Not able to add certificate from Alfresco - in local Windows-Eclipse environment

[SG]

I am trying to run the driver-Java-code locally inside my Windows-Eclipse and attempting to make the HTTPS call to a webservice deployed in a different Windows-Alfresco server.

The webservice deployed in the Windows-Alfresco server is created using Java-backed-WebScript. The webservice URL attempted to be called is similar to: https://mydomain.org/alfresco/service/extract/abc

This is what I have attempted:

I took the valid certificate from the Alfresco-Windows server and added to my local-Eclipse-Windows machine’s JRE using the following:

keytool -import -trustcacerts -alias mycertificate -file C:\Documentation\ mycertificate.cer -keystore keystore.jks

After that, I also made sure that the certificate is indeed installed and verified that using:

keytool -list -v -keystore keystore.jks

I also verified that Eclipse is also configured to use the same JRE, where I imported the certificate from Alfresco.

Even with that, I still get the error as follows, when I attempt to execute the Java-client-code from my Windows-Eclipse, attempting to call the URL deployed in the remote Windows-Alfresco server:

Called URL =https://mydomain.org/alfresco/service/extract/abc

I get exception stacktrace as:

My question:

1. Any suggestion will be appreciated.

When you do calls to HTTPS URLs protected by self-signed or other untrusted certificates, you should never rely on the certificate being added to the JRE. Instead, you custom code should use its own truststore for certificate / host validation, i.e. similar to how Alfresco uses the ssl.truststore for handling the SSL certificate validation if SOLR and Repository are set up in a mTLS configuration.

Hello Afaust,

Thanks for the response.

Alfresco-Windows-machine has a correct certificate and has no issue.

I issue is, not being able to call a URL (URL is hosted in that Alfresco-Windows-machine) from a different Windows-machine, where I run local-Java-code in Eclipse. I obtained the correct certificate from the Alfresco-Windows-machine. After that, I attempted to install that certificate in the JRE of the local-Java-Eclipse-machine. The local-Java-Eclipse-machine has Java driver code (e.g. Java main method) that calls URL hosted in Alfresco-Windows-machine. The local-Java-Eclipse-machine does NOT have any server, or anything else, only has a Java-driver class that can make HTTP(s) call to the URL hosted in Alfresco-Windows-machine. The local-Java-Eclipse-machine (even with the certificate installed in its JRE) is not being able to succeed in calling the URL of the Alfresco-Windows-machine.

My questions:

1. Are you suggesting any different configuration in local-Java-Eclipse-machine, which only has the has the Java driver (it does not have Alfresco, does not have Tomcat). It simply makes the HTTP(S) calls the URL hosted in the Alfresco-Windows machine.

2. I do not understand what exact SOLR-type configuration you are suggesting for the local-Java-Eclipse-machine.
