Problem Getting Started...
Hello!
I'm new in the ML and in the Lucene world in general... :)
I re-installed JDK after a very long period in order to start using
Lucene but I had problems after few minutes I finished installing Java
and Lucene.
I installed:
JDK 1.5.0_06
Lucene 1.4.3
I've set the environment variables as follows:
PATH: C:\Sun\AppServer\bin; C:\Programmi\Java\jdk1.5.0_06\bin;
CLASSPATH: .; C:\Programmi\QuickTime\QTSystem\QTJava.zip;
C:\Programmi\lucene-1.4.3\lucene-1.4.3.jar;
C:\Programmi\lucene-1.4.3\lucene-demos-1.4.3.jar;
I then tried to follow the instructions found at
http://lucene.apache.org/java/docs/demo.html
so I opened a command prompt and typed: "java
org.apache.lucene.demo.IndexFiles C:\Programmi\lucene-1.4.3\src" and I
got the error "xception in thread "main" ... NoClassDefFound
org/apache/lucene/demo/IndexFiles" which means that it didn't find the
class definition.... But where is my mistake?
Can anybody help me pleeeeeeeease?? :)
Thanks a lot for your attention and, I hope, your help! :)
Bye, Federico

Hi,
I had the same problem at the beginning.
Try
java -classpath lucene-1.4-final.jar; lucene-demos-1.4-final.jar;
org.apache.lucene.demo.IndexHTML -create -index webindex docs
If this fails go in the org/apache/lucene/demo directory and compile
IndexHTML.java with the command
javac -classpath lucene-1.4-final.jar;lucene-demos-1.4-final.jar;
org.apache.lucene.demo.IndexHTML.java
and then retry the first step out of this mail.
Greetings
Gaston

Are you running the Sun JVM? Or some other JVM?

Mailing List! ehehe! :)
this morning i changed some settings for the PATH variabile, but I'm
still experiencing the same trouble. I tried to extract lucene
following the hints given in the appendix of "lucene in action" (I've
that book) but without success... I downloaded lucene-1.4-final.zip,
extracted to C:\lucene-1.4-final\ and updated the classpath of
windows. Somebody told me to set the JVM classpath by typing:
java -cp lucene-1.4-final.jar; -jar lucene-demos-1.4-final.jar
but I got the following message:
Failed to load Main-Class manifest attribute from lucene-demos-1.4-final.jar
While when i Try to set the classpath as suggested in the appendix
(java -cp lucene-1.4-final.jar; lucene-demos-1.4-final.jar) i got the
"usual" Exception in thread "main"...
Does anybody know the solution to my problem please? :)
Thanks again! Bye

Federico,
I'm pasting below the relevant piece of the "Installing Lucene"
appendix, I hope this helps. At first glance, the environment and
steps you described seemed fine, so I'm not sure what is awry.
I hope the info below helps:
Running the command-line demo
The command-line Lucene demo consists of two command-line programs: one
that indexes a directory tree of files and another that provides a
simple search
interface. To run this demo, set your current working directory to
the directory
where the binary distribution was expanded. Next, run the IndexFiles
program
like this:
java -cp lucene-1.4.2.jar;lucene-demos-1.4.2.jar
org.apache.lucene.demo.IndexFiles docs
.
.
.
adding docs/queryparsersyntax.html
adding docs/resources.html
adding docs/systemproperties.html
adding docs/whoweare.html
9454 total milliseconds
This command indexes the entire docs directory tree (339 files in our
case) into
an index stored in the index subdirectory of the location where you
executed
the command.
NOTE Literally every file in the docs directory tree is indexed,
including .gif
and .jpg files. None of the files are parsed; instead, each file is
indexed
by streaming its bytes into StandardAnalyzer.
To search the index just created, execute SearchFiles in this manner:
java -cp lucene-1.4.2.jar;lucene-demos-1.4.2.jar
org.apache.lucene.demo.SearchFiles
Query: IndexSearcher AND QueryParser
Searching for: +indexsearcher +queryparser
10 total matching documents
0. docs/api/index-all.html
1. docs/api/allclasses-frame.html
2. docs/api/allclasses-noframe.html
3. docs/api/org/apache/lucene/search/class-use/Query.html
4. docs/api/overview-summary.html
5. docs/api/overview-tree.html
6. docs/demo2.html
7. docs/demo4.html
8. docs/api/org/apache/lucene/search/package-summary.html
9. docs/api/org/apache/lucene/search/package-tree.html
SearchFiles prompts interactively with Query:. QueryParser is used
with Standard-
Analyzer to create a Query. A maximum of 10 hits are shown at a time;
if there are
more, you can page through them. Press Ctrl-C to exit the program.
