Hi,

I'm working on Mac OS X. I ran the git clone command to download the
PocketChangeApp, changed to the directory, and tried mvn jetty:run.
Towards the end of the voluminous diagnostic output I got a copule of
Java null pointer exceptions with lengthy stack traces and the error:

org.postgresql.util.PSQLException: Connection refused. Check that the
hostname and port are correct and that the postmaster is accepting
TCP/IP connections.
[...]
ERROR - Failed to Boot
java.lang.NullPointerException: Looking for Connection Identifier
ConnectionIdentifier(lift) but failed to find either a JNDI data
source with the name lift or a lift connection manager with the
correct name

The web server did finally come up, but when I load the page in
firefox I see "No Navigation Defined." in the space where the
navigation links should be.

Do I need to explicitly install or configure postgresqll or something
to get this example running?

Additionally, I noticed a couple of broken links in the current PDF:


Somewhat ironically (page 5, section 1.2):
1. The first place to look is the Wiki at
http://liftweb.net/index.php/Main_Page.

is no longer a valid link. ;-)

Also, the URL first footnote in chapter 2:

1 http://wiki.liftweb.net/index.php?title=Lift_View_First. [...]

is also invalid.

Thanks for the feedback. The PocketChange app is designed to run against a PostgreSQL instance currently. I'll have some time later this week to work on it and I'll change it so that if PostgreSQL isn't available it will fall back to using Derby. I'm guessing that the other issues are because Boot failed with the DB setup part way.

OK, thanks. Seems fine to me to require PostgreSQL, but please just
mention it in the pre-requisites in section 1.3. Would be great to
give the verison of PostgreSQL you use for development / testing of
the examples, pointers to what packages to install for the 3 major
platforms, and any other information one might need on configuration /
setup of the db instance needed to run the examples.

Hello,

I'm following "the book" to get up and running into lift.
I have, however, some questions:

For forms:

In page 47 you have :

<lift:Ledger.add form=POST>

With me form=POST does not work (it's terrible to get into the root cause with that stack trace :) )

It works with form="post"

It's something I'm missing? Why not using quotes in the book?

In page 48, first code:

bind(entry,..

Also, entry without quotes, isn't working. The same applies with the rest of the fields that aren't working without quotes "". Again, is something I'm missing?

thank you

You're not missing anything, there are a few places where quotes are
getting stripped.
Looks like we missed a couple.

In the interest of keeping the book simple, I just changed it to use Derby. I commented out the postgresql stuff so that it would be easy to add it back in, but setting up your own DB server is outside the scope of the book and I don't want it to be an issue.

Cheers,

Derek

Makes sense, good idea.
