Java error

[Tatyana Deryugina]

I'm using twitter2stata on a new computer and it's throwing the following Java Error:

java.lang.ClassNotFoundException: com.stata.drd.stTwitter
at java.net.URLClassLoader.findClass(URLClassLoader.j ava:381)
at java.lang.ClassLoader.loadClass(ClassLoader.java:4 24)

at com.stata.Javacall.load(Javacall.java:119)
at com.stata.Javacall.load(Javacall.java:90)

I ran "query java", as suggested by some other posts, and it seems like Stata can find Java, though I have to admit that I don't fully understand the output (pasted below). Any ideas?

Update: the "ssc install twitter2stata" did not work properly (a necessary .jar file was missing). Following the "net install" instructions on this blog fixes the error: https://blog.stata.com/2017/07/25/im...ta-into-stata/
