Re: ServerPageAction: XMLFragment reuse in XSL transformer
Sorry for the delay! Thanks for your answer, Peter. I must admit that I did not compare the performance between the aggregation and the transformer approach. The aggregation is just one additional component in the pipeline, that has to process the big document. Apart from that the necessarykind of processing of the big document requires the XSL-transformer to build an entire DOMDocument before doing the transformations, I guess. So what I have done is I have written a Transformer for handling expandable data like the directory tree in the Windows' Explorer. It requires all input elements to have a unique id attribute. According to the tree status stored in the session, the transformer will only forward the visible tags and drop everything else. It also supports URL commands for setting upthe status tree (only root element is visible or all parent elements of one particular one are visible),expanding and collapsing child elements. Later transformers can then easily do thepresentation of the visible part of the tree and setup URL links e.g. for expanding leaf nodes futhermore. In most cases all SAX processing is done on-the-fly without intermediate storage of all SAX element. The quality of the code is probably not very high, as I am not working with Cocoon for very long, but at least its documented. Do you think this transformer could be useful for other people? And do you know to whom I should give it?

MyFilterTransformer will use the XMLFragment from the session to forward only a small portion of the events from the generator, following your idea. MyFilterTransformer is the first component in the pipeline, which is NOT cacheable, as it returns different data on every request. To my understanding cocoon's caching strategy should cache the pipeline as far as possible. In this particular case only including the FileGenerator: "The keys of all cacheable components are chained, and together they build the cache key. The request is processed, and the document is built. The cache stores the result of the _last_ component, indicating cacheablility. The next time this document is requested, the key is built, and the cached content is fetched from the cache. Next, the cache asks all components of the event pipeline, if their input has changed since the time the content was cached. For example, the generator checks this by looking at the last modification date of the xml document, the xslt transformer checksthe date of the stylesheet, and so on. Only if all state that the content is still valid it is used from the cache. Otherwise, the document is generated from scratch. So the event pipeline tries to cache as much of the XML processing pipeline as possible." from New Riders, Cocoon: Building XML Applications by Matthew Langham and Carsten Ziegeler, p. 182. - Original Message - From: Hunsberger, Peter To: '[EMAIL PROTECTED]' Sent: Friday, October 18, 2002 4:23 PM Subject: RE: ServerPageAction: XMLFragment reuse in XSL transformer Well, obviously, it something changes on every request then, by definition, it isn't cacheable. However, I believe, with aggregation, only the components that are marked as invalidated in the cache are rebuilt on a new request; the rest of the data stays in it's respective cache. This does mean that the aggregated document is rebuilt each time (I have no idea what the impact of that would be). But the "large" document source would stay not be retrieved from scratch. Perhaps using the document function as Olivier would avoid this. At one point document did notcheck cache validity at all and you would only get a newer version of the data if the main data was invalidated in cache. I think this has been fixed in 2.0.3. The problem is how to get the URI resolve for the document function to fund the data in session. Someone else will have to tell you how to do that (and if it's even

There are two cases that can cause XSP taglib markup to be ignored by
the XSP engine and produced as is in the output document : either the
taglib namespace is wrong (this isn't the case here), or the the taglib
isn't declared in cocoon.xconf.
You should check that the following exists in your cocoon.xconf :
markup-languages
xsp-language name=xsp logger=core.markup.xsp
...
target-language name=java
builtin-logicsheet
parameter name=prefix value=xsp-session/
parameter name=uri value=http://apache.org/xsp/session/2.0/
parameter name=href
value=resource://org/apache/cocoon/components/language/markup/xsp/java/session.xsl/
/builtin-logicsheet
Hope this helps.

Using Cocoon from the command
For the first time in a year and a half I want to use Cocoon from the command line. I will be able to use the results in an environment without Cocoon or Java and I won't have to generate every time the data etc etc. I use Sun's JDK 1.4.1_01, Cocoon 2.0.3, on Linux. I've found at least of informations on dejanews and the mail list archives: http://groups.google.com/groups?q=cocoon+command+linehl=enlr=ie=UTF-8oe=UTF-8safe=offselm=jPAd8.9020%240C1.767012%40newsread1.prod.itd.earthlink.netrnum=4 Uh, I should have looked at the code!

I've never compiled Cocoon by sources because in the early days of the 2.0beta it was a pain in *** ***, and I used to download the binary .war.

You should set the correct class path ;-)
Look at the stack trace : one of the first classes loaded from Avalon by
Cocoon can't be found. That's because your classpath is set to . and
so includes only Cocoon's own classes (guessing you start this from the
build/classes directory).
Hope this helps,

AW: Umlauts in cocoon 2.0.2
Hi Braun,
I wrote an action to encode the request params before accessing them in the sitemap:
public class RequestEncodedParamAction extends ComposerAction implements ThreadSafe {
public final static String MAP_URI = requestURI;
public final static String MAP_QUERY = requestQuery;
public final static String MAP_CONTEXTPATH = context;
public final static String PARAM_PARAMETERS = parameters;
public final static String PARAM_DEFAULT_PREFIX = default.;
public Map act( Redirector redirector, SourceResolver resolver, Map objectModel,
String source, Parameters param )
throws Exception
{
Request request = (Request) objectModel.get(Constants.REQUEST_OBJECT);
if (request == null) {
getLogger().error(RequestInfoAction: no request object!);
return(null);
}
Map map = new HashMap();
map.put(MAP_URI, request.getRequestURI());
String query = request.getQueryString();
if (query != null query.length() 0){
map.put(MAP_QUERY, ? + query);
}
else{
map.put(MAP_QUERY, );
}
map.put(MAP_CONTEXTPATH, request.getContextPath());
if (true.equalsIgnoreCase(param.getParameter(PARAM_PARAMETERS, null))){
Enumeration e = request.getParameterNames();
while(e.hasMoreElements()){
String name = (String) e.nextElement();
String value = request.getParameter(name);
getLogger().debug(Encode Parameter: + name + with value:
+ value);
if (value != null !map.containsKey(name)){
map.put(name, URLEncoder.encode( value ));
}
}
String[] paramNames = param.getNames();
for (int i=0; i paramNames.length; i++) {
if (paramNames[i].startsWith(PARAM_DEFAULT_PREFIX)
(request.getParameter(paramNames[i].substring(PARAM_DEFAULT_PREFIX.length())) ==
null)) {

Betreff: Umlauts in cocoon 2.0.2
I have the problem with german Umlauts in request parameters.
When I transfer german Umlauts by request paramaters cocoon doesn't
decode the Umlauts encoding when I use these Umlauts in my xml-documents
or stylesheets.
I set already all my encodings to ISO-8859-1.
