clearTagStateForTagPoolingServers
protected void clearTagStateForTagPoolingServers()Description copied from class:StrutsBodyTagSupport
Provide a mechanism to clear tag state, to handle servlet container JSP tag pooling behaviour with some servers, such as Glassfish.Usage: Override this method in descendant classes to clear any state that might cause issues should the servlet container re-use a cached instance of the tag object. If the descendant class does not declare any new field members then it should not be strictly necessary to call this method there. Typically that means calling the ancestor's
ComponentTagSupport.clearTagStateForTagPoolingServers()
method first, then resetting instance variables at the current level to their default state.Note: If the descendant overrides
StrutsBodyTagSupport.doEndTag()
, and does not call super.doEndTag(), then the descendant should call this method in the descendant doEndTag() method to ensure consistent clearing of tag state.- Overrides:
clearTagStateForTagPoolingServers
in classContextBeanTag
