Java 8 update 25 doesn't work

A Former User

HELP!
I uninstalled java 8.0.25, and installed java 8.0.20, and now when I go to the test java page I get this box::
"For security, applications must now meet the requirements for the High or Very High security settings, or be part of the Exception Site List, to be allowed to run. More Information."
then below that there is another line that says,
"Your security settings have blocked a self signed application from running."
I believe this is something that was enabled when I had installed update 25 and now it was not changed when I uninstalled it
What now??
HELP again.

They changed the format of the security settings tab in the Java control panel in recent versions.
It may be that the settings from your previous (later) version stuck.
Run the applet in the Windows Control Panel, and look at the Security tab.
There should be a slider set to the mid position by default (high).
If it isn't set to that change it and see if it will now let things run.

Hi guys!

I had same problems as davews:

Just to clarify. All pages load normally. However with any page that uses java applets the applets do not appear to load at all - on Firefox you get a popup asking you permission to run the applet, no sign of that in Opera. eg the Independent crossword site: http://www.independent.co.uk/extras/puzzles/crosswords/?crosswordType=cryptic where the crossword, which is run in an applet, fails to load. Java was updated via the Java control panel interface and clearly came from oracle. Opera 12.16 on Windows 7 x64.

If you have installed 64-bit Java version, but your web browser is 32-bit, then you should also install 32-bit Java version, as is prompted on this page on Java website: http://java.com/en/download/manual.jsp

We have detected you may be viewing this page in a 32-bit browser. If you use 32-bit and 64-bit browsers interchangeably, you will need to install both 32-bit and 64-bit Java in order to have the Java plug-in for both browsers.

It helps in my case
Cheers!

Here if install both 32 and 64 bits versions of Java, Opera doesn't recognize the plugin.

Java Verify failure unable to Configure Java Control Panel does not open ( Fix : )
this is a regular ( windows 7 bug related ) problem after successful installation of Java ( jre ) and fresh installation of Windows7 64bit or 32bit on my laptop or desktop. what worked perfectly for me was setting COMPATIBILITYMODE=WINDOWSNT to make windows launch the JP2LAUNCHER.EXE and JAVAW.EXE files properly.
jp2launcher.exe windowsNT compatibility solves Java Verify failure problem at https://www.java.com/en/download/installed.jsp
javaw.exe windowsNT compatibility solves unable to open or Configure Java Control Panel problem.

*  search for JAVAW.EXE   inside  c:\program files\java\....\bin   
      or  c:\program files(x86)\java\.....\bin\
*  right-click mouse on  JAVAW   application icon logo
*  click  PROPERTIES
*  click  COMPATIBILITY
*  tick the checkbox at COMPATIBILITY MODE
*  choose  WINDOWS NT service pack
*  click APPLY or click OK

Now, the Configure Java Control Panel will start opening and working.

*  search for JP2LAUNCHER.EXE   inside  c:\program files\java\....\bin   
      or  c:\program files(x86)\java\.....\bin\
*  right-click mouse on  JP2LAUNCHER
*  click  PROPERTIES
*  click  COMPATIBILITY
*  tick the checkbox at COMPATIBILITY MODE
*  choose  WINDOWS NT service pack
*  click APPLY or click OK

Now, the Verify Java will be successful at https://www.java.com/en/download/installed.jsp

if we find 2 or 3 versions of JP2LAUNCHER and JAVAW when we search, then we must repeat the above for all of them.

in the Configure Java Control Panel Advanced tab we can set "Do not check" certificate revocation and disable security verification. and in the Security tab we may Edit Site List... for the Exception Site List ( add URLs to unblock sites )

Just tried the above JP2LAUNCHER.EXE compatibility setting and still no Java applets (like the test/verify link) will run in Opera 12.17. Java is version 7 update 80. All works fine in FireFox, also Java Control Panel works fine.

Basically, Java seems broken in Opera.

Java 7 Update 67 is the last version of Java where the plugin will work in Opera 17.
All subsequent versions of Java 7, and all versions of Java 8, will not work unless you replace the plugin file NPJP2.DLL with the version from Java 7 Update 27. I've done that and it works fine with the latest version of Java 8 even on Windows XP, but there may be security implications to this of course, and you do get nag popups warning you that Java is out of date.
This is not something that's ever going to be fixed now I'm afraid, either by Oracle or by Opera themselves, so it's the only workaround I know of, and at least it means that the rest of the system is using the latest Java.

I used that trick (replacing npjp2.dll and npdeployJava1.dll with the ones from jre 8u20) and it worked ok until after version 8u66, i.e. 8u66 is the last version with which that trick works for me.
If I do the same with either version 8u71, 8u72, 8u73 or 8u74 there's no difference to not replacing those files.

Has anyone an idea which files now might also need replacing to get the current versions of jre run with O11/O12?

A Former User

I strongly suspect that it's no longer possible at all I'm afraid with the latest Java versions.

A Former User

Too bad. But thanks for confirming my experience and thoughts.

A Former User

No problem.
If you must have Java working in Opera 12, the last version that works normally without workarounds is Java 7 Update 67.
