thanks for the tip. i'd already stumbled across that and it's a very good
solution. still, the underlying problem though seems like a bug and oughta
be fixed or at least noted. according to the system identifer notes from
the xml spec:

http://www.w3.org/TR/REC-xml#dt-sysid

"Unless otherwise provided by information outside the scope of this
specification (e.g. a special XML element type defined by a particular
DTD, or a processing instruction defined by a particular application
specification), relative URIs are relative to the location of the resource
within which the entity declaration occurs."

the system identifier in this case is site absolute, e.g. "/foo/bar.dtd".
seems like it ought to be evaluated in the context of the url from which
the xml was retrieved.

you normally create a datasource with an appropriate name. the sample is

if you're looking for something easier to use in development, you might
try resin. it automatically reloads the webapps and/or itself when most
anything interesting changes.

you can use the xinclude or cinclude transformers, you can use the
sitemap's aggregation features, or you can probably do the inclusion
manually in an xsp page or even possibly still with the util logicsheet.

okay, guess i gotta figure out why it can't resolve the DTD then. fwiw,
the problem also occurs in the latest cvs build of c2. the stacktraces i
get are:

reason i'm missing, or is one of the resolver components not working as it

problems parsing xml from a foreign source in c2.0.0

[Donald Ball]

hey guys. i'm trying to retrieve some xml content over http to begin one
of my pipelines:

/nlm/query?author=Smith


  
http://www.ncbi.nlm.nih.gov/entrez/utils/pmqty.fcgi?db=PubMed&mode=XML&dispmax=999&term={1}[au]"/>

  


the xml returned from the nih server will begin like so:





unfortunately, cocoon tosses an exception when trying to parse this
document. it claims that it cannot access the dtd. however, it does not
appear that it's actually trying to get the DTD from the proper url:

http://www.ncbi.nlm.nih.gov/entrez/query/DTD/pmqty_020122.dtd

since the dtd is actually accessible at that url. it seems like the url
context information for the source xml is lost, which doesn't seem right.
anyone know what's up with that? is there another generator i should be
using?

as a workaround, i tried to figure out how to disable validation to ignore
the issue completely. well, it seems that in c2.0.0, you cannot configure
the parser's validation behavior in the cocoon.xconf file. i looked in the
source for JaxpParser, and was surprised to note the parser factory's are
configured to create non-validating parsers:

public JaxpParser ()
throws SAXException, ParserConfigurationException {
this.factory.setNamespaceAware(true);
this.factory.setValidating(false);
this.docfactory.setNamespaceAware(true);
this.docfactory.setValidating(false);
}

if this is right, why is the parser trying to validate?

Re: problems with cocoon-2.0.1 and resin-2.0.3

[Donald Ball]

one more bit of potentially useful information - when i start from scratch
with a clean webapp tree, i note that cocoon-files directory created in
the servlet's temporary work area, the only directories that are created
are cache-dir and upload-dir - the org directory which normally serves as
the root of the classpath for the dynamically generated sitemap and xsp
classes is never created.

so something seems to be going wrong when cocoon reaches the end of the
cocoon.xconf file and tries to load sitemap.xmap. i just tried copying in
the vanilla cocoon.xconf file from cocoon-2.0.1 and saw no change in
behavior (my only mods had been adding a client-specific logicsheet,
adding a data source, and changing the sitemap reloading to synchronous).

problems with cocoon-2.0.1 and resin-2.0.3

[Donald Ball]

hey guys. i thought i'd take the webapp that was causing the xsp engine to
hang in tomcat-4.0.2 with cocoon-2.0.1 and try it with resin-2.0.3
instead. interesting results...

when i copy the webapp into resin's webapps area while the resin server is
still running, it notices the new webapp, initializes and configures it,
and everything works fine. cool. however, when i stop and the start resin
again, the entire servlet engine hangs after it tries to initialize the
c2-based webapp.

the last line in resin's error log is:

[2002/02/28 02:11:11] DEBUG   (2002-02-28) 02:11.11:770   [cocoon  ]
(Unknown-UR
I) Unknown-thread/ThreadSafeComponentHandler: ComponentHandler initialized
for:
org.apache.avalon.excalibur.component.ExcaliburComponentSelector

nothing very interesting or out of the ordinary appears anywhere in that
log. nothing shows up in any of the cocoon logs except for the store
janitor stuff in the core log:

DEBUG   (2002-02-28) 02:12.20:621   [core.store-janitor] (Unknown-URI)

DEBUG   (2002-02-28) 02:12.20:621   [core.store-janitor] (Unknown-URI)
Unknown-thread/StoreJanitorImpl: Memory is low = false

and it does repeat itself periodically, losing 5-10k of free memory each
time. access, error, and sitemap logs are all blank. resin won't stop
normally, the java processes must be killed. looks like deadlock to me,
although why it only happens when the server is being started from scratch
is completely beyond me...

