Re: I'm confused about XSP , variables and session
On 29.Jun.2001 -- 12:21 PM, [EMAIL PROTECTED] wrote: For instance , I have a XSP logicsheet that declares: String person = request.getParameter(person); I then use this variable in a custom XSP tag library that is declared in the namespace of the XSP logicsheet. Is this possible because the person variable is static? Also, In my XSP tag library that I created, I have instantiated several variables: private String sPrefix; private String sFirstName; private String sLastName; private String sMiddleName; These variables are behaving like static variables. Every session on the webserver will be looking at the same variable in the tag library. I wanted to use tag library because I really like the notion of separating content and logic and tag library made this very easy by just dropping in dynamic data place holders in your XML. But if every session is looking at one static variable in my tag library, then I can't use tag libraries the way I want. I was hoping somebody could explain the scope of variables declared in XSP taglibs versus variables declared in logicsheets. I basically want variables that persist only in a specific session. Think of logicsheets aka TagLibs as macros -- that's what they are. They are no functions to call. Tags on your XSP get *replaced* by the contents of the tag definition in your logicsheet (this is not 100% accurate since it is possible to do some simple programming e.g. xsl:for-each). At the end of the process, one file (a java class) is produced that combines the code snippets from your XSP and the logicsheets used. Looking at this file is very interesting and will help you understand. I believe the concepts section describes this very well. Thus variables in logicsheets and XSPs basically have the same scope. BTW this is the reason why it is no good idea to declare variables in logicsheets -- clashes might appear e.g. when a tag that declares a variable is used more than once on a XSP. Extra care must be taken to do this safely. All variables that have not been declared static should be reinitialized for every request. For variables to persist in a specific session, they must be added and retrieved from the session. There's a taglib provided with cocoon2 that does that.

Because of the SAX stream approach that Cocoon 2 uses, the XSP page is being serialized AS it is being parsed.

Once the root element has been propogated, there is no turning back. Ok.. Could you clarify a bit how and in what order things are done in Cocoon. What exactly does Cocoon do with a xsp page (that has been compiled into a java class)? The compiled java class constructs a SAX document, which in turn is XSLT processed if needed. Right? Isn't this the basic flow of things? Only that there's no SAX document. While the XSP still generates SAX events (document nodes), others are transformed and some are already serialized and send to the client. Everything happens concurrently. Thus when 50% (1%, 99%) of the document have already reached the client what semantics should a redirect have? C2 had a send-redirect in the response taglib. And if you were lucky, the redirect was issued while the servlet engine's send buffer was only filling up and nothing has been delivered, yet. Most of the time the redirect never reached the client or two documents were concatenated (i.e. IE) Chris. -- C h r i s t i a n H a u l [EMAIL PROTECTED] fingerprint: 99B0 1D9D 7919 644A 4837 7D73 FEF9 6856 335A 9E08 - Please check that your question has not already been answered in the FAQ before posting. http://xml.apache.org/cocoon/faqs.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Both illustrate different usage patterns so get the CVS version and look at the examples. Action sets are a way to reference a couple of actions together. Which ones get executed is determined by a request parameter named cocoon-action. On my understanding, I'd like to present a step-by-step addition to the Actions documentation. Great!

