[summary] reading xml from pipeline into a flow script
Jonathan's suggestion worked, so I thought I'd summarize the solution
back to the list as a demo javascript flow script.
function demo() {
print getXML(http://localhost:8080/cocoon/mypipeline.xml;);
}
function getXML(urlStr) {
//
// return output of a pipeline as an xml string (and/or dom)
// [NB. watch out for my app-specific parse settings below!]
//
var factory =
Packages.javax.xml.parsers.DocumentBuilderFactory.newInstance();
factory.setValidating(false);
// Prevent expansion of entity references
factory.setExpandEntityReferences(false);
// Configure it to ignore comments
factory.setIgnoringComments(true);
var document;
var isvalid = true;
try {
document = factory.newDocumentBuilder().parse(urlStr);
} catch (e) {
isvalid = false;
print(xml parse error: + e + \n);
}
var xmlStr;
if (isvalid) {
// Convert document to string
var format = new Packages.org.apache.xml.serialize.OutputFormat(document);
var strOut = new Packages.java.io.StringWriter();
var XMLSerial = new
Packages.org.apache.xml.serialize.XMLSerializer(strOut,format);
XMLSerial.serialize(document.getDocumentElement());
xmlStr = strOut.toString();
}
return xmlStr;
}

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?

Thanks. I was glad of any solution at midnight on saturday, but I'll
watch to see how the fom evolves as you advise. Thanks.

This will work but not with the upcoming Flow Object Model. You won't
have access to the environment any more. If you are interested in the
FOM you find a reference here:
http://wiki.cocoondev.org/Wiki.jsp?page=FOM (be aware that this is a
working document and may change!!!)
So currently the easiest way is
{
...
var uri = cocoon://blablabla;
var resolver = cocoon.componentManager.lookup(
Packages.org.apache.cocoon.environment.SourceResolver.ROLE );
var srce = resolver.resolveURI( uri );
cocoon.componentManager.release( resolver );
var dom =
Packages.org.apache.cocoon.components.source.SourceUtil.toDOM( srce );
...
}
which will probably change with FOM to
{
...
var uri = cocoon://blablabla;
var resolver = cocoon.getComponent(
Packages.org.apache.cocoon.environment.SourceResolver.ROLE );
var srce = resolver.resolveURI( uri );
// release of the component (not defined yet
var dom =
Packages.org.apache.cocoon.components.source.SourceUtil.toDOM( srce );
...
}
Hope this helps!

Re: Woody textareas?
Cocoon's form handling is (imho) it's weakest area at present although it is rapidly improving with the interplay between flow and xmlform. Unless your app is simple, I'd recommend not wasting time on the simple form validator and db actions. Pure xmlforms where you end up writing java code for each form is elegant but time consuming. I've not looked in detail at woody. However, I'd strongly recommend that you take a look at the petstore sample. This uses javascript as the interface to the persistence layer part of your model and (to my taste) a really easy to understand but flexible logic layer in a separate javascript file. The sample has switchable view layers that can be velocity/xslt/jxpath/jsomethingelse. The velocity vesion is very clean and easy to read (but there again, I used to be an assembler programmer!). Use is made of xmlform - with validation done in either schematron and/or javascript. Cheers Simon Luke Penca wrote: Are textareas implemented in Woody yet? I cannot find anything in the (oh so sparse) documentation. Furthermore, has anyone used Woody extensively yet? (I know, I know, it's alpha at this point but I need some serious forms handling.) Should I be considering Xforms instead? Who got some experience getting their hands bloodied with forms in Cocoon? I'm ever anxious to find out.

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. 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!

how to configure cocoon to spot sitemap changes without restarting

possible bug in pipeline/transformer?
I'm seeing some strange behaviour when I use an XSLT stylesheet
generated on the fly by cocoon. Unless I reference the generated xsl in
the pipeline before using it as a transformer src I get a null pointer
exception on the transformer (the one labelled DEBUG below). Hence the
pointless map:part hack below.
map:match pattern=bind-*.xsl
map:generate src=model/{1}.xml/
map:transform src=model/makebinder.xsl/
map:serialize type=xml/
/map:match
map:match pattern=*.html
map:aggregate element=doc
!-- HACK: I don't want this here but it makes the transform work!--
map:part src=cocoon:/bind-staff_model.xsl/
map:part src=model/staff_model.xml/
map:part src=xforms/{1}.xml/
/map:aggregate
map:transform src=model/selectmodels.xsl/
map:transform src=cocoon:/bind-staff_model.xsl label=DEBUG/
Is this a bug? I can't find anything about it in bugzilla or on the
list. Thoughts/suggestions welcomed.
There's nothing wrong with the stylesheet itself - if I save the xml it
produces as a file and then use that as the transform src it all works
fine without the hack.

Re: XMLForm data stored/retrieved via Session Transformer?
Ivelin Ivanov wrote: XMLForm currently supports JavaBeans, DOM and mixed models. You can look at the Feedback Wizard demo for example. I will look again, but it was not obvious to me how to pass a DOM model. How do you mean that people will be using forms without writing Java code. We can write another Action to take as parameter a file name with the XML model, however how you you handle the input data once submitted. How would you implement the logic for handling the input data? This has been requested before, but noone has suggested a better replacement for Java when it comes to writing general purpose logic. Schematron could still be used to do validation. XSLT could operate on the model instance (built from the request) to so simple logic. I agree Java is better for complex logic, but XSLT would be a nice halfway between the modular database actions approach and the full XML Forms + JB approach. I'll try and work my ideas up into a full example to show what I'm thinking of. Another idea might be to use the flow engine to do some of the validation/processing. Although I don't think this would scale well, it would be a practical entry point for people moving from clientside to serverside - they could make use of their javascript skills and then later move on to java.

