title: Partner not reached error in JCO.destination
body: <p>I'm Having a problem establishing a connection to SAP in my java program.
  I'm following the examples that come in the JCO download but i always get this error:</p>
  
  <pre><code>    com.sap.conn.jco.JCoException: (102) RFC_ERROR_COMMUNICATION: Connect to SAP gateway failed
      Connection parameters: TYPE=A DEST=ABAP_AS_WITHOUT_POOL ASHOST=xx.xx.x.xx SYSNR=00 PCS=1

  </code></pre>
  
  <p>I don't know what it can be, i'm writing down the correct connection properties (ashost,user,passwd,sysnr,etc).
  Has anybody else has had a problem like this?</p>
  
  <p>This is my connection code:</p>
  
  <pre><code>    Properties connectProperties = new Properties();
      connectProperties.setProperty(DestinationDataProvider.JCO_ASHOST, "xx.xx.x.xx");
      connectProperties.setProperty(DestinationDataProvider.JCO_SYSNR,  "00");
      connectProperties.setProperty(DestinationDataProvider.JCO_CLIENT, "020");
      connectProperties.setProperty(DestinationDataProvider.JCO_USER,   "xxxxxx");
      connectProperties.setProperty(DestinationDataProvider.JCO_PASSWD, "xxxxxxx");
      connectProperties.setProperty(DestinationDataProvider.JCO_LANG,   "en");
      createDataFile(ABAP_AS, "jcoDestination", connectProperties);
  </code></pre>
  
  <p>After that i just instantiate the object with those properties and call the method connect that is written like this:</p>
  
  <pre><code>    JCoDestination destination = JCoDestinationManager.getDestination(ABAP_AS);
      System.out.println("Attributes:");
      System.out.println(destination.getAttributes());
      System.out.println();
  </code></pre>
  
  <p>I'm working on Java, using netbeans, the sapjco3.jar is added to my libraries.
  Do i have to do anything with the dll file that comes? </p>
