Getting Java System Properties in ColdFusion
A while back I wrote some CFML code to dump the Java System Properties, the code went something like this:
<cfset system = CreateObject("java", "java.lang.System")> <!--- properties is a java.util.Properties object ---> <cfset properties = system.getProperties()> <!--- propNames is a java.util.Enumeration ---> <cfset propNames = properties.propertyNames()> <cfoutput> <cfloop condition="propNames.hasMoreElements()"> <cfset propName = propNames.nextElement()> <strong>#propName#</strong> = #system.getProperty(propName)#<br /> </cfloop> </cfoutput>
That works (the code didn't work in until CFMX 6.1, see this post), but I realized today as I wanted to display the results in a table much like the way CFDUMP works - that a java.util.Properties object
is a java.util.Dictionary, and a ColdFusion
structure is a
Dictionary so I can probably CFDUMP a
Properties object. And you can infact CFDUMP a Properties object or any Hashtable, and it will output the values in a table just like a structure. So now I can dump the java system properties in a table with only two lines of code:
<cfset system = CreateObject("java", "java.lang.System")> <cfdump var="#system.getProperties()#">