[SUMMARY] problems generating input to sql transformer with stylesheet (a la Langham Ziegeler book)
Adding this line to the stylesheet fixes the bug. xsl:output method=text/ In fact the problem turned out to have absolutely nothing to do with the sql transformer; the problem was earlier in the pipeline but was masked because the xml piped into the transformer appeared okay when inspected using a view. However, although it serializes and displays in the browser, any attempt to transform the subsequent xml that comes out of the stylesheet creates an error. I only discovered this when I started shortening the pipeline and also found that if I cut+pasted the xml from the stylesheet transformation into a text file, it worked fine if loaded by a file generator and immediately piped into the sql transformer! I assume its a bug in one of cocoon's components. Go figure :-( Simon Simon Price wrote: Ah! That's good to know. I can't use Java 1.4.1 because of the old Oracle 8i JDBC driver I'm using but I will try running it under cocoon 2.0.3 to see if its a 2.1 bug. Thanks again.

Re: how to use a checkbox with DatabaseUpdateAction
Thanks Christian. I'll look into this. My fallback plan is to write a logicsheet in XSLT/ESQL to do the same as the DB actions but at a higher level. What I'm trying to end up with is an XForm-like way of writing (simple model) forms but without having to write any java. For many simple applications, this is all lots of people would need (I think). Cheers Simon Christian Haul wrote: On 23.Jul.2002 -- 09:36 PM, Simon Price wrote: Is it possible to get DatabaseUpdateAction to write, for example, 'Y' or 'N' into an SQL column according to whether a checkbox is checked/unchecked? You could have a default for this column of N - but since the parameter is not present (- null) the DatabaseUpdateAction will insert a NULL into that column. No luck. You could use DatabaseUpdateAction from the modular package (scratchpad in 2.0.3, trunk in 2.1-dev) and wrap this column with a default module. 2.1-dev has such a module (DefaultsMetaModule), while 2.0.3 does not. This is because the signature of InputModules has changed slightly and 2.0.3 is bug-fix only. It should be easy to backport a module from 2.1 to 2.0.3 as the basic difference is the use of the objectModel instead of Request.

SUMMARY: how to use a checkbox with DatabaseUpdateAction
I've come up with a code-free workaround for the problem.
Quick reminder of the problem: HTML checkboxes do not submit a request
value if unchecked and hence DatabaseUpdateAction writes NULL into the
corresponding column in the database. In Cocoon 2.03 there in no way of
overriding this effective NULL default.
What is more typically required is something like: when checked, write
Y; when unchecked, write N. By adding a hidden input field of the
same name as the checkbox input field to your HTML form you can force a
non-NULL default.
eg. my version of simple-page.xsl generates HTML for a checkbox as...
input type=checkbox name={@name} value=Y
xsl:if test=.='Y'
xsl:attribute name=checkedtrue/xsl:attribute
/xsl:if
/input
!-- default value for when checkbox is left unchecked --
input type=hidden name={@name} value=N/
When the box is checked, the Y is written, but when unchecked, the N is
written.
Cheers

[SUMMARY] how to use a checkbox with DatabaseUpdateAction
Take 2... this time with correct summary prefix in email title :-)))
---
I've come up with a code-free workaround for the problem.
Quick reminder of the problem: HTML checkboxes do not submit a request
value if unchecked and hence DatabaseUpdateAction writes NULL into the
corresponding column in the database. In Cocoon 2.03 there in no way of
overriding this effective NULL default.
What is more typically required is something like: when checked, write
Y; when unchecked, write N. By adding a hidden input field of the

Re: SUMMARY: how to use a checkbox with DatabaseUpdateAction
Doh! I worked out that DatabaseUpdateAction just took the first array item and in IE6 and NS6 this happens to be the same order as they occur in the form. I was assuming that this would be the case with all clients. Live and learn! I'll have to find a proper solution after next week but this kludge will let me make my UI review version deadline for next week ;-) Thanks Simon Christian Haul wrote: On 25.Jul.2002 -- 03:31 PM, Simon Price wrote: I've come up with a code-free workaround for the problem.

Sorry to disappoint you, but the above does not work reliably: If multiple fields with the same name exist, it completely depends on the client in what order they are sent. So, you get two values and when using the getAttributeValues() method, you'll get an array ['Y','N'] Chris. -- --- Simon Price Institute for Learning and Research Technology University of Bristol 8-10 Berkeley Square Bristol BS8 1HH United Kingdom Direct: +44 (0)7071 226 720 Office: +44 (0)117 928 7193 Fax: +44 (0)117 928 7112 [EMAIL PROTECTED] http://www.ilrt.bristol.ac.uk - 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]
how to use a checkbox with DatabaseUpdateAction
Is it possible to get DatabaseUpdateAction to write, for example, 'Y' or 'N' into an SQL column according to whether a checkbox is checked/unchecked? The problem is that only on (ie. checked) checkboxes submit a value, so is there an easy way to translate this into a Y/N value to go in the DB column. Apologies is this is well documented somewhere, but I can't find it. I had no problems getting form values from input/text and selections to work, but this one's less obvious (to a cocoon newbie like me anyway).
