I need to know which framework or API to use for my following requirement. I am currently using native java code for all this.
Requirement
I have an application where there could be multiple JMS/Rest/TCP connections. These connections can grow at runtime. User wil have a screen to define new incoming or outgoing connections. I am using Native and works fine but I want to make use of an efficient framework or API like Spring, Camel etc ?
Need Guidance.
I have been able to get this all working. There are multiple solutions to get do dynamic JMS
1. I used Spring JMS API and created the dynamic JMS connections by loading the dynamic child context into application. For this I followed the spring's dynamic FTP sample and inserted JMS beans in the example instead of FTP ones.

i'm not quite sure if spring integration is the right toolset for me.
I would like to enter connection data (SFTP/FTP) into a database and use it time scheduled to fetch data.
But I have several problems now,
can I dynamically add SFTP /FTP jobs at spring integration?
can I cluster spring integration jobs?
I have found several solutions to have multiple SFTP polls, but they don't work.
For example: spring integration : solutions/tips on connect multiple sftp server?
Thanks for your feedback.
You can do that using Spring Integration Java DSL dynamic flows: https://docs.spring.io/spring-integration/docs/current/reference/html/dsl.html#java-dsl-runtime-flows
So:
you do a JDBC Inbound Channel Adapter to poll settings from the database: https://docs.spring.io/spring-integration/docs/current/reference/html/jdbc.html#jdbc-inbound-channel-adapter
You create dynamic flows using a IntegrationFlowContext populate SFTP server connection factory and remote directory into a SFTP Inbound Channel Adapter and start that dynamic flow: https://docs.spring.io/spring-integration/docs/current/reference/html/sftp.html#sftp-inbound
Another option is to consider to use a RotatingServerAdvice: https://docs.spring.io/spring-integration/docs/current/reference/html/sftp.html#sftp-rotating-server-advice
To make such a solution robust in the cluster you should use SftpPersistentAcceptOnceFileListFilter configured with shared MetadataStore: https://docs.spring.io/spring-integration/docs/current/reference/html/system-management.html#metadata-store.
This sample demonstrate a technique how to use dynamic flows for TCP/IP, but principle is the same: https://github.com/spring-projects/spring-integration-samples/tree/master/advanced/dynamic-tcp-client.
Also see this SO thread: how can i connect with different SFTP server dynamically?
In our project we have a requirement to connect to IBM IMS and get data. Many of the existing applications are done it through code more coupled with IMS.
In one of the application we are using Spring CCI support and providing the CCIConnectionFactory to the JDBCTemplate and using it in a relational (kind of) manner.
However we are building a new application which is not using Spring framework. We are making use of JAVA CDI and it's aspects. But to integrate it with IMS through CCI I can see Spring is the best option. Anyone have experienced on this CCI connections? What way is the best you think? And any other frameworks in Java you are familiar with - apart from Spring's support?
Appreciate your help and input.
I had the same question 5 Month ago and it was very hard to collect information about jca. If your project works with wildfly or jboss take a look on my inbound-ra-example project. At first you must know what kind of resource adapter (RA) you need, inbound or outbound. In short, an inbound RA acts as a server for external data and send the data to a message driven bean. An outbound RA is called from an EJB via a connection factory and initiate the connection to the external information system. Read the readme.md of my example project. The inbound RA is much more difficult as an outbound RA. Generate the skeleton of your ra with the ironjacamar codegenerator. I described the process in my example project.
So I have a ConnectionFactory configured from a properties file containing a broker list, meaning that when the session gets created it will have connected to one of the brokers in the list based on availability/policy and so on.
My question is: how to programmatically figure out from the Java code, at runtime, which of the broker URLs have I actually connected to.
What I am trying to achieve is to send management GET requests to the broker API programmatically, but for that I need to obtain its URL. Am I thinking about this the wrong way?
P.S. I am doing this from a Spring-boot application, but am not too fussed about using the JmsTemplate.
I am working on existing project which uses JMS and spring. I am new to JMS. I need to test that application. My aim is to test that my classes which are used in the application are executed or not.
So can anybody provide me a way in which I can test the application which uses JMS?
I have searched on Google but everyone get started with a sample application. But I want to test my existing application, meaning how my application gets connected with another module. Is there any tool like SOAPUI for JMS test of my existing application, meaning something from which I can execute my classes or listener.
Edit 1
There is a scenario in my project that my module listen a JMS Queue and send SMS or Email to user but actually I am not getting that how my module connected to other module can anybody give me a way so I can find in that direction means which services or APIs used in there.
I've managed to get Spring Xd working for a scenario where I have data coming in from one JMS broker.
I potentially am facing a scenario where data ingestion could happen from different sources thereby needing me to connect to different brokers.
Based on my current understanding, I'm not quite sure how to do this as there exists a JMS config file which allows you to setup only one broker.
Is there a workaround to this?
At the moment, you would have to create a separate jms-[provider]-infrastructure-context.xml for each broker (in modules/common), say call the provider activemq2.
Then use --provider=activemq2 in the module definition.
(I recently used this technique to test sonicmq and hornetq providers).
