Following code is written by me when I learned to write a java backed webscript,it works correctly.There must be something wrong with you code ,you can paste it here.



public class NodeContentGet extends DeclarativeWebScript {
   private static final String PARAM_CONTENT = "content";
   private NodeService nodeService;
   private ContentService contentService;

   public void setContentService(ContentService contentService) {
      this.contentService = contentService;
   }

   public void setNodeService(NodeService nodeService) {
      this.nodeService = nodeService;
   }

   @Override
   protected Map<String, Object> executeImpl(WebScriptRequest req,
         Status status, Cache cache) {
      Map<String, Object> model = new HashMap<String, Object>();
      Map<String, String> templateVars = req.getServiceMatch()
            .getTemplateVars();
      StoreRef store = new StoreRef(templateVars.get("store_type"),
            templateVars.get("store_id"));

      NodeRef nodeRef = new NodeRef(store, templateVars.get("id"));
      if (!nodeService.exists(nodeRef)) {
         String error = "Could not find node: " + nodeRef;
         throw new WebScriptException(Status.STATUS_NOT_FOUND, error);
      }

      String contents;
      ContentReader reader = contentService.getReader(nodeRef,
            ContentModel.PROP_CONTENT);
      if (reader != null) {
         contents = reader.getContentString();
      } else {
         // No content was stored in the version history
         contents = "";
      }
      model.put(PARAM_CONTENT, contents);
      return model;
   }
}
