Subject: Re: [docbook] More memory for Lucene

Hi Thomas,

I'll investigate how our catalogs are set up on the documentation


On the documentation server, for the same document, I see this:

Indexed the contents in 3116 seconds

That's 51 minutes!

Could it be that the you miss some JAR files in your classpath? Can you
check if both are the same?

I use the exact same tools both on my local computer and on the documentation server.

The big Java command, including the configuration for that command, is a copy from the sample Makefile provided with the 1.78.0 style sheets (provided as webhelp/Makefile.sample). Here is the configuration:

INDEXER_JAR   := $(DOCBOOK_EXTENSIONS_DIR)/webhelpindexer.jar
TAGSOUP_JAR   := $(DOCBOOK_EXTENSIONS_DIR)/tagsoup-1.2.1.jar
LUCENE_ANALYZER_JAR := $(DOCBOOK_EXTENSIONS_DIR)/lucene-analyzers-3.0.0.jar
LUCENE_CORE_JAR   := $(DOCBOOK_EXTENSIONS_DIR)/lucene-core-3.0.0.jar

If there's something missing, it's missing in the 1.78.0 style sheets, too.

This line makes me suspicious:

-classpath ../../mysqldoc-toolset/xsl.d/docbook-xsl-1.78.0/extensions/webhelpindexer.jar:../../mysqldoc-toolset/xsl.d/docbook-xsl-1.78.0/extensions/tagsoup-1.2.1.jar:../../mysqldoc-toolset/xsl.d/docbook-xsl-1.78.0/extensions/lucene-analyzers-3.0.0.jar:../../mysqldoc-toolset/xsl.d/docbook-xsl-1.78.0/extensions/lucene-core-3.0.0.jar

I would have expected to see the xml-commons-resolver jar. It seems
it's not there. This jar is responsible for XML catalog resolution
and if you don't have that, your tools will load them from the

That's interesting. Our documentation server runs behind a firewall, and while it does have access to the internet, I suspect it's low-bandwidth. So, indeed, this could be responsible for the huge index creation time we get on that machine.

As I said initially, we're using the Java tools shipped with the 1.78.0 style sheets in the extensions directory. That directory contains these JAR files (in other words, it doesn't contain xml-commons-resolver.jar):

xsl.d/docbook-xsl-1.78.0/extensions> ls -1 *jar

Regarding xml-commons-resolver.jar, it's installed (with xml-commons) on my computer and on the documentation server. Could it be possible that it's (implicitly) used on my computer, but not on the documentation server?
