When running your own servlet, you eventually want to access the Domino environment. To do this, some changes has to be made to the HelloVaadin plug-in<\/a>.<\/p>\n

1. Open the „MANFIFEST.MF<\/em>“ and open the „Dependencies<\/em>“ tab<\/p>\n

2. Add the plug-in „com.ibm.osgi.domino.core<\/em>“ to the list of required plug-ins<\/p>\n

\"01<\/a><\/p>\n

\"01<\/a><\/p>\n

\"01<\/a><\/p>\n

Save the „MANIFEST.MF<\/em>“<\/p>\n

3. Now we can use „com.ibm.domino.osgi.core.context.ContextInfo<\/em>“ to access the Domino environment in HelloVaadinUI<\/em><\/p>\n
