Release 10.1A: OpenEdge Development:
Java Open Clients

Connecting to the AppServer

To establish a connection to an AppServer using the Java OpenAPI, you must instantiate a com.progress.open4gl.javaproxy.OpenAppObject. You can create an OpenAppObject using one of the following constructors:

Syntax

public OpenAppObject (Connection connectObj, String appservice) public OpenAppObject (String url, String userid, String password,      String appserver-info, String appservice) public OpenAppObject (String userid, String password,      String appserver-info, String appservice) public OpenAppObject (String appservice)

connectObj

Specifies a com.progress.open4gl.javaproxy.Connection object, which defines connection parameters to access the AppServer. For more information on this object, see Chapter 3, " Connecting to an AppServer."

appservice

Specifies the name of the application service provided by the AppServer.

url

Specifies the URL to connect to an Appserver URL. Defaults to AppServer://localhost:5162/appService. For more information on the AppServer URL connection parameter format and default connection information, see the sections on connecting to an AppServer using a URL in OpenEdge Application Server: Developing AppServer Applications .

userid

Specifies a user ID required to access the AppServer.

password

Specifies a password required to access the AppServer.

appserver-info

Specifies information required by the application service at connection time.

You can set a number of session and run-time properties to manage access to an application service. For example, to access a session-free AppServer using the Java OpenAPI, you must set the proxy property PROGRESS.Session.sessionModel to 1. For more information on setting this and other session properties see Chapter 7, " Accessing Proxy Properties.".
