The Viewer Java SDK allows you to create web applications that can both display Crystal reports and export them to other formats.
This section first provides a brief description of the individual features available to the viewer. The section then provides information about the various formats to which the SDK can programmatically export Crystal reports.

Crystal Reports provides a wealth of features for data analysis and presentation. Ideally, these features should be preserved when a report is viewed through a web browser. The viewer included with Crystal Reports for BEA WebLogic Workshop allows you to view reports through the web, while maintaining core report features and functionality. The viewer provides thin
The viewers included with Crystal Enterprise and Report Application Server provide additional support for the more advanced features provided by Crystal Reports. For more information on the features supported by these viewers, see Additional viewer features.

The following list presents several common usage scenarios for the viewer.
The Viewer Java SDK can be used to enable locale
This is only required when these components are used as report sources.
Although some of the report contents (such as currency symbols and DateTime formatting) also rely on a locale setting, this setting does not need to be the same as the locale setting on the RAS server or Page Server. In other words, client locale settings are used when locale
Tip: It is possible for the web browser's default language setting to be different from the system regional setting. For example, the system regional setting may be Chinese, but if the browser default language setting is English, the viewer is displayed in English.
To set the proper locale for the browser, select Internet Options from the Tools menu of Microsoft Internet Explorer, and click the Languages button. Move the language you want to use to the top of the list. To set the system regional setting, consult the documentation for your operating system.
A powerful feature that the viewer provides is the ability to export Crystal report files to a variety of different formats. Reports can be viewed before being exported to a different format for either viewing on a local machine or for distributing. The SDK provides the ability to programmatically export a report in addition to the ability to export the report through the HTML viewer.
This table shows the export formats that are supported by the SDK.
Format Type | Export Format |
---|---|
While you can export a Crystal report to another format, you cannot do the reverse. For example, you cannot use the viewers SDK to transform an RTF file into a Crystal report.
The viewer provided with Crystal Reports for BEA WebLogic Workshop is complimented by other feature
Searches report fields using Boolean and comparison operators.
Allows embedded maps to be viewed, and drilled down upon. This feature requires the mapping DLLs to be installed on the RAS server.
Produces output for mobile devices.
Produces output for PDA devices.
Allows individual report parts, such as charts, text, and fields, to be viewed.
The viewers included with Crystal Enterprise and the Report Application Server also provide support for additional report export formats, including Microsoft Word, Microsoft Excel, plain text, and character separated values.
Finally, these viewers support a special featuresmart tag parsing. Crystal Reports smart tags allow you to integrate Crystal reporting technology into Microsoft Office XP documents. Users can embed a link to a report from Office XP programs by copying and pasting a report part into an Office XP document.
