Create 3 new *.ds.xml files:


Code Block
langxml
titleusers.ds.xml
langxml
<DataSource
    ID="users"
    serverConstructor="com.smartgwt.sample.server.UsersDataSource"
>
    <fields>
        <field name="userName"        type="text"  title="User Name"      primaryKey="true" />
    </fields>
</DataSource>



Code Block
langxml
titleroles.ds.xmllangxml
<DataSource
    ID="roles"
    serverConstructor="com.smartgwt.sample.server.RolesDataSource"
>
    <fields>
        <field name="roleName"  	type="text"      title="Role Name" primaryKey="true"/>
    </fields>

</DataSource>



Code Block
langxml
titleusersRoles.ds.xml
langxml
<DataSource
    ID="usersRoles"
    serverConstructor="com.smartgwt.sample.server.UsersRolesDataSource"

    <fields>
        <field name="userName"  	type="text"      title="User Name" primaryKey="true"/>

    </fields>

    <operationBindings>

        <operationBinding operationType="remove"

For this example,  use the supplyItem.ds.xml file:


Code Block
lang
langxml
titlesupplyItem.ds.xmlxml
<DataSource
    ID="supplyItem"
    recordXPath="/List/supplyItem"
    dataURL="ds/test_data/supplyItem.data.xml"

    <fields>
        <field name="itemID"      type="sequence" hidden="true"       primaryKey="true"/>
        <field name="itemName"    type="text"     title="Item"        length="128"       required="true"
        	   editRequiresRole="admin" />
        <field name="SKU"         type="text"     title="SKU"         length="10"        required="true"

While the user is being re-authenticated, the requested operation is put on hold. If the re-authentication is successful, the operation on hold, is released and continues as normal.

Note: We have seen some installations of JDBC Realms where the following request is required, or the system would not accept credentials submitted by the relogin form:

Code Block
languagejava
RPCRequest request = new RPCRequest();
request.setActionURL("loginSuccessMarker.html");
RPCManager.sendRequest(request);

You can find more information relating to the re-login mechanism here.
