Unable to deploy JavaFX applicaiton with external libraries in a JAR - deployment

I'm developing a JavaFX application in Eclipse. The app has external libraries, like log4j and others and runs perfectly from Eclipse. I've tried deploying it from Eclipse as a Runnable jar through the Eclipse built-in feature, and it runs well on some computers, while on others it would give me an obscure Undefined Link error. After digging around it seems JavaFX needs to be specially packaged either through an ANT script or through the javafxpackager application.
For the life of me I can't seem to deploy a runnable jar through either of those methods. Trying either of those methods, I get an Exception. Things I've tried:
Build the JavaFX application through an ANT script, below is a snippet of the relevant parts of the build script
<path id="classpath">

Compiling/generating the jar through the ant script, I get a window pop up for half a second and "Exception in Application start method" in the console, with no stack trace. I've tried runnning java with the -XX:-OmitStackTraceInFastThrow flag, but it still won't give me a stack trace.
Running through javafxpackager gives the following error:

You can deploy your application using javafxpackager. If you deploy a self contained application, the Java Runtime Environment will be bundled with your application and it will run on any machine whether the right version of Java is installed or not.
(You should have javafxpackager in your jdk directory under the bin folder.)
Look for your compiled files (.class) in your eclipse workspace folder. They should be in the bin directory.
Create a createjar folder and inside it create a classes and a out folder. Copy all of your .class files in the classes folder. Also include in the classes folder all jar needed by your application.
Now on the command line go inside the createjar directory and run this command :
"C:\path\to\jdk\jdk1.7.0_25\bin\javafxpackager.exe" -createjar -appclass package.MainClass -srcdir classes -outdir out -outfile NameOfYourJar -classpath "" -v
This should create a runnable jar in the out directory. You will need it for the next step.
Now create a deploy folder alongside the createjar folder.
Inside the deploy folder make to other directories dist and packages.
In the dist folder copy your freshly created jar from above plus all the dependencies/ressources it will need.
Go back on the command line (if you ever left it) and go in the deploy directory. Run the following command from there :
"C:\path\to\jdk\jdk1.7.0_25\bin\javafxpackager.exe" -deploy -native -outdir packages -outfile NameOfYourApp -srcdir dist -srcfiles NameOfYourJar.jar -appclass package.MainClass -name "Name of You Application" -title "Title of your application"
Once it is done it should have created all you need to deploy your app including native .exe file to run on Windows platform. This is the self contained application ! To be able to run it you need to go into bundles\NameOfYourApp\app and paste here all dependencies/ressource your app needs.
At last, double click on YourApp.exe and it should run even on machines without Java installed.

With ant files you have two main options: <fx:jar> and <fx:deploy>. The former just produces a jar that allows you to refer to your dependencies if they are in the same file as the jar. You can unpack the jar and look at the MANIFEST file produced to see how they are added to the javafx classpath.
<fx:deploy> allows you to pull in dependencies, but requires that you build a platform-specific installer. It can't be done using a jar. Apparently NetBeans allows you to create a stand-alone jar but I have not tested with that.

you do not package javafxrt.jar with your app
e(fx)clipse would have produced the ant-script for your if you use it

How to add tomcat's lib in ant build's classpath?

I needed servlet-api.jar and jsp-api.jar in my eclipse dynamic web
project.
So I went to Project -> Properties -> Targeted Runtimes -> Checked Apache Tomcat 6.0.
Now I try to build a war file using Ant as I have to deploy the war file on a unix machine.
Problem - Ant build fails (package javax.servlet does not exist, etc etc) because the jar files are not under /WEB-INF/lib/. How do I include these jar files in the classpath ? I can't hardcode it as the path is different in windows(D:\Program Files\Apache...) and unix(/usr/local/apache..).
Current classpath-
<path id="compile.classpath">
<fileset dir="${web.home}/WEB-INF/lib">
<include name="*.jar"/>
</fileset>
</path>
p.s. My Apache-Tomcat versions are different on windows(6.0.32) and unix(6.0.36)
I would check if a variable like CATALINA_HOME is set on any machine where the build might run, then you could use something like:
<path id="compile.classpath">
<fileset dir="${web.home}/WEB-INF/lib">
<include name="*.jar"/>
</fileset>
<fileset dir="${env.CATALINA_HOME}/lib">
<include name="*.jar"/>
</fileset>
</path>
Try this:
Double click on your build.xml -> Run as -> Ant build...
Choose "Classpath" and add the jars needed
I think that should be enough

Getting an error "Could not load definitions from resource net/sf/antcontrib/antcontrib.properties. It could not be found."

