ant build fails to compile

[Acharya]

Hello Hannes Ebner,
I have downloaded the source from the sourceforge svn (https://
conzilla.svn.sourceforge.net/svnroot/conzilla conzilla). The overall
ant build fails to build under tags/conzilla-2.2.6. I am using ant-1.7
with j2se version 1.6.0_06.

I have observed that the jar file is getting created under the dist
folder, but it gets deleted after the javadoc task is executed. Should
i comment the tasks following the compilation and proceed ?

Thanks
Acharya

Hi,

which target do you execute? "ant jar" should just work fine.

The dist folder shouldn't get deleted unless you call the cleanup target.

I confirmed such an error. After checkout from the repository, I
failed to run "ant" in the conzilla-2.2.6 and also "trunk" dir.
Because the dist dir has been deleted before processing "ant zip".
After adding "<mkdir dir=... />" into the "zip" target, I succeeded in
building. The environment I'm working in:
----------------------------
Platform: Ubuntu Linux 8.10
Java: sun-jdk-6 1.6.0_10
ant: 1.7.1
----------------------------
Maybe it is just a special case with the specific ant and java
version. Hope somebody can confirm it again.

Another problem is: I failed to run the application after building.
The error message is:
----------------------------
Exception in thread "main" java.lang.NoClassDefFoundError: se/kth/cid/
conzilla/app/ConzillaAPP
Caused by: java.lang.ClassNotFoundException:
se.kth.cid.conzilla.app.ConzillaAPP

Could not find the main class: se.kth.cid.conzilla.app.ConzillaAPP.
Program will exit.
----------------------------

Running conzilla using "conzilla.jnlp" is OK. :-(
But I need a native verion.

[Exaos Lee]

I forget to mention one thing: I'm using JAVA x86_64 version. The
"conzilla.jnlp" cannot be started using 64-bit javaws, but OK with 32-
bit javaws.

I just ran the target with the very same OS, Java and Ant versions, and
"ant zip" works without any problems. The cleanup gets called before the
compilation, thereafter the whole structure, including the "dist"
directory is created. That's where you should find the zip file.

Be careful about upper/lower case. The class is called ConzillaApp (not
APP).

HTH,
Hannes

What's the problem with javaws on 64-bit? Could you send the error
messages or console output?

Thanks,

$ javaws conzilla.jnlp
netx: Spec version not supported (supports 1.0)

[Exaos Lee]

Both "ConzillaAPP" and "ConzillaApp" cannot work. The same error. :-(

How does your classpath look like?

Which Java are you running? Version, vendor, etc.
Currently the JNLP file is made according to JNLP spec version 1.5.

----------------------------
Platform: Ubuntu Linux 8.10, x86_64

Java: sun-jdk-6 1.6.0_10
ant: 1.7.1
----------------------------

Cannot build on Ubuntu Linux 8.10 x86/x86_64 both.
Java: sun-java6-jdk 1.6.0_10
ant: 1.7.1
Classpath: the system default setting, no customization

The jnlp file cannot be launched by Java 1.6.0 amd64 version, but can
be launched by x86 version. On my AMD64 system, it works fine with
ia32-sun-java6-jre.

Today, I tried to build conzilla 2.2.6 from SVN on Debian Linux 5.0
amd64 with sun-java6-jdk, still failed with the same error as above!
(Default system setting) :-(
Though I can use Conzilla with javaws (IA32 version), I cannot run it
on another platform without networking. I will try again if I have
spare time.

OOPS! I tried to install sun-java5-jdk, Failed to build again!

OS: Ubuntu Linux 8.10 x86
Java: sun-java5-jdk, java 1.5.0_16
---------------------
% javac -version
javac 1.5.0_16
---------------------
ant:
--------------
% ant -version
Apache Ant version 1.7.1 compiled on October 3 2008

After executing "ant", I got the following Error:
----------------------
zip:

After removing the dependence on "cleanup" from "zip", builing is OK!
But still failed to execute:

=================================

I hope my problem is described clearly enough, the OS platform, java
version, ant version, building process, classpath, etc.
Another question is: I didn't get the "Conzilla-formlets.jar" in the
"dist" dir after successful build with a little modification with
"build.xml" by removing the dependence of "cleanup" from "zip" target.

Which ant target are you actually executing? If I run "ant zip" all
directories which don't exist are created, including the "dist" directory.

I tried to, but I didn't succeed yet with reproducing the problems you
are facing.

This file hasn't been updated for quite some time because the webstart
version is the only supported method of deployment right now. If you add
all files in the lib directory to the classpath in the shell script it
should work.

I will try to reproduce this problem in a 64-bit Ubuntu VM.

I just type "ant", which means "ant all".
The commands "ant jar" and "ant scripts" are executed OK, but failed
to run the script and "Conzilla.jar".
Could anybody upload a compiled distribution here? I don't want to
build again. :-(

[Exaos Lee]

I just setup the CLASSPATH, and run directly in the "classes" path, It
seems OK. It might be the problem of archiving the ".jar" file. So,
until now, two problems are on my platform:
1. "ant jar" cannot generate an available "Conzilla.jar". I cannot
using the generated ".jar".
2. "ant zip" cannot generate the "zip" file directory.
