Re: Compilation error
Looks like I have finally solved the problem.
The case was something like this.
I am using ExtGWT which has a class TreePanel with an inner class
TreeNode, which looks like below:
public class TreePanel {
-
class TreeNode {
---
private M data;
}
--
}
And, since the TreeNode class is public inside TreePanel, I was
directly using TreeNode class in my code.
I would do:
import ..TrePanel.TreeNode;
-
--
TreeNode node = ;
As you can see, TreeNode internally uses the type M, which is not
defined in the above kind of usage.
And GWT compiler gets confused when it sees this.
I solved this problem by removing the import statement as accessing
the TreeNode only in the context of the outer class(TreePanel) like
this:
TreePanel.TreeNode node = x;
This solved the issue.

Compilation error
I just upgraded to GWT 2.0. But when I compile my source code with com.google.gwt.dev.Compiler, I get a NullPointerException as below. What am I doing wrong?

Re: Hosted mode servlets in GWT 1.6
I think I missed an important point in my earlier post. The servlets ARE hosted correctly when I run in hosted mode. But they do not get hosted when I run my junit tests. Here is my web.xml: Sample.html remoteLoggerServiceImpl com.allen_sauer.gwt.log.server.RemoteLoggerServiceImpl remoteLoggerServiceImpl /Sample/gwt-log jUnitHostImpl com.google.gwt.junit.server.JUnitHostImpl jUnitHostImpl /Sample/junithost eventServlet mypackage.EventServlet eventServlet /Sample/eventd When I run the junit tests for my module, this web.xml is not considered at all. But I add a servlet tag to my module.xml as the servlet gets hosted and my unit tests can successfully connect to the servlets. I can even remove web.xml and still it would work fine. What I suspect is that there is some difference in the way servlet mapping are to be specified while running junit tests. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Hosted mode servlets in GWT 1.6
http://code.google.com/webtoolkit/doc/1.6/DevGuideOrganizingProjects.html says the following about tag is the module.xml "NOTE: as of GWT 1.6, this tag does no longer loads servlets in hosted mode, instead you must configure a WEB-INF/web.xml in your war directory to load any servlets needed." What I understand from this is that, I no longer need to supply the tag in the module XML. Instead I can provide the mappig in war\WEB-INF\web.xml. But this does not work for me. If I remove the servlet tag from the module XML, my servlets are not hosted in hosted mode. I really do not want the servlet mapping in the module XML because these servlets are used only for JUnit tests. They are not shipped. Having to specify the mapping in module XML, I have to modify the module XML after I run the tests and before shipping.
