如何在环境环境中将属性文件从jar加载到javascript代码

Question

Hai I am trying to read properties file from jar to my javascript code in mirth environment . I wrote js code in transformer.

I kept jar file in lib folder.

It is showing exception like:

The choice of Java method java.io.FileInputStream matching JavaScript argument types (null) is ambiguous; candidate methods are:
FileInputStream(java.lang.String) FileInputStream(java.io.File)
FileInputStream(java.io.FileDescriptor) (com.mirth.connect.server.MirthJavascriptTransformerException)

Below is the code:

importPackage(Packages.logproperties.*);
var prop=new Packages.java.util.Properties();
var fis=new     Packages.java.io.FileInputStream(Packages.java.lang.ClassLoader.getSystemResourceAsStream("Logs.properties"));
prop.load(fis);

Answer 1

Based on the error message is looks like you are calling FileInputStream with null .

That means that Packages.java.lang.ClassLoader.getSystemResourceAsStream("Logs.properties") is returning null .

Try using the absolute path to the file that you want to read, eg

var fis=new Packages.java.io.FileInputStream("/full/path/to/Logs.properties");
