Now I have a requirement that my project accept some args from other system then my system post the args to alfresco explorer and return the result to other system. How can I do this? I will very appreciate someone help me.
Well when you say post the argument to the explorer what exactly you mean. I think you can use the webscripts with arguments to respond to the arguments with specific results.
In fact,I need accept a set of parameters with username and password,then registered to the alfresco, last return result to the other system. success or fail.
Then you can use alfresco's authentication service to check that given credentials are valid or not it will automatically return you the status success or failure which in turn you can return back.
