I am trying to generate web services in Eclipse by using the Apache CXF framework.
First I am creating the Java class corresponding to the desired web service and then I generate two dynamic web projects, one for the web service (wsdl file) and another one for the clients. The web web services work well after I create them but after some time (one-three days) I get the error displayed in the image at the server startup.

What can cause this error which only appears after the web services are used repeatedly?
http://i.stack.imgur.com/4mTNZ.jpg
http://i.stack.imgur.com/rYkQb.jpg
Hi, the client is automatically generated in the following way:
private static final QName SERVICE_NAME = new QName("http://read_variable/", "ReadVariableNodeServiceService");
URL wsdlURL = ReadVariableNodeServiceService.WSDL_LOCATION;
ReadVariableNodeServiceService ss = new ReadVariableNodeServiceService(wsdlURL, SERVICE_NAME);
SEIReadValue port = ss.getReadVariableNodeServicePort();
{
System.out.println("Invoking getValue...");
java.lang.String _getValue_arg0 = "Alina";
java.lang.String _getValue_arg1 = "WorkspaceS1";
try {
double _getValue__return = port.getValue(_getValue_arg0, _getValue_arg1);
System.out.println("getValue.result=" + _getValue__return);
................
Last week I have found an interesting documentation which recommends the following way to call a web service:
ClassPathXmlApplicationContext context=new ClassPathXmlApplicationContext(new String[]{"read_variable/client3_beans.xml"});
SEIReadValue port = (SEIReadValue) context.getBean("readvariableClient");
{
System.out.println("Invoking getValue...");
java.lang.String _getValue_arg0 = "Alina";
java.lang.String _getValue_arg1 = "WorkspaceS1";
try {
double _getValue__return = port.getValue(_getValue_arg0, _getValue_arg1);
System.out.println("getValue.result=" + _getValue__return);
.........
What do you think? May this be the reason for my error?
I am very happy that I have almost found out the cause of my error. But I am a beginner in web services and I haven't understood your message entirely.
I want to specify that I have a set of basic/simple web services, and then based on these web services I have created a complex web service where I obtain the context
of each simple web service in order to obtain its functionality, and as you said (as I understood) this is not the right approach.
ClassPathXmlApplicationContext context=new ClassPathXmlApplicationContext(new String[]{"write_a_matrix/client2_beans.xml"});
SEIWriteMatrix port = (SEIWriteMatrix) context.getBean("write_a_matrix_Client");
...........................................................
ClassPathXmlApplicationContext context_WV=new ClassPathXmlApplicationContext(new String[]{"write_value/client1_beans.xml"});
SEIWriteValue port_WV = (SEIWriteValue) context_WV.getBean("write_a_value_Client");
...........................................................
I have created a client_beans xml file for each web service client. Is it ok? Can you provide me an example of how to call a web service and the way to hold just one App context?
I will provide you my email address < berlindutza#yahoo.com > in case you want to communicate much easier because I have seen that we are limited to a certain number of characters (for the add comment section).
Thank you a lot!
Guessing here: You are probably recreating the CXF client for every request, instead of creating it once, keeping it as a singleton and using this one instance for every subsequent request.
Ideally you should be able to generate the client using the webservice interface. If you have explicitly specified a wsdl, cxf will generate a proxy based on the WSDL, which is what seems to be happening for you. Once in a while the service which serves out the wsdl fails and you get this error.
If you are using Spring, you can do something along these lines:
<bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
<property name="serviceClass" value="...wsInterface" />
<property name="address" value="serviceURL" />
</bean>
<bean id="client" class="...wsInterface" factory-bean="clientFactory" factory-method="create" />

Trying to run 2 separate Vertx applications. They both connect to the same database. I am getting the following bind exception.
I am only using http server on one of the projects thus don't think the following even matters. But tried it anyway with no difference. The error seems to stem from the attempt to connect to DB or so I think based on the exception. How can I overcome this to be able to run both projects same time? Please advice. Thanks.
Passing in the following as an environment variable doesn't make a diff as expected:
http.port=8095
Neither does setting port in following way makes a diff.
int port = 8095;
DeploymentOptions options = new DeploymentOptions().setConfig(new JsonObject().put("http.port", port));
vertx.deployVerticle("verticle.MyVerticle", options);

