Using Spring boot JMS to send and receive messages over IBM MQ - spring-boot

Following instructions provided in https://developer.ibm.com/tutorials/mq-jms-application-development-with-spring-boot/, I developed a sample Spring boot web application in order to be able to send and receive messages over IBM MQ using JMS template.
In case of a MQ server not on local host, I updated the application.properties file with:
ibm.mq.conn-name=<my-server-host-name>(<my-server-port>)
Unfortunately this is not the appropriate property as the application is searching for a queue manager on localhost.
I did not find in the documentation anything about the property to use for that. And yes, I gave a try to ibm.mq.host and ibm.mq.port.

For IBM config you need to provide the following properties:
Yml extension:
ibm:
mq:
queueManager: {queueManagerName}
channel: {channelName}
connName: localhost(1415)
user: {UserName}
property extension:
ibm.mq.queueManager={queueManagerName}
ibm.mq.channel={channelName}
ibm.mq.connName=localhost(1415)
ibm.mq.user={userName}
connName you can find in the Listener directory:
In my case IP address is equal: localhost
Port is equal: 1415
channelName you can find in Channels directory.

As per https://github.com/ibm-messaging/mq-jms-spring the default connection properties for mq-jms-spring-boot-starter are
The default attributes are
ibm.mq.queueManager=QM1
ibm.mq.channel=DEV.ADMIN.SVRCONN
ibm.mq.connName=localhost(1414)
ibm.mq.user=admin
ibm.mq.password=passw0rd
You will most likely need to set connName, user and password. The default port is 1414, but if you are running MQ in the cloud then you will need to look up in you cloud what port to use. You will get the port from the same place you look up the server url.
You may also need to supply TLS parameters - https://github.com/ibm-messaging/mq-jms-spring#tls-related-options
You can find sample code here - https://github.com/ibm-messaging/mq-dev-patterns/tree/master/Spring-JMS The 101 sample ( https://github.com/ibm-messaging/mq-dev-patterns/tree/master/Spring-JMS/src/main/java/com/ibm/mq/samples/jms/spring/level101 ) has very little code, so a good test of whether the connection parameters are right.

Change path of RabbitMQ WebSocket MQTT endpoint?

I am running a RabbitMQ instance that provides MQTT over websockets via the rabbitmq_web_mqtt plugin.
For legacy reasons, I need to support a non-default WebSocket URL.
I saw in the documentation it is possible to change the port via the { port, 1234 } config, but I could not find any way to change the WebSocket URL. It is currently set to the default path of /ws
Is it possible to change the WebSocket URL without modifying the plugin?
This has been made configurable back September 2018. See already mentioned ticket.
Add line:
# echo 'web_mqtt.ws_path = /mqtt' >> /etc/rabbitmq/rabbitmq.conf
# service rabbitmq-server restart
Now being accessible by (compliant) MQTT Clients. For instance at:
ws://192.168.210.84:15675/mqtt
UPDATE: RabbitMQ now allows configuration of the WebSocket URL. See this answer.
After some research, I found out that the path is not configurable

FTP polling in OSB

I've created a ftp server on localhost:21
I created on OSB (I use OEPE to play with OSB) the proxy service called FTPpol
I configured FTPpol in this way:
General configuration(first tab): messaging service
Message Type Configuration: text in message requeste type and i leave the message response type on None
Transport Configuration: protocol: ftp and Endpoint Uri: ftp://127.0.0.1/
FTP Transport Configuration: User Authentication: External User and i use a service account previously created (with the username and password need to access to ftp)
After this configuration I receive a connection error on the console everytime the proxy try the polling. The username and password are correct and the server ftp is up and reachable.
Any suggestion?
My suggestion is to use an adapter for it, as seem here:

