The following table describes properties for the sun-web-app element.
Table A–126 sun-web-app Properties
Property |
Default |
Description |
---|---|---|
false |
If true, resources in this web application that are symbolic links are served. You can also define this property for a virtual server. Web applications on the virtual server that do not define this property use the virtual server's value. For details, see virtual-server in Sun Java System Application Server 9.1 Administration Reference. ![]() Setting this property to true on Windows systems exposes JSP source code. |
|
none |
Specifies an alternate document root (docroot), where n is a positive integer that allows specification of more than one. Alternate docroots allow web applications to serve requests for certain resources from outside their own docroot, based on whether those requests match one (or more) of the URI patterns of the web application's alternate docroots. If a request matches an alternate docroot's URI pattern, it is mapped to the alternate docroot by appending the request URI (minus the web application's context root) to the alternate docroot's physical location (directory). If a request matches multiple URI patterns, the alternate docroot is determined according to the following precedence order:
For example, the following properties specify three alternate docroots. The URI pattern of the first alternate docroot uses an exact match, whereas the URI patterns of the second and third alternate docroots use extension and longest path prefix matches, respectively. <property name="alternatedocroot_1" value="from=/my.jpg dir=/srv/images/jpg"/> <property name="alternatedocroot_2" value="from=*.jpg dir=/srv/images/jpg"/> <property name="alternatedocroot_3" value="from=/jpg/* dir=/src/images"/> The value of each alternate docroot has two components: The first component, from, specifies the alternate docroot's URI pattern, and the second component, dir, specifies the alternate docroot's physical location (directory). Spaces are allowed in the dir component. You can set this property for all the web applications on a specific virtual server. For details, see virtual-server in Sun Java System Application Server 9.1 Administration Reference. |
|
true |
If true, allows this web application to access the contexts of other web applications using the ServletContext.getContext()method. |
|
false |
If true, allows this web application to send a relative URL to the client using HttpServletResponse.sendRedirect(), and instructs the web container not to translate any relative URLs to fully qualified ones. |
|
false |
If true, sessions generated for this web application use the session ID specified in the request. |
|
true |
Set this property to false to ensure that for this web application file downloads using SSL work properly in Internet Explorer. You can set this property for all the web applications on a specific virtual server. For details, see virtual-server in Sun Java System Application Server 9.1 Administration Reference. |
|
5 |
Specifies the maximum number of servlet instances allocated for each SingleThreadModel servlet in the web application. |
|
domain-dir/generated/j2ee-apps/app-name or domain-dir/generated/j2ee-modules/module-name |
Specifies a temporary directory for use by this web module. This value is used to construct the value of the javax.servlet.context.tempdir context attribute. Compiled JSP files are also placed in this directory. |
|
false |
If true, response headers are encoded using the response’s charset instead of the default (UTF-8). |
