Best practices for validating request params?
Hi guys, I was wondering what the best way is to validate request parameters. I have a few questions: 1.) What is the best way to validate the *existence* of all expected request params (both for simple queries and for posting form data)? By this, I mean I'd ideally like to notify the client if any request param wasn't sent. I was thinking I could write a dedicated action to do this validation before another action extracts/formats the values. 2.) Do you think it is even a good practice to take the time/effort/cpu power to validate that all expected request params were sent and notify the client if they were not? Otherwise, my action that extracts/formats the values would just end up throwing things like NullPointerExceptions, NumberFormatExceptions, etc. when it tries to extract/format the values. This doesn't seem very elegant at all to me, even if I do wrap them in ProcessingExceptions before throwing them. One other reason I don't want to throw these seemingly odd and random exceptions is because they'll just give a stack trace that says my code failed on Line XXX. On my team we have another development group that is working on buiding the actual XHTML webpages and making sure they work with the backend. 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!

simple question
Hi guys, I'm trying to use the xsl:output element in my logicsheet (for an accompanying XSP) to remove the XML declaration (the ?xml version=1.0?) from my output doc. I just put xsl:output method=xml omit-xml-declaration=yes/ right inside my opening xsl:stylesheet tag. However, in the processing of the stylesheet itself, this ProcessingException is thrown: org.apache.cocoon.ProcessingException: Exception during processing of file:/jakarta-tomcat-4.1.12/webapps/cocoon/mysite/stylesheets/my_logicsheet.xsl: java.io.UTFDataFormatException: invalid byte 1 of 1-byte UTF-8 sequence (0xa0) I also tried adding the 'encoding=UTF-8' attribute/value to the xsl:output tag, but I got the same error. Can anyone shed some light on this for me?

Jumping within sitemap?
Hi guys, I'm wondering if it's possible to jump from one place in the sitemap to another. I made up the following code, but it's basically what I'm aiming to do: map:match pattern=checkout map:act type=is-logged-in/ !-- Customer is logged in, so proceed to first checkout step -- map:jump jumpto=customer-info-entry/ /map:act !-- Customer isn't logged in, so jump to login page. -- map:jump jumpto=customer-login/ /map:match map:match pattern=customer-info-entry map:generate src=customerInfoEntry.xsp/ map:transform src=someTransform.xsl/ map:serialize type=html/ /map:match map:match pattern=customer-login map:read src=customerLogin.html/ /map:match It's like calling a function/method in a programming language, and it thus supports reuse of factored out code. Does it make sense? Please let me know how we can do it! :-) Thanks, Sonny __ Do you Yahoo!? Yahoo!

Sessions stomping on xsp:init-page!!
Hi guys, I found that if I put the xmlns:xsp-session=http://apache.org/xsp/session/2.0; namespace in any XSP document, then xsp-init-page tag isn't processed. Thus, all the variables I declare/initialize in xsp-init-page (which should go at the start of generate()) are nonexistent, which obviously causes compilation problems. The only thing that gets put at the start of the generate method is: Session session = request.getSession(true);. Anybody know how to keep this from happening??

RE: Can anybody solve this?
Artur, Somehow I couldn't move the the productId declaration initialization before the Product tag because this would move it to class level and 1.) the xsp-request:get-parameter tag must be used within the root element of the generated document (for some reason) and 2.) I get a NullPointerException when I try to use request.getParameter at the class level. I have *very* little knowledge of the request object and its XML logicsheet wrapper (I'm a newbie :-), so I unfortunately can't shed any light on the exact reasons for these things.

Possible with XSPs?
Hi guys, Is it possible to access request parameters from within an XSP or logicsheet? For example, when I go to http://localhost:8080/cocoon/test?param=12345678 I'd like to use the value of param in my XSP or logicsheet as a basis for calling Java functions. In my pipeline, I currently just have the XSP as the generator and 1 XSL stylesheet to output to HTML. I think I could introduce another XSL stylesheet before this one which has use-request-paramters set to true and get the param that way, but it seems like it'd be slower to do 2 transforms with 2 separate stylesheets rather than 1 transform with 1 stylesheet.

Also, here's the sitemap tag in $COCOON_HOME/WEB-INF/cocoon.xconf: sitemap check-reload=yes class=org.apache.cocoon.sitemap.SitemapManager file=sitemap.xmap logger=sitemap reload-method=synchron/ *The check-reload and reload-methods look like what they should be for the sitemap to be reloaded upon being changed and before serving any new requests. *I also tried stopping and restarting Tomcat. *I both flushed and turn off Konqueror's cache as well. Could it have something to do with Cocoon's cache itself?? I would be very happy if one of you could take the time to point me in the right direction.

