Subject RE: org.apache.jasper.compiler.CompileException: ... Unable to co nvert a String to java.util.Vector for attribute imgList
Date Wed, 04 Jul 2001 13:52:21 GMT
Vinay,
 
my tag library accepts a Vector not a String.
This format "<%=imgList%>" according to my book should pass the Vector
Object to the tag library.
I have tried it on a different jsp server (resin1.2.1) and it worked fine,
but when I run it on the tomcat I get this error
 
Still looking for the answer.
 
Many thanks for all that are helping me out.
 
N.

"<%=imgList%>"
would return a String wouldn't it? Its just the return of the toString
method I guess. Is that what your tag library accepts? Or does it need a
Vector at that position?

Hi Suresh, 
 

I am using a JSP tag where I like to send a Java object to the java class.
 
The jsp file is 
 
<%@ taglib uri="clientSkin.tld" prefix="iclient" %>
<%
 Vector imgList = new Vector();
    imgList.addElement("bla bla");
%>
<iclient:head imgList="<%=imgList%>"
/>
 
and the error I get is
 
org.apache.jasper.compiler.CompileException: FILE_TO_BE_RUN.jsp(16,0) Unable
to convert a String to java.util.Vector for attribute imgList

So the jsp file sees to be ok in terms of type casting. I think the error is
more towards the tomcat server.

Anyone has an idea ? Would appreciate any help.

I feel that there is problem with the type casting.
There should be something like  (java.util Vector) vector_variable =
(java.util Vector) string_variable
 
Try to put (java.util Vector) before string variable. Hope it works

I have tried to look into the documentation of the
org.apache.jasper.compiler.TagBeginGenerator, 
but I haven't seen much there. Any idea that can point me in teh right
direction ?
