[4.1.3] SSIServlet:
Complete rewrite of the SSI functionality (WARNING: servlet class name
has changed).

Add support for SSL with the JNDIRealm.
[4.1.16] AuthenticatorBase:
Add a configuration option to disable setting the headers which
prevent proxies from caching protected pages. Using this option may
open security holes in your application, so it should only be used
if you are certain about what you are doing.

by the server.
[4.1.16] AccessLogValve:

for more details.
[4.1.4] Generator:
Fix the limitation on the number of tags which can be used within a

[4.1.19] Compiler:
Added new "fork" option. This tells Ant to fork the JSP page javac
compile so that it is run in a different JVM from the one Tomcat
is running in. Please refer to the Jasper-HOWTO for more information.

An ant Project uses the current directory as its base directory

the original exception and error page mappings in web.xml are not
applied.

============================
KNOWN ISSUES IN THIS RELEASE:
============================
* Tomcat 4.1 and JNI Based Applications
* Tomcat 4.1 Standard APIs Available
* Tomcat 4.1 and XML Parsers
* Web application reloading and static fields in shared libraries
* Enabling SSI and CGI Support
* Security manager URLs
* Symlinking static resources
* Enabling invoker servlet
-------------------------------------
Tomcat 4.1 and JNI Based Applications:
-------------------------------------
Applications that require native libraries must ensure that the libraries have
been loaded prior to use. Typically, this is done with a call like:
static {
System.loadLibrary("path-to-library-file");
}
in some class. However, the application must also ensure that the library is
not loaded more than once. If the above code were placed in a class inside
the web application (i.e. under /WEB-INF/classes or /WEB-INF/lib), and the
application were reloaded, the loadLibrary() call would be attempted a second
time.
To avoid this problem, place classes that load native libraries outside of the
web application, and ensure that the loadLibrary() call is executed only once
during the lifetime of a particular JVM.
----------------------------------
Tomcat 4.1 Standard APIs Available:
----------------------------------
A standard installation of Tomcat 4 makes all of the following APIs available
for use by web applications (by placing them in "common/lib" or "shared/lib"):
* activation.jar (JavaBeans Activation Framework 1.0.2)
* ant.jar (Apache Ant 1.7.0)
* commons-collections.jar (Commons Collections 3.2)
* commons-dbcp.jar (Commons DBCP 1.2.1)
* commons-logging-api.jar (Commons Logging 1.1)
* commons-pool.jar (Commons Pool 1.3)
* jasper-compiler.jar (Jasper 2 Compiler)
* jasper-runtime.jar (Jasper 2 Runtime)
* jdbc2_0-stdext.jar (JDBC 2.0 Optional Package, javax.sql.*)
* jndi.jar (JNDI 1.2 base API classes)
* jta.jar (Java Transacation API 1.1)
* mail.jar (JavaMail 1.3.3)
* naming-common.jar (JNDI Context implementation)
* naming-factory.jar (JNDI object factories)
* naming-resources.jar (JNDI DirContext implementations)
* servlet.jar (Servlet 2.3 and JSP 1.2 APIs)
You can make additional APIs available to all of your web applications by
putting unpacked classes into a "classes" directory (not created by default),
or by placing them in JAR files in the "lib" directory.
Tomcat 4.1 also makes available Xerces 2.9.0 to web applications.
--------------------------
Tomcat 4.1 and XML Parsers:
--------------------------
As described above, Tomcat 4.1 makes an XML parser (and many other standard
APIs) available to web applications. This parser is also used internally
to parse web.xml files and the server.xml configuration file. If you wish,
you may replace the "xercesImpl.jar" file in "common/endorsed" with another
XML parser, as long as it is compatible with the JAXP 1.1 APIs.
---------------------------------------------------------------
Web application reloading and static fields in shared libraries:
---------------------------------------------------------------
Some shared libraries (many are part of the JDK) keep references to objects
instantiated by the web application. To avoid class loading related problems
(ClassCastExceptions, messages indicating that the classloader
is stopped, ...), the shared libraries state should be reinitialized.
Something which could help is to avoid putting classes which would be
referenced by a shared static field in the web application classloader,
and put them in the shared classloader instead (the JARs should be put in the
"lib" folder, and classes should be put in the "classes" folder).
----------------------------
Enabling SSI and CGI Support:
----------------------------
Having CGI and SSI available to web applications created security problems when
using a security manager (as a malicious web application could use them to
sidestep the security manager access control). In Tomcat 4.1, they have been
disabled by default, as our goal is to provide a fully secure default
configuration. However, CGI and SSI remain available.
On Windows:
* rename the file %CATALINA_HOME%\server\lib\servlets-cgi.renametojar to
%CATALINA_HOME%\server\lib\servlets-cgi.jar.
* rename the file %CATALINA_HOME%\server\lib\servlets-ssi.renametojar to
%CATALINA_HOME%\server\lib\servlets-ssi.jar.
* in %CATALINA_HOME%\conf\web.xml, uncomment the servlet declarations as well
as the associated servlet mappings. Alternately, these servlet declarations
and mappings can be added to your web application deployment descriptor.
On Unix:
* rename the file $CATALINA_HOME/server/lib/servlets-cgi.renametojar to
$CATALINA_HOME/server/lib/servlets-cgi.jar.
* rename the file $CATALINA_HOME/server/lib/servlets-ssi.renametojar to
$CATALINA_HOME/server/lib/servlets-ssi.jar.
* in $CATALINA_HOME/conf/web.xml, uncomment the servlet declarations as well
as the associated servlet mappings. Alternately, these servlet declarations
and mappings can be added to your web application deployment descriptor.
---------------------
Security manager URLs:
---------------------
The URLs to be used in the policy file to grant permissions to JARs located
inside the web application repositories have changed in Tomcat 4.1.
In Tomcat 4.0, codeBase URLs for JARs loaded from web application
repositories were:
jar:file:${catalina.home}/webapps/examples/WEB-INF/lib/driver.jar!/-
In Tomcat 4.1, they should be:
file:${catalina.home}/webapps/examples/WEB-INF/lib/driver.jar
---------------------------
Symlinking static resources:
---------------------------
Unix symlinks will not work when used in a web application to link resources
located outside the web application root directory.
This behavior is optional, and the "allowLinking" flag may be used to disable
the check.
------------------------
Enabling invoker servlet:
------------------------
Starting with Tomcat 4.1.12, the invoker servlet is no longer available by
default in all webapp. Enabling it for all webapps is possible by editing
$CATALINA_HOME/conf/web.xml to uncomment the "/servlet/*" servlet-mapping
definition.
Using the invoker servlet in a production environment is not recommended and
is unsupported.
-----------------------------
Using the JSP Compiler (JSPC):
-----------------------------
Using the command line script is not recommended when using JSPC. Instead,
using Ant is supported and encouraged. Please see the Jasper documentation
in the Tomcat documentation bundle for more instructions as well as
a build script.
