generate Admin cert throwing error

[shankarjai2525]

hi,
After setting up the bluemix blockchain application, changed the following variables
public static final String NETWORK_CONFIG_PEERORG_CA = "org1-ca";
public static final String NETWORK_CONFIG_PEERORG = "org1-peer1";
public static final String TEST_CHANNEL = "defaultchannel";
I ran the following command from the maven project
mvn exec:java -Dexec.mainClass="org.cr22rc.BMXHyperledgerFabricJSDKIntegrationSample"

This is the error I got.
mvn exec:java -Dexec.mainClass="org.cr22rc.BMXHyperledgerFabricJSDKIntegrationSample"
