I need to see the servlet (.java) code of a simple JSP code like this: <% out.println("Testing."); %> I installed Ant 1.5 and Tomcat 4.1.12. build.xml file for Ant is like this: simple JSP compile destdir="." verbose="9" classpath="C: empTomcat-4.1.12commonlib"> that common/lib includes jasper-runtime.jar and jasper-compiler.jar. and when trying to compile: C: emp est>ant Buildfile: build.xml compile: [jspc] Compiling 1 source fileC: emp est More>>

I need to see the servlet (.java) code of a simple JSP code like this:

			

			

			

			

			<% out.println("Testing."); %>

I installed Ant 1.5 and Tomcat 4.1.12.

build.xml file for Ant is like this:

			

			

			

			simple JSP compile
			

			

			

			

			

			destdir="."
			

			verbose="9"
			

			classpath="C: empTomcat-4.1.12commonlib">

that common/lib includes jasper-runtime.jar and jasper-compiler.jar.

and when trying to compile:

			

			C: emp est>ant
			

			Buildfile: build.xml
			

			

			compile:
			

			[jspc] Compiling 1 source fileC: emp est
			

			[jasperc] java.lang.NoClassDefFoundError: org/apache/jasper/JspC
			

			[jasperc] Exception in thread "main"
			

			

			BUILD FAILED
			

			file:C:/temp/test/build.xml:10: Java returned: 1
			

			

			Total time: 3 seconds
			

			C: emp est>

Any ideas?

Is there any other way to compile single or few JSP pages, so that I would see the servlet code? I'm using JBuilder6 and as far as I know its not possible to see servlet code in JBuilder.

Try setting your classpath as follows:

classpath="[tomcat-root]/common/lib/jasper-compiler.jar:[tomcat-root]/common/lib/jasper-runtime.jar:[tomcat-root]/common/lib/servlet.jar:[ant-root]/lib/ant.jar"

You're probably going to have to switch / with .

your app or web server compile JSPs. you cannot use ant to compile JSP since JSP is not a java file and you cannot compile it as you would compile a normal java file using javac or jikes or whatever compiler you are using. in addition, each web/app server does something a little bit different when compiling JSP into servlets so your servlet code generated from JSPs will slightly vary from one server to next. I am not aware of any compilers for JSPs that you can use in your ant scripts. your best bet is to just start your web/app server and access the JSP and then look at the generated code. A bit tedious but doable through ant.
