Info
Apache Tomcat is the recommended servlet container to use with uPortal 3.2. While uPortal 3.2 requires a Servlet 2.5-compatible servlet container and another servlet container may be used, most uPortal implementers deploy to Apache Tomcat. Choosing Tomcat 6.x will likely allow uPortal adopters to get the best advice from the community.

Installing Apache Tomcat

Linux/Unix Installation

1. Download Apache Tomcat 6.x

...

a. First, start Tomcat

uPortal Specific Notes

Shared Libraries

uPortal places libraries in CATALINA_BASE/shared/lib The default Tomcat 6.0 download does not enable libraries to be loaded from this directory. To resolve this you must edit CATALINA_BASE/conf/catalina.properties and change the line that begins "shared.loader=" to the following:

shared.loader=${catalina.base}/shared/classes,${catalina.base}/shared/lib/*.jar

Shared Sessions

Jasig portlets, as well as many other popular JSR-168 portlets, rely on the ability to share user session data between the portal web application and portlet applications. To enable this feature in Tomcat, you must add the emptySessionPath="true" parameter to the in-use connector (configured in Tomcat 6 in CATALINA_BASE/conf/server.xml ).

<Connector port="8080" protocol="HTTP/1.1"
    connectionTimeout="20000" redirectPort="8443" emptySessionPath="true"/>

GZipping HTML

Browser-side performance may be improved somewhat by GZip-ping downloaded content where appropriate. uPortal 3.2 already GZips CSS and JavaScript. uPortal does not, however, GZip the uPortal page itself.
