Symptoms

Plugin repository cannot load the plugins list. Web browser prompts a message box:

1 2 3 Error downloading: http://confluence.atlassian.com/plugin-repository/proxy.action?profile=confluence&decorator=none&buildNumber=1627&repoClientVer=2.1.4&os=ppc&javaVer=1.5.0&javaVendor=IBM+Corporation com.ibm.jsse2.util.h: No trusted certificate found

The following appears in the atlassian-confluence.log:

Caused by: javax.net.ssl.SSLHandshakeException: com.ibm.jsse2.util.h: No trusted certificate found ... Caused by: com.ibm.jsse2.util.h: No trusted certificate found ...

Cause

To load the plugins list, plugin repository requests our SSL-enabled site at https://plugins.atlassian.com. The JVM configured for Websphere does not contain SSL certificate of this site, hence, causing the request to fail.
