For details about running the jadclient program to execute a non‑GUI application within your JADE code, see "Running a Non-GUI Client Application using jadclient". (For details about collecting command line arguments into a huge string array that is passed to the initialize method of the application, see "Running a JADE Non-GUI Client Application with Parameters", in the following topic.)
To run a non-GUI application defined in your JADE schema, specify the following arguments in the jadclient program.
jadclient path=database-path ini=jade-initialization-file schema=schema-name app=application-name startAppParameters [command-line-arguments]
Enclose any command line arguments that contain spaces in double (" ") or single (' ') quotation marks.
Command line arguments specified after the
method-name(initializeParameter: Object);
An exception is raised if the initialize method does not have one parameter only, of type
If you do not specify any command line arguments, the initialize method signature of your application should not have any parameters. Each argument is limited to the maximum size of a string in a huge string array, which is currently 2047 characters.
The jadclient program treats processing arguments enclosed in double (" ") or single (' ') quotation marks after the startAppParameters argument as single‑string entries in the huge string array. The handling of strings in this huge string array is application‑specific. For example, path= "program files" is treated as a two-string entry and "path= program files" is treated as a one‑string entry. How these entries are handled is determined by your application.
The following example shows an
jadclient(obj: Object); vars cmdLine : HugeStringArray; count : Integer; begin if obj = null then write "No command line"; else cmdLine := obj.HugeStringArray; foreach count in 1 to cmdLine.size do write "Arg[" & count.String & "] = '" & cmdLine[count] & "'"; endforeach; endif; terminate; end;
The following example shows the use of the jadclient program to output six arguments to the Jade Interpreter Output Viewer, based on the Application::jadclient method in the previous example.
c:\jade\bin\jadclient path=c:\jade\system ini=c:\jade\system\jade.ini schema=TestClient app=TestClientA startAppParameters 1 2 three ix "a b" "Second string but not in the violas "
The command line arguments in this example are passed as a huge string array to the Application::jadclient method in the example earlier in this subsection, resulting in the following displayed in the Jade Interpreter Output Viewer.
Arg[1] = '1' Arg[2] = '2' Arg[3] = 'three' Arg[4] = 'ix' Arg[5] = 'a b' Arg[6] = 'Second string but not in the violas'
