We have developed a web application through which we are opening forms (designed in Adobe esigner 6.0) in HTML as well as PDF version.
JBoss is used to deploy form server. User through a browser make ca call to WebServer , the call from Web Server to AdobeFormServer is routed by adding an ISAPI filter as 'Jakarta' in WebServer.
Navigation buttons are given in forms to traverse from one page to the other. After the page-level script execution in the form, a java servlet (custom written) is called to render the next intended page.
Sometimes, clicking on a navigation button (say Next Page button), intended page is not opened. Rather, progress bar is shown in the bottom of the page and it continues to show the same as if stuck and java script error is shown in the bottom left of the page as 'this._peer is null or not an object'. This behavior is not consistent.
Initially, we had set IIS timeout in Web Server to 90 minutes and kept jboss3.2.2 timeout as default (which was 20 minutes), so, thought this mismatch to be the reason for same. But even on increasing the session-timeout property to 90 minutes in \\\jboss-3.2.2\server\all\deploy\jbossweb-tomcat41.sar\Web.xml, at times the problem is faced.
This issue is not form specific and is also not consistent. Thus, unable to track the reason for same. Not sure whether its an issue with jboss server configuration or with some coding in form!!
The jboss log says "ERROR [STDERR] com.adobe.formServer.interfaces.ProcessFormSubmissionException: RequestBuffer not specified"
