| Using multiple containers |
| ----------- |
| |
| Defining multiple containers |
| |
| It is possible to use more that one Tiles container in your application. |
| |
| * Configuration |
| |
| To use an alternate container, you need to override the |
| {{{../../apidocs/org/apache/tiles/startup/AbstractTilesInitializer.html#method_summary}getContainerKey}} |
| method of <<<AbstractTilesInitializer>>> this way: |
| |
| ------------------------------------ |
| public class TestAlternateTilesListener extends AbstractTilesListener { |
| |
| /** {@inheritDoc} */ |
| @Override |
| protected TilesInitializer createTilesInitializer() { |
| return new TestAlternateTilesInitializer(); |
| } |
| |
| /** |
| * Test Tiles initializer for Tiles initialization of the alternate container. |
| */ |
| private static class TestAlternateTilesInitializer extends AbstractTilesInitializer { |
| |
| // Other customizations go here. |
| |
| /** {@inheritDoc} */ |
| @Override |
| protected String getContainerKey( |
| TilesApplicationContext applicationContext) { |
| return "myContainerKey"; |
| } |
| } |
| } |
| ------------------------------------ |
| |
| Selecting one non-default container |
| |
| Once defined, it is possible to select a non-default container through Java |
| or JSP |
| |
| * Selection through Java |
| |
| It is possible to use, for the current request, a different container |
| stored under another key, by using |
| {{{../../apidocs/org/apache/tiles/access/TilesAccess.html#method_summary}<<<setCurrentContainer>>>}} |
| method of TilesAccess class. For example: |
| |
| ------------------------------------ |
| TilesAccess.setCurrentContainer(request, applicationContext, "myContainerKey"); |
| ------------------------------------ |
| |
| If the last parameter is <<<null>>>, the default container is selected. |
| |
| * Selection through JSP |
| |
| The current container can be selected also through the use of JSP: |
| |
| ------------------------------------ |
| <tiles:setCurrentContainer containerKey="myContainerKey" /> |
| ------------------------------------ |
| |
| If the <<<containerKey>>> attribute is not present, the default container is selected. |
