Jason and Craigo, I apologize for not replying earlier. When I first
asked about mixing projects, I was at a stage where I had just broken
one of the projects that made up the larger project I was working on.
Under the pressure of delivering some working software for the client,
I put "doing things properly" on hold. In fact, to fix the broken
project, I created a new project, and copied all the pieces, one at
time, from the broken project into the new one, and things worked.
I'm happy that it got things working, but not happy when I don't
understand what's going on, nor how to do things properly.
Ok, in the hope that somebody is still willing to lend some advice, I
have created two projects: the most simple, trivial GWT projects that
I can make.
STEP ONE --------------------
Project TestA was made using the Eclipse GWT project creator, then I did:
1. in the src branch, delete server and shared folders
2. delete the test and test-classes folder
3. in the client folder, delete these classes/interfaces:
GreetingService
GreetingServiceAsync
4. fix errors in TestA.java until all that's left is:
imports, plus
public class TestA implements EntryPoint {
public void onModuleLoad() {
Label label = new Label("hello");
RootPanel.get("nameFieldContainer").add(label);
}
}
5. in the war branch, take the servlet parts out of web.xml
6. under Project > Properties > Java Build Path > Source tab, remove
the test part, which was deleted.
I set the -noserver option, and run with a lampp setup. Set the
apache server to consider the war folder as a document root directory.
It works.
STEP TWO ---------------------
Made another project, TestB, exactly the same as above
STEP THREE -------------------
To project TestB, I added a custom widget that I will want to use in
other projects, such as TestA. It is a simple class called NewDialog,
which extends the GWT DialogBox.
STEP FOUR ----------------------
Here is where I'm stuck. I can't get the "Link Source" to work. Not
only doesn't it work, it seems to behave differently depending on what
day of the week it is (if you get my drift).
Starting with (for TestA) Project > Properties > Java Build Path
there are tabs for Source, and Projects. The Link Source option
appears on the page with the Source tab.
Question 1: Should I also be adding TestB to the Projects page?
Question 2: When using Link Source, the Source page originally shows:
TestA/src
Then, on the Link Source dialog, if I enter:
/home/john/workspace/TestB/src
it says "The folder is already a source folder"
If I specify the linked location even deeper, like:
/home/john/workspace/TestB/src/com/axxessible/testb/client
it says "The folder 'TestA/client' already exists."
In each of these situations, I'm sitting there saying, "Yeah, I
know--so what!?" Obviously, I'm missing a fundamental point here.
Can you point me in the right direction?
John
