Configuring Proxy Correctly and Errors Fetching Third Party Jars

Anonymous — Sat, 16 Nov 2024 08:52:31 GMT

Hi All,

I am having issues downloading any package. I think the proxy configuration may be causing the failure and/or there are a bunch of broken locations in the Talend repository.

1) My office uses a proxy to direct request network requests. Attached is proxy configuration with proxy greyed out. However, there is a warning saying I have to change the system property to 8080. What and where are they referring to in Talend when they say system property because both ports are set to 8080 as you can see from the screenshot of the proxy configuration?

!ENTRY org.eclipse.core.net 1 0 2018-01-11 15:27:15.220
!MESSAGE System property http.proxyPort is not set but should be 8080.

!ENTRY org.eclipse.core.net 1 0 2018-01-11 15:27:15.236
!MESSAGE System property https.proxyPort is not set but should be 8080.

2) I am wondering if the proxy configuration is causing me to have issues downloading and installing packages. Attached is the log where Talend cannot find many libraries in its repository (mostly start iwth the url mvnrg.talend.libraries/) including errors at the bottom of the log mentioned in a and b.

a) 2018-01-11 15:27:30,870 ERROR org.talend.dataprofiler.core.download.AbstractDQMissingJarsExtraUpdatesFactory - failed to fetch missing third parties jars information for org.talend.dataprofiler.top.chart.jar

Hello,

You can download external modules and install them directly into your Studio.

Here is online document about:TalendHelpCenter:Installing external modules from within the Studio.

Best regards

Hello,

so how do I access that dialog box 'Download external modules?' If it is supposed to come from Additional Talend Packages under Help menu, this is what happens when I click that option. It gives me all the errors I got in the first post above. It is trying to download them, but nothing shows up here. It am assuming it is because of the errors mentioned in the first post. Btw, this occurs after I have added the talend update link to the proxy settings you mentioned in the other post.

I have the same problem, but still without a solution.

I adopted this workaround:

- Install TOS in a pc with direct access to internet, without a proxy.

- Let TOS download everything it needs

- Copy all the stuff in my pc behind the proxy.

I find it really terrible, but I didn't find anything better.

Any suggestion to do something better?

Hello duccio,

How did you configure your proxy?

Could you please clarify in which Talend version/edition you are? The network setting comes from Eclipse documentation: see Proxy entries under Workbench User Guide > Reference > Preferences > Network Connections.

If you are working behind a network proxy, make sure you have correctly set up your proxy and add the web site talend-update.talend.com and the port 443 to whitelist.

Best regards

Sabrina
