EJB Bad Practices: Use of java.io
Last revision (mm/dd/yy): 05/27/2009
The program violates the Enterprise JavaBeans specification by using the java.io package.
The Enterprise JavaBeans specification requires that every bean provider follow a set of programming guidelines designed to ensure that the bean will be portable and behave consistently in any EJB container .
In this case, the program violates the following EJB guideline:
"An enterprise bean must not use the java.io package to attempt to access files and directories in the file system."
A requirement that the specification justifies in the following way:
"The file system APIs are not well-suited for business components to access data. Business components should use a resource manager API, such as JDBC, to store data."
