I have a vague grasp of various ways I could do this if my data were to reside in an intermediate DBMS of some sort, but the objective here is to store each time series as an XML source file only, while still being able to query it.

This is especially noticeable as one of my queries take a minute long.

Giving up! Cocoon too big, slow and confusing
I'm back from a short vacation in beautiful Chicago (it really is much nicer than Toronto or Montreal) and have waded back in to Cocoon for a couple of days. After just a few hours of poking around I have decided that it will be much simpler for me to simply hand-code a whole hat-full of servlets than to try and pull any meaning out of Cocoon and it's documentation. Fifteen hours on the Interstate wasn't as challenging as trying to figure out how one should check a Web Form this month but I didn't have that feeling of travelling backwards half of the time. I was also able to predict and achieve forward progress (for a change). Thanks guys, but no thanks. Maybe I'm getting old, but I really don't understand the need for all of the complexity and the lack of documentation in this product. On the other hand, I used to feel the same way about the mind-numbing complexity of a certain thirty-year-old mainframe operating system (MVS) produced by IBM back in the sixties and it's patching system (SMP4). So it can't just be my age. Anyway, Cocoon has cost me far morte (a typo that's better than the original word) time than it was worth. The chief problems appear to have been endlessly re-invented terminology for an overwhelming number of 'new concepts' and a complete lack of consistency between different components (i.e. functional code, non-functional examples, unbuildable documentation and a website that doesn't match up with any single released version of the project). I have a lot of respect for the ability of the people who have built this project, but I want them to know that their project appears to be out-of-control and could become very difficult to manage. If experienced developers (like myself) can't figure out how to use enough features in the product to make it worth using, then penetration will be limited and all of your efforts will be wasted. There is more to this business than stuffing in features at the expense of documentation and testing. You have a lot of very good ideas, but the execution of the project as a whole seems to be suffering. I know that I will often look at my JSP and servlet code and think 'XSP and Cocoon were sooo much better!' until I remember that I wasn't ever able to use enough of Cocoon to make a profit.

Database Action assistance request.
I have been poking around trying to find out whether
DatabaseSelectAction can help me.
There is very little written about this action and I wonder whether it
has ever been used (or even tested).
My problem is as follows:
I have a column in a table in a database that I am able to access from
XSP and Java with no problems. In the interest of elegance I would like
to make the item available to an XSLT Transformation as a parameter.
All I want to do is supply the key column 'name', get the corresponding
row and then use the value of the field 'company' later in my pipeline
as: {company}.
Sitemap.xmap contains:
map:actions
map:action name=select-user logger=databaseselectaction
src=org.apache.cocoon.acting.DatabaseSelectAction/
/map:actions
And the matching pipeline entry is:
map:match pattern=process
!-- first validate whether user has logged in --
map:act type=session-validator
map:parameter name=descriptor
value=context://alpha/descriptors/params.xml/
map:parameter name=validate value=username/
!-- generate protected content --
map:act type=form-validator
map:parameter name=descriptor
value=context://alpha/descriptors/getfiles_form.xml/
map:parameter name=validate value=filename/
!-- form-validation success --
map:act type=select-user
map:parameter name=descriptor
value=context://alpha/descriptors/getuser.xml/
map:generate type=serverpages src=docs/process.xsp/
map:transform src=stylesheets/dynamic-page2html.xsl
/map:transform

!-- form-validation failure --
map:redirect-to uri=pickdoc/
/map:act
!-- session-validation failed == redirect to login-page --
map:redirect-to session=true uri=login/
/map:match
The value username is captured by a form earlier in the session and
exists as a session attribute.

!--parameter name=company type=string/--
connectionphoenix/connection
table name=users
keys
key param=username dbcol=name type=string mode=form/
/keys
values
value param=company dbcol=company type=string/
/values
/table
/root
I include the username in the URL as I don't know how else to supply it
to the Action.
I have read the databaseSelectAction code and understand how the SELECT
statement is generated.
I have recompiled cocoon.jar with additional getLogger().debug(
yadayadayada. ) statements but these never generate output. Anyone
care to tell me why ?
I have had some success with cocoon but I am finding it difficult to
get through to some advanced features because of the sparse
documentation.

Re: AW: Question: what is {session-id} ? in a sitemap.xmap ?
Thanks. Some of this is starting to become clearer. Unfortunately, it seems that the only way to learn Cocoon is to read the source code. That isn't going to cut it for much longer. It would be nice if there were a list of all of the similar variable types and their purposes and how to set them and use them. Perl becomes understandable (well ... a bit) when the different types of name are explained. unfortunately, it is not enough to set 'fred' as a session attribute, who would have to set it as a sitemap parameter just as Artur said. You can do this inside an action (actions return a java.util.Map and you can use the keys stored in it as sitemap parameters. I don't know if it is there in 2.0.1 but in 2.0.2 you can look in the docs under User Guide / Concepts / Actions and there at 'Communication between Sitemap and Action'. As Artur also pointed out you can call a resource with some parameters which you can then use as sitemap parameters inside the map:resource tag. - 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]
Question: what is {session-id} ? in a sitemap.xmap ?
I have been using Cocoon 2.0.1 for a few months now and have run into a
few brick walls. The most serious limitation is the lack of
documentation for just about everything. I have worked through a number
of problems in the past but am currently frustrated by a number of
questions.
I have often seen expressions in the sitemap like {session-id} and
{target}. it is clear that these are variables substituted from
somewhere magical but I cannot for the life of me imagine what.
Can anyone explain where I can find the documentation for these
constructs ? I suspect that I can use these items to transfer
information in to parameter lists but need to understand this aspect of
Cocoon before I can do it.
Thanks.

