RE: Memory consumption of tags

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.

Subject: RE: Memory consumption of tags


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,
dave dandeneau

Has anyone running Struts on Websphere noticed these

RE: Memory consumption of tags

2002-02-22 Thread Johannes Carlén 

Well, actually, look at the code Tomcat generated:

org.apache.struts.taglib.bean.WriteTag writeTag = new
org.apache.struts.taglib.bean.WriteTag();
writeTag.setPageContext(pageContext);
writeTag.setParent(_jspx_th_html_html_0);
writeTag.setName("testBean");
writeTag.setProperty("value");
try {
int result = writeTag.doStartTag();
if (result ==
javax.servlet.jsp.tagext.BodyTag.EVAL_BODY_BUFFERED)
throw new JspTagException("Since tag handler class
org.apache.struts.taglib.bean.WriteTag does not
implement BodyTag, it can't return
BodyTag.EVAL_BODY_TAG");
if (result != javax.servlet.jsp.tagext.Tag.SKIP_BODY)
{
do {
// end
// begin
[file="/testWrite.jsp";from=(16,0);to=(16,46)]
} while (writeTag.doAfterBody() ==
javax.servlet.jsp.tagext.BodyTag.EVAL_BODY_AGAIN);
}
if (writeTag.doEndTag() ==
javax.servlet.jsp.tagext.Tag.SKIP_PAGE)
return;
} finally {
writeTag.release();
}

It doesn't make any calls to the introspecthelper
method at all. It sets the attributes on the tag
directly. So websphere does some extra work here...
Could this be recognized as a bug? Or is it just an
"old" way of handling tags?

Well, as I understand, it is further down, in the call
to the JspRuntimeLibrary.introspecthelper() method
that the objectc get created...

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.

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.
