As you can see, there is no semicolon in line 1 and the error message
is showing the code exactly as it is in the tomcat/webapps/... directory.



Can anyone help explain why a semi-colon error would be reported in the error message when
it does not exist in the source code?

The ';' will be in the generated Java source code. Tomcat uses "Java Debugging Support for Other Languages" to map errors in the Java source to the associated line in the JSP.

Compilation errors often don't map very well.

You want to look at the generated source for the JSP (it will be in the work directory) and see if you can figure out what is triggering the error.

Alternatively, post the source for the simplest standalone JSP that triggers the issue and the people here can try and reproduce it.
