RE: Jasper2: serious problem with tag declarations
The scope of scripting variables from tags is specified in the Tag. From the 1.1 spec:
The defined values for scope are:
· NESTED, if the scripting variable is available between the start tag and the end tag
of the
action that defines it.
· AT_BEGIN, if the scripting variable is available from the start tag of the action
that
defines it until the end of the page.
· AT_END, if the scripting variable is available after the end tag of the action that
defines
it until the end of the page.
The scope value for a variable implies what methods may affect its value...
So while declaring two id's the same is an error IMO, the specific tag logic:iterate
should probably be NESTED rather than AT_BEGIN (which is what's happening).
Checking the struts code (org.apache.struts.taglib.logic.IterateTei), it is indeed
declared as NESTED. Looks like a Jasper 2 bug then. Time for a few extra {}'s?

I'll try to extract a test case.
There is nothing special about 'id' - just 2 consecutive struts
logic:iterate id='foo' . This generates a variable 'foo'
( via TLD/TagInfo/etc ), and the problem is that the variable foo is
declared twice ( there are 2 'Object foo;' in the same scope ).
I'm not very familiar with struts ( but you may find some

stupid in the page, this issue may be serious.

I see some errors, not sure yet if it's an error in the taglibs or
jasper but seems serious. ( the taglibs are from struts ).
There are few logic:iterate id=foo tags in the page, using the
same id, and the generated code has:
Object foo;
Object foo;
...
That obviously doesn't compile.
I don't know too much about struts, but I suppose it is valid to use
the same value in 2 tag attributes, couldn't find any reference on
the contrary in the spec.
It workes fine with older jasper.

RE: MinTC, terrible rudeness, persistence
I have to admit not having read the MinTC source, however, I thought the tomcat community uses/develops multiple implementations of many interfaces. Most of the http/socket/auth?/config (xml file/ajp-webapp/admin) code is effectively multiple implementations of the same interfaces. Isn't the whole design of catalina intended to allow different implementations of practically every concrete class? I get the impresssion MinTC is developing different config/bootstrap/resource-location implementations, but that much of the code is shared as is? If MinTC was replacing the core processing of Tomcat 3.3 i'd be more inclined to take your point, as the request chain is much more dedicated and part of the whole, whereas catalina is just a bunch of nested containers isn't it? -Original Message- From: Remy Maucherat [mailto:[EMAIL PROTECTED]] Sent: 19 April 2002 13:24 To: Tomcat Developers List Subject: Re: MinTC, terrible rudeness, persistence Another (non-committer) +1 for keeping MinTC on tomcat-dev.

RE: tag pooling question
As a quick note, I did some Jasper profiling on a previous project (it was Jasper from 3.1, running inside weblogic 5.1). The single biggest runtime cost, was all the calls to Introspector.getBeanInfo(). I created a cache of these using a similar technique to FastHashMap in commons collections (in Fast mode), and lowered the runtime costs significantly (for the calls i looked at say, 60%! (I think)). It was a trivial fix for the large benefit. Introspector does all the work every time, and instantiates a new BeanInfo for each call. Also, the cache only needs to expand to contain all the tag classes - a fairly small, finite set. I didn't submit it before, as it was at the time of Jasper4 / tag pooling being touted and thought the heavy runtime reflection stuff would be obsolete soon... -Original Message- From: costinm Sent: 27 March 2002 22:54 To: tomcat-dev; Kin-Man.Chung Cc: costinm Subject: Re: tag pooling question On Wed, 27 Mar 2002, Kin-Man Chung wrote: Pulling codes out of iteration tag bodies is very high on my list of optimizations that I wnat to do.

Same for a simple iteration tag, compared with a scriptlet If you solve those simple problems, and get the tag version in a reasonable limit, I think we'll all be very happy ( 30% slower would be acceptable for me, even 1/2 the speed of the equivalent scriptlet ).

Hi,
Two things.
1) Your servlet implements SingleThreadModel -- which means Tomcat *may*
create multiple instances of your class -- how do other servlets get hold
of the instance? The public method is not static - did you mean it to be?
2) In order to flush the (instance) variables to other threads (according
to the Java memory model) your should synchronize all access to them.

