Subject How can I insert data in Solr from Camel ?
Date Wed, 10 Aug 2011 04:01:18 GMT
Hi,

I tried inserting data into Solr through Camel using two ways:
1 - from the *processor*, calling Java code that inserts data to Solr
2 - using the Solr component from this website:
http://46.252.16.133/?q=espace/ispace/solrcomponent

In both cases, I ran into exceptions that prevented the program from
inserting data into Solr. 
*In Case 1* - simply by calling code executing
                 solrServer = new
CommonsHttpSolrServer("http://localhost:8983/solr");
it gave the following exception

SEVERE: Failed delivery for exchangeId: ID-myId. Exhausted after delivery
attempt: 1 caught: org.apache.camel.CamelExecutionException: Exception
occurred during execution on the exchange:
Exchange[/home/tnedelescu/Logs_fresh/inDir/file.txt]
org.apache.camel.CamelExecutionException: Exception occurred during
execution on the exchange:

	at java.net.URLClassLoader.defineClass(URLClassLoader.java:277)
        ...................

*In Case 2*, I got the following error:
SEVERE: Failed delivery for exchangeId: ID-myId. Exhausted after delivery
attempt: 1 caught: org.apache.camel.CamelExecutionException: Exception
occurred during execution on the exchange: Exchange[null]
org.apache.camel.CamelExecutionException: Exception occurred during

org.apache.camel.util.ObjectHelper.wrapCamelExecutionException(ObjectHelper.java:1155)
	at
org.apache.camel.impl.DefaultExchange.setException(DefaultExchange.java:271)

I tested that exchange.getOut().getBody() is not null when it exits
"proces(exchange)".

If anybody inserted data to Solr, at the same time involving Camel, please,
let me know how to do it. 

Thank you,
Tereza
