deploying the rest api

[Jose Blanco]

I'm able to deploy oai, solr, "/" , but the rest gives me this error:

In looking at the catalina log files, it seems like I'm having the issue mentioned here:

http://dspace.2283337.n4.nabble.com/Rest-API-not-working-in-DSpace-6-2-td4687599.html

I have java version "1.7.0_251"

I'm trying to get RESTapi to run on 63.  According to the installation instructions, I should be able to use version 7 of java,  but  it seems like maybe not.  Before I upgrade to Java 8,  I want to verify this.

Thank you!

Hi Jose,

The error described here http://dspace.2283337.n4.nabble.com/Rest-API-not-working-in-DSpace-6-2-td4687599.html occurs because you are running a version of PostgreSQL that *requires* Java 8.  

So, if you want/need to run DSpace using Java 7, you'd have to find an old version of PostgreSQL that also works for Java 7.  However, that may be difficult to do, as Java 7 has been end of life since 2015. 

It may be much much easier to just upgrade to Java 8, since whatever version of PostgreSQL you are running seems to require it.

Tim, Thank you!  One more question.  Do you think dspace 5.1 will run OK with Java 8. Our development machine is the same as our production machine, so if we upgrade that machine to use java 8, I just want to make sure it will not mess up anything with our production dspace 5.1.

Thank you!

-Jose

[Jose Blanco]

Sorry to bother you, but any thoughts on using java 8 with dspace 5.1.  Thank you!

[tim.d...@lyrasis.org]

While DSpace 5 was never officially tested with Java 8 (which is why it isn't listed as "supported"), my understanding is there are several sites that are successfully running DSpace 5.x on Java 8.

This is based on the feedback reported in our Java 8 upgrade ticket https://jira.lyrasis.org/browse/DS-2653

As well as other's feedback on this mailing list, for example: https://groups.google.com/d/msg/dspace-tech/M45uwUo69W0/mBO7m50mCQAJ

So, I think DSpace 5.1 will likely work on Java 8.  I cannot promise it though, as it was never officially tested on that release of Java.  That said, people seem to be having success at least running DSpace 5.9 on Java 8.  So, if 5.1 has issues, you could upgrade to a later version of 5.x.

We are running some Dspace instances with java1.8  and Dspace 4, 5 & 6 

Due to cross-requirements from diverse integrations with: security headers, Office365, LDAP and Twitter,  we opt in Dspace 5.x  for versions  greater than  java 1.8.0_112   but less than  1.8.0_161

in Dspace 4 we are running a Java version 1.8.0-231 without any issues (LDAP authetication )

if you need more information, don´t doubt contact me.

Emilio

Stay safe, stay at home.

Also no promises, but here we have a 5.6 instance and a 5.2 instance
running on OpenJDK 8. I do all of my development and testing with
Java 8 unless something needs Java 11.
