Hi,

Please could you share some more information about the problem you got with the Python client you have tested?
I.e. whether you are able to open a client session or not or only the data...

Hi Krishna Teja K,

I'm not sure if you've already come across this feature, but maybe it could be useful in your scenario:...

Hi Krishna Teja K,

Sorry but your scenario is not totally clear to me, but have you tried to use removeRow?

Hi Krishna Teja K,


You need to add 'click' in the fieldsList.

Hi Krishna Teja K,

Ok, so we need to understand why your client don't receive the "click" field as expected.
Please could you post here the code lines the client use to subscribe?
Are you able...

Hi Krishna Teja K,

The snippet of code you attached seems correct to me and the onclick should be actually updated.
Could you please try to trace if indeed your page receives the update with the...

Hi zumb001,

The SubscriptionException thorown in the Data Adapter is not notified to the clients; it just causes the clients not to receive data.
This is because we expect that all checks on the...

Hi ManKeer,

In case a subscription is configured to use an Item Group the string representing the group name can have a free format.
But the getItems method must always return the full list of...

Hi ManKeer,

No, it's up to your Metadata (notifyUser method) to detect the case.
In order to kill the old client session you have various options depending on the Lightstreamer version and...

Certainly, since you have added parameters in the `<data_provider>` section, you will need to add code to read and use them. Therefore, in the `init` method of your Data Adapter, you will need to...

Hi Vinayak Singh,

For such a simple example like HelloWorld, the configuration file of the AdapterSet is equally simple, and you can find it described here:...

It means that the Lightstreamer server receives an update from the Data Adapter for an item name that actually doesn't currently have an active subscription for.

Hi ManKeer,

If you are expecting only one client session, there are two strange things that can be inferred from this request list:

1) It seems that there are two streams of parallel requests...

Hi rthompson,

Please consider that the subscription_timeout_millis setting does not apply in case an explicit unsubscribe request has been received for that item.
It applies only in cases where...

Hi ManKeer,

If the delays involve only a subset of the clients and then we can exclude a general problem affecting the whole server you should look for the "NIO write queue" and "NIO write queue...

Hi Vinayak,

No sorry, unfortunately we have no specific documentation.
You should rely on the official exec plugin documentation: https://www.mojohaus.org/exec-maven-plugin/index.html
But you...

Hi Vinayak,

This is the project of a Remote Data Adapter the can be launched stand-alone via maven: https://github.com/Lightstreamer/Lightstreamer-example-StockList-adapter-java-remote

Hi andres1,

We plan to release an official C++ library in the near future, but honestly it's not expected in the very short term.
So at the moment you have to implement the TLCP protocol, at...

Hi Vinayak,

No, unfortunately at the moment there is no any example that launches contextually the server directly from maven.
As said in one of the previous posts, you should create a specific...

Hi Vinayak,

The "Hello World Tutorial - Java Adapter" project target is to create an In-process Data Adapter.
This type of adapters do not provide the possibility of being launched as stand alone...

Hi Vinayak,

With the pom file provided in the Helloworld Java project you can only build the jar of the demo: mvn package.

In order to deploy your jar and run the demo you have to follow the...

Hi Vinayak Singh,

A typical deployment scenario of an application that uses Lightstreamer for real-time data is the one shown here:

Hi Vinayak Singh,

Sorry, but I'm not sure I understand what exactly your needs are.

The minimal command to launch the Ligthstreamer server without use one of our scripts is:
1. Open a command...