For now, from this discussion, I understand that we are all looking for some form of automated/simplified form generation/validation and handling..am i right?.. Right. And also, there are efforts on going with current cocoon reg form validation and other stuff...they seem to follow the xform approach from nanotech..but not sure if the original author has intent of extending it to be full blown form generator/validator/handler or not... Well, I'm not the original author but have supplied some of the validations. Indeed, I would like to extend this to a more complete form generator/validator. But I haven't made up my mind, which way to follow. To me, XForms looks like the most importand standard on this but I think it is not advisable to aim for a fully compliant implementation for C2 because (please correct any errors) a) XForms expects XML encoded parameters. I'm not 100% sure on this, but I think few to none of the available browsers support this. I don't think it would make sense to convert request parameters to a XML representation before processing them since this would probably be too costly. A Javascript solution to post parameters as XML is propably out of the question. b) XForms allow besides the basic types arbitrary types definable in XML Schema. While this might be possible for validation, it is expensive but seems only necessary if parameters are XML encoded. c) XForms declare forms within the HEAD/ section of a document. XSP don't have such a concept. d) XForms' forms can be mixed and nested. This is not possible with current XHTML forms. e) XForms specify validation as XPath expressions. Makes only sense if form data is accessible through XPath. f) XForms specify active behaviour: triggers, conditionals ... This is probably out of scope. g) XForms provide sliders, subpages, lists c. This is too complex for short term availability. h) XForms specify subpages. Whiles this could be done it's also probably too complex for short term availability. i) XForms don't specify error messages. j) Since validation is (at least additionally) server based, this should keep the already filled in elements. From this follows, that a fully compliant implementation should not be the goal. To do would be (not necessarily in order of importance) 1) enhance form validator action to validate more XForms basic types. 2) provide a taglib that combines necessary features from formval.xsl and request.xsl plus some form specification that produces valid XForms 3) provide stylesheets that render HTML-4.0 forms (probably separate ones for IE, NS c), XSL-FO c. 4) provide javascript routines that do client side checking (as well for major platforms) Suggestions, ideas and helping hands welcome :-) Chris. -- C h r i s t i a n H a u l [EMAIL PROTECTED] fingerprint: 99B0 1D9D 7919 644A 4837 7D73 FEF9 6856 335A 9E08 - Please check that your question has not already been answered in the FAQ before posting. http://xml.apache.org/cocoon/faqs.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I'm not 100% sure on Which means that for the two standard submission types (url encoded and multipart), the XPath expression is used to reconstruct the XML document. So, do you think this is advisable, to reconstruct the XML? c) XForms declare forms within the HEAD/ section of a document. XSP don't have such a concept. This is a markup issue. Basically, the instance/schema/binding info is stored at the top of the document in an xform tag. As there's no part of an XSP that is an equivalent of the HEAD/ part, the question arises where to put it instead. Just anywhere at the top? Anywhere before the first form element? Or, what the hell, like before with HTML forms, all form elements nested? d) XForms' forms can be mixed and nested. This is not possible with current XHTML forms. This is true. There are two potential solutions: 1) only have one form for the whole document and separate the markup and validation at server side. This is probably the way to go. Although different target URIs for different forms would be cleaner, this could be achieved by action + matchers on parameter values instead of URIs. Such matchers already exist in C2. 2) force the user to use XHTML form constraints. e) XForms specify validation as XPath expressions. Makes only sense if form data is accessible through XPath. In an XForms implementation this is a requirement. Validation is done via Schema (current spec), as well as Dynamic Constraint Language (based in part on ECMAscript). References are by XPath. I think this could be postponed to a later evolution of such a package, can it? f) XForms specify active behaviour: triggers, conditionals ... This is probably out of scope. This can only be in scope if you have a transformer that creates Javascript on the fly. As different browsers have different methods of referencing form parts, this is where the BrowserSelector can come in handy. Again, this is not easy. So, again, this shouldn't be part of an initial offering. h) XForms specify subpages. Whiles this could be done it's also probably too complex for short term availability. I would implement it as another page in the form. In other words, we do validation on the information we have, and go to the subpage, etc. This is a (minor?) breach from C2 philosophy, to split different views into separate XSPs. OK, this is not really relevant here and therefore more or less OK. Again, an issue for later revisions. i) XForms don't specify error messages. This is my biggest beef with it. They have heard this complaint before. Well, we could extent and embrace ;-) A similar functionality could be done with the switch/ contructs in XForms and those triggers. For usability error messages would be quite important to be available in a clean and simple way. And as you said, XForms is a moving target, so perhaps, this is going to happen anyway :-) To do would be (not necessarily in order of importance) 1) enhance form validator action to validate more XForms basic types. XForms is now completely Schema based. Throw the generated XML through Xerces and see what gets kicked out. I would implement the ErrorHandler so that all errors can be cached. Mmmh, another source of errors in C2. Not valid Schema definitions. And a reason to really reconstruct the XML. Think I'll need to look a bit closer at XForms :-| 3) provide stylesheets that render HTML-4.0 forms (probably separate ones for IE, NS c), XSL-FO c. I started on this a while ago. The overall style really depends on the site. Bottom line is that XForms is a moving target. Granted. But there need to be an example so that a form package is usable and as a starting point for every one else to customize. Of course there're a number of design alternatives in the XForms spec. e.g. selectOne/ - radio buttons, check boxes (?!), drop down boxes (select size=1/), select boxes (select/), ... and such a stylesheet would probably provide only one or two of these i.e. based on the number of item/s. 4) provide javascript routines that do client side checking (as well for major platforms) This really would have to be both platform and XForm specific. The Javascript would need to be auto-generated. I think some basic checking could be done independantly, check that a field only contains numbers and display a pop-up if there's a violation should be manageable.

