Important Info For Caltech Users Off-Campus
It appears that due to changes in Java security settings, the Java structure editor will NOT work while connecting through the library proxy. You MUST log into the Caltech VPN first (Select Option 2, Tunnel All), then access SciFinder.
Windows Configurations [Last Updated 04/02/2014]
Please Note: Oracle has disabled the functionality of older versions of Java. As such, only the most recent version of Java will be tested and listed here. In addition, your computer security settings may be set to block any older or outdated versions of Java. If you receive an error of that nature, contact your system administrator about changing the security settings. More information can be found here.
You should get prompted to allow the Java Structure Editor to run. This popup may be hidden behind other windows on your desktop. If your SciFinder window greys out, check behind it for the window allowing the applet to run.
The most recent tested configurations for the structure drawing Java plugin:
- Windows 7, Java 1.7 update 51 build 1.7.0_51-b13 (32-bit) [Last Updated 04/02/2014]
Go to Control Panel -> Java -> Security tab -> Edit Site List... -> add "https://scifinder.cas.org" -> OK -> OK (to exit the Java Control Panel)
- Internet Explorer 11 (Version 11.0.9600.16521, Update Version 11.0.4 (KB2925418) - WORKS if you do the following: Under Tools -> Internet options -> Security -> UNCHECK "Enable Protected Mode"
- Firefox 28.0 - WORKS
- Chrome 33.0.1750.154 m - WORKS - see the "Additional Help" section below, you may need to "activate" Java by going to the JavaTester site and allowing the plugin to run.
- Opera 20.0.1387.82 - WORKS
Note about 64-bit Java and Browsers:
- Chrome & Opera: As far as can be determined, Chrome is currently only 32-bit on Windows, and will prompt for installation of 32-bit Java in order to function. IE & Firefox will also prompt for this, and the applets will run as expected.
Note About Mac Browsers: Java 7 is ONLY 64-bit on the Mac OS X platform. Therefore it is currently not supported in Chrome for Macintosh (Chrome is 32-bit only) or Opera 16+ for Macintosh (since it is built on Chrome's architecture). Therefore, the structure editor in SciFinder will not work in these browsers under any circumstances.
Please Note: Oracle has disabled the functionality of older versions of Java. As such, only the most recent version of Java will be tested and listed here. In addition your computer security settings may be set to block any older or outdated versions of Java. If you receive an error of that nature, contact your system administrator about changing the security settings. More information can be found here.
- Mac OS X 10.9.2, Java 1.7 update 51 build 1.7.0_51-b13 (64-bit) [All Last Updated 04/02/14]:
- Safari 7.0.3 - SORT OF WORKS - Safari needs to be allowed to run this applet in "Unsafe" mode (Safari -> Preferences -> Security -> Manage Website Settings... -> Java -> scifinder.cas.org, select "Run in Unsafe Mode" from drop-down menu)
- Firefox 28.0 - WORKS
- Opera 12.16 build 1860 (64-bit) - NOT WORKING
Be sure to click on any popup or option that asks you to allow the Java applet to run. In Firefox, this may appear as an inconspicuous bar along the top of the browser window and not a separate popup. It also may take literally 2-3 minutes to load, so please be patient.
Please let us know about any problems you encounter on library computers, either directly to me (dtwrub AT caltech DOT edu) or to library AT caltech DOT edu.
If you are having problems launching the Structure Editor, follow these steps:
- Go to http://www.javatester.org
- Click on "Test the version of Java your browser is using", and click to allow any Java applets to run.
- Click on "Inactive plug in" in the blue box under "The version and vendor from the JRE".
- If it hangs (i.e. the Java logo 'spinning wheel' appears but doesn't move), reload the browser page.
- Your Java version should now display in the pink box. You should use Version 7 Update 51 (1.7.0_51).
- Launch the SciFinder Structure Editor. If it doesn't work, follow the Steps listed below to clear out the Java cache and re-install certificates.
Try launching the Structure Editor. If it still doesn't work, try the following steps, then repeat the applet activation steps above:
- Open the Java Control Panel.
- Mac: System Preferences (under the Apple menu) -> Java icon (near the bottom)
- Windows: Control Panel -> Java
- In the Java Control Panel, on the "General" tab, click "Settings".
- In the "Temporary File Settings" window, click "Delete Files".
- In the "Delete Files and Applications" window, leave the first two options checked. Click OK.
- Close the "Temporary Files Settings" window.
- On the Java Control Panel window, click "Security".
- Click "Manage Certificates".
- Highlight any certificates from "American Chemical Society" and click "Remove". Click OK.
- Close the Certificates window and the Java Control Panel.
- Repeat Steps 1-6 above (accessing javatester.org) to activate the applet.
After performing all these steps, the SciFinder structure editor should now work - if you get a permissions box popup, allow it to run.
