Install Esper in Eclipse

Question

I'm struggling to install Esper in Eclipse. I'm not good at technical issues, so please I need all details to do so.

In fact, I added all jar files of esper-5.4.0.zip in Java build path of my project. I have got the following error messages:

log4j:WARN No appenders could be found for logger (com.espertech.esper.util.ObjectInputStreamWithTCCL).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
Exception in thread "main" com.espertech.esper.client.EPStatementException: Failed to resolve event type: Event type or class named 'Deposit' was not found [every A=Deposit]

Could you tell us where did you get the project zip and the other zip files you've used? If we are to help, we need to know this. — Sufian, Jun 28 '16 at 11:07
Hi, thanks. I got the project zip from this link: http://www.espertech.com/esper/download.php — user6519377, Jun 28 '16 at 12:20
Regarding Deposit, I have the following class: class Deposit{ private float amount; private String customerID; public String getCustomerID(){ return customerID; } public void setCustomerID(String customerID){ this.customerID=customerID; } public float getAmount(){ return amount; } public void setAmount(float amount){ this.amount=amount; } } — user6519377, Jun 28 '16 at 12:24

When you create a statement like select * from Deposit that requires that you tell the engine what a "Deposit" is. That is done by adding an event type.

The documentation and tutorials have plenty of introductory examples or you could review the examples that comes with the Esper download.
