Question

I had an exception where I got this shortened trace:

Root Exception stack trace:
java.sql.SQLException: Invalid column name
    at oracle.jdbc.driver.OracleStatement.getColumnIndex(OracleStatement.java:3677)
    at oracle.jdbc.driver.OracleResultSetImpl.findColumn(OracleResultSetImpl.java:2749)
    at oracle.jdbc.driver.OracleResultSet.getString(OracleResultSet.java:494)
    + 3 more (set debug level logging or '-Dmule.verbose.exceptions=true' for everything)

I then put this in “log4j.properties” and it didn’t help:

log4j.logger.org.mule=DEBUG

I also failed with the second suggestion (and I suspect I’m not doing it right):

$ ./mule -Dmule.verbose.exceptions=true

Answer 1

As explained here, arguments are passed from the command line to Mule that way:

$ ./mule -M-Dmule.verbose.exceptions=true

ie. prefixed by -M.
