Thank you for your explanation with so much patience and other warmhearted
guys!
i think i am in the right place!
My enviornment is:eclipse3.3 ,jetty6.1.9,tapestry5.0.6.
At first,i use tomcat,but whenever i changed the code there will be a error
pop up--hot code replace error,so i have to restart the server.it's very
annoy!so,i change to jetty,it's very fast!
BTW,who know how to conquer the "hot code replace error" in tomcat?
I have goolge this error,say i have to use IBM'vm,have i?
when i study t5,i have encountered some problems.the first one is about ASO:
in the page class,i declare a variable:
@ApplicationState
private IDataSource dataSource;//IDataSource is a interface
in AppModule:
public void contributeApplicationStateManager(
MappedConfiguration<Class, ApplicationStateContribution> configuration) {
ApplicationStateCreator<IDataSource> creator = new
ApplicationStateCreator<IDataSource>() {
public IDataSource create() {
return new MockDataSource();
}
};
configuration.add(IDataSource.class, new
ApplicationStateContribution(
"session", creator));
}
the error is:
Failure reading parameter source of component ShowAll:grid:
java.lang.InstantiationException: com.packtpub.celebrities.data.IDataSource
what's the problem?
