Symptoms

When publishing a process model as a web service, the model fails to start and the following error is seen in the application server log:

YYYY-MM-DD HH:MM:SS,mmm [ajp-/X.X.X.X:XXXX-XX] ERROR com.appiancorp.process.webservices.pmserver.PMServletDelegate - 
An unknown error occurred while consuming the PM WS for the service:

	... 91 more

Cause

The following are possible causes:

The error message indicates that this is not an issue with the process model published as a web service; it is an issue with a malformed SOAP Envelope that the invoker/client is sending to the model in order to invoke it as a Web Service. This is failing in the getEnvelope() method, which suggests the request sent is malformed. An XML Validator can confirm if it is a valid SOAP envelope.
The error message occurs due to the service sending a large amount of data. The web server truncates this amount of data for security reasons, which results in an invalid XML.

Action

To resolve the behavior, consider the following:

If there is an issue with a malformed SOAP Envelope, use an XML Validator to confirm the client is sending a valid SOAP envelope.
If the web server is truncating the request due to a large amount of data being sent, try sending a smaller request from the service.
To troubleshoot this further and analyze the SOAP envelope that Appian is receiving, add the following logger to <APPIAN_HOME>/ear/suite.ear/resources/appian_log4j.properties:

Cause

The following are examples of possible causes:

The error message indicates this is not an issue with the model published as a web service; it is an issue with a malformed SOAP Envelope that the invoker/client is sending to the model in order to invoke it as a Web Service. This is failing in the getEnvelope() method which suggests the request sent is malformed; an XML Validator can confirm if it is a valid SOAP envelope.
The error message occurs due to the service sending a large amount of data. The web server truncates this amount of data for security reasons which results in an invalid XML.

Action

To resolve the behavior, consider the following:

If there is an issue with a malformed SOAP Envelope, use an XML Validator to confirm the client is sending a valid SOAP envelope.

If the web server is truncating the request due to a large amount of data being sent, try sending a smaller request from the service.

To troubleshoot this further and analyze the SOAP envelope that Appian is receiving, add the following logger to ear/suite.ear/resources/appian_log4j.properties:

Symptoms

The following error is seen in the application server log:

YYYY-MM-DD HH:MM:SS,mmm [ajp-/X.X.X.X:XXXX-XX] ERROR com.appiancorp.process.webservices.pmserver.PMServletDelegate - 
An unknown error occurred while consuming the PM WS for the service:

	... 91 more

Cause

This message indicates this is not an issue with the model published as a web service; it is an issue with a malformed SOAP Envelope that the invoker/client is sending to the model in order to invoke it as a Web Service. This is failing in the getEnvelope() method, which suggests the request sent is malformed; an XML Validator can confirm it is a valid SOAP envelope.

This could also be due to the service sending a large amount of data and the web server is truncating it for security reasons resulting in an invalid XML.

Action

To alleviate the behavior, perform one of the following:

Use an XML Validator to confirm the client is sending a valid SOAP envelope.
Troubleshoot this further and analyze the SOAP envelope Appian is receiving, add the following logger to ear/suite.ear/resources/appian_log4j.properties:

log4j.logger.com.appiancorp.process.webservices=DEBUG

If sending a large amount of data, try with a smaller request.
