This means you have a syntax error in the Java code in your JSP.

Modern JSPs should not have any Java code in them. Your best action is to refactor the Java code into a Java class and not in the JSP.

And while you're doing that, you can eliminate sql injection vulnerabilities by using a Prepared statement rather than building up a sql string.
The side effect of that will be to simplify your sql string so that you don't need to do string concatenation over multiple lines.
