XSA Java Odata v4 not working

[former_member233511]

Hello, I continue to setup different parts of XSA.
Today i struggle with setting up Odata v4 Java module.

Every module builds and run successfully.

My cds top part:

namespace demo_project.db.cds;

@OData.publish : true
context MY_CONTEXT {
	entity EXPAMPLE {

Browser url that i'm using to access OData:

https://my_host_here:51036/java/odata/v4/demo_project.db.cds._.MY_CONTEXT/$metadata

Result "Not Found" page

There is Java errors during start module process, but it still running:

Hello xefimx , pangxixin , sergeyivanovich.pochuhaylov ,

I have the same issue with the Odata 4.0 tutorial. Did someone resolved the issue?

When you create Java app based on the template "ODATA v4 service"m you got the error

You need to create a Java app based on the template "Web application with ODATA v4 support".

Hi Sergey,

But in HANA2.0SP5 this template is not available. Therefore I used the "Odata V4 Service" and get the same error as described.

Regards,

Udo
