title: WildFly: Error on start up
body: <p>I keep getting this silly error, when trying to start up a wildfly server:</p>
  
  <p><img src="https://i.stack.imgur.com/OzN61.png" alt="WildFyl error"></p>
  
  <p>How to fix it? I was googling for like 2 hours now and could not find any solution. 
  My JAVA_HOME is set to C:\Apps\Java\jdk1.7.0_51
  I tried with changing it to jre folder but same error. I also have jdk\bin folder in PATH. </p>
  
  <p>Help me please. </p>
  
  <p>EDIT: Here is the code of batch script. I did not touch it, it camed with the wildfly:</p>
