0001583: HTTP request headers displaying on page forwards

Notes
(0001746) byoung 01-23-07 15:03	The problem seems to be with mod_caucho running in apache - if we hit the resin instance directly, there is no problem. We think it has to do with the server outputting whitespace from the forwarding page before the page forward happens.

(0001747) byoung 01-24-07 07:34	We rolled forward with Resin 3.0.22 in our live environment this morning, so you can replicate this error on our live Wap site using a strict browser such as Opera. Here's how: 1) in Opera, hit http://www.upoc.com/wap/. [^] There will be an xml parse error; this is not what we're talking about. 2) Click "Login". I've created a user for you to test with. Username: cauchoTest Password: caucho 3) Click on "Groups" 4) Click on "Your Groups" 5) You should see the error: the page doesn't render, and the HTTP headers are output at the top of the page. I've attached some relevant Java classes. Let me know if you need more info, e.g. the compiled jsp classes.

(0001748) byoung 01-24-07 08:18	There was a previously reported ticket on this: 0000855

(0001749) byoung 01-24-07 10:43	Also, you should try this using the Openwave 7 emulator - I'm using Opera 8.54, which apparently has a tighter xml parser than Opera 9. If you use Openwave 7, you'll see that for the offending page, it has been pointed out that the HTTP headers are displayed twice. Additionally, we're not absolutely certain that this involves forwarding.

JspTemplate.java is the parent class of WapTemplate.java, and that's where the forward(String, boolean) method is defined. Find the attached JspTemplate.java file and the jsp's - here is how they're related: groupsMenu.jsp includes groupsMenuPanel.jsp; groupsMenuPanel.jsp links to groups.jsp; (look for the "Your Groups" text on groups.jsp) groups.jsp forwards to emptyGroups.jsp, which contains the error. The forward happens on groups.jsp - look for template.forward("/wap/emptyGroups.jsp", false); -----Original Message----- From: Scott Ferguson [mailto:ferg@caucho.com] Sent: Wednesday, January 24, 2007 12:31 PM To: Brian Young Cc: Michael O'Dea; totalcare@caucho.com; sales@caucho.com Subject: Re: Resin forwarding bug On Jan 24, 2007, at 7:12 AM, Brian Young wrote: > We rolled forward with Resin 3.0.22 in our live environment this > morning, so you can replicate this error on our live Wap site using a > strict browser such as Opera.

The issue has something to do with the forward or flushing and possibly filters/includes if that's part of the issue. -- Scott > > Best, > Brian
