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