Re: Question: what is {session-id} ? in a sitemap.xmap ?
On Thursday 23 May 2002 18:23, you wrote:
Thanks. It is pretty clear that {name} is a variable. My question
should have been: How do I discover the valid values for {name} ?
The example I was looking at used {session-id} which is intuitively
linked to the session-id I would get from session:get-attribute
name=session-id/. Is my inference correct? Does it therefore follow
that I can use any attribute from the session context ? If I set a
session attribute named 'fred' with the value 'flintstone' does {fred}
evaluate to 'flintstone' in a sitemap ?
Is the definition of {name} documented anywhere ? Is there any way of
enumerating defined names ?
From what I know, basically {name} is a representation of
a sitemap parameter which are used by sitemap components.
For example, if your pipeline wants to call another (resource)
pipeline you with a target parameter you would do it this way
map:call resource=simple-page
map:parameter name=target value=some/path/to/something/
/map:call
now in your simple-page pipline you can access that target
paramter with {target} so you can have:
map:resource name=simple-page
map:generate type=file src={target}.xml/
map:transform src=stylesheets/page/simple-page2html.xsl
map:parameter name=view-source value={target}.xml/
/map:transform
map:serialize/
/map:resource
Also, if you implement actions the return of the act() method
is a map that will be added to the session paramters.
In your action of you do
sitemapParam.put(session-id, getSessionID()); then
in your pipeline you can do
map:match pattern=something
map:act type=my-action
map:generate src=something/{session-id}/
...
/map:act
/map:match

Solved a problem: Redirect extension to Xalan
This note is mostly for the benefit of anyone else searching for help with Redirect. Sorry if Xalan is a bit off topic for Cocoon2, but I expect that a lot of XSLT users will be using Cocoon as a framework for Xalan-J/XSLT-based applications. I spotted Redirect in Chapter 8(?) of XSLT by Doug Tidwell, August 2001, O'Reilly and Associates. It does work in Cocoon2 but I had a few problems getting it to run. I finally solved it by looking at the Xalan-J docs at xml.apache.org as well as the source code for Redirect. The Redirect class seems to have moved from org.apache.xalan.xslt.extensions.Redirect to the more concise org.apache.xalan.lib.Redirect. The comments in Redirect are actually useful! (thank you Mr Boag!) It appears that you need to include several namespaces in the stylesheet tag. This was another source of 'the fog of war' for me. xsl:stylesheet version=1.0 xmlns:lxslt=http://xml.apache.org/xslt; xmlns:redirect=org.apache.xalan.lib.Redirect extension-element-prefixes=redirect ... rest omitted ... This did not work for me when I followed examples from various sources. I have one minor complaint about Redirect (may apply to all extensions). This facility is terrific but it is strangely silent when things go wrong. For example, I used file=concat(... at one point and created a directory named concat( When I had mis-spelled namespace URI's nothing worked and it did so silently. When the lxslt declaration was missing ... same thing. I know I had perms wrong and was rewarded again with silence. Thanks again. Hope this helps. - 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]
Re: what is the easiest way to delopy cocoon application?

If yes, how can I create one for my cocoon application (including database)? Take a look at http://sourceforge.net/projects/Chello it is supposed to be a minimalist C2 application. You probably want to clone it as a basis for your application (assuming Apache-ish license). - 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]
Re: sent request to servlet from VB
On Friday 08 March 2002 14:49, you wrote: Hi all, Does anyone know how to call a servlet from VB code? I want to sent the request from IIS to Tomcat without using isapi_redirect.dll. Is possible to do this? I look forward to your suggestions. You need to be able to open a socket connection to the appropriate port on the appropriate server. Then you send an HTTP message that looks like: GET /servletNameFromTheURL HTTP/1.0 followed by several lines of the appropriate HTTP headers. The server will respond by sending a response containing headers followed by some data. The server will finish up by closing the connection. You can do this from VB code. The only question is what level of technical sophistication you bring to the keyboard. You might check out some Visual Basic resources on the net. There is almost no difference between communicating with a servlet and communicating with most other forms of web resource (speed of the response might be better than an equivalent CGI). You need to understand how to send an HTTP request and how to receive and process the server's HTTP response. - 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]
