HTMLB in NWDS do not display visible controls in the EP

I created a JSPDyn program in NWDS that include the following jsp code

<hbj:content id="myContext" >

<hbj:page title="Primer Ejercicio de HTMLB">

<hbj:form id="myFormId"

method="post"

target="_blank"

encodingType="multipart/form-data"

action="/htmlb/servlet/com.sap.htmlb.test.MyTestJsp1Test">

This form submits to a new web client window

<br>

because of 'target=_blank'.

<br>

<br>

<hbj:label

id="label_InputName"

required="TRUE"

text="ZIP Code"

design="LABEL"

labelFor="InputName"

/>

<hbj:inputField

id="InputName"

type="string"

maxlength="100"

/>

<br>

</hbj:form>

</hbj:page>

</hbj:content>

But when i enter to the EP to see the result in the iview i can not see the visible controls label and inputfield Does i need configure something previusly to run the ivew? in order i can see the visible controls.
