| < < | Apple blocked WebStart and Java applets in certain versions of Java. It is possible to remove this block, but: It is very important to realize the security threat that removing the block poses. If you use Java 6 in your browser, you will be open to the security problem explained above, and we advise strongly against removing the block in this case. Therefore our recommendation is to start by installing Java 7 for use in the browser.
Install Java 7 in the browser: Go to http://www.java.com and click the button "Free Java Download". You can check the Java version that your browser uses by visiting http://www.javatester.org/version.html. "Java 7 update 13" is reported as "1.7_13".
After this step, Java 6 should only be used to run HIPE and to start WebStart applications from HIPE. Because we trust that the applications started by HIPE do not contain malware, we can then remove the block on Java WebStart and Java browser plug-in for this version. We will not use the Java browser plug-in, but both are considered under the nomer "Java plug-in", so we can only enable or disable both.
Remove the block on Java 1.6 update 37:
sudo /usr/libexec/PlistBuddy -c "Set :JavaWebComponentVersionMinimum 1.6.0_37-b06-434" /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/XProtect.meta.plistUnfortunately, just as Apple has initially silently applied this block, they can come back and re-apply it, even though it's been manually removed. This has been reported to happen after reboots. If it happens, one can simply execute the above command again. You can also execute the command below, which updates the "last modified" date in the relevant file, which has been said to stop Apple from updating the file on your behalf: sudo /usr/libexec/PlistBuddy -c "Set :LastModification Fri,\ 08\ Feb\ 2014\ 00:54:09\ GMT" XProtect.meta.plist | ||||||||||||
| > > | In order to start the HSA User Interface from the browser, make sure to update to the latest version of Java 7 by visiting http://www.java.com. If you have a HIPE installation using Java 6, installing or updating Java 7 will not affect it. After installing or updating Java in the browser, WebStart applications can be started from there. In the case of the HSA UI by going to http://archives.esac.esa.int/hsa/ui/hui.jnlp. | ||||||||||||

| > > | The other possibility is to uninstall Java 6, install Java 7 and re-install HIPE. This way, HIPE should run on Java 7. HIPE has not been validated to work correctly on Java 7, but we have no reason to believe that there are any issues. We plan to provide a more detailed procedure on how to go about this installation in the future. | ||||||||||||
