I'm having trouble calling RPC in shell hosted mode.
Currently I have a simple login page that use rpc to validate the user/
password. And when I tried running with shell hosted mode, it always
give me an onFailure() Error "ERROR"
final AsyncCallback callback = new AsyncCallback() {
public void onSuccess(Object result) {
// take the result coming from the server
boolean ok = Boolean.valueOf(result.toString
()).booleanValue();
if (ok) {
MessageBox.alert("Success", "Successfully logged
in!");
} else {
MessageBox.alert("Invalid", "Your User/Password
combination is incorrect.");
}
}
public void onFailure(Throwable caught) {
MessageBox.alert("Error", "ERROR:");
}
};
>From the error log, i got the following 3 errors.

Seems to me that hosted cannot find my servletclass. Do I need to
copy my classes to my tomcat lite directory such as /tomcat/webapps/
WEB-INF/classes ??
Currently the tomcat lite only has the following files
/tomcat/conf/gwt/localhost/
/tomcat/conf/gwt/lweb.xml
/tomcat/webapps/ROOT/WEB-INF/web.xml
/tomcat/webapps/ROOT/WEB-INF/lib/<all jar files>
/tomcat/webapps/ROOT/WEB-INF/wsdl/
/tomcat/work/gwt/localhost/_/tldCashe.ser
/tomcat/work/gwt/localhost/_/loader/*
Please let me know how to run the rpc popularly~
Thanks!
