AbstractAnnotationAction for Cocoon 2.x
Hi.
I've written a simple class which may help others writing Actions with
lesser code. Feel free to use it (and expand it) if you like it.
An example:
public class TestAction extends AbstractAnnotationAction {
@ActionMethod
protected void doMyAction (@SitemapParam(my-param)
@DefaultValue(true) boolean myParam,
@QueryParam(login) String
login,
@QueryParam(counter)
@DefaultValue(0) int counter;
Session session) {
System.out.println (Login: +login);
}
}
You can use @QueryParam, @SitemapParam, @ConfParam, @HeaderParam,
@CookieParam, @FileParam. In the signature of the method you can just
add variables if you need them: Request, Session, Redirector, Response,
ResultHashMap, Conext, SourceResolver. All of them will be set
automatically.
All parameters are casted when needed.
The method to be invoked must have a @ActionMethod annotation or you can
define the method using _method request or sitemap parameter.
Cheers,
Jörn

Re: XSLT transformation
Just remember that XML Spy does not use the same XSLT transformer as Cocoon. I think there is an error in your stylesheet. Try to comment out some parts of it to find the lines which causes the error. JOERN Antony Grinyer schrieb: Hi, A have a simple sitemap entry as below: map:match pattern=listcontainers map:generate type=file src=content/showsyscontainer.xml/ map:transform type=bdbxml/ map:transform type=xslt src=style/xsl/containerslist.xsl/ map:serialize type=html/ /map:match The generator is a simple XML file which is passed to a java class transformer ( referenced as type=bdbxml) which returns XML results. This all works fine if I use map:serialize type=xml/ to simply output the XML, however if I try to transform the XML output with the XSLT transformer above I get an error: Error executing pipeline. org.apache.cocoon.ProcessingException: Error executing pipeline.: java.lang.RuntimeException I know the XSLT containerslist.xsl is correct as I've tried it against some sample output XML in XMLSpy, but it appears that when I add this XSLT transformer I get a Processing Exception? In the sitemap.log it is reported as: Unable to get parser: java.lang.RuntimeException: java.lang.NullPointerException Any ideas please?

outputBufferSize problem
Hello.
I've used
map:pipeline
map:parameter name=outputBufferSize value=1/
and
map:pipes default=noncaching
map:pipe name=noncaching
src=org.apache.cocoon.components.pipeline.impl.NonCachingProcessingPipeline
parameter name=outputBufferSize value=1/
to realize, that the output of a XSP file will be send to the client
directly, without any caching.
I used the following XSP to test it:
xsp:page language=java xmlns:xsp=http://apache.org/xsp;
html
head
/head
body
div id=dataText/div
xsp:logic
try { Thread.sleep (3000); } catch (Exception ex) {}
/xsp:logic
script language=JavaScript
document.getElementById ('data').innerHTML = 'Test-Row 1';
/script
xsp:logic
try { Thread.sleep (3000); } catch (Exception ex) {}
/xsp:logic
script language=JavaScript
document.getElementById ('data').innerHTML = 'Test-Row 2';
/script
xsp:logic
try { Thread.sleep (3000); } catch (Exception ex) {}
/xsp:logic
script language=JavaScript
document.getElementById ('data').innerHTML = 'Test-Row 3';
/script
/body
/html
/xsp:page
Well, the page will be displayed 15s after asking the server...
Does anybody know the reason?
I'm using Cocoon 2.1.6 and Resin 3.0.10 on Win XP.

AW: Running Cocoon from CD
What about using Jetty? You can write your own startup app which launches Jetty+Cocoon, even as an autostart-exe which uses a jre on the cd (which might be a little bit slow). -Ursprüngliche Nachricht- Von: Michael Faschinger [mailto:[EMAIL PROTECTED] Gesendet: Donnerstag, 22.

Tomcat works perfectly fine but cocoon won't work as it tries to write some files (WEB-INF\db\commondb.*) to the CD. Is there a way to avoid this? Are there any further problems that might appear?

Solution for Protecting Cocoon Apps
Background: If you want to gíve customers your application (e.g. for a demo, proof-of-concept, discussion) you habe to include source code, everybody can see as plain text. If one of your customer has evil intensions he can look at all interna of your application, e.g. XSL-stylesheets, SVG data, the sitemap or XML files with private data. Idea: Protect some files from read directly from the file system. When running Cocoon, it should decrypt those files without having to change any code of the Java apps (Cocoon, Tomcat, Jetty, whatever). Solution: To do so, you can replace the java.io.FileInputStream class with one you can easily extend. E.g. via looking for the file extension and if it's .xmap decrypt the file. You can easily crypt those files before building the demo. The problem is that java.io.FileInputStream uses native methods so that you cannot change the file directly. But you can write your own WrappedFileInputStream which uses it's own native methods. The shared library acts like a wrapper, so calling WrappedFileInputStream.open() will forward the call to FileInputStream.open(). If you've done that, your own FileInputStream can extend WrappedFileInputStream and decrypt files as needed. You can then use -Xbootclasspath to replace the JDK's FileInputStream with your version. I've done so with Jetty, Cocoon, J2SE 1.4.2 on Win32 and it worked. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

But the problem is everybody can see the internals of the app. All the pipelines in sitemap.xmap, all XSL and XML. It can be used to find backdoors in the sitemap for example. So the question is, how to protect files from being read directly. A solution would probably be to encrypt (for example via XOR) all the files. After that, Cocoon (Jetty) has to be started with modified Java-IO classes (via bootclasspath). Does anybody know which classes have to be changed or if there's somebody who has done something like that...

Calling a pipeline without triggering through a URL
Hi. I want to save the output of a pipeline using a schedule class. E.g. saving an excel file every hour automatically. An approch would be to call the specific URL (e.g. http://localhost/get-excel-sheet.xls) but as I use a login-prompt I have to call serveral pages before. So, there must be a better way. I need something like calling cocon://get-excel-sheet.xls but as it is not triggered by a browser I do not have a context map. So, is there a way to use the Cocoon servlet class or something static (or whatever) where I can call the specific pipeline? Hope I have explained it understandable...
