Host Access Class Library for Java

What's New in Host Access Class Library for Java

The following new features are included in this release (9th edition) of the Host Access Class Library for Java:

• The ECLSession and ECLConnection classes now include methods to enable or disable support for the display of Unicode data in 5250 Display sessions.
  • OS/400 V5R2 supports display of Unicode characters using Coded Character Set Identifiers (CCSID).
  • Host On-Demand Version 8.0 supports this feature on 5250 Display Sessions.
• The package ECL has been extended to support SSH (Secure SHell) on VT sessions. This release supports a subset of SSH version 2.0 protocol. For more detailed information on SSH protocol, please refer to IETF Secure Shell (secsh) Charter home page at http://www.ietf.org/html.charters/secsh-charter.html .
  • Java 2 and Java Cryptography Extension (JCE) are required to run SSH in HACL. JCE is included in Java 1.4 and later.
  • SESSION_SECURITY_PROTOCOL must be set to SESSION_PROTOCOL_SSH.
• The ECLSession class now includes several properties for Web Express Logon (SSO_).
• The ECLPS class now includes MagStripeReader and BadgeReader methods, each with 3 method signatures. These methods allow Host On-Demand to handle Magnetic Hand Scanners, Magnetic Card Readers, and Optical Scanners in 3270 sessions as described in 3270 Information Display System Data Stream Programmer's Reference (GA23-0059-07), Chapter 7.
• For bidirectional support, methods were added to support bidirectional processing for methods like GetString, SearchString, and SetText. These methods are available via the ECLPSBIDIServices interface for 3270 Display and 5250 Display sessions and via the PSVTBIDIServices interface for VT Display sessions.
• The ECLSession class and the ECLConnection class now include methods for specifying backup Telnet servers. These methods let you specify up to two backup Servers (along with LUs/pools and ports) for the following session types: 3270 Display, 3270 Printer, 5250 Display, and 5250 Printer, CICS Gateway, and VT Display.

Features added in the 8th edition

The following new features were included in the 8th edition of the Host Access Class Library for Java:

• Run applet improvements

  Current user applets must implement ECLAppletInterface, which provides access to an active ECLSession at run-time. This new facility adds CustomInterface, which provides user applets with access to the Host On-Demand components HostTerminal, Applet instance, and Frame.

  For details about the new components, see Host Access Class Library for Java .

• Passing parameters to applets

  Parameters can now be passed to applets.  The applet needs to implement the public method initParam(). For more information, see Writing Your First Host Access Class Library Applet.

• Macro variable support

  The package ECL.screenreco has been extended to allow manipulating variables during macro play. 

• Proxy server support

  The package ECL has been extended to support HTTP and Socks proxy servers.

• Host printing support

  The package ECL has been extended to provide host printing functionality.
