Getting Environment Variable

peterm1 — Sat, 16 Nov 2024 12:13:30 GMT

I'm using Talend ESB Enterprise and am running a tJava that needs to look at an Environment variable. When I run it local on my machine I get the value no problem. When I push it to Karaf the value is null. I wrote some test code to make sure the value is set correctly on the bus and it is but whenever I run a job on Karaf I get null.

Hi,
how do you read the env. variable? could you post the code snipet? (+ platform, version,..)

I'm trying to do just a simple getEnv. Do I need to do something different because it's using maven to run the job?
context.new1 = System.getenv("TEST");

well, I expected a little bit more information. to help you.
- how do you set the env. variable? as a jvm parameter? as an env. system variable?
- what platform do you run on? did you export the env. variable? how do you start the esb runtime (bin/trun, bin/start, as a service?)?
have fun

I'm running the ESB on Ubuntu with JAVA 1.6 u32 and I am exporting the environment variable at the OS level. I've written a small test harness using java code to pull the variable and I get it through there but not the BUS. I start from bin/trun and no I am not pulling it in as a JVM paramater I should not half to since it is a System level variable System.getenv should work in that case.
So just to be clear and give you more info below is the set of the OS variable
export TEST=MYTESTVAR
JAVA code in talend job
context.new1 = System.getenv("TEST");

Hi,
indeed seems this way it doesn't work under linux
If you have an enterprise edition, you may fill a support request if that's a blocker, (well, at the end of the day you will need env variables in production deployment ) until then let's find a workaround..

Hi,
so - it works for me. You have to set env variables into ~/.bashrc (so it will be available for new forks too)

test=123
export test

you can reload envs as source ~/.bashrc
hope it helps
