| 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. On May 20, 2015, at 9:23 AM, John Huss < email@hidden> wrote:
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. On Tue, May 19, 2015 at 4:14 PM Kevin Hinkson < email@hidden> wrote: 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.
ERROR 20:32:35 (com.adnero.finance.web.Application:?) -application pageWithName null <er.extensions.appserver.ERXWOServletContext contextID=0 requestSenderID=0.17.1.1.1.0.1 elementID=null sessionID=GpMB9KKAiBu1Rdv4MqVNu0 request=<er.extensions.appserver.ERXRequest (<er.extensions.appserver.ERXRequest httpVersion=HTTP/1.0 headers={accept=[*/*], accept-encoding=[gzip, deflate], accept-language=[en-us], connection=[Keep-Alive], content-length=[50], content-type=[text/plain], cookie=[JSESSIONID=727EEEFD467421EFD51BB2A65A0707BF], dnt=[1], host=[replaced.host.url], origin=[http://replaced.host.url], referer=[http://replaced.host.url/WebObjects/AdneroWeb.woa/wo/0.0.0.17.1], remote_addr=[104.200.104.189], user-agent=[Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_3) AppleWebKit/600.6.3 (KHTML, like Gecko) Version/8.0.6 Safari/600.6.3], x-forwarded-host=[replaced.host.url], x-forwarded-server=[ip-172-31-26-217.ec2.internal], x-requested-with=[XMLHttpRequest], x-webobjects-adaptor-version=[5.2], x-webobjects-servlet-server-name=[replaced.host.url], x-webobjects-servlet-server-port=[80]} content-length=50 cookies=null userInfo={ServletConfig=org.apache.catalina.core.StandardWrapperFacade@7f127e0, ServletContext=org.apache.catalina.core.ApplicationContextFacade@6970e732, HttpServletRequest=org.apache.catalina.connector.RequestFacade@2b18fb03, HttpServletResponse=org.apache.catalina.connector.ResponseFacade@7507980f} storePageInBacktrackCache=true >) method=POST uri=/WebObjects/AdneroWeb.woa/ajax/0.0.17.1.1.1.0.1 defaultFormValueEncoding=UTF-8 formValueEncodingDetectionEnabled=NO formValueEncoding=UTF-8 formValues={WOIsmapCoords = ("{"id":1,"method":"system.listMethods","params":[]}"); } > response=null pageElement=null pageComponent=null currentComponent=null url="" urlApplicationNumber=-1 distributionEnabled=false pageChanged=false pageReplaced=false>

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?
My apache config for the proxy looks like this:
RewriteEngine On
RewriteCond %{REQUEST_URI} ^/WebObjects/Frameworks/ [NC]
RewriteRule ^/WebObjects/Frameworks/(.+)$ /WebServerResources/Frameworks/$1 [PT]

I am completely lost as to what to try next. Any help in identifying why the Ajax requests are not being handled properly would be appreciated.
