How to test Crash with this application ?

76 |
77 |
78 |

Here is the step you have to do for connecting Crash to this demo application.

79 |
    80 |
  1. Connect crash on this JVM
    2. 81 |

    82 | %telnet 5000 localhost
    83 | %ssh -p 2000 -l admin localhost (mdp admin)
    84 | 85 | $JDK_HOME/bin/jps and get the id.
    86 | %cd $CRASH_HOME/bin
    87 | %./crash.sh ID

    88 |
  2. Execute the following command :

    % spring_cache showcache

    3. 89 |
  3. Add a Customer with this web interface : Add a customer
    4. 90 |
  4. Execute the spring_cache command again :

    spring_cache showcache

    5. 91 |
