Overview of Changes in Sun ONE Web Server 6.1

Chapter 5 Migrating from Version 6.0 to 6.1 71

Symbolic Links in Configuration Files (UNIX and

Linux)

Symbolic or relative links in server configuration files may cause problems when

upgrading. Make sure that server configuration files that contain absolute

references to files under the server root always reference the path to the server root

in the same way. Preferably, these links should not transverse any symbolic links.

Web Applications

In the 6.0 version of the Web Server, information pertaining to web applications

was stored in the

server.xml file and the web-apps.xml file. The web-apps.xml

file is not supported in Sun ONE Web Server 6.1, and web application data is now

stored in the following files:

•

server.xml

•

web.xml

•

sun-web.xml

•

obj.conf

The VS (virtual server) element in the server.xml file in Sun ONE Web Server 6.1

now contains a

WEBAPP (web application) element for every web application it

hosts. The attributes of the

WEBAPP element are consistent with the mechanism used

in Web Server 6.0 to configure web applications and are dynamically

reconfigurable, that is, they don’t require a server restart in order for changes to be

applied to the server instance.

For every web application, the deployment descriptor file,

sun-web.xml, is created

in the

<web-application>/WEB-INF directory. The deployment descriptor file is

based on the schema file,

sun-web-app_2_3-1.dtd, which is compliant with the

Servlet 2.3 specification. This schema file is also located in the

<web-application>/WEB-INF directory.

In the 6.0 version of the Web Server, if you used the web-apps.xml file to tune

certain server parameters, for example, reap interval (which specifies the number

of seconds between checks for expired sessions), now, in Sun ONE Web Server 6.1,

you would perform an identical function using the

sun-web.xml deployment

descriptor. Example:

In Web Server 6.0:

<init-param>

1 2 ... 66 67 68 69 70 71 72 73 74 75 76 ... 93 94
