TA-Lib has a Java binary version.

Can I use this in a Google App Engine project?
The most likely reason that it wouldn't work would be the use of classes that are restricted in the production runtime. Or the use of a library that uses one of those restricted classes.
You can get see list of classes that are allowed here: http://code.google.com/appengine/docs/java/jrewhitelist.html
There is also a list of frameworks and APIs that people have tested here: http://code.google.com/p/googleappengine/wiki/WillItPlayInJava
When you test this and find out, please update this question and the Will It Play wiki.
