tjava 0.4

This is the CPAN module Template::Plugin::Java. It is designed to assist
in the generation of Java code using the Template toolkit. To this end,
it offers generation of Java beans from XML description files, and from
table schemas via Template::Plugin::JavaSQL.

THIS IS AN INTERMEDIATE RELEASE
-------------------------------

I was annoyed with how long all the necessary changes were taken, so this is
already MUCH more useful than 0.3. There is no dependency on any non-existant
parser any more. Beans parse themselves out of SAX, quickly, recursively. The
toString() method of all beans now replaces any need for an xmlEncode(). The
DBClass template works much better. Etc. This thing is actually more or less
usable now.

I hope 0.5 to be more documented and cleaner over all.

QUICKSTART
----------

Make an .xml file I will use the one in the Template::Plugin::Java
manpage:

<aBean> 
	<foo>10</foo>
	<bar>String</bar>
	<container>
		<baz>20</baz>
	</container>
</aBean>

called ABean.xml.

For a database generated bean, it'd look something like this:

<aBean>
        <java:
		template="DBClass"/>
        <sql:
                table="tin_can"/>
</aBean>

The SQL context can also be:

	<sql:
		query="select * ... (complex select expression here)"/>

Then, make sure TEMPLATEPATH is set correctly, the default templates are
installed into ${PREFIX}/share/tjava, so usually you will want to have:

export TEMPLATEPATH=/usr/local/share/tjava

tjava ABean.xml
jikes ABean.java # or javac, whatever

Look at the source for ABean.java to see how to use it. The database clases
support basically, setX(), find() (based on what is set), store() (current row
update, or insert new row if not on something from find()); and remove() to
delete the row on which the cursor is currently. Most importantly, after
find() you MUST call next() to advance the cursor to the next row, and
thereafter until next() returns a false value. Example usage:

Employee e = new Employee(db_connection);
e.setFirstName("Rafael");
e.find(); // select * from employee where first_name = 'Rafael';
while (e.next()) {
	System.out.println(e);	// Print them all out.
}

More extensive documentation is forthcoming.
