Welcome to Stack Overflow. Please take the [tour] and re-visit [ask]. Your question is unclear and we are not so good at debugging code that you didn't show. Add details to your question by using the [edit] link. — rene, Aug 20 '15 at 07:53
I searched for the first one and look what I found: http://stackoverflow.com/questions/22729678/java-compile-error-class-appletprac-is-public-should-be-declared-in-a-file-nam — rene, Aug 20 '15 at 07:55
@rene i have mentioned very clearly that the code is in https://thrift.apache.org/tutorial/java ..Please do , go through it and try to help me out — INIGO, Aug 20 '15 at 09:05
That is not how this site works. You need to provide us with an [MCVE] so future visitors only have to verify if this question matches their situation. They shouldn't have to visit some other site first. The community here has worked out over the last few years that such off-site links are not delivering a good experience. So we all have rules to follow and that includes new users. The [help] is not full of guidance to be ignored. And this might sound all unfriendly and maybe it is but at least seven members found this post unclear, as indicated by the down votes. — rene, Aug 20 '15 at 09:12
And this is not scare you off but you might be interested in [this meta post](http://meta.stackoverflow.com/questions/255583/what-can-i-do-when-getting-we-are-no-longer-accepting-questions-answers-from-th). Stack Overflow is a great place to get help but it only is such a great place because of the strict rules the community has put together over time. — rene, Aug 20 '15 at 09:16

As far as we can deduce from what you've shown, there's a couple of things that go wrong:

There seems to be an issue with your invocation of javac, it is missing a classpath that refers to the Apache Thrift library. You can specify the classpath using the -cp parameter. Make sure it points to the current directory, the Thrift libraries and any other libraries you might be using.
Your class JavaServer should be declared in a file named JavaServer.java (exactly as the compiler error says). Apparently, it's called javaserver.java, which is not the same (at least not on non-Windows platforms).

I changed the file name to JavaServer.java ( same as class name) and now it shows me 28 errors.Can you please suggest me how to check whether thrift library for java is present or not ?? – INIGO Aug 20 '15 at 08:56
The command in your question (`javac javaserver.java`) doesn't show a `-cp` param, so you still need to address the first point. Take a look at [how the Java compiler works](http://docs.oracle.com/javase/8/docs/technotes/tools/windows/javac.html). – mthmulders Aug 20 '15 at 09:05

Sample .thrift files attached to official web tutorial have some errors (July 2015, v0.9.x). Inconsequences in sample struct/classes etc, sample doesn't compile in few languages.

Version of this files in official tar.gz are good.
