Standard: An Implementation of the JSP™ Standard Tag Library (JSTL)
Version: 1.1.0-B1
Release Notes
The Standard 1.1.0-B1 release is an
implementation of the JSTL 1.1 Specification.
Given that JSTL 1.1 has a dependency on JSP 2.0, an official release of
JSTL 1.1 will happen once the Final Release of the JSP 2.0 specification is
published.
The Standard Taglib, which is hosted at Apache, is used as the source repository for the JSTL reference implementation supplied by Sun Microsystems, Inc.

fmt:formatNumber now removes the scoped variable when the
value is null or empty.
|
|
|
c:param now encodes URL with URLEncoder.encode(str, encoding)
|
|

Advisory character encoding now properly fetched from "charset" attribute
of "content-type" header (required change to spec) |
|
|
Fixed processing of Locale when variant is used.
|
|
|
<sql:setDataSource> did not allow the specification of a scope without
a var attribute to set the SQl DataSource configuration setting. Fixed.
|
|
|
Page scope not properly set with <c:if>. Fixed.
|
|
|
Config.find() fails on invalidated sessions. Fixed.
|
|
|
Consistent use JspTagException: (1) always include original exception when
available. (2) use ex.toString() instead of getMessage().
|
|
|
Type conversion rules now properly applied when setting a bean property using
<c:set>.
|
Other changes and additions:
- Added Version class to easily tell the version of the jar file.

February 2003 • Standard 1.0.3
Bugs fixed since Standard 1.0.2 Taglib release:
|
Bug Id
|
Summary |
|
|
Tag-handler reuse discovered a bug in 's processing of default
values. This bug was fixed by initializing an instance variable
in doStartTag().
|
|
|
We revisited this bug prompted by a
report from a user of the J2EE RI and adjusted the EL implementation to
accommodate the J2EE RI's default security restrictions.
|
|
|
Minor display-related bug in ScriptFreeTLV
|
|
|
There still was a bug when the fmt:message tag was pooled
and reused, and a bundle was not specified explicitely.
|
|
|
Added <uri> definition in WEB-INF/jstl-examples.tld for
/jstl-examples-taglib.
|
|
|
If is used to set a property of a bean, and a setter method
does not exist for that bean, a NullPointerException was thrown.
A JspException with an appropriate error message is now thrown instead.
|
|
|
The tag handler for <fmt:requestEncoding> was not resetting the encoding value it picks up from the
javax.servlet.jsp.jstl.fmt.request.charset session attribute between invokations.
|
|
|
We now expose the exception object thrown by a bean property evaluated by the
EL (not just the exception message).
|
|
|
Improved the exception message when there is a failure accessing an absolute URL.
|
|
|
Fixed minor typos in standard-examples.
|
Other changes and additions:
- Fixed minor typos in JSTL API Javadoc documentation.
- Added TLV examples (scriptFree and PermittedTaglibs)
- Fixed minor typo on standard/examples/web/xml/ForEach.jsp
- Improved Japanese localization
13 October 2002 • Standard 1.0.2 Taglib released
Bugs fixed since Standard 1.0.1 Taglib release:
|
Bug Id
|
Summary |
|
|
The fmt tags used to store the BodyContent
from one tag in the same field variable they use for value. This caused problems
in a container that supported tag re-use since the old BodyContent was used. |
|
|
The xml:transform tag can now be used with a series of imported
stylesheets. |
|
|
There was a bug in the EL grammar that caused attribute values like "$${X}" to be parsed as a single string instead of a string followed by an expression. |
|
|
The <c:url> value attribute and the
<c:redirect> url attribute are required as defined in the JSTL specification. |
|
|
According to the JDBC specification, a null can be passed to the PreparedStatement.setObject() and the parameter will be set to JDBC NULL properly. The broken PreparedStatment.setNull() call has been removed.
|
|
|
There was a typographical error in our sample TLDs for the PermittedTaglibTLV and ScriptFreeTLV validators.
|
Other changes and additions:
- Wrapped number formatting examples that use browser-based locale inside . Now the parse
exception that occurs with "de_DE" locale due to a bug in
java.text.NumberFormat
(Bugtraq bugid: 4709840) can be documented appropriately.
- The "jsp20el.build" target was modified so that the JSTP 2.0 EL packages were renamed to avoid potential
JSTL 1.0 conflict.
- Root cause now exposed when an EL expression evaluation fails.
- New regression tests for the EL parser.
26 July 2002 • Standard 1.0.1 Taglib released
Bugs fixed since Standard 1.0 Taglib
Final release:
|
Bug Id
|
Summary |
|
|
Fixed 'xslt' attribute for <x:transform>
to only accept an
object exported by <x:parse> if it's a String,
Reader, or
javax.xml.transform.Source. |
|
|
Added "UNICODE_INPUT = true"
to the ELParser.jj
options so that non-ascii values can be parsed. |
|
|
GettingStarted.html guide updated to include
all jar dependency information. |
|
|
SQL examples updated to allow for the inputting of dataSource
username and password. |
|
|
c:url tag no longer prepends path to page
relative URLs. |
|
|
Added a <welcome-file-list> element
to the example application's deployment descriptor. Modified standard-doc
in a corresponding fashion. |
|
|
BundleSupport modified to use the current context classloader
instead of the classloader that loaded it. This change was necessary
in order for BundleSupport to properly find resources
in a web application.
The SQL DataSourceWrapper also modified to properly
use classloader delegation to load resources.
|
|
|
Fixed incorrect x:param error message. |
Other changes and additions:
- Improved
x:parse action's EntityResolver to
work with JAXP 1.2. URI's normalized so they can be processed consistently.
- The JSTL 1.0 Specification
has all the official functional descriptions; out of date documentation
removed.
- Hard-coded and browser-based locales separated into distinct pages in
order to avoid conflicting response encodings.
- Formatting web application examples updated to use EL to access request
parameters.
query and update tags modified to catch a more
generic JDBC driver implementation generated exception when it occurs and
provide a meaningful error message.DateParam tag modified to have an empty body content as defined
by the spec.PreparedStatement.setNull(parameterIndex, java.sql.Types.NULL)
now used when specifying null parameter values.- XPath performance improved by caching parsed representations of XPath
expressions.
- Support for relative system ID's in
<x:transform> simplified.
- Improved
TimeZoneSupport javadocs
- Added Japanese resources
- Added support for JSP
2.0 functionality in the JSTL EL. By default, none of the new features
are enabled in order to comply with the JSTL
1.0 Specification. The functionality will be triggered by a particular
way of calling the interpreter.
- Created new new "
jsp20" parser directory.
- Added new "
jsp20el" build target for JSP
2.0 specific features.
- Added copy of
*.properties to JSP
2.0 EL jar.

