Every wonder a nice, quick and easy way of getting your Operating System's file separator character??

Well, I have several times. Thanks to our collaborator Ariel Gonzalez, and his java expertise. We take a look at the java.lang.System class and its getProperty() Method.

There are several useful properties that you can get from this class, some of them are listed below:

Key	Meaning
"file.separator"	File separator (for example, "/")
"java.class.path"	Java classpath
"java.class.version"	Java class version number
"java.home"	Java installation directory
"java.vendor"	Java vendor-specific string
"java.vendor.url"	Java vendor URL
"java.version"	Java version number
"line.separator"	Line separator
"os.arch"	Operating system architecture
"os.name"	Operating system name
"os.version"	Operating system version
"path.separator"	Path separator (for example, ":")
"user.dir"	User's current working directory
"user.home"	User home directory
"user.name"	User account name

The most useful properties that I have found in Coldfusion Development are:

1) file.separator 2) java.class.version 3) java.version 4) line.separator 5) os.version 6) os.name 7) path.separator

So how do we use this java class in our coldfusion code. Well, pretty simple, just two lines of code.

<cfscript>
//Get a reference to the System class
objSystem = createObject("java", "java.lang.System");
//Get the property desired, in this case, the file separator
fileSeparator = objSystem.getProperty("file.separator");
</cfscript>

and that is it!!! Pretty simple.

Is there any other way to do it that does not involve createObject?

You can do a test for windows as the OS, then just do a "\" or "/" for non-windows

Just always use "/" in conjunction with:
getCurrentTemplatePath and
path = replace(path,"\","/","all);
