i developing java application , using javamail send mail. code following:

however when execute code throws exception:

javax.mail.messagingexception: not connect smtp host: diana.cartif.es, port: 465, response: -1     @ com.sun.mail.smtp.smtptransport.openserver(smtptransport.java:1960)     @ com.sun.mail.smtp.smtptransport.protocolconnect(smtptransport.java:642)     @ javax.mail.service.connect(service.java:317)     @ javax.mail.service.connect(service.java:176)     @ javax.mail.service.connect(service.java:125)     @ javax.mail.transport.send0(transport.java:194)     @ javax.mail.transport.send(transport.java:124)     @ com.cartif.data.mainconnection.getftpconnection(mainconnection.java:106)     @ com.cartif.main.main.connecttoserver(main.java:72)     @ com.cartif.main.main.main(main.java:60)
