prompt username and password for "Upload Protected Area" in web appl
We deployed a web application in Web AS 6.40 Java SP14. Because of business requirements we decide to skip the authentication of UME and implement our own authentication and authorization by servlet filter. There isn't any container-managed security setting in web.xml. We generated .ear file and deploy it with deploy tool.
Now the strange thing happens. Each time we open a new IE window and give user name and password in login page (kept in our own DB), system pops up a dialog: Enter username and password for "Upload Protected Area"... We have to input the username and password exactly the same as those we use in Connect step to deploy the application in deploy tool then everything is fine. We notice that in Security Provider of Visual Administrator there is a security role '$SAP_J2EE_Engine_Upload'. If we remove it from web component in Security Provider, the dialog still appears but we have no way to login.
Could anyone give a hint why this happens and what is the workaround?
Many thanks in advance
