[opencms-dev] Access to CmsObject from Spring controller

[Steve Bryan]

Thanks Florian, that's much nicer. The required OpenCmsCore methods
getInstance and initCmsObjectFromSession are protected, so can be accessed
from the custom class in the same package!

Perhaps Jonathan's code needed to be in OpenCmsCore because he also accessed
a private method.

I think you don't need to patch for many cases. It should be enough to
create a class in your project that is inside the package
org.opencms.main. This is what I am using:

package org.opencms.main;

import javax.servlet.http.HttpServletRequest;

import org.opencms.file.CmsObject;

/**
 * Provides methods from the OpenCms core that can't be accessed outside
of the package.
 *
 * @author  Florian Hopf, Synyx GmbH & Co. KG, hopf at synyx.de
 */
public class OpenCmsCoreAccessImpl implements OpenCmsCoreAccess {


    public CmsObject initCmsObject(HttpServletRequest request) throws
CmsException {

        return OpenCmsCore.getInstance().initCmsObjectFromSession(request);
    }
}

Not sure if this will work for all cases, but it should if you
additionally use the OpenCms login mechanism which makes sure that the
session is initialized correctly.

Florian
