How to init sequence on server to return to client?
How do I initialize a sequence to be returned to a
client from a java server?
sample idl :
module someModule {
typedef sequence<octet> Data;
struct SomeStructure {
Data file;
string info;
};
typedef sequence<SomeStructure> results;
interface someObject {
get(in string infotoget, out results results_out, out unsigned long
numberOfItems);
};
};
on client :
.
.
.
String info = "filename";
someModule.resultsHolder rh = new someModule.resultsHolder();
org.omg.CORBA.IntHolder ih = new org.omg.CORBA.IntHolder();
someObject.get(info,rh,ih);
on server :
?
I implemented a server, but I get the following error :
org.omg.CORBA.UNKNOWN:vmcid: SUN minor code: 202 completed: Maybe

I think the error is caused by incorrect implementation of the sequence on the server.
Here is the method implementation on the server side :
public void get(String toget, someModule.resultsHolder results_out, org.omg.CORBA.IntHolder numberOfItems)
{
System.out.println("inside get : " + toget);
someModule.SomeStructure[] srs_array = new someModule.SomeStructure[1];
srs_array[0].info = "EMPTY";
// create array for octet sequence
byte[] data_array = new byte[1];
data_array[0] = 0;
srs_array[0].file = data_array;
results_out = new someModule.resultsHolder(srs_array);
numberOfItems = new IntHolder(0);
}