I have a simple ontology and trying to do SWRL inference. On Protege 3.5 (build 663) the Jess and Drools engines work as expected while using the SWRL API an error occurs. As described in SWRLRuleEngineAPI I am using the following code:
SWRLRuleEngine ruleEngine = P3SWRLRuleEngineFactory.create(owlModel);
SWRLFactory factory = new SWRLFactory(owlModel);
SWRLImp imp = factory.createImp("Person(?x) ∧ hasGender(?x, male) → Male(?x)");
ruleEngine.infer();
classes = owlModel.getUserDefinedOWLNamedClasses();
for (Iterator it = classes.iterator(); it.hasNext();) {
OWLNamedClass cls = (OWLNamedClass) it.next();
Collection instances = cls.getInstances(false);
System.out.println("Class " + cls.getBrowserText() + " (" + instances.size() + ")");
for (Iterator jt = instances.iterator(); jt.hasNext();) {
OWLIndividual individual = (OWLIndividual) jt.next();
System.out.println(" - " + individual.getBrowserText());
}
}
All Protege API jars are referenced correctly, the code compiles well and the model is read correctly. But the following error appears on both Eclipse and NetBeans when activating the rule engine (SWRLRuleEngine ruleEngine = P3SWRLRuleEngineFactory.create(owlModel)):

It was the Protege version issue. I resolved that by downgrading to the 3.4.8 version which was suggested by Martin O'Connor Answer which has been under extensive review.
Thank you all for your efforts.
I am creating jersey rest client with jackson pojo mapping.
here is code spinet:
ClientConfig clientConfig = new DefaultClientConfig();
clientConfig.getClasses().add(JacksonJsonProvider.class);
clientConfig.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, Boolean.TRUE);
client = Client.create(clientConfig);
webResource = client.resource("url to exposed rest web service");
This code is throwing following exception at line client = Client.create(clientConfig)

I am using following jars:
jackson-core-asl:1.9.13
jackson-jaxrs:1.9.13
jackson-xc:1.9.13
jersey-client:1.1.5.1
I am fed up searching google and stackoverflow, but could not find any solution. Please suggest some solution if any one faced the same error and solved the problem.
I got the solution of the problem. It was due to jar conflicts.
I change jersey-client:1.1.5.1 to jersey-client:1.18
I know Jini (Apache River) is a pretty old and outdated technology, but I need it for an university project.
The problem is I cannot even start the lookup service script (jrmp-reggie.sh). Executing the httpd.sh works good.
Any advice? Thanks.
By the way, here is the output I'm getting:
+ java -Djava.security.policy=config/start.policy -Djava.ext.dirs=../../lib-ext/ -jar ../../lib/start.jar config/start-reggie.config

This looks like the same error I have seen when upgrading the JDK. Try JDK 1.6.0_38 (if you are using a higher version). Also the Apache River project did come across this issue and appeared to have a workaround which involves changing Levels.java
https://issues.apache.org/jira/browse/RIVER-415

Sounds like you didn't start rmid possibly.
I guess the Reggie script attempts to gain access to configuration files, but it cant!
If the script is located in: river/examples/hello/scripts
Copy it on folder higher. I mean river/examples/hello/
Then, run it. Just let me know about your output. You are using 'sh' file. But, do not use the 'bat' file. Let me know the result.
I am using Hazelcast v2.5 and Maven plugin in Eclipse . I tried running an example program in Eclipse which creates 3 map entries in the ABCD namespace . When I run my code in Eclipse it shows this WARNING message

This keeps on Iterating till the redo threshold exceeds.

Why does this occur ?
Please Help.!
You can do the following just to get started with a barebones Java class (I suggest you go through a more detailed tutorial as it might be more useful - I have not gone over accessing Hazelcast service):
Specify the map in the hazelcast.xml file as follows:
<map name="testMap">
<backup-count>1</backup-count>
<eviction-policy>NONE</eviction-policy>
<max-size policy="cluster_wide_map_size">0</max-size>
<eviction-percentage>25</eviction-percentage>
<merge-policy>hz.ADD_NEW_ENTRY</merge-policy>
<map-store enabled="true">
<class-name>models.test.StoreLoadTestMap</class-name>
<write-delay-seconds>5</write-delay-seconds>
</map-store>
<entry-listeners>
<entry-listener include value="true"local="false">models.test.ListenerTestMap</entry-listener>
</entry-listeners>
</map>
Once done, you can simply call the following from your Java app:
IMap<String, testObject> testMap = Hazelcast.getMap("testMap");
Now, you should be able to put/get values to and from the map as needed. You can use tcp or multicasting for replication based on your use case (use tcp if possible) and retrieve info from the second map for confirmation of data replication. Please also understand how data gets replicated across maps.
Hope it helps
