问题
I'm developing a Java application that connects to SOAP services exposed at https://ut.eurodw.eu/ (test environment for European Datawarehouse). I'm working on my development machine, recently reformatted with Windows 8.1. Today, I tried to send them a creation request via SOAP from my program and got this error:
Caused by: javax.xml.ws.WebServiceException: Could not send Message.

As you can see by clicking my above link, that's no self-signed certificate, but released by GoDaddy public CA, recognized by my Firefox browser. My Java version is 1.7.0_60-b19. It will be a bad idea to modify the code in order to allow insecure SSL connections.
I'd like instead to ensure that eurodw's certificate is in the trust store. How do I check that? And how do I possibly import a new certificate?
PS I cannot currently test on the server where the final application is deployed: I can only use my own Tomcat installation.
回答1:
The different certificates can be found in the following keystore :
%JAVA_HOME%/jre/lib/security/cacerts
If you want to list the trusted certificates :
keytool -list -keystore %JAVA_HOME%/jre/lib/security/cacerts
The password is optionnal to list.
If you want to add an entry :
First, export the certificate to import, let's say it will be c:\cert.crt. The best way to do it is using firefox, right click on the lock picture in the url, and after a few clicks, you have an export feature.
Then type :
keytool -import -alias my-cert -file c:\cert.crt -keystore %JAVA_HOME%/jre/lib/security/cacerts
The password is : changeit
The alias being a user defined label, choose it wisely, to remember if you need it one day, what it was.
With all this, you should be able to trust the certificate and have everything working again.
