title: Python 2.7 - JavaError when using grammar-check 1.3.1 library
body: <p>I am trying to use the <code>grammar-check 1.3.1</code> library for Python</p>
  
  <p>I have installed it using the pip commands</p>
  
  <pre><code>$ pip install --upgrade 3to2
  
  $ pip install --upgrade language-check
  </code></pre>
  
  <p>I also unzipped the LanguageTool file from <a href="https://github.com/myint/language-check" rel="nofollow noreferrer">this link</a> and moved it to <code>C:\Users\me\AppData\Roaming\Python\Python27\site-packages\grammar_check</code></p>
  
  <p>Then I tried to run a test program</p>
  
  <pre><code>import grammar_check as gc
  
  with open("file.txt") as f:
      tool = gc.LanguageTool('en-US')
      matches = tool.check(f.read())
      print len(matches)
  </code></pre>
  
  <p>But I got this error</p>
  
  <pre><code>File "lang-grammar-checker.py", line 22, in main
  tool = gc.LanguageTool(predicted)
  File "C:\Users\me\AppData\Roaming\Python\Python27\site-packages\grammar_check\__init__.py", line 190, in __init__

  raise JavaError(u"can't find Java")
  grammar_check.JavaError: can't find Java
  </code></pre>
  
  <p>I also have Java8 installed in my computer. How can I solve this error?</p>
