Whats wrong?

Hi,

Post by Jürgen Niehoff
http://xml.org/sax/properties/lexical-handler

your CLASSPATH contains the crimson XML parser which is loaded before Xerces.
The exception is generated because crimson does not support the
lexical-handler property. I would suggest to check your CLASSPATH and remove
crimson.

Regards,

Wolfgang

Hi,

output of build, server.sh and startup.sh looks good. The
NoClassDefFoundError during build is ok, because you don't need the Antlr
parser generator unless you are changing the parser.

You may also ignore tomcat's error message "cannot load servlet name: jsp". I
can't suppress this message, but it does not do any harm, because eXist
doesn't use jsp.

Have you tried to access http://localhost:8080/exist/index.xml, query.xml?

Regards,

Wolfgang

Hi again,
i removed crimson, but then eXist doesn't start. I attached a file, which
contains the build, server.sh and startup.sh output. Perhaps you can see
whats wrong?

P.S.: i removed "crimson.jar" to the original place again
(/usr/lib/jdk1.3/jre/lib/ext/)

Another idea: Maybe you're using jdk1.4? It comes with it's own XML parser,
which is crimson. I guess, you have to use JDK1.3 or define which parser to
use. See Java JAXP docs.

I've hit a new problem with eXist 0.7b2 on Mandrake 8.1

After working fine for several hours, the server suddenly starts returning
the same error to all queries (whether via java command-line, XML-RPC or
httpd) I have verified that it is a server problem, rather than my data, by
preparing scripts with the queries "pre-cooked". The same scripts that work
fine when the server is behaving itself all start to fail once the
malfunction begins.

Output is
<exist:result xmlns:exist="http://exist.sourceforge.net/NS/exist"
hitCount="0" err
code="6"><exist:message>java.lang.ArrayIndexOutOfBoundsException</exist:mess
age></
exist:result>

A typical server log:

Stopping and starting the server doesn't help. If find I have to stop the
server, and reindex all the documents with the -l switch via the java
command-line interface. Once that's done, everything works again for another
few hours.

Any suggestions?

few hours.

In addition, I find I have to delete the entire contents of exists /data
directory before reindexing the document.

IN case it's of any interest, resending the exact same query once the
document has been reindexed produces the following from the server logs
instead of the error messages and stack trace in my earlier message

After which the expected results are returned instead of the previous error
return.

Hi,

this seems to be a bug in the btree and storage classes. All "tid not found" messages indicate that one of the pointers used to connect btree values with data records is broken. Have you done lots of removals, updates or just queries?
