I think I may not have articulated my problem correctly. I am using WAS 8.5 JDK 1.7 set-up as general build set-up for my ANT, but for this particular application, it uses separate JAXB1.0 jars on JAXB 1.0 generated classes. It includes 4 jaxb jars in the web-inf/lib - so I basically need to go back to 1.0 version in my javac step for the application.
So, if I use the endorsed jvm property for a backward version, will it work and do I have copy just the jaxb-api.jar to that directory? The web-inf/lib contains jaxb-api.jar, jaxb-impl.jar, jaxb-xjc.jar and jaxb-libs.jar and some other jars used by the application. -----Original Message----- From: Martin Gainty [mailto:mgai...@hotmail.com] Sent: Monday, September 15, 2014 5:39 PM To: Ant Users List Subject: RE: Need help with ANT javac classpath > From: webservices_developm...@csx.com > To: user@ant.apache.org > Subject: RE: Need help with ANT javac classpath > Date: Mon, 15 Sep 2014 16:06:55 +0000 > > Thanks. > > This is a common build script that we have, so I didn't add fork for the > javac task - as it would affect other builds as well, that use the latest > java version and follow the default build. > > If it is not possible at all to incorporate something in the common build, I > will take a look at separating this one out, but want to avoid it, if I can. > > I had looked at the endorsed directory, but I got the impression that it is > to be used when you want to use a later version, not earlier.

This essentially makes your JRE to "JRE 6 + JAXB 2.x". This won't affect any other applications that use this JRE, and it's easy. On the other hand, in various scenarios you may not be able to alter the JRE. Use the system property java.endorsed.dirs when you launch your application, and have it point to the directory that contains the 2.1/2.2 jaxb-api.jar. This allows you use use JAXB 2.1/2.2 without modifying the JRE. Make sure not to include any other JAXB RI jar files (such as jsr173-api.jar or jaxb-impl.jar.) Implement a custom ClassLoader and block delegation to javax.xml.bind package, so that code running inside this class loader will load the JAXB API from elsewhere. This is a very advanced approach.
