Now, I have moved bit further and found out the cause for getting the above mentioned error -
The dbtag lib seems to be conflicting with another taglib (local taglib written for our web-application purpose only).
When I remove that particular taglib it works fine. But I don't know the cause for conflict yet. I don't see any classes with same name or so.....
Any ideas on this???

Hi there!
I am lost all over again (but atleast I could make dbtaglib work)
I recompiled the taglib and when I did a test on it by making a small web app with couple of jsp pages, the taglib worked perfectly well (Hurraaahh!!). But when I placed the jar & tld in the actual web-application I was working on - it started falling over at the same point with same error (panic!! ). I made sure that I am using new jar file. Both of the applications are using same environment - Tomcat4.04. Any ideas with what it could be conflicting?? Any help would be greatly appreciated.

Hi Bill!
Thanks very much for UR reply. I was using TogetherSoft6.0 which was using old API (JSP 1.1).
I will recompile the classes with servletAPI 1.2 - hope it would sort out the error
and I will let U know how it goes. Thanks once again for UR tip.

I am bit confused here...
What I did is compiling the taglib classes along with my other application source files and then packaged taglib classes in jar file. But in this whole process I used only the jar files necessary for the application and nothing like servlet.jar.
I though servlet.jar is used by tomcat during runtime and nothing to do with the application. Can U please tell me if I am mis-understanding the whole concept.
And how should I recompile taglib classes using the servlet API jar files??
Any input would be of great help to me.
Thanks very much

Yeah! I am recompiling the JSPs (as U said), even after that I am getting that problem.
Thanks

Hi there!
I am using Jakarta-dbtags lib for accessing database from client side (jsp). It works fine with Tomcat3.0.4, but when I use the same thing in Tomcat4.0 it's falling over.
The error reads -
javax.servlet.ServletException: (class: org/apache/jsp/log$jsp, method: _jspService signature: (Ljavax/servlet/http/HttpServletRequest;Ljavax/servlet/http/HttpServletResponse V) Incompatible object argument for function call
at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:481)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:853)
...............

..........................
..................................

I don't understand why it's happening as the only thing I did was to move from Tomcat3.0.4 to Tomcat4.0.
In web.xml, within <webapp> tag- I had the <taglib> property & value tag as the last one.
Any ideas what I am missing or where I am going wrong?? For me - It looks like to do with some conflict of jar files in Tomcat or so, but no exact idea
Any help would be greatly appreciated.Thanks.
