Error in simple CQL

Question

I am trying to implement very simple CEP program.Cep is consist of the following component.
1.Jms adapter named MarketEventInputadapter,which is reading map message data from a simple queue.
2.one input channel named MarketEventInputchannel.
3.one processor named MarketEventprocessor containing CQL " <![CDATA[select * from MarketEventInputchannel[now]]]> ".
4.one output channel MarketEventOutputChannel.
5.one event bean MarketEventBean
while trying to deploy I am getting error as:
<Error> <Deployment> <BEA-2045016> <The application context "My_CEP" could not be started. Could not initialize component "MarketEventprocessor": Event property [cTimeStamp] defined in query [ExampleQuery] must exist in event type [MarketEvent]. Consider using the expression 'cTimeStamp AS ...' in the query.
I have use MarketEvent.java:
package com.bea.wlevs.example.algotrading.event;
public class MarketEvent {
     private Long TimeStamp;
     private String symbol;
     private Double price;
     private Long volume;
     private Long latencyTimestamp;
     * @return the latencyTimestamp
     public Long getLatencyTimestamp() {
          return latencyTimestamp;
     * @param latencyTimestamp the latencyTimestamp to set
     public void setLatencyTimestamp(Long latencyTimestamp) {
          this.latencyTimestamp = latencyTimestamp;
     * @return the timestamp
     public Long getTimestamp() {
          return TimeStamp;
     * @param timestamp the timestamp to set
     public void setTimestamp(Long TimeStamp) {
          this.TimeStamp = TimeStamp;
     * @return the symbol
     public String getSymbol() {
          return symbol;
     * @param symbol the symbol to set
     public void setSymbol(String symbol) {
          this.symbol = symbol;
     * @return the price
     public Double getPrice() {
          return price;
     * @param price the price to set
     public void setPrice(Double price) {
          this.price = price;
     * @return the volume
     public Long getVolume() {
          return volume;
     * @param volume the volume to set
     public void setVolume(Long volume) {
          this.volume = volume;
I have also use MarketEventBean.java:
package com.bea.wlevs.example.algotrading;
import com.bea.wlevs.ede.api.StreamSink;
import com.bea.wlevs.example.algotrading.event.MarketEvent;
public class MarketEventBean implements StreamSink {
     public void onInsertEvent(Object event) {
          if (event instanceof MarketEvent) {
               MarketEvent marketEvent = (MarketEvent) event;
               System.out.println("Price: " + marketEvent.getPrice());
Can anybody give an idea about the root cause of the error?

Answer 1

The root cause of this issue is the event property named timestamp. Timestamp is a CQL keyword and there appears to be a bug in the way we handle event property names that are CQL keywords.
One way to get around this is to use a different property name; for example, eventTimestamp. We will take a look at the bug and fix it. Could you open a service request so that it will be tracked? Thanks,
