[MicroEmulator-dev] Mapping source code to eclipse.

[Naveen DS]

Hi,
Can someone explain how to map the microemulator's source code in
eclipse.

[Bartek Teodorczyk]

Hi,

There is a special maven task create initial .project and .classpath files:

mvn eclipse:clean eclipse:eclipse -DdownloadSources=true

Then use Eclipse "Import..." feature, minimum module set is
microemu-cldc, microemu-midp, microemu-javase, microemu-injected,
microemu-javase-swing.

I did as above, and mapped to eclipse, now when i select a text(eg. a
class name),right click on it and clicking on "open declaration" , i
get dialog box saying "the resource is not on the build path of the
java project". To understand key parts of the code, If we select and
double click on a method or class will open its declaration. How to
get this ??

Hi,
Where will the .classpath and .project files be created ? I did the
same and used eclipse to import, and I selected the microemulator-
readonly folder into eclipse. But still, cross (x) symbol is coming
in red near the lines of code(Means there is error of dependancy)..
Can you provide me a solution.?
Thanks ..

Eclipse files .project and .classpath are created in this Maven task:

mvn eclipse:clean eclipse:eclipse -DdownloadSources=true

[Bartek Teodorczyk]

What specific class are you trying to open with open declaration?

Thanks a lot for replying sir, I did the same as you have said above. After that I clicked on "import Project" and in corresponding window , I selected ,"Existing projects into workspace" and selected /microemulator-readonly/microemulator as root of the project. Then Eclipse starts importing, but is reporting many errors saying classes are missing. How to get around this problem.?

Which classes are missing?

BR,

I dont think its the problem of missing classes(classes were missing from build path actually), so I used another way of importing the project. What I did was .. 

  1. Created a new Java Project.

  2. Then did this, File->Import, and in the next dialog under , General , selected File System. 

  3. In the next window, I selected the root folder ie.. "microemu-read-only".

 Then all the files were imported into the workspace(with no errors).

Now the problem is,  I was reading the file MIDletAccess.java inside microemu-midp, and when I right clicked on DisplayAccess on the line 35 and selecting "open declaration" gives a dialog box saying "The resource is not on the build path of the project". When I checked with other files also , I am getting the same problem.. See the screenshot provided here .. What needs to be donce to get around this problem and how to compile and run the project .. ?? 

Thanks ..

[Bartek Teodorczyk]

MIDletAceess.java has to be in a build path. To do that in Eclipse, right click on "java" label:

"java"
-> javax
-> org
   -> microemu
      -> (...)

and select "Build Path" and "Use as Source Folder"

You mean the "Java" Label in the Package Explorer ?? Or where is the Label..

[Bartek Teodorczyk]

Exactly, the "Java" Label in the Package Explorer.

I did as the same and should i do for all files ?? I am getting the same error in all files .. And one more thing sir, after I did as u said as above, the MIDletAccess.java moved to the top (in package explorer) under referenced libraries, and if i try to open that , this is the error I am getting ..

[Bartek Teodorczyk]

I really dont know, why you got MIDletAccess.java in the Referenced Libraries tree, that one should be removed.

Did you really added "java" label from Package Explorer to the build path?

"java"
-> javax
-> org
   -> microemu
      -> (...)

BR,

I have removed that one from referenced libraries tree.

I also have added Java(the one inside microemu-midp) into the build path.. after doing this , the contents inside java folder has been removed and is moved to the top. Stil I get lot of cross (red colored) besides every source file. See the screenshot, what is the problem now .. ?

[Bartek Teodorczyk]

Now, it is looking much better :) You are still missing some of the modules in your build path. Now it is time for microemu-cldc/main/java

BR,

[naveen]

Gr8 :) , thanks, I have also added cldc/main/java now and see some yellow color warning(with exclamatory sign). Do  I need add more modules into build path ?

[Bartek Teodorczyk]

Yellow is fine :) You'll need also for sure: microemu-injected, microemu-javase and microemu-javase-swing at least.

I included injected without any problem , but when i included microemu-javase I get error in Injected.java saying "the type injected is already defined", now with many such errors(red colored cross). See this 

[Bartek Teodorczyk]

Remove microemu-injected module, it seems that is no required.

Did that and new error came :( ,

"The import org.objectweb cannot be 

resolved" in the file "changeCallsClassVisitor.java, changeCallsMethodVisitor.java ,classPreprocessor.java"   under microemu-javase

and "The import netscape cannot be resolved" in the file "CookieRecordStoreManager.java" under microemu-javase-swing

Download asm.jar from http://asm.ow2.org/

and "The import netscape cannot be resolved" in the file "CookieRecordStoreManager.java" under microemu-javase-swing

You can just remove that class.

I already have that . Included asm in build path now.. No errors now .. :) Thanks a lot :)
