Windchill System Administrator's Guide

Relative and Absolute URLs
When using the /bin/windchill java class execution wrapper, you
can add the java arguments that it will use in the wt.java.args property in
wt.properties. To enable HTTPS using this method, set the following in
wt.properties using the xconfmanager utility:
wt.java.args=-Djava.protocol.handler.pkgs=HTTPClient
For further information, see http://java.sun.com/products/JSSE and the
INSTALL.txt file located in the JSSE download.
Prior to Java 1.4, the Java plug-in provides support for HTTPS through the
browser. One shortcoming of this approach is that the JAR files cached for applet
execution require a version number to indicate when updates are available.
Windchill applets include this JAR cache version when wt.properties contains the
following property:
wt.taglib.util.plugin.useCacheVersion=true
The JAR versions are stored in a jar.properties file residing in the same directory
as the requested JAR file. To ensure that the JAR versions are compatible with
Windchill, the following variable in the wt.properties file must be set:
wt.tools.boot.updateVersion=1.3
To rebuild client JAR files and increment the JAR versions, complete the
following steps:
1. Ensure that the wt.taglib.util.plugin.useCacheVersion and
wt.tools.boot.updateVersion properties are set as described earlier in this
section. You can use the xconfmanager utility to display current values and
set values for these properties.
2. Enter the following command from a windchill shell:
ant -f MakeJar.xml
Tip: You can also use this ant command to force a version update so that
clients download all JAR files.
You must restart the servlet engine and method server for the applet tag
generation utilities to pick up the updated version information.
The notion of relative hyperlinks (HREFs) exists only within the context of
HTML pages. In Windchill, relative HREFs are used within static HTML pages
and the static portions of HTML template files. Absolute HREFs are used for all
dynamically generated HREFs.
A typical dynamically generated Windchill HTML page includes the following:
• A tag, specifying an absolute URL to the static Windchill codebase
as configured by the wt.server.codebase property.
