connector error:somebody help me #131

Open kimakuma opened 2 years ago

kimakuma commented 2 years ago

Please understand that my English is weak rti is in progress with python. The "simple" example ran without problems. However, I want to experience the idl and qos changes, so I am printing "helloworld".

After creating a file for helloworld with idl, I changed it to xml. And proceeded according to all the references. There seems to be nothing different from the simple example code. But the following error pops up why?

Hey @kimakuma Can you share the XML file with me? It looks like Connector is failing to parse it for some reason.

Here is my xml file. However, it may have changed slightly from before. but the error is the same Thanks for reading my post and replying

<?xml version="1.0" encoding="UTF-8"?>

@kimakuma Thanks. So I can see a few things:

  1. Looks like you are missing the top level dds XML tags (e.g.: https://github.com/rticommunity/rticonnextdds-connector-py/blob/master/examples/python/ShapeExample.xml#L10).
  2. I don't see a the type definition in the XML, it should have been generated within a <types> XML tag (e.g.: https://github.com/rticommunity/rticonnextdds-connector-py/blob/master/examples/python/ShapeExample.xml#L27).
  3. I don't think the syntax you are using to set reliability/durability is valid. The QoS policies need to be within their corresponding tags (e.g.: https://github.com/rticommunity/rticonnextdds-connector-py/blob/master/test/xml/TestConnector.xml#L32).

Hope that helps.
