Method Detail

getParameter

public String getParameter(String name)

Fixing Vaadin upload problem on Weblogic. During upload Vaadin reads parameters from request first and then access inputStream for uploaded data. However on Weblogic, reading parameters from request consumes whole stream, so later data are not accessible from inputstream. This approach in WL is valid, as stated in servlet API for ServletRequest.getParameter(String) If the parameter data was sent in the request body, such as occurs with an HTTP POST request, then reading the body directly via getInputStream() or getReader() can interfere with the execution of this method. In this case, Vaadin reads parameters only to show warning if WidgetsetVersion is not the same as Vaadin version... so irrelevant during upload. Fixed by overriding request that prevents invocation of getParameter() method if running on WL during 'upload' request.
