Re: executing jsp independently

[Mark Roth]

Nishant,
In JSP 2.0, we laid some of the groundwork for running JSPs 
independently of a container.  Here are some pointers:

1. The JspContext API does not rely on any Servlet APIs.  JspContext
   is the new superclass for PageContext.
2. JspFragment does not rely on any Servlet APIs
3. Tag Files do not rely on having a request / response and do
   not need any Servlet APIs.
I'm sure it's possible to emulate a full Servlet environment, but I 
think the right way to do this is to start the execution from a tag file 
instead of a JSP page.  Tag files were designed to be able to run 
without a container if need be.  You'd still need to emulate the 
request/session/application scopes, but that's about it.  Tag files have 
the same capabilities as JSP pages, but they don't need a ServletRequest 
/ ServletResponse.

This is work the JSP is eventually interested in formalizing in the 
spec, so we'd be very interested in your feedback.  Please report back 
on our JSP spec mailing list with your progress and findings:

hi,
I am generating a html report using JSP. we also exporting this report
to pdf. since the fop conversion takes quite a long time we have to do
this export asynchronously. for this we have to use velocity. is there
any way i can use JSP for this purpose.
Had it been sync, we could have used JSP to create the fo which could
have been transformed using a filter. but in the async mode tomcat
reuses the same request and response objects for some other request, so
can't use this trick.
Though JSP and servlets are meant for synchronous request handling, I
THINK executing JSP independently should be possible if we are able to
pass it some dummy request and response objects.
I am ready to tinker with tomcat code locally to get this working. Any
advice or pointers to relevant piece of code?? I think this is dev
question, if not I am sorry for posting on the wrong list.
thanks,

All excellent questions.  I think the answer at the moment is that it's 
somewhat too early to tell.  Stay tuned for more information as it 
becomes available.

I just wanted to put it on the radar of those who were interested in

[Fwd: PHP/JSR223]

[Mark Roth]

For those that are interested, here's a summary of JSR-223, straight 
from the spec lead.

Hi Mark

Here's a little essay on the relationship between the JSR and PHP.  Feel free to 
forward it.

JSR 223 defines an API used to embed scripting engines in Java applications.  As a 
special case, it defines a class of Servlets that  host scripting engines. The engines 
generate web content by executing scripts.

One of the implementations uses the native open source PHP code and the corresponding 
Servlet executes that code.  There is a PHP SAPI whose callback functions are 
implemented using JNI calls into the Servlet and Servlet Container.  The PHP scripts 
can also instantiate Java Objects using the Web Application's ClassLoader and invoke 
the public methods of the objects.  In cases where it makes sense, native PHP syntax 
can be used to do enumerations/iterations and access collections at indexes.

The spec can also be implemented (more easily, in fact) using any of the many 
Java-based scripting engines.. Rhino, Jython, BeanShell, Groovy, etc.

The spec won't specify how  particular scripting languages call Java.  We assume that 
all of them can do it in their own fashion.  With all of the Java-based scripting 
engines, this is a built-in feature.  To do an implementation with PHP, we did it 
ourselves. 

The JSR also does not deal specifically with native applications.  It just so happens 
that one of the implementations uses the native PHP sources to implement the Java API 
that the JSR does deal with.

The Java support in PHP4 is experimental and labeled as such.  It contains a lot of 
good ideas, some of which we used,  but as it stands, it probably isn't usable.

Re: PHP from Tomcat , some news from JFC :)

[Mark Roth]

From what I hear, the current PHPServlet is okay for simple things, but 
the integration you're looking for is not quite there yet.

There's some work going on to let Java and scripting languages act more 
friendly with each other.  For those who are interested, check out 
JSR-223, Scripting Pages in Java Web Applications.

http://jcp.org/en/jsr/detail?id=223

This JSR focuses on tight integration between PHP (or other scripting 
languages) and Java webapps.  Zend is an active participant on the 
expert group and is interested in such integration.

I believe they're building their RI on top of Tomcat.

Cool stuff!

Did you try it ? I'm curious, could you run a quick helo world benchmark

The big question is the level of integration - i.e. if you can call java
objects from php or use some of the nice PHP features from java.

Re: cvs commit: jakarta-tomcat-jasper/jasper2/src/share/org/apache/jasper/compiler Generator.java

[Mark Roth]

Okay, I took a look at the patch and the bug report and I think I know 
what's going on now.  Please let me know if I do not understand the 
scenario correctly.