Subject: Hello !
I am a new user in this list, and i'm French so please forgive my
mistakes !
I am developing a project with Tomcat and servlets technology, and i
have the following problem i would like to submit to you:
I have a basic servlet S1 who includes several methods useful for all
the other servlets.
The appli works fine... but suddenly, i get a loss of context that i
can't explain.
One of the servlets who calls a S1's method sees all the global
variables have a NULL value, while a few moments before these values
were correctly defined.
These values are config parameters read from the web.xml file of the
appli. They are initialized in the init() method of the S1 servlet.
So i wonder what's going on...
Is there any config or servlet memory timeout that raises ? or what ?...
It is a serious problem because all the application becomes
unpredictably unusable, until i restart Tomcat.
Here is a bit of my S1 servlet code :
/**
public class S1 extends HttpServlet implements SingleThreadModel {
private static String P1;
...
//
// methode d'initialisation: recuperation des parametres de conf
public void init(ServletConfig sc) throws ServletException {
if (sc == null) {
System.out.println(ServletConfig = null);
System.exit(1);
}
super.init(sc);
try {
P1 = sc.getInitParameter(P1);
...
if (P1 == null) {
System.out.println(Paramètres de configuration de l'application
incorrectement renseignés.);
System.exit(1);
}
else System.out.println(Contexte Base de signalements chargé.);
}
catch (Exception e) {
e.printStackTrace();
System.out.println(Lecture des paramètres de configuration de
l'application impossible.);
System.exit(1);
}
}
// method called by other servlets
public String m1(ServletOutputStream out) {
// uses init parameters such as P1 and returns a result
...
}
/**
thanks for any help

Jasper performance query (circa 3.1 code)
I'm using Jasper in Weblogic from tomcat 3.1 (ish, we've patched a couple of things too). While profiling some of my JSP's, I see the JspRuntimeLibrary.introspectHelper consuming between 40-70% of the time, and a large %age of the object creation. Drilling down, most of the time is the line (which is still in Jasper34) java.beans.BeanInfo info = java.beans.Introspector.getBeanInfo(bean.getClass()); Which in turn is slow due to the construction of the BeanInfo (concrete class: GenericBeanInfo) So my question is: why isn't this cached? Or rather, if I were to cache this object, what are my problems? Those I see so far are: 1) If it's cached, where is the cache held? (a) If within JspRuntimeLibrary, I must synchronize the Map -- may cause a bottleneck between threads, since this is called hundreds of times per JSP. (b)If not here, then perhaps on the thread -- we're using our own subclass at this point (most of the time) so I could store it as a thread local there, or change the generation to pass in a storage object / cache. 2) Will this prevent class reloading from GC'ing the old classes, unless the map is released? For our app, reloading is only a dev feature so not too worried about this. 3) Am I reading my profiler wrong and this shouldn't be a bottleneck? I don't think we can wait long enough for the Jasper refactoring to happen, so am looking for smallish changes currently. Ken.

Re: httprequest fired twice
IE firing off multiple requests is quite common - esp when it's trying to download something - we had it with PDF's. Typically it'll use different headers each time too if only it would pay attention to the headers provided instead..

Re: Jasper performance
We use Jasper (from a 3.1 build!) in another container. How big is the change if we wanted to move to the 3.3 version to get the tag pooling. I'm about to start performance testing our app, and currently the pages are taking ages to render (we build up to 1Meg of html.. :o), so we'll be looking at this area soon. In terms of a quick hit, anybody got opinions / experience of changing the generation to use an unsynchronized version of StringBuffer, I think this may show up as a possible easy enhancement. Ken. [EMAIL PROTECTED] on 15/05/2001 15:22:17 Please respond to [EMAIL PROTECTED] To: [EMAIL PROTECTED] cc:(bcc: Ken X Horn) Subject: Re: Jasper performance Jasper performance has already been identified as an area needing improvement. Discussions and work on this has already started in the main tomcat branch in CVS jakarta-tomcat/proposals/jasper34, but this may be moving to the CVS repository jakarta-tomcat-jasper. This work just started recently, I don't know when it will be ready. It will take few months - it's not that easy. We already added tag pooling in tomcat3.3, and that have a significant effect on performance if you are using tags - but that's just the beginning. The first step is to reorganize the code. Then we'll try to make the code generator more customizable ( probably by using XSLT for some of the operations ). The real performance enhancement will come when we start tunning the generated code - there are many ideas around, but we need the refactoring first. BTW, jasper will share most of the code for the 1.1 and 1.2 APIs, so all enhancements will be available in both 3.x and 4.x ( and other containers as well ). If you have ideas, code or opinions - please get involved, we need you :-) Costin Rickard Öberg wrote: Hi! We are using Tomcat/JBoss and are pleased with the actual functionality. What is killing us right now is the performance of the code generated by Jasper, especially when using taglibs in complex ways. The generated code is way too unoptimized. So, if this has not been asked before (in which case a RTFA is ok, although I've looked already), my question is: When will Jasper be rewritten? Are there any such projects underway now? Have there been any discussions about this yet? Am I the only one seeing this problem, or are more people concernced about it?
