Gwt spring getthreadlocalrequest null
GWT requires an interface and a matching asynchronous interface for clients to use. The value returned from the Service interface is now the generic value passed into the AsyncCallback. This class extends GwtController and implements the Service interface.
Example 4. The constructor sets up the asynchronous service. The callback is used to process the results or a failure if there is a problem with the request. This isn't the best for performance, but seemed the easiest way to leverage Spring Security's JSP tags for evaluating whether or not someone has permission to delete a record. Spring by Example.

Please note that in the above example:. Another remark about URL path segregation. In this case, we just need to modify our servlet method extractServiceURL to extract the trailing part with.
It should be injected in the servlet as init parameter. In the GWT sample code from Google, the RemoteService implementation is also an extension of RemoteServiceServlet, so you have access to inherited methods from this class and its supers in your service implementation. This is required for many things you might want to access in your service implementation, such as headers, session, context, etc.
Was thinking have not tried of extending the RemoteService interface to include something like setServlet HttpServlet , which could be called as necessary just before RPC. Your RemoteServices would then of course implement this extended interface and regain access to servlet methods. Of course you can extend the RemoteService with some methods of your own. The blog is very helpful. Can you please provide the code snippet for setServlet HttpServlet and how to class this.
You are so cool! So good to discover another person with a few unique thoughts on this subject matter. If the parameter called input contains a name you should rename it to name to express its purpose. Method names should be verbs. I would rename greetServer to serveGreeting or doGreeting.
It's pretty obvious from the code itself, so I'd remove the comment. Clean Code by Robert C. Martin : Chapter 4: Comments, Noise Comments. I'd move the complete validation logic to the FieldVerifier class or another helper class or helper method for better reusability and higher abstraction.
It also would make the greetServer method more compact. See also: Effective Java, 2nd edition , Item Know and use the libraries The author mentions only the JDK's built-in libraries but I think the reasoning could be true for other libraries too.
IllegalArgumentException is a RuntimeException , so declaring them in the method signature is not mandatory, you could omit it:. Sign up to join this community.
