RE: Illegal target of jump or branch w/Tomcat

2002-11-21 Thread Emmanuel Bridonneau

Good stuff to all of you regarding overcoming the 64kb limitation in a single method.
JBoss 3.0.4 uses Tomcat 4.1.12, though we may want to try the version with integrated 
Jetty (JBossWeb) first.
Thanks a lot.

Recent Tomcat 4.1.x releases include a completely rewritten "Jasper 2" JSP
Page Compiler.  Besides running custom tags a ***lot*** faster (very
visible on a page with lots of Struts tags), this compiler tries to work
around the 64k limit on method size by factoring out some nested chunks of
code into separate methods, thus arbitrarily increasing the maximum size
of a page.  This works, however, only if you have zero scriptlets -- but
that should not be a problem for well-designed JSP pages.

You'd have to check with the JBoss folks when they plan to integrate with
a 4.1 release of Tomcat.

One other thing I forgot to mention - you can also use  to
break your pages into smaller chunks for the JSP compiler, and put them
back together at run time.

The latest versions of Tomcat use Jasper2 to compile JSP pages. Jasper2
apparently breaks up the generated code to avoid hitting the limit you are
encountering. If you can move to a later Tomcat, that would probably be
the best way to go.

If you can't switch container, one other point to bear in mind is that
non-body tags generate less code than body tags. If you have your own tag
library, you might consider changing some of the body tags to non-body
tags. If you're really desperate, you could created modified versions of
some of the Struts tags so that they are non-body tags, or create
composite tags. (This is something I ended up having to do some time ago
because some of my pages were blowing the limit on a daily basis!)

RE: Illegal target of jump or branch w/Tomcat

2002-11-20 Thread James Childers

We ran across this exact same problem recently, and it has to do with the way 
that the servlet container does the JSP --> Java translation. You are likely to
encounter this problem if the container puts everything  -- scriptlets, custom 
tags, etc. -- into a single monolithic _jspService method, which is what most 
containers do. I asked the Jikes-dev list about this, and this was the response:

"It is a fundamental flaw in the .class file format.  You currently can't 
have a method with more than 64K bytecodes.  (Well, technically you can, 
but it cannot have any exception handlers after the 64K limit, and it 
relies on the mercy of the VM to not crash).  See JVMS 4.10.  Sun is 
considering extending the .class file format in JDK 1.5, to allow up to 
4GB bytecodes in a method, at the expense of requiring such .class files 
to be run on a 1.5 compatible VM, but that doesn't help you now."

We saw this problem when we started using 400+ custom tags in a single page. The 
newer versions of Tomcat do not suffer from this problem because they are smart 
enough to put the custom tag logic into separate private methods within the 
generated .java file. (At least when I tested it on Tomcat 4.1.12 the problem
disappeared for me. YMMV.)

2002-11-20 Thread edgar

I believe the simplest way of dealing with this is just to use nested
classes.  Dr. Kabutz has an interesting discussion of Java limitations
(attached).

I.E. if you have a class

class A {
m1
m2
...
mn
}

Use instead

class A1 {
m1
m2
...
m (n/2)
}

class A2 extends A1 {
m (n/2+1)
...
mn
}

Let me know if this solves your problem.

As I mentioned in an earlier post on this topic, using <%@include%> does 
not help, since it's a compile time include (similar to #include in C++). 
Using  can help, though.

Re: HELP - "Illegal target of jump or branch"

2001-03-20 Thread Martin Cooper

I am, unfortunately, intimately familiar with this problem.

The problem is that there is a limit on the size of a compiled method in a 
Java class file, and that limit is what we're running up against. Recall 
that a JSP page is compiled into a servlet, and into essentially only one 
method in that servlet. Hence, if your page contains many, many tags, that 
method becomes too big, and up comes the exception that you're seeing.

There are a couple of (partial) solutions.

1) Break your giant page up into multiple smaller pages and bring them 
together at run time using . Note that <%@include> won't work, 
because that's a compile-time include, which will get you straight back to 
the original problem.

2) Look for places to save on tags. For example, the  tag was 
recently extended to allow the specification of the text to display, so 
that you can replace this:

with this:

If you have a lot of cases of this pattern, it can help quite a bit. In 
addition to the  tag, some other Struts tags allow the same 
shortcut to including the text. Also, you might consider replacing 
 sequences with  if you can build an appropriate 
collection up front.

Unfortunately, we can't use solution (1), because our giant page is almost 
entirely one . (Please don't ask... :-} ) Many of the  
tags won't work if they are on a separate page from the  tag 
itself. That means I've spent quite some time on option (2).

We have several of our own tags, too, so that was the next place for me to 
look. I discovered that changing some frequently used tags from extending 
BodyTagSupport to extending TagSupport, and marking them with 
empty in the .tld file, made a significant 
reduction in generated code size. Of course, this is not always feasible, 
but it helped us quite a bit.

One other trick is to create custom tags for frequently used groups of 
related elements. For example, I created a simple DatePickerTag which is a 
Struts-like tag that combines three drop-down boxes for month, day and 
year, with the localized strings obtained from the JVM, and the current 
values pulled from a bean.

That's about all I can think of that I've tried so far. All our pages are 
now within the limit, but one is very close to breaking it. I really want 
to put a "do not touch" notice on that file!

Hope this helps.

Marc,

This may be related to the size of you resulting jspservice method.

If that is the case you need to break it up into multiple includes - as
recommended to someone else earlier today.

I think this is due to hitting the 64kb limit in a class file (a 16bit
offset for the byte code in a method). I had similar problems using Jasper.
I managed to refactor the page so that the number of actual tags was
reduced (put a loop in it, so the tags were called multiple times). Using
scriptlets (!) can also help significantly... or if you can afford the
flush, use jsp:include  (roll on JSP 1.2).

Interesting. A colleague of mine started seeing exactly the same problem
today, but with Resin instead of WebLogic. I had never seen it before.

It seems, on the face of it, to have something to do with the complexity of
the page. The page we were having problems with has a boatload of custom
tags on it (some Struts, others our own). When we commented out a sizeable
number of those tags, it started working again. Which particular chunk of
tags we removed did not make a difference, which is what led me to believe
it was related to page complexity. However, that's as far as I've got.

I'd be very interested in hearing the "real" reason behind this error, as
well as what we might be able to do about it.

Interesting. A colleague of mine started seeing exactly the same problem
today, but with Resin instead of WebLogic. I had never seen it before.

It seems, on the face of it, to have something to do with the complexity of
the page. The page we were having problems with has a boatload of custom
tags on it (some Struts, others our own). When we commented out a sizeable
number of those tags, it started working again. Which particular chunk of
tags we removed did not make a difference, which is what led me to believe
it was related to page complexity. However, that's as far as I've got.

I'd be very interested in hearing the "real" reason behind this error, as
well as what we might be able to do about it.

Re: "Illegal target of jump or branch" Error

I think this is due to hitting the 64kb limit in a class file (a 16bit
offset for the byte code in a method). I had similar problems using Jasper.
I managed to refactor the page so that the number of actual tags was
reduced (put a loop in it, so the tags were called multiple times). Using
scriptlets (!) can also help significantly... or if you can afford the
flush, use jsp:include  (roll on JSP 1.2).

The same call in Tomcat is successful.  Does anyone know what causes this
error?
