SpringJMS 3.0.4 not connecting MQ 7.5 Connection using UserName - authentication

SpringJMS 3.0.4 not connecting MQ 7.5 Connection using UserName
Not able to connect MQ 7.5 Queue manager from Spring JMS version 3.0.4 with username. Username is passed to provide appropriate authorization to queue. We are using SpringJMS which uses MQ Client libraries available on the same machine. MQ Manager/Server is on remote machine

I can confirm that the MQQueueuConnectionFactory.createConnection method been called by Spring is the version that passes no username/password. This is why you are seeing the MQRC_NOT_AUTHORIZED as the username is not being passed to the queue manager.
I am not a spring expert but I believe that the new myConnectionFactory2 bean that you have added needs to reference your CachingConnectionFactory bean (queueConnectionFactory) rather than directly referencing the MQQueueConnectionFactory bean (mqConnectionFactory). So change this:
<bean id="myConnectionFactory2" class="org.springframework.jms.connection.UserCredentialsConnectionFactoryAdapter">
<property name="targetConnectionFactory"> <ref bean ="mqConnectionFactory"/> </property>
<property name="username"> <value>"tbossmqd"</value> </property>
<property name="password"> <value>"password1"</value> </property>
</bean>
to be this:
<bean id="myConnectionFactory2" class="org.springframework.jms.connection.UserCredentialsConnectionFactoryAdapter">
<property name="targetConnectionFactory"> <ref bean ="queueConnectionFactory"/> </property>
<property name="username"> <value>"tbossmqd"</value> </property>
<property name="password"> <value>"password1"</value> </property>

Failed to allocate a JMS connection Payara and Websphere MQ

[WebSphere MQ installation subdirectory]
1I installed an IBM resource adapter to a Payara (Glassfish) server using the instructions on the below page from the IBM website:
https://www.ibm.com/support/knowledgecenter/en/SSFKSJ_8.0.0/com.ibm.mq.dev.doc/q121520_.htm
However when I try to test the Connector Connection Pool using the ping option I get the following error:
'Ping Connection Pool failed for jms/ivt/IVTCF-Connection-Pool. MQJCA1011: Failed to allocate a JMS connection., error code: MQJCA1011 Please check the server.log for more details.'
I am running Payara Server 4.1.2.181 and trying to connect to IBM WebSphere MQ Explorer Version: 8.0.0.5. Below are the relevant connection details from the domain.xml file I am using:
<connector-connection-pool resource-adapter-name="wmq.jmsra" max-pool-size="250" ping="true" steady-pool-size="1" name="jms/ivt/IVTCF-Connection-Pool" connection-definition-name="javax.jms.ConnectionFactory">

Do you have a local queue called 'QM'? You are using 'localhost', so is it running on your local PC? And did you configure the MQ listener to use port # 1418?
Finally, do not use the "SYSTEM.DEF.SVRCONN". Create a channel for your own use. i.e. 'TEST.CHL'. Also, you could be blocked from using the SYSTEM.* channel by a CHLAUTH rule.
As #Roger had highlighted, the issue in my case was that the channel was blocked by the CHLAUTH rule. I fixed the issue by disabling authorisation on the channel using the below commands on the IBM Integration Console:
alter QMGR CHLAUTH(DISABLED)
alter AUTHINFO(SYSTEM.DEFAULT.AUTHINFO.IDPWOS) AUTHTYPE(IDPWOS) CHCKCLNT(none)
REFRESH SECURITY TYPE(CONNAUTH)

The simplest way is to use the control.sh script, which you’ll find in the bin directory:

Could not refresh JMS Connection for destination 'queue://inventorydsDestination' - retrying in 5000 ms. Cause: AOP configuration seems to be invalid

I'm getting the following exception when I re-deploy the application war in the Tomcat manager. For example, on first time deployment it connects to the external ActiveMQ properly but when I stop/start the war in Tomcat manager, then the following execption is thrown repeatedly. After this, the JMS does not connect to ActiveMQ with the below exception:

I had similar issue and discovered it was a classpath issue between tomcat and my web application. I needed to set the scope of the jms dependency in my web app to provided instead of the default (i.e. compile). That way, my WAR deployable did not contain another jms jar that clashed with the jms classes contained in the apache-activemq-all jar that was located in the tomcat lib folder.

