DynamicDSGenerator: getServerName()

[pavo123]

Hi Isomorphic,

can you please help me with this.

Is it possible to get "server name" inside of DynamicDSGenerator constructor in case when dsRequest is null?

        DynamicDSGenerator aggTableGenerator = new DynamicDSGenerator() {
            @Override
            public DataSource getDataSource(String id, DSRequest dsRequest) {
                DataSource ds = null;
                try {
                String serverName = null;
                if (dsRequest != null && dsRequest.getHttpServletRequest() != null)
                    serverName=dsRequest.getHttpServletRequest().getServerName();
                else
                    // need some other way
                } catch (Exception ex) {
                    ex.printStackTrace();
                }
                return ds;
            }
        };

Best regards
Pavo

If there is no request that means the DS is being used in a static context so no httpServletRequest is available.

However if server name doesn’t change in your deployment, you can simply store it statically and access it statically.

The server name changes, that's the biggest problem.
With "server name" criteria I fetch data from DB and depending on that data modify datasources.
Now I have that data in customer ".properties" file, but we have to get rid of all customer ".properties" files because of many reasons.

If ServletContext is always available

ServletContext servletContext = getServletContext();

so why not to have server name always available?

This is very important to me, every help is welcome.

That’s what we told you to do. As long as the serverName doesn’t change *per-request* you can access it statically.
