DataSourceLoader. NoClassDefFoundError: com.isomorphic.base.Base

[Amben]

Hi guys,

I spent few days trying to load the most basic datasource into my application without success. Any help would be much appreciated.

using smartgwtee 6.0
and gwt 2.8.0

First : The error :

http://127.0.0.1:8888/MySampleApplic...aSource=testds HTTP ERROR 500

Problem accessing /MySampleApplication/sc/DataSourceLoader. Reason:

Server Error
Caused by:


java.lang.NoClassDefFoundError: com.isomorphic.base.Base at com.isomorphic.servlet.BaseServlet.handleError(BaseServlet.java:203) at com.isomorphic.servlet.BaseServlet.service(BaseServlet.java:164) at javax.servlet.http.HttpServlet.service(HttpServlet.java:729)
and during the compilation : (it doesn't stop the deployment though)

Isomorphic Init: Exception in Init.go()
java.lang.NoClassDefFoundError: Could not initialize class com.isomorphic.util.DataTools


The config :

gwt.xml

<!-- Inherit the core Web Toolkit stuff. -->
<inherits name='com.google.gwt.user.User'/>
<inherits name="com.smartgwt.tools.SmartGwtTools"/>
<inherits name="com.smartgwtpower.tools.Tools"/>
<inherits name="com.smartgwtee.SmartGwtEE"/>

html entry page :

<script> var isomorphicDir = "MySampleApplication/sc/";</script>

Librairies (not maven) :
- gwt-user
- isomorphic_assembly
- isomorphic_core_rpc
- smartgwtee

IDE : IntelliJ
App server : embedded Jetty

I would be very happy to provide any missing info.

Thank you !

Take a look at the list of .jars in the Java Dependencies overview - you've skipped a lot.

As simple as that, can't believe it ! Thank you ! I should have read more carefully. I tried to add the minimum of librairies... bad idea. Now I added all of them :) thanks again

hi again,

I think I still have a config issue. This error happens when I use a checkBoxItem:

GET http://127.0.0.1:8888/images/blank 404 (Not Found)
isc_Canvas__browserDoneDrawing @ ISC_Core.js:2798
isc_Canvas_adjustOverflow @ ISC_Core.js:2804

isc_c_EventHandler_handleMouseUp @ ISC_Core.js:1566
isc_c_EventHandler_dispatch @ ISC_Core.js:1810
(anonymous) @ VM35:3

it is probably due to the theme config. here is mine :

gwt.xml :

 [I]<!-- Inherit the core Web Toolkit stuff.                  --> [/I]
<[B]inherits [/B][B]name[/B][B]='com.google.gwt.user.User'[/B]/>
<[B]inherits [/B][B]name[/B][B]="com.smartgwt.tools.SmartGwtTools"[/B]/>
 <[B]inherits [/B][B]name[/B][B]="com.smartgwtpower.tools.Tools"[/B]/>
<[B]inherits [/B][B]name[/B][B]="com.smartgwtee.SmartGwtEE"[/B]/>

 <inherits name="com.smartgwt.SmartGwtNoScript"/>
<inherits name="com.smartclient.theme.enterprise.Enterprise"/>

main html : same than the one in my initial post.

java :

[B]checkBox [/B]= [B]new [/B]CheckboxItem([B]"checkBox "[/B], [B]"Title"[/B]);
[B]checkBox [/B].setLabelAsTitle([B]true[/B]);
[B]checkBox [/B].setHoverWidth(150);

Do you have any clue about this error ?

Other information : When I first laod the application, the check box is not visible, only the title is, and the error is in the browser logs.

Thank you !

Hi Amben,

please see this post and download a new version if you are on anything older than 2016-12-07.
Also always include your build date in your posts (not just smartgwtee 6.0).

Best regards
Blama

Solved by updating librairies to last version of smartgwt - it was a bug

Same than here
