Locationmap does not work with dispatcher

Post #1 of 8 (3280 views)

Hello,

I have a problem with dispatcher and I am still stuck with it. I am
trying to use forrest to convert documents from moinmoin format to TEI
format. I use locationmap.xml to search the pages in the remote wiki
server. The system is working correctly, producing TEI and HTML outputs.

However I would like to improve a little bit the result. I want to
introduce a new component in the final document that includes all the
links within the text. Some sort of "Reference" section. To do so I've
started to use dispatcher but with no luck.

When I activate the plugins for dispatcher in forrest.properties the
system does not work with locationmap. I am able to produce a TEI or a
HTML document from a moinmoin document, but only if it is located in
the content dir. But when I use try to use the remove server I obtain
different errors:

Message: null
Description: No details available.
Sender: org.apache.cocoon.servlet.CocoonServlet
Source: Cocoon Servlet
Request URI
wiki/CommunityTools.html

cause
dispatcherError: 500 - Internal server error
The contract "siteinfo-meta-navigation" has thrown thrown an exception
by resolving raw data from "cocoon://wiki/
CommunityTools.navigation.xml".
dispatcherErrorStack:

or

Message: Resource Not Found
Description: The requested resource "/wiki/CommunityTools.tei" could
not be found
Sender: org.apache.cocoon.servlet.CocoonServlet

I have looking to the documentation but I haven't found anything about
this particular issue. Any idea?

I configured forrest as follows:
forrest.properties:
project.required.plugins=org.apache.forrest.plugin.output.pdf,org.apache.forrest.plugin.input.simplifiedDocbook,org.apache.forrest.plugin.input.wiki,org.apache.forrest.plugin.output.tei,org.apache.forrest.plugin.internal.dispatcher,org.apache.forrest.themes.core,org.apache.forrest.plugin.output.inputModule

locationmap.xml:
<locationmap xmlns="http://apache.org/forrest/locationmap/1.0">
<components>
<matchers default="lm">
<matcher
name="lm"

src="org.apache.forrest.locationmap.WildcardLocationMapHintMatcher"/>
</matchers>
</components>
<locator>

<match pattern="project.wiki/**.moinwiki">
<location src="http://wiki.MYSERVER/{1}?action=raw" />
</match>

<match pattern="project.wiki/**.xml">
<location src="http://wiki.MYSERVER/{1}?
action=format&mimetype=xml/docbook" />
</match>
</locator>
</locationmap>

Regards,

Pablo

When you say you get different errors, is it predictable which error you
get?

You might want to install the forrestbar [1] (assuming you use Firefox)
this has a set of options that are really useful in debugging the
dispatcher. It helps understand what parts of a request are working and
which are failing.

Someone else might be able to help you with more targetted info.

It depends on the page I asking for and the document format. The error
I sent are for the same file with different formats. I still trying to
figure out if there is a fixed pattern.

I have one already installed but I was unable to get hints of it.

Let us see what the problem may be.

This error tells me that wiki/CommunityTools.navigation.xml cannot be
resolved.

Ross mentioned forrestbar, if you request above page and press
"dispatcher-dev -> Intermediate format"

what do you get?

Further what does wiki/CommunityTools.xml returns?

That does not seems to be the dispatcher but a general message from the
tei plugin.

seems to me the cause is a 404 file not found error now we need to track
down where and why it happens.

The Dispatcher is in development and issues with its
use should be discussed on the "dev" mailing list.
Most developers will have read your message here
so you can just refer to it.

IMO it is not a dispatcher problem at all.

However besides the wiki the other plugins used are in the whiteboard so
definitely a dev topic.

Thanks. I think your are right. Using yours tips I have been looking
around a little bit more to the communication between the wiki server
and the forrest instance. It seems the problem is there. With a new
local installation of moinmoin in my computer everything is working
smooth. My guess is I am being banned from the moinmoin wiki server
and it refuses to provide the correct page. I have spend hours trying
to figure out this, because the server always answer correctly to my
while I was connecting to it directly. I will look on this further.

I will move any other comment about dispatcher to the dev list.

Thank you again,

Pablo

This highlights a useful process in debugging that us devs take for
granted (I don't think we have ever actually documented it - we'd
welcome a patch to the debugging section in our FAQ).

When you find an unexpected problem, the first thing to do is to request

http://foo.org/bar.xml

This should return the internal XML format and allows one to narrow down
the problem to either the input or output stages, i.e. if it doesn't
return the XDoc document then it's a problem in the input stage, if it
does then the problem is in the output stage.

We'll give other hints out as people ask for them ;-)
