Problem in creation function interface in JCO program

Question

I am using BLOB /people/gregor.wolf3/blog/2004/08/26/setup-and-test-sap-java-connector-outbound-connection for making connection SAP & JAVA it is working properly and giving the same O/P as maintained in example. Now my requirement is that i want to use another JAVA program for outbound processing with SAP i mean....
I have a program by the name FetchMailUsage which is fetching mail from a perticular id. I m using this program in JCO program and when i m creating a function interface through bellow code , import export working well but when i m creating a table interface for that function it is giving short dump  in ABAP program jco.server could not find server function.
the code for function interface is
JCO.MetaData fmeta = new JCO.MetaData("CONNECTION");
   fmeta.addInfo("REQUTEXT", JCO.TYPE_CHAR, 255,   0,  0, JCO.IMPORT_PARAMETER, null);
   fmeta.addInfo("ECHOTEXT", JCO.TYPE_CHAR, 255,   0,  0, JCO.EXPORT_PARAMETER, null);
    fmeta.addInfo("RESPTEXT", JCO.TYPE_CHAR, 255,   0,  0, JCO.EXPORT_PARAMETER, null);
     fmeta.addInfo("RFCTABLE", JCO.TYPE_TABLE, 150, 0, 0, 0, "ZMTAB");
    repository.addFunctionInterfaceToCache(fmeta);
connection:- object of class FetchMailUsage
ZMTAB :- Table type placed in SAP have one field.
Anyone please tell me procedure which i m using is correct if not tell me the process by which i create table for function interface.

Answer 1

Hi Gregor ,
Thanks for your reply, it is solving my problem partially.By defining structure i am able to implement function interface with table but i want to pass some data through this table to ABAP.How i will pass data through table structure . is there any requirement to set value like this
ZIT_TAB.setValue(value,field name);
Actually when i am exicuting FM from ABAP it is not fatching data in table which i m passing.
I m sending my test code please correct where it is wrong.
<b>Function Interface with table structure:-</b>
JCO.MetaData fmeta = new JCO.MetaData("CONNECTION");
   fmeta.addInfo("REQUTEXT", JCO.TYPE_CHAR, 255,   0,  0, JCO.IMPORT_PARAMETER, null);
   fmeta.addInfo("ECHOTEXT", JCO.TYPE_CHAR, 255,   0,  0, JCO.EXPORT_PARAMETER, null);
    fmeta.addInfo("RESPTEXT", JCO.TYPE_CHAR, 255,   0,  0, JCO.EXPORT_PARAMETER, null);
     fmeta.addInfo("RFCTABLE", JCO.TYPE_TABLE, 150, 0, 0, 0, "ZIT_TAB");
    repository.addFunctionInterfaceToCache(fmeta);
JCO.MetaData smeta  = new JCO.MetaData("ZIT_TAB");
     smeta.addInfo("FIELD",   JCO.TYPE_BYTE,   3, 24, 0);
     repository.addStructureDefinitionToCache(smeta);
<b>code bywhich i m passing data through table</b>
FetchMailUsage CONNECTION = new FetchMailUsage();
CONNECTION.readMail();
output.setValue(CONNECTION.mimeType,"RFCTABLE");
<b>CONNECTION is object of my class FetchMailUsage</b>
<b>Function using in ABAP is :-</b>
CALL FUNCTION 'CONNECTION' DESTINATION 'JCO'
  EXPORTING
    requtext = requtext
  IMPORTING
    echotext = echotext
    resptext = resptext
  TABLES
    RFCTABLE = RFCTABLE  .
