FAO Otis Gospodnetic
Was there any more articles liek this written. I found them extremely useful for getting an in depth understanding of how Lucenes indexing system worked. Is there a corresponding set for Lucenes search functionality. The recommendations from other Lucene users were useful, but didn't go to the same detail as these 2 articles(which is what i'm looking for!) Does anybody know of any other docs that go into detail on the functionality of Lucenes search? Thx for the advice peeps. ian :) --- Daniel Mnard [EMAIL PROTECTED] wrote: I also found these two articles http://www.onjava.com/pub/a/onjava/2003/01/15/lucene.html http://www.onjava.com/pub/a/onjava/2003/03/05/lucene.html from Otis Gospodnetic very usefull for me.

Is this done simply by saying: String indexDirectory = /path of directory you want index to be stored in Ian _ Sign up for FREE email from SpinnersCity Online Dance Magazine Vortal at http://www.spinnerscity.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Extracting Lucene onto Tomcat
Is the package information and import paths ready to deploy on Tomcat server. I tried extracting lucene on the server, but when i compile files, it just throws numerous no class definition errors and errors relating to the package.

Re: Extracting Lucene onto Tomcat
Well when i extracted it, it created the org/apache/lucene directories in the public_html directory. When i try to compile any of the source it just throws numerous errors. I've got the classpath set to web-inf/classes. Have i extraced it to the wrong directory? --- Erik Hatcher [EMAIL PROTECTED] wrote: On Jul 21, 2004, at 8:10 AM, Ian McDonnell wrote: Is the package information and import paths ready to deploy on Tomcat server.

Lucene certainly deploys just fine in Tomcat web applications (in a WAR under WEB-INF/lib). Could you elaborate on what you mean here?

Re: Extracting Lucene onto Tomcat
I was looking at your instructions there, but couldnt really figure out what you mean. Can i manually add the extracted directories onto the tomcat server, if so what should my root directory be? Say for example the extracted directories org/apache/lucene/ Should i have that as public_html/WEB-INF/org/apache/lucene?

Re: Extracting Lucene onto Tomcat
No sorry i didnt mean that i was trying to extract the jars at all. I meant the extraction of the original lucene source bundle. I have been developing in java for going on 5 years now, but am relatively new to Web Apps. I have some experience in TomCat from days as an undergrad and do understand that perhaps the questions i'm asking wernt exactly tech questions relating to Lucene, but rather Tomcat related enquiries. I think the reason i was struggling was that i havn't been able to locate the lucene war files as they dont seem to have come as part of the latest source drops. Thx for the advice and hopefully you can help me out when i'm further into the development process. Ian --- Erik Hatcher [EMAIL PROTECTED] wrote: There is no need to extract Lucene's JAR file. Your questions indicate that you have some Tomcat and Java web application learning to do and this forum is not the most appropriate place to ask. Lucene includes a web application demo that you could try deploying by following the steps here: http://jakarta.apache.org/lucene/docs/demo3.html Just drop luceneweb.jar into CATALINA_HOME/webapps, restart Tomcat and try hitting http://localhost:8080/luceneweb and pressing the search button - you will get an error unless you've followed all the steps, but you should not get a class cast exception and Lucene will be working properly (now follow the steps to build an index and configure the pointer to it).

Can Lucenes indexer be used to store info in fields in a mysql db? If so can anybody point me to an example or some documentation relating to it.

Re: The indexer
Basically i add details about a movie clip as various fields in an sql db using a jsp form. When the form submits i want to add the details into the db and also want the fields to be stored as a searchable lucene index on the server. Is this possible?

I'm not quite clear on your question. You want to store a Lucene index (aka Directory) within mysql? Or, you want to index data from your existing mysql database into a Lucene index? A Directory implementation for Berkeley DB was created by the Chandler project and contributed to the Lucene sandbox (see Lucene's website for details on the sandbox and how to get to it).

Re: The indexer
Yeah that last part of your reply seems to be what i'm trying to do(you're going to have to excuse me as i'm a total newbie to Lucene and am only finding my feet with it). I searched the archives and went back through it manually just there, but didnt find any relevant posts in the archive. As for indexing data from mysql - there have been lots of discussions of that recently, so check the archives. Basically you read the data, and index it with Lucene's API. And you are responsible for keeping it in sync. The problem i am having is reading the data from the sql tables and then using the indexer to store it. Has anybody indexed from a mysql table before? If so, do i need to create some kind of JDBC query that selects all the field values from the table and indexes them in a lucene document that is stored on the server? If i do this, how can this process be automated rather than manually running the program everytime a new profile is added via the jsp form? Erik, i'm not sure what you mean about keeping the db in sync. Are you talking about stale or updated db entries?
