hi all

Today I attempted to upgrade from tomcat 4.1.10 to 4.1.12LE which also
involved moving from jdk1.3 to jdk1.4. Before porting across my application
code, I thought I'd give the examples application a whirl, to sanity check
the installation. While the servlets work ok, I have compiling the JSPs
down into servlets. More specifically, jasper barfs with the following
stack trace:


org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: -1 in the jsp file: null

Generated servlet error:
Detected Java version: 1.4 in: c:\usr\local\lib\jdk1.4.1\jre

Setting the Jasper logging to default, I have found the following in
$CATALINA_HOME/logs/localhost_log.2002-10-22.txt:

On the line where the error is reported above , the absolute path to the
java code is wrong, i.e. "dates\/date_jsp.java" should be
"dates\date_jsp.java", shouldn't it???

I have been searching the archives all afternoon and am aware of bug 10036
which is to do with the JDK1.4 compiler now rejects import statements that
import from an unnamed namespace. I dont think this is related....

As I see it, there must be many people who have got the JSPs in the
Examples application compiling before now, so expect that there is a small
config error somewhere on my part. (See my config details below)

If you can spot the bug, i'll buy you a beer next time you're in London!
TIA

Nigel
