RE: Connecting database and XML pages

[Terry Paddy]

Same thing happens with PostgreSQL :( but there are
lots of messages about this problem and you can see
some info in the Turbine project. The important thing
is ... its not your setup, it appears to be a bug.

RE: Debugging Custom Generators & Transformers

[forge]

I've had this same problem before.

It has to do with the wrong jar files in the wrong directories. I believe
it's in the FAQ.
rename xerces/xalan to 1xerces/1xalan,
remove jaxp.jar and one more jar, but I can't remember which one :)

RE: Connecting database and XML pages

[annemarie . hartvigsen]

OK,

I tried to implement your example, but can't get the connection pooling to
work (I guess). It _works_ when I _don't_ use pooling, so I can't understand
what's wrong. The driver is mm.mysql 2.0.4 and is located in
TOMCAT_HOME/lib.

Below is the error message and cocoon.properties:

RE: Debugging Custom Generators & Transformers

[Kaufman, Noah]

Folks:

Actually, I guess I spoke too quickly before.  Although we have
gotten the latest build of Tomcat to run under Visual Age for Java, we
are not able to make Beta 2 of Cocoon 2 work in this configuration.

The cocoon.log file has a lot of information in it, but the
error can be summed up by saying that for some reason Cocoon is unable
to locate the proper component handler to read its own sitemap.

Has anyone had any experience with running Cocoon 2 under Tomcat
inside of VAJ, and if so - what do we need to do to make this work
properly.

I have enclosed the output from the relevant section of the log
(the tail end) after my signature.

Sincerely,

[annemarie . hartvigsen]

Hi,
 
I'm 
trying to run a query and it will not work properly. in mysql I have two tables 
and I run the following query:
 
mysql> select deviceID, 
description from terminal, deviceType where deviceType.deviceType = 
terminal.deviceType;+--+-+| deviceID | description 
|+--+-+| 57685251 |

ISDN    || 90098999 | 
GSM || 95755499 | 
GSM 
|+--+-+5 rows in set (0.00 sec)
 
When I try to run it on a xsp page (see code at the bottom of the page) I 
get the following result:
 


  
  
Device ID

As far as I can see 
the where condition is not working when I run it in the xsp page (as you can see 
below this is the result when the query is run without the 
condition).

What's the problem? Is 
there something special about the esql syntax? Or is it something 
else?
 
Anybody who can figure it 
out?

spent a day or something searching for the 42th workaround but the thuth is
in the code:

shame on me i read the code four or five times without seeing what jumping

Debugging Custom Generators & Transformers

[Kaufman, Noah]

Folks:

For an application that we're developing under Cocoon 2 using
IBM's Visual Age for Java v3.5.3, we are developing a couple of custom
generators and transformers.  Although we can use println to write out
debugging information, what we would really like to do is to be able to
use the integrated debugger inside of the VAJ IDE to be able to debug
our code.

Following instructions on the IBM VADD site, we've gone ahead
and gotten Tomcat and Cocoon to operate successfully within VAJ -- and
we're able to debug other servlets and JSPs in Tomcat by following the
steps outline on the VADD site.

What we can't (yet) do is set a breakpoint in a Cocoon 2
component, for example the HTMLGenerator, and then run the HTMLGenerate
example that scrapes data off of the Yahoo site and get the debugger to
break on a previously set breakpoint.

What "magic" step are we missing here that would allow us to do
this?

If you're using JDBC calls, you should have a look at the dedicated
section of the excellent Java tutorial at
http://java.sun.com/docs/books/tutorial/jdbc/basics/prepared.html
It is explained here certainly better than I could do !

If you're using the esql logicsheet, I cannot be of great help since I
don't use it, but Christian told that  generates
prepared statements.

I've written such an action, wich captures the output of an XSP or parts
of it an stores it in request attributes as XMLFragment instances.

However, there is some discussion going on on cocoon-dev on the way it
is written. So stay tuned, it will certainly be available soon in the
Coocoon 2.1 branch.

Re: [c1] xsp:logic compiling

[Christopher Painter-Wakefield]

Brent,

it sounds like you are getting there, maybe a few hints will close the gap
for you.

First off, you *can* apply multiple logicsheets to an XML document.  Use
the  processing instruction multiple times for
logicsheets that aren't associated with a namespace in the
cocoon.properties file, and declare the appropriate namespaces for all
logicsheets.  You may also use one logicsheet inside another logicsheet, as
long as you declare the namespace for the secondary logicsheet both in the
using logicsheet and in the XML file (and add the appropriate
 PI to the XML document if necessary).

The rest of your issues can be dealt with by looking at the sequence of
events when processing your XML.  First, the Cocoon processors get applied
in the order in which they are requested via 
PI's.  If you are using XSP, then that processor should *always* be first.
(In Cocoon 1, you can get away with putting an XSP processing step later,
but it can work kind of funny and it is also slow, since you get a
compilation every time the page is requested.)

