Why you should care

[/vc_column_text][vc_column_text pl=”0″ pr=”0″ pt=”0″ pb=”0″]JSP fragments are a portion of a JSP code passed to a tag handler so it can be invoked as many times as required. They can be considered as a template that is used by a tag handler to produce customized content. A fragment attribute is evaluated by a tag handler during tag invocation unlike a simple attribute which is evaluated by the container. One can define the value of a fragment attribute by using a .jsp attribute element.

However when JSP fragments are left incomplete, they cannot be made accessible for client browsers as it can cause readability issues and a symptom for flawed programming practices[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/2″][vc_column_text pl=”0″ pr=”0″ pt=”0″ pb=”0″]

Business Impacts

Incomplete JSP fragments are risky because they do present improper programming practice which will be greatly unappealing to potential clients.

How we detect

[/vc_column_text][vc_column_text pl=”0″ pr=”0″ pt=”0″ pb=”0″]This code insight shows JSP fragments that are not complete pages should not be made not accessible for client browsers.
But : it is a polemic diag, as explained here : “Some people also believe in putting them under the WEB-INF folder, so that they’re not accessible via a URL. I see no good reason to go to this extreme, since there’s no way to discover their existence from outside of the app-server. On the other hand, there’s a decided maintainability benefit to keeping refactored fragments together with their including file.”
