Usage

From source file:org.opensubsystems.core.util.servlet.WebParamUtils.java

/**
 * Parse multipart request and separate regular parameters and files. The
 * files names are also stored as values of the parameters that are used to 
 * upload them./*from  w w  w  .  j  a v a 2  s.  c  om*/
 * 
 * @param strLogPrefix - log prefix used for all log output to tie together
 *                       the same invocations
 * @param request - request to get parameter from
 * @return TwoElementStruct<Map<String, String>, Map<String, FileItem>> - the
 *                  first element is map of parameter names and their values. 
 *                  For uploaded files the files names are also stored here as 
 *                  values of the parameters that are used to upload them.
 *                  If there is only one value of the parameter then the value
 *                  is stored directly as String. If there are multiple values
 *                  then the values are stored as List<String>.
 *                  The second element is map of parameter names and the files
 *                  that are uploaded as these parameters.
 * @throws FileUploadException - an error has occurred
