Cocoon Caching
Is there a good document out thr that details how Cocoon Caching works???
The only one that I could find was:
http://cocoon.apache.org/2.0/userdocs/concepts/caching.html
thanks

Re: Cocoon Caching
Posted by Edward S <su...@gmail.com>.
As per the document, I created a cocoon generator and implemented the
CacheableProcessingComponent
interface.
As stated, 2 methods should be implemented:
1] getKey()
2] getValidity()
I created an object, that had all the request parameters along with the URI.
Made that object serializable and set that one as te key.
Similarly, I created another object that implemented SourceValidity and
returned that object from the getValidty method.
However, when I run thru the pipeline... its never adds anything to the
cache neither it returns anything back from the cache.
any thots on where I am going wrong??

I don't see anything obviously wrong with your Java from Javascript
calls.
Looking at some of my scripts, I see I follow cocoon.senPage() with a
cocoon.exit() call.
I sort-of recall getting an error without this in some cases, but I
don't recall what sort of error.
Some other general debugging tips:
You can run your javascripts using rhino from the shell.
The cocoon object doesn't exist and there are some other
environment differences,
but you can easily test the Date classes:
$ java -jar /usr/local/java/rhino1_6R5/js.jar
Rhino 1.6 release 5 2006 11 18
js> var d = new java.util.Date();
js> d
Wed Jul 25 15:49:43 EDT 2007
js> d.year
107
js> d.year = 103
103
js> d
Fri Jul 25 15:49:43 EDT 2003
js> d.year = 2003
2003
js> d
Sat Jul 25 15:49:43 EDT 3903
js> ^D
I see that the year values are actually - 1900.
Looking at my java docs, I see that Date.getYear is marked as
deprecated.
Perhaps this is a problem if you are running Java 1.6
( I'm still using 1.5, so that's just a guess. )
You might also try adding some cocoon.log.info() calls to write
debugging info
to the cocoon log file.
A more complete example is included below at bottom.
( But, as noted, I don't think that is your problem. )
[ Example is a redirector I use to punt around the non-working
unparsed-entity-uri() in cocoon problem by resolving the
entities outside of cocoon's SAX event pipeline. ]

Check your cocoon.log file (it's in WEB-INF/logs/ if you didn't change
its location; you can change its location in WEB-INF/logkit.xconf)
Look for the useless error message about "Compilation produced 1 syntax
error" and a couple lines above you will find the real message with
error type, line and column.

Simple Java from flowscript ?
Posted by "Schmitz, Jeffrey A" <Je...@boeing.com>.
Hello,
I've tried to call java from my flowscript as shown here:
http://cocoon.apache.org/2.1/userdocs/flow/java.html
However, I get a compilation error when I try to load my webpage. First,
is there anywhere to see specifics about the compilation error
encountered? All it tells me is Compilation produced 1 syntax error on
line 1.
Also, are there any more complete examples of calling java from
flowscript?
And finally, any ideas on what may be wrong?
Here's my main flowscript function, which otherwise works until I add
the java Date stuff:
function main()
{
var d = new java.util.Date();
d.year = 2003; // same effect as d.setYear(2003);
getInfo();
upload();
var uri = neutralInstModel "/" + inputType + "In/" + inputFile + "/"
+ inputType + "In.trans/" + cocoon.continuation.id;
cocoon.sendPage(uri);
}
And here's my flow-interpreters entry in cocoon.xcon:
<flow-interpreters default="javascript" logger="flow">
<!-- FOM (Flow Object Model) -->
<component-instance
class="org.apache.cocoon.components.flow.javascript.fom.FOM_JavaScriptIn
terpreter" name="javascript">

Thanks!

There is a 2.1 version as well [1]. There is also a wiki page [2], for
what it's worth. For more information you need to dive into the code I'm
afraid.
