[Dspace-tech] javax.swing.text.html.HTMLEditorKit Missing when Running filter-media

[penni...@rhodes.edu]

I've been evaluating DSpace 1.4 and am impressed in how far it has come
since I first looked at it in 2003. I have been able to get it
successfully compiled and installed and running under Tomcat.

However, I am running into a problem getting thumbnails to generate
using filter-media. When I run filter-media, I get an error that appears
to say that the javax.swing.text.html.HTMLEditorKit class is missing
(error message below). We are running the Java 1.5.0.06 JDK. Is it
possible that this Swing class is not included?

We are using ant 1.6.5, so that should be OK. DSpace builds and runs in
Tomcat correctly; the problem is just with filter-media. Any ideas?
Should I try a newer/different J2EE engine?

Thanks in advance for any help...

The last time I saw this problem it was because despite having the Sun
JDK installed, my system was still using the Gnu Java implementation
that comes with some distributions. I believe the clue is here ....

^^^^^^^^^^^^^^

Check that your user profile is pointing to the right path for the Sun
JDK, as the Gnu implementation doesn't have replacements for the swing
libraries.

Cheers,

Richard, thanks a bunch for pointing me in the correct direction. Yes,
indeed, I'm running Redhat EL 4, and my /usr/bin/java symbolic links was
not pointing to the correct java app. (RHEL4 puts these java symbolic
links in the /etc/alternatives directory, and you can change them there
to point to your real java home directories and binaries.)

Now, however, I'm getting a different error when I run filter-media

[bin]$ /dspace/bin/filter-media

This error seems pretty straightforward: the
org.dspace.app.mediafilter.WordFilter class file cannot be found.
However, it was compiled and put into the dspace .war file and is
available in Tomcat here:

/usr/local/tomcat/webapps/dspace/WEB-INF/classes/org/dspace/app/mediafil
ter/WordFilter.class

Should it be somewhere else? Do I need to rebuild DSpace after changing
what /usr/bin/java is set to?

Thanks in advance for any help...

Actually, no. The class that it can't find is #. For some reason, the
WordFilter class is attempting to magically discover what the class it
is working with is, only to discover that # (the class that it thinks
it finds) is actually not a class at all. Sounds almost like the wrong
data is being passed to the wrong class. Maybe a nonexistent plugin is
being called? Someone with a bit more filter-media experience might
want to weigh in here.

Hi Stacy,

Have a look in your dspace.cfg file, and check for a hash '#' before the
line that contains org.dspace.app.mediafilter.WordFilter

I'm guessing you might have something like:

plugin.sequence.org.dspace.app.mediafilter.MediaFilter = \
org.dspace.app.mediafilter.PDFFilter, \
org.dspace.app.mediafilter.HTMLFilter, \
# org.dspace.app.mediafilter.WordFilter

Normally java ignores lines beginning with a hash, but in this case,
because the line before terminates with a slash '\', it looks for more
detail on the next line.

Thanks,


Stuart

I'm in the same situation, running RHEL4. What did you end up pointing
your /etc/alternatives/java at? Mine is:

lrwxrwxrwx 1 root root 30 Oct 18 13:46 /etc/alternatives/java
-> /usr/java/jre1.5.0_08/bin/java

Though I did notice that, with gcc4,

[root@dspacetest ~]# locate HTMLEditorKit
/usr/lib/gcc/i386-redhat-linux/4.1.0/include/javax/swing/text/html/HTMLEditorKit.h

I'm seeing plenty of "You do not have permission to extract text"
errors, but none of the above. Hmm... Is it producing any text files
at all, that is, are you getting any output like the following?

FILTERED: bitstream 1114 and created 'ch7.pdf.txt'

This is the expected behavior, correct? I'm guessing: PDFs with locked content?

Jonathan,

Thanks, you nailed it. The problem was that my dspace.cfg was having
issues with the line listing the mediafilters to use. Once I look out
the line wrap characters and just put all of the filters on one line,
filter-media immediately worked and now I see thumbnails.

Thanks again for the help...

I'm not sure whether you can do this without using the Lucene API. You
can kind of check by specifying the dspace.cfg index field name as part
of the search (e.g. by entering 'keyword:holocene' in the general search
box you can limit the search for holocene to the keyword field). Do you
know what metadata may be being erroneously indexed? One thing to also
consider is if you have run the filter-media job and extracted text from
PDF/HTML/Word, that text is also indexed.
