q&a to add to faq?

yo,

These questions&answers might be useful to add to the dev guide's faq:

1. regex problems with java/ant probably mean missing additional
optional/legacy ant jars. need java 1.5+ anyway to build, so not a
java version problem.
           apt-get install ant-optional

2. to fix libXp.so sharing problem get libxp-dev. i already had
libXp.so, i think, but either it wasn't in the right place or i lacked
other relevant libraries.

   http://www.debian.org/distrib/packages#search_contents
   keyword: libXp.so
   checked "packages that contain files named like this"
found libxp-dev, which worked

         apt-get insatll libxp-dev

3. you need java 1.5(5.0) to build xplanner, but should use java
1.4(2.0) when running tomcat. on debian, use
     #update-alternatives --config java
     #update-alternatives --config javac
to switch between, and/or
    export JAVA_HOME=/path/to/java/home/
seems like there should be a place in the build system and the tomcat
running system to specify which java to use or export JAVA_HOME. i
haven't looked into that.

4.  had trouble defining jdbc driver. For one, didn't work with
xplanner user because wanted access to 'mysql' database (I think). i'd
already created 'xplanner' database. resorted to using 'root' user
with plain text password, which feels very wrong to me. probably
there's a better way to do this. putting these things in the 'init'
target of build-autopatch.xml didn't seem to help (?i think)

why doesn't hibernate.connection.driver_class work? same reason as why
i'm having trouble with xplanner.root for log access when running
pre-built war?

resorted to direct declaration in build-db.xml
  <presetdef name="sql.tool">
<!--    <sql driver="${hibernate.connection.driver_class}"-->
<!--         url="${hibernate.connection.url}"-->
<!--         userid="${hibernate.connection.username}"-->
<!--         password="${hibernate.connection.password}"-->
<!--         classpathref="tools.classpath" print="true">-->
    <sql driver="com.mysql.jdbc.Driver"
         url="jdbc:mysql://127.0.0.1/mysql"
         userid="root"
         password="!!!!plaintextpassword!!!!"
         classpathref="tools.classpath" print="true">
    </sql>
  </presetdef>

5. autopatch. i'm pretty sure i had to do something to get this to
work... change a path? download something? are hibernate and migrate
two different things? oh well, I can't remember.


incidentally, the xplanner i built has the same java io error: can't
write to log problem i had earlier. ah well, thought it was worth a
try. i tried deploying the war via the html manager but it failed with
a context path problem
