Re: Ajax Servlet Deployment
If you are aren't on a recent version of Wonder, you need to be for this to
work - Ajax in servlet. Probably fixed about a year ago.

Hi,
I am attempting to deploy a web page where the page uses an
AjaxFlexibleFileUpload component. This works in the development setup.
However, once the page with the AjaxFlexibleFileUpload loads on the server
the two XHRs that run come back with 200 responses but they are completely
empty of content. This results in no file dialog appearing when a user
attempts to select an image for upload.
The errors that show in the browser JS console are
JSONRpcClientException: error parsing result”, ReferenceError: Can't find
variable: jsonrpc_0 and ReferenceError: Can't find variable: jsonrpc_1.
My local development setup is a (reverse) proxy through NGINX. The
deployment is to a AWS Elastic Beanstalk, in Tomcat 7, Java 7 which uses
Apache as a reverse proxy.
I’ll admit I know very little about WebObjects and Ajax. It is not clear
to me that I have all the correct steps for using Ajax components. One
thing I did was to override pageWithName in the Application class.
@Override
public WOComponent pageWithName(String name, WOContext context)
{
log.error(application pageWithName + name + + context);
WOComponent page = super.pageWithName(name, context);
log.error(got page + page);
return page;
}
I noticed that when run locally there is nothing in the logs for the XHR
requests because they load fine. However, when deployed to a Beanstalk
instance I get the following.

I am guessing that this differences means that the ajax requests are not
being handled by the Ajax Handler but are getting caught by the default
handler or that they are falling back to pageWithName, (which then falls
back to Main.class) when they should not be?

Re: Ajax Servlet Deployment
Hi John,
Thanks for the tip. I tried that and it wasn’t the issue per say. I also tried
re-ordering the frameworks.
I did finally figure it out. The local development environment used an https
connection and the ElasticBeanstalk one did not. Combined with the secure
cookie property being on in Wonder this meant that the session was not
available to the browser. This seems to have caused the issue.
Thanks for your help.

that run come back with 200 responses but they are completely empty of content.
