Using external custom .jar in job Talend (Parsing PDF)

[Gadje]

I made a custom .jar executable that parsing some PDF files and catching some text values, depending a regex.

All works fine.

Now, i would like to use it in Talend job but i don't know how to do it.

I tried with tLibraryLoad component but it didn't work.

I tried to :

1. Create a routine in the code section. Save it.
2. Right click on the routine to edit the routine libraries. Locate and add your jar.
3. Edit the dependecies of your job and add the created routine.
4. Add the required import in a tJava component.
5. You should be able to use the library in the tJava from now

But didn't work too.

Is ther somebody who knows how i can do that.

Thanks from advance.

Hello xdshi,

Thanks for your reply.

I use Talend 6.3.1. i didn't see anything concerning TAC.

If i try to import iText directly in Talend package explorer, i have an "BUILD FAILURE" message.

I don't understand anything in the page link yau gave me. Sorry.

Hello,

Using a tLibraryLoad component to load the jar at the beginning of job, and then write the custom code on tJava, eg:

tLibraryLoad

|

onsubjobok

|

tJava

What's error are you getting?

Hello,

You could delete the configuration/.m2 and re-download the jar files which the one that is the issue in this scenario is your routines jar file.

Hello Xdshi,

I used a tLibraryLoad component as show in 1 below and i loaded my executable jar ParserPdf.jar as show in 2, 3, 4.

 

I connected the tLibraryLoad component to tJava componenent with OnSubjobOk link.

I just called my class as show in 2.

 

This is the issue message i obtain in 2

 

I deleted the /.m2 repository but i dont know what to do after.

Thanks from advance.

I tried another way with tSystem component as show below.

But i didn't catch nothing in my consol output.

I continue my quest. 😅

Hello,

To enable this tLibraryLoad component to load an external library, you need first to import the library into the component.

Hi,

I found how to do for displaying returned values from my .jar with tSystem component. But now i would like to know how catch this values in a tMap component.

If i use this configuration (console output) :

 

I can displaying the values returned by jar :

 

But if i configure the tSystem output to global variable as below :

 

i don't have anything in output :

 

Maybe my problem come from my jar code. i puting it here :
