The changes which I made in server side:
#Bean(name = {"hazelcast"})
public HazelcastInstance hazelcastInstance() {
ClientConfig clientConfig = new ClientConfig();
clientConfig.getGroupConfig().setName(integrationSettings.getHazelcastClusterGroupName())
.setPassword(integrationSettings.getHazelcastClusterGroupPass());
final ClientNetworkConfig clientNetworkConfig = new ClientNetworkConfig();
clientNetworkConfig.addAddress("127.0.0.1:6701");
clientConfig.setNetworkConfig(clientNetworkConfig);
clientConfig.setInstanceName("INTEGRATION_INSTANCE");
final String hazelcastEnterpriseLicenseKey = null;
if (hazelcastEnterpriseLicenseKey != null) {
clientConfig.setLicenseKey(hazelcastEnterpriseLicenseKey);
}
return HazelcastClient.newHazelcastClient(clientConfig);
}
I will be getting my groupname and password from my property file.
My client side code:
ClientConfig clientConfig = new ClientConfig();
clientConfig.getGroupConfig().setName(hazelcastGroupName).setPassword(hazelcastGroupPwd);
clientConfig.getNetworkConfig().addAddress(serverAddress);
hazelcastInstance = HazelcastClient.newHazelcastClient(clientConfig);
My error log:

I need to connect my hazelcast as a client, but this bean exception is failing the deployments. Is there is any other way of doing it?
Looking at your code you are creating "Hazelcast-Client" on the server side and Client Side. In the server side code , please create a hazelcast ServerMember instance by passing "Config" object and not "ClientConfig" more like
#Bean
public HazelcastInstance hazelcastInstance() throws Exception {
Config cfg = new Config();
...
...
HazelcastInstance instance = Hazelcast.newHazelcastInstance(cfg);
return instance;
}
The the Hazelcast-client can connect to the Hazelcast ServerMember. You also need to ensure the ServerMember is started before client can connect to it.
Please help as I don't know what is wrong here. I have a very simple REST GET service but I keep running into the error below:
#GET
#Path("users/{id}")
#Produces("text/plain")
public Response getUserById(#PathParam("id") String id) {
return Response.status(200).entity("getUserById is called, id : " + id).build();
}
And the exception I'm seeing is below:
[ERROR ] SRVE0315E: An exception occurred: java.lang.Throwable: javax.servlet.ServletException: SRVE0207E: Uncaught initialization exception created by servlet

I want to load data into titan ,which's backend is hbase.So I changed the example from https://github.com/thinkaurelius/titan/blob/titan10/titan-core/src/main/java/com/thinkaurelius/titan/example/GraphOfTheGodsFactory.java
a little.But it ocurred many Exceptions when i connect.

Here is the code:
TitanGraph g = TitanFactory.build().set("storage.backend","hbase").set("storage.hostname","192.168.200.121,192.168.200.115")
.set("storage.hbase.table","mytitan").set("storage.hbase.ext.zookeeper.znode.parent","/hbase-unsecure").set("storage.port",2181).open();
BTW,I can connect to the Hbase cluster,it looks fine.

I'm developing a framework that, as one of its features, enables robots to use a rule based system. We began with Jess as the RBS, and now wanted to implement drools (using Drools 5.2.0 final), which works on our development machines running on OpenJDK 6.
Our robot controller runs ARM Linux and JamVM, previously 1.4.3, but I recently compiled 1.5.4 because it was missing classes needed by drools. After failures, I installed JamVM in a virtual machine using the same configurations as when I compiled it for the controller, and there it failed with the same exceptions.
A little research showed that there are bug reports for Drools + JamVM, but this also means that it generally does work.
When Running the framework with precompiled rules with the following code...
kBase = KnowledgeBaseFactory.newKnowledgeBase();
ObjectInputStream in;
Collection<KnowledgePackage> kpkgs;
try {
in = new ObjectInputStream(Thread.currentThread().getContextClassLoader().getResourceAsStream(
packageFile));
kpkgs = (Collection<KnowledgePackage>) in.readObject();
in.close();
} catch(IOException e) {
throw new DisboticsException("Couldn't read drools knowledge package file!", e);
} catch(ClassNotFoundException e) {
throw new DisboticsException("Drools knowledge package file didn't contain expected instance.", e);
}
kBase.addKnowledgePackages(kpkgs);
kSession = kBase.newStatefulKnowledgeSession();
...I got this exception:

...which works in OpenJDK. weirdly, it turns out that the list in question in JavaDialectRuntimeData is obtained via Collections.emptyList() and is never changed again (or so eclipse suggests...).

again, compiling the rules worked just fine in OpenJDK. We're using Janino, and it is properly referenced on the classpath (the classpath used at runtime is created by the Maven build, so contains all jars referenced by drools/janino/ anything else)
Does anyone know what's going on here and/or how to get Drools working with JamVM?
Are you compiling the knowledge packages using OpenJDK 1.6? and then trying to load it with 1.5.4? You should try compiling the original packages using 1.5.4 and see if you have the same errors.
For the stack trace, it looks like you are trying to add something to an unmodifiable list right?
Basically you are getting the exception here: kBase.addKnowledgePackages(kpkgs);
Right?
