How do you wire PdxSerializer on the server side?
you might want to check

for pdx configuration either through code or pure gfsh.

pdx serializer, need help
hi,
I try to use pdx serializer for a very simple class. After I deploy it to
server, the gfsh query prompt me. Really can not see where can go wrong. Can
someone give suggestion?
Btw, from client side, it works fine as this.
public class Get {
public static void main(String[] args) throws InterruptedException {
Properties prop = new Properties();
prop.setProperty("conserve-sockets","false");
ClientCache cache = new
ClientCacheFactory(prop).addPoolLocator("centos", 10334)
.setPdxSerializer(new MyPdxSerializer())
.set("log-level", "info")
.create();
ClientRegionFactory<String, Simple> regionFactory =
cache.createClientRegionFactory(ClientRegionShortcut.PROXY);
Region<String, Simple> region = regionFactory.create("test");
Simple s = region.get("key1");
System.out.println("====================:" +s.getId() +" "+ s.getName()
+ " " + s.getTime());
}
}
Thanks a lot.
Nan
On the server query, it breack…
gfsh>query --query="select * from /test"
Result : false
startCount : 0
endCount : 20
Message : Could not deserialize pdx because the pdx serializer's fromData

Here is my class
