Latest in the ongoing story of why even the simple things take much longer than they should: I’m working on an app where the menus generate PrettyFaces bookmarkable URLs. However, when I jump to the target page, then click on a commandLink, the secondary target page won’t post properly. When ( more… )
The MyFaces extensions validator package looks like someday it will make life a lot more pleasant when designing JSF backing beans. Instead of cluttering up the markup with cumbersome extra XML, the MyFaces Extensions Validator allows you to annotation the backing bean properties. It even adopts the applicable annotations (such ( more… )
There are reports that messages of this sort were due to bugs in one or more Hibernate releases. But this is also a legitimate error. I wasted a lot of time before it hit me. The original code was: @SuppressWarnings(“unchecked”) public List<State> getStatesForCountry(String countryID) { final String SQLCOMMAND = “SELECT ( more… )
I’ve always recommended against this. For one thing, a WAR is a ZIP file and Java has no builtin support for updating ZIP files. A lot of people abuse the fact that many JEE servers unpack (explode) WARs into a directory such as Tomcat’s webapps directory. They then proceed to ( more… )
SF itself is fairly straightforward. Getting it functional in an appserver is another matter. Originally, I used MyFaces and Tomahawk. More recently, I’ve replaced MyFaces with the Sun JSF Reference Implementation (RI). Tomahawk, although a MyFaces library works just fine with the RI. The JSF-impl jar is part of the ( more… )
Oh, what a tangled web we weave… In theory, using JPA and Spring is supposed to make magical things happen that will make me more productive and allow me to accomplish wonderful things. Someday. At the moment, I gain tons of productivity only to waste it when deployment time comes ( more… )
One of my greatest peeves in working with Java in the Enterprise is the fact that everyone+dog seems to think they can do a better job on application security than the Java architects. OK, so there’s some really awful stuff that’s part of the Java standards, but nevertheless, rolling your ( more… )
disclaimer: I’m about to show my age. My first “IDE” was an IBM 029 keypunch machine. I keyed programs in FORTRAN, COBOL, Assembler and PL/1. When I messed up, I threw away the defective cards and punched new ones. After waiting in line for a free keypunch machine. Over the ( more… )
I developed my Technology Sandbox app using OpenJPA under Tomcat6. Since JBoss 4.2 has its own persistency mechanisms (EJB3 and Hibernate), it looked like some changes might be required to port it. It turns out that very little needed to be done. The most important thing is to get a ( more… )
You can insert graphics into an OpenOffice Writer document – or any of a number of other document editing programs. It’s generally a simple “Insert picture/from file…” menu option. Getting it not to look like garbage is the hard part. Most images are bitmaps and scaling bitmaps usually results in ( more… )
