Re: GWT Eclipse Plugin is not compatible with Eclipse 2022-03

[Abhishek Yadav]

Hi All

You can use the GWT eclipse plugin which is made compatible with latest 
version of eclipse 4.26(2022-12) by someone from the GWT community. I am 
providing the link below.

*http://keeitsi.com/software/eclipse-plugins/ 
*
I am using this plugin and it works perfectly fine on the latest version of 
eclipse.

 Currently, the Eclipse side is up to 202103, and seems to be up to 
 JDK1.8.

 The official documentation still only describes this plugin, so I'd 
 like you to add a method with the Moven plugin as soon as possible.
 (Preferably with illustrations)

Serialization error due to different folder structure on local and server machine

[Abhishek Yadav]

I am getting following error in my server tomcat logs:-

*ERROR: The serialization policy file 
'/nos/js/4937711D6147993DCFE47FF203A0FEDC.gwt.rpc' was not found; did you 
forget to include it in this deployment?*
 
On my local machine the above path is present and tomcat is able to locate 
it and hence I don't get this error. All the folders are present inside nos 
folder.

But on server, all the folders are present inside ROOT and nos folder is 
not present and hence server tomcat is not able to identify this path

I am providing folder structure on my local machine and server below :-



*Windows folder structure   Directory: 
C:\Users\abc\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\nos*

Can anyone suggest how can I make consistent folder structure between

Let me know if my understand is incorrect ?

Re: GWT 2.10.0 release

Hi Priya,

GWT 2.10 has dropped support for  IE 8, 9, and 10. So it will not work 
unless you modify the Sencha GXT 2.3.1.a.jar

Re: Your src appears not to live underneath a subpackage called 'client',but you'll need to use the directive in your module to make it accessible

[Abhishek Yadav]

Hi Jen & Thomas,

I was able to resolve that issue but now I am stuck at a different issue.

Now my project structure related to webapp is below as folllows:

MavenProjectName

src/main/webapp
  gxt -> Some folder and files 
  js  -> Some folder and files '
 index.html
 proj.css
src/main/webapp/WEB-INF
 web.xml   -> Some servlets, their mappings and index.html 
in welcome-file-list tag

Scenario 1)
Now If I start codeserver then from the GWT eclipse plugin then it does not 
allows me to use  -noServer flag and it gives me a url *http://127.0.0.1:9876/ 
*after starting super dev mode 
and then displays message*:* *Visit a web page that uses one of these 
modules*
After selecting one of the link it displays a empty page on the browser and 
in the logs 
GET /nos/js.nocache.js
   Sent error page: not found:

Scenario 2)
Now if I run super dev mode from gwt eclipse plugin then it gives me an 
ClassNotFoundError for javax.sql.datasource
1)So is my folder structure correct to dispay the application host page ?
2) Also is there any documentation on how to use external servlet container 
along with super dev mode in eclipse plugin 

Can you let me know on this issue

Re: Your src appears not to live underneath a subpackage called 'client',but you'll need to use the directive in your module to make it accessible

[Abhishek Yadav]

Hi Jen,

I have changed my entry point to
class='com.cname.proj.client.Main. But now super devmode is  now giving
me an error not able to find com/cname/proj/client/Main.gwt.xml in the
classpath. It forces me to keen Main.gwt.xml and Main.java in the same
folder/package and then it is giving me forgot to inherit some module
error.



Thanks & Regards,
Abhishek Yadav
