I am having troubles with v4 and adding function libraries.
I have made my java file with all the appropriate functions and implementations and created a jarfile with FATJar (test.jar). I have modified setenv and setenvClient (%AWARE_HOME%\test.jar😉 and BASServer.props (FunctionLibraryTestJAR=test.TestJAR) and I always get unsupported function.

The question I have is what might I be doing wrong?

It appears that awareIM is still unable to recognize my custom library.

The java file looks like this..
package test;

import java.util.Collection;
import org.openadaptor.util.DateTimeHolder;
import com.bas.shared.data.FunctionDescription;
import com.bas.shared.functions.IFunctionLibrary;
import com.bas.shared.ruleparser.INodeHelper;
import com.bas.shared.ruleparser.ISQLBuilderHelper;

public class TestJAR implements IFunctionLibrary
{
/*
* Default constructor, no global variables or settings to worry about
*/
public TestJAR()
{
}

/*
 * Calculate is the name of an expected method by AwareIM 
 * This method declaration may not be changed 
 */
public Object calculate(String arg0, Object[] arg1, INodeHelper arg2)
{	
	
	/* 
	 * Prints incoming arguments to screen, this is a good 
	 * way to check values moving to and from AwareIM 
	 */
	for(int i = 0; i < arg1.length; i++)
	{
		System.out.println(arg1[i].toString());
	}
	
	try 
	{

		if(arg0.compareTo("loi") == 0)
		{

			if(arg1.length != 1)
			{
				return("-1");
			}
			
			
			return ("loi was here");
		}

		else
		{
			return("-2");
		}
	}
	/* Print out caught exception types with errors */
	catch (Exception e) 
	{
		System.out.println(e);
	}
	
	return ("-2");
}

/*
 * EXTRA CODE
 * The following is used for integrating into the wrapper class.
 * */
public FunctionDescription[] getAvailableFunctions() 
{
	FunctionDescription [] description = new FunctionDescription[14];
	description[0] = new FunctionDescription("loi", 
			"Get Test." + 
			"\nParameters:\n- Test Token" + 
			"\nReturns: String");
	
	return description;
}

public String getName() 
{
	return("TestJAR");
}

public Class getTypeClass(String arg0, Collection arg1) 
{
	if(arg0.compareTo("loi") == 0)
	{
		return(DateTimeHolder.class);
	}
	else
	{
		return(String.class);
	}
}

public boolean hasFunction(String arg0, int arg1) 
{
	if(arg0.compareTo("loi") == 0)
	{
		return(true);
	}
	else
	{
		return(false);
	}
}
public String toSQL(String arg0, Collection arg1, ISQLBuilderHelper arg2)
{
	return null;
}

}
