Talend open studio 7.0.1 Proxy problem

Anonymous — Sat, 16 Nov 2024 08:15:51 GMT

Hello,

I'm currently using Talend 6.4.1 with success. A few months ago I tried to use TOS DI 6.5.1 but had no luck with the proxy setting. I found a Jira indicating that some proxy issues has been solved here. So open studio 7.0.1 should be ok now.

I downloaded TOS DI 7.0.1 and noticed the problem was not solved for us.

I tried to dowload the basic glazedlist for the context tab but cannot download the file.

When using native proxy configuration. Talend log file shows a problem saying username is null.

When using direct, no connection is possible in http. It's normal since I have to go through the proxy.
Whenever I'm using manual settings, I can use a direct connection to internet in https and use proxy for http while using a custom firewall rule to open https traffic for my ip. I'm able to download the jars.

This was only for testing purpose, we should go through the proxy for https too.

When hitting the username is null error, we tried to force credentials.

But when we save the settings, the credentials are not saved. We reopen the network settings and credentials are gone as shown bellow.

We also tried to manually edit org.eclipse.core.net.prefs but authentication settings are not modified in talend, other parameters are correctly updated.

Finally we tried to whitelist the update site of talend in the firexall but with no luck to since it seems to open connections to a lot of others servers (2.18.132.* range mostly and others too). After 10 minutes adding new whitelist IP we still had new ones coming up, it's not safe to add ip's this way since if a new one comes up, we will be stucked again.

So we have two solutions :

- Setting a specific rule for https for talend because it does connect to the proxy correctly in https which seem not a gracefull solution.

- Find how to correct this issue with talend.

I add the log file showing connection problems.

Could you help us?

Regards.

Hello,

I found a solution to our problem.

Credential are not saved due to an eclipse configuration problem.

The first time talend open studio (>=6.5) or eclipse is installed, we have to configure secure storage in order to passwords to be saved.

Go to Window=>Preference=>General=>Security=>Secure storage then change master password. This simple step allowed us to save our proxy password and thus we were able to download additional components.

Regards.

Hello,
I want to give TOS a try and as a first test I wanted to setup an Oracle-DB connection.
This fails (wanting some odbc7.jar whilst stating:no network connection).
This is nothing unusual for me as most software products cannot connect through our firewall with standard settings.

(Authentication required)

I noted TOS does try to use the eclipse settings -which do not work.
I got eclipse to work only by editing eclipse.ini and setting (at that time only the Dhttp) proxy there.
But that doesn't seem to work for TOS.
I use the "Install additional packages" menu point for testing, tried all kinds of proxy modes, without success.
Also edited the TOS...*.ini but that seems to be for Talend connections.

best regards Max

Hello @mk65

Are you able to install it manually from Talend Modules view, download this jar from nexus server and then install it from Talend Modules view?

Best regards
