HI to All,
I have a simple flow mqinput->compute->mqoutput
Compute node calls a JAVA function xyz which calls LoadProperties function to load data from File_resources.properties (in JAVA project: config and bin directories) as a ResourceBundle.
Changing values on File_resources file does not take effect (in debugger testing) unless bar is regenerated.
File_resources.properties file is not included in BAR.
public static Vector<mydata> LoadProperties()
{
ResourceBundle rb = ResourceBundle.getBundle("File_resources");
Enumeration <String> keys = rb.getKeys();
Vector<mydata> _mydata = new Vector<mydata>();
String[] IpPort;
while (keys.hasMoreElements()) {
String key = keys.nextElement();
String value = rb.getString(key);
...
...
...
}
return _mydata;
}
here is File_resources:
node1=xxx
node2=yyy
How can i get the new changes loaded in run time (and debugger time) without rebuilding bar?
any ideas? |

You mean for every MQ message, you're going to read properties ? Whats wrong with UDPs? What does this help you do that you cannot do with UDPs or BFOs?

This eventually will change to STATIC.
also there are many key=value elements. UDP would not name it.
How can ResourceBundle be refreshed without rebuild/deploy bar ? |

Use HashMap and have it be maintained by a constructor of a Java object that gets called at EG start time or when manually invoked by a utility function.
You seem to be reinventing the wheel. If you are on V8+, you should be using the global cache to do what you are doing.
You can reload the global cache objects any time you want.
Why custom code all the things that global cache gives you ?

| Why use global cache or a properties file when you can use User Defined Properties? |

How often do you change the values in the properties file?

Using UDP is the best approach for this and that is the purpose of UDP's. If you still feel hard to maintain the Key-Value pairs in UDP, you can go for SHARED variables and have a logic to flush them every time a update is made on the properties file. Do Not CALL a Java function for every message. |

| V 8 User Defined Configurable Services are refreshed automatically. No need to cache the data. |
