Issues with code that appears to store driver information in memory

Hi, I am new to IKVM.
I am attempting to convert java code that uses a neon jdbc driver to connect to a db2 database.
The ikvm tool does a marvelous job of creating dlls that I can add to my project.
The potential issue appears related to the following java code:
Class.forName(IConnectionConstants.ClassName ).newInstance();

The class name constant value is the name of the neon driver : "com.neon.jdbc.Driver". the
The UrlPrefix is: "jdbc:neon:db2test". Datasource is blank.

The full code is
java

                     //create connection using connection properties
                     Class.forName( IConnectionConstants.ClassName ).newInstance();

                     String url = IConnectionConstants.URLPrefixBatch + IConnectionConstants.DataSource;

                     connect = DriverManager.getConnection( url, IConnectionConstants.UserName, IConnectionConstants.PassWord );
                     setCurrentSQLID(connect);

                     return connect;









As seen above, the call to getConnection does not use the driver name.
In initial attempts, I received an error that db2test could not be found. This is an ODBC dsn, and does exist. I can successfully connect to the database from my C# project.

I tried registering the driver separately

com.neon.jdbc.Driver myDriver = new com.neon.jdbc.Driver();
DriverManager.registerDriver( myDriver );

String url = URLPrefixBatch + DataSource;

connect = java.sql.DriverManager.getConnection( url, UserName, PassWord );

I then get:
          java.lang.UnsatisfiedLinkError
which references:
com/neon/jdbc/ProxyLocal.initenv(IIII)S.

I can see the ProxyLocal class exists in the converted neon dll.
I tried direct calls like:
com.neon.jdbc.ProxyLocal p2 = ProxyLocal.getInstance();
but get the same error.
It seems like it instantiates the driver and puts in memory(?), and then later code (like the ProxyLocal.initenv) grabs it from memory or through some other mechanism.
If the latter is true, I am not sure what the equivalent might be in C#.
Does anyone have suggestions?