I am getting an error Could not load definitions from resource net/sf/antcontrib/antcontrib.properties. It could not be found. when I am trying to ant build on eclipse. So I downloaded ant-contrib-0.6.jar and kept it in my /lib location of apache ant, but it still does not resolve my issue. I have also tried by specifying the /lib location in my CLASSPATH system variable. How can I get around this error?
You can provide full path to the ant-contrib JAR explicitly using "classpath" element:
<taskdef resource="net/sf/antcontrib/antlib.xml">
<classpath>
<pathelement location="${path-to-ant-contrib}/ant-contrib-1.0b3.jar"/>
</classpath>
</taskdef>
EDIT: Link contributed by Djacomo:
http://ant-contrib.sourceforge.net/
One important thing missing from this StackOverflow page is that setting the correct ANT_HOME env var is absolutely vital and important, without this setting ant keeps telling the same error, regardless of where you copy the ant-contrib-1.0b3.jar on your file systems. This missing thing has costed me a few hours. =)
However I receive this error without eclipse, in the pure ant.
I fixed that this way:
Add the JAR to the Ant runtime classpath entries.
Window>Preferences>Ant>Runtime>Classpath
Add the JAR to either Ant Home Entries or Global Entries.
It would appear that you haven't installed the ant contrib jar into the correct lib directory. This can be difficult to do if you have several installations of ANT.
My suggestion is to install your ANT plugins into the "$HOME/.ant/lib" directory. You could go one step further and automate the process as follows:
<project name="ant-contrib-tasks" default="all">
<taskdef resource="net/sf/antcontrib/antlib.xml"/>
<target name="bootstrap">
<mkdir dir="${user.home}/.ant/lib"/>
<get dest="${user.home}/.ant/lib/ant-contrib.jar" src="http://search.maven.org/remotecontent?filepath=ant-contrib/ant-contrib/1.0b3/ant-contrib-1.0b3.jar"/>
</target>
<target name="all">
<for param="file">
<fileset dir="." includes="*.txt"/>
<sequential>
<echo message="Found file #{file}"/>
</sequential>
</for>
</target>
</project>
Use the below mentioned code in your build xml:
<path id="ant.classpath">
<pathelement location="${ant.jarPath}/ant.jar" />
<pathelement location="${ant.jarPath}/ant-contrib-0.3.jar" />
</path>
<taskdef resource="net/sf/antcontrib/antcontrib.properties">
<classpath refid="ant.classpath" />
</taskdef>
And in your build property file:
ant.jarPath=D:/antjars
And place ant.jar and ant-contrib-0.3.jar in directory:D:/antjars
Check you have read permissions for the ant-contrib jar file.
In our case after copying the file with another user it did not, giving the same error message.

Automate jar export across projects in eclipse

I have a Google Web Toolkit project for which i include a second project into the build path. This other project has a lot of my commonly used functions and classes. Building the project works fine but to avoid run time errors i have to jar the second project into the WAR folder of the GAE project.
The process of jar/exporting the second project into the first is a manual process that i do with a right click in eclipse.
Is there a way to automate the process of jar/exporting to WAR of the second project into a location on the first?
Would i do this with an ANT script?
Or is there a way this can be done within Eclipse itself.
Thanks for you help
You are in for some reading mate :)
Step 1 : Create a JAR of the first project ( Read this). In the jar task you could put as the path of your GAE's folder lib as the destfile like so :
<target name="jar">
<jar basedir="bin" destfile="../GAE_PROJECT/war/WEB-INF/lib/${project-name}.jar">
<manifest>
<attribute name="Built-By" value="${builder}" />
<attribute name="Built-On" value="${build-info.current-date}" />
<attribute name="Built-At" value="${build-info.current-time}" />
</manifest>
</jar>
</target>
Step 2 : Create the WAR for your GAE project ( Read the official documentation here ). The documentation shows how the jars in the lib are included :
<fileset dir="war/WEB-INF/lib">
<include name="**/*.jar" />
</fileset>

How can I automate compiling a large Java project?

