How to fill jasper report table using collection of data in java

I have a probelm with my report. I do no use any Database. I come from Java Bans. Thats the Java Code My question is: How do set up the jrxml-File that i can see all parameters form the list file in the detail section? It's a datasource provided by jasper which you can initialize with a collection of your own java beans. Ok, the example is not that of what I'm looking for. I want to know, how to handle a java. List in a jrxml-Jasper Report.

Is there a way to put the attributes from that list into a Parameter or Field. That put out in the report: [1,2,3,4,5]. My Idea was to put the speed-field in the Detail-Section and jasper realize that the speed field is a list with 5 entries and put out: 1 2 3 4 5 Because the speed-field is in the Detail-Section with repeat values.

I ask me why I can create a field with the class java. List at the top and when I want to put this field in the report design area there is no java. After long search in the Web I belive you can not use a list directly. You have to put the list in a subreport as datasource expression. Is that right? If yes, how to put the list in the subreport. I have this in my Master. In my subreport. NoSuchMethodException: Unknown property 'speed' on class 'class java.

Because Jasper can not handle a list directliy I have made a little trick: For every list I make a new HashMap and put it to a main list. All other single attributes are putted to the list at the end. So now we have some HashMaps and in the last we have all single entrys.

Now I have all in one Report. Products Solutions Services Resources. Download Now. Hi, I have a probelm with my report. Joined: Jun 8 - am.

JasperCompileManager; import net. JasperFillManager; import net. JasperPrint; import net. JasperReport; import net. JasperDesign; import net. JRXlsExporter; import net.Datasources are structured data container. While generating the report, JasperReports engine obtains data from the datasources.

Data can be obtained from the databases, XML files, arrays of objects, and collection of objects. We saw in the chapter Filling Reportsthe fillReportXXX method expects to receive a data source of the report, which has to fill, in the form of net. JRDataSource object or a java. Connection when the report data is found in a relational database.

At the report filling time, this method is called on the data source object by the reporting engine when iterating through the data. The only way to retrieve data from the data source is by using the report fields.

There are several default implementations of the JRDataSource interface, depending on the way, the records in the data source are acquired. ResultSet object. This is the most commonly used data source implementations when report data are extracted from a relational database. If a java. Connection is passed to the engine instead, it executes first the related query and stores the returned java.

Each object inside the array or the collection will be seen as one record in this type of data source. The mapping between a particular JavaBean property and the corresponding report field is made by naming conventions. The name of the report field must be the same as the name of the JavaBean property as specified by the JavaBeans specifications. Map objects. Each Map object in the wrapped array or collection is considered a virtual record in the data source, and the value of each report field is extracted from the map using the report field named as the key.

In many client-side applications, data is displayed in tabular format. A common requirement in many applications is to allow the user to print this tabular format as a report. This class wraps a javax. TableModel object. Columns in the wrapped TableModel object can be accessed either by their names or by their 0-based indexes.

Records in the XML data source are represented by node elements selected through the XPath expression. XPath is a language used to navigate through an XML document's attributes and elements.A collection of JavaBeans data adapter allows you to use JavaBeans as data for a report.

In this context, a JavaBean is a Java class that exposes its attributes with a series of get methods, with the following syntax:. The collection of JavaBeans data adapter uses an external class named Factory to produce some objects the JavaBeans that constitute the data to pass to the report.

To use a collection of JavaBeans as a data adapter in Jaspersoft Studioyou must create an instance of the Factory class and provide a static method to instantiate different JavaBeans and to return them as a collection java. Collection or an array Object[]. The following example shows how you might create write an instance of the Factory class. Suppose that you have an collection of JavaBeans, where the data is represented by a set of objects of type PersonBean.

To use this collection of beans, you need to create an instance of the Factory class. Your class, named TestFactorymust contain the actual data that is used by the report.

In this case, it will be something similar to this:. A data adapter based on this class would represent five JavaBeans of PersonBean type. Once you have created your Factory class instance, you can create a data adapter that uses your collection of JavaBeans.

One peculiarity of a collection of JavaBeans data adapter is that the fields are exposed through get methods. This means that if the JavaBean has a getXyz method, xyz becomes the name of a record field the JavaBean represents the record. In this example, the PersonBean object shows two fields: name and age.

Register them in the fields list as a String and an Integerrespectively. Create a new empty report and add the two fields by right-clicking the Fields node in the outline view and selecting Add field. The field names and the types of the fields are: name java.

String and age java. Drag the fields into the Detail band and run the report. Make sure the active connection is the TestFactoryAdapter. To refer to an attribute of an attribute, use periods as a separator. For example, to access the street attribute of an Address class contained in the PersonBeanthe syntax would be address. If you selected Use field description when you specified the properties of your data adapter, the mapping between JavaBean attribute and field value uses the field description instead of the field name.

Jaspersoft Studio provides a visual tool to map JavaBean attributes to report fields. To use it, open the query window, go to the tab JavaBean Data Sourceinsert the full class name of the bean you want to explore, and click Read attributes. The tab displays the attributes of the specified bean class. Products Solutions Services Resources.

Vector ; collection. To create the connection local to a project, clickenter a name and location for the data adapter in the DataAdapter File dialog box, and then click Next.

To create a connection to handle JavaBeans, select Collection of JavaBeans in the list of data adapter types. Enter the name of your Java class in the Factory class. For the example above, you would need to specify the class name for TestFactory. Enter the name of the static method in your Factory class.

In this article, we will talk about JasperReports library and also discuss how to use it. It has the ability to use data coming from any type of data source and can produce formatted reports.

JasperReports is an open source Java based reporting tool which can write outputs to a wide range of targets e. It is widely used in Java-based applications, which includes Java EE or web applications, in order to generate dynamic content. Instructions to generate the reports are stored in an XML or a. In the Jasper Reports library, there are different classes for different purpose. This XML file contains the tag as its root element.

This root element in turn contains multiple sub-elements all of which are optional. JasperReport framework has the ability to handle different types of data sources.

In this document we will see how to generate a basic report, by just passing a collection of Java data object or a POJO. Here we will use Java beans. The final report will show Name, City, State and Country of a list of people. The report template is designed and created in following two steps —.

In order to preview the report template file, we need to execute the utility - net. This utility helps in previewing the report design without having to compile it or fill it. This is a standalone Java application and hence can be executed using the java command or using an ant script. Before executing this application, make sure to have the following libraries in the system classpath.

Here we see that only the report expressions used to fetch the actual data is shown out since at this stage we don't have access to the real time data. The interface net. JRCompiler which is part of the jasperreport library plays a vital role in compilation of this report template file.

Implementation of this interface can be written in Java, Groovy, JavaScript or any other scripting language. Let us write a Java program as under —.

JRException; import net. The default language is set to groovy in this file. Once the compilation is over successfully, we can see a jasper file is generated in the same location where the JRXML file is saved.

We can use this jasper file to preview our report as under —. It should be noted that here we are using the jasper file as a parameter while earlier we were using the JRXML file as a parameter. Once executed, we can see the same report design as shown in Figure 3. The goal of any reporting tool is to produce high standard documents. The report filling process helps the reporting tool to achieve this by manipulating the datasets.
