10.18 Deciphering Nested Stack Errors

A nested stack error, also called a nested exception, is basically an error that has been wrapped by another error, which is standard with Java and other languages to help provide more context to the issue. You can usually find the nested exception by locating the caused by string in the stack trace as shown in bold in the following example. If there is not enough information provided by the Oracle I/PM error, look deeper into the error message to see if other components are involved. Oracle I/PM uses nested stack errors to display repository related problems, BPEL issues, or problems caused by other components. After you locate the possible initial error, check the diagnostic logs for more troubleshooting information.

In the following example, the TCM-00787 error is occurring because the default provider within the Oracle Content Server repository was corrupted and reset (see boldface text).
