[NEWBIE] Creating context-relative URLs with Tomcat + Struts
Hi all, this is my first post, so I hope not to bore you too much with my
questions:
Ok, let's say that I would like to translate system's specific URLs (i.e.
D:\Tomcat\webapps\foo\foo\bar.jsp and so on...) into web-context specific
URLs (i.e. http://myServer/foo/foo/bar.jsp). Well, if I immagine to replace
D:\Tomcat\webapps with http://myServer things seem quite easy. My first
question is: is this the right way? As I am very new to Lucene, is there a
possibility to instruct the IndexWriter to replace system path with web path
(specified as argument) during index creation?
Secondly, this is for Struts users, a jsp page not necessarily can be
executed without passing from a Struts Action (i.e. an Action prepared some
data to display, and if we try to access the jsp directly we could have some
bad 5 minutes), so my question is: did anyone encountered this kind of
questions? Did you find any solution? For this second subject, I could think
to a sort of mapping file between JSPs and relevant actions, so that we can
assume that if the user clicks on a JSP link, instead the relevant action
for that JSP will be executed and then the JSP displayed. The mainteinance
for this solution seems CRAP.
Hope someone of you will help,
Marco

Jeff, that exactly what I'm realizing.
First of all I have been able to read the configuration file (by keeping an
instance of ModuleConfig at startup) and therefore to realize a mapping
between (action -> JSP). This has been only possible because even for simple
forwards I used the Struts ForwardAction. I also found the way to isolate:
protocol + server | web-app-context | action/jsp | Servlet mapping (.do /
/action/).
In the meantime, I created a stateless session bean which has a method
which, given an environment variable as a String, returns the path to that
environment variable; therefore it will be quite simple to replace, let's
say, CATALINA_HOME with the information I isolated as mentioned above.
I'm going to create an entity bean (therefore a db table) with the isolated
information (i.e. protocol, context, and so on);
when user will run a search, and possibly Lucene will return to me the list
of system-relative JSPs, I'll substitute the system-path with the web-path,
by concatenating all the web-relative information stored in the database,
and instead of presenting to the user the list of links to JSPs, I'll show
him the list of links to actions.
There is still a major problem to solve; realize somehow the mapping between
actual content-matching JSPs and JSPs which define only Tiles 'define'
statements. The reason is that the JSPs mapped vs an action in the struts
configuration file are basically empty.
I'll have to work around it.

Why don't you set the path field to be relative to whatever the base
directory is that the administrator puts in? So, you write the path
field yourself, and just put in the relative link, like /index.jsp,
/welcome.jsp, or whatever? You can just use the relative link directly
in your web application.
The book chapter covers pulling content out of a database through a data
access layer, so it's a little different than pulling files out of a
file system, but most of the basics are the same.
If the actual content is hidden behind wrapper JSP pages, Struts
Actions, parameters, or whatever, the display code that writes the links
out in the JSP page can reference a mapping like you said. The hard
part would be writing the mapping code, calling it should be easy.
Hope this helps,
Jeff

Hi Jeff, DAMN!, two of the books I haven't got :) I bought Jakarta Struts
from O'reilly and another one on JSP/Servlets/Web programming.
I already wrote the user interfaces and the classes (I wrote a stateless EJB
which performs both the indexing and the researching of the result) to run
the search.
My problem is another: as you'll certainly know, as I'm running on Windows,
my Tomcat home path is something similar to:
D:\Tomcat\

Hi,
I don't know of any books on just Lucene, but I wrote a chapter on Lucene in
Professional Struts Applications. Since you're apparently using Struts, you
might find it useful. Another book that has a chapter on Lucene is
Professional JSP.
One thing you should know about Lucene - it's not a ready-to-run search
engine. You can't just drop it into a web application and let it go, you
have to write the code to add the content to Lucene yourself, and write the
web pages to search the Lucene index and display the results.
Thanks,
Jeff

Sorry Scott, I was under the flies of enthusiasm :) I'm trying to realize a
simple web-site search functionality and I would like to use Lucene as
index-search engine.
BTW, does it exist any book on Lucene?

Marco,
You may want to explain what you are trying to do before you start
describing your problems.
For example, I have no idea how / why you would use Lucene to do either
of the things you are talking about below.
Cheers,
Scott
