Re: One Build.xml

U don't need to build ear every time to test application
 
In your application.xml write
 
   <module>
      <web>
         <web-uri>SOME_DIR-web</web-uri>
         <context-root>/</context-root>
      </web>
   </module>
so you will get:
 
APPLICATION-DIR/
  META-INF/
     Application.xml
  SOME_DIR-web/
  your_ejb_here
 
I use Ant for ejb building, but ANT have a bug in ejbjar task
i've made a little patch to "Ant.src/src/main/org/apache/tools/ant/taskdefs/optional/ejb/DescriptorHandler.java "
 
            if (!className.startsWith("java.lang")) {
                // Translate periods into path separators, add .class to the
                // name, create the File object and add it to the Hashtable.
// Parf's patch here
//                className = className.replace('.', File.separatorChar);
                className = className.replace('.', '/');

                className += ".class";
 
So your build.xml will look like this one:
 
  <target name="mkbn" depends="library">
     <ejbjar descriptordir="${src}"
              srcdir="${build}"
              destdir="${ejb}"
              basenameterminator="."
              genericjarsuffix=".jar"
              flatdestdir="true"
              >
       <include name="**/*.ejb-jar.xml"/>
     </ejbjar>
     <antcall target="app"/>
 </target>
  <target name="app" description="Rebuild Application.xml" >
    <exec dir="${src}/JG" executable="perl">
       <arg value="Make_Application_Xml.pl"/>
    </exec>
  </target>
Make_Application_Xml.pl - simple perl script for auto generating Application.xml:
my $jars;
for(`ls /e-mall/*.jar`) {
 s/.*\///; chomp; $jars.="  <module><ejb>$_</ejb></module>\n" ;
}
open F,">/e-mall/META-INF/application.xml";
print F <<EOF;
<?xml version="1.0"?>
<!DOCTYPE application PUBLIC "-//Sun Microsystems, Inc.//DTD J2EE Application 1.2//EN" "http://java.sun.com/j2ee/dtds/application_1_2.dtd">
<application>
   <display-name>Axwell Portal</display-name>
$jars
   <module>
      <web>
         <web-uri>e-mall-web</web-uri>
         <context-root>/</context-root>
      </web>
   </module>
</application>
EOF
close F;
Ant will search for all *.ejb-jar.xml's and make them (only home,remote & bean libs)
To include other files make a application side library:
something like this:
  <target name="mall-ejblib" depends="ejblib_init" >
    <jar jarfile="${ejb}/ejblib-mall.jar" basedir="${build}">
       <include name="META-INF/ejb-jar.xml" />
       <!-- lookup -->
       <include name="unipoint/ejb/lookup/AlexEJBLookup.class" />
         ......
    </jar>
  </target>
 
Btw there is another bug in Parser.jar that comes with Ant,
when it locates string like this in xml declaration it tryes to get dtd from given location
<!DOCTYPE ejb-jar PUBLIC '-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 1.1//EN' 'http://java.sun.com/j2ee/dtds/ejb-jar_1_1.dtd'>
I've decompiled and patched this too. - Speed increase more than 20x.
 
Now it takes only 5 sec for me to compile, build and install any beans/servlets with orion & Ant.
 
BTW: if u like to build a ear add a simple jar task for war and jar task for ejb library

Subject: One Build.xml

Hi Guys
Has any of Orion gurus found a way to use tha same build.xml that more or less can be adapted to create diff ejb.ear
if it is possible  it will save loads of time
