Classpath for JSP
Newbie question: I'm getting an error when code in a *.jsp file tries to instantiate a class it is not found by the compiler used by Tomcat6. But the documentation says, *WebappX* - A class loader is created for each web application that is deployed in a single Tomcat 6 instance. *All unpacked classes and resources in the /WEB-INF/classes director*y of your web application archive, plus classes and resources in JAR files under the /WEB-INF/lib directory of your web application archive, are made visible to the containing web application, but to no others. I verified that the class that was not found is indeed in /WEB-INF/classes. Also, classes in *.jar files in WEB-INF/lib are found. Does anyone have any thoughts or suggestions? Thanks in advance, Reuven Koblick

Sure Chris more specifically, from the localhost.*.log
An error occurred at line: 21 in the jsp file:

Re: Classpath for JSP
Reuven,
you say the error is it is not found by the compiler used by Tomcat6, but
that is not clear from the JSP compiler output.
It says The constructor DB_Connection() is undefined, so Kris's
suggestion is right.
You could split the statement in a declaration and an assignment to prove
it:
DB_Connection dbCon;
dbCon = new DB_Connection();
Also, do you get this error only if you declare the DB_Connection() in a
JSP, or also if you declare it in another Java class ?
(the JSP compiler uses a slightly different classpath than the webapp
classloader)

Harry

Re: Classpath for JSP
Harry,
I looked at the java class files and verified there is no constructor
without arguments. That's good enough for me. You're correct that my error
description fell short of the mark. As expected, the compiler output is much
more precise than my description. That's probably why Chris Schultz asked
for more specifics.
I'm new here and can't tell everyone how much I appreciate your help and how
quick it all came. I'm new to Tomcat and JSP -- usually work with a
different framework in a different language. You all couldn't be more
helpful.
