I've setup an Apache / Tomcat / Cocoon integrated configuration. Fortunately the Apache / Tomcat part works pretty well, but I'm facing problems with the Cocoon part...I think it's redirection problem as my servlets are served well, but when I try to access a .xml file it simply shows me the text and not the result... here's my mod_jk.conf file, look at the /cocoon part and tell me if something's wrong please! any idea? thanks !

Javascript within XSP-Actions?
Hi all!
Does anybody know if I can use javascript for writing custom xsp actions?
What about the configuration?
Thanks for every help.
Markus
I tried this but it doesn't work:
http://localhost"/>
http://localhost:8081"/>
My xsp action page:
http://apache.org/xsp";
xmlns:xsp-action="http://apache.org/cocoon/action/1.0";
xmlns:matrix="http://schema.rheinland.net/matrix/matrix.htm";>
if (1==1) { test = "test"; }
else { test = "false"; }
I know that I can use javascript in xsp generators. That works fine.

Thanks for you reply, but how do I generate the source ? The file generator only seems to accept uncompressed svg.
