Apache Axis Error - No Engine Configuration File

Question

We have an application running on WebSphere 6.1, and every couple of days we get the following in the logs:

org.apache.axis.ConfigurationException: No engine configuration file - aborting! at org.apache.axis.configuration.FileProvider.configureEngine(FileProvider.java:175) at org.apache.axis.AxisEngine.init(AxisEngine.java:172) at org.apache.axis.AxisEngine.(AxisEngine.java:156) at org.apache.axis.client.AxisClient.(AxisClient.java:52) at org.apache.axis.client.Service.getAxisClient(Service.java:103) at org.apache.axis.client.Service.(Service.java:112) 

If we restart the JVM, we will be fine for 2-3 days before we start again.

I saw another question on this site that describes a similar problem, and the answer for this was:

I solved this by copying the client_config.wsdd file to the WEB-INF / classes folder. Axis has not complained yet :)

However, as far as we know, we do not have a specific client_config.wsdd file, and we did not have to configure it. If something is missing, we will always get this error, but, as I mentioned above, this only happens every few days, and stopping the JVM fixes it a bit.