I have a question about Martin Man's session validation example (e.g.,
http://localhost/cocoon/protected/login). Namely, the session validator is
called every time that a match (map:match that is) is done in the sitemap.
I.e., if I surf to protected/protected it first checks with the session
validator action to see if I've logged in. I continue only if my request has
the appropriate session parameter/cookie. At the time, the author, Martin
noted that he didn't like having to put the action in every match entry in
the sitemap that he wanted to protect against unauthorized logins. My
question is whether this can be done. I.e., can I route everything though
say URL match protected/**, do the session check in that map:match, set
some sitemap parameter, and then redirect to another URL (say
rootname/{1}).
The idea is that the session validation appears only once in the sitemap,
but is checked for a variety of URLs. Is there anything wrong with my idea?
Are there simple ways this session validation can be bypassed?
There're several solutions to this:
a) mount a sub-sitemap and do the validation in the mount (probably
not nice, since this belongs to the application in the sub sitemap)
b) nest your pipelines. There's no reason why you shouldn't specify
matchers nested inside an action
c) use redirects to internal URIs or ressources. But then you'd need
matchers for those

But if if change it to use it in the following way: map:match pattern=*.html map:act set=helpdesk map:generate type=serverpages src=helpdesk.xsp/ map:serialize/ /map:act /map:match C2 delivers resource not found. It's not a problem with the LoginAction class. It gets loaded and executed without any problems. I can post the source if needed. Mmmh, does it make sense to nest a subpipeline in a action *set* ? Perhaps you wanted to use a single action? E.g. map:match pattern=*.html map:act type=helpdesk !-- -- map:generate type=serverpages src=helpdesk.xsp/ !-- no transformation needed ? -- map:serialize/ /map:act !-- you should have an else case here, since what happens if the action did not complete successfully ? -- /map:match Chris. -- C h r i s t i a n H a u l [EMAIL PROTECTED] fingerprint: 99B0 1D9D 7919 644A 4837 7D73 FEF9 6856 335A 9E08 - Please check that your question has not already been answered in the FAQ before posting. http://xml.apache.org/cocoon/faqs.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Well :) ... I am finally smiling... The trouble has finally gone away.. and
i'd like to thank you all for
your suggestions adn pointers... especially Scott Boag, cause what he

Initially i had
xsl:stylesheet xmlns:xsl=http://www.w3c.org/1999/XSL/Transform/mmm
version=1.0
and then i had it changed (according to Mr Scott's mail) to:
xsl:stylesheet xmlns:xsl=http://www.w3.org/1999/XSL/Transform;
version=1.0
All was fine after that...
But i read somewhere that the URI can be anything as long as its a
unique string... then how come it has to be so specific... could anyone
correct my concepts here???
You're right. However, cocoon determines the taglib to be used by
prefix + URI. Change anything and it doesn't find the right taglib.
With stylesheets this is not that restrictive, because you specify the
file in the sitemap. Still, you need to have the very same namespace
declaration in your document and your stylesheet. Since xsl is not a
stylesheet but built into the xsl processor and thus is unlikely to
have been changed by you, you need to use exactly the same namespace
URI that has been set by w3c. You might get away using a different
prefix though but I wouldn't bet on that.
I know that taglibs are usually implemented with stylesheets but I
find it very important to differentiate on the role that a stylesheet
takes. Therefore when I refer to stylesheets implementing taglibs I
use the term taglib. These are applied only when the document itself
changes, i.e. to generate java source code from an xsp. They are
registered with cocoon in your cocoon.xconf.
What I refer to as stylesheets are of course stylesheets, but those
that are applied to the document every time output is produced, or
more precise they are applied to the output of the generation
process. These stylesheets are specified in sitemap pipelines.
Whats fumbling me now is the exact sequence an xsl stylesheet is processed.
It used to be reverse declaration order for taglibs. But since it
seems not necessary anymore to declare all namespaces (i.e. those that
are not present in the original document but get introduced by
taglibs), this might have changed.
Stylesheets get applied in the order specified in your sitemap
pipeline.
Anyway, with taglibs they should be written in a way that all taglibs
of one stage should be applicable in any order. When all declared
namespaces of a stage are resolved to taglibs, the next stage begins
with the namespaces added by the taglibs from previous stage.
Cocoon is very verbose. Look at the log and you see every taglib being
applied.
Chris.

