  <p>I compiled this program and created the jar file</p>
  
  <pre><code>./javac -classpath /folder/postgresql-8.4-703.jdbc3.jar -d /Samplejavaprogram/classes /Samplejavaprogram/src/Sample.java
  ./jar -cvf /Samplejavaprogram/Sample.jar -C /Samplejavaprogram/classes/ .
  </code></pre>
  
  <p>Jar has the following manifest file</p>
  
  <pre><code>Manifest-Version: 1.0
  Created-By: 1.7.0_06 (Oracle Corporation)
  Main-Class: Sample
  Class-Path: /folder/postgresql-8.4-703.jdbc3.jar
  </code></pre>
  
  <p>also contains file /folder/postgresql-8.4-703.jdbc3.jar. I launched Sample.jar by means of a command</p>
  
  <pre><code>./java -jar -Djava.library.path=/opt/jdk1.7.0_06/lib /Samplejavaprogram/Sample.jar
  </code></pre>
  
  <p>and as a result I received the following messages</p>
  
  <pre><code>Connection Failed! Check output console
  java.sql.SQLException: No suitable driver found for jdbc:postgresql://192.168.1.8:5432/NexentaSearch

      at java.sql.DriverManager.getConnection(DriverManager.java:221)
      at org.myorg.Sample.main(Sample.java:33)
  </code></pre>
  
  <p>I launched the file from a host with the address 192.168.1.10, and on a host 192.168.1.8 it fulfilled normally.
  Help to eliminate an error.</p>
