javadoc doesn't generate html files if the source directory doesn't match packag

I have a case where the source directory structure doesn't
match the final package structure. I am finding the
javadoc doesn't generate the html files from the comments
lines in the *.java files. I am using the latest
jdk-beta2-solaris2.

My source directory structure is as follows :

                  /export/home/joe
                        |
             --------------------------------------
            | | |
          classes src doc
                            |
                      ---------------------------
                     | | |
                   demo1 demo2 demo3
                     | | |
              demo1_client.java *.java *.java


The *.java has the line :

package sunw.demo;

The following is the javadoc command:

cd /export/home/joe

/opt/jdk-beta2-solaris2/java/bin/javadoc -d "./doc" -classpath ".:./classes:./src/demo1:/src/demo2:/src/demo3:/opt/jdk-beta2-solaris2/java/lib/classes.zip" sunw.demo

Loading source files for sunw.demo
Generating packages.html
Generating index
Generating tree


Under the doc directory I find the following files are generated :

AllNames.html
Package-sunw.demo.html
packages.html
tree.html

But no sunw.demo*.html files.
