Generate debug information at runtime

With the GREDEBUG environment variable, you can generate debug information at runtime.

Note:

If GREDATAFILE is set, no report is created and setting GREDEBUG has no effect.

The GREDEBUG environment variable defines the debug level for the Genero Report Engine. When this variable is set:

Error and warning messages are written to standard output.
Debug files are generated on disk.

Valid values are:

0: nothing
1: fatal only
2: fatal and error
3: fatal, error, and warning
4: fatal, error, warning, and info
5: fatal, error, warning, info, and debug
6: fatal, error, warning, info, debug, and trace
6+: all debug information

When debugging is enabled and you run the program, the report engine creates XML files called jdebug[0-9]?.xml that contain the xml stream as it leaves the various filters on the pipe. In distributed mode, these files are created on the server side.

Example jdebug.xml file

<?xml version="1.0" encoding="windows-1252"?>
<?PipeConfiguratorStyleSheet  reportFileName="../Sales/SalesList.4rp"
  preview="false" outputFileName="SalesList.pdf" outputDevice="PDF" 
  processArbitraryXMLInput="true" debugLevel="9"?>