This, however, is *after* evaluating the action. Thus

Sure, just have the same parameter names. You might even want to set
your descriptor as default descriptor.
Unfortunately, the fields are numbered like this:
input name=country1 .../
input name=country2 .../
to
input name=countryN .../
If there is no chance of renaming those parameters to country, you
would indeed need to duplicate the entries in your descriptor, there
is no wildcard match operator. Perhaps you could distinguish the
different forms by a hidden value (or the value of the submit
button?), referer URL or target URL? You might still be able to use
the same pipeline in your sitemap.
And one more thing:
I want to have in the sitemap a general entry for all validation actions,
somehting like:
map:match pattern=validate-*
!-- first validate whether submitted values are ok --
map:act type=form-validator
map:parameter name=descriptor
value=context://mysite/mydescriptors/{1}.xml/
This is OK, {1} is replaced by the match from the pattern matcher.
map:parameter name=validate value= /
You could use {1} here as well, perhaps it would be cleaner to switch
to the newer set-based method. See docs, section Forms for this.
map:redirect-to uri=process-{1}.xsp/
This is no good, since AFAIK redirect is done by sending a redirect
message to the browser -- and the request parameters will be
lost. cocoon: protocoll might solve this (cocoon:/process-{1}.xsp,
don't know off head if this keeps parameter) or a redirect to a
ressource does (sure on this).
/map:act
/map:match
Is there a wildcard for the validate parameter values ?
No. But it would be nice to have one, since this way it could be used
to validate input for the database add action when multiple rows are
to be inserted. A patch would be welcome :-)

Thanks for answering,

Sorry cib, I thought it was obvious after I pulled the lines
together. You declare a method main(String[] args) and call main()
without arguments which is a totally different method, hence no
matching method found. Remove the argument from your method
declaration and try again. You seem not to use it anyway.
BTW I always though that main is used only as an entry point for
when no other method could be specified. Often it just invokes the
constructor which does the real work. Therefore you don't really need
main(String[]). Just call class methods or put the logic into a
constructor.
I'm trying to output an xsl and save it to the disk. As nobody knows how to
do that I'm making a patchwork code of java bits I find anywhere: java
classes are far beyond my capabilities: I'm only a postman.
Thanks anyway.
I don't know if this works, but have you tried to use the cocoon:
protocol as source for a transformer? You might be able to obtain the
xsl through that.
map:match pattern=genxsl
map:generate type=serverpages src=generateXSL.xsp/
/map:match
map:match pattern=foo
map:generate ../
map:transform src=cocoon:/genxsl/
/map:match
I haven't worked with this before but I understand that this should be
a valid application for it.
This way you XSL is not saved but I presume that the original
intention was to use it in a transformation with cocoon.

So if you'd put multiple actions in a set, only those with a matchin action tag would be triggered. Here, however, you use a simple action. These are executed regardless of any parameter. The lower part will only be executed if your action fails or after the statements within are completed (wich doesn't occur since these terminate the pipeline).

It depends a bit on how complex the differences for each user are. You
might get away with
map:transform src=resource:/styles/look+feel/{user_credentials}/
in every subpipeline. Or, if there are many subpipelines, you could
create a resource that does the styling (and serializing) and
map:redirect-to resource=look+feel/
or, for more complex stylings even
map:redirect-to resource=look+feel/{user_credentials}/
in every pipeline where it's applicable.
In addition, you could use selectors to chose between different
look+feels based on some user parameter.

