Dynamic Include JSP

Hi Everybody,

I have a problem in using dynamic includes by using <jsp:include > tags.

Problem begins :
I want to dynamically include a file in the body subfolder as per code given below :

<----- code begins ----->

<% varincludefile ="body/" + dispov_type_assoc + ".jsp"; %>
<jsp:include page="<%=varincludefile%>" flush="true">

dispov_type_assoc is a variable whose value is coming from database. When the value of dispov_type_assoc is "userkview" , a file userkview.jsp from the body subfolder is included in the page.

But if the dispov_type_assoc value is "dispov_user_view" then it gives the following error message :

<--------- error msg begins -------------->

<-------------- error msg ends--------------------------->

I am using tomcat3.2 server. The various env. settings are as follows :

1) Context path defined in server.xml file is :
<Context path="/adapt"
docBase="/adapt/acm"
crossContext="false"
debug="0"
reloadable="true" >
</Context>
I have tried by changing crossContext value to true also and the error is same.

2) The path and classpath decl. in autoexec.bat file are as follows :
path c:\jdk1.3\bin; v:\jakarta-tomcat-3.2.1\bin;%path%

set classpath = %classpath%;c:\jdk1.3\lib;.;v:\jakarta-tomcat-3.2.1\webapps\examples\web-inf\classes;s:\;c:\winnt;


What could be the possible source of error. I know that in jsp long file names are in dynamic includes are acceptable and even underscores '_' are also acceptable.

Prateek

try restarting tomcat.
I had the same error. It's porbably some bug.
