scriptengine

Our project need ability to have a simple business rules our customers can script in Visual basic. While our main program is written on C# The script which customers want to execut could be like this (I am considering the simpliest possible case) var vbCode = @" If (Row.Code = 12) Then Row.MappedCode = 1 End If"; So I created a RowData class in C# with Code and MappedCode properties namespace ScriptModel { public class RowData { public int Code { get; set; } public int MappedCode { get; set; } } } I created a simple host object class like namespace ScriptModel { public class HostObjectModel {

I am trying to send one class through hostObject but apparently it doesn't want to work: using Roslyn.Compilers; using Roslyn.Compilers.CSharp; using Roslyn.Scripting; using Roslyn.Scripting.CSharp; public class ShippingService { public class ShippingDetails//class that I want to send { public decimal total { get; set; } public int quantity { get; set; } public string destination { get; set; } } public static string ShipingCost(decimal total, int quantity, string destination) { var details = new ShippingDetails { total = total, quantity = quantity, destination = destination }; try {

I am trying to use ScriptEngineManager and ScriptEngine to execute some JavaScript code with Java. I use Java 8 I am executing this code under Karaf OSGi. The example I used works fine in a sample Java Class, but packing it in a bundle gives me this error ScriptEngineManager providers.next(): javax.script.ScriptEngineFactory: Provider jdk.nashorn.api.scripting.NashornScriptEngineFactory not found When I look to the headers of the bundle, I see that the bundle imports javax.script, the package of the called classes but it seems that (nashorn) the provider is not found. Thanks Go to file etc

I'm fairly new to Nashorn and scripting on top of the JVM and wanted to know if I can get my java code and javascripts to communicate more effectively. I'm using a 3rd party JS lib that works with JS objects, and in my java code I have the data I want to pass as a Map<String, Object> data . Because that 3rd party JS expects to work with plain JS objects I can't pass my data as is, although the script engine allows you to access a Map as if it was a plain JS object. The script i'm using uses 'hasOwnProperty' on the data argument and fails when invoked on an Java object. When I tried using

I have this Java code which I am using to run a python script using Jython ScriptEngine : StringWriter writer = new StringWriter(); ScriptEngineManager manager = new ScriptEngineManager(); ScriptContext context = new SimpleScriptContext(); context.setWriter(writer); ScriptEngine engine = manager.getEngineByName("python"); engine.eval(new FileReader("/Users/folder1/test.py"), context); In my python script there are several module import statements and when I run the Java code I get error as javax.script.ScriptException: ImportError: No module named psycopg2 . All the modules are installed in my
