I want to run the .exe file, but the hosting block cfexecute

We do not allow the "cfexecute" tag to be enabled on our shared servers for security reasons.

Search for solutions on the Internet, I found a project systemcommand.jar

java -version (Used to test the code)

Example 1 (SystemCommand_1) Code works

<cfset cmd = "java -version">
<cfset runtime = createObject("java", "java.lang.Runtime")>
<cfset process = runtime.getRuntime().exec(cmd)>
<cfdump var="#process#"/>

Open in new window

Example 2 (SystemCommand_2)  Code works

http://blog.stannard.net.au/2007/9/21/executing-system-commands-with-coldfusion/

<cfset command = "java -version">
<cfset syscmd = createObject("component","SystemCommand").init()>
<cfset result = syscmd.execute(command)>
<cfdump var="#result#">

Open in new window

Example 3 (SystemCommand_3) Why the code does not work

Application.cfc

component output="false" displayname="" {

	this.javaSettings.loadPaths = [expandPath(".\systemcommand.jar")];
	this.javaSettings.loadColdFusionClassPath=false;
	this.javaSettings.reloadOnChange=true;
}		

Open in new window


test.cfm
<cfset command = "java -version">
<cfset syscmd = createObject("java","au.com.webcode.util.SystemCommand").init()>
<cfset result = syscmd.execute(command)>

<cfoutput>
Command: #result.getCommand()#<br />
ExitValue: #result.getExitValue()#<br />
Error Output: #result.getErrorOutput()#<br />
Standard Output: #result.getStandardOutput()#<br />
</cfoutput>

Doesn't work how? Please post any error messages you're getting.

..
<cfset process = runtime.getRuntime().exec(cmd)>

I'm surprised that works at all.  cfexecute is simply a wrapper for Runtime.exec. You may not want to plan on this as a long term solution, since your host could easily disable it too ...

You can zip your exe up and that will make it possible to be downloaded, unzipped on the clients computer and then execute the exe.

It's the "reloadOnChange=true" setting. When it's "false", everything's peachy. But change it to true and you get errors. The docs say it _should_ work, but it doesn't (probably a bug).  The only solution I see is to remove that param.  

Important:  javaSettings's are only evaluated once. If you make changes , you  _must_ also do something to force a reload so the changes are applied (like changing the application name)

Works:
    this.name = "NEW application name 1 here";
    ....
    this.javaSettings =
        {
            LoadPaths = [ ExpandPath("./systemcommand.jar") ]
            , LoadColdFusionClassPath = false
      };

Fails:
    this.name = "NEW application name 2 here";
    ....
    this.javaSettings =
        {
            LoadPaths = [ ExpandPath("./systemcommand.jar") ]
            , LoadColdFusionClassPath = false
            , reloadOnChange="true"
      };
