I note that Oracle Java 7 has been EOL for three years. The error that you quoted is what you get when you run code compiled for Java 8 on an older JVM. It appears that your PostgreSQL driver was compiled for Java 8, and JDK 7 won't load it. You may be able to find a version that is compiled with JDK 7 at https://jdbc.postgresql.org/download.html In your position, yes, I would upgrade to Java 8. -- You received this message because you are subscribed to the Google Groups "DSpace Technical Support" group.

Thanks, Paul: I will try and see if I can get things working following your directions.

[dspace-tech] Re: REST API not working
Hi, It sounds like you are having other problems, George, but I just struggled with Dspace's Rest interface, and I can confirm the Apache Proxy/ReverseProxy problem. That stumped me for a while, because we are running https through Apache, and I thought I should leave the https in. But we are not using https for Tomcat, of course (duh!), since it is running behind Apache - so I had to comment out the https segment in the Rest config before I could get it to work. I have tomcat configured to listen only on localhost, so I can now access the Rest interface only on that machine. I use curl on the command line. Everything works. But I have not included rest in the Proxy/ReverseProxy list for Apache, so it is not available in the browser. I get a 404 just like you do, George. I do not want everyone to be able to use it online, so this suits me. I post this because these kinds of fine points can be overlooked. I hope it helps someone.
