Anyone have an ideas on how to index the contents within zip files?

Thanks,

Hello
first, you need a parser for each file type: pdf, txt, word, etc.
and use a java api to iterate zip content, see:
http://java.sun.com/j2se/1.4.2/docs/api/java/util/zip/ZipInputStream.html
use getNextEntry() method
little example:
ZipInputStream zis = new ZipInputStream(fileInputStream);
ZipEntry zipEntry;
while(zipEntry = zis.getNextEntry() != null){
   //use zipEntry to get name, etc.
   //get properly parser for current entry
   //use parser with zis (ZipInputStream)
}
good luck
Ernesto

Thanks Ernesto.

The issue I'm working with now (this is more lack of experience than
anything) is getting an input I can index. All my indexing classes (doc,
pdf, xml, ppt) take a File object as a parameter and return a Lucene
Document containing all the fields I need.

I'm struggling with how I can work with an  array of bytes  instead of a
Java File.

It would be easier to unzip the zip to a temp directory, parse the files and
than delete the directory. But this would greatly slow indexing and use up
disk space.

Luke

Luke,

Look at the javadocs for java.io.ByteArrayInputStream - it wraps a
byte array and makes it accessible as an InputStream.  Also see
java.util.zip.ZipFile.  You should be able to read and parse all
contents of the zip file in memory.