It seems there are some JSP 1.2 pages that misuse  by doing 
one of the following:

  1. The class attribute is used for a Java type that cannot
 be instantiated as a JavaBean.
  2. Type or class specifies a type that cannot be found.
There are some cases where pages can get away with (1) if the container 
decides to flag this as a runtime error.  These pages are invalid but 
the container never calls them on it because the objects already exist 
in some scope.  This is probably less likely with (2), but still 
possible (e.g. if the  never gets executed at all).

It would be nice to get a translation error in this case so that you 
realize your page is invalid.  However, the JSP 1.2 specification (on 
which Tomcat 4.x is based) does not allow for a translation error - it 
requires that a runtime exception must be thrown.

In JSP 2.0 (on which Tomcat 5.x is based), a number of JSP container 
vendors complained about this and wanted the freedom to throw a 
translation error in this case.  Doing so is better for the page author 
(since they know up front their page is invalid) and better for the 
container (since doing a 'new' is MUCH more efficient than doing a call 
to Beans.instantiate()).  So, we added a provision to allow containers 
to optionally produce a translation error on these invalid pages.

One unfortunate side-effect is that some pages that used to compile in 
Tomcat 4 will no longer compile in Tomcat 5.  But it's important to 
realize that these pages are invalid in both specs.  It's just that 
Tomcat 4 was not allowed to cause an error at translation time.  It had 
to wait until runtime to do so.

So where does this leave us with respect to this patch?  Tomcat 5 is 
free to exhibit either behavior.  It can throw a translation error or a 
runtime error for these invalid pages.  In my opinion, it is much better 
for both the page author and the container if we produce a 
translation-time error.  The page author knows their page is invalid 
right away (without having to exercise the code path), and the container 
can gain the performance benefits associated with doing a 'new' call 
directly (instead of Beans.instantiate()).

So it's your call, but if I had a vote I'd say stick with Kin-Man's patch.

Hope this helps.

Ok.

Also agreed that this breaks backward compatibility; but it not really 
too
bad.  I think a lot of users would rather have the error at compilation
time than at runtime.  What can you do with an instantiation error at
runtime?


Nothing, but some don't care: they never intended their page to be 
called without the right attribute in the right scope, so the case where 
their "JavaBean" is instantiated never happens.

If we are really concern about BC, then we can add another compilation
option to revert to old behavior.  I really don't like another switch, 
but
if it'll make people happy...


No new switch, please ;) So we have to decide one or the other.
So do you want me to revert the patch ?

I don't like producing an error here - if prior versions of Tomcat

to log a friendly warning to the user since the application is not

Re: Important information about jakarta-servletapi-*

[Mark Roth]

Hi Mark,

Mark Thomas wrote:
Mark,

One final question. The javadoc bugs I was looking at were of the following 
types:
 - @returns used rather than @return
 - @seealso used rather than @see
 - etc
Yuck.  :)  It's unfortunate we didn't catch those earlier.  I'm 
definitely interested in a list of any such bugs in the JSP APIs and I'm 
sure Yutaka is too, for Servlet.  Please send a summary of any such 
errors to the spec aliases and we'll be sure to catch them in the next 
revision of the specs.

Is it permitted to make changes to fix these? There were no changes to the 
actual text of the javadoc.
Unfortunately, the answer is no, even though it seems rather silly.  The 
reason is that the specifications themselves have an auto-generated copy 
of the javadocs in PDF format, and the assertion list for the TCK is 
generated, in part, based on the javadoc tags.  Converting an incorrect 
@returns to a correct @return would make both the spec PDF and assertion 
list get out of sync with the API workspace.  There are other 
side-effects as well.

Thanks in advance for the summary to the specification aliases!

Does this mean that any bug submitted with a criticism (or patch)

[EMAIL PROTECTED] ? (I know there is at least one bug in 
this category)
If the bug fix results in a change to the externally-visible portions of 
an API class (javax.*), the change MUST go through the JCP.  The best 
way to get such an issue considered is through the mail aliases I 
mentioned in the previous email.

Fixing bugs in the implementation of such classes resulting in NO change 
to the external interface (e.g. signature of public/protected methods or 
javadocs) is okay.

Additions, removals and changes to other portions of this workspace, 
such as the sample applications, are entirely okay.

I'll leave it up to the Tomcat team to decide how to handle the 
paperwork (e.g. whether to mark bugs as WONTFIX or not).  Your 
suggestion sounds reasonable to me.

It's probably a good idea to outline these rules in a README.txt file in 
the workspace as well.

Hope this helps.

Important information about jakarta-servletapi-*

[Mark Roth]

Hi everyone,

I've seen a few requests to fix items in the jakarta-servletapi-* 
workspaces and wanted to clear up any confusion there might be.

