NullPointerException in JTidy or HTMLGenerator
Dear Cocooners,
I'm trying to get the CLI working to generate static web sites.
We're using Cocoon v. 2.0.5-dev (mistake?).
Things seem to fail in HTMLGenerator and/or jtidy; no static
content gets generated. Anybody know of a fix?
I've got a batch file running, run.bat, to start the CLI.
My command line is:
$ ./run.bat -c . -C WEB-INF/cocoon.xconf -d tmp -f urlfile.txt > CLI-out.txt
I get a java.sql.SQLException saying the database is already in use by
another process, but I assume I can ignore that since I'm not using any
database.
urlfile.txt contains one URL, "mount/gem/workbench/About/Home", which
works fine when I use it from a browser to connect to Cocoon.
Looking at the debug output in CLI.txt, it seems that the URL is getting
interpreted right by the sitemap, but at some point the process crashes
with a NullPointerException in org.apache.xml.utils.AttList.getValue(AttList.java:247)
which is being called by HTMLGenerator. Here's the error message in context
(for the entire debug output, see http://www.huttar.net/lars-kathy/tmp/CLI-out.txt
[0.5MB]).

============================== end of excerpt =========================
I checked the destination directory, ./tmp, and it was empty.
Nothing got generated.
Any ideas?
Surely the whole process isn't crashing just because my HTML lacks
a <title> element? (No, actually I went back just now and added a title
element to that web page, and got rid of the title element warning,
but still have the same jtidy error and NullPointerException.)
The relevant sitemap, mount/gem/sitemap.xmap, can be perused at
http://www.huttar.net/lars-kathy/tmp/sitemap.xmap
The HTML file being accessed, Home.htm, is in the same directory.
Thanks for any help!
Lars

Re: xsp: returning nodes
Posted by Antonio Gallardo <ag...@agsoftware.dnsalias.com>.
If you have the control of the function, then you can use:
org.w3c.dom.DocumentFragment
Info about this interface you can find here:
http://xml.apache.org/xerces-j/apiDocs/org/w3c/dom/DocumentFragment.html
I would help if you can explain more about what are you trying to do.
Best Regards,
Antonio Gallardo.

xsp: returning nodes
Posted by Michael Hohmann <mi...@gmx.de>.
Hi all,
I want an xml-structure that is returned by a function as String to be
maintained as xml and not to be treated as text.
I tried it like this:
<xsp:logic>
String noder(void)
{Return("<test>testvalue</test>");}
</xsp:logic>
<xsp:page>
<xsp:expr>noder()</xsp:expr>
</xsp:page>
The node should appear as node in the resulting xml from the logicsheet,
so a stylesheet would be able to transform it later in the pipeline.
I expected the reply from the logicsheet in the browser to look like:
<xml>
<test>testvalue</test>
But what happens is that the thing returns things like:
<xml>
<test>testvalue</test>
Can anyone help?
Thanks....
Michael

With a bit of guidance, it isn't that hard!

Thanks for taking a look at the problem.
I'm downloading 2.1 now to see if it works better for me.
I have just started using Eclipse, but had not thought to try
debugging Cocoon with it. If I do find anything I'll let you know,
but I know so little about the inner workings of Cocoon (or even
the outer workings) that it seems unlikely.

Lars,
It seems that it is failing at the point where it tries to find if
you've got an href attribute present in your site. Although I cannot see
why it should do that.
If you're able, switch to 2.1, as it has a lot more functionality. For
example, changing one option can double the speed of CLI generation.
Also, I'll be more in a position to support its use, as I know it far
better.
Try it, and see whether you can get your site to work.
If you're unable, are you comfortable working in a debugger? Try loading
Cocoon in an IDE such as Eclipse and set a breakpoint at line 81 in
ExtendedXLinkPipe, and see if you can work out what is going on there.
If you do find a bug, I'll happily commit a patch.
HTH.
