Is it possible to export the talend job as one jar only (inclusive of all its dependencies)? Because currently, the exported zip file has the dependencies outside.
Thanks in advance
I never found a way to achieve the one single jar inclusive of dependencies output via the Talend Open Studio (Community Edition). The workaround is to create a Java Application, add the libraries and the job jars into it, then package that java application as one fat jar.
You can build the job.
Repository > jobs > your job > right click > build job

i am new to talend ESB so lately I started learning and i developed a job that returns a document using REST api and everything works fine, my question here is that i exported the job as a osgi bundle jar and i want to run it outside talend.Any help would be appreciated thank you.
You need an OSGI container but you can build a standalone package.
In the Deployment Tab, select MicroService For ESB
Then Build Job with a build type "Microservice" and check "Export as
ZIP"
The ZIP will contain script files ( .bat, .ps1 or .sh) to start your Talend program from the command line.
I have a Maven project in SVN with trunk\Config\TestProjConfig folder having all the XML configuration files and all Java code is in trunk\JavaSource\TestProj. When I check out to my local Eclipse there are 2 projects created one for TestProjConfig and one for TestProj.
How do I test this project? Do I have to edit the build path to make a connection between the two projects? Do I have to write a main class which accesses the AppContext file to invoke the Spring injections?
Note:I have the m2eclipse plugin in Eclipse.
I don't understand why you separated XML configuration from Java sources. It could be a good practice only if you want to reuse your conf in other project, but in this case, I'm not sure that's suitable.
Solution 1
Move all your xml config into JavaSource\TestProj\src\main\resources
If you really don't have to share your configuration or don't have any legacy / corporate / mysterious reason, you should not separate them.
Solution 2
If you REALLY want to separate them, put them in a zip with an assembly, and add a dependency from TestProj to TestProjConfig.
Here an example : Maven - Depend on assembled zip
My dream when using the Eclipse IDE is to have my .java files obfuscated and exported to a .jar file automatically.
At the moment, I use two applications to repetitively perform my obfuscation and jar exportation, and it really is a pain!!!
If I'm correct, the only way to do this is to create my own Ant Task - if this is the case, may you guide me step by step on how to create this Ant Task?
Thank you gurus, I will soon be able to rest my hands for just that little bit longer!
Excelsior Jet has a Eclipse plugin.
Proguard has ant tasks.
I am developing JSR 268 compliant portlet and utility with eclipse.
Now, the utility is designed to be a separate JAR from the portlet itself.
Does anyone now how to write an ant build.xml that will
1. Compile and JAR my utility class
2. Move the JAR to the ./lib folder of the portlet
3. Compile and maybe even delpoy the portlet to a tomcat running on localhost?
My biggest problem right now are the build-time dependencies. I dont want to hardcode all the folders as I share this project with two other developers which are on another platform.
Is it possible to reuse the buildpath from eclipse?
Thank you in advance,
Felipe
Does this wizard help
Rigth-click on project -> Export ... -> Ant buildfiles.
?
Though you probably have figured something out by now, for future references I would suggest taking a look at Eclipse's ability to use Ant files as project builders.
An advantage of this is, that will happen automatically as you build and since you only pack and copy the jar file, you don't have to worry about changes in e.g. the class paths, as you would in the two previous answers
Create a ant file that jar the utility project. Follow: [1]
Add it as a ant-builder to your utility project as described in [1]
Now Eclipse will automatically generate the jar file every time you build.
Extend the ant script to also copy to jar file to the lib dir.
Eclipse have ant task to convert workspace/project relative paths to
normal file paths. See [2]. Note that for those tasks to work, you must select ''Run is the same JRE as the workspace'' under the ''JRE'' tab when configuring the ant builder
In order to ensure your utility is build first add a project reference from your portlet to your utility project right click > properties > project references
When you build the following will now happen:
You utility project will build first, because of the project reference
The ant-builder will pack the jar, and copy it to the lib folder.
You portlet project will build using the new jar.

For 1. Just use the and Ant tasks
For 2. Is it on a remote server? How do you get it there? Windows share?
For 3. Set up the Tomcat manager and then use Tomcat's deploy/undeploy Ant tasks:
http://blog.techstacks.com/2009/05/tomcat-management-setting-up-tomcat.html
<taskdef name="deploy" classname="org.apache.catalina.ant.DeployTask" />
<taskdef name="undeploy" classname="org.apache.catalina.ant.UndeployTask" />
If you want to avoid hard-coding paths, try to use relative paths. Where are you dependencies right now? What do you feel you may have to specify an absolute path for?
In Eclipse,
Goto Window->preference->Ant->Runtime->Classpath->ant Home
Then add what are the thing u need to add,atlast click ok button to create ant file.
I'm doing the build automation for a java app with ant. This is a client-server app which has many projects in eclipse. I would like to create a jar file for the client and one for the server, but since the class dependencies are all over the projects (in eclipse)... I had the idea to use a tool to automate the search for dependencies. I've been looking at GenJar witch is almost all I need but it's not been updated in a while. So I would like to know if there are any other tools like this one, maybe Maven?
You may also try FatJar
It kind of sounds like what you really want is a WAR file.
Personally I would go with Ant + Apache Ivy. Each project has its own build.xml file and publishes to a central Ivy repository. Other projects will simply download these dependencies as needed.
The advantage of having an Ant based build process is that you can very easily automate it and use a continuous server to build the entire product after each check-in.