How to use simple-spring-memcached with AWS Auto Discovery

How to use simple-spring-memcached library (SSM) with AWS Elasti Cache Auto Discovery feature? We are using spymemcached as client.
So currently you are using spymemcached and want to add cache layer using simple spring memcached (SSM), right? If yes then please provide your current configuration for spymemcached. It should be easy to use the same configuration with SSM.
UPDATE
I've added new dedicated memcached provider in SSM that uses AWS ElastiCache Cluster Client. It is available on master branch and not released yet. If you build SSM from master or use snapshot available in this repository then you can use Auto Discovery feature.
Remove dependencies to spymemcached-provider and spymemcached instead add a new dependency:
<dependency>
<groupId>com.google.code.simple-spring-memcached</groupId>
<artifactId>aws-elasticache-provider</artifactId>
<version>3.4.1-SNAPSHOT</version>
</dependency>
Use below configuration:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

New Simple Spring Memcached version 3.5.0 with AWS Auto Discovery feature is available on github and central maven repository.

Apache Camel with IBM MQ

Hello has anyone ever used Camel with IBM's MQ. We are looking at possibly using the two products together but have no example of the two products working together.
I have extensive use of IBM MQ's with camel. There is no issue using both together. I will paste a sample configuration from one of my spring context files leveraging a camel Jms Endpoint, A spring connection factory, and an IBM MQ definition.
Camel Route
from("someplace")
.to("cpaibmmq:queue:myQueueName");
Spring Context
<bean name="cpaibmmq" class="org.apache.camel.component.jms.JmsComponent" destroy-method="doStop">