Changes to examples in these workspaces are fine.

However, ANY changes to the core APIs (including even simple javadocs 
changes) CANNOT be done outside of the JCP process.  This applies to 
both Servlet and JSP APIs.

To make any changes to these APIs, you must propose the change through 
the spec aliases, which appear on the front covers of the corresponding 
specifications:

Servlet: [EMAIL PROTECTED]
JSP: [EMAIL PROTECTED]
Your change request will be considered by the specification leads and 
potentially debated by the expert group.  Changes to the APIs can only 
be done in a maintenance release of the specification, or in the next 
revision of the specification.  The Servlet 2.4 and JSP 2.0 
specifications have both been finalized for this release of Tomcat and 
are very unlikely to change in any substantial way until the next release.

Please understand that Tomcat is only one of many containers that are 
implementing the Servlet and JSP specifications, and the APIs must match 
identically on all containers.

Please don't hesitate to contact me if you have any questions on this 
matter.

Thank you for your cooperation.

Re: JSP implicit writer (out) vs. response.getWriter()

[Mark Roth]

Hi Karl,

The result is not unexpected.  See the JSP 2.0 specification, section 
JSP.1.7:

"...JSP page authors are prohibited from writing directly to either the 
PrintWriter or OutputStream associated with the ServletResponse."

The reason is that writes performed by the JSP page are normally 
buffered.  There is an implicit object 'out' that writes to the buffered 
JspWriter which will accomplish what you are looking for, in the right 
order.  So you should do this instead:

   
   
   Me first.
   <% out.println("Me second"); %>
   
   
Hope this helps.

After thinking about it a bit more, it seems the solution to the issue I raised yesterday is potentially simple: just use a "wrapped" response for the JSP response variable, which returns the JspWriter.  

create a new package class JspResponseWrapper: 

  class JspResponseWrapper extends HttpServletResponseWrapper {

private Writer out;

JspResponseWrapper(HttpServletResponse response, JspWriter out) {
  super(response);
  this.out = out;
}

public Writer getWriter() {
  return out;
}
...override other methods related to output stream/writer
  }
Then in PageContextImpl._initialize:

this.response = new JspResponseWriter(response, this.out);

Thoughts?

  Subject: JSP implicit writer (out) vs. response.getWriter()

  Hi all,

  I recently started working with Tomcat (4.1.29) and ran into an inconsistency between the implicit "out" variable in a JSP and response.getWriter().  Consider this JSP:

  
  
  Me first.
  <% response.getWriter().println("Me second"); %>
  
  
  I was surprised to discover that the out of this is:

  Me second.
  
  
  Me first.
  
  
  Looking at org.apache.jasper.runtime.PageContextImpl and JspWriterImpl, it appears that the 
"out" variable is set up
  with its own buffer, which explains why text sent straight to the response writer 
appears first (before the JSP writer buffer gets flushed).
  Am I missing something or is this the way it actually works?  If I have it straight, 
is this a bug?  I'm not sure about the
  JSP spec, but other app servers I've tried seem to accumulate text in a single buffer for both 
"out" and response.getWriter().
  Thanks,

  Karl Goldstein

[PATCH] jakarta-servletapi-5 JSP Examples improvements

[Mark Roth]

There were reports of the "View Source" option not working for the JSP 
examples in some versions of IE.  Apparently some configurations of IE 
will process the HTML tags in text files instead of rendering them as 
text.  I've made the following enhancements:

  * Created new ant task Txt2Html that converts text files to
escaped HTML in a 'pre' tag
  * Modified build.xml to build and import Txt2Html task
  * Modified build.xml to generate foo.jsp.html instead of foo.jsp.txt
using new Txt2Html task
  * Updated example HTML files to refer to foo.jsp.html instead of
foo.jsp.txt
  * Fixed some broken links and broken image links in some HTML files
  * Fixed plugin example to use relative path name to applet codebase
instead of absolute path

Re: JSP 2.0 Jasper in Jetty 5

[Mark Roth]

Greg,

Thanks - the new features in JSP 2.0 are directly as a result of 
feedback from the Java community.  We've received some excellent 
feedback, and the JSP expert group, composed of over 30 experts from 
various companies, has done a great job processing the most requested 
features and making this happen.

I hope we can continue this going forward, so remember to send all your 
JSP specification feedback, be it positive or negative, to 
[EMAIL PROTECTED]

Integration has been totally painless and the results appear to

Also the 2.0 features are very cool - I'll have to stop making
nasty remarks about JSPs!-)
So thanks again for jasper!  Good work guys!

