Hi.

I am also having problems with this demo.

I got around the missing tomcat directories by creating them first,
and copying the .jsp files and .war files over.

But it's a bit unclear as to whether the luceneweb.war file should be
in the {tomcat}/webapps or {tomcat}/webapps/luceneweb when
I try to execute "jar -uf luceneweb.war configuration.jsp". If its supposed
to be in the {tomcat}/webapps folder, then the above jar command
won't work because the configuration.jsp (which I had to copy over
from the lucene demo folder) file is in the {tomcat}/webapps/lucene
directory.

It also seems like you have to create an /opt/lucene/index folder.

When I run "java org.apache.lucene.demo.IndexHTML -create -index /opt/lucene/index",
I get a null pointer exception (using either JDK 1.2 or 1.3). I am running Red Hat 7.1,
with the Sun JDKs.

I set up this script to run it:
#!/bin/bash
/usr/java/jdk1.3.1_02/bin/java -verbose -cp /usr/java/lucene-1.2-rc3-bin/lucene-1.2-rc3.jar:/usr/java/lucene-1.2-rc3-bin/lucene-demos-1.2-rc3.jar org.apache.lucene.demo.IndexHTML -create -index /opt/lucene/index

And here is the (verbose--hope its not too much) output:

The UnknownHostException is probably because the parser
trying to read WEB-INF/web.xml wants to lookup the
dtd and is failing because it can't locate java.sun.com.
Perhaps suprising given your email address! Perhaps
you need to fix your local DNS setup so it can find
java.sun.com or use a different parser. I can't remember
all the ins and outs of this but I run tomcat off line,
without access to java.sun.com, using xerces.

Can't comment on the other stuff about the demo.

I'll take a look at the confusing instructions on demo3. I have no idea why
the dtd isn't validating. Can anyone else answer this?

You might want to pose the dtd problem to the tomcat-user mailing list. Due
note that I make the assumption you're using 4.0.x or know how to adapt it.
I'd guess if you take that top line and replace it with the top line from
one of the tomcat 3.2.x example web.xml files, you'll probably hit paydirt.
Probably tomcat can't read the newer format. (but the file is practically
blank anyhow).

I think that is correct. Tomcat 3.whatever understands

<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
"http://java.sun.com/dtd/web-app_2_2.dtd">

without recourse to any external sites, and Tomcat 4.whatever understands

<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">

but Tomcat 3 doesn't. So just edit web.xml and replace 3 with 2, twice.



Perhaps that should be noted in the demo docs if it isn't already.

Hi Don,

I fixed it.

It meant your {tomcat}/webapps directory. My proofreaders didn't catch
that ;-). The idea is to index everything you have mounted via tomcat.
(except for /ROOT which will be wrong as noted at the end)

Does tomcat 4 understand the 3.2.x header? If so, lets just use the
3.2.x header.

Hi Andy,

Thanks for clarifying the demo instructions!

Now, what about the NPE that Ken Munro cited (included below)? I'm
encountering this too:

dpg% cd $TOMCAT_HOME/webapps/
dpg% java -verbose org.apache.lucene.demo.IndexHTML -create -index
/opt/lucene/index
...
[Loaded java.io.RandomAccessFile from /usr/local/j2sdk1_3_1_02/jre/lib/rt.jar]
caught a class java.lang.NullPointerException
with message: null

Could that be related to the NPE problem discussed in the "PhraseQuery:
NullPointerException" thread, for which Ian offered a possible
solution, included here:

Looks like you need to include a file or directory name on the command
line as the last argument:

e.g. $ java ...IndexHTML -create -index /where/ever somefile.html

D'oh!

Thanks for pointing out that Ian!

I looked at the demo instructions again more closing and noticed that Andy
had specified ".." as the last argument:

java -verbose org.apache.lucene.demo.IndexHTML -create -index {index} ..

The command succeeds that way.

thanks again,

Hey Don,

My earlier correction was only half right. I read it over again, walked
through it and corrected it. The error you got below was because you
left off the directory at the end (in the instructions it was "..")..
I've clarified the instructions and corrected them... Thanks for
reporting these documentation bugs ;-).

-Andy
