When you click the "save" button you have to run the "submit" method of the form panel's layout and send your Combobox value inside a parameter, example:

var comboBox = new Ext.form.ComboBox({
    //...
    id: 'comboBox',
    name: 'comboBox'
});

var formPanel = new Ext.form.FormPanel({
    //...
    id: 'formPanel',
    items: [comboBox],
    buttons: [{
        text: 'Submit',
        handler: submitForm
    }]
});

var submitForm = function () {
        var formPanel = Ext.getCmp("formPanel")
        formPanel.form.submit({
            url: example.jsp,
            success: function (form, action) {
                alert("success")
            },
            failure: function (form, action) {
                alert("failure")
            }
        });
    };

Then you can use the comboBox parameter at server-side, it comes in "example.jsp".
