Question: Unable to stage hello world java-see app

[Manish-Mj]

Hello Team,

I'm trying to understand cf local to see how I can use it in our project. Am pretty new to the cloud world as well. I installed cf local plugin & cloned a basic example from: https://github.com/18F/cf-hello-worlds
I ran the below commands but always get some certificate errors. I tried my best to import certs but still unable to go past this step. Any pointers would be helpful.

root@hostname:/code/cf-hello-worlds/java-see# update-ca-certificates

done.

Hello @sclevine any help on this is appreciated, thanks.

[sclevine]

Do you use an HTTP/HTTPS proxy to connect to the internet on your workstation?

[Manish-Mj]

Yes there is. I exported the certificate chain and added to the /usr/share/ca-certificates, but still no luck @ all.

Hi @sclevine I was finally stage the app using offline buildpack, but now another hurdle.
Its a maven app & am not able to run it. Error stack below. Any pointers are appreciated.

I got this fixed by building offline: java-buildpack version 4.12 which supports running spring app > 1.4.
But still some other errors. My end goal is to link it to remote service running in our cloud envi.
Please point me to a sample or doc which can be referred to make progress.
