I am trying to test the client side security exit on MQ V6 as suggested in http://www-128.ibm.com/developerworks/websphere/library/techarticles/0512_ritchie/0512_ritchie.html. The source code is as follows:
| Code: |
package example;
public class SecurityExit implements com.ibm.mq.MQSecurityExit {
public byte[] securityExit(MQChannelExit channelExitParms,
MQChannelDefinition channelDefParms,
byte[] agentBuffer) {
switch (channelExitParms.exitReason) {
case MQC.MQXR_INIT:
// initialize etc.
break;
case MQC.MQXR_INIT_SEC:
// transmit MCAUserId if desired etc.
break;
case MQC.MQXR_SEC_PARMS:
// create a new MQCSP object
MQConnectionSecurityParameters csp = new MQConnectionSecurityParameters();
// set authenticationType to AUTH_USER_ID_AND_PWD
csp.setAuthenticationType(MQC.MQCSP_AUTH_USER_ID_AND_PWD);
// set CSP UserId and password from the JMS-supplied values
csp.setCSPUserId(channelDefParms.remoteUserId.trim());
csp.setCSPPassword(channelDefParms.remotePassword.trim());
// finally add MQCSP object to the channelExitParms
channelExitParms.setMQCSP(csp);
break;
case MQC.MQXR_TERM:
// etc.
}
return agentBuffer;
}
} |
But when I try to run the Java client, I got the following exception:
| Code: |
Linked exception: java.lang.NoSuchMethodException: SecurityExit.<init>(java.lang.String)
javax.jms.JMSException: MQJMS1009: no constructor with string argument

Anyone see this problem before? I have no idea which method is missing.
Thanks a lot,

Thanks for the quick response. The code is something like this:
MQQueueConnectionFactory mqcf = new MQQueueConnectionFactory();
mqcf.setHostName("localhost");
mqcf.setChannel("SYSTEM.DEF.SVRCONN");
mqcf.setSecurityExit("SecurityExit");
QueueConnectionFactory cf = (QueueConnectionFactory) mqcf;
QueueConnection qc = cf.createQueueConnection("testuser", "secret");
...
After some trial and error, I have added a contructor:
public SecurityExit(String key) {
}
It fixed the exception and everything is OK. Looks like the contructor requires the String as the only argument.
This one only works for MQ V6. I am not able to compile it on MQ V5.3, though.
Thanks,
Yannan |
