hi

i've imported a complete project in the apple project builder by adding all .java- files in a group(folder). my problem is to get this thing to run. therefor a few questions.

- how can i choose the starting class. the class, in which the project builder shall start the program?
- do i need to make some preferences in my project builder, that it finds the defined packages for import in other .java-files?
- the adding function offers some more options which are 1.copy items into destination group's folder (if needed) 2. reference style 3. recursively create groups ... 4. create folder references .... -> do - and if: how - this options influence the build-process and other things?

thx to all. greets,
granny

how can i choose the starting class. the class, in which the project builder shall start the program?

In the MRJApp.properties file, open it, and where it says "com.apple.mrj.application.main =", should be the first line. After the equals sign, type out the class name that contains the main method. ie:Controller.java, the line should read com.apple.mrj.application.main = Controller

that's the only question i can answer.

The following worked for me last night.

I had a complete CodeWarrior project that would compile and run an application (not applet).
- I created a Project Builder java application with the same name as my .java file with the main method. For example MyJava.java in CodeWarrior called main(String args[]).
- So I created a Project called MyJava.
- I closed the project and moved copies of my codewarrior java files into the folder that PB had put MyJava.java.
- And I replaced MyJava.java with the one from CodeWarrior
- I opend the project back up and added the new files.
- It compiled and ran on first attempt. although this wasn't a very complex application. 5 .java files and maybe 400 lines of code.

does anyone of you know what the message 'cannot resolve symbol' is all about? i get this error msg all the time...

thx,

Cannot resolve symbol seems to be fairly generic. In my limited experience the PB compiler doesn't seem to do as well as the CodeWarrior compiler when it comes to reporting errors.

Anyway here is an example I got. look at what is says the symbol is (in my case it is the method valueOf(int)

What happened was this is an ambiguous method. I had to fully qualify it as 'java.lang.String(int). Also look for where the caret (^) is pointing. I got Cannot Resolve Symbol for a couple different things as well. So you just have to dig.

BtnListener.java:31: cannot resolve symbol
symbol : method valueOf (int)
location: class BtnListener

valueOf(XrowID);

hi, brooky *g*

i've installed my project the way you told me in your second last post. it seems to work (ok - the cannot resolve-error comes a few times, but...) - i probably did something wrong with the add-process of my files last time. the goups were 'blue'-colored instead of the yellow(er) color they've now. (i don't know what this is all about with the color-stuff of groups)...
you were right at the 'resolve-error', i'll try to dig these errors out

do you know an official package called javax.servlet.* ??? it seems that i need to get this package.

thx,
granny

servlet.jar (with javax.servlet.*) is here
http://java.sun.com/products/servlet/download.html

At least I think that's where I got it from. I compiled a servlet in Project Builder a few months ago on the Public Beta. I haven't tried it recently so my memory may be a bit rusty. But I think you just need to get servlet.jar and put it in your CLASSPATH and import javax.servlet.*
