How to set SOCKS(v4) proxy in tRestClient

Anonymous — Wed, 06 Sep 2017 13:22:22 GMT

Hi,

I'm trying to access a Rest-Webservice from Talend, I used tRestClient but to access the WebService i need to configure SOCKS(v4) proxy,

So i used tSetProxy---------Component OK ------------>tRestClient-----------(response)---------->tLogRow.

but it throws an exception (attached the log file logs.txt).

1. tSetProxy (Basic Setting: Proxy type: Socks proxy || host: 127.0.0.1 || port: 1111
2. tRestClient(Basic Setting: Url: https://***.slnec2.lab.443/**, Relative Pathe: "88-100")

If I provide the same proxy in Firefox then I get the response easily from MozilaRestClient.

Please help

Does the SSLHandshakeException only happen when POST? or happon for any GET/PUT/POST?

Have you tried to use tSetKeystore to load the certification before you connect to REST using tRESTClient for https end point?

Best regards

sorry for replying late

Yes SSLHandshakeException happens for every operation. 1st i have download the certificate(.crt file) then convert it into .jks file using keytool. and use the same in tSetKeyStore, and I have used tSetProxy for SockProxy then tRestClient is use to call the rest client.

tSetKeyStore--------------OncomponentOK----------->tSetProxy-----------------OnSubject OK---------->tRestCleint---------tLog

And now it throws an exception (please find the attached log file).
