You can use a custom tag or create a temporary view structure like this:

public class FunctionView {     String functionName;     List<SubFunctionView> subfunctions;      public FunctionView(String functionName, List<SubFunctionView> subfunctions) {         this.functionName = functionName;         this.subfunctions = subfunctions;     }      public String getFunctionName() {         return functionName;     }      public void setFunctionName(String functionName) {         this.functionName = functionName;     }      public List<SubFunctionView> getSubfunctions() {         return subfunctions;     }      public void setSubfunctions(List<SubFunctionView> subfunctions) {         this.subfunctions = subfunctions;     } }  public class SubFunctionView {     String subFunctionName;     Integer value;      public SubFunctionView(String subFunctionName, Integer value) {         this.subFunctionName = subFunctionName;         this.value = value;     }       public String getSubFunctionName() {         return subFunctionName;     }      public void setSubFunctionName(String subFunctionName) {         this.subFunctionName = subFunctionName;     }      public Integer getValue() {         return value;     }      public void setValue(Integer value) {         this.value = value;     } } 

Then you just expost a method called List getFunctionsView() on your controller and use a simple nested jstl foreach loop.

Edit: Had to rework this one slightly.