Hi Luo,

You can create an index.jsp or index.html page in that directory and 
people will no longer be able to list the directory contents.

[PATCH] jakarta-servletapi-5: JSP 2.0 API updates

[Mark Roth]

Here are the latest round of JSP 2.0 API updates.  Some changes will 
need to be made to jakarta-commons-sandbox/el before applying this patch.

I also made a couple of changes to the JSP 2.0 examples in accordance 
with these changes.

jsr152/src/share/dtd/jsp_2_0.xsd:
jsr154/src/share/dtd/jsp_2_0.xsd:
- Expanded on description for taglibType complex type.
jsr152/src/share/javax/servlet/jsp/tagext/SimpleTagSupport.java:
- Change getJspBody() to be protected
- Change getJspContext() to be protected
- Change the jspBody field to be private
- Change the jspContext field to be private.
jsr152/src/share/javax/servlet/jsp/el/ExpressionEvaluator.java:
- Changed so that Strings of the form "abc${1+1}def${1+1}ghi" cannot
  be parsed or evaluated.  Only one expression can be parsed
  evaluated at a time, and no static text can appear.
jsr152/src/share/javax/servlet/jsp/JspWriter.java:
- Changed javadocs for print() methods to indicate that the
  resulting text is written to the writer, and not converted to
  the platform's default character encoding first, which would
  make no sense.
jsr152/src/share/javax/servlet/jsp/tagext/TagInfo.java
- getTagName() - Clarified that name is always returned (cannot
  be null)
jsr152/src/share/javax/servlet/jsp/tagext/Tag.java
- Accessibility fix.  Added img alt tag.
jsr152/src/share/javax/servlet/jsp/tagext/BodyTag.java
- Accessibility fix.  Added img alt tag.
jsr152/src/share/javax/servlet/jsp/tagext/IterationTag.java
- Accessibility fix.  Added img alt tag.
jsr152/src/share/javax/servlet/jsp/tagext/VariableInfo.java
- Accessibility fix.  Added img alt tag and table summary tag.
jsr152/src/share/javax/servlet/jsp/el/ExpressionEvaluator.java
- evaluate() - Removed defaultPrefix param and allow FunctionMapper
  to mutate after call.
- parseExpression() - Removed defaultPrefix param and allow
  FunctionMapper to mutate after call.

[PATCH] jakarta-servletapi-5 - EL examples

[Mark Roth]

Quick patch to improve JSP 2.0 EL examples:

  Commented out, since this is not yet implemented.
* Changed quoting from old-style ${'${'} 1 + 2 }
  to new-style \${ 1 + 2 }

Re: jsp:plugin tag MAYSCRIPT parameter not supported

[Mark Roth]

Hi Mark,

Thanks for your feedback.  For best results, please send feedback like 
this to [EMAIL PROTECTED]

This has been an RFE since JSP 1.1.  I'm asking the expert group about 
it now.  If all goes well, we can hopefully add it for JSP 2.0.

Because the MAYSCRIPT parameter is not supported in
the jsp:plugin tag I had to switch to directly
using the APPLET tags in my jsp.

I'm not sure who should be made aware of this
to fix the standard but it's possible the JSP
implementors here might want to add this before
it's official since an applet can't call in page
javascript without this parameter.

[PATCH] jakarta-servletapi-5

[Mark Roth]

Attached are a set of API patches leading up to PFD2 of the 
specification.  Look for a corresponding patch to jakarta-tomcat-jasper 
to bring it up to date with these APIs.

Also note the attached replacement for TagProtocol.gif.

jsr152/src/share/javax/servlet/jsp/tagext/doc-files/TagProtocol.gif
- Updated diagram to remove arrow from released state to all
  properties initialized state.
- Moved label [3] to another arrow.

jsr152/src/share/javax/servlet/jsp/tagext/Tag.java
- Removed state transition [3] from class javadocs.
- Added a new [3] label clarifying details about what may be called
  on tag reuse.

jsr152/src/share/javax/servlet/jsp/tagext/TagData.java
- Updated description for getAttribute() to clarify
  REQUEST_TIME_VALUE is returned for any dynamic attribute set
  via .

jsr152/src/share/javax/servlet/jsp/tagext/JspFragment.java
- "for example" --> "in other words"

jsr152/src/share/javax/servlet/jsp/tagext/VariableInfo.java
- Fixed incorrect class comment about variable scope.
- Removed old comment about JLS verbiage.
- Improved description of why 'boxed' types are necessary.

