In version 2 of our application we do not return our exceptions wrapped in XML (it is a requirement not to) therefore when we throw an exception now, cocoon shows the horrible stack trace. So may question is: is there a way to intercept the exception before cocoon can report it? Can cocoon generators intercept exceptions so we could write our own generator? Maybe there is a simple answer to this already (apologies if so)?

Handling non XML structures in pipelines?
Hi all, Our scenario is simple, we have a service that returns some strings in a comma delimited format and wed like to use that data in cocoon for various transformations, however is it possible to do something at the generator stage to convert this string into XML or does the source of the generator (e.g. file, stream) have to be in an XML format in the first place i.e. editing our service application to return XML is the only option? I guess what were asking is whether cocoon can handle non XML formatted data? We do not want our service to depend on the client as to what structure we return, such as XML. Many thanks in advance, Ant

Substitute whitespace in request parameters in sitemap?
Hi, Is there any way to substitute whitespace with '%20' in a URL within the sitemap? I am passing in basic Xqueries containing spaces as a request parameter to my sitemap (from an HTML page, not from XSL so I cannot use the strip whitespace attribute); however, as the xqueries contain spaces the URL becomes malformed when the sitemap attempts to call the URL?

Yes. I successfully use Yourkit with Cocoon. See
:doYourkitProfile in
http://svn.apache.org/repos/asf/cocoon/trunk/cocoon.bat to
find out how to start Jetty. Of course this requires a
properly installed Yourkit (IIRC it requires some native
library in the system path).
With this setting you can the JVM access remotly at port 1.
Hope this helps.

Cocoon hangs?
Hi, I have a simple webapp that uses a cocoon transformer to interact with a DB XML database. I find that the browser hangs intermittently when running the webapp, then I find this message in the sitemap.log: [sitemap] (Unknown-URI) Unknown-thread/ExcaliburComponentManager: disposing of handler for unreleased component. role [org.apache.cocoon.serialization.SerializerSelector] Has anyone come across this before?

Memory monitor?
Can anyone recommend a decent memory monitor for Cocoon? I've implemented a Java class transformer which runs queries against a native XML database (DB XML). We've noticed a lot of memory gets eaten and not freed when running the transformer to execute queries. I've waded through the code and made sure all the usual re-initialisation and freeing up of objects is enforced, and we know it's not at the database end as we've run queries using the database shell command line app...it's definitely an issue in the Cocoon transformer we believe. Any recommendations please? Thanks in advance, Ant - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: XSLT transformation
Thanks to everyone's help I believe I'm getting closer to getting this
working...darn...I didn't realize transforming XML in Cocoon could cause
such a problem! I've now changed my code to:
private void generateDocumentToSAX(String queryResults)
{
try
{
XMLReader parser = XMLReaderFactory.createXMLReader();
parser.setContentHandler(this);
InputSource inputSource = new InputSource(new
StringReader(queryResults));
parser.parse(inputSource);
}
catch(Exception e)
{
m_resultMessage = Unable to get parser: + e.toString();
this.getLogger().error(m_resultMessage);
}
}
And I get this error in the sitemap.log:
Unable to get parser: java.lang.UnsupportedOperationException: The
TransformerHandler is not serially reusable. The startDocument() method
must be called once only.
-
I think this might be happening because I pass in XML to the java class
transformer (containing the above method) which finds/creates the
startDocument element in the startElement method, and then the parser in
the method above creates another startDocument element, which is
confusing the saxon xslt transformer? I'm confused here now - if the
purpose of a Cocoon transformer is to take in some XML, change it, then
spit out the changed XML, why are the xlst (saxon, xalan) transformers
complaining about duplicated startDocument elements? Sure you can use a
parser to create Sax events within a transformer java class which
extends the AbstractSAXTransformer class?
Thanks again,
Ant

Hah. Thanks for that. I suspected it was something simple like that.

RE: Simple question
Thanks Ron, I'll take a look. Upayavira - I have little experience with Cocoon so I cannot comment on a better Cocoon oriented way yet. The servlet itself will eventually be invoked from HTML forms and will do things such as authentication and queries to databases - so I just needed to know how to call this servlet correctly in a pipeline.

I simply want to invoke a servlet which lists lots of debug information about our current environment (e.g. application context and DB related configs). It's just a starter to ensure all the expected environment parameters are correct. Okay. So how would that servlet interact with the rest of Cocoon? Does it need to be called via doGet(), i.e. does it need an HTTPRequest and HTTPResponse to be working with? Also, what does it expect to do with its output? Do you just want to write that to the logs, or have Cocoon output it? Would you consider a more Cocoon oriented way of achieving the same effect? Sorry to keep asking questions!

RE: Simple question
Just had a look in Cocoon 2.1.7 - doesn't seem to have the status.html example?

RE: Simple question
Ahh, found it thanks (bare with a Cocoon newbie here) Still doesn't show how I invoke a servlet in the sitemap though :-( Sorry for being dumb.

Go to http://localhost:, click on samples, then, in the middle, on the right, you'll see System Tools and Pages. Beneath that is status page. Have you built Cocoon with samples included?
