cxf deployment :No services have been found.

No services have been found.

This problem occurs when you want to deploy a web service using cxf on server like tomcat:

and you have a deployment descriptor like this:

<servlet>
 <servlet-name>cxfservlet</servlet-name>
 <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
 <load-on-startup>1</load-on-startup>
 </servlet>

  <servlet-mapping>
 <servlet-name>cxfservlet</servlet-name>
 <url-pattern>/services/*</url-pattern>
 </servlet-mapping>


And a configuration file for cxf .This file must have the name cxf-servlet.xml and this is a rule .

So to resolve this problem of  "No services have been found", you must verify the name of that file,first of all.

This error occurs,if you user JWT for authentification when you develop Using SpringBoot.

if you are using in your pom.xml for example like this:

<parent>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-parent</artifactId>

<version>2.0.4.RELEASE</version>

<relativePath/> <!-- lookup parent from repository -->

</parent>

and these dependencies:

<dependency>

    <groupId>org.springframework.security.oauth</groupId>

    <artifactId>spring-security-oauth2</artifactId>

    <version>2.0.7.RELEASE</version>

</dependency>

<dependency>

    <groupId>org.springframework.security</groupId>

    <artifactId>spring-security-jwt</artifactId>

    <version>1.0.4.RELEASE</version>

</dependency>

change the parent version to 1.5.4.RELEASE, and it will be like this:

<parent>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-parent</artifactId>

<version>1.5.4.RELEASE</version>

<relativePath/> <!-- lookup parent from repository -->

</parent>

and others put their versions like this:

<dependency>

    <groupId>org.springframework.security.oauth</groupId>

    <artifactId>spring-security-oauth2</artifactId>

   </dependency>

<dependency>

    <groupId>org.springframework.security</groupId>

    <artifactId>spring-security-jwt</artifactId>

  

</dependency>

to resolve it you must follow these steps:

List Java contains doesn't work as expected

List Java contains doesn't work as expected

I have this code not working as expexted:

import java.util.Arrays;
import java.util.List;

public class Test {
static int[] listm = { 2,3,5 };

public static void main(String[] args) {

contains(listm, 2);
}

public static boolean contains(int[] array, int key) {

List l = Arrays.asList(array);
boolean contain = l.contains(key);
System.out.println("" + contain);
return contain;
}

}

it returns  false,even the item 2 is found on the collection listm .

To resolve this problem,we must change the generic value of the collection to Integer.

The code become like this.


public class Test {
static Integer[] listm = { 2,3,5 };

public static void main(String[] args) {

contains(listm, 2);
}

public static boolean contains(Integer[] array, int key) {

List<Integer> l = Arrays.asList(array);
boolean contain = l.contains(key);
System.out.println("" + contain);
return contain;
}

}








it works :)

Caused by: java.lang.RuntimeException: Could not find conduit initiator for address:

Caused by: java.lang.RuntimeException: Could not find conduit initiator for address: 

This problme can be caused by the absence of  this jar :cxf-rt-transports-http-3.0.0.jar.

org.apache.cxf.Messages != org.apache.cxf.APIMessages

java.lang.IllegalArgumentException: org.apache.cxf.Messages != org.apache.cxf.APIMessages

This exeption can occur when we use web service with cxf.
Here,we have a problem of jar between server side and client side.
for example on server we have this version cxf-core-3.0.0.jar  wich  contains org.apache.cxf.Messages

But on client we find this version cxf-bundle-20.10 wich  contains org.apache.cxf.APIMessages.

To resolve this exception we have just to change cxf-bundle-20.10 by  cxf-bundle-3.0.0-milestone2.zip  wich  contains org.apache.cxf.Messages.

I hope this help you :)

Deprecated: mysql_connect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in


to resolve this deprecated warning you can add   "@" operator before function name like

 @mysql_connect("localhost","root","");

or add this function

 error_reporting(E_ALL ^ E_DEPRECATED)

in fact:
To not display the E_DEPRECATED errors (for example) without changing the rest of the configuration :
error_reporting(error_reporting() & (-1 ^ E_DEPRECATED));

Exception in thread "main" org.hibernate.PropertyValueException: not-null property references a null or transient value: persistance.Client.prenom

at org.hibernate.engine.Nullability.checkNullability(Nullability.java:72)

This exception occurs because you have a column named prenom wich is not nullable , and you forgot to set it's value.

So to resolve this issue you must add a valuet to this property .

org.hibernate.LazyInitializationException: could not initialize proxy - no Session

org.hibernate.LazyInitializationException: could not initialize proxy - no Session
 org.hibernate.proxy.AbstractLazyInitializer.initialize(AbstractLazyInitializer.java:57)
 org.hibernate.proxy.AbstractLazyInitializer.getImplementation(AbstractLazyInitializer.java:111)
 org.hibernate.proxy.pojo.cglib.CGLIBLazyInitializer.invoke(CGLIBLazyInitializer.java:150)

This problem occurs when you have a relation between tow tables.
Your objects are lazy initialized. That's mean, they are initializing only on demand on non-closed session. 
To resolve this exception add laze=false  into you mapping file or  change FetchType.LAZY to FetchType.EAGER
if you use annotation.

In fact,the EAGER strategy is a requirement on the persistence provider runtime that data must be eagerly fetched. The LAZY strategy is a hint to the persistence provider runtime that data should be fetched lazily when it is first accessed.

To resolve this issue you must go to your build.gradle on your module
and add:

 multiDexEnabled true

after defaultConfig {

and  add:
