RE: Strange behaviour with buffers
Hi, So BEA is telling you that if you say page buffer=64kb and they give you 12kb, that's the spec? ;) Yoav Shapira Millennium Research Informatics -Original Message- From: Jason Irwin [mailto:[EMAIL PROTECTED] Sent: Wednesday, May 19, 2004 5:23 AM To: '[EMAIL PROTECTED]' Subject: Strange behaviour with buffers Apologies if this is in the wrong group, I think that User is the right one. I have noted a difference between how Tomcat (4.0.6 and 4.1.127) and WebLogic (7.0 and 8.1) assign buffers, and I'm trying to figure out which one is correct. I have an outer page that does not define any buffer, and an inner page that does, e.g.: outer.jsp html body Outer buffer is %=out.getBufferSize()%BR Outer remaining is %=out.getRemaining()%BR jsp:include page=inner.jsp /BR Outer buffer is now %=out.getBufferSize()%BR Outer remaining is now %=out.getRemaining()% /body html inner.jsp %@ page buffer=64kb % Inner buffer is %=out.getBufferSize()%BR Inner remaining is %=out.getRemaining()% Tomcat reports 8kb for outer.jsp and then 64kb for inner.jsp. The remaining buffer sizes are unrelated. WebLogic reports 12kb for both and the remaining buffer are related. It's as if Tomcat creates new JspWriter for each dynamic include, but WebLogic keeps using the same JspWriter. BEA have confirmed that this is their expected behaviour. Is anyone able to confirm if BEA are correct in their interpretation of the JSP Specification and, if so, why Tomcat is behaving the way it does? Is this just a case of a differing opinion on the same spec? I've had a look through the documentation and drawn a blank.

RE: Strange behaviour with buffers
No, they are saying the page buffer declaration in the child include in invalid as it is not supported in the spec. What they quoted at me was: http://java.sun.com/products/jsp/tags/syntaxref.fm7.html It is stated that Note that the page directive does not apply to any dynamic included files;. If I move the directive to the parent, it works (as you'd expect). But what should the behaviour be if the directive appears in the child? BEA claim it will be ignored. And should the parent and child have separate JspWriters, or the same one?

RE: Strange behaviour with buffers
Hi, Ahh, I see what you mean. That's an interesting question, and I'm not a JSP expert (nor am I a huge fan of these low-level buffering directives in the presentation layer in the first place, but that's another story), so I'll let Kin-Man or another expert answer if they feel like it ;) Yoav Shapira Millennium Research Informatics -Original Message- From: Jason Irwin [mailto:[EMAIL PROTECTED] Sent: Wednesday, May 19, 2004 9:00 AM To: 'Tomcat Users List' Subject: RE: Strange behaviour with buffers No, they are saying the page buffer declaration in the child include in invalid as it is not supported in the spec.

RE: Strange behaviour with buffers
That statement from the site is wrong in at least one case: page import May be it's wrong in the other cases too. AFAIK the spec doesn't mention such restriction. (At least I couldn't find it) -Original Message- From: Jason Irwin [mailto:[EMAIL PROTECTED] Sent: Wednesday, May 19, 2004 3:00 PM To: 'Tomcat Users List' Subject: RE: Strange behaviour with buffers Note that the page directive does not apply to any dynamic included files;. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Strange behaviour with buffers
That statement from the site is wrong in at least one case: page import May be it's wrong in the other cases too. Indeed, that did puzzle me. But I am not a Java or JSP expert by any means and BEA's stance is Our behaviour meets the spec, our behaviour is correct. One big problem I had (have!) was finding the official JSP Spec. This link is (I think) to the spec and it seems to refute BEA's stance. But I cannot be sure. http://sunsdlctemp2-vhost1.cambma1-dc1.cscehub.com/servlet/EComFileServlet// ESD6/JSCDL/jsp/2.0-fr/jsp-2_0-fr-spec.pdf?ActionId=verifyTicketId=2aPxkVSIO RtaTicketServerUrl=LxU7fwxQLugy%2BErpKYcvIWlUfSBzPG60JI8nt3z9f3UsBDtcUw13tW 6%2BGroupName=EedEWQ%3D%3D [JSP.1.10.1, 1-43, page 79] A translation unit (JSP source file and any files included via the include directive) can contain more than one instance of the page directive, all the attributes will apply to the complete translation unit (i.e. page directives are position independent).

RE: Strange behaviour with buffers
Hi, Indeed, that did puzzle me. But I am not a Java or JSP expert by any means and BEA's stance is Our behaviour meets the spec, our behaviour is correct. BEA's stance has been like that (and wrong) in the past. That's not a knock on them. One big problem I had (have!) was finding the official JSP Spec. This link Finding the spec is easy: go to http://java.sun.com/products/jsp/reference/api/index.html and scroll down to the Specifications section, click on the Download link next to 2.0-final. It's hard to bookmark the actual download link because it contains session data. My head is beginning to hurt. Jason Dazed and confused Irwin Skip the buffering and skip the headache.

Skip the buffering and skip the headache. Why are you using these include buffering directives in the first place? Legacy. Don't worry. As soon as I have the time to get rid of them, I will!
