Mailing List Archive: Does Lucene really work with Java 1.1.8

I am trying to use the 'lucene-1.2-rc1.jar' with a WebObjects 4.5
application, but having problems. WebObjects uses Java 1.1.8. I read on the
jGuru Lucene FAQ that Lucene should work with this version of Java. Is this
correct?

If the latest version of Lucene only works with Java 1.2, can anyone tell me
if I can get an older version that works with Java 1.1.8?

The specific error I am getting is:

java.lang.NoSuchMethodError: java.io.File: method createNewFile()Z not found
at org.apache.lucene.index.IndexWriter.<init>(Unknown Source)
at org.apache.lucene.index.IndexWriter.<init>(Unknown Source)
at Application.createIndex(Application.java:38)
at Application.<init>(Application.java:15)

This occurs when I try to create an empty index with the following method:

public void createIndex() throws Exception {
String indexPath = "/Local/Users/jbrook/testIndex";
IndexWriter writer;

writer = new IndexWriter(indexPath, null, true);
writer.close();
}

It should, but it looks like it doesn't. I have logged a bug against this:
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=4049

I think this is worth fixing before a 1.2 final release is made. The
simplest approach is to turn off file-based locking in JDK 1.1.8. Is that
acceptable?

Note that that release is still in the com.lucene.* packages.
