I have a spring boot project with Profiles namely - "scheduler","instantScheduler" .
In this project we are using WebClient for calling the external api's.
Attaching the webConfig file here :
private ClientHttpConnector connector() {
return new ReactorClientHttpConnector(HttpClient.create(ConnectionProvider.newConnection()));
}
#Bean
public WebClient webClientConfiguration() {
int memoryLimit = Integer.parseInt("10");
ExchangeStrategies exchangeStrategies =
ExchangeStrategies.builder()
.codecs(
configurer -> configurer.defaultCodecs().maxInMemorySize(1024 * 1024 * memoryLimit))
.build();
return WebClient.builder()
.clientConnector(connector())
.exchangeStrategies(exchangeStrategies)
.build();
}
While the app runs smoothly in the default profile , while I try to run it by setting any other profile as active using the vm commands ,
I run into the following error :
Caused by: java.lang.ExceptionInInitializerError: null
at reactor.netty.http.client.HttpClient.<clinit>(HttpClient.java:940) ~[reactor-netty-0.9.2.RELEASE.jar!/:0.9.2.RELEASE]
at com.octanner.initiatives.config.WebClientConfig.connector(WebClientConfig.java:22)
and
java.lang.IllegalArgumentException: port out of range:-1
at java.base/java.net.InetSocketAddress.checkPort(InetSocketAddress.java:143)
Is there any way I can modify by WebClient so that we can have profiles also co-exist in the application ?
We are running drools 6.1.0 on Weblogic 12.1.2 as a stateless EJB 3.0 Bean. The bean returns the following exception when there is more load on the server during the initialization process when it is creating new instances in the pool.

The code we have to initialize a new stateful session is as below:
protected KieSession kieSession= null;
protected ReleaseId releaseId = null; //fetched by logic to identify the release id>
if(kieSession != null){
kieSession.dispose();
kieSession = null;
}
KieServices kServices = KieServices.Factory.get();
KieContainer container = kServices.newKieContainer(this.releaseId);
kieSession = container.newKieSession();
This is happening in the constructor of the Stateless Bean.
Could you help us with any suggestions on resolving this issue?
I'm running Java/Tomcat project in Elastic Beanstalk. I've setup an Elasticache group in the same vpc. Currently, just testing with a single EC2 instance. The app is Spring Boot with spring-boot-starter-redis. It tries to ping Redis with template.getConnectionFactory().getConnection().ping(); on startup and is throwing an exception. Root cause is java.net.ConnectException: Connection refused. If I telnet to the server and port, it works. I installed redis-cli on the same instance and was able to connect and ping to the group and each node. The code also works fine on my local with local redis. Is Jedis connecting to anything other than the visible Elasticache nodes?
#Autowired
private RedisConnectionFactory connectionFactory;
/**
* Configure connection factory as per redis server.
*/
#PostConstruct
public void configureConnectionManager() {
if (cachingEnabled && connectionFactory instanceof JedisConnectionFactory) {
LOGGER.info("Connecting to Redis cache.");
JedisConnectionFactory jedisConnectionFactory =
(JedisConnectionFactory) connectionFactory;
if (port > 0) {
jedisConnectionFactory.setPort(port);
}
if (StringUtils.isNotBlank(hostname)) {
jedisConnectionFactory.setHostName(hostname);
}
jedisConnectionFactory.setUsePool(true);
RedisTemplate<Object, Object> template = new RedisTemplate<>();
template.setConnectionFactory(jedisConnectionFactory);
template.afterPropertiesSet();
LOGGER.info("Testing connection to Redis server on "
+ jedisConnectionFactory.getHostName()
+ ":" + jedisConnectionFactory.getPort());
// This will test the connection and throw a runtime exception
// if the server can't be reached.
template.getConnectionFactory().getConnection().ping();
final RedisCacheManager redisCacheManager =
new RedisCacheManager(template);
redisCacheManager.setDefaultExpiration(ttl);
this.cm = redisCacheManager;
} else {
// Default implementation incase cache turned off or exception.
LOGGER.info("Caching disabled for this session.");
this.cm = new NoOpCacheManager();
}
}
I have setup a spring boot (v 1.1.9) application to deploy as a WAR file. And I'm trying to integrate this web application with an existing data service module (added as a maven dependency).
Environment trying to deploy: WebSphere Application Server 8.5.5.4
The issue I'm facing is an application start-up failure when try to look-up a JNDI dataSource (jdbc/fileUploadDS) as below within the dependent data service module.
#Configuration
#Profile("prod")
public class JndiDataConfig implements DataConfig {
#Bean
public DataSource dataSource() throws NamingException {
Context ctx = new InitialContext();
return (DataSource) ctx.lookup("java:comp/env/jdbc/fileUploadDS");
}
}
My Spring Boot configuration:
#Configuration
#ComponentScan(basePackages = { "au.com.aiaa.fileupload.data.*", "demo" })
#EnableAutoConfiguration(exclude = { HibernateJpaAutoConfiguration.class, DataSourceAutoConfiguration.class })
public class SampleApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(applicationClass, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(applicationClass);
}
private static Class<SampleApplication> applicationClass = SampleApplication.class;
#Bean
public static Properties fileUploadJndiProperties() throws NamingException {
JndiObjectFactoryBean jndiFactoryBean = new JndiObjectFactoryBean();
jndiFactoryBean.setJndiName("props/FileUploadProperties");
jndiFactoryBean.setExpectedType(Properties.class);
jndiFactoryBean.setLookupOnStartup(true);
jndiFactoryBean.afterPropertiesSet();
return (Properties) jndiFactoryBean.getObject();
}
}
Note that I'm able to lookup props/FileUploadProperties successfully. But failing to do the same for a datasource.
My doubt is it is trying to load a EmbeddedWebApplicationContext which is not what I want.
The stack trace is:
Instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [public javax.sql.DataSource au.com.aiaa.fileupload.data.dao.configuration.JndiDataConfig.dataSource() throws javax.naming.NamingException] threw exception; nested exception is **javax.naming.NameNotFoundException: Name comp/env/jdbc not found in context "java:".**

What am I missing here? Even when I try to explicitly define the dataSource bean method in SampleApplication.java like below it fails with the same error.
#Bean
public static DataSource dataSource() throws NamingException {
JndiObjectFactoryBean jndiFactoryBean = new JndiObjectFactoryBean();
jndiFactoryBean.setJndiName("java:comp/env/jdbc/fileUploadDS");
jndiFactoryBean.setExpectedType(DataSource.class);
jndiFactoryBean.setLookupOnStartup(true);
jndiFactoryBean.setResourceRef(true);
jndiFactoryBean.afterPropertiesSet();
return (DataSource) jndiFactoryBean.getObject();
}
I referred this and it says we need to set enableNaming() on servlet container? Can I do something similar for non-embedded web application context? Or is it purely a WAS 8.5 issue??
You need to have resource reference with jdbc/fileUploadDS name in your web.xml. And make sure it is bound to actual datasource name during installation or via ibm-web-bnd.xml file.
Definition in web.xml:
<resource-ref>
<description />
<res-ref-name>jdbc/fileUploadDS</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>
If you dont want to use web.xml, then in normal Java EE app you could just add in web component (servlet, filter) the following class annotation:
#Resource(name="jdbc/fileUploadDS", type=javax.sql.DataSource.class, lookup="jdbc/fileUploadDS")
but I'm not Spring-boot expert, so don't know, if it will work or is possible there.
I am able to connect my Spring-Boot application (deployed in Websphere Application Server 9) to WAS datasource.
The following code worked for me, for connecting to DataSource:
#Bean(name = "WASDataSource")
public DataSource WASDataSource() throws Exception {
JndiDataSourceLookup dataSourceLookup = new JndiDataSourceLookup();
return dataSourceLookup.getDataSource("DSNAME");
}
#Bean(name = "WASDataSourceJdbcTemplate")
public JdbcTemplate jdbcTemplate_WASDS(#Qualifier("WASDataSource")
DataSource dsDB2) {
return new JdbcTemplate(dsDB2);
}
Note: The name of Datasource "DSNAME" is the name which appears on the UI of Websphere console.
You can see that via -> Select Resources > JDBC > Data Sources.
Then I created jdbc template:
#Autowired
#Qualifier("WASDataSourceJdbcTemplate")
private JdbcTemplate db2WASTemplate;`
And running query using the query method works fine :
db2WASTemplate.query()
I did not create any Web.xml or ibm-web-bnd.xml files
I just configured spring boot with my custom datasource as follows:
#Bean
#ConfigurationProperties("spring.datasource")
public DataSource dataSource() {
return DataSourceBuilder.create().build();
}
and inside the application.properties file I defined all datasource settings as usual
spring.datasource.driver-class-name= ***
spring.datasource.url= ***
spring.datasource.username= ***
spring.datasource.password= ***
spring.datasource.jndi-name=jdbc/myDB
It works nicely with #SpringBootApplication with all other default settings
I am facing the same problem. I don't know how to define tag in spring boot since there is no web.xml file in the spring boot.
So far what I came to know that we have to define it in the application file from where we start our spring application. I think we need to use this method to set the Datasource:
#Bean(destroyMethod="")
#ConfigurationProperties(prefix="datasource.mine")
public DataSource dataSource() throws Exception {
JndiDataSourceLookup dataSourceLookup = new JndiDataSourceLookup();
return dataSourceLookup.getDataSource("java:jdbc/configurationFile");
}
I have a RabbitMQ instance deployed on a google cloud engine. I also have a hadoop instance deployed on a different google cloud engine but still in the same application. I am trying to connect to the RabbitMQ queue instance from the hadoop clusters but with no success.
I have a java application that should push items on the RabbitMQ queue and then receive them in the same application. The following is the connection java code:
ConnectionFactory factory = new ConnectionFactory();
factory.setHost("130.211.112.37:5672");
try {
connection = factory.newConnection();
channel = connection.createChannel();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
but i get the following result:

I tried opening port 5672 on google cloud firewall. Does anyone has some pointers to the solution please?

As wrote to the comment:
ConnectionFactory factory = new ConnectionFactory();
//factory.setHost("130.211.112.37:5672"); <----- sethost accepts only the host!
factory.setHost("130.211.112.37");
factory.setPort(5672);
try {
connection = factory.newConnection();
channel = connection.createChannel();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
By default the port is 5672, so setPort it is not necessary.
You have to use setPort only if you change the default port.
As explained here: https://www.rabbitmq.com/api-guide.html you need to call setHost and setPort to create a connection. In your app you are passing the host and port together on the same line.