jsr152/src/share/javax/servlet/jsp/tagext/TagVariableInfo.java
- Fixed erroneous comment about only being available in JSP 2.0
  format

jsr152/src/share/javax/servlet/jsp/tagext/SimpleTag.java
- Clarified SimpleTag has the equivalent power of BodyTag but with a
  much simpler lifecycle.

jsr152/src/share/javax/servlet/jsp/tagext/IterationTag.java
- Clarified description for return value of SKIP_BODY from
  doAfterBody()

jsr152/src/share/javax/servlet/jsp/PageContext.java
- Fixed class description as some elements were moved to JspContext.

jsr152/src/share/javax/servlet/jsp/JspContext.java
- Fixed class description as some elements were moved from
  PageContext.
- Removed constants PAGE_SCOPE, REQUEST_SCOPE, SESSION_SCOPE and
  APPLICATION_SCOPE as these are duplicated in PageContext.

jsr152/src/share/javax/servlet/jsp/tagext/BodyTag.java
- Clarified that in a classic tag invocation with an empty body
  (e.g. ), the body methods are not to be called by the
  container.

jsr152/src/share/javax/servlet/jsp/tagext/TagLibraryValidator.java
- A validator operates on the XML view associated with the JSP page,
  not the "XML document".

jsr152/src/share/javax/servlet/jsp/el/VariableResolver.java
- Removed pContext parameter from resolveVariable()

jsr152/src/share/javax/servlet/jsp/el/ExpressionEvaluator.java
- Changed from an interface to an abstract class.

jsr152/src/share/javax/servlet/jsp/el/Expression.java
- Changed from an interface to an abstract class.

[PATCH] jakarta-tomcat-jasper (ImplicitTagLibraryInfo)

[Mark Roth]

ImplicitTagLibraryInfo incorrectly returned null from getFunctions(). 
The spec requires a FunctionInfo[0] instead.  Returning null also caused 
Generator.generateELFunctionMap to throw a NPE in some circumstances.

Re: [PATCH][JASPER2] Simple patch for one of the resource error messages.

[Mark Roth]

Ryan,

That's correct - according to the JSP 2.0 specification, directives (<%@ 
... %>) are allowed in scriptless bodies (see JSP.1.3.10.1).

- Mark


Ryan Lubke wrote:

I think that the following error message is incorrect:

 - Scripting elements ( <%@, <%!, <%=, <% ) are disallowed here.

Since directives (<%@) are not scripting elements.

[PATCH] jakarta-servletapi-5: javadoc clarifications

[Mark Roth]

Here is a patch with some more javadoc clarifications, to make the API 
more testable.  Thanks go to Ryan Lubke for helping out!

As always, please let me know if there are any questions or concerns.

Change summary:
---

jsr152/src/share/javax/servlet/jsp/tagext/VariableInfo.java
  - Fixed incorrect wording from last patch, for variable
synchronization.

jsr152/src/share/javax/servlet/jsp/tagext/TagExtraInfo.java
  - Fixed wording to preserve forwards compatibility for existing TEI
implementations.

jsr152/src/share/javax/servlet/jsp/tagext/TagInfo.java
  - Fixed default implementation of getVariableInfo() to return a
variable for the id attribute, if specified.
Clarified intent in javadocs.

jsr152/src/share/javax/servlet/jsp/tagext/TagData.java
  - Fixed getId() description, as we're not returning the jsp:id in this
case.

jsr152/src/share/javax/servlet/jsp/tagext/BodyTag.java
jsr152/src/share/javax/servlet/jsp/tagext/IterationTag.java
jsr152/src/share/javax/servlet/jsp/tagext/SimpleTag.java
jsr152/src/share/javax/servlet/jsp/tagext/Tag.java
  - Clarified javadocs w.r.t. variable synchronization

jsr152/src/share/dtd/web-jsptaglibrary_2_0.xsd
jsr154/src/share/dtd/web-jsptaglibrary_2_0.xsd
  - Removed fragment element under variable element, as fragment-scoped
variables are no longer supported.

JSP 2.0's J2SE 1.4 Requirement

[Mark Roth]

It has been brought to my attention that some members of the Tomcat 
community have expressed a desire to see a requirement lower than J2SE 
1.4 in JSP 2.0.

First, let me reassure you that the JSP 2.0 specification is not final. 
  Actually, we are in Proposed Final Draft phase, and we are explicitly 
soliciting feedback!  Early feedback is always much appreciated.  As per 
the cover of the specification, the appropriate forum for feedback is 
[EMAIL PROTECTED]

Regarding the J2SE 1.4 requirement, the expert group discussed the topic 
in early August (as issue "[OTH-17] J2SE Version Requirement") and there 
was concensus from the different experts, but the EG is open to 
additional comments.  You can send mail directly to 
[EMAIL PROTECTED], or, maybe better in this case, talk 
directly to the Apache representatives to the Expert Group: Ricardo 
Rocha ([EMAIL PROTECTED]) and Geir Magnusson Jr. ([EMAIL PROTECTED]). 
In general the more feedback the rep has from his community the better 
for the Expert Group.

For what it's worth, the only technical reasons we require J2SE 1.4 are:

 1. We require support for JSR-45 (Debugging Support for Other
Languages)
 2. We declare support for Unicode 3.0 in our I18N chapter.

Actually, JSR-45 is quite important for the platform as a whole.  For 
example, it was recently pointed out to me that there's a bug report 
against Tomcat 5 because we didn't re-implement the pseudo-debug 
comments that Jasper 1 used to create, and that some tools relied on. 
Standard debugging annotations is an important enabler, and it would be 
a shame to have to wait even longer for it.

 From my perspective, the most significant reason to require J2SE 1.4 is 
that it would be best if people can write portable tag handlers that 
utilize J2SE 1.4 libraries, and be able to use them in any JSP 2.0 
application.  Do we really want to stagnate on J2SE 1.2 APIs forever?

I've compiled a list of new features in J2SE 1.3 and J2SE 1.4 that I 
believe would be of use to page authors and tag library developers that 
would decide to use JSP 2.0.  It would be awesome, IMHO, if page authors 
and tag library developers could rely on these features being present in 
any JSP 2.0 compliant container.  This list was also discussed in the 
Expert Group.

J2SE 1.3 adds (among other features):

 * Built-in JNDI
 * RMI/IIOP
 * CORBA ORB
 * PNG support (for image taglibs)
 * Various Security enhancements
 * Improved socket support
 * HTTP 1.1 client-side support
 * DynamicProxy
 * Serialization enhancements
 * Collections enhancements
 * BigDecimal and BigInteger enhancements
 * StrictMath
 * Timer API
 * Delete-on-close mode for opening zip and jar files
 * JPDA tool support

J2SE 1.4 adds (among other features):

 * XML Processing
 * New I/O APIs
 * Security: Java Cryptography integrated
 * Security: GSS-API, Certification Path API
 * Pluggable Image I/O framework
 * Print Service API
 * Standard Logging APIs
 * Long-term Persistence of JavaBeans
 * JDBC 3.0
 * Assertions
 * Preferences API
 * Chained Exception Facility
 * IPv6 Networking Support
 * JNDI enhancements
 * CORBA ORB with POA
 * *** JSR-45 (Debugging Support for Other Languages) ***
 * *** Unicode 3.0 ***

[PATCH] jakarta-servletapi-5: javadocs, API changes and new file

[Mark Roth]

NEW FILE (in jakarta-servletapi-5.newfiles.tar):
 - jsr154/src/share/dtd/j2ee_web_services_1_1.xsd
   (Required by latest j2ee_1_4.xsd)


CHANGED FILES:

jsr152/src/share/javax/servlet/jsp/JspContext.java:
 - getAttribute(name): Remove IllegalArgumentException
   for non-existent scope parameter.
 - Added javadoc for IllegalArgumentException for
   removeAttribute(name, scope)
 - Added javadoc for IllegalArgumentException for
   getAttributeNamesInScope(scope)
 - Added 'public JspWriter pushBody( java.io.Writer writer );'
 - Moved 'public JspWriter popBody()' from PageContext to JspContext.

jsr152/src/share/javax/servlet/jsp/PageContext.java:
 - forward(path): Remove IllegalArgumentException and
   SecurityException, which are not declared in the RequestDispatcher
   counterpart methods.
 - include(path): Remove IllegalArgumentException and
   SecurityException, which are not declared in the RequestDispatcher
   counterpart methods.
 - include(path, flush): Remove IllegalArgumentException and
   SecurityException, which are not declared in the RequestDispatcher
   counterpart methods.
 - Moved 'public JspWriter popBody()' from PageContext to JspContext.

jsr152/src/share/javax/servlet/jsp/el/ELException.java:
 - Removed toString() method, and constructors pass in localized
   message of root cause Throwable.

