 Post subject: Bug in all Downloaders
PostPosted: Wed May 11, 2011 10:20 pm 
I have written a gui for the java grooveshark(tm) downloader and was experiencing some trouble with the method: SearchArtist(searchString).result.result; in GrooveSharkClient.
The function call went into infinite loop. So i tried your original grooveshark(tm) downloader and got following error:

It seems that Grooveshark(tm) has updated something so that your API stopped working.
If you want to check out my gui. It's here http://jokke.bplaced.net/Files/GrooveLoader/
I've credited you in the about window.

Thank you for sending me that error, some other users also noticed it. It seems to be a region specific problem where the grooveshark(tm).com website uses a different api. I really need to fix that :D.
It should be fine if you use a proxy. Seems to be a problem in the US only.

I will take a look at the GUI when I have time, thank you :)

I'm running the program from Germany, so it's not only US. Thanks for looking into it though!

Okay.. Weird.. Now it seems to be working again.. Would it be possible to get the source code for the java api? And/or the javadoc? I would like to change some minor things in the code, like integrating the GrooveFix.xml as a resource into my runnable jar file. For now I've made a workaround, so that the file is actually stored in the jar as a resource and is copied into the running directory if necessary. Still it would be neat to have a single executable without the xml around.

What about distribution.. Can I give away copies of my prog? I've disclaimed copyright to my name, but I'm not sure if this is right? As I've said before, I've credited you in the About page. Is that sufficient? Will GrooveShark(tm) sue me?? I've been careful only to mention the name with the (tm) sign.

Another thing: I've implemented multithreaded downloading of the songs. It seems to work a lot faster than cued downloads. Maybe you should consider doing that in the next version of your Downloader for Windows. Just an idea. In the mean while I will try to clean up my code and document it properly so that you can actually make some sense out of the source, if you're interested. :P It's pretty quick 'n' dirty for now.

Sorry, most of this is clearly off topic. I didn't want to open up a thread for all of this.

The GroovesharkClient class has a second argument where you can pass the groovefix xml content as String.
It´s funny because I build pretty much the same as a Eclipse View:

Thx SciLor for your awesome work!
Would be nice if the playlist would be also accessible via the Java API.
