Michael Martell updated GEODE-2910:
-----------------------------------
Description:
We had trouble passing objects to functions via the REST API because we had no
objects registered. The only documentation we found for passing objects was
[here|http://geode.apache.org/docs/guide/11/rest_apps/develop_rest_apps.html#topic_rbc_h25_m4]
where it says:
"... the Item domain object must be in the CLASSPATH of all members receiving
the function."
As a C# programmer, this is very confusing. Helpful to spell out that your C#
class needs to have a Java equivalent loaded in the server. Also that the
object type name includes the Java package name.
Adding the following simple example to the documentation would have been a
great demonstration of how objects are registered.
This Java class is required to register the Item object (referred to in the
link above) on the server:
{code}
package cheezypizza;
public class Item {
public int itemNo;
public String description;
public int quantity;
public float unitprice;
public double totalprice;
}
{code}
A script to register the objects:
{code}
# Build the jar
javac -classpath /mnt/c/gemfire/lib/\* -d ./out src/cheezypizza/*.java
cd out
jar cvMf functions.jar cheezypizza/*.class
# Copy jar to server
scp functions.jar $HOSTNAME:/home/user
# In gfsh, starting the server, specify --classpath=
start server --name=rest-server --start-rest-api=true --http-service-port=8080
--classpath=/home/user/functions.jar
{code}
