yes, i add more details :
///////////////////
when i tried this :
566 MOMutableTableRow l_row = (MOMutableTableRow)
ifTableEvatis.getModel().getRow(new OID("3"));
567 l_row.setValue(3, new Integer32(1));
i have this exception :
java.lang.NullPointerException at
sita.tsupervision.alarm.snmpAgent.setEvatisIstatus(snmpAgent.java:567)
When i use :
MOMutableTableRow l_row = (MOMutableTableRow)
ifTableEvatis.getModel().firstRow();
or
MOMutableTableRow l_row = (MOMutableTableRow)
ifTableEvatis.getModel().lastRow();
it's ok, but i want to set the value of row 3 and colum 3.
///////////////////
when i tried this :
Iterator<MOTableRow> it = ifTableModule.getModel().iterator();
it.next();
it.next();
MOMutableTableRow mot = (MOMutableTableRow) it.next();
mot.setValue(3, new Integer32(1));
i have this exception :
java.lang.ArrayIndexOutOfBoundsException: 3
at
org.snmp4j.agent.mo.DefaultMOMutableRow2PC.setValue(DefaultMOMutableRow2PC.java:74)
at
sita.tsupervision.alarm.snmpAgent.setEvatisIstatus(snmpAgent.java:561)
My table have 5 rows with 4 colums as :
private static DefaultMOTable createModuleTable() {
MOTableSubIndex[] subIndexes = new MOTableSubIndex[] { new
MOTableSubIndex(
SMIConstants.SYNTAX_INTEGER) };
MOTableIndex indexDef = new MOTableIndex(subIndexes, false);
MOColumn[] columns = new MOColumn[3];
int c = 0;
columns[c++] = new MOColumn(c, SMIConstants.SYNTAX_INTEGER32,MOAccessImpl.
ACCESS_READ_ONLY);// module number
columns[c++] = new MOColumn(c, SMIConstants.SYNTAX_OCTET_STRING
,MOAccessImpl.ACCESS_READ_ONLY);// module name
columns[c++] = new MOColumn(c, SMIConstants.SYNTAX_INTEGER32,MOAccessImpl.
ACCESS_READ_ONLY);// module status
ifTableModule = new DefaultMOTable(new OID("1.3.6.1.4.1.881.5.3.200.1.2.1"
),indexDef, columns);
model = (MOMutableTableModel) ifTableModule.getModel();
rowValues2 = new Variable[] { new Integer32(1), new OctetString("EVATIS-M"
), new Integer32(0) };
rowValues3 = new Variable[] { new Integer32(2), new OctetString("EVATIS-B"
), new Integer32(0) };
rowValues4 = new Variable[] { new Integer32(3), new OctetString("EVATIS-I"
), new Integer32(0) };
rowValues5 = new Variable[] { new Integer32(4), new OctetString("CATS-A"),
new Integer32(0) };
rowValues6 = new Variable[] { new Integer32(5), new OctetString("CATS-D"),
new Integer32(0) };
model.addRow(new DefaultMOMutableRow2PC(new OID("1"), rowValues2));
model.addRow(new DefaultMOMutableRow2PC(new OID("2"), rowValues3));
model.addRow(new DefaultMOMutableRow2PC(new OID("3"), rowValues4));
model.addRow(new DefaultMOMutableRow2PC(new OID("4"), rowValues5));
model.addRow(new DefaultMOMutableRow2PC(new OID("5"), rowValues6));
ifTableModule.setVolatile(true);
return ifTableModule;
}
I think this table is correctly implemented, beacause i can walk the table
with the default values.
I can set the first row and the last row.
But i dont understand how to update the row 3 ...
I prefer the first usage with getRow method beacause the iterator is not
easy to use.
Thank you for your help Franck .

HELP ME!
Hello Jean,
Both ways should work. As you did not share
which exceptions occur and how your rows
have been initialized, we cannot help
further.
Regards,
Frank