and of course, frustratingly enough, the c2.0.1 sample webapp works fine,
even its xsp pages. does anyone have any suggestions for where i might
begin debugging this?

problem isn't with c2 specifically, java is segfaulting when it tries to

i'm not aware of any way to do that in c2, unfortunately. i suppose it's
possible that one could write a TraxTransformer variant that would queue
its incoming sax events, scan for the xml-stylesheet PI and only get a
Transformer instance after it found out what stylesheet to use... but it
would be a chore, and the general feeling in the c2 crowd is that the job
of associating xml resources with stylesheets is best handled in the
central sitemap.

a question on xsp and a question on parameterizing xslt

[Donald Ball]

hi guys, long time no see. if anyone's curious where i've been, see the
apologetic post to cocoon-dev i just sent in. now, on to my questions. :)

1. a long while back, we had some discussion on whether or not one should
be able to send a redirect from an xsp page. i'd thought the eventual
consensus was that we should, but i guess i was wrong, since the response
logicsheet doesn't seem to provide any way to send a redirect, nor does
the Response interface provide a redirect method. however, one of the c2
docs _does_ reference such a method:

http://xml.apache.org/cocoon/userdocs/concepts/actions.html

compares and contrasts xsp pages and actions. the xsp page it contains has
the following snippet:


mypool

SELECT userid FROM users
WHERE name=name
AND password=password


userid = 








the alleged messiness of the code notwithstanding (;)), it seems to be a
common development idiom to want to redirect the user to a different url
or pipeline if something goes awry in an xsp page (the user can't login to
the database, the user doesn't have permission to do something, etc.) if
one cannot send a redirect from an xsp page in c2, can one switch
pipelines based on a flow control statement in an xsp page?

naturally, i can see that one could refactor and use actions to do the
pipeline switching and/or redirecting instead, but i still can't see any
good reason to prohibit early exit from a pipeline, via sendRedirect or
sendError from any component, including xsp pages. it's not always
desirable to factor to split the flow control stuff out of xsp pages into
actions. or is it?

2. in developing my own standalone j2ee webapps using trax, i quickly
realized that if you don't know at what url your webapp is going to be
mounted, you can't use absolute links to resources in your webapp, e.g.
images, javascript libraries, etc. but strictly using relative paths in
your xslt stylesheets when referencing those resources is not only a real
pita, it's impossible if that stylesheet if used in the construction of
urls that appear at different depths in the urlspace. the easy solution is
to parameterize the stylesheet with the context path information:




i presume c2 does not already parameterize stylesheets with this datum by
default. does anyone know how you would easily add that parameter to all,
or a certain class, of xslt transformations? also, i presume that others
have encountered this problem. is there an alternate solution anyone has
used that's better?

[c2.1] xsp question and a sitemap question

i want to give it a Pragma: No-cache HTTP header so that the client will

no, currently the xinclude parameters must exist in the xinclude element
as per the xinclude specification. i strongly oppose extending the
functionality of the xinclude transformer in that fashion - the xinclude
transformer attempts to implement the xinclude specification - no more, no

ee should not force any classes on its servlets other than the servlet
api. that being said, if you would like to contribute a patch to the
install docs with instructions for ee, that'd be sweet.

yes, easily, just use the standard xml-stylesheet pi - but you might want
to consider using c2. it allows for a more flexible mapping of urlspace to
xml-space and xsl-space. so to speak.

the xsp class loader is perhaps a bit broken. try putting your lib in the
tomcat shared lib directory.

they don't need to be, as long as you restrict yourself to method
variables and not class variables. i can't tell why your example wouldn't
work perfectly - maybe if you'd post your entire xsp page...?

that's invalid esql. the esql:results element must appear underneath an

you cannot pass a DOM from a servlet to cocoon unless you serialize it.
you can pass a DOM from another class to cocoon using a standard method
call.

cincludes can include sitemap uris. xincludes cannot. cincludes used to be
performed using the CIncludeSAXConnector, but i think it's disappeared at
the moment. XIncludes can be done using the xinclude transformer just like
you'd use any other transformer.

change the element name from 'foo' to 'include'. there's a bug in the way
xsp creates attributes with namespaces, and the clever workaround looks
for an element named 'include' with attributes named 'xinclude:href', etc.

(xsp:attribute assumes all whitespace is important - probably erroneously,
but you never know).

or if you just can't get that to work:


  

  

  


maybe see esxlt.org or xsltsl.sourceforge.net for a strip-whitespace
xslt function if you can't figure out how to make one.

i think you have to forcibly remove any jars containing DOM1 classes from
anywhere in the websphere installation. websphere, afaik, has never been
particularly good about giving its servlet zones a clean classpath to work
with.
