porting code from eclipse to processing
Feb 25th, 2006, 9:15pm  
I am not sure if this is an appropriate section to ask this question but here is the problem I have. I am using del.icio.us API to get some posts and tags etc. which is to be visualized in processing, right now I managed to to everything in the backend and I am thinking to port this code to processing so that I can start to build the front end and connect these two. I have copy pasted all the code from eclipse to processing and also I have put my external jar files which are needed for API in my /code folder. When I try to run the code it is giving this error:

java.lang.ClassCastException
at processing.core.PApplet.main(PApplet.java:5486)

I have later added import processing.core.*; on top of my every class and the extensions for the tabs are .java.
So what do you guys think of this, am I on the right track to transfer my code to processing, should I follow another way, any suggestions would be awesome!

thanks in advance

I´m not sure about copy/pasting java code into processing since processing generates the code again from the sketch, hence the troubles first you ran into...
but anyway, wouldn't it be better if you made a library from ecplise and included it into sketch ?
this works well

that's a great idea only If I knew how to make a library in eclipse! I could leaqrn it, I am going to learn it but since this project is supposed to be finished by Tuesday, I am leaning towards more practical solutions.

Anyway here is what I did, I imported my processing core.lib file into my project and build a new class that extend PApplet and thaw works, so that I am thinking to draw the stuff here on Eclipse (I don't know if I can get away with that) I can draw shapes without problem but when it comes to font I tried to draw a font on the screen in eclipse and it simply didn;t work. It was first giving me the error of putting the font in a data folder error, that's what I did, I created a data folder in eclipse workspace and put my font in there, now it is not giving me that error but still giving me error while running the applet error.

So I am thinking this could be related to PFont class that is dealing with the font.

any thoughts?
(Also my project involves delicious API so creating a library and importing this  into processing would still work in this scheme?)
Thanks in advance!

-- you can export a project from eclipse as a library /jar file ( it gives an option to export a project as a jar library; note: this i simply a zip archive )
-- the ´data folder error´ comes from the fact that processing uses data folder for files but it is relative to actual ´folder´ the sketch is run from ( correct me somebody pls if I am wrong )
so you would find out what is actual folder eclipse runs your program from ( can be also set in Run - Paramaters for an actual Run configuration in eclipse )
-- your delicious api is, in fact, a reason why you would deploy it as a library and use as such in processing since this functionality si not there...
regards,
aph
