ErrorMsg: AwE-5102 Agent error (10/17/09 5:57 PM)
Details: 49484948[SSL_NULL_WITH_NULL_NULL:  Socket[addr=/,port=45031,localport=49155]] no cipher suites in common

There are many different algorithms which can be used for encrypting data, and for computing the message authentication code.  Some provide the highest levels of security, but require a large amount of computation for encryption and decryption; others are less secure, but provide rapid encryption and decryption.  The length of the key used for encryption affects the level of security - the longer the key, the more secure the data.

To allow users to select the level of security that suits their needs, and to enable communication with others who might have different security requirements, SSL defines cipher suites, or sets of ciphers.  When an SSL connection is established, the client and server exchange information about which cipher suites they have in common.  They then communicate using the common cipher suite that offers the highest level of security.  If they do not have a cipher suite in common, then secure communication is not possible.

Install a client server java which shares a common cipher suite.  Contact Automic Support for a workaround.
