Java Primefaces Connection error

I am using primefaces for the development of an application, when it comes to testing on my local server everything works ok, but when I upload it to tomcat and log in to the application it generates this error

This is my context file

<Resource   name="jdbc/xxx"
            auth="Container"
            factory="com.zaxxer.hikari.HikariJNDIFactory"
            type="javax.sql.DataSource"
            minimumIdle="5"
            minPoolSize = "3"
            maximumPoolSize="10"
            connectionTimeout="300000"
            driverClassName="net.sourceforge.jtds.jdbc.Driver"
            jdbcUrl="jdbc:jtds:sqlserver://xxxx;databaseName=xx;instance=xxx;sendStringParameterAsUnicode=false;prepareSQL=2;"
            dataSource.implicitCachingEnabled="true"
            dataSource.user="xxx"
            dataSource.password="xxx"
            connectionTestQuery="Select 1"
/>

That I could be generating this error
