Dear All,

having a problem with XLConnect I wonder, if one can change the
error-tolerance of ESS.
My present problem is that executing library(XLConnect) in R 4.4.2 on
Windows leads to an immediate end of the R-session if done in emacs 26.3
with ESS 18.10.2 .
If executed with rterm.exe XLConnect is loaded without any error or
warning message.
After a call like
wb <- loadWorkbook("writeWorksheet.xlsx", create = TRUE)
the following messages are displayed:

2025-01-21T19:35:19.801Z main ERROR Unable to locate configured
LoggerContextFactory
org.apache.logging.log4j.simple.SimpleLoggerContextFactory
2025-01-21T19:35:19.801Z main ERROR Log4j2 could not find a logging
implementation. Please add log4j-core to the classpath. Using
SimpleLogger to log to the console...

but the call is executed without problems. Obviously rterm.exe tolerates
the error. Is there some setting for ESS to behave as rterm.exe?

It would, of course, be desirable to eliminate the error, but I did not
succeed. And seemingly XLConnect works as expected despite the error
message.

best regards,

Heinz