Re: Stuck on Hello World, with non-FAQ Problem
Hi, I should have mentioned that sitemap.xmap is in $COCOON_HOME, where it is supposed to be from what I've read. I tried your suggestion, and got the same error. Btw, can anyone tell me why there are MULTIPLE sitemap.xmap files in $COCOON_HOME subdirectories? I thought there was only supposed to be the one in $COCOON_HOME. If anyone can help me out with my original Hello World question, I would REALLY appreciate it..I want to get this to work sooo much. Thanks again. :-) Sonny --- Kjetil Kjernsmo [EMAIL PROTECTED] wrote: On Monday 07 October 2002 19:24, Sonny Sukumar wrote: The error: The requested URI /cocoon/helloworld was not found.

Re: Stuck on Hello World, with non-FAQ Problem
Sure, here's a quick copy and paste of $COCOON_HOME (same thing as $TOMCAT_HOME/webapps/cocoon): cocoon.xconf.moved i18n resources sitemap.xmap.bak tutorial docs logicsheets samples stylesheets WEB-INF documentationMETA-INF searchsub welcome helloworld2html.xsl mountsitebuilder sunspotdemo helloworld.xml protectedsitemap.xmap templates The problem *is* a Cocoon problem. The Tomcat servlet engine works just fine and Cocoon runs on it, but I can't get this Hello World example to work. I also don't understand why the other Cocoon pages still come up after I deleted ALL the other stuff inside the map:pipelines tag other than my map:pipeline for the Hello World example that generates from helloworld.xml, transforms with helloworld2html.xsl and serializes the output.

RE: Stuck on Hello World, with non-FAQ Problem
On a fresh Tomcat (4.1.12) installation I copied the file cocoon.war (this is Cocoon 2.0.3) into the $TOMCAT_HOME/webapps directory. I then started Tomcat using $TOMCAT_HOME/bin/startup.sh, navigated to http://localhost:8080/cocoon and Tomcat expanded cocoon.war into $TOMCAT_HOME/webapps/cocoon, started the Cocoon servlet, and displayed the Cocoon intro page. As I said before, to do this Hello World example, I modified the map:pipelines section of sitemap.xmap to just contain the map:pipeline for the Hello World example. Actually, first I tried just adding the Hello World pipeline...when that didn't work I deleted the rest. It still doesn't work. And I'm not sure how Tomcat could be running some other Cocoon instance either. But I am obviously missing something somewhere. And thanks for the info on the parent-child sitemaps..I guess I'll get to that later, once I get this to work. :-) --- Hunsberger, Peter [EMAIL PROTECTED] wrote: I also don't understand why the other Cocoon pages still come up after I deleted ALL the other stuff inside the map:pipelines tag other than my map:pipeline for the Hello World example that generates from helloworld.xml, transforms with helloworld2html.xsl and serializes the output. That tends to suggest that the copy of Cocoon you are modifying isn't the same one that Tomcat is running... How are you deploying Cocoon (expanding the EAR manually and copying?)? BTW, to answer another question you had earlier, the reason you see sitemap.xconf in multiple directories is that a parent sitemap can mount sub-sitemaps. It's a parent child relationship from the main sitemap... - Please check that your question has not already been answered in the FAQ before posting. http://xml.apache.org/cocoon/faq/index.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] _ Conserve wilderness with a click (free!) and get your own EcologyFund.net email (free!) at http://www.ecologyfund.com. _ Select your own custom email address for FREE!

Re: Stuck on Hello World, with non-FAQ Problem
I switched treeprocessor by commenting out one sitemap tag and uncommenting the other one in cocoon.xconf. Btw, what is stored in Tomcat's work directory? This might sound like a dumb question to you, but I'm still on Hello World. :-) Likewise, I haven't done anything with error handling, so if you feel this is something important that I should do here and now to diagnose the problem, I humbly ask for a small explanation so I can understand what's going on. For example, what XML source does the error2html.xsl file in your sample code operate on? Lastly, I know for a fact I'm editing sitemap.xmap and not the sitemap.xmap.bak file I created to simply backup the original sitemap.xmap file before I started playing around with it. But it is good of you to point out. :-) Sonny --- Steven Noels [EMAIL PROTECTED] wrote: Sonny Sukumar wrote: The problem *is* a Cocoon problem.

It does make sense and indeed it seems like your changed sitemap isn't loaded. Did you clean out the 'work' directory of Tomcat when restarting - not that this should be the problem, but one never knows. Also, adding a error-handling section in your pipeline configuration might provide you with some useful info: ... map:handle-errors map:transform src=stylesheets/error2html.xsl/ map:serialize/ /map:handle-errors /map:pipeline Another idea: switching to the (interpreting instead of compiling) treeprocessor, by swapping it with the normal sitemap engine configation with sitemap logger=sitemap/ Oh, BTW, it's not that you are editing the wrong sitemap file (.bak)? /Steven -- Steven Noelshttp://outerthought.org/ Outerthought - Open Source, Java XML Competence Support Center [EMAIL PROTECTED] [EMAIL PROTECTED] - Please check that your question has not already been answered in the FAQ before posting. http://xml.apache.org/cocoon/faq/index.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] _ Conserve wilderness with a click (free!) and get your own EcologyFund.net email (free!) at http://www.ecologyfund.com. _ Select your own custom email address for FREE!

Re: Stuck on Hello World, with non-FAQ Problem
I cleared out error.log and accessed http://localhost:8080/cocoon/helloworld again and there's no errors that are logged. The page just comes up blank. When I click on View Source, the document source is COMPLETELY empty. Should I be using something other than serialize/?

This started happening after switching the sitemap tag, and this behavior is still there after deleting the contents of $TOMCAT_HOME/work. I guess this is a step forward though. Any idea why I could be getting a blank page? If not, then I guess I'll have try that error handling stuff eh?

Re: Stuck on Hello World, with non-FAQ Problem
Man, Steven, thanks for pointing that out--the Hello World example works now. The really weird thing is that I *did* check that quite a few times and fixed the missing ? mark before. However, I had made a backup copy of the helloworld.xml file so that I could delete my whole cocoon directory and reinstall cocoon from scratch (I thought I might have messed up the installation somehow). So I guess the backed up helloworld.xml file still had the missing ? and that's been a major culprit here. Sigh Also weird: Remember that I kept getting the error about cocoon/helloworld being an unknown URI? That error has mysteriously gone away...could it have been cleaning out the $TOMCAT_HOME/work directory that did it?? In any case, the example finally works!! Hooraaay!!! And it was supposed to be a trivial example too. :-) Go get some sleep--you have earned it. :-) Thanks!

I just copied the example straight from the book. Damn, my bad. So finally, I copied your code into files and fed that through Cocoon. Hm... org.xml.sax.SAXParseException: a pseudo attribute name is expected on my error page and in my logs... What could this be...? Load up your helloworld.xml in an XML editor, press validate and tada, typo found: ?xml version=1.0? ^ Yup, that stupid - didn't had anything to do with Cocoon. Do you have your error page up running now? The error message isn't particularly helpful (plain wrong in this case), but at least you get a feeling where to look at.

*Bizarre* Sitemap Problem
Hi guys, I am new to Cocoon, but I have read the FAQ and tried searching some archives as well as on Google, and haven't found the solution to this. Still, I am *really* sorry if this has been touched on before. Anyhow, onto the problem. I'm following along in the book Cocoon: Building XML Applications and trying to get the Hello World example to work. For ultra simplicity I modified sitemap.xmap so that the map:pipelines section is ONLY the following (after backing up the original sitemap.xmap, of course): map:pipelines map:pipeline map:match pattern=helloworld map:generate src=helloworld.xml/ map:transform src=helloworld2html.xsl/ map:serialize/ /map:match /map:pipeline /map:pipelines What's strange is that even after stopping and restarting Tomcat, when I go to http://localhost:8080/cocoon, the original Cocoon welcome page comes up that says something like Congratulations, you got me running. I flushed the cache in Konqueror and turned off its cache as well. Also, here's the sitemap tag in $COCOON_HOME/WEB-INF/cocoon.xconf: sitemap check-reload=yes class=org.apache.cocoon.sitemap.SitemapManager file=sitemap.xmap logger=sitemap reload-method=synchron/ The check-reload and reload-methods look like what they should be for the sitemap to be reloaded upon being changed and before serving any new requests. Ok, now here's the contents of the helloworld.xml file: ?xml version=1.0 document textHello World/text /document And of the helloworld2html.xsl file: ?xml version=1.0? xsl:stylesheet version=1.0 xmlns:xsl=http://www.w3.org/1999/XSL/Transform; xsl:template match=document html body h1xsl:value-of select=text//h1 /body /html /xsl:template /xsl:stylesheet Btw, both of these files are in $COCOON_HOME. Here is the error I get when I try to load http://localhost:8080/cocoon/helloworld: The requested URI /cocoon/helloworld was not found. There is no stacktrace given. So..with the new sitemap it *can't* map the URI helloworld and yet it can still find the files for http://localhost:8080/cocoon. This is really baffling me. Lastly, here's my version info: Cocoon 2.0.3 (latest stable release, obtained in binary form meant for JDK 1.4, which I have) Tomcat 4.1.12 (just obtained about a week ago in binary form) JDK: 1.4 OS: Redhat 7.3 I would be very happy if one of you could take the time to point me in the right direction. I'm a newbie, I know, but I'd like to become the next happy Cocoon user.
