Method Detail

getResourcePath

public static String getResourcePath(String path,
                                     boolean pathIsRelative,
                                     String defaultAbsolutePath,
                                     String name)

Get path for resource

Parameters:

path - as String (the path of the file/folder to store the file - relative). If a file it will derive the folder and consume that. If pathIsRelative then this path is expected to be a relative Path to the AppSettings.get().CONTEXT_BASE_ABSOLUTE_PATH Note: the path must exist on the system else the default is returned.

pathIsRelative - as boolean (true if the path is relative to web context)

defaultAbsolutePath - as Default folder path If any problem in knowing web-relative folder path. In the case of Non-Relative URI's this is the base path for the file. For absolute paths this is base path

name - of the Resource

Returns:

appropriate resource Absolute path

handleFileUpload

public static FileUploadHandler.FileMeta handleFileUpload(org.apache.wicket.markup.html.form.upload.FileUpload upload,
                                                          String path,
                                                          boolean pathIsRelative,
                                                          String defaultAbsolutePath)
                                                   throws Exception

Helper to tidy up file Upload code. It uses the webRelativePath to put the uploaded file. If not valid, then uses defaultFilePath. If no file was uploaded it will return null, if there is an exception it will be thrown

Parameters:

upload - as FileUpload File to Upload

path - as String (the path of the folder to store the file) If pathIsRelative then this path is expected to be a relative Path to the AppSettings.get().CONTEXT_BASE_ABSOLUTE_PATH

pathIsRelative - as boolean (true if the path is relative to web context)

defaultAbsolutePath - as Default folder path If any problem in knowing web-relative folder path. In the case of Non-Relative URI's this is the base path for the file. For absolute paths this is base path

Returns:

FileUploadHandler.FileMeta with Final path of file on Server (@nullable true) (relative to web-context(when pathIsRelative=true) else full path to file is returned)

Throws:

Exception
