Access host variable from servlet

[Nathan Maves]

Is this possible?  I have a custom email servlet and I would love to pull a host variable from the servlet.

use the HostVariableAPI and the COntentAPI to get what you need.

Are you suggesting using the restful API for this? or the straight Java API?

Sorry I has taken me so long to get back to this thread.

Below is what I have in my Servlet.  My issue is that I don't know how to pull the current host/user that is making the request?  For a little more background this is a Servlet that handles form submissions and emails them via Amazon's Simple Email Service (SES).

final HostAPI hostAPI = APILocator.getHostAPI();

final HostVariableAPI hostVariableAPI = APILocator.getHostVariableAPI();

final ContentletAPI contentletAPI = APILocator.getContentletAPI();

hostVariableAPI.getVariablesForHost(hostId, user, respectFrontendRoles);

I tried this approach but I am getting the following exception.  My code is below the exception as well.  How with this code know which host to pull the variables from?  I need the servlet to pull a host variable for each host I have when they submit to the servlet.

Here is the code I am using to pull the host variables.

// User to check in as

User user = APILocator.getUserAPI().getSystemUser();

// respect CMS Anonymous permissions

boolean respectFrontendRoles = false;

// Host on which to place the content

Host host = APILocator.getHostAPI().findDefaultHost(user, respectFrontendRoles);

final List<HostVariable> variablesForHost = APILocator.getHostVariableAPI().getVariablesForHost(host.getInode(), user, respectFrontendRoles);

String to = null;

for (HostVariable hostVariable : variablesForHost) {

if (hostVariable.getKey().equalsIgnoreCase("contactEmail")) {

to = hostVariable.getValue();

}

}

This error can be fixed by using host.getIdentifier() not host.getInode() on this line:

final List<HostVariable> variablesForHost = APILocator.getHostVariableAPI().getVariablesForHost(host.getIdentifier(), user, respectFrontendRoles);
