问题 I am working with Apache Camel Spring Framework. I have a component FTP (to get files from ftp) and Bean (process files and store it in database). All I have missing is when I process those files and store it in database I have to check if insert or update was successful (this is working too).

问题 I am using QuickFix/J 1.6.4 in a camel-quickfix component. Sometimes, I get the CannotSendException and it is not clear, what the exception cause is. I looked at the code, but there it seems that this exception is thrown, when the message could not be send - regardless of the reason. So how do I have to handle this exception?

问题 I am using QuickFix/J version 1.6.4 within Apache Camel 2.17.0 and I get the session message Disconnecting: Encountered END_OF_STREAM . It is not an error, but in my case it leads to an unintentional Logoff . What circumstances can lead to this message and how do I analyze which circumstance in my case is the cause? 回答1: I found the answer of this question in this blog post by bhageera .

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question?
