Ant 1.7.0Beta3 released
Hi,
Ant 1.7.0Beta3 has just been released. This will be visible on our
website in one hour at most.
A number of bugs have been corrected since Ant 1.7.0Beta2. One important
change or correction is that the processing of references is now
deferred to the time of target execution, not done when the build files
are parsed.
Regards,
Antoine

Re: How to resolve a NullPointerException
Posted by Antoine Levy-Lambert <an...@gmx.de>.
Hello,
how do you run this programatically ?
one common source of null pointer exceptions in Ant API use is to forget to set a project reference on task objects or datatypes. The null pointer exception happens then as soon as the task or the datatype tries to log something.
if you have a NPE when using command line Ant, run
ant -verbose
(-verbose is a command line argument)
this will give you a stack trace.
Regards,
Antoine

How to resolve a NullPointerException
Posted by tharanga wijethilake <th...@ee.oulu.fi>.
Hi all,
I am tring to run this Ant file using a java program.
When I run this using "Ant run" option provided in eclipse it runs with out any trouble.
<project name="bundleRunner" default="submit_a_bundle" basedir=".">
<property name="ant.classpath" location="lib"/>
<taskdef name="smfbd.submitJarBundle" classname="com.ibm.ive.eccomm.bde.ui.tooling.ant.SubmitJarBundle">
<classpath>
<fileset dir="lib">
<include name="${ant.classpath}/smfbdTasks.jar"/>
<include name="${ant.classpath}/bde.jar"/>
</fileset>
</classpath>
</taskdef>
<target name="submit_a_bundle">
<smfbd.submitJarBundle bundlepath="/HelloWorld" replace="true">
<bundleserver host="localhost" user="Admin" password="Admin" port="8080" webapp="/smf"/>
</smfbd.submitJarBundle>
</target>
</project>
but when I try to run prgrammtically it gives a null pointer. Please Could someone tell me how am i supose to find from where the exception throws.
submit_a_bundle:
BUILD FAILED
C:\Documents and Settings\tharanga\My Documents\IBM\wssitedev51\workspace\AntRunner\build.xml:12: java.lang.NullPointerException
Total time: 2 seconds
It is line 12 but is it the "bundlepath" or is it because of the related class file for smfbd task is missing. Thank you very much.

Its just laziness. We have an implicit trust in the quality of other
open source products, or, more to the point, know that SVN_HEAD is where
bug fixes go. Its just Ant's use of XML is limited to DTD-free,
schema-free, namespace aware XML. We dont see the main problems that you
may if you go near the PVSI, and dont use bleeding edge APIs that dont
work in older JVM versions. We also suspect that people running Ant in
IDEs or embedded use may not even use Xerces, so try not to hard-code
dependence on Xerces, either.

Ah, yes. I should have said JAXP 1.3 Schema Validation API. The thing
thats returned by SchemaFactory.newSchema()[1]
But whats the reason to sticking to Xerces 2.6.2 ? Anything more than
"Don't fix what not broken" ?

As of 30 seconds ago, it distributes v 2.8.1. Version 2.6.2 does do XSD
validation BTW, which is why Ant1.7 has a <schemavalidate> task.

Ah, joy, the java endorsed dirs mechanism. If that is causing a problem
for you, then the version of xml-apis in ant/lib is moot; you need to
get a better version into an endorsed directory.

Cant do that, because in the Maven repositories
-xml-apis is at 2.6.0
-xerces is at 2.8.1, and has a dependency on xml-apis 1.3.03.
We keep it under SCM, as it is the only thing needed at boot time.
Historically it was also there because there was no bundled Java parser,
and when one did come, it was only Crimson. But for the 1.5+ world, we
could think about doing a no-parser distro. Not for 1.7, there will be
too many surprises related to manifests. Something to think of.

Is there any reason why ANT 1.7 still distributes Xerces 2.6.2 in its
lib [1] ? While the current release version of Xerces is 2.8 with
support for DOM Level 3, Schema Validation, Not to mention the bug fixes.
Last time i tried to compile code that uses the DOM Level 3 API, the
xml-apis.jar in ant/lib got in the way and i had to use
java.endorsed.dirs mechanism in ANT_OPTS.

we had a skype teleconf with them on this topic a while back, and that's
effectively what is going to happen. ant's <junit> is constrained to be
backwards compatible and run on Java1.2, 1.3+, whereas junit's own task
would be able to be java5 only, and in perfect sync with junit releases.
They would of course have to deal with changes across ant's versions.
However, the junit team lack the time and skills to do ant tasks. So it
will come to us -ant users and developers to write (and possibly
maintain) the task. We need to not only give it to them, we need to show
them how to maintain it.
FYI, I have been doing some stuff with hosting junit tests under
smartfrog, our deployment framework:
http://video.google.co.uk/videosearch?q=smartfrog
http://smartfrog.org/presentations/distributed_testing_with_smartfrog_slides.pdf
There we can run tests in one process, and feed the results to another
by way of java RMI; I have a serialized representation of test results
that I can feed to another process. Having something like that inside
<junit> would let us run the logging inside Ant, while the tests would
be in their own process. I also have a different format for test
results, one that streams out instead of buffers until the end.
I'd like the same stuff in a <junit4> task, ideally. In fact, ideally,
I'd like the classes representing junit-results-on-the-wire to be in
junit.jar, rather than my code.

To add another thing to consider, perhaps the <junit/> task should be an
externally owned task, similarly to <testng/>, rather than something
that is part of ANT, even as an optional task. Then the JUnit4 guys, or
whoever owns the accompanying task, would be responsible for providing
an updated version.

1. we go through a rigorous beta test phase as it is the best way of
making sure you havent broken anything. Even so, we know that lots of
people will not touch it until version 1.7.0 ships, and there will be a
flurry of bugreps, usually related to odd system configurations

2. That's a shame. I've been using Luntbuild and it binds quite nicely
to Ant1.7

Why does it take so long to finish the next version of Ant?
Because of the delay of the next Ant version, the next version of Cruise Control is delayed too.
At least you should have released quickly a Ant version with built in support for JUnit 4.
