When I try to subscribe to a Lightstreamer adapter, using a java client, I get the following error
com.lightstreamer.ls_client.PushConnException: java.io.IOException: Server returned HTTP response code: 500 for URL:

Can someone please tell me what I need to do to resolve this?
The client code is as follows
LSClient client = new LSClient();
new ExtendedTableInfo(subscriptions, "MERGE", config.getString("ls.schema").split(" "), true) {
{
setDataAdapter(config.getString("ls.dataAdapter"));
if (config.getBoolean("ls.unfiltered", false)) {
logger.info("RT Unfiltered = true");
requestUnfilteredDispatching();
} else {
logger.info("RT Unfiltered = false");
}
}
}, new HandyTableListener() {
@Override
public void onUpdate(int itemPos, String itemName, UpdateInfo update) {
logger.info(String.format("RT onUpdate, itemPos:%d itemName:%s snapshot:%s", itemPos,
itemName, update.isSnapshot()));
}
