Thanks a lot. Below is the code am using and I get this error message. Not sure what is missing.
from("file:C:\\camelProject\\data\\inbox\\") .log("Starting to process big file: ${header.CamelFileName}") .split(body().tokenize("\n")).streaming() .unmarshal(csv).convertBodyTo(List.class) .bean(Parser1.class,"create_fp_record1") .aggregate(constant(true), new MyAggregationStrategy()).completionSize(2000) .to("file:C:\\camelProject\\data\\outbox\\?fileExist=Append&fileName=${file:onlyname.noext}"); public String create_fp_record1(List<String> marsRecord) { log.debug("START to parse record: "); StringBuilder str = new StringBuilder(300); str.append("L2|"); str.append(marsRecord.get(1)); str.append(delimeter); . . . . . str.append(delimeter); str.append("xx"); log.debug("END parse record"); return str; I see these logs as well as the Error log below. Not sure how these become null. 2011-11-08 13:42:35,827 DEBUG [Camel (camel-1) thread #0 - file://C:camelProjectdatainboxmars] bean.BeanProcessor - Setting bean invocation result on the IN message: L2|204043110533530 2011-11-08 13:42:35,827 INFO [Camel (camel-1) thread #0 - file://C:camelProjectdatainboxmars] converter.AnnotationTypeConverterLoader - Found 3 packages with 15 @Converter classes to load 2011-11-08 13:42:35,827 INFO [Camel (camel-1) thread #0 - file://C:camelProjectdatainboxmars] converter.DefaultTypeConverter - Loaded 154 core type converters (total 154 type converters) 2011-11-08 13:42:35,827 DEBUG [Camel (camel-1) thread #0 - file://C:camelProjectdatainboxmars] converter.DefaultTypeConverter - Loading additional type converters ... 2011-11-08 13:42:35,827 DEBUG [Camel (camel-1) thread #0 - file://C:camelProjectdatainboxmars] converter.AnnotationTypeConverterLoader - Loading file META-INF/services/org/apache/camel/TypeConverter to retrieve list of packages, from url: jar:file:/C:/Exec/apache-camel/lib/camel-spring-ws-2.8.1.jar!/META-INF/services/org/apache/camel/TypeConverter 2011-11-08 13:42:35,827 DEBUG [Camel (camel-1) thread #0 - file://C:camelProjectdatainboxmars] converter.AnnotationTypeConverterLoader - Loading file META-INF/services/org/apache/camel/TypeConverter to retrieve list of packages, from url: jar:file:/C:/Exec/apache-camel/lib/camel-spring-integration-2.8.1.jar!/META-INF/services/org/apache/camel/TypeConverter 2011-11-08 13:42:35,842 DEBUG [Camel (camel-1) thread #0 - file://C:camelProjectdatainboxmars] converter.AnnotationTypeConverterLoader - Loading file META-INF/services/org/apache/camel/TypeConverter to retrieve list of packages, from url: jar:file:/C:/Exec/apache-camel/lib/camel-core-2.8.1.jar!/META-INF/services/org/apache/camel/TypeConverter 2011-11-08 13:42:35,842 DEBUG [Camel (camel-1) thread #0 - file://C:camelProjectdatainboxmars] converter.AnnotationTypeConverterLoader - Loading file META-INF/services/org/apache/camel/TypeConverter to retrieve list of packages, from url: file:/C:/MyWorkspaces/camelTest/src/resources/META-INF/services/org/apache/camel/TypeConverter 2011-11-08 13:42:35,842 INFO [Camel (camel-1) thread #0 - file://C:camelProjectdatainboxmars] converter.AnnotationTypeConverterLoader - Loaded 2 @Converter classes 2011-11-08 13:42:35,842 DEBUG [Camel (camel-1) thread #0 - file://C:camelProjectdatainboxmars] impl.DefaultPackageScanClassResolver - Searching for annotations of org.apache.camel.Converter in packages: [com.verizon.learn.camel.utils] 2011-11-08 13:42:35,842 DEBUG [Camel (camel-1) thread #0 - file://C:camelProjectdatainboxmars] impl.DefaultPackageScanClassResolver - Found: [class com.verizon.learn.camel.utils.NamesConverter] 2011-11-08 13:42:35,842 INFO [Camel (camel-1) thread #0 - file://C:camelProjectdatainboxmars] converter.AnnotationTypeConverterLoader - Found 1 packages with 1 @Converter classes to load 2011-11-08 13:42:35,842 DEBUG [Camel (camel-1) thread #0 - file://C:camelProjectdatainboxmars] converter.DefaultTypeConverter - Loading additional type converters done 2011-11-08 13:42:35,842 INFO [Camel (camel-1) thread #0 - file://C:camelProjectdatainboxmars] converter.DefaultTypeConverter - Loaded additional 6 type converters (total 160 type converters) in 0.015 seconds 2011-11-08 13:42:35,842 DEBUG [Camel (camel-1) thread #0 - file://C:camelProjectdatainboxmars] aggregate.AggregateProcessor - Aggregation complete for correlation key true sending aggregated exchange: Exchange[Message: null -- View this message in context: http://camel.465427.n5.nabble.com/correlationExpression-while-Aggregating-tp4975191p4975364.html Sent from the Camel - Users mailing list archive at Nabble.com.
