lia demos without ant

Hallo,


IBecause of less or better say no experience in Ant I try to run some demo applications out of the LuceneInAction Examples folder. For example I wanted to test AnalyzerDemo.java. I set the -classpath c:/LuceneInAction/lia/analysis because there is AnalyzerDemo.java on my system. I tried to compile it with :
 java -classpath lucene-1.4.3.jar lia.analysis.AnalyzerDemo but it failed. The error is NoClassDefError.
Has somebody a hint why it fails


Thanks in advance



Greetings



Gaston

Hi Gasi,

Please see page xxxii in LIA, section Author Online, and use that for
LIA questions, so we don't bother others with LIA-specific stuff.

However, your problem doesn't have to do so much with LIA, either. 
It's a basic Java question, and it looks like the part that you have
been misunderstanding is about what CLASSPATH is or how it is used.

When you run "java -classpath lucene-1.4.3.jar
lia.analysis.AnalyzerDemo", you are not compiling anything, you are
trying to run AnalyzerDemo class, in the lia.analysis java package.

Also, thar particular command assumes that file lucene-1.4.3.jar is in
your current directory, and based on your error, it looks like that's
not the case.

Here are some links that may be worth checking out:
