Hi Devs Since several days I'm trying to build a proper application, using the andes-client.jar. Because I'm not so deep familiar with all this packaging mechanisms, classloader in WebContainer/ApplicationServer and library conflicts, I want to ask you Devs directly and hope to get some hints from some of you.
What I need to do: For a customer I need to implement a WSO2 client into our software for connecting to a WSO2 MessageBroker. What I've done: I've downloaded the WSO2 Message Broker 3.1.0 and installed it on a virtual machine. According to the 'Samples' documentation of the MB, I copied the andes-client-3.1.1.jar into our application. Everything works fine so far. I can connect to the Message Broker and can read the sent messages. My environment: At the moment I'm using a WildFly 10 application server (we will switch back to a simple servlet container like Tomcat in near future. For that reason we have prepared our deployment to have only a .war file. No .ear files anymore). But for now, I've created a server module for activating the andes-client. Activating and using of this 'WSO2' module works perfectly together with my MB virtual machine. My problem: Connecting to a WSO2 MB is just a small part of our software. Another small part of our application is connecting to a directory server (LDAP, a.s.o.) For doing that, I use the Apache's directory api. And here my problem begins... Apache's directory api uses the Apache mina artifact (version 2.0.9). The artifact is referenced through a maven dependency. Your andes-client-3.1.1.jar bundle includes the Apache's mina package in version 1.1.7. The package structure and class naming of the different mina versions seems to be completely incompatible, so each artifact (andes-client and directory) needs the coresponding mina version. Otherwise those artifacts does not work proper. What do you recommend me to solve this problem? Could you give me some hints / key points, how to avoid this library conflicts? I'm not sure if OSGi would be the right way (I don't have any knowledge about OSGi and to be honest, the documentation is so extremely large that I really don't know where to begin to read). Also I thought about relocating the org.apache.mina to org.wso2.apache.mina inside the andes-client.jar. Would this be a reasonable way? Or is it planned in near future that the mina artifact would be replaced with a newer version? Thank you very much for some hints. I would be glad to hear from you! If you need more clarifying information from me, feel free to ask Greets, Michael
