|Points out important notes.|
The Web browser-based access of HCL Z and I Emulator for Web gives your users a simple way to reach critical host data. Just click a hyperlink to launch the Z and I Emulator for Web Java(TM) applet. This Web-to-host connectivity solution helps provide secure Web-browser access to host applications, so you can take existing host applications to the Web without programming.
With support for TN3270E, TN5250, VT52, VT100, VT220, VT320, VT420 and CICS(R) Transaction Gateway access, along with Database On-Demand and FTP, users can have a single interface to their key host data. Because Z and I Emulator for Web is based on Java technology, its interface has the same look and feel across various operating environments.
Z and I Emulator for Web provides access to host applications from a Web browser. The browser downloads the Z and I Emulator for Web Java applet from the Web server and then connects to most standard Telnet servers to access host applications. With Z and I Emulator for Web, the client applet contains the emulation functionality. The host configuration information can be provided to the applet from an HTML file or by using the Z and I Emulator for Web configuration server.
Using Z and I Emulator for Web eliminates the need to deploy the software to individual user desktops. Users can connect directly to a host system, such as IBM iSeries or eServer i systems, without the need for extra hardware and software between the client and the Telnet server. You can install Z and I Emulator for Web on many server platforms, accommodating various-size organizations and branch offices.
As software updates occur, the latest version of HCL Z and I Emulator for Web is downloaded each time a user accesses the software, helping eliminate the need to install code on client workstations. With the cached client feature, users download only once, after the initial installation or once after a software update. Subsequent uses then originate from user hard drives, while code updates are handled in the background through the cached client. Users can be productive and have the newest version of code, with low distribution costs for your business.
The HCL Infocenter for Z and I Emulator for Web has more information on these packages:

Open a browser on a Windows machine and type the following address: http://hostname/zieweb/dashboard.html.If you see the Z and I Emulator for Web HTML page, the HTTP Web server has found the Z and I Emulator for Web publish directory.
Z and I Emulator for Web provides a sample HTML file generated by the Z and I Emulator for Web Deployment Wizard. This sample file provides 3270, 5250, VT, and FTP sessions, which include download client and Java auto-detection components.
Locate the ziewebclients.zip file on your Z and I Emulator for Web server in the /<ZIEWeb install directory>/ZIEWeb/samples/html directory.
Copy this zip file to your /<ZIEWeb install directory>/ZIEWeb directory.
If you would like to create your own Z and I Emulator for Web Deployment Wizard files, or use other Z and I Emulator for Web options, see the HCL Infocenter for Z and I Emulator for Web. Reference the information about using Z and I Emulator for Web clients.
Web pages from the Deployment Wizard can be distributed to servers using the DWunzip tool. DWunzip is located in the following directory on the iSeries or eServer i: /<ZIEWeb install directory>/lib/samples/DWunzip/ The file is called DWunzip-AS400.sh. To load the ziewebclients.zip file to the server using DWunzip, do the following:
Open the DWunzip-AS400.sh file. Verify that the runtime variables are correct and correspond with your environment. Change the default values of the runtime variables if they do not correspond with your environment.These include the following:
Confirm that DWunzip is authorized with the needed execute permissions and authorized to write to the publish directory on the server.
From the server OS command prompt, use the QSH command to run QSHELL.
|QSH commands are case-sensitive. You can print the QSH scroller to place the information into a job log for future reference.|
Run the DWunzip command file for your operating system, from the Z and I Emulator for Web published directory.
DWunzip-AS400 ziewebclientsHere, ziewebclients is the name of the sample file to be deployed, without the .zip extension or path. When DWunzip is running, it will display status messages, showing the files and folders that were extracted, overwritten, or created. It will also display a message when the command is complete. If you have run this tool once and are running it again on the same .zip file, you will be asked whether you want to overwrite the files. If you do not overwrite the files, the tool will close.
