How to externalize plugin properties outside

Question

Hi All, 
 Good morning.. 
 We have developed a custom plugin which is constructing Json data while taking the details from server. 
 As of now there is lot's of hard coding in plugin. we want to externalize all those hard coded properties outside of plugin so that we can manage it 
 through Appian server or Jboss server as these properties are different environment to environment. 
 Please provide your valuable help in this. 
 
 Thanks & Regards-

Hi ruchiagarwala as per my understanding, you cannot expose custom plugin properties file outside. If you have lot many hard coded values in your plugin code (which is not a good practice if these data vary in different different conditions), you should parameterize these fields so that you can pass the values from Appian accordingly. 
 
Hope this will help you.

You might try using Appian Constants for this, and using the ContentService to retrieve constant values from within the Java code.

Hi @ruchi i agree with @jim you can instantiate ProcessDesignService class object using ServiceContext class as mention below 
 
ProcessDesignService pds = ServiceLocator.getProcessDesignService(context); 
 
This pds object will allow you to evaluate a constant which exists in your Appian environment. 
 
For more details you can explore about PricessDesignService class in Appian API 
 
Hope this will help you.
