Re: Changing request Parameters in an Action.

The answer I found was using Javascript to change the values of 2 hidden 
parameters using the OnChange event of the object select.

Changing request Parameters in an Action.

2002-10-06 Thread Antonio Gallardo Rivera 

Sorry but, I am reopening this, because I need to change some parameters on 
the client form before I can add it to the database.

I have a 2 fields database key:

cat_id (foreign key from table categories)
pro_id 

In the table are some values:

cat_id  pro_id  pro_name
1   1   product1
1   2   product2
2   1   product3
2   2   product4

I need to let the user select the product from a HTML page in a combo basis. 
Then i can code:


product1
product2
product3
product4


When the user send the request I get a parameter my_product="x-y". Where x is 
the encoded value of cat_id and y is the value of pro_id.

Now my problem comes to life: How to create new request parameters into an 
action to make 2 new parameters:

cat_id="x" and pro_id="y"

Please help me ;)

Thanks, but a quick browse through the source doesn't reveal anything 
about forced caching.  To be more specific, the HttpClient would support 
caching of content that is flagged as cacheable by the server, but if 
they server doesn't send an expires header, HttpClient (to my knowledge) 
would make just as many requests but with an If-Modified-Since header. 
 Since the feed on the server is a static file that periodically 
generated, HttpClient may save bandwidth, but do basically nothing for 
server load.  Somehow I think the latter is of more interest to the 
Slashdot folks since the file is about 6K.

What I'm looking for is a way to mandate to my Cocoon installation that 
I don't care more often than every thirty minutes.  As a bonus, I'd like 
it to allow the cache to agree so that my stylesheets aren't reprocessed 
unnecessarily.

I know.  I'm asking a lot.  ;-)

Wasn't Gianugo Rabellino working on something like this?

Try the WebServicesProxyGenerator.
It uses the HttpClient library, which might actually support caching. Have
not tried it though.

Re: Changing parameters of request inside Action

2002-10-06 Thread Antonio Gallardo Rivera 

Thanks. I will try in another way:

1-generate a random key - I will generate at the request time from the XSP.
2-Create a timestamp - Like above.
3-Validate a code numer based on the category of the selected product - 
Validate in an action.

Thanks.

RE: Changing parameters of request inside Action

2002-10-06 Thread Ryan Agler 

I am not sure how to alter request parameters, but I do know you can
set/change request attributes.  So, If you had an action with a
statement like request.setAttribute("myAtt","10"), and then you could
call request.getAttribute("myAtt") from subsequent actions or xsp.

Is posible to change parameters request inside an Action?

I need to set some parameters before insert into the database.

For example:
1-generate a random key
2-Create a timestamp
3-Validate a code numer based on the category of the selected product
after 
the user select a product and write a number.

URL caching in pipelines

2002-10-06 Thread Miles Elam 

I want to put a Slashdot feed on my web page with the following (out of 
context for brevity):


  
http://slashdot.org/slashdot.xml"/>

  


This works fine, but the server opens a socket to Slashdot on every 
request to my page.  If my site gets some traffic, Slashdot will not be 
happy with me.  Further, my bandwidth usage goes up.  And when Slashdot 
(and others) become slow, my site will become slow right along with 
them.  None is particularly appealing.

 From the Slashdot syndication page (slashcode): "Do whatever you want, 
but *don't* access the file more than once every 30 minutes."

I went hunting in the mail archives for user and dev and came up with 
the following:


  
http://slashdot.org/slashdot.xml"/>

  


No difference.  My server's still hitting Slashdot over and over.  I 
tried telnet-ing to the port to at least check for "expires" headers. 
 No dice.  I looked at HttpHeaderAction but that doesn't seem to touch 
Cocoon's cache at all (so of limited use to me).  I've used both 2.0.3 
and 2.1 CVS (as of two weeks ago).

A part of me smiles when I think that if Slashdot ever "slashdotted" me, 
they would be somewhat slashdotted themselves, but this is not my intent 
and I very much want to be a decent feed client.

Anyone have any ideas?  ...preferably with little stress on my server.

JBoss-3.0.3_Tomcat-4.1.12 with cocoon 2.1

2002-10-06 Thread Thorsten Mauch 

Hi All
 I try to setup my cocoon Application to work inside the Jboss-tomcat.
I changed from crimson/jaxp to xerces. I also copy some of the jars 
form cocoon/WEB-INF/lib to /server/default/deploy to avoid classnotfound
exceptions.
Currently i can run the cocoon and i see the documentaion. But i got a lot
errors about logging
like:

Random generator

2002-10-06 Thread Antonio Gallardo Rivera 

Hi Folks!

Is in Cocoon support for generating random database keys? Or a function that 
can return a random number?

I know that in Java is support for the Random class. This class generate a 
sequence based on a seed (like always).

The point is: I need generator of random numbers that will live all the 
run-time to return for every request a new random number lets said: 2^32.

Maybe this generator of random numbers can be called inside an action or in a 
xsp fashion.

Thanks in advance

Antonio Gallardo.

*Bizarre* Sitemap Problem

2002-10-06 Thread Sonny Sukumar 

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  section is ONLY the 
following (after backing up the original sitemap.xmap, of course):


  

  
  
  

  
 

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  tag in 
$COCOON_HOME/WEB-INF/cocoon.xconf:



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:



  Hello World
 

And of the helloworld2html.xsl file:


http://www.w3.org/1999/XSL/Transform";>
  

  

  

  


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.

All the best,

Sonny

Problem with modular database actions from CVS

2002-10-06 Thread Hugo Burm 

Hello,

I am using the modular database actions and doing a simple select action on
a table.
With the CVS version of about a week ago, this worked ok, and the results
were stored in the request attributes by the default output module.
With the CVS from Oct 5, I get a warn message : "Could not select output
mode attribute:null" and the values that are fetched from the database are
not stored in the request atttributes. From the log files I can see that the
key is set correctly and the results are fetched correctly from the
database. Storing them in the request attributes seems to be the problem. Is
this broken or do I now have to specify an output module myself?

Thanks
