Thanks. It worked ...
There is another problem i am facing in invoking a servlet named blobserve
as follows -
<IMG
src="blobserve?SQL=select+blob+from+apply_images+where+image_name='formimage
'"></IMG>
This servlet is supposed to accept a SQL query as parameter, execute it and
return the result .I get this error when i invoke the servlet .
javax.servlet.ServletException: executeQuery requires a non-NULL SQL
statement
at blobserve.processRequest(blobserve.java:81)
at blobserve.doGet(blobserve.java:128)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:740)
However if i break up the SQL query in 2 parts and pass 2 parameters , SQL1
& SQL2 which are concatenated in the servlet , it works.
<IMG src="blobserve?SQL1='select blob from apply_images where
image_name'&SQL2='university'" ALIGN="TOP"></IMG>
What could be the reason for the above ?
Thanks in advance,
Shruti

Try without the forward slash . So it looks like this:
<FORM METHOD="GET" ACTION="auditor">
