RE: Help with Searching indexes from a web app (Lucene 1.3 rc2)
Well, I've fixed the problem.
I've upgraded tomcat to version 4.1.29 and it's all working again now,
(using exactly the same tomcat configuration etc as before). Seems as though
there is a compatibility problem of some sort with tomcat 4.0.3.
I am using the basic tomcat security on the webapp, but I wouldn't have
expected this to cause the problem, especially seeing as when I upgraded
tomcat to 4.1.29 the problem went away, (using the same security model).
Also, if it was a security problem, I'd had expected it to have trouble when
creating the indexes, not just when searching them.
At least it's working now
Thanks,
Iain

Also, reindex with the new API as well. There are likely
incompatibilities in the index format.

Subject: Help with Searching indexes from a web app (Lucene 1.3 rc2)
Hi folks.
I'm new to Lucene so this may be an obvious questions, but I am having
problems with Lucene 1.3-rc2. I've got a bit of code which looks
something
like this
public static void getSearchResults(String searchString, String
indexDir)
{
try
{
Searcher searcher = new IndexSearcher(indexDir);
.
etc...
.
}
catch (Exception ex)
{
}
}
I'm calling it to from a web application (servlet) running in tomcat
in
conjunction with struts and velocity. If I use the Lucene 1.2 binary
release, it all works fine and I get the search results ok. However,
when
I replace the 1.2 jar file with the 1.3-rc2 jat file, (leaving all
of my
code exactly the same) it stops working, and I get a path not found
exception being thrown.
I've narrowed it down to the IndexReader.open(final Directory
directory)
method. Even if I pass a valid Directory object into this (created by
FSDirectory), it just seems to throw the exception, (even though I
know
the directory object is not null etc). The bizarre thing is that this
problem only seems to occur when I run it from the web application.
If I
invoke the same code from the command line, it works ok, (even though
I'm
using the same string for the index dir).
Anyone got any ideas? (I want to use 1.3 because I want to exploit
some of
the newer features). Does running from within a web application do
something strange with the paths, even though the strings I'm using
are
fully qualified?
Thanks for your help,
Iain Young

Re: Help with Searching indexes from a web app (Lucene 1.3 rc2)
Please, always include the full exception when reporting a problem.
As for your problem, I would guess that it has to do with where Lucene
puts its temp files. I think that something changed between 1.2 and 1.3
and on Unix it started using /tmp instead of the index directory for the
tmp files. So somehow from your webapp you don't have permissions to
write /tmp. Are you running a security manager, by any chance?

Dror

RE: Help with Searching indexes from a web app (Lucene 1.3 rc2)
Note, that I've just tried the example webapp supplied with Lucene, and I
appear to be having exactly the same problem with that. The 1.2 version
works ok, but the 1.3 version is displaying a path not found error.
Are there any known incompatibilities with certain versions of Tomcat (I'm
currently using version 4.0.3)
Thanks,
Iain
