Hi,everybody! We all know it is not allowed to access file one the server hosting the ejb container throug java.io . But it is said:
Although an enterprise bean must not use the java.io package to attempt to access files and directories in the file system,components should use a resource manager API(Class.getResourceAsStream() returns a InputStream), such as JDBC, to store data.
I wonder which resource manager we can use and how to use.
