Re: [programmazione] Struts vs JSF (poll?)
Hi, keep in mind that JSF is a very powerful framework, but it has also some limits. The biggest one is that to work correctly javascript must be enabled on the client browser. So, as first, take care this is a very strict specific. Where it is possible i like using JSF (sun), otherwise I go with struts. Using NetBeans and the so called visual JSF (woodstock project) is not mandatory to develop a JSF app. (That is : u can use eclipse :-)) In any case, I suggest to invest in know how about the framework u decide to deal with. Also if some tools can give the impression everything is simple to do, a deep knowledge of the choosen framework is always necessary.

Hi everyone, This maybe out of scope for this list but I wanted to know more about Struts vs JSF other this old article [1]. Which are are deployed mostly on your TC server(s)/cluster(s)? If any Java developers are on this list, which platform API do you prefer for quick development (to meet deadline), performance, security management (user authentication and level restriction) etc... since both are based on MVC despite their different implementations(?). Since there isn't a JSR for Struts, has Struts been around before JCP is formed? And why is there not a JSR for Struts now (just curious)? As for JSF, which implementation is used by/for your app(s)? Sun/NetBeans? Apache's MyFaces? or Others (please list)? I'm somewhat disappointed Netbeans support for JSF and Struts in that Netbeans bundled libs support used older Apache Commons lib version (even for the current v6.1), although this could be updated but I don't know whether it will break the integration of Netbeans' VWP. Even the tutorial/trails on NetBeans site regarding Struts (although this can be compensated at Struts' web site) is very limited perhaps because of the (biased?) Struts weak integration to favor or push more on JSF/Visual JSF? I need to evaluate my options of API and IDE before I dedicate several projects since the performance of Netbeans is getting worse by every release comparing to Eclipse.

Re: [programmazione] Servlet Caching
Hi, [EMAIL PROTECTED] is a static include, that is at compile time the compiled code of the INCLUDED jsp is simply copied. But if you change a included jsp/servlet after the INCLUDING page has been compiled, well, nothing happens in the INCLUDING. You have to touch (modify something) the including jsp to make it recompiled with the included modified code. An other option is to dinamically include the page using: jsp:include but it is really a different behaviour. Every time the including is called it dinamically recall the included one.

Re: [programmazione] Re: Tomcat failover
Answering your question: assuming you have a apache web server proxing the first tomcat with mod_jk (so mod_jk help), you shuold have a thread in your second tomcat which interrogate a servlet in the first tomcat and if the answer fails this thread should reconfigure the worker (the mod_jk) so that apache web server redirect the requests to the second tomcat. Honestly it doesn't seems to me to be a solid solution (what about the second tomcat crashes too? what about the sessions in the first tomcat?). A better solution could be clustering: http://tomcat.apache.org/tomcat-6.0-doc/cluster-howto.html Also give a try to terracotta to keep save your sessions. In this case you could also have a typical load balanced cluster with net balancer.

Re: [programmazione] Embedding custom metadata in a jsp page; access generated Class via reflection?
I would use the Model-View-Control pattern.
First it must be defined a Controller, which is simply Servlet mapped to
catch all the request.
This servlet can read the XML and append your metadata to the request and
forward it to the correct jsp (which will handle your metadata i suppose)

Subject: [programmazione] Embedding custom metadata in a jsp page; access
generated Class via reflection?
Hi,
I need to associate some custom metadata with JSP pages, and access it
*before* the page is rendered.
The current implementation uses an xml with the same name as the jsp, eg
foo.jsp
foo.xml
so that when I'm about to forward to foo.jsp I first look for a
foo.xml file and if present parse it to extract the metadata.
I'd really like to embed that metadata within the jsp page itself - but
need access to that info *before* the jsp page executes.
(a)
Is it possible to obtain the name of the Class that is generated for a
jsp, so that I could do introspection on it?
It would then be possible to embed something like this into the page:
%!
private static MyMetaData metaData = new MetaData();
public static MyMetaData getMetaData() { return metaData; }
%
and look for/invoke the getMetaData method *before* forwarding to the
page.
Of course, this also requires that the servlet-class for the jsp has
actually been generated. Is there a way to guarantee this is done for any
particular jsp before actually doing a forward?
Note that requiring pre-compilation of all jsps is not an option. This
metadata stuff is needed for an open-source framework, and it is not
reasonable to tell every possible user of this framework to precompile
their jsps.
(b)
If the above is possible, is there a way to generate those static members
from a custom JSP tag? It would be nicer to be able to do:
myns:declareMetaData /
and have that define the static members listed above.
Or perhaps someone can suggest an alternate approach to embedding metadata
that can be accessed before the page renders?
Thanks,
Simon

Re: Committing sendRedirect()
Maybe a solution could be to use AJAX client side to make the multiple

The client make the first request, when the server answers the client make
the following request and so on.
So the desired effect should be reached.

Subject: [programmazione] Committing sendRedirect()
Hi everybody,
I have a problem with redirects in Tomcat 5.5.25. I am doing a Lucene
search and would like to send a redirect after finding the top 25 hits,
commit this response, and then continue processing the remaining hits.
The relevant parts of the doPost() code are as below:
final int PARTIAL_HITS = 25;
for (int i = 0; i hits.length(); i++) {
Document doc = hits.doc(i);
String citation = doc.get(citation);
/** Insert into table */
try {
insertId.setInt(1, java.lang.Integer.parseInt(citation));
insertId.executeUpdate();
}
catch (SQLException e) {
out.sendError(500, Bad SQL insert: + e);
}
catch (Exception e) {}
if (i == PARTIAL_HITS) {
// Intermittant redirect
out.sendRedirect(resultUrl);
}
}
insertId.close();
if (!out.isCommitted()) {
// Final redirect
out.sendRedirect(resultUrl);
}
My problem is that the intermittant redirect is not committed until the
function returns, which will take quite some time for some queries. I
have tried HttpServletResponse.flushBuffer() and other possible
variations. Any pointers would be most appreciated.