 - resolveVariable( name, context ): Add description for
   context parameter.

jsr152/src/share/javax/servlet/jsp/el/ExpressionEvaluator.java:
 - Elaborate on description of what should be passed for the
   expression parameter.  The expression parameter includes
   the tokens '${' and '}', which can appear more than once.
   For example, parseExpression( "Version ${major}.${minor}", ... )
   is valid.
 - Elaborate on caller requirements for passing in a FunctionMapper
   to evaluate() and parseExpression().

jsr152/src/share/dtd/web-jsptaglibrary_2_0.xsd:
 - Escape markup in documentation with CDATA instead of <

jsr154/src/share/dtd/web-jsptaglibrary_2_0.xsd:
 - Escape markup in documentation with CDATA instead of <

jsr154/src/share/dtd/j2ee_1_4.xsd:
 - Escape markup in documentation with CDATA instead of <
 - Make CDATA sections use a consistent style
 - Make xsd:include schemaLocation point to IBM site

jsr154/src/share/dtd/web-app_2_4.xsd:

Re: Ping: sources for jsp2el.jar !

[Mark Roth]

The sources for jsp20el.jar are from the JSTL project.  There's a 
special build target there that produeces this JAR.  We're doing this 
until the EL gets its own project at jakarta-commons or such.

Shawn Bayern should be able to help answer any questions in this area.

[PATCH] jakarta-servletapi-5::Another patch to the JSP XSD files

[Mark Roth]

I just noticed my previous XSD patch from this Monday was never
applied.  Was there a problem?

This patch contains diffs based on the current workspace state, not
based on my previous patch.

This patch contains another few patches to the XSD files.  This affects
both jsp_2_0.xsd and web-jsptaglibrary_2_0.xsd.

Summary of changes:

jsp_2_0.xsd:

- Added id attributes to elements
- Changed (description*, display-name*, icon*) to use 
  common  reference for consistency.  Definition 
  is in common J2EE file.

web-jsptaglibrary_2_0.xsd:

- Added id attributes to elements
- Changed (description*, display-name*, icon*) to use 
  common  reference for consistency.  Definition 
  is in common J2EE file.
- Escaped markup under  elements

Files Modified:

- jsr152/src/share/dtd/jsp_2_0.xsd
- jsr152/src/share/dtd/web-jsptaglibrary_2_0.xsd
- jsr154/src/share/dtd/jsp_2_0.xsd

Oops - did "cvs diff" instead of "cvs diff -u".  Here's a better version
of the patch.  Please use this instead.

[PATCH] jakarta-tomcat-jasper: PFD features and bugfixes 3

[Mark Roth]

Atached is a third patch to move us towards JSP 2.0 PFD
feature-complete.  More to come...

File Changed (IN PATCH)

jasper2/src/share/org/apache/jasper/compiler/Generator.java


Summary of changes:
- Removed TryCatchFinally handling for SimpleTag call generation.
  TryCatchFinally does not apply for SimpleTag anymore.
- Fixed to only declare scripting variables for those 
  variables whose declare attribute is set to 'true' (true 
  by default).
- Scripting variables were not being declared for SimpleTag calls.
  Fixed.
- Fixed Tag Handler implementation to synchronize locally-scoped
  AT_BEGIN and AT_END variables with calling page's page context.

Note that there are a number of spec bugs relating to synchronization
that were discovered while implementing this.  I'll take these findings
to the Expert Group for further discussion.

[patch] jakarta-servletapi-5: Bugfix for 11884

[Mark Roth]

Attached is a bugfix for 11884: getParent in a SimpleTag implementation
returns a Tag.

TagAdapter now works as per the spec.

[PATCH] jakarta-tomcat-jasper: PFD features and bugfixes 2

Attached is a second patch to move us towards JSP 2.0 PFD
feature-complete.  More to come in the next few days...

Files Removed (PLEASE REMOVE MANUALLY):

jasper2/src/share/org/apache/jasper/runtime/JspRuntimeLibrary.java
jasper2/src/share/org/apache/jasper/runtime/PageContextImpl.java


Summary of changes:
- Removed ExpressionEvaluatorManager
- Changed EL validation to use
  ExpressionEvaluatorManager.parseExpression
- PageContextImpl now implements VariableResolver
- Generated Servlet / Tag Handler now implements FunctionMapper
- Implemented getExpressionEvaluator() API - Current implementation
  is very inefficient with all sorts of nasty wrappers, but will 
  get much better once the EL evaluator moves into its 
  own subproject.
- Reworked internal interpreter call to be a proprietary call 
  for the time being, until the EL evaluator moves out of JSTL 
  and into its own project.  Relying on the standard machinery 
  would be too inefficient for the common case.
- Removed prefix map generation, as it's not being used anywhere.
- For tag files, moved creation of JspContextWrapper
  to setJspContext.  Now stores both the original and the 
  wrapped JspContext.  Still need to make sure scripting vars 
  are synchronized with the original JspContext.

