Unable to open Eclipse Marketplace or Install new software after installing RDi 9.8

  • 1.  Unable to open Eclipse Marketplace or Install new software after installing RDi 9.8

    Posted Mon October 09, 2023 12:45 PM

    So far I love RDi 9.8 except for one nagging problem. 

    I am getting an error when trying to download plugins from Eclipse Marketplace or Install New Software.  (from the Help menu).

    I am running 64 bit Windows 10 on a Dell laptop. 

    I created a folder C:\RDi and copied the downloaded RDi zip file to it. Then used 7-zip to extract the zip file to the folder.  Installed my license without a problem. RDi works flawlessly for me other than this.

    Initially, I was able to open Eclipse Marketplace initially and installed the Eclipse Web Developer Tools 3.25 which allows me to edit html files.

    But now when I try to install new software (I was looking to install Git) I get an error either trying to open Eclipse Marketplace or Install new software. 

    The error I am getting is 

    Cannot open Eclipse Marketplace
    Cannot install remote marketplace locations: Cannot complete request to http://marketplace.eclipse.org/catalogs/api/p: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

    I have been trying to resolve this issue with IBM support for a couple of weeks and they are unable to duplicate my problem.

    The problem might have something to do with the Java cacerts file.

    I have no problem accessing the url's from my web browser.

    I tried uninstalling and re-installing my JRE.  I am using IBM Semeru jre-17.0.8.101-openj9.  This is IBM's recommendation for IBM i ACS. 

    RDi has it's own java

    Each has their own cacerts file.  The error logs don't tell me what cacerts file is being used. I saw some reference that it might use the one in the JAVA_HOME directory which is the IBM Sereru installation. 

    There are several other cacerts files on my system. I tried copying and replacing the cacerts files in the Semeru and RDi directories. 

    I tried uninstalling and re-installling java. 

    I uninstalled dbeaver which was running on another version of eclipse. 

    I was able to get it working again if I completely removed the C:\RDi folder and re-installed it. 

    However, I can't get that to work any more.

    I am able to get it to work if I install on my other computer - desktop machine - 64 bit Windows 10.

    I tried creating a new workspace thinking there was a setting in the workspace that could be causing the problem. 

    I think there must be some settings outside of the install folder (C:\RDi) and the workspace folder.  Perhaps some registry settings?  Maybe some ini files somewhere else.  

    Anyone else experience anything like this?

    Any suggestions?
