EXEC_COMMAND_EXECUTABLE
static final String EXEC_COMMAND_EXECUTABLE
The header value overrides the executable of the command, configured in the exec endpoint URI. As executable is considered the remaining of theExecEndpoint
URI;
e.g. in the URIexec:C:/Program Files/jdk/java.exe
,C:/Program Files/jdk/java.exe
is the executable.

- Constant Field Values
-
EXEC_COMMAND_ARGS
static final String EXEC_COMMAND_ARGS
The header value overrides the existing command arguments in theExecEndpoint
URI. The arguments may be aList
. In this case no parsing of the arguments is necessary.- See Also:
- Constant Field Values
-
EXEC_COMMAND_OUT_FILE
static final String EXEC_COMMAND_OUT_FILE
Specifies the file name of a file, created by the executable, that should be considered as output of the executable, e.g. a log file.
-
EXEC_COMMAND_WORKING_DIR
static final String EXEC_COMMAND_WORKING_DIR
Sets the working directory of theEXEC_COMMAND_EXECUTABLE
. The header value overrides any existing command in the endpoint URI. If this is not configured, the working directory of the current process will be used.- See Also:
- Constant Field Values
-
EXEC_COMMAND_TIMEOUT
static final String EXEC_COMMAND_TIMEOUT
Specifies the amount of time, in milliseconds, after which the process of the executable should be terminated. The default value isLong.MAX_VALUE
.- See Also:
- Constant Field Values
-
EXEC_STDERR
static final String EXEC_STDERR
The value of this header is aInputStream
with the standard error stream of the executable.- See Also:
- Constant Field Values
-
EXEC_EXIT_VALUE
static final String EXEC_EXIT_VALUE
The value of this header is the exit value that is returned, after the execution. By convention a non-zero status exit value indicates abnormal termination.
Note that the exit value is OS dependent.- See Also:
- Constant Field Values

EXEC_USE_STDERR_ON_EMPTY_STDOUT
static final String EXEC_USE_STDERR_ON_EMPTY_STDOUT
The value of this header is a boolean which indicates whether or not to fallback and use stderr when stdout is empty.- See Also:
- Constant Field Values
-
EXEC_COMMAND_LOG_LEVEL
static final String EXEC_COMMAND_LOG_LEVEL
