Example 1 with FileCleaner

use of org.apache.wicket.util.file.FileCleaner in project wicket by apache.

the class FileUploadTest method getInputStream.

Example 2 with FileCleaner

use of org.apache.wicket.util.file.FileCleaner in project wicket by apache.

the class WebApplication method internalInit.

/**
 * THIS METHOD IS NOT PART OF THE WICKET PUBLIC API. DO NOT CALL IT.
 *
 * Internal initialization. First determine the deployment mode. First check the system property
 * -Dwicket.configuration. If it does not exist check the servlet init parameter (
 * <code>&lt;init-param&gt&lt;param-name&gt;configuration&lt;/param-name&gt;</code>). If not
 * found check the servlet context init parameter
 * <code>&lt;context-param&gt&lt;param-name6gt;configuration&lt;/param-name&gt;</code>). If the
 * parameter is "development" (which is default), settings appropriate for development are set.
 * If it's "deployment" , deployment settings are used. If development is specified and a
 * "sourceFolder" init parameter is also set, then resources in that folder will be polled for
 * changes.
