context parameter in java to TALEND job

Anonymous — Sat, 16 Nov 2024 10:53:07 GMT

hi,
i want to pass one context variable from java code to talend job.The vaue contains path of CSV file.
I want to pass that path value to 'tFileInputDelimited' component and then to MSSQL database.
First 'tFileInputDelimited' is empty but File name/Stream has file path passed from javacode.
Now 'tMap' component is empty.
How to solve this problem?
One more doubt is how can i get context variable 'file_path' (which is defined in java code) in TALEND JOB and set path value to 'File name/Stream' of ''tFileInputDelimited'' component.
please look into screenshots for better understanding of my problem.

Hi praveen522,
Have you already checked the document about TalendHelpCenter:How to define context variables for a Job?
Why don't you set your file path value in Context view? Did you want to mask your file path in your job by using javacode?
Best regards

Hi,

I think you have already read this KB article TalendHelpCenter:Calling a Talend Job from an external Java application
We see your code is OK to call the job from eclipse and pass the new values to context variable.
So now, what is the problem if you run the java code?
Best regards

hi xdshi,
I think you will understand my problem clearly and identify mistake i made once you go through my new screenshots attached below.
In return i am getting "org.xml.sax.SAXException" in java class(refer screenshot 1).
EXCEPTION:
org.xml.sax.SAXException : Deserializing parameter 'item': could not find deserializer for type { http://talend.org}ArrayOf_xsd_string.

Have a look at screenshots.Identify the mistake i done here.
