Create a Java Client with mps error 404

When I look at the official document - "MATLAB® Production Server ™ client using the Java® client API", when I implement this code, eclipse told me that there is a mistake, but I have nothing to do with this error;

This is a link to the document:https://cn.mathworks.com/help/mps/qs/create-a-java-application-that-calls-the-deployed-function.html

The error code is "com.mathworks.mps.client.MWHttpException: Failed HTTP request; Response Status: 404, Response Message: ComponentNotFound Component not found. (request id=0:1:0)"

and my operating system is openSUSE 42.2, jdk version is 1.7，MATLAB Production Server version is R2016b

ComponentNotFound means the specified URL (<http://localhost:9910/addmatrix>) does not match the MPS component address.

Could you confirm your deployed addmatrix CTF is starting on MPS with port number 9910?

Answer 2

[aaaa]

I have the same problem even in MPS

[Kojiro Saito]

Please confirm you CTF file name it the same as the archive name in URL.

For example, if your CTF name is addmatrix.ctf,

The URL to access from MPS client (client.createProxy) should be

http://localhost:9910/addmatrix

I did tha same but still not working.

Could you confirm whether you can access MPS by curl command?

If you're using Windows machine, you need to download curl exe from here and please do the following in Command Prompt.

curl -v -H "Accept: application/json" -H "Content-type: application/json" -X POST http://localhost:9910/addmatrix/addmatrix -d "{\"nargout\":1, \"rhs\":[[[1,2,3],[3,2,1]],[[4,5,6],[6,5,4]]], \"outputFormat\":{\"mode\": \"small\"}}"

If you're using Linux machine, please do the following in Terminal.

curl -v -H "Accept: application/json" -H "Content-type: application/json" -X POST http://localhost:9910/addmatrix/addmatrix -d '{"nargout":1, "rhs":[[[1,2,3],[3,2,1]],[[4,5,6],[6,5,4]]], "outputFormat":{"mode": "small"}}'

If the above curl command returns {"lhs":[[[5,7,9],[9,7,5]]]}, MPS connection is OK and the root cause would be Java side.
