jsp - hidden element - null to empty string

Hi, I have written following jsp in weblogic 8.1

<%
String sss = null;
%>
<form>
<input type="hidden" name="tx" value="<%=sss%>">
</form>
Checking Hidden null values ....

After deploying the jsp the view source shows the hidden element as
<input type="hidden" name="tx" value="">

but in websphere is shows as <input type="hidden" name="tx" value="null">

how is the null replaced with empty string in case of web logic when I am not doing any transformation.

Please help...

Thanks in Advance

The JSP compiler is doing that for you.

These days, it's better to use the features of JSP 2.0.
The newer JSP EL expressions ${sss} will automatically convert nulls to empty strings for you.

Note: The Jasper compiler used to do this with JSP expressions but stopped when Tomcat 5.0 came out. I'm not sure but I think Weblogic uses Jasper as its JSP compiler.

Hi,

Thanks for your response. I found that the following code in weblogic.xml is doing this

<jsp-param>
<param-name>printNulls</param-name>
<param-value>false</param-value>
</jsp-param>

Is there anyway to do the same in Websphere. I am migrating my application from Weblogic to Websphere.

Thanks in Advance

Not sure but I'll move this to our Websphere forum for you.
