When running Java or other types of applications which use an XML file as part of the input, you may see this error: The Processing Instruction Target Matching “[xX][mM][lL]” is Not Allowed.
Often the cause is a malformed XML file, with a common problem being a blank line accidentally inserted before the required first line of the xml:
[ A blank line here will cause the error ] <?xml version-"1.0"?>Continue reading

While setting up Nutch on a Mac, I kept getting this error in the terminal:
Error: JAVA_HOME is not set
To fix the error on OS X 10.6.x (Snow Leopard), enter the following at the command prompt:
export JAVA_HOME=$(/usr/libexec/java_home)
On 10.5 and above, the command line tool /usr/libexec/java_home dynamically finds the top Java version specified in Java Preferences for the current user. Using this method will allow the path to automatically change as software updates change Java versions.

If Firefox won’t launch java applets, but Internet Explorer will, you may need to change some settings in the Java control panel to turn on Applet support for Firefox.

The z-index bug in action
Although Internet Explorer 8 has been widely adopted, IE 7 is still the browser in use at my office, so all new projects must be compatible with it. Even though IE7 was already obsolete when we adopted it, it was a wonderful change from IE 6, because of the reduced need for CSS and javascript hacks, workarounds and compromises in general.
So it was a surprise to realize that an old Internet Explorer 6 stylesheet problem, the “z-index bug” still lingers on. You’ll know you’ve hit this bug when your drop-down menus fall UNDER elements that are lower down on the page. (…I should add: and there are no iframes or frames on the page).
There are several sites that do a fantastic job of telling you exactly why this happens. I’m just going to tell you how to fix it. In fact, if you want to jump to the fix right now, click here
