Multiple Data Provides

[Mone]

hi,

you can use multiple .net data adapters within a single adapter set. You just have to configure the adapters.xml correctly so that it can connect to your remote .net adapters.

e.g.:
<?xml version="1.0"?> <br /> <br /> <adapters_conf id="PROXY_HELLOWORLD"> <br /> <br /> <metadata_provider> <br /> <adapter_class>com.lightstreamer.adapters.metadata .LiteralBasedProvider</adapter_class> <br /> </metadata_provider> <br /> <br /> <data_provider name="adapter1"> <br /> <adapter_class>com.lightstreamer.adapters.remote.d ata.NetworkedDataProvider</adapter_class> <br /> <param name="request_reply_port">6661</param> <br /> <param name="notify_port">6662</param> <br /> </data_provider> <br /> <br /> <data_provider name="adapter2"> <br /> <adapter_class>com.lightstreamer.adapters.remote.d ata.NetworkedDataProvider</adapter_class> <br /> <param name="request_reply_port">6663</param> <br /> <param name="notify_port">6664</param> <br /> </data_provider> <br /> <br /> </adapters_conf>
note the name property of the <data_provider> element

obviously you have to configure your second data adapter to use port 6663 and 6664 instead of using 6661 and 6662.

From a client point of view you must now set the adapter name to receive data from the desired data adapter:
var page = new PushPage();<br /> page.onEngineCreation = function(engine) {<br /> engine.connection.setAdapterName("HELLOWORLD");<br /> engine.changeStatus("STREAMING");<br /> }<br /> page.bind();<br /> page.createEngine("HelloWorldApp", "LS", "SHARE_SESSION");<br /> <br /> var pushtable = new OverwriteTable(null, null, "MERGE");<br /> pushTable.setDataAdapter("adapter1");<br /> page.addTable(pushtable, "hellotable");
note the setDataAdapter call

hope that helps
