Custom Routines in multiple Projects

Anonymous — Thu, 02 Feb 2017 12:17:28 GMT

Hello community!
We've been using Talend for a while, creating Jobs in one project. We also have a set of routines that we use in all our jobs.

Now we are creating new jobs in a different project, because the scope is different but we need the same routines. So we import the routines into the new project.

I think this is not a good solution, since we have now duplicated the code, and maintenance can be hard and risky.

So, is there a way to use the same routines in all our projects without importing (and duplicate code) ???

Hi,
You could create a reference project with all your routines (If you have enterprise version).

Hi Eric, thank for reply.

We're using TOS 6.3

This is easy to resolve. Move your routine code to Eclipse (or similar), compile them into a Jar and import the Jar into Talend. This way you can have strict control over the source code and ensure that people aren't subtley changing them in different projects. I have used this method when working with Talend Enterprise and Talend Open Source.

Thank you Richard,
Sounds like the final solution for us.

Can you tell me how can I import the Jar into Talend? I have to do that in every Project?
And how can I use my routines in my Jobs?

The easiest way is to use the tLibraryLoad

Ok, Thanks Richard,

But I wouldn't like to add a tLibraryLoad component in every Job.. It's not so neat

Sorry for the late reply, I've been away.
You can also go to Window --> Preferences --> Java --> Build Path --> User Libraries ....and add the library there.
You can also add the library to a routine "wrapper" and use the wrapper to make using it a bit easier for developers.

Wow.. that's a good tip.
Thanks Richard, I'll give it a try.

Hi Richard,
I was trying to make that world without good news.

This is what I do:
1) I made a simple code on Eclipse.
2) Export the code as a .Jar file.
3) Configure user libraries as you say.
4) Create a dummy Job for test.
5) Get this error:

Execution failed : Job compile errors 
At least job "Test_Procesos_JAR" has a compile errors, please fix and export again.
Error Line: 306
Detail Message: TestClass cannot be resolved to a type
There may be some other errors caused by JVM compatibility. Make sure your JVM setup is similar to the studio.

Hi,
After hours of trying, now I can import the library in a tJava, instance an Object and see there attributes and methods, but I get this error when I try to run:
