JASPERSERVER TUTORIAL PDF

Kazrarisar The JasperReports Server application can be customized to match the appearance of another application and rebrand the user interface. Can anyone help me with a good tutorial on Jasper report server. Selecting the fields, and setting properties as shown below. Themes are stored in the repository and are part of the JasperReports Server UI framework that provides separation of structure, presentation, and events.

When declaring the content and layout of a report section in an XML report design we use the generic element. This is how a page header declaration should look.

This was achieved by putting a rectangle behind them, but it did not work with the grid exporters since overlapping elements are not supported there. The new frame element is recognized by the grid exporters and can be used to group elements together by nesting them inside a frame. Frames can be nested on an unlimited number of levels. Groups Groups represent a flexible way to organize data on a report.

We can have as many groups as we want on a report. The order of groups declared in a report design is important because groups contain each other. One group contains the following group and so on. When a larger group encounters a rupture, all subsequent groups are reinitialized. See the Jasper Sample report for an example on how to define groups. Fonts and Unicode Support Now you can create your reports in any language! New attributes in the element where introduced to allow the mapping between the Java fonts and the PDF fonts.

PDF uses special font settings and there was no way to make use of them in the previous version of JasperReports. With the introduction of those new attributes, the users can specify what PDF specific font should be used to display different character sets pdfFontName attribute , what is the type of the encoding pdfEncoding attribute and whether the font should be embedded in the PDF document or not isPdfEmbedded.

To simplify the use of the font settings, a new element was introduced:. Report fonts are report level font definitions that ca be used as default or base font settings in other font definitions throughout the entire report. Since the support for international characters is somehow tied to the iText library, you can find more details about how to create PDF documents in different languages and different character sets in the iText documentation.

Styles Report styles were introduced in order to group together a set of visual properties that would then be applied to report elements that reference the report style.

This new concept is an extension of the former report font concept which is now deprecated. Report elements that reference a report style definition could override the values of any visual property defined in the style. Report styles could also reference other report styles and the same inheritance and override mechanism applies to them too. Styles are useful when a whole range of elements need to share the same visual properties and any change made to that has to apply to all of them.

This can be achieved by changing the report style they all reference. Scriptlets All the data displayed on a report comes from the report parameters and from the report fields. This data can be processed using the report variables and their expressions. There are specific moments in time when variable processing occurs. Some variables are initialized according to their reset type when the report starts, or when a page or column break is encountered, or when a group changes.

Furthermore, variables are evaluated every time new data is fetched from the data source for every row. But only simple variable expressions cannot always implement complex functionality. This is where scriptlets intervene.

Scriptlets are sequences of Java code that are executed every time a report event occurs. Through scriptlets, users now have the possibility to affect the values stored by the report variables.

Since scriptlets work mainly with report variables, is important to have full control over the exact moment the scriptlet is executed. In order to make use of this functionality, users only have to create a scriptlet class by extending JRAbstractScriptlet class or JRDefaultScriptlet class. Those methods will be called by the report engine at the appropriate time, when filling the report.

It can be used in expressions throughout the report, to call custom methods on the scriptlet object, making the whole mechanism even more flexible. And that is all! See the ScriptletReport sample for more details. Subreports Subreports are an important feature for a report-generating tool. They allow the creation of more complex reports and simplify the design work.

Subreports are very useful when creating master-detail type of reports, or when the structure of a single report is not sufficient to describe the complexity of the desired output document. A subreport is in fact a normal report incorporated into another report.

One can overlap subreports or create subreports containing subreports themselves, up to any nesting level. Any report template can be used as a subreport when incorporated into another report, without anything inside it having to change.

Like other report elements, the subreport element has an expression that is evaluated at runtime in order to obtain the source of the JasperReport object to load. There are two ways to supply parameter values to a subreport. First, you can use the element which introducest the expression that will be evaluated to produce the specified parameters map. Subreports require a data source in order to generate their content, just like normal reports, behave in the same way, and expect to receive the same kind of input when they are being filled.

Values calculated by a subreport can be returned to the parent report. More specifically, after a subreport is filled, values of the subreport variables can be either copied or accumulated using an incrementer to variables of the caller report master variables. See the Subreport sample for details. Internationalization JasperReports allows associating a java.

In order to ease the internationalization of the reports there is a special syntax available inside report expressions that allows referencing String resources placed inside a java. ResourceBundle object associated with the report. For formatting messages in different languages, based on the report locale, there is a built-in method inside the JRCalculator associated with the report that offers functionality similar to the java.

MessageFormat class. This method is called msg and has 3 convenience signatures that allow using up to 3 message parameters in the messages.

In the generated output, the library now keeps information about the text run direction so that documents generated in languages that have right-to-left writing like Arabic and Hebrew could be rendered properly.

Check the I18nReport and UnicodeReport samples for details. Datasets Charts and crosstabs sometimes need to use data which the containing report does not iterate though directly at fill time. This would be the case with data sources that have fields which could themselves be data sources for subreports.

In order to eliminate the need to use subreports to render a chart or a crosstab that would be fed with the nested data, a new concept called a dataset was introduced.

A dataset is something between a data source and a subreport because it contains parameters, fields, variables and groups, but no layout information. Charts JasperReports now has built-in support for charts.

There is a new, ready-to-use chart component, although we already had images, text fields, subreports and other elements. This greatly simplifies the way charts are included inside reports, because previously the user had to completely rely on scriptlets in order to gather the chart data and render the chart using an image element in the report template.

Now with the new chart component, the user only has to make the desired visual settings and define the expressions that will help the engine build up the chart dataset in an incremental fashion during the iteration through the report data source. For all charts we can configure the following: border around all sides.
