Scriptlet in STRUTS 2

[Kartik Talasu]

Hi am using a scriptlet in JSP of Struts 2, but am not able to get the value in textfield. Below is the code which i have used

<%
String str=request.getAttribute("tDate").toString();
%>

<s:textfield value=<%=str %> name="toDate" id="toDate" />

Its showing an error like "Missing quotes for attribute value"

You should try <s:textfield value="<%=str %>">.

Surely the tags in Struts2 support EL so you should avoid scriptlets and do something like this instead:

<s:textfield value="${tDate}" />

I'd also be a bit surprised if this really isn't even the best way. Most tag libraries in the popular frameworks pull in data from the request and bind it back automatically. But I don't know enough about Struts2 to say how in this case. But the above example *should* work.

Hi Gregg,

I tried with your statement but its giving error like
<s:textfield value="${tDate}" name="toDate" id="toDate" />


org.apache.jasper.JasperException: /jsp/ToDate.jsp(4,0) According to TLD or attribute directive in tag file, attribute value does not accept any expressions

If the value is an action property just use OGNL. If it's really in the request then also use OGNL.

hi david, i have both ways like

<s:textfield value="${tDate}" name="toDate" id="toDate" />

and

 <%  
   String str=request.getAttribute("tDate").toString();  
   %>  
   
  <s:textfield value=<%=str %> name="toDate" id="toDate" />  

Both none of the things had worked, if you dont mind could you give the exact syntax how to use OGNL

Hi David,
I tried with the OGNL also but it is not displaying any value, instead of value it is displaying the code.
But if am using property instead of textfield its working fine.

 
<s:textfield name="fromDate" theme="simple" value="#request['hello']" />

<s:textfield name="fromDate" theme="simple" value="#request.hello" />

I had used both the ways but still no luck. Instead of value its displaying "#request.hello"

But its working for property

  

<s:property value="#request['hello']"/>

<s:property value="#request.hello"/>

hii i have a same problem how to get struts 2 property?

[David Newton]

Try wrapping the expression in the OGNL escape %{}.

@Sandy: what's a "Struts 2 property"? In other words, be specific. Better yet, start new threads for new topics, and TellTheDetails.

[David Newton]

@Kartik: wait, are you trying to access *parameters*?! Use #parameters then, otherwise you're attempting to access *attributes*. But in general you should never need to access a request parameter directly in a JSP-why are you doing this?

I hope Kartik is still not stuck with this problem after almost 1 year ...

LOL, hadn't noticed Sandy woke a sleeper.
