Keystore Problem: Cannot convert COMBINED of type class java.lang.String to class org.jivesoftware.o

go to: Server Manager -> System Properties Search for "xmpp.socket.ssl.client.keypass" Make sure its right and it should fix your problem if you are using the default files make sure its value is “changeit” 





xmpp.socket.ssl.active 	true 	
xmpp.socket.ssl.client.keypass 	
xmpp.socket.ssl.client.keystore 	/opt/openfire/resources/security/keystore 	
xmpp.socket.ssl.client.trustpass 	
xmpp.socket.ssl.client.truststore 	/opt/openfire/resources/security/truststore 	
xmpp.socket.ssl.keypass 	
xmpp.socket.ssl.keystore 	resources/security/keystore 	
xmpp.socket.ssl.trustpass 	
xmpp.socket.ssl.truststore 	resources/security/truststore 


有关路径：留空的话，系统会选择默认路径。能够填写相对路径(相对于安装目录)，也能够选择绝对路径