Re: LF: passing parameters to resource

You're welcome :-) Approach with map:parameter name=target value=welcome/ generates code in wrong place, which cause compilation error of sitemap. So I guess it could be treated as a BUG. I tend to disagree here. There's no language element that allows setting of sitemap parameters er, variables. They are usually the result of sitemap components execution. More in particular, from those components that are used to determine the actual pipeline from the given fragments (matchers, actions; selectors return only true / false). map:parameter/ is used to do runtime configuration of those components. map:redirect-to/ is no component but a control statement and thus doesn't take runtime configuration. I agree, though, that @target is probably not as clean as possible. A better solution would be, to introduce some construct to set those variables without the need of an action, like map:variables map:parameter name=foo value=xyz/ map:parameter name=bar value=uvw/ /map:variables that is translated by the following in sitemap.xsl (not tested!): xsl:template match=map:variables Map map = new HashMap(xsl:value-of select=count(map:parameter)/); !-- actually, here we could as well use for-each since only map:parameter would be allowed here.

/map:match
But both alternatives do not work after generator- and transformer-calls.
Do I oversee something ? Or do I have to implement an action...
Beware: resource != resource
resource = any URI = map:redirect-to uri=/ = not possible after generate
resource = map:resource/ = map:redirect-to resource=/ = possible everywhere

The result is the XSP server page. (what you refer to in your message as output is I would say is your server page; this now needs to get executed) I'm no familiar with Ant, can you tell me how to do it (some build.xml i gues?). Or how to do it in cocoon, because that is what i was trying to do.

When mounting subsitemaps they are given a directory attribute. For

But I can find no documentation at all, about that point.
Anyone has a link?
Any docs has been updated in addition to the page available at:
http://xml.apache.org/cocoon/userdocs/xsp/esql.html ?
My problem is to have something like:
query1 select foobar, foo, bar from table1;
for each foobar: {
query2 select * from table2 where field1=current-value-of foobar;
for each barfoo (selected by the previous query, inside the '*'): {
query3 select * from table3 where field1=current-value-of barfoo;
}
esql:get-columns ancestor=1/
esql:get-columns/
esql:get-columns ancestor=2/
}
I do not plan to use a single complicated SQL request in order to have a
flat XML
output.
Have a look at the esql docs and look at the grouping example. It
might suit your needs. The ancestor feature is very simple: add the
attribute ancestor with the count of queries to any
esql:get... element.

But you can work around it by using specific prefixes to your vars. Best is to avoid vars in your logicsheet. Use one or two global vars as reference to some complex structures like beans and set their properties. Once properties are set, call your beans methods. What's a little strange is that I get the fine result to generate the select command but it doesn't work for the get-string calls. Try to nest esql:param name=columnxsp:exprcolumn_number/xsp:expr/esql:param elements in your esql:get-string tags. Should suffice. Or, if column is determined statically be logicsheet, you need xsl:attribute name=columnxsl:value-of select=$column/xsl:attribute Mind you, perhaps you need to copy-of instead of value-of.

Derek, we would need to know how your pipelines look like. I assume

Sharat,
your logicsheet seems to expand eclipse-data:get-planet-data/ to more
that
a simple esql:get-XXX/. You should create a tag that does all the
connection
setup and nest the eclips-data:get-planet-data/ inside.
The function eclipse-data:get-planet-data data=sundist name=Mercury/
expands as follows:
connect to the database using esql and return the value as a double.
Yep, this translates to the code above. Don't forget that in the end,
*all* logicsheets are translated to java. Somewhere the connection has
to be obtained. Obviously, you can't do that in the middle of an assignment.
All the function does is return the value from the database without any
surronding tags.
Since I first posted this message I changed the function so that instead of
assigning mercurySun (java double variable) as follows:
mercurySun = eclipse-data:get-planet-data data=sundist name=Mercury/;
I now have:
eclipse-data:get-planet-data data=sundist name=Mercury
variable=mercurySun/
where the function in the logicsheet assigns assigns the value. This works
fine, I'm still not that advanced in using Cocoon and so cannot workout why
I can't assign the value in the calling XSP file rather than the logicsheet.
see above.
If you can it would be aprreciated. It is a bit annoying to do the above but
it has shortend my code by quite a considerable amount compared to entering
a multitude of esql commands and logic.
you could
eclipse-data:connect
xsp:logic
mercurySun = eclipse-data:get-planet-data ./;
.
/xsp:logic
/eclipse-data:connect
with eclipse-date:connect/ translating to
esql:connectesql:execute-queryesql:query...

