I am working on file upload/download tutorial from file" target="_blank">www.sdn.sap.com/irj/sdn/webdynpro?rid=/library/uuid/49f2ea90-0201-0010-ce8e-de18b94aee2d#41">file uploading tutorial . First I tried tutorial from point a) . This tutorial is telling how to upload files in netweaver 2004s and How to use new simple type - Resource. But in my case I cannot find such type in com.sap.ide.webdynpro.uielementsdefinitions . And I am absolutley sure that I am using NW 2004s. Maybe some jar file is missing in my classpath?
