tESBProviderRequest: 'Port 80 already in use'

[TalendSolutionExpert]

Problem Description

When running a Job designed with a tEsbProviderRequest component, you may encounter the following exception:

Exception in thread "Thread-1" java.lang.IllegalArgumentException: Cannot start provider with uri: /gefService/. Port 80 already in use.
at dsi_test.gef_0_1.Gef$HandlerThread_tESBProviderRequest_1.run(Gef.java:814)

Root Cause

In this case, the Job is corrupted.

Solution

To fix the issue, follow these steps:

1. Ensure that the WSDL file being used is using port 80, and that the port is available for bidirectional communication.

2. Then, if you are still encountering the issue; check if the Job is migrated from lower environments to the latest version, if so, perform the following steps:

   1. Delete the existing WSDL file under Services.

   2. Delete the entire Job.

   3. Restart Talend Studio.

   4. Create a new WSDL file under Services.

   5. Create a new Job.
