Hi,
If your  JAVA Application is Web based application, you can expose it as Webservice.
JAVA People will pick the data from Dbase using their application and will send the data to XI by using our XI Details like Message Interface and Data type structure and all.
So we can Use SOAP Adapter or HTTP in XI..
If you use HTTP for sending the data to XI means there is no need of Adapter also. why because HTTP sits on ABAP Stack and can directly communicate with the XI Integration Server Directly
If you are dealing with the Webservice and SAP Applications means check this
