Admin Console

The Admin Console allows you to configure database access for DataSources that use Smart GWT's built-in SQL engine. You can either use the Admin Console UI (as explained below) or directly specify equivalent properties in your server.properties file (see "Manually specifying.." below).

To use the Admin Console, make sure you have followed the full installation instructions - double check that you have the correct GWT <inherits> as shown in those instructions. Then, launch your GWT project from your IDE, and open a web browser to moduleBaseURL/tools/adminConsole.jsp. For example, if you load your application by going to a URL that ends in builtinds/builtinds.html, the correct URL for the Admin Console is builtinds/tools/adminConsole.jsp.

If it's not clear what URL to use, you can add the following code to your onModuleLoad() method to create a button that opens the Admin Console:

    IButton adminButton = new IButton("Admin Console"); 
    adminButton.addClickHandler(new ClickHandler() { 
      public void onClick(ClickEvent event) { 
        com.smartgwtee.tools.client.SCEE.openDataSourceConsole(); 
      } 
    }); 
    adminButton.draw();
  
NOTE: if you are using Pro Edition, the method to call is com.smartgwtpro.tools.client.SCPRO.openDataSourceConsole(), and for Power Edition, com.smartgwtpower.tools.client.SCPower.openDataSourceConsole(). Having opened the Admin Console, available JNDI connections will be discovered and shown automatically. If you aren't using JDNI, use the GUI to enter and test JDBC settings. Both ConnectionManager and JDBC DataSource settings are supported. Once you've got a working connection, set it as the default connection using the "Set as Default" button.

These settings will be written to server.properties in your deployment directory - use the "Download server.properties" button to download the settings and merge them to the server.properties file in your Eclipse (or other IDE) project.

Test Data

You can create a test file that contains a sample dataset which can be imported into your database table with the Admin Console.

The test file to use with your DataSource is specified in the testFileName DataSource configuration property. The test file uses the extension .data.xml.

The test data file should consist of a top-level <List> element containing a series of XML elements named after your DataSource's ID, each of which creates one DataSource record. Values for each field are given within tags named after the field name.

For example, the following XML is from the supplyItem.data.xml test data file supplied with the Isomorphic Smart GWT package. This file is located in [webroot]/examples/shared/ds/test_data/.

Data for a tree-like DataSource can be specified with the same format. The following code example is from the supplyCategory.data.xml test data file. This file is also located in [webroot]/examples/shares/ds/test_data/.
  <List>
      <supplyCategory>
       <itemName>Office Paper Products</itemName>
       <parentID>root</parentID>
      </supplyCategory>
      <supplyCategory>
       <itemName>Calculator Rolls</itemName>
       <parentID>Office Paper Products</parentID>
      </supplyCategory>
      <supplyCategory>
       <itemName>Adding Machine/calculator Roll</itemName>
       <parentID>Calculator Rolls</parentID>
      </supplyCategory>
      . . .
  </List>
  
Notice that all records must define values for the itemName primary key field and for the parentID field that establishes the tree relationship.


Manually specifying database connection settings

The Admin Console maintains settings in the server.properties file, found in your application's WEB-INF/classes directory. If you prefer, you can maintain these settings by directly editing that file. You should restart your servlet engine after changing this file.

For example, the following settings are the defaults in a new Smart GWT installation for a MySQL server; they are approximately correct for a MySQL server running on the same machine as the servlet engine and listening on the default MySQL port. For details of what each of these properties means, check this page.

    sql.Mysql.database.type: mysql
    sql.Mysql.database.ansiMode: false
    sql.Mysql.interface.type: dataSource
    sql.Mysql.driver: com.mysql.jdbc.jdbc2.optional.MysqlDataSource
    # name of the database to use
    sql.Mysql.driver.databaseName: isomorphic
    # hostname and port where the database server is installed
    sql.Mysql.driver.serverName: localhost
    sql.Mysql.driver.portNumber: 3306
    # username and password that can create and modify tables in that database
    # this user must have the following privileges for the system to function
    # properly: create/alter/drop table; insert/update/replace/delete rows.
    sql.Mysql.driver.user: root
    sql.Mysql.driver.password: 
  
Note the distinction here between database type and database name. Database type refers to the actual product - Oracle, DB2 or whatever. In the above example, database type is "mysql" (all lowercase) - the value of property sql.Mysql.database.type. Database type is very important. The type of a given database connection dictates whether features like SQL paging and transactions are supported; it even dictates the syntax of the SQL we generate.

Database name is just an arbitrary name for a particular database connection, and it is embedded in the property names immediately after the sql prefix. In this example it happens to be very similar to the database type - "Mysql" as opposed to "mysql" - but in fact the name has no significance and could be any string. When referring to specific database connections in your DataSources with the dbName property, it is the database name you use.

NOTE: It is common for DataSources to not specify dbName. In this case, the default database is used. To specify the default database manually in server.properties, set sql.defaultDatabase, using database name. So, to set our example connection from above as the default:

    sql.defaultDatabase: Mysql
  

Manually specifying JNDI settings

Instead of specifying database connection parameters directly in server.properties, it is possible to connect to a database that is configured as a JNDI resource in your application server. Assume you have an Oracle JNDI resource with the name "jndiTest", configured similar to this in Tomcat:

    <Resource name="jdbc/jndiTest"
                     auth="Container"
                     type="javax.sql.DataSource"
                     driverClassName="oracle.jdbc.driver.OracleDriver"
                     url="jdbc:oracle:thin:@192.168.132.152:1521:xe"
                     username="system"
                     password="manager"
                     initialSize="5"                 
                     maxActive="50" />
  
The minimal set of properties required to create a Smart GWT database connection that attaches to this resource is as follows (Note that the java:comp/env/ prelude in the first line is optional - the server will automatically look there if it can't find the resource in the absolute location)
    sql.myOracleConnection.driver.name: java:comp/env/jdbc/jndiTest
    sql.myOracleConnection.database.type: oracle
    sql.myOracleConnection.interface.type: jndi
