Hi Linda,

I can compile it fine with your example. Steps I followed:

1. Add the assembly reference to System.Configuration.dll to the project references.
2. Add a "using System.Configuration" to the top of the class.

Then you should be able to use the ConfigurationManager class as follows:

string executableString = System.Configuration.ConfigurationManager.AppSettings.Get("javaExecString");
string parametersString = ConfigurationManager.AppSettings.Get("javaParamString"); 
string serverString = ConfigurationManager.AppSettings.Get("javaServerString");
