Web DataWindow on EAServer
You can run the Web DataWindow server component on EAServer using PowerDynamo as the
dynamic page server. The component transaction server and the page
server can run on the same or on different computers.
Files required on the transaction
server
Two types of files are required on the transaction server:
- The PBLs or PBDs containing the definitions of your
DataWindow objects
Make sure they are installed in a directory in the server’s
path. If EAServer is running as
a service, they must be on the system path or the names of the PBLs
or PBDs must be fully qualified. - PowerBuilder runtime files (including PBVM90.DLL, PBJAG90.DLL, and PBDWE90.DLL on
Windows) and PBDWR90.PBD, which contains the
implementation of the DataWindow HTMLGenerator90 component
On Windows, a version of these files can be installed when
you install EAServer. For more
information about required files, see “PowerBuilder component on
EAServer “.
You also need to create a connection cache for the database
the component will access. For more information, see the DataWindow
Programmer’s Guide
.
Custom components You can create a custom version of the DataWindow component
and configure its properties for more efficient reuse. For more
information, see the DataWindow Programmer’s
Guide
.
Files required on the dynamic
page server
To use PowerDynamo as the page server and connect to the EAServer component using Java, the
following files are required on the PowerDynamo server computer:
HTML pages, templates, and scripts These are the files that you created for your application.
If you used a Web target to generate these files, you can use the
built-in deployment controller for PowerDynamo to install them.
For more information, see Working with Web and JSP Targets
.
EAServer client
software for Java The files listed in Table 39-18 are required on the PowerDynamo server.
| Name | Description |
|---|---|
| easclient.jar | Java class required for clients |
| easj2ee.jar | Java class required for J2EE support |
Sun Java Development Kit (JDK) Any versions of the JDK that were installed with EAServer are located in the SybaseSharedSun directory.
The JDK that is installed with PowerBuilder is located in the SybaseSharedPowerBuilder directory.
If you are using JDK 1.2 or 1.3, make sure that the JREinclassic subdirectory
of the JDK is listed in the system PATH environment variable.
If you are using JDK 1.4, make sure that the JREinclient subdirectory
of the JDK is listed in the system PATH environment variable.
In Sybase Central, verify that Sun Java VM is specified as
the Java VM in the General Settings folder in the PowerDynamo Configuration
utility. You must also define a mapping in Sybase Central that associates
the connection profile for your database with the Web site path
name you will use in the URL. For more information, see the PowerDynamo
User’s Guide
