Configuring JSP's in Weblogic server 7.0

Question

Hi,
I'm trying to port my web application from weblogic server 6.1 to weblogic
7.0. I'm having a little problem with jsp pages in weblogic 7.0. Some of the text
box controls which are populated dynamically in my jsp pages are getting populated
with
"null" value in WL 7.0 e.g. in the following case
<%
String claim_id=null;
%>
<input type=text value=<%= claim_id %> >
on weblogic 6.1 an empty string is printed but in wl 7.0 null is printed as the
value for the text field.
I used the domain configuration wizard in wl 7.0 to make a WLS Domain and then
deployed my application. If I deploy the same application in one of the examples
domain which is installed with Weblogic 7.0 then everything works fine. So its
definity a configuration issue.
Could someone please help me with this.
Thanks,

As per the j2ee 1.2, jsp 1.2 specification mandates that the expressions
default must be "null".
We have introduced a new flag in weblogic.xml called printNulls which is
true by default meaning that "null" will be the default.
Setting this to false makes sure that expressions(<%=expr%> ) with "null"
results are printed as "" (earlier behavior)
Here is how to configure the printNulls from weblogic.xml :
<weblogic-web-app>
<jsp-param>
<param-name>printNulls</param-name>
<param-value>false</param-value>
</jsp-param>
</weblogic-web-app>
