JMS

[Fraser Goffin]

Are there any plans in the near term to support JMS. Those of us using Restlet 
in Enterprise environments often require asynchronous and highly reliable 
protocols offered by one of the popular messaging backbones (MQ) ??

Are there any plans to support JMS transport any time in the near future. Those

Error while parsing simple plain text fields in multipart form at Restlet 1.1

[webpost]

Hi everybody!
I have some troubles with parsing simple plain-text form fields in Restlet v1.1

The form looks like
form action=/restletServlet method=post enctype=multipart/form-data
  textarea name=simpleField rows=10 cols=100Simple text 
content/textarea
  input type=submit value=post
/form

I've tried to parse multipart request from my resource as in the example at 
http://wiki.restlet.org/docs_1.1/13-restlet/28-restlet/64-restlet.html page 
(with some simplification):


// 1/ Create a factory for disk-based file items
DiskFileItemFactory factory = new DiskFileItemFactory();
factory.setSizeThreshold(1000240);

// 2/ Create a new file upload handler
RestletFileUpload upload = new RestletFileUpload(factory);
try {
   upload.parseRequest(request);   // LINE X
} catch (FileUploadException e) {
   e.printStackTrace();
}

The following error occurs:

java.lang.NullPointerException

Also, when I've tried pure Apache code instead of code above:


// Create a factory for disk-based file items
FileItemFactory factory1 = new DiskFileItemFactory();

// Create a new file upload handler
ServletFileUpload upload = new ServletFileUpload(factory1);

try {
upload.parseRequest(ServletCall.getRequest(request));   // LINE X
} catch (FileUploadException e) {
e.printStackTrace();
}


, I have following error:

Using a REST layer for UI and services

[webpost]

Hi everyone,

I have a web app who is divided into a web services and a ui front end. 
Actually the ui is made from servlets who call a business services layers and 
my web services use the same business layer.
But I wonder if it is a way to write a set of REST services for replacing the 
old web services and using these REST for the ui too.
Does someone have some usefull tips or experience about that ?

Thanks