IBM Cast Iron: MQ Put activity issues

I am trying to put a message into Websphere MQ queue from an Orchestration which is deployed on Cast Iron Live. I have used secure connector since the orchestation is deployed on Cast Iron. When I am trying to execute the flow, it fails and the message is not placed in MQ queue. The below are the errors:
Error while trying to call remote operation execute on Secure Connector for activity
com.approuter.module.mq.activity.MqPut and Secure Connector LocalSecureConnector,
error is Unable to put message on queue null. MQ returned error code 2538.
Unable to put message on queue null. MQ returned error code 2538.
Fault Name : Mq.Put.OperationActivityId : 163
Message: Unable to put message on queue null. MQ returned error code 2538.
Activity Name:Put MessageFault Time: 2015-07-15T05:40:29.711Z
Can someone please help me resolve this. Please let me know if any further details are required.
Here are the details:
Cast Iron flow is deployed on Cast Iron Cloud i.e Cast Iron Live
MQ is running on-premise
The port I am trying to connect is 1414.
Have a secure connector running on the machine where MQ is installed.
MQ version is 8.
In Cast Iron flow, I am using an MQ connector, by giving the hostname where MQ is running, port: 1414, Channel Name : SYSTEM.DEF.SVRCONN and username as mqm. Tired using my log on username, by adding it to mqm group. But this also dosent seem to work.
The return code is instructive:
2538 0x000009ea MQRC_HOST_NOT_AVAILABLE
This indicates that Cast Iron is attempting to contact MQ using a client connection and not finding a listener at the host/port that it is using.
There are a couple of possibilities here but not enough info to say which it might be. I'll explain and provide some diagnostics you can try.
The 2538 indicates an attempt to contact the QMgr has failed. This might be that, for example, the QMgr isn't listening on the configured port (1414) or that the MQ listener is not running.
The error code says the queue name is "null". The question doesn't specify which queue name the connector is configured with but presumably it's been configured with some queue name. This error code suggests the Secure Connector on the MQ server side doesn't have its configuration installed.
The Cast Iron docs advise connecting with an ID in the mqm group but do not mention that on any MQ version 7.1 or higher this is guaranteed to fail unless special provisions are made to allow the admin connection. It may be that it's actually failing for an authorization error and the connector not reporting the correct error.
If it is as simple as the listener not running, that's easy enough to fix. Just start it and make sure it's on 1414 as expected.
Next, ensure that the Secure Connector has the configuration that was created using the Cast Iron admin panel. You need to understand why the error code says the queue name is null.
Now enable Authorization Events and Channel Events in the QMgr and try to connect again. The connector on the MQ server should connect when started and if successful you can see this by looking at the MQ channel status. However, if unsuccessful, you can tell by looking at the event messages or the MQ error logs. Both of these will show authorization failures and connection attempts, if the connection has made it that far.
The reason I'm expecting 2035 Authorization Error failures is that any QMgr from v7.1 and up will by default allow an administrative connection on any channel. This is configured in the default set of CHLAUTH rules. The intent is that the MQ admin would have to explicitly provision admin access by adding one or more new CHLAUTH rules.
For reasons of security SYSTEM.DEF.* and SYSTEM.AUTO.* channels should never be used for legitimate connections. The Best Practice is to define a new SVRCONN, for example one named CAST.IRON.SVRCONN and then define a CHLAUTH rule to allow the administrative connection.
For example:
DEFINE CHL(CAST.IRON.SVRCONN) CHLTYPE(SVRCONN) TRPTYPE(TCP) REPLACE
SET CHLAUTH('CAST.IRON.SVRCONN') TYPE(ADDRESSMAP) +
ADDRESS('127.0.0.1') +
USERSRC(MAP) MCAUSER('mqm') +
ACTION(REPLACE)
SET CHLAUTH('CAST.IRON.SVRCONN') TYPE(BLOCKUSER) +
USERLIST('*NOBODY') +
WARN(NO) ACTION(REPLACE)
The first statement defines the new channel.
The next one allows the connections from 127.0.0.1 which is where the Secure Connector lives. (Presumably you installed the internal Secure Connection on the same server as MQ, yes?) Ideally the connector would use TLS on the channel and instead of IP filtering the CHLAUTH rule would filter based on the certificate Distinguished Name. This rule is not nearly so slective and allows anyone on the local host to be an MQ administrator by using this channel.
The last statement overrides the default CHLAUTH rule which blocks *MQADMIN with a new rule that blocks *NOBODY but just for that channel.

ActiveMQ network of brokers: random conectivity with rebalanceClusterClients and updateClusterClients

I have a network of brokers with the following configuration
<transportConnectors>
<transportConnector name="tomer-amq-test2" uri="tcp://0.0.0.0:61616" updateClusterClients="true" rebalanceClusterClients="true" updateClusterClientsOnRemove="true"/>
</transportConnectors>
I expect that when I connect using the URL
failover:\(tcp://tomer-amq-test2:61616\)?backup=true
the broker shall update th client with the full list of brokers it is conencted too, and the client shall connect to one randomly, and to a second as backup
however this is not happening and the client connects only to the specified broker in the url
help anyone?
Tx Tomer
figured out the problem (at least on my env)
when a broker updates another broker that it is up, it identifies itself by the server name.
once the server name of all brokers was added to /etc/hosts on the client side, all was well
:)
I guess this is bad practice, and the broker should identify itself by ip and not by hostname
I was running activeMQ 5.5.1 on ubuntu 10.4
Your client will only be updated with the full broker-list if some or the following properties are true: updateClusterClients rebalanceClusterClients and updateClusterClientsOnRemove.
you have to set them manually on your client as they are false by default.

Glassfish 3.1 - How to configure JMS on multiple domains?

Due to classloading issues I need to deploy an ear and a war in separate domains in the same instance of Glassfish 3.1.1. The war sends messages to a queue and and MDB in the ear should receive and action it.
The JMS is set up in the domains thusly:
domain1 default_JMS_host (server-config | Java Message Service | JMS Hosts):
Type = local
Host = localhost
Port = 7676
domain2 default_JMS_host (server-config | Java Message Service | JMS Hosts):
Type = remote
Host = localhost
Port = 7676
Originally I had the port on domain2 set to 5076, but that caused connection refused exceptions on domain startup.
With this setup everything seems to load fine (no errors in domain2 server.log) but it doesn't pick up the messages put in the queue by the war file. I have confirmed that the messages are being put in the queue by the war using the command:
/<glassfish>/mq/bin/imqcmd list dst -b localhost:7676 -u admin
I have tried searching for how to set up JMS with multiple domains in the same Glassfish instance, but haven't found anything useful. Can someone point me to a good resource on how to set this up?
portbase info also could be usefull for this questuion:
https://blogs.oracle.com/alexismp/entry/flexible_glassfish_domain_creation_using
so, for several domains you cah set up the portbase with one JMS port per domain
