Questions on IBM WebSphere 8.5.5 to WildFly 9.0.2
yogendra.joshi Dec 28, 2015 4:20 PMHello Team,
FIrstly, I would like to congratulate Jaikiran and team for continuous development on the WildFly platform. I've been fan of this platform ever since it came out! I am currently working on converting our tightly integrated IBM application to WildFly 9.0.2. Some of the things that we use in our application are as follows. Each bullet has a question that require inputs from WildFly team:
- Network Deployment - We use a clustered environment which has multiple servers, nodes, nodegroups, deployment manager, etc. I know Wildfly has a domain mode which replicates IBM ND environment.
- Question 1: Does WildFly has detailed documentation on above concepts
- Question 2: Does WildFly provide deployment scripting support. WebSphere has wsadmin commands which could be invoked through ant which then integrates neat with Bamboo or any other CI server.
- EJB 3.1 support - Most of the business layer comprises of EJBs and Business Objects. EJBs are implemented using EJB 3.1 specification. I understand WildFly is implemented on Java EE 7 and supports EJB 3.1 and 3.2.
- Question: When I tried to deploy the same EAR from WebSphere 8.5.5. into WildFly 9.0.2, I got an error saying "beanInterface is required for <ModuleName>". I know this is NOT mandatory as per the spec or else IBM WAS also would have complained about this. How do I get this to work in WF? There are more than 2000 EJB's spread across 40 EJB modules, we are using @LocalBean as all of our SLSB are local to the WAS instance. It is not practical to go and add "beanInterface=NoInterfaceView.class" to each of the EJB annotations. Java EE 6 and Java EE 7, both the spec and online documentation mentions beanInterface as "Optional Elements".
- The application currently uses shared libraries to access external libraries and in WAS its dead simple, create a shared library and reference the shared library in the class loader. How is this done in WF?
- We currently use IBM WODM for business rules. I am assuming JBoss BRMS would be an ideal solution for converting the business rules. Is there a possibility to re-use the existing rules from IBM? Or is there a tool which would help us with the estimates of converting it to JBOSS BRMS? Something like JBoss WindUp, but for Rules?
- How can I reference a specific JAR as JVM argument? In Websphere, I goto Generic JVM Arguments and add the path to the properties jar that I need at startup.
- Lastly, I tried using JBoss Windup an our EAR which is 145MB and it just crashes everytime with OutOfMemoryError. Is there a way I could have WindUp run for days without being timed out or OutOfMemory?
I am very excited to learn about this new platform and how to get this as part of our new application server support!
Thanks,
Yogendra
