I already gone through following URLs and understand new classloading concept of AS7.1. https://docs.jboss.org/author/display/AS7/How+do+I+migrate+my+application... https://docs.jboss.org/author/display/AS7/How+do+I+migrate+my+application... https://docs.jboss.org/author/display/AS7/Class+Loading+in+AS7 https://docs.jboss.org/author/display/AS7/Class+Loading+in+AS7 https://docs.jboss.org/author/display/AS7/Implicit+module+dependencies+fo... https://docs.jboss.org/author/display/AS7/Implicit+module+dependencies+fo... I am not understanding when all my application jars are kept inside ./WEB-INF/lib folder (i.e. under jboss\standalone\deployments\wfc.ear\wfc.war\WEB-INF\lib folder) then all these jars, (classes in these jars) should be available, and NoClassDefFoundError: Could not initialize class com.kronos.wfc.platform.properties.framework.KronosProperties error should not occur as KronosProperties class is inside platform_properties_framework.jar located in ./WEB-INF/lib folder. In server.log, NoClassDefFoundError for KronosPropertie class(our application class) is occurring while instantiating our filters defined in web.xml. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/728782#728782] Start a new discussion in JBoss AS 7 Development at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
