Answer 1

Oracle has updated links generation mechanism. It now includes some sequence, which seems to be persistent for a version but generated with a yet unknown mechanism. Also, to download any version except for latest you're now required to have Oracle account:

For production use Oracle recommends downloading the latest JDK and JRE versions and allowing auto-update.

Only developers and Enterprise administrators should download these releases.

Downloading these releases requires an oracle.com account. If you don't have an oracle.com account you can use the links on the top of this page to learn more about it and register for one for free.

See more at Oracle Java Archives page.

So you're stuck with two options now.

Option 1. Use the latest version ( 8u131 now) by a new direct link. The link is available at the Java SE Development Kit 8 downloads page after you accept the License agreement. And your command will be:

wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-x64.rpm"

Option 2. Switch to openjdk package:

yum install java-1.8.0-openjdk

See more about openjdk installation at OpenJDK: Download and install page.

Answer 2

This kind of thing comes up repeatedly. The fundamental issue is that Oracle want you to read and agree to the license terms.

It is a legal thing. If you can implement a scheme where you can automate the downloading without a human being clicking the "I agree" button, there is a chance that some Judge may rule that the agreement terms do not apply to you.

Therefore, Oracle try to make it hard (or at least ... not simple) to automate downloads of the "free" versions of Java. And every now and then they change the mechanisms.

A couple of ways to deal with this would be:

1. Ask Oracle if they would give you access to a stable download site (presumably with password access control) if you payed for a license. (I actually don't know if they do.)

2. Manually download the distro for each version of Java that you need and save them in a safe private place ¹ . Then change your automatic deployment code to fetch distros from that location.

3. Switch to a 3rd-party provider of OpenJDK; eg a Linux package source, or one of providers who make OpenJDK binary distros available for free and unrestricted download.

I'm aware that all of the above entail some effort. But then so does "faffing about" with scripted downloads from " http://download.oracle.com " each time there is an unheralded change.

^{1 - 1) Check with your lawyers first. I think that the license allows this, but IANAL. 2) Do not deliberately or accidentally publish them, or you are liable to be on the wrong end of a copyright violation lawsuit!}

Answer 3

For me, using wget directly on my remote Linux server failed every time no matter the script used. It was either downloading the file as HTML or not downloading at all.

The best and surest way to do this install is to

1. Forget wget and download the file directly to your system
2. Use WinSCP or any other free SFTP or FTP client to transfer the file to your server
3. And then run yum localinstall <file-name.rpm> from the file location.

Answer 4

I had same issue as OP for jdk-8u131 and after checking the Option 1 command in the answer above against mine I noticed it was exactly the same. I cut paste that Option 1 answer and it worked though! So, I then tried several times again with my original call (which is exactly the same) and it failed again several times with the same message and then on about the 5th or 6th go it worked...so I think, once you are using the latest URL, that it works fine with Option 1 but you might see the 404 error on more than one occasion - if so just wait and then retry.