<property name="channel" value="${cpa.wmq.channel}" />
<property name="hostName" value="${cpa.wmq.hostname}" />
<property name="port" value="${cpa.wmq.port}" />
<property name="queueManager" value="${cpa.wmq.mqmanager}" />
</bean>
</constructor-arg>
</bean>
The best I have been able to get is documented below, illustrated as a Spring XML application context that itself hosts the CAMEL context and routes. This sample works with the IBM native MQ JCA-compliant resource adapter v7.5, CAMEL 2.16, Spring core 4.2. I have deployed it in Glassfish, Weblogic, and JBoss EAP7 servers.
The complexity is bound to handling the flow of MQ reports whose philosophy conflicts with that of a plain JMS reply-to message. For a detailed explanation, please refer to Implementing native websphere MQ with CoD over Camel JMS component
This example based on the CAMEL XML DSL is self-contained and easy to test.
We start with Spring & CAMEL declarations:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:util="http://www.springframework.org/schema/util"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:camel="http://camel.apache.org/schema/spring"
xmlns:jee="http://www.springframework.org/schema/jee"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd
http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd
http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsd">
The CAMEL context follows with 2 routes: MQ to JMS and JMS to MQ, here chained to form a bridge to ease testing.
<camel:camelContext id="mqBridgeCtxt">
<camel:route id="mq2jms" autoStartup="true">
Weird: on Weblogic, the only way to get (e.g.) 3 listeners is to enforce 3 connections (with 3 Camel:from statements in sequence) with max 1 session each, otherwise an MQ error ensues: MQJCA1018: Only one session per connection is allowed. On JBoss, you can simply adjust concurrentConsumers=...
<camel:from uri="wmq:queue:TEST.Q1?concurrentConsumers=1&disableReplyTo=true&
acknowledgementModeName=SESSION_TRANSACTED"/>
The disable disableReplyTo option above ensures that CAMEL will not produce a reply before we can test the MQ message type to be 1=Request(-reply) or 8=datagram (one way!). That test and reply construction is not illustrated here.
Then we enforce the EIP to InOnly on the next posting to plain JMS to be consistent with the Inbound MQ mode.
<camel:setExchangePattern pattern="InOnly"/>
<!-- camel:process ref="reference to your MQ message processing bean fits here" / -->
<camel:to uri="ref:innerQueue" />
</camel:route>
This ends the MQ-to-jms route; next comes the jms-to-MQ route still in the same CAMEL context:
<camel:route id="jms2mq" autoStartup="true">
<camel:from uri="ref:innerQueue" />
<!-- remove inner message headers and properties to test without inbound side effects! -->
<camel:removeHeaders pattern="*"/>
<camel:removeProperties pattern="*" />
<!-- camel:process ref="reference to your MQ message preparation bean fits here" / -->
Now comes the request flag for the MQ CoD report to be returned by remote destination. We also enforce the MQ message to be of Datagram type (value 8).
<camel:setHeader headerName="JMS_IBM_Report_COD"><camel:simple resultType="java.lang.Integer">2048</camel:simple></camel:setHeader>
<camel:setHeader headerName="JMS_IBM_Report_Pass_Correl_ID"><camel:simple resultType="java.lang.Integer">64</camel:simple></camel:setHeader>
<camel:setHeader headerName="JMS_IBM_MsgType"><camel:simple resultType="java.lang.Integer">8</camel:simple></camel:setHeader>
The ReplyTo queue can be specified either via the ReplyTo uri option, else as a header as below.
Next we do use CamelJmsDestinationName header to enforce suppressing of the JMS MQ message header MQRFH2 (using targetClient MQ URL option value 1). In other words, we want to send a plain vanilla MQ binary message (i.e. Only the MQMD message descriptor followed by the payload).
<camel:setHeader headerName="JMSReplyTo"><camel:constant>TEST.REPLYTOQ</camel:constant></camel:setHeader>
<camel:setHeader headerName="CamelJmsDestinationName"> <camel:constant>queue://MYQMGR/TEST.Q2?targetClient=1</camel:constant></camel:setHeader>
More MQMD fields may be controlled through reserved JMS properties as illustrated below. See restrictions in IBM doc.
<camel:setHeader headerName="JMS_IBM_Format"><camel:constant>MQSTR </camel:constant></camel:setHeader>
<camel:setHeader headerName="JMSCorrelationID"><camel:constant>_PLACEHOLDER_24_CHARS_ID_</camel:constant></camel:setHeader>
The destination queue in the URI is overwritten by the CamelJmsDestinationName above, hence the queue name in the URI becomes a placeholder.
The URI option preserveMessageQos is the one that - as observed - allows sending a message with the ReplyTo data being set (to get the MQ CoD Report), yet prevent CAMEL to instantiate a Reply message listener by enforcing the InOnly MEP.
<camel:to uri="wmq:queue:PLACEHOLDER.Q.NAME?concurrentConsumers=1&
exchangePattern=InOnly&preserveMessageQos=true&
includeSentJMSMessageID=true" />
</camel:route>
</camel:camelContext>
We have not finished, we have still to declare our queue factories for both a native JMS provider and Websphere MQ (via the native IBM WMQ JCA Resource Adapter), to be adjusted to your context.
We use here JNDI lookups on administrative objects.
<camel:endpoint id="innerQueue" uri="jmsloc:queue:transitQueue">
</camel:endpoint>
<jee:jndi-lookup id="mqQCFBean" jndi-name="jms/MYQMGR_QCF"/>
<jee:jndi-lookup id="jmsraQCFBean" jndi-name="jms/jmsra_QCF"/>
<bean id="jmsloc" class="org.apache.camel.component.jms.JmsComponent">
<property name="connectionFactory" ref="jmsraQCFBean" />
</bean>
<bean id="wmq" class="org.apache.camel.component.jms.JmsComponent">
<property name="connectionFactory" ref="mqQCFBean" />
</bean>
</beans>
An alternative to fetching the factories (and JCA adapters) from JNDI is to declare the JMS client as Spring beans. In Weblogic and Glassfish, you'll be better inspired by deploying the native IBM JCA resource adapter and creating JNDI resources then referenced in the Spring Context as above, in JBoss a direct MQ client bean declaration suits best as below)
<bean id="mqCFBean" class="com.ibm.mq.jms.MQXAConnectionFactory">
<property name="hostName" value="${mqHost}"/>
<property name="port" value="${mqPort}"/>
<property name="queueManager" value="${mqQueueManager}"/>
<property name="channel" value="${mqChannel}"/>
<property name="transportType" value="1"/> <!-- This parameter is fixed and compulsory to work with pure MQI java libraries -->
