title: "Java not found" in using tabula-py
body: <p>everyone, I am using tabula-py in python to extract table from pdfs. I used following codes. </p>
  
  <pre><code>import tabula
  
  table_temp = tabula.read_pdf('./example_pdf/sample1.pdf',pages=11)
  </code></pre>
  
  <p>However, I got the error message as pasted below, in which I was told "no such file or directory: 'java'". I have installed Java in the following folder </p>
  
  <pre><code>"/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home". 
  </code></pre>
  
  <p>Could anyone help me on solving the problem? </p>
  
  <p>Thanks. </p>
