Passing input array from sqlplus or shell script

All,

I have a stored procedure which is usually called from a java program.  One of it's input parameters uses a user-defined type called EVENTARRAY which is created as such:

CREATE TYPE eventarray as table of varchar2(256);

The stored procedure parameters are defined as:

procedure mmjacdagentinfo(v_tenantid IN VARCHAR2,

v_queuetn IN VARCHAR2,

v_extlist IN eventarray,

v_stimestamp IN VARCHAR2,

v_etimestamp IN VARCHAR2,

cv_timeanswered OUT sap_types.GenericCurType)
as ....

I would like to test this by running the stored procedure from sqlplus or from a shell script instead of from the java program, but I can't figure out how to input the values for the v_extlist array variable.  (I can use either Solaris or Linux servers to test this.)  Can anyone help me?
