title: Problems requiring rJava in Windows
body: <p>I am using a 64-bit machine, with the latest version of R (3.1.2), the latest RStudio version (0.98.1091) and the latest JAVA (Version 8 Update 31).</p>
  
  <p>I tried to require rJava (rJava_0.9-6) and the result is the following error:</p>
  
  <pre><code>require(xlsx)
  Carregando pacotes exigidos: rJava
  Error : .onLoad falhou em loadNamespace() para 'rJava', detalhes: 
  chamada: fun(libname, pkgname)
  erro: No CurrentVersion entry in Software/JavaSoft registry! Try re-installing Java and make sure R and Java have matching architectures.
  Failed with error:  ‘package ‘rJava’ could not be loaded’
  </code></pre>
  
  <p>I already tried to re-install Java with no sucess.</p>
  
  <p>Does anybody know how can I solve this problem?</p>
