Hi Marius,

I am sending you a detailed example try to follow it:
for ProcessPanel.Spec.xml and install.xml find the attachments:

com.traderoot.tools.artifact.installer.LicenseInstall class:

public class LicenseInstall {
public void run( AbstractUIProcessHandler handler, String[] args)
{
	String installPath = args[0];
	String trtLicense = args[1];
	String tradeRootInstallationPath = args[2];
	String tradeRootRepositoriesPath = args[3];
	String check = args[4];
	String output = null;
	
	if(check.equals("Selected"){
	output = "install path is: " + installPath + "\n";
	output = output + "trtLicense variable contains: " + trtLicense + "\n";
	output = output + "tradeRootInstallationPath is: " + 
tradeRootInstallationPath + "\n";

	}	
	
	try {
	 FileWriter propWriter propWriter= new 
FileWriter(tradeRootRepositoriesPath + "/MyProp.properties");
	 BufferedWriter outBuffer = new BufferedWriter(propWriter);
	 outBuffer.write(output);
	 outBuffer.close();
	}
	catch(java.io.IOException ioe){	 }	

}
}

Hope it will help.

Regards
Mandeep
