Cannot compile ("variable interfaces")

Hi All,

Since yesterday night i'm trying to use Middlegen, but there is something i'm missing. Middlegen opens the GUI window, I click on "Generate" and it seems to work. After closing the window, the rest of the process begin done, but stops when it tries to compile Struts files, hanging with errors like this:

    [javac] symbol  : variable MIN_VALUE
    [javac] location: class java.lang.Boolean
    [javac]       if(getStatus() == java.lang.Boolean.MIN_VALUE) {
    [javac]                                          ^
    [javac] /opt/downloads/middlegen-2.0-b1/contatos/build/gen-src/contatos/web/struts/TelefoneForm.java:32: cannot resolve symbol

With the example "airline", everything is done successfully, so, i guess that the problem is on my build.xml. 
I've uploaded the build.xml and build.properties to www.partenon.com.br/contatos/, to someone verify if its all ok.

System:
Linux Slackware 9.0 (Kernel 2.4.21)
Middlegen on /opt/downloads/middlegen-2.0-b1
PostgreSQL 7.3.4
JBoss 3.2.1 w/ Tomcat.

TIA,
juca
