      Description

      While evaluating template with Velocity I am affecting:

      java.lang.NullPointerException

      exception.

      Code which is being executed:
      try

      { Velocity.init(); }

      catch (Exception e1)

      { e1.printStackTrace(); }

      then

      try

      { Velocity.evaluate( context, writer, "string", template.getSzablon()); }

      catch (ParseErrorException e)

      { e.printStackTrace(); } catch (MethodInvocationException e) { e.printStackTrace(); }

      catch (ResourceNotFoundException e)

      { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); }

      This code does not on production server, but works on development machines. I have tried using VelocityEngine instetad of Velocity Signleton but no luck.

      I also tried initializing Velocity during servlet startup but nothing changed. Any help appreciated
