Using external libraries in applets
Aug 2nd, 2009, 11:28pm  
So, I've created a cool little sketch that populates a solar system based on how many hits the inputted stuff gets on yahoo.

I want to export it as an applet so I can embed it. Problem is that when it exports as an applet it can no longer use the yahoo search library. How can I let it access this library as an applet?

Classical issue: you need to sign an applet so it can access other Web sites. Just a security problem.

As a follow up to PhiLho's comment on signed applets, you may want to have a look at http://processing.org/hacks/hacks:signapplet to get the work done.

Tried signing it. On exporting there are four .jar files: myapple.jar, core.jar, pyahoo.jar (the yahoo search library), and a yahoo.jar (yahoo made, used by pyahoo.jar.

I can sign every file but the last yahoo jar. I get an error telling me there's duplicate data.  This jar has probably been signed by yahoo. Maybe because I might have 2 different signatures among the jars my applet will run, but wont be able to access it's pyahoo functionality.

I've spent the last couples hours trying to find a way to unsign the yahoo jar so I can resign it. Am I even trying to do the right thing?

Signed jars doesn't need to be signed again (AFAIK). Try signing only the myapple and core jars.

Yep, I can sun it without signing even anything.

I think my problem lies with using this:
http://processing.org/learning/libraries/yahoosearch.html

Has anyone used this in an applet before? How? I'm so lost.
