server side
----------
at server side i loaded my data with person and also configured with my
database..
cache.loadCache(null,100_000);
cache.size();// It returns length of cache.
client side
----------
public static void main (String args[])
{
Ignition.setClientMode(true);
Ignite ignite=Ignition.start("ignite-example.xml");
IgniteCache<String, SessionManagementVO> cache =
ignite.getOrCreateCache("CacheName");
System.out.println(cache.size());// it also succesfully returns
same
length
executeTransaction(cache);// but her it shows error
}
private static void executeTransaction(IgniteCache<String, Person>
cache) {
try (Transaction tx = Ignition.ignite().transactions().txStart()) {
Person val = cache.get(2);// here it show error.
System.out.println("Read value: " + val);
tx.commit();
}
}
the error is:
