title: Jackson serialization with ObjectMapper in java
body: <p>I want to serialize the different types of lists by using object mapper, but I do not know how to 
    pass the different types of list objects into object Mapper at a time. The following is my code:</p>
  
  <pre><code>AccountingService accService      = ServiceFactory.getAccountingService();
  List&lt;TaxCategory&gt; taxCategoryList = accService.getAllTaxCategories();
  ProductService productService     = ServiceFactory.getProductService();
  List&lt;SimpleUom&gt; simpleUomList     = productService.getSimpleUomsList();
  
  ObjectMapper objMapper;
  objMapper.writeValueAsString(?)--
  </code></pre>
  
  <p>Would You please suggest what I have to pass instead of ? in above code. This is because of i have to get the jackson serialized string that includes above lists as a single string in jsp and parse that string to get individual lists to be used at client side.</p>
