Connecting Tomcat to MSsql

Question

I am new to this and am having trouble connecting to a MSSQL database. I am getting the following error message...
org.apache.jasper.JasperException: /pizza.jsp(11,0) According to TLD or attribute directive in tag file, attribute dataSource does not accept any expressions
     org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:83)
     org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:402)
etc..
Has anybody seen this before?
I have downloaded j2sdk1.4.2_03, Tomcat 5.0 and the JSTL and have run a few simple examples like passing data from one page to another which are fine so I know the server is running ok - I think.
I have also downloaded the SQL Server 2000 Driver for JDBC and put the 3 .jar files into the lib directory of my application.
I have a test database called Orders on the same machine that I have Tomcat etc and the username and password are correct.
The top of the jsp page is as follows:
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
<%@ taglib prefix="sql" uri="http://java.sun.com/jstl/sql" %>
<sql:setDataSource var="mdb" scope="application"
                                        driver="com.microsoft.jdbc.sqlserver.SQLServerDriver"                         url="jdbc:microsoft:sqlserver://localhost/Orders:1433"
     user="username"                                   password="password" />
<sql:query var="ordersx" dataSource="${mdb}">
     select * from Orders
</sql:query>
I am not sure what I have done wrong but I am hoping it is something very obvious.
Thanks

Answer 1

I guess the first question is what version of JSTL did you get, and how did you install it?
It looks to me to be version 1.0 (compatible with JSP1.2) because of the taglib URIs.
Seeing as you jave Tomcat 5.0, which is JSP2.0 compliant you should consider using the JSTL 1.1
If you HAVE got JSTL 1.1 you should use these URIs for the taglibs:
ie http://java.sun.com/jsp/jstl/core (note the addition of jsp into the URI)
Now about this error.
The error message refers to TLD files.
It is complaining the the dataSource tag of the sql:query tag is not defined to accept expressions.
That is confusing to me, because it should. (It works on my machine)
Do you have entries in your web.xml for these taglibs? Where do they point?
Do you have a tld file for these taglibs in your web-inf directory?
If you answered yes to either of these, questions, then delete those files or remove those entries. They are unneccesary. Everything you need for JSTL should be in the jstl.jar and standard.jar files which are in your web-inf/lib directory. Entries in web.xml and tld files lying around will probably just confuse the web server, and create this error.
Hope this helps,
