Run jar with reference to specific java version
<p>I got an exception running XMLspark.jar because of my JRE version configured in the system.</p>

<p>How can i suggest another java that is residing in my system?</p>

<pre><code>C:\Program Files\XMLSpark\XMLspark&gt;java -jar XMLspark.jar
Exception in thread "main" java.lang.UnsupportedClassVersionError: base/MainWind

<p>This is the .bat file that runs the jar:</p>

<pre><code>java -jar XMLspark.jar