I'm open to that possibility, as long as we're able to have then
automatically deployed in Tomcat 5 builds.

Re: VOTE: Restoring Tomcat examples: Which workspace?

[Mark Roth]

The examples, just as in Tomcat 4, are small, portable JSP / Servlet
examples to illustrate how to use these technologies.

Because Tomcat forms the basis of the RI for Servlet/JSP, and because it
is so easy to use, many developers download it to try their hand at
Servlet/JSP development.  I thought it was great how Tomcat 4 provided a
set of pre-deployed examples, ready to go as soon as the server starts
up.

We should continue this for Tomcat 5 (right now the examples links are
broken).  The only question is which workspace to keep them in.

[PATCH] jakarta-tomcat-jasper: PFD features and bugfixes 1

[Mark Roth]

Attached is a patch to move us towards JSP 2.0 PFD feature-complete. 
More to come in the next few days...

- Implemented the value attribute of jsp:doBody for classic 
  tag handlers.
- Stubbed out JspC with getJspConfig() so it compiles.
- Added null check for addInclude() to handle the case where there
  are no preludes or codas.
- Now accepts /WEB-INF/tags as well as /WEB-INF/tags/ for tag file
  default directory.
- ParserController now uses path name to determine if the given 
  element is a tag file instead of searching for tag directive.
- In a tag file, an attribute directive with a fragment attribute
  must not allow a rtexprvalue attribute, and must fix its value 
  to "true".  Fixed implementation to comply with spec.
- Fixed preamble and postamble generator for Tag Files.  Was not
  generating declarations, tag handler pools, methods buffer,
  helper fragment, etc.  Generator now shares code between servlet 
  and tag handler pre and post ambles.
- Even though spec is not clear that they're required, 
  added implicit objects to doTag() so they are available in 
  tag files.

Incidentally, my vote is A, but I'm flexible.

VOTE: Restoring Tomcat examples: Which workspace?

[Mark Roth]

It would be great to restore the examples (both JSP and Servlet) so that
they are deployed on startup and so they are easily accessible.  In the
current build they are broken links.

I also would like to commit a number of additional JSP examples that
illustrate the new features in JSP 2.0.

The default web application that is deployed on startup currently lives
in the catalina workspace.  I have no problems keeping it there, but
before committing such a change I wanted to take a vote on where we
think the examples should live.

Vote:

[ ] A. jakarta-tomcat-catalina
[ ] B. jakarta-tomcat-jasper
[ ] C. jakarta-tomcat-5

[PATCH] jakarta-servletapi-5

[Mark Roth]

The attached archive contains three files that should be added to
jakarta-servletapi-5 to enable parsing of DDs and TLDs without needing
to fetch these schemas from their global URL each time.  Contains:

   src/share/dtd/xml.xsd
   src/share/dtd/XMLSchema.dtd
   src/share/dtd/datatypes.dtd

Please let me know if there are any questions or concerns.

Announcing the JSP 2.0 Preview EA1 Implementation

[Mark Roth]

For those of you tracking the JSP 2.0 specification, we are pleased to
announce the availability of an Early Access Preview implementation, 
available now from:

http://developer.java.sun.com/developer/earlyAccess/jsp/
 
The primary goal of the JSP 2.0 specification is to make JSP technology
more productive and even easier to use.  The specification is being
developed by an expert group consisting of over 30 companies and
individuals, and is currently in Public Review stages.  More information
on the specification, including a public download, is available at
http://jcp.org/jsr/detail/152.jsp
 
This implementation was developed collectively in the Expert Group 
using Tomcat 4.1 and Jasper2 as a base.  The intent of the Expert
Group is to integrate this source base with Tomcat 5.0.
The Preview is intended solely to allow you, the developer
community, to experiment with some of the new JSP 2.0 features and
provide us, the JSR-152 (JSP 2.0) expert group, with hands-on feedback. 
Please send all feedback to [EMAIL PROTECTED]
 
Please note that this is not a production release, and that not all JSP
2.0 features are implemented.

Features implemented include:

* New JSP 2.0 APIs
* Integrated Expression Language Support
* Supports new  and  standard actions
* Supports new SimpleTag Handlers and JSP Fragments

Features not yet implemented include:

* JSR-45 Debugging Support
* Tag Files
* Attributes with Dynamic Names
* JSP Configuration

The download comes with pre-installed JSP 2.0 examples that help
illustrate the new feature set.

Please give it a try, and we look forward to hearing from you!
