Hi All,
I am encoutering the following exception:
java.lang.NullPointerException

I don't have a connection to a DB2 server at build time, but I would
like to generate the database schema, just like any of the other
drivers.
I think the problem comes from the following method:
public boolean isDB2ZOSV8xOrLater() {
boolean match = false;
if ((databaseProductVersion.indexOf("DSN") != -1
|| databaseProductName.indexOf("DB2/") == -1)
&& maj >= 8)
match = true;
return match;
}
if the driver is not connected, the metadata cannot be retrieved, so
it is obviously null.
Note that it would be great to get the indexes, as well:
public void createIndexIfNecessary(Schema schema, String table,
Column pkColumn) {
if (isDB2ZOSV8xOrLater()) {
// build the index for the sequence tables
// the index name will the fully qualified table name + _IDX
Table tab = schema.getTable(table);
Index idx = tab.addIndex(tab.getFullName() + "_IDX");
idx.setUnique(true);
idx.addColumn(pkColumn);
}
}
so, it'dbe nice to get rid of the guard to V8 or later in offline mode.
What do you think ?
Niko,
