@rchinta ,

.item and .properties files are just meadata: jobs, process, connections, repository elements and so on...

Metadata is mandatory for editing (designing) the job and for the very core structure of Talend workspace itself, but it's not needed fir job execution. This mean you can forget about it after you have exported the job.

.java files are the auto-generated source code for the job. You cannot use it directly because: i. many of them are generated for a even simple jobs (external routines, dependencies...) ii. components generate an intermediate set of .java files using a javajet-based preprocessor.

But you can bundle the source code when you export a job. THAT java code is self-contained and useful for intergration purpose or other advanced scenarios.

@manodwhb ,

thanks for your response, I have seen that post before posting this question in forum. however I am still not clear on exact definitions. you are saying .item and .properties are just metadata and has no use,

1)but what exact details .item and .properties file will have respectively?

2) what about talend.project file?

3) In which of these file the core java code resides?

4) when the exported job is imported in TAC or studio on some other machine, how talend engine will convert these files and execute the job?

In short I am looking for detailed techincal explanation of the while process happens when exporting and importing the job and how these segregation happens.

Also i dont think these techincal level details are not present in talend site, it would be helpful if someone can guide how to know in-depth technical knowledge on how talend works!

thanks in advance!
