thanks a lot david, just one last query (if i a mnot irritating you),
when you say that tomcat has its "own" compiler, then you mean a compiler
other than jasper ..right ??

as you said, tomcat has a java compiler for compiling jsp -> servlets
"called" jasper.
this is what i read in the wikipedia :
"Jasper parses JSP files to compile them into Java code as servlets"
by that definition, is it right to call jasper a java compiler ?? it is
just a jsp parser, and it cannot work for normal java programs !!
I'm not a great expert in how tomcat's compilation of jsps works, but I
do know jsp files are compiled first to .java source code and then
further compiled to .class files (servlets to be specific). You can see
evidence of this in tomcat's work directory.
if i understand you, you are saying that we need a JVM (and not a java
compiler) as a dependency (or a prerequisite for installing tomcat).
this means that tomcat HAS its own compiler, and it only needs a jvm
provided "externally" ,right??
This is correct.

you further say : "BTW: java is the JVM, javac is the compiler."

Tomcat does have a java compiler (jasper) to compile jsp pages to
servlets, but it also needs a JVM (java). Setting CLASSPATH is a big
no-no. Put any required jars your webapp might need in the proper
place. If you use tomcat's internal pooling for db connections, that
means putting driver jar files in tomcat's lib directory.

hi, i am pretty new to tomcat. currently i have tomcat6 on
ubuntu-linux.
i have pursued some books on tomcat , but they cant help me getting
some concepts, they simply point to "using tomcat"
here is one of my doubts i got during database connection..
does tomcat have its own java compiler ?
PROOF THAT TC HAS A SEPERATE JAVA COMPILER
when i normally connect my simple jdbc program (not a web
application), i have to set the CLASSPATH variable for locating the
connector/J jar file.
but when i am running a jsp in my web-app, which uses jdbc, CLASSPATH
doesnt help..i have to explicitly place the library in the web-app's
lib or the common/lib.
PROOF THAT TC DOES NOT HAVE A SEPERATE JAVA COMPILER -
while installing tomcat, java was demanded as a prerequisite
...meaning to say that tomcat depends on an external java compiler
i hope i am not asking a "dummys" question,as i am new to java too !!
but i will be happy if you people can answer me and/or point me to a
nice tutorial to know "how tomcat works" rather than "how to work on
tomcat".
thanks all !!
