On the assumption that org.apache.http.client.methods.HttpUriRequest is 
not in the same jarfile as your class that calls it, check that:

- the jarfile that contains it will be loaded by your JNLP setup 
  if it isn't present on the target system.

- the jarfile that contains it is listed in your jarfile's manifest

- JNLP is configured to put the org.apache jarfile where the manifest 
  expects to find it - usually in the same directory as the calling
  jarfile or an 'includes' subdirectory.
