Reading the java library path

Classic Servoy
1

Hi All

Is there a possibility to read the java library path within Servoy, i. e. in a Servoy module? Something like the eqivalent of System.getProperty(“java.library.path”) in Java?

You can use java code directly in Servoy:

application.output(java.lang.System.getProperty("java.library.path"))

To supplement Patrick’s reply here is a function that I use to figure out all properties:

function getSystemProperties() {
	/** @type {java.util.Properties} */
	var props = java.lang.System.getProperties();//Properties object returned
	/** @type {java.util.Enumeration} */
	var enumeration = props.propertyNames();
	
	while (enumeration.hasMoreElements()){
		/** @type {String} */
		var prop = enumeration.nextElement();
		application.output('property: ' + prop);
	}
	/** @type {String} */
	var libPath = java.lang.System.getProperty('java.library.path');
	var array_libPath = libPath.split(';');
	for (path in array_libPath){
		application.output('library path[' + path + '] = ' + array_libPath[path]);
	}
	return;
}

Hi,

small change :

If you replace

application.output('property: ' + prop);

by

application.output('property: ' + prop + ' = ' + java.lang.System.getProperty(prop));

it will not just show the key, but also the value of that key

Thanks a lot to all of you for the quick reply, that helped a lot in tracking down the problem of not being able to use the SQL Anywhere JDBC4 driver sajdbc.jar, but being able to use the jconn3.jar driver.
