Issue in Creating and Loading a Password-Protected Context File in Talend Studio 8.0.1

[reshnan]

Hi 

I’m currently working in Talend Studio 8.0.1 and trying to implement a secure way to handle context files.
The requirement  is to create a password-protected context file and then load that protected file within a Talend Job, instead of keeping a plain text context file.

Here’s what I have done so far:

• I created a normal .txt context file containing database connection parameters.

• I then used 7-Zip to password-protect the file (ZIP encryption).

• In Talend, I tried to use a tJava component to decrypt/unzip the file dynamically using a command like:

  String cmd = "cmd /c \"7z x C:/Talend_Files/OracleConnectionSetup.zip -pMySecureKey -oC:/Talend_Files/Extracted -y\""; Runtime.getRuntime().exec(cmd);

• After that, I attempted to link the tJava to a tContextLoad component to read the extracted .txt file and use it in a tDBConnection.

However, I’m facing issues while:

1. Properly connecting tJava → tContextLoad (so that the context file loads after decryption).

2. Ensuring that the password-protected ZIP is handled securely without exposing the password in the Job.

Could someone please guide me on the best practice or recommended approach to:

• Create and load a password-protected context file, and

• Use it safely inside Talend .

Any example or step-by-step guidance would be very helpful.

Thanks in advance!

Hello

After you decrypt/unzip the file on tJava, use a tFileInputDelimited to read the context variables from the password-protect file, eg:

tJava--OncomponentOK--tFileInputDelimited--main--tContextLoad

Please refer to this link Preparing the contexts and context variables | Qlik THC documentation to define the context variables.