Final Standard Taglib 1.0 release
17 Jun 2002
Standard Taglib RC1 released.
19 Apr 2002
Standard 1.0 Beta2 released, which is compliant with the JSTL Proposed Final Draft.
12 Mar 2002
Standard 1.0 Beta1 released, which is compliant with the JSTL Public Review Draft.
12 Dec 2001
Standard 1.0 EA3 released. Version includes the following
changes and additions:
- Introduction of SQL tags ("sql:*" library).
- A performance improvement to the XML "transform" tag.
- Minor changes and bug fixes to the i18n and XML libraries.
- Distribution JAR files are now 'standard.jar' (RI) and 'jstl.jar'
(API).
- showSource.jsp no longer depends on raw file I/O (and so
should work even when standard-examples is deployed as a WAR).
21 Nov 2001
Standard 1.0 EA2 introduced. Version includes the following
major changes and additions:
- JSPTL has been renamed to JSTL.
- The "jsptl" library at Jakarta Taglibs has been renamed to
"standard."
- Tags for text inclusion and URL encoding introduced.
- Tags for i18n-capable text formatting introduced.
- Tags for XML manipulation introduced.
- JSTL now divides functionality among multiple TLDs. Each TLD represents
a cohesive unit of functionality, such as "XML manipulation" and
"formatting." 'jx' and 'jr' are no longer used; they are replaced
with shorter abbreviations for the common cases (e.g., 'c', 'x').
- ECMAScript is now the default expression evaluator. Since the
first release of 1.0 EA1, new languages include JXPath and ECMAScript.
- The RI has been thoroughly repackaged; many classes have moved.
- The package name for the JSTL API is now javax.servlet.jsp.jstl
and is subdivided into cohesive packages. (The old package for the
API was javax.servlet.jsptl.)
- A small number of minor changes were made to the code. By and large,
these changes are not significant; the easiest way to discover
further details is to look at the CVS archive itself.
