[Ikvm-developers] Am I doing this right

[Graham O. <gra...@on...>]

Hi Team

 

I have written a program using the Cisco API for the Call Manager phone
system. The API comes as a jtapi.jar

 

I have converted the jtapi.jar to a jtapi.dll and my program works
great.

 

The problem I have is that there are lots of versions of Call Manager
and you have to use the matching jtapi.jar file, so I was looking into
loading the jtapi.jar at run time then I can just load whatever version
is installed.

 

These are from VS2010 so using the dll I have this

 

try

{

      CiscoJtapiVersion jv = new CiscoJtapiVersion();

      label1.Text = jv.getVersionName();

      label2.Text = jv.getVersion();

      label3.Text = jv.getMinorVersion().ToString();

      label4.Text = jv.getMajorVersion().ToString(); 

}

catch (Exception ex)

{

       label4.Text = ex.Message;

}

 

 

And loading at Run Time I have this:

 

// Create a URL instance for every jar file that you need

java.net.URL url = new
java.net.URL("file:C:\\Windows\\Java\\lib\\jtapi.jar");

// Create an array of all URLS

java.net.URL[] urls = { url };

// Create a ClassLoader

java.net.URLClassLoader loader = new java.net.URLClassLoader(urls);

try

{

      // load the Class

      java.lang.Class cl = java.lang.Class.forName("CiscoJtapiVersion",
true, loader);

      // Create a Object via Java reflection

      Type type = ikvm.runtime.Util.getInstanceTypeFromClass(cl);

 

      dynamic jv = type.GetConstructor(new Type[] { }).Invoke(null);

      label1.Text = jv.getVersionName();

      label2.Text = jv.getVersion();     

      label3.Text = jv.getMinorVersion().ToString();

      label4.Text = jv.getMajorVersion().ToString();

}

catch (Exception ex)

{

       label4.Text = ex.Message;

}

 

My question is: 

 

Am I going about this the right way?

 

I assume I need to define all my objects as dynamic as there is no way
of getting a static reference

 

Defining the objects as dynamic makes it a bit unforgiving of any typo's
etc.

 

Thanks
