Learn Java or get used to reading it
Talend ESB is a code generating piece of software. Sometimes when you have a bug in your Route it will be because of how the code is generated. Maybe the way the components have been connected is not handled very well or it doesn’t make sense for you to connect the components that way according the Camel Framework.
The best way to identify these issues and find workarounds is to be able to read the Java error stack and use it to point you toward the line of code that is at fault in the generated code (by using the Code tab). This will save hours of searching forums.
