Hi,
I am a new member of this community. I have just started using GWT. I
am getting following error while running build script through ant:
Buildfile: /home/viks/workspace/Calculator/build.xml
libs:
javac:
[copy] Copying 1 file to /home/viks/workspace/Calculator/war/WEB-
INF/classes
gwtc:
[java] Compiling module com.mydept.mycompany.client.Calculator"
[java] Finding entry point classes
[java] [ERROR] Unable to find type
'com.mycompany.mydept.client.Calculator'
[java] [ERROR] Hint: Previous compiler errors may have
made this type unavailable
[java] [ERROR] Hint: Check the inheritance chain from
your module; it may not be inheriting a required module or a module
may not be adding its source path entries properly
#################################################
Calculator.gwt.xml file is in same package as Calculator.java. Its
contents are:
<module>
<inherits name='com.google.gwt.user.User'/>
<inherits name="com.google.gwt.i18n.I18N" />
<inherits name='com.gwtext.GwtExt'/>
<entry-point class='com.mycompany.mydept.client.Calculator'/>
<stylesheet src="js/ext/resources/css/ext-all.css" />
<script src="js/ext/adapter/ext/ext-base.js" />
<script src="js/ext/ext-all.js" />
<stylesheet src='Calculator.css' />
<servlet path="/DbaseRPCService"
class="com.mycompany.mydept.server.DbaseRPCServiceImpl"/>
</module>
######################################################
The class Calculator is exactly at the specified package. It is like
this:
public class Calculator implements EntryPoint {
...

}

Looks like the problem is specific to following 2 lines:
[java] [ERROR] Hint: Previous compiler errors may have
made this type unavailable
[java] [ERROR] Hint: Check the inheritance chain from
your module; it may not be inheriting a required module or a module
may not be adding its source path entries properly
I am not able to analyse this situation. I would really appreciate any
help on this.
Thanks.
