After you develop a connector, you can debug the connector code to identify and resolve issues such as connection failures, authentication errors, or logic flaws in the connector’s implementation.
You can attach a debugger to the connector code to pause execution at key points, inspect
variable values, and trace the code flow in real time, significantly enhancing the
accuracy and efficiency of identifying issues.
To debug the connector code, perform the following steps:
Click
Test Connection
.
In
Virtual Machine Parameters
field, set
suspend=y
and
address=8000
to suspend the connection process before you attach the debugger.
Open the relevant Java source file in the Eclipse IDE. For example,
<connectorName>Connection.java
.
Right-click and select
Toggle
Breakpoint
to add breakpoints at the specific lines of code where
you want to pause execution and inspect variables, such as the
openConnection
method.
Click
Run
Debug Configurations
.
Double-click
Remote Java Application
and select your connector project.
In the
Port
field, enter
8000
. The port number must be the same that you specified in the address parameter in Step 2. Default is 8000.
On the
Source
tab, click
Add
.
Select
Java Project
, and then click
OK
.
Select the Java projects that contain your connector's source code to ensure the debugger can find the source files, and then click
OK
.
Click
Apply
to save the configuration.
Click
Debug
to attach the debugger and start the remote debugging session.
The
Confirm Perspective Switch
dialog box appears.
Click
Switch
to switch to debug perspective.
You can use the debug perspective to control program execution, inspect variables, monitor threads, and manage breakpoints.
