Can't load DataSources - SmartClient runtime not loaded

[Isomorphic]

Please make use of the previously mentioned documentation (our Debugging & SuperDevMode docs).

A reminder that these docs already include a troubleshooting section. If you need further help, you should indicate which of the troubleshooting steps you performed, and what the result was.

Hi,

I cannot load the datasource.

Below is the console log from eclipse.




ERROR DataSourceLoader - BaseServlet Global Exception

javax.servlet.ServletException: DataSource 'supplyItem' failed to load due to an exception on the server:

class org.apache.xerces.parsers.XIncludeAwareParserConfiguration cannot be cast to class org.apache.xerces.xni.parser.XMLParserConfiguration (org.apache.xerces.parsers.XIncludeAwareParserConfiguration is in unnamed module of loader com.google.gwt.dev.shell.jetty.JettyLauncher$WebAppContextWithReload$WebAppClassLoaderExtension @344e49fd; org.apache.xerces.xni.parser.XMLParserConfiguration is in unnamed module of loader 'app')

See the server-side log for additional details.

As the previous poster said: just follow the instructions. There is even a troubleshooting guide.

There is no point in customizing this error message as your should be ensuring your end users never see it. It can only happen if you completely botch your project setup.

[nareshbharti]

Hi , I have a similar requirement where i want to change that custom error message (can't load dataSource ) , can you please explain little more how this issue was get resolved .

Many thanks in advance .

[mayun]

i resolve the problem. Change the ide to MyEclipse and follow the instruction ,all things is ok

[mayun]

Isomorphic hi isomorphic,can you help me? thank you ! ;)

[mayun]

Isomorphic hi Isoomorphic,i'm very very appreciate your help and your patience!
1. i'm running in Intellij IDEA using the GWT plugin ,here is my project screenshot



2. when i start with debug ,there is no exception or error generated ! please see my debug configurations:



3.The browser startup with these error




4. The New Tab




as the error tell me ,the isc is not defined ,but i 'm confused with the load sequence

Thank you again Isoomorphic!!! Best Wishes!

[Isomorphic]

The screenshot shows that the Framework files are in the wrong location. They should be at http://127.0.0.1:8888/builtinds/sc/modules

Are you running in Eclipse using the GWT Plugin, or building your app from the command line?

[mayun]

[mayun]

Isomorphic hi, i just use the sample: built-in-ds ,and js has been included into the BuiltInDs.html

    <script> var isomorphicDir = "builtinds/sc/";</script>  
    <script type="text/javascript" language="javascript" src="builtinds/builtinds.nocache.js"></script>
    <script type="text/javascript" language="javascript" src="builtinds/loadScriptTagFiles.js"></script>

When i visit the url path:here is screenshot ,so i'm very confused!

[Isomorphic]

The logs are telling you exactly what's wrong and what to fix:
