Hi,

I get the below error when i tried to restart my jboss server after  
integrating with elastic server. I am using elastic search 1.4 version. Can  
some one let me know where i am doing wrong. Elastic server absolutely work  
fine apart from below error.

public static Client getESClient() {  
if (esClient == null) {  
Client esClient = new TransportClient().addTransportAddress(new  
InetSocketTransportAddress("127.0.0.1", 9300));  
return esClient;  
}  
return esClient;  
}

Hi,

I used only one jar for elasticsearch i.e. elasticsearch-1.4.1.jar, i don't  
think we need any other jars apart from this and my elastic server is also  
running. Please let me know if there are any additional jars which i need  
to add.

Thanks,  
Vijaya

JBoss performed a double close in concurrency to ES which actually was  
still active in closing down itself. Check if you are using a

contextInitialized()/contextDestroyed() methods which are called by JBoss  
exactly once during the life cycle of a web application.

Hi Jorg,

I am not using ServletContextListener for client instance. I have shared  
the code above for creating client. But i am not closing the client. I  
tried closing the client that did not make any difference.

Thanks,  
Vijaya

Hi Joerge,

I have overridden Spring ContextLoadListener and tried to close the client  
instance on context destroyed, but i still get the same error.

MyAppContextLoadListener  
@Override  
public void contextInitialized(ServletContextEvent event) {  
super.contextInitialized(event);  
log.debug("My web app Loaded.......");

// You can get Servelte Context  
ServletContext servletContect = event.getServletContext();

WebApplicationContext webApplicationContext =  
WebApplicationContextUtils.getRequiredWebApplicationContext(servletContect);

// You can get any bean, which is defined in spring xml file here.  
ESClient esclient = ESClient.getInstance();  
client = esclient.getClient();  
}

```
@Override
public void contextDestroyed(ServletContextEvent event) {

```

super.contextDestroyed(event);  
client.close();  
}

I made ESClient.java singleton as below

public class ESClient {  
private Client client = null;  
private static ESClient esClient = null;  
/\*\*  
\*  
\*/  
private ESClient() {  
if (client == null) {  
/\*Settings settings =  
ImmutableSettings.settingsBuilder().put("transport.tcp.connect\_timeout",  
"1000").build();  
client = new TransportClient(settings).addTransportAddress(new  
InetSocketTransportAddress("127.0.0.1", 9300)); \*/  
client = new TransportClient().addTransportAddress(new  
InetSocketTransportAddress("127.0.0.1", 9300));  
}  
}  
public static ESClient getInstance( ) {  
if(esClient==null) {  
esClient = new ESClient();  
}  
return esClient;  
}

public Client getClient() {  
return client;  
}  
}

But i still get error saying

15:54:02,460 INFO [transport] [Tyr] failed to get node info for  
[#transport#-1][BLRD17730][inet[/127.0.0.1:9300]], disconnecting...  
java.lang.NoClassDefFoundError:  
org/elasticsearch/transport/SendRequestTransportException

Please let me know if i am doing anything wrong.

Thanks,  
Vijaya

From the code, it is not clear what cluster name is set in the settings.  
Using just new TransportClient() tries to connect to localhost port 9300  
with cluster name "elasticsearch", which is not correct in most custom  
environment.

Please check if cluster name setting is correct.

Hi David/Jorg,

I am using elastic server 1.4.1 version. I tried both using the default  
cluster and below cluster. both throwing same exceptions on starting jboss  
server, but search works fine.

Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name",  
"prbman").build();  
client = new TransportClient(settings).addTransportAddress(new  
InetSocketTransportAddress("[amadeus.com](http://amadeus.com)", 9300));

Thanks,  
Vijaya

Do you still get "Illegal access: this web application instance has been  
stopped already" ?

If so, you still have a double close problem on the web app management

container configuration. Without Spring, I do not have errors in JBoss.

Hi Jorg,

I changed the Cluster name and Node name, but still i get error  
SendRequestTransportException

Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name",  
"prbmanCluster").put("node.name",  
"PrbmanNode").put("transport.tcp.connect\_timeout", "1000").build();  
Client client = new TransportClient(settings).addTransportAddress(new  
InetSocketTransportAddress("BLRD17730", 9300));

After the above changes i get below error

14:34:28,516 INFO [transport] [PrbmanNode] failed to get node info for  
[#transport#-1][BLRD17730][inet[BLRD17730/172.22.220.125:9300]],

**Author:** ![jprante](https://sea2.discourse-cdn.com/elastic/user_avatar/discuss.elastic.co/jprante/32/44941_2.png) [@jprante](https://discuss.elastic.co/u/jprante)\
**Post date:** [January 1, 2015, 3:59pm UTC](https://discuss.elastic.co/t/getting-error-while-starting-server/21361/15 "2015-01-01T15:59:58Z")

</div>

I know the error for years, it is because JBoss web app has already removed  
the web app and destroyed the class loader for the web app including  
elasticsearch jars, but afterwards, the client threadpool is still up and  
closes itself.

It helps to explicitly close the thread pool

transportClient.threadPool().shutdownNow()

before

transportClient.close()

This means, all active connections of TransportCient must be finished  
before closing down. With the current API, it is not possible to let the  
TransportClient wait for the completion of outstanding actions (the  
BulkProcessor does this in the close() method). A workaround is to wait for  
30-60 seconds (depending on the responsiveness of the cluster) and then  
execute transportClient.threadPool().shutdownNow() + transportClient.close()

Interesting. That's surely something which worth being documented...

> This means, all active connections of TransportCient must be finished before closing down. With the current API, it is not possible to let the TransportClient wait for the completion of outstanding actions (the BulkProcessor does this in the close() method). A workaround is to wait for 30-60 seconds (depending on the responsiveness of the cluster) and then execute transportClient.threadPool().shutdownNow() + transportClient.close()

Check if you are using a ServletContextListener for the client instance. There are contextInitialized()/contextDestroyed() methods which are called by JBoss exactly once during the life cycle of a web application.
