Custom OVD Plugin 11g

Question

I have created a plugin according the the notes in metalink and the pdf file attached to the metalink note. The problem I'm having is that after upload of my jar the plugin shows up in the libraries correctly as a plugin but when I go to an adapter and assign the plugin to my db adapter it shows up in the list. Then I click Apply so that it will save the change and I get a java.lang.reflect.InvocationTargetException. I have checked the logs and the only thing I can see is after a reboot the logs show that the import statements I used in my jar file are showing up as unresolved compilation errors for all of the imports and the imports are just the com.octetstring and com.asn1c which already exist in the OVD classpath correct? I have tried to include those jar files into my plugin jar at the root of my jar as well as by putting them in a lib folder. I don't know if I'm missing something with regards to my manifest.mf file but it includes the basics from the vde-properties file referenced in the pdf file explaining how to create the plugin. Can anyone help?

Here is the code. I'm not actually doing anything in the code yet I was just trying to get it loaded to prove that I had the jar setup correctly. So I have a series of system.out.s to check values.
package com.octetstring.vde.chain.plugins;
import com.asn1c.core.Bool;
import com.octetstring.vde.Credentials;
import com.octetstring.vde.chain.Chain;
import com.octetstring.vde.chain.ChainException;
import com.octetstring.vde.chain.PluginInit;
import com.octetstring.vde.syntax.BinarySyntax;
import com.octetstring.vde.syntax.DirectoryString;
import com.octetstring.vde.util.DirectoryException;
public class PRCNGAuthenticate extends com.octetstring.vde.chain.BasePlugin{
     * Passes initialization information to the Plug-in
     * @param initParams
     * Hashmap of key/value pairs specified in initial config
     * @param name
     * The name specified in the config for this Plug-in
     public PRCNGAuthenticate() {
          super();
     * Passes initialization information to the Plug-in
     * @param initParams
     * Hashmap of key/value pairs specified in initial config
     * @param name
     * The name specified in the config for this Plug-in
     @Override
     public void init(PluginInit initParams, String name) throws ChainException {
          //the jURL parameter is required
//     if (!initParams.containsKey(PRCNGAuthenticate.CONFIG_JDBC_URL)) {
//     throw new ChainException(name + ": The "
//     + PRCNGAuthenticate.CONFIG_JDBC_URL
//     + " attribute is required");
//     if (!initParams.containsKey(PRCNGAuthenticate.CONFIG_JDBC_USER)) {
//     throw new ChainException(name + ": The "
//     + PRCNGAuthenticate.CONFIG_JDBC_USER
//     + " attribute is required");
//     if (!initParams.containsKey(PRCNGAuthenticate.CONFIG_JDBC_PWD)) {
//     throw new ChainException(name + ": The "
//     + PRCNGAuthenticate.CONFIG_JDBC_PWD
//     + " attribute is required");
//     this.jURL = new DirectoryString(initParams
//     .get(PRCNGAuthenticate.CONFIG_JDBC_URL));
//     this.jUID = new DirectoryString(initParams
//     .get(PRCNGAuthenticate.CONFIG_JDBC_USER));
//     this.jPWD = new DirectoryString(initParams
//     .get(PRCNGAuthenticate.CONFIG_JDBC_PWD));
//     System.out.println("jURL"+this.jURL);
     }//end of init method
     * Determines if a plugin is available for the current chain
     * @param chain
     * @param base
     * @return True or False if available for a particular chain & base
     public boolean available(Chain chain, DirectoryString base) {
     return true;
     }//end of available method
     * Moves through the "bind" operation's chain
     * @param chain
     * The current chain
     * @param dn
     * The DN for the user
     * @param password
     * The user's password
     * @param result
     * The result of the bind
     @Override
     public void bind(Chain chain, Credentials creds, DirectoryString dn,
     BinarySyntax password, Bool result) throws DirectoryException,
     ChainException {
     System.out.println("CHAIN GETOPTYPE"+chain.getOperationType());
          System.out.println("CREDS GETUSER"+creds.getUser().toString());
          System.out.println("DN"+dn.toString());
          System.out.println("password"+password.toString());
          result.setValue(true);
          chain.nextBind(creds, dn, password, result);
     }//end of bind method
}
