CWE-578: EJB Bad Practices: Use of Class Loader

 
EJB Bad Practices: Use of Class Loader
Weakness ID: 578 (Weakness Variant)Status: Draft
+ Description

Description Summary

The program violates the Enterprise JavaBeans (EJB) specification by using the class loader.

Extended Description

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: "The enterprise bean must not attempt to create a class loader; obtain the current class loader; set the context class loader; set security manager; create a new security manager; stop the JVM; or change the input, output, and error streams." The specification justifies this requirement in the following way: "These functions are reserved for the EJB container. Allowing the enterprise bean to use these functions could compromise security and decrease the container's ability to properly manage the runtime environment."
