Java Security

I am making a "secure" chat server that has some simple functionality.

For the server cert, I sent off the CSR to Thawte and set up the trust chain. That keystore seems to be fine:

Keystore type: jks
Keystore provider: SUN

Your keystore contains 2 entries

So next I want to set up my client. The professor said that it's fine to just give the clients all self-signed certs, so I ran:
keytool -genkey -alias client1 -keyalg RSA -keystore c1keystore -storepass client1 -keypass client1 -dname "o=jhu, cn=Client 1"

I assumed that I need to add the Thawte Root CA Cert to this keystore as well since I'm doing client authentication:
keytool -import -v -file ../server/thawtecert.txt -trustcacerts -keystore c1keystore -storepass client1

I start up the server, and then I attempt to connect with the client with these options:
-Djavax.net.ssl.trustStore=server/serverstore
-Djavax.net.ssl.keyStore=client/c1keystore
-Djavax.net.ssl.keyStorePassword=client1

Now when I attempt to connect to the server and write to the buffer, I get this error on the client side:
javax.net.ssl.SSLHandshakeException: Received fatal alert: bad_certificate

And this error on the server side:
javax.net.ssl.SSLException: Connection has been shutdown: javax.net.ssl.SSLHandshakeException: null cert chain

If I connect to the server with these options, I connect fine:
-Djavax.net.ssl.trustStore=server/serverstore
-Djavax.net.ssl.keyStore=server/serverstore
-Djavax.net.ssl.keyStorePassword=server

I assume this means that I have done something very wrong creating the client's keystore. Does anyone know how I'm supposed to create it?
