title: can 32 bit exported jar file be executed using 64 bit java libraries?
body: <p>I export try.jar file using 32 bit java libraries. On the client site, I have 64 bit java libraries. Can try.jar behave 64 bit executable?</p>
  
  <p>For example, I have </p>
  
  <pre><code>Runtime rt = Runtime.getRuntime();
  s = rt.exec("someExecutable");
  </code></pre>
  
  <p>the someExecutable binary is in 64 bit and using this code with 32 bit java libraries seems to be not working. 
  My soln' to this problem is to export  try.jar using 32 bit java libraries (because my enviroment is in 32 bit) and run try.jar using 64 bit libraries in the client site.
  Is this approach correct or any other suggestions?</p>
  
  <p>when I run someExecutable directly (no java involved) which is 64 bit on the client site It works fine (client site is also 64 bit.).
  But when I use s = rt.exec("someExecutable"); It doesnt work. the java libraries (jre executables downloaded over java.sun.com) are now 32 bit at both client and development sites. 
  Do my problem resolve if I install 64 bit libs to client site but not on development site??</p>
