OPENSHIFT + j_security_check problems - openshift

Question

I have Java code with j_security_check that works on a local Tomcat + MySQL server. I am not able to get it working on the Openshift Jboss (Tomcat) cartridge.
----web.xml code snippet:----
<security-constraint>
<web-resource-collection>
<web-resource-name>Validate</web-resource-name>
<url-pattern>/user/*</url-pattern>
<http-method>POST</http-method>
<http-method>GET</http-method>
</web-resource-collection>
<!-- Authorize the service and programmer roles -->
<auth-constraint>
<role-name>user</role-name>
</auth-constraint>
</security-constraint>
<!-- Use form-based authentication to provide access -->
<login-config>
<auth-method>FORM</auth-method>
<form-login-config>
<form-login-page>/validation/login.jsp</form-login-page>
<form-error-page>/validation/login_error.jsp</form-error-page>
</form-login-config>
--------META-INF/context.xml:-----
<Context path="/musicStoreOTUser">
<Resource auth="Container"
driverClassName="com.mysql.jdbc.Driver"
logAbandoned="true"
maxActive="100"
maxIdle="30"
maxWait="10000"
name="jdbc/musicDB"
password="ask4_sgh"
removeAbandoned="true"
removeAbandonedTimeout="60"
type="javax.sql.DataSource"
url="jdbc:mysql://127.7.245.2:3306/mydb"
username="admin1234"/>
<Realm className="org.apache.catalina.realm.JDBCRealm"
connectionName="admin1234"
connectionPassword="ask4_sgh"
connectionURL="jdbc:mysql://127.7.245.2:3306/mydb"
dataSourceName="jdbc/musicDB"
debug="99"
driverName="com.mysql.jdbc.Driver"
roleNameCol="Rolename"
userCredCol="Password"
userNameCol="EmailAddress"
userRoleTable="RoleTable"
userTable="PassTable"/>
When I log in in the login form, I simply get Login incorrect. No messages are logged in the jbossews.log file.
Appreciate any thoughts.
Thanks,
