Problems setting up proxies using jvisualvm

Question

I tried jvisualvm.exe in my JDK (1.6.0_15-b03) to reload the plugin directory by doing

Tools> Plugins> Updates> Update Directory

Nonetheless; no matter what proxy configuration I'm trying (I also tried checking it on another JVM 1.6 update 23) and it doesn't seem to work. I get the following errors regardless of proxy settings.

Unable to connect to the VisualVM Java Plugin Center due to sun.security.validator.ValidatorException: Failed to create PKIX path: sun.security.provider.certpath.SunCertPathBuilderException: could not find a valid certification path for the requested target

Here is the error window that appears [see attached image]

Is this a known issue or a certification issue? I never created a trust store on my machine, could that be the problem?

Answer 1

VisualVM has been ported to Github, so the plugin center is now here

but to make it short, what you need to do is open VisualVM
open Tools → Plugins → Settings
in the right column (" Java VisualVM Plugin Center ") click Edit
replace everything you have there: https://visualvm.imtqy.com/uc/8u131/updates.xml.gz

Answer 2

Here you can download plugins manually: http://visualvm.java.net/pluginscenters.html

Answer 3

Another way to achieve this is to download the plugins manually and then install them on JVisualVM.

Here are the steps:

1. Start by choosing a plugin version from: https://visualvm.imtqy.com/pluginscenters.html
2. Then download the specific plugin (file extension ".nbm") that you want to install.
3. Then in JVisualVM go to Tools> Plugin> Downloaded ; then click " Add Plugins " and select a previously downloaded file.
4. Once it appears on the Downloaded Plugins tab, then click Install .

Hope this helps ...
