the concurrent access issue.Therefore, you need to reset the call status each time. The best place is in the dostarttag method. * The tag will never call release () during the call (); * Do not use the bodycontent object in the setbodycontent method or the doinitbody method. It is only used to obtain the object and prepare the object. * If you use empty or non-empty tags for custom tags that implement the bodytag interface, an exception is thrown. Because empty labels do not call some methods.
