No. PDF documents have a complex structure and there are no classes for that in the Java core library.
Maybe in the future java 5 is also available.
Java 6 is even available and Java 7 is on its way, but there is still no PDF support.
Frankly, if you want to create PDF documents, there is one obvious choice: iText. See also
