redirectStandardStreams
public static void redirectStandardStreams() throws java.lang.Exception
Redirect the standard streams using the default platform character encoding.The JZOS batch launcher calls this method on startup to cause System.out, System.err and System.in to be directed to/from the job stream. Customers may also wish to use this method for the same purpose when Java is invoked without using the JZOS batch launcher. For example: from a COBOL main program that invokes Java code.
The I/O for will be redirected to DD:STDIN, DD:STDOUT, and DD:STDERR, using the same EBCDIC encoding that is specified by
getDefaultPlatformEncoding()
. These DDs must be allocated prior to calling this method, except that DD:SYSIN is optional. If the system property jzos.merge.sysout is set to true, System.out and System.err are redirected to DD:SYSOUT rather than DD:STDOUT and DD:STDERR respectively.This facility may only be used to redirect standard streams once, otherwise the results are not predictable.
- Throws:
java.lang.Exception
- if the streams could not be redirected.- See Also:
getDefaultPlatformEncoding()
-
redirectStandardStreams
public static boolean redirectStandardStreams(java.lang.String requestedEncoding, boolean enableTranscoding) throws java.lang.Exception
A static method which redirects the standard streams as follows:- System.out is redirected to DD:STDOUT (required)
- System.err is redirected to DD:STDERR (required)
- System.in is redirected from DD:STDIN (optional)
This method is invoked by the JZOS batch launcher to redirect the standard Java streams to MVS DDs. If STDIN is not defined, System.in is set to an InputStream that immediately returns -1 (EOS).
This facility may only be used to redirect standard streams once, and is NOT intended to be used from customer code.
If the system property jzos.merge.sysout is set to true, System.out and System.err are redirected to DD:SYSOUT rather than DD:STDOUT and DD:STDERR respectively.
- Parameters:
requestedEncoding
- the requested character encoding. If this encoding is not supported, defaultPlatformEncoding is used.- Returns:
true
if the requestedEncoding was used,false
if the default was used.- Throws:
java.lang.Exception
