Hi,

>Only a type can be imported. org.cris.prime.bl.ConsLicBl resolves to a

package

Could you show us the import statements of your JSP ?
It looks like the problem could be there.

(as if you had declared "import org.cris.prime.bl.ConsLicBl.*; or something
like this)

Regards,

Arnaud

Hello Arnaud,

i'm sorry for the late reply.well here's the statement that i'd used in
my ConsLicResult.jsp :-

<%@ page import="org.cris.prime.bl.ConsLicBl"%>

i'd given the whole path as above,but then also it is unable to find
ConsLicBl.java.why?
should i send you my code of ConsLicResult.jsp,ConsLicBl.java and
DBConnection.java.
as i'd imported DBConnection.java in ConsLicBl.java and finally this
file in ConsLicResult.jsp.
i'd done everything to solve this problem.but nothing came out.My
directory structure is like :-

C:\Program Files\Apache Software Foundation\Tomcat
5.5\webapps\testing\ConsLic.jsp
C:\Program Files\Apache Software Foundation\Tomcat
5.5\webapps\testing\ConsLicResult.jsp
C:\Program Files\Apache Software Foundation\Tomcat
5.5\webapps\testing\WEB-INF\classes\org\cris\prime\bl\ConsLicBl.java
C:\Program Files\Apache Software Foundation\Tomcat
5.5\webapps\testing\WEB-INF\classes\org\cris\prime\db\DBConnection.java

Problem is coming in ConsLicResult.jsp as it is unable to resolve
ConsLicBl.java.

Kindly help.
Looking forward for your kind reply.
Thanks & regards,
Vidhi

Well, the thing which comes to mind, is that you have the .java files
in your WEB-INF/classes dir, try putting the .class files inthere
instead.
