RE: Memory consumption of tags

[Wayne Fuller <rw...@ev1.net>]

There is a patch for just this on IBM's site, but only if you are running
Websphere on a NT box.  If you need the URL, I can get it tomorrow at work.

We actually opened a support issue with WebSphere because our JSPs were
generating "Branch too large" exceptions in Websphere but in no other
servers. They told us that there was an optimization in the works that a
client is testing but it is not public yet.

Here is what the jsp compiler generates for each message tag on Websphere
4.0.1:

MessageTag messagetag = new MessageTag();
messagetag.setPageContext(pagecontext);
messagetag.setParent(htmltag);
JspRuntimeLibrary.introspecthelper(messagetag, "key",
"Loginlogout.login.title", null, null, false);
try
{
  int k = messagetag.doStartTag();
  if(k == 2)
    throw new JspTagException("Since tag handler class
org.apache.struts.taglib.bean.MessageTag does not implement BodyTag, it
can't return BodyTag.EVAL_BODY_TAG");

  if(k == 0);

  if(messagetag.doEndTag() == 5)
  {
    return;
  }
} finally {
  messagetag.release();
}
((JspWriter) (obj3)).print(_jspx_html_data[6]);

It doesn't look like too many objects are created, but it seems like there
may be some way to optimize it further.

Thanks,

We plan to do so using WS 3.5.4, and we should
have some load...

you'r frighten me <:(

....

Has anyone running Struts on Websphere noticed these
oddities as well or maybe explain the reason for this?
