Ant compileWebapp

Question

Anyone know ant well enough to tell me what is wrong w/ my compile? The DVDItem.java compiles w/ javac DVDItem.java but not w/ ant compileWebapp. I'm new to ant so please your audience is a newbie. See below:
staticWebapp:
compileWebapp:
[javac] Compiling 2 source files to C:\Program Files\Apache Software Foundation\Tomcat 5.0\webapps\dvd\WEB-INF\classes
[javac] C:\Documents and Settings\jcwaters\My Documents\Personal\programming\java\SunWLC\labs\SL314\exercises\project\src\model\DVDItem.java:3: cannot access java.lang.Object
[javac] bad class file: C:\Program Files\Java\jdk1.5.0_06\jre\lib\rt.jar(java/lang/Object.class)
[javac] class file has wrong version 49.0, should be 47.0
[javac] Please remove or make sure it appears in the correct subdirectory of the classpath.
[javac] public class DVDItem implements java.io.Serializable {
[javac] ^
[javac] 1 error
BUILD FAILED

Here is the build.xml that came w/ the exercise. Where do I put the new attribute? Again, first time I've used ant. I know both tomcat and ant are from apache. Tomcat is a webserver.