When the XSP processor is applied, things happen in roughly this sequence:
1.  All logicsheets are applied to the source document using normal XSLT.
So for instance, if you use two custom logicsheets using the
 PI and also use the request logicsheet (and all
three namespaces are declared correctly), then each logicsheet will be
applied to the XML source as an XSL Transform in turn (the output of one
becomes the input of the next and so on).  I'm not sure of the exact order
in which the logicsheets will be applied, but common sense would suggest
that the order of  PI's and the order of namespace
declarations will be significant.
2.  After all logicsheets are applied, the XML is transformed into Java
code (this is also done mostly using XSLT, I believe - look for the
xsp-java.xsl file in your Cocoon src tree).
3.  The Java code is compiled.
4.  The resulting code is loaded and run to generate the XML page.

The resulting XML from this step is passed on to any other processors down
the line, including your XSLT processor.

This should explain a few things for you.  First, you can't really use the
request taglib from inside a stylesheet.  Even if the logicsheet were
applied, you'd just end up with uncompiled Java code, which won't do you
any good.  All logicsheets have to be used in the XSP step.  You can,
however, use the request logicsheet in your XSP program, storing the
results in a tag that you can later process in your stylesheet.

Second, you can't mix Java logic and XSLT logic, which is what you do when
you try to use  syntax on the result of the
.  Keep in mind that the XSLT is just what is
applied to the XML to help transform it into Java code.  The
 tag gets transformed in that way.  If you look at
the actual request.xsl logicsheet (in your src tree), you'll see that the
 tag gets transformed into something like
   XSPRequestLibrary.getParameter(
   request,
   String.valueOf("whatever"),
   "",
   document
 );

So, the request code gets run and gives you a result much later in the
process than when your  is applied.  Your  is not
turned into Java code itself, it is applied as XSLT to generate the Java
code.  This is why you can get the results of the request tag in your
output but not use the  in your logicsheet on the result.  One
is dynamic, giving a result at runtime.  The other is static, generating
code that will be compiled once and run many times.

Oh yeah, that's the other thing.  If you don't change your logicsheets or
source XML, then the next time a request is made to that XML, none of the
logicsheet application and compilation is done - the existing program is
merely re-run.

Anyway, to do what you want, you need to mix apples and apples as it were.
You can either mix Java with Java:

  if ("whatever".equals()) {

  This screen is 'whatever'!

  } else {

  Wrong screen!

  }


or mix XML with XSLT:
(in your XSP program or logicsheet)


(in your stylesheet, later in the chain)

  

    and so forth.

Finally, if all that wasn't enough, note that you can gain access to
request parameters in your stylesheet (not your logicsheet!).  Coocon does
some sort of trick to make these available.  Merely declare XSL parameters
with the same name as your request parameter at the top level of your
stylesheet, like so:

See the user guide (http://swift.mc.duke.edu/cocoon_docs/guide.html) for
more on this approach.

I hope some of this is helpful.  Good luck!

-Christopher

No, actions have a different role to fill. However, this is possible
with a transformer. See logtransformer & ReadDOMTransformer.

How to getConnection in Action ?

Hi All,

   I try to use Action in the Sitemap to dinamicaly select stylesheet file  base on 
the request 
*.xml file. so in the Action, i need to get a connection from the connection pool to 
connect to 
the database. But How to get the connection ? I have read the Cocoon2 Documentation ( 
section

org.apache.avalon.ComponentManager, org.apache.avalon.ComponentSelector ) from the

   Do you have any idea ? 


Thank you.

Get Connection in Action

[Ling Kok Choon]

Hi All,

   I face a problem to get database connection in Action, i followed all the step in 
the cocoon2 
documentation ( section Using Databases ), the example is not very complete( included 
below ). 
Do you know how to solve this problem, please tell me 


** Example From Cocoon2 
*

import org.apache.avalon.ComponentManager;
import org.apache.avalon.ComponentSelector;
import org.apache.cocoon.Roles;
import org.apache.cocoon.component.datasource.DataSourceComponent;

import java.sql.Connection;

//  Skip a lot of lines until we are in the method you use
//  to initialize the DataSourceComponent 

private DataSourceComponent datasource;

public void compose(ComponentManager manager) {
ComponentSelector selector = (ComponentSelector) 
manager.lookup(Roles.DB_CONNECTION);
this.datasource = (DataSourceComponent) selector.select("MyConnectionName");
}

//  Skip more lines until we actually need to use the datasource

private void meMethod() {
Connection myConnection = this.datasource.getConnection();

//  perform SQL code here

myConnection.close();
}

** End Example From Cocoon2 



Thank you.

Serving files out of a database

Hi,

i've got the following problem:

I'm using a postgresql database. The user of my web application (C2)
cann upload files (of any kind ) into the database. Now i want to serve them
to user on request. Now i wondering how to integrate it into C2. I was
thinking about to write a specific Generator, which query the db and
pulls out the file data, but it seems for me that Generators are only used
to produce XML conform data, which will be further processed in the
pipeline.

Does anyone have a solution or any idea how to do this??

===> See also attached Cocoon.log <===

Background Infos:
C2 on WNT SP 6 with Tomcat 3.3
Oracle 8.1.5 EE on NT
Web Server is IIS 4.x
Connectivity to Oracle works

Question is: what's wrong ?

Could anyone help me ? I need the Validation stuff to work 

Another info: I got this error also with previous CVS of C2. I noticed
the source has been changed exactly at that point
(SessionValidatorAction.java:136). But still the effect (error) remains.
Maybe I am doing something wrong ?

Thanks in advance!
Cheers
Matteo Villa
