JasperReports Tutorial for Beginners - Learn JasperReports in simple and easy steps PDF Version JasperReports is an open source java reporting engine. JasperReports i. About the Tutorial. JasperReports is an open source java reporting engine. JasperReports is a Java class library, and it is meant for those Java.

Here I connect with Oracle database. There are specific moments in time when variable processing occurs. But only simple variable expressions cannot always implement complex functionality. Next, adjust the height of Column Header so that it is equal to the height of newly-made Rectangle. For variables that perform calculation we can specify the level at which they are reinitialized. MessageFormat class. Report Programming.

PreparedStatement parameters using the following syntax:. Sometimes is useful to use parameters to dynamically modify portions of the SQL query or to pass the entire SQL query as a parameter to the report filling routines. In such a case, the syntax differs a little, like in the following example:.

ResultSet object. It allows the use of any relational database through JDBC. When using a JDBC data source, you could pass a java.

Connection object to the report filling operations and specify the query in the report definition itself see the element in the XML file or could create a new instance of the JRResultSetDataSource by supplying the java. ResultSet object directly. With other types of data sources, things should not be different and all you have to do is to implement the JRDataSource interface, or use one of the implemetations that are shipped with the JasperReports library to wrap in-memory collections or arrays of JavaBeans, CSV or XML files, etc.

Report fields represent the only way to map data from the data source into the report generating routines. When the data source of the report is a java.

JasperReports Tutorial

ResultSet, all fields must map to corresponding columns in the java. That is, they must have the same name as the columns they map and a compatible type. If we want to generate a report using data retrieved from the table Employees, which has the following structure:.

If we declare a field that does not have a corresponding column in the java. ResultSet, an exception will be thrown at runtime. Columns present in the java. ResultSet object that do not have corresponding fields in the report design do not affect the report filling operations, but they also won't be accessible. Expressions are a powerful feature of JasperReports.

They can be used for declaring report variables that perform various calculations, for data grouping on the report, to specify report text fields content or to further customize the appearance of objects on the report. Basically, all report expressions are Java expressions that can reference report fields and report variables.

For example, if we want to display in a text field, on the report, the concatenated values of two fields, we can define an expression like this one:. There is an equivalent syntax for using parameters in expressions. A Report variable is a special objects build on top of an expression.

Variables can be used to simplify the report design by declaring only once an expression that is heavily used throughout the report design or to perform various calculations on the corresponding expressions. In its expression, a variable can reference other report variables, but only if those referenced variables were previously defined in the report design.

So the order in which the variables are declared in a report design is important. As mentioned, variables can perform built-in types of calculations on their corresponding expression values like: For variables that perform calculation we can specify the level at which they are reinitialized.

The default level is Report and it means that the variable is initialized only once at the beginning of the report and that it performs the specified calculation until the end of the report is reached. But we can choose a lower level of reset for our variables in order to perform calculation at page, column or group level.

For example, if we want to calculate the total quantity on each page, we should declare our variable like this:. When building a report design we need to define the content and the layout of its sections. The entire structure of the report design is based on the following sections:.

Sections are portions of the report that have a specified height and width and can contain report objects like lines, rectangles, images or text fields.

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.

It contains only a line object and a static text:. Sometimes a group of elements have to share a common background or have a common border around them. 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 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. When declaring a report group, along with its corresponding data grouping expression, we have to declare the two sections: See the Jasper Sample report for an example on how to define groups. 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.

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.

On the report, we group it to get a result as the following illustration:. Select Acc. Here I connect with Oracle database. JDBC Url: Error emerges when you do not declare the classpath of Database Library Driver.

Outline View is very important. We often have to use it while designing a report. A blank report page is created. You can delete unnecessary parts of content by right-click on it and click Delete. We can recreate them if necessary. JDBC Url: Error emerges when you do not declare the classpath of Database Library Driver.
