-## Example
-
-Here we will show how to use Java SDK for Boston house price prediction. Please refer to [examples](../java/examples) folder for more examples.
-
-### Get model
-
-```shell
-wget --no-check-certificate https://paddle-serving.bj.bcebos.com/uci_housing.tar.gz
-tar -xzf uci_housing.tar.gz
-```
-
-### Start Python Server
-
-```shell
-python -m paddle_serving_server.serve --model uci_housing_model --port 9393 --use_multilang 
-```