Maybe anybody knows any howto document or the way what to handle this exceptions. I don't handle errors in sitemap.xmap (if it has any importance). And second question: how to handle db error when I would to use Database*Action? Is any method to handle this error in sitemap.xmaps pipeline ? IMHO error-results refers to errors returned by the database system. Any setup error would not be catched and lead to a cocoon error. As for the SQL syntax error -- errors during execution are not handled in error-results (why?) but only exceptions that occur while retrieving the results. Database*Actions will also cause cocoon errors when connectivity is broken. Other errors can be handled by nesting sitemap elements inside your action for the success branch and those for failure after it. The elements nested will only be considered for your pipeline if the action signalles success. HTH.

Re: esql and db-actions error handling
On 12.Apr.2002 -- 10:12 AM, Jerzy Kut wrote: If I understand Your explanation it is correct construct that should provide handling db errors. So how to handle this? You're right. Sometimes I forget all the differences between the original database actions and those in scratchpad With the ones in scratchpad you could specify if they should throw an exception or continue. The original actions don't offer this. Would be easy to do it, though. Might have a go at it next week. During working of website it is possible to occur damages with DBServer. How to handle this errors? Often it will be connection errors. Or errors resulting from transaction fails or constraints violations. I think connection errors would need to be resolved at sitemap level with a new error handler but I may be completely wrong. The rest should be possible with the above. Maybe good way to resolve it will be write own Database*Actions provides to handle this errors? What do You think? (But of course I welcome simplest method resolving this trouble..) I would strongly suggest to use the database actions from scratchpad. Or modify the original ones and send a patch :-) Chris. -- C h r i s t i a n H a u l [EMAIL PROTECTED] fingerprint: 99B0 1D9D 7919 644A 4837 7D73 FEF9 6856 335A 9E08 - Please check that your question has not already been answered in the FAQ before posting. http://xml.apache.org/cocoon/faqs.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

OK, I've been blind (and you've been stupid ;-)
You try to construct a result set from a string. That is obviously
impossible. So, if you want to use the above syntax *and* your SP does
return a result set object for that parameter, you'd need to
esql:get-object/ inside esql:result/. Please be aware that line
breaks inside esql:result/ could spoil your party. But then you'd
need to have another esql:results/ nested inside your
esql:results/...
If your SP does not return a ResultSet for that parameter, use
esql:call-results/ which are executed regardless of the result
returned by the SP. Use esql:get-string from-call=yes column=1/
to access it.
If your SP returns exactly one ResultSet through e.g. parameter 1, you
could use esql:call resultset-from-object=1{.}/esql:call and
save yourself the trouble of constructing a new query result.
Your example code mixes two of these approaches.
HTH
Chris.

Re: Splitting the request URL

What I would like to do is include a set of navigation links based on the

a href=/website/topicstopics/a /
a href=/website/topics/academicacademic/a
I'm not using XSP, and would like not to if possible. At a guess I'll need
to create an action to parse {1}, and add to the sitemap an entry
containing the HTML for the navigation. This approach just doesn't feel
elegant to me, but then again neither does using a Xalan extension function.
You can pass the parameter to a stylesheet and do it this way. Or
write a transformer that includes your navigation. Perhaps cinclude or
aggregation come in handy, too, depending on the complexity of the
task.

I see my form parameters are succesfully valitated, but cocoon pass to the map:generate part directly. I fear that nesting does not work with action-sets. Check by looking in the logs for the invocation of the db action. If there's none, look at the code generated for your sitemap. I bet that you won't find any reference to your db action in there.

Such a get/set interface is about all that makes beans special (mind you, this is about plain java beans, no J2EE stuff). On the whole a solution is often to employ proper nesting.
