Otto,
I don't know how you can process a java array using RPG, I think you will
have to create a method in your java class to access the elements of the
java array.
Not quite the same, but when I wanted to pass an array of objects as an
object parameter to a java class,
the way I did it was create a java method to load one java array into
another java array.
* new java object
Dnew_string PR O EXTPROC(
D *JAVA:
D 'java.lang.String':
D *CONSTRUCTOR)
D CLASS(
D *JAVA:
D 'java.lang.String')
D bytes 65535A const varying
* loadTo java method
DloadTo PR O EXTPROC(*JAVA:class:
D 'loadTo')
D static
D CLASS(*JAVA:'java.lang.Object')
D O CLASS(*JAVA:'java.lang.Object')
D dim(15)
D const
* java string array object
Dattachments S O CLASS(
D *JAVA:'java.lang.String')
D DIM(30)
// For each attachment
For Z = 1 to NbrFiles;
If AttachFile(Z) <> '*NONE';
attachments(Z) = new_string(%trim(AttachFile(z)));
Endif;
Endfor;
args(8) = loadAtt(attachments);

Subject: Java array in ILE RPG
Hello,
I have run out of ideas how to sort out this problem:
I call a Java method getRSRows in my RPG program that returns an array of
objects; what I need is
Number of returned objects in the array.
Here are several code snippets from my program (I used IBM manual ILE RPG
Programmer's Guide - chapter RPG and Java to write the program). I tried to
pick up the fragments that I believe are relevant to the problem:
d GetCustomerAccountsImpl...
d S O
class(*JAVA:'classes.GetCustomerAccountsImpl')
d RSRows...
d S O
class(*JAVA:'classes.GetCustomerAccountsRSRowImpl')
d dim(10)
d getRSRows...
d PR O extproc(*JAVA:
d 'classes.GetCustomerAccountsImpl':
d 'getRSRows')
d
class(*JAVA:'classes.GetCustomerAccountsRSRow')
d dim(10)
...
RSRows = getRSRows(GetCustomerAccountsImpl); // this row works OK - Java
returns X objects - rows
// but the pgm fails-JVM even ends abnormally on getOuacct method in
for-loop
// if it runs i = X+1 (let's assume X is allways less than 10):
For i = 1 to 10;
Acct = %dec(getOuacct(RSRows(i)));
if Acct = 0.;
leave; // (i-1)=X is Number of objects in the array (??)
endif;
endfor;
And Java documentation contains:
CLASS: classes.GetCustomerAccountsImpl
method summary:
...
classes.GetCustomerAccountsRSRow[] getRSRows()
...
CLASS: classes.GetCustomerAccountsRSRowImpl
INTERFACE: GetCustomerAccountsRSRow
All Known Implementing Classes: classes.GetCustomerAccountsRSRowImpl
method summary:
...
long getOuacct()
....
Thanks for help and sorry about my English.