I'm working on an automation project for my employer. We have a pool for each revision of our source code. When you download a revision, you need to create a directory structure with a bunch of third party includes to eventually build the project. I've automated this entire process up to the point of having my script (.bat) compile each particular runnable java application. There are many applications to this single project, and the directory listing looks something like this:
Proj Name
-variousincludesfolder1
-variousincludesfolder2
-variousincludesfolder3
-variousincludesfolder4
-runnableapplicationsandmoreincludes
-con.java
Right now, I'd like to do an automated compiling of con.java, but I don't know where to begin. People have suggested I try Ant, but any automated Ant file generation I get using Eclipse seems only enough to build con.java while an active project file exists. Is there anyway to automate this without using eclipse, to the point of having the batch file generate a .jar itself?
This is definitely a job for Ant. Don't rely on Eclipse-generated Ant files; read through the manual and write one yourself. (You'll likely find out that Ant does things you didn't think of doing in your build script, too.)
To be more specific, here is the documentation for the jar task.
You can define wildcard and pattern matches to include/exclude all sorts of files and folders in your build. Take a look at the Ant manual to see how things like filesets work with include and exclude filters.
Also, read the tutorial.
Here is a simple build file that looks to compile all java files and reference all jars. Place it in the top level directory:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl"
href="http://www.ibm.com/developerworks/xml/library/x-antxsl/examples/example2/ant2html.xsl"?>
<project name="Proj Name" default="build" basedir=".">
<property name="src.dir" value="${basedir}" description="base folder where the source files will be found. Typically under /src, but could be anywhere. Defaulting to root directory of the project" />
<property name="build.dir" value="build" description="Where to put build files, separate from src and resource files." />
<path id="master-classpath">
<fileset dir="${basedir}" description="looks for any jar file under the root directory">
<include name="**/*.jar" />
</fileset>
</path>
<target name="build" description="Compile all JAVA files in the project">
<javac srcdir="${src.dir}"
destdir="${build.dir}/classes"
debug="true"
deprecation="true"
verbose="false"
optimize="false"
failonerror="true">
<!--master-classpath is defined above to include any jar files in the project subdirectories(can be customized to include/exclude)-->
<classpath refid="master-classpath"/>
<!--If you want to define a pattern of files/folders to exclude from compilation...-->
<exclude name="**/realm/**"/>
</javac>
</target>
</project>

How can I automate (script) creating a war file in eclipse?

It's 5 button clicks to get eclipse to create a deployable war file for my eclipse project, I figure there's probably some eclipse command line option to do the same thing, so I can just write it into a script, but I'm not seeing it.
Use the Ant war task, set up a relevant build file and you can just hit the "external tools" button to execute it.
You could also setup a Maven build for your web project. Typing mvn package from the command line would then build the project for you.
For integration between Maven and Eclipse, see m2Eclipse and Maven Eclipse Plugin.
I cannot say anything about the WAR packaging itself, sorry.
But as I wrote in
How do I automatically export a WAR after Java build in Eclipse? : If you can describe the WAR packaging with an Ant script, you can have that Ant script being executed automatically after each change to your project. Use Project->Properties->Builders->Add->Ant Builder. Give that builder you custom Ant script and it will automatically be executed after the "normal" builders of your project.
You can even specify in the settings of the builder, if it shall only react on changes to specific files and so on.
The Ant builder is kind of a Swiss army knife for anything you want to automate in the project build without having to use the big tools like maven.
This Ant script should work for standard Dynamic Web Project structure of project:
Create Ant build.xml with replacing of two properties at begining:
<?xml version="1.0" encoding="UTF-8"?>
<project name="Deploy From Eclipse to JBoss" basedir="." default="deploy">
<!-- This replace with yours project name and JBoss location: -->
<property name="warfile" value="MyProject"/>
<property name="deploy" value="/home/honza/jboss-as-7.1.1.Final/standalone/deployments"/>
<target name="create">
<war destfile="${warfile}.war" webxml="WebContent/WEB-INF/web.xml" update="true">
<classes dir="build\classes"/>
<fileset dir="WebContent">
<exclude name="WEB-INF/web.xml"/>
</fileset>
</war>
</target>
<target name="copy">
<copy todir="${deploy}" overwrite="true">
<fileset dir=".">
<include name="${warfile}.war"/>
</fileset>
</copy>
</target>
<target name="clear">
<delete includeemptydirs="true">
<fileset dir="${deploy}" defaultexcludes="false">
<include name="${warfile}.*/**" />
</fileset>
</delete>
</target>
<target name="deploy">
<antcall target="create"/>
<antcall target="clear"/>
<antcall target="copy"/>
</target>
</project>
Now should command "ant" do WAR creation and copy them to the JBoss. JBoss automatically deploys wars which finds in deployment directory.
For automatic run after build (Project - Build) add this Buildfile here:
MyProject - Properties - New - Ant builder
