Examples of org.apache.click.util.ErrorPage

org.apache.click.util.ErrorPage
Provides the base error handling Page. The ErrorPage handles any unexpected Exceptions. When the application is not in "production" mode the ErrorPage will provide diagnostic information.
The ErrorPage template "click/error.htm" can be customized to your needs.
Applications which require additional error handling logic must subclass the ErrorPage. For example to rollback a Connection if an SQLException occured:
```
 package com.mycorp.util; import java.sql.Connection; import java.sql.SQLException; import org.apache.click.util.ErrorPage; public class MyCorpErrorPage extends ErrorPage { / * @see Page#onDestroy() * / public void onDestroy() { Exception errror = getError(); if (error instanceof SQLException || error.getCause() instanceof SQLException) { Connection connection = ConnectionProviderThreadLocal.getConnection(); if (connection != null) { try { connection.rollback(); } catch (SQLException sqle) { } finally { try { connection.close(); } catch (SQLException sqle) { } } } } } } 
```
The ClickServlet sets the following ErrorPage properties in addition to the normal Page properties:
- {@link #error} - the error causing exception
- {@link #mode} - the Click application mode
- {@link #pageClass} - the Page class which cause the error
