> Hi,
> I have successfully setup Apache configuration to read from a database table by using
DatabaseConfigurationProvider. However when I change the database property in the DB table
and read the property again, it always has the previous value and not the updated value from
Table.
> My code is:
> {quote}
> *Setup:*
> 			DefaultConfigurationBuilder builder = new DefaultConfigurationBuilder(propFileUrl);
> 			DefaultConfigurationBuilder.ConfigurationProvider provider = new DatabaseConfigurationProvider();
> 			builder.addConfigurationProvider("database", provider);
> 			ReloadingStrategy strategy = new FileChangedReloadingStrategy(); 
> 			((FileChangedReloadingStrategy) strategy).setRefreshDelay(5000);
> 			builder.setReloadingStrategy(strategy);			
>                         combinedConfig = builder.getConfiguration(true);
> *Config.xml:*
>                          <configuration>
>                          <database jndi="jdbc/semsDs" table="CSW_APPL_PROPERTIES"
keyColumn="PROP_NAME" valueColumn="PROP_VALUE"/>
>                          </configuration>
> *To access table property:*
> String dbProp = combinedConfig.getString("TEST_PROP");
> {quote}
> *Steps to recreate:*
> 1) Setup Apache database configuration as above.
> 2) Access the property from DB table TEST_PROP=TEMP_1
> 3) Now change the TEST_PROP value to TEMP_2 in the DB table.
> 4) Access the property from  the same DB Table.
> 5) Property Value still says TEMP_1.
