Thanks to a community that is hundreds-of-thousands strong Jaspersoft’s commercial and open source software has been downloaded millions of times and is used to create the Intelligence Inside apps and business processes.
Features of Jaspersoft Report: JasperReports is an open source reporting library that can be embedded into any Java application. Features include:
- Scriptlets may accompany the report definition, which the report definition can invoke at any point to perform additional processing. The scriptlet is built using Java and has many hooks that can be invoked before or after stages of the report generation, such as Report, Page, Column or Group.
- Sub-reports
For users with more sophisticated report management requirements, reports designed for JasperReports can be easily imported into the JasperServer – the interactive report server.
Q3 : What is iReport?
A : Basically, iReport is the report designer and JasperReport is the reporting engine.
A : To change the version of Java used by iReport, the following setting has to be added or updated.
<irepor-install-directory>/fonf/ireportpro.conf
or <ireport-install-directory>/ireport/etc/ireportpro.conf.
The use of the command line would depend on the installation made
A : In iReport JAR is made on building the project containing the Scriptlet.
A : The documentation of iReport should be carried out by the user and not with some readymade packages that are mostly not fruitful for the purpose.
A :
- Pixel Perfect Reporting: Highly formatted reports containing interactive charts, images, sub-reports, expressions, and more. Reports from any data source including JDBC, XML, CSV, Hibernate, POJO. Reports published in PDF, XML, HTML, CSV, DOC, ODT.
- Ad Hoc Reporting: Web-based, drag-and-drop report designer. Crosstabs, tables, and chart-based reports. Semantic layer against relational or non-relational data sources.
- Advanced analytic functions: Ability to analyze data across multiple attributes and time periods. Multidimensional Expression Language (MDX) support lets users run complex analytic queries. Addition of calculations at runtime or within the relational OLAP model.
- Interactive user interface: Intuitive web-based interface lets users drill down, drill across, drill up, filter, pivot, sort, and chart. Ability to use MS Excel as a front-end client to your OLAP environment. Granular security access down to the cell and column level.
- Performance and scalability: Sophisticated caching of data and dimensions reduce query latency. Relational database storage architecture. Aggregate-aware architecture simplifies setup and improves user response times.
- Graphical design environment: Business-oriented models for early design collaboration. Drag-and-drop process designer. Activity monitoring console tracks job execution and performance.
- Connectors: Native connectivity to ERP and CRM applications such as Salesforce.com, SAP, and SugarCRM. Support for mainframe, transactional, and analytic databases. Connectivity to Hive for Hadoop environments.
- ELT support: ELT connector support for Oracle, DB2, Postgres, IBM/Netezza, EMC/Greenplum, Teradata, and SAP/Sybase IQ. Merge, filter and rollback functions. ELT template jobs for re-use.
Q9 : What Are The System Requirements For Ireport?
A : Some of the system requirements for the iReport are Sun JDK 1.4 or greater, Ant, JasperReports 0.4.6, Sax 2.0 XML Parser, a host of Jakarta commons components and Acrobat Reader.
Q10 : Who Are The Customers Of Jaspersoft?
A : The Jaspersoft’s customers come mainly from the ISV sector. But basically, the companies that create their own application. So a very wide range of organizations is there, even from the public sector. Creating Dashboards and Reports is basically what customers do with Jaspersoft software. Those are static reports or interactive HTML5 charts. The reports and dashboards can be accessed from any mobile device, which provides a neat overview. You also have the option to get a deep analytical view.
Q11 : What Languages And Codes Are Supported By Ireport?
A : iReport supports Unicode and much non-Latin language (Russian, Chinese, Korean). It also supports different fonts.
Q12 : What Are The Databases And Data Source That Is Supported By Ireport?
A : iReport supports all JDBC compliant databases and also all kinds of JRData Source. It also supports subreports as well as templates.
Q13 : What Is The Link Where Information About Ireport Would Be Available?
A : It is the iReport homepage where user can get all the information about the application and its uses.
Q14 : What Are Two Main Features Of Ireport?
A : Two main features of iReport are it supports 98% of JasperReport tags and it has a built-in editor with syntax highlighting for write expression.
Q15 : Is It Necessary for Installing Additional Files After Installing The Standard Version Of Ireport?
A : Setting up the JAVA_HOME environmental variable with path as C:\Program Files\jasperserver-pro-3.7\java\jre can address the problem.
Q16 : What Is The Process Of Documentation Of Ireport In Java?
A : The documentation of iReport should be carried out by the user and not with some readymade packages that are mostly not fruitful for the purpose.
Q17: What Is The Specific Necessity Of The Class Containing User Defined Function?
A : The class containing the user-defined functions needs to be extended by the JRDefaultScriptlet.
Q18 : What Is Achieved By Scriptlets?
A : Scriptlets are the bridges that get the Java Code in iReport. iReport.scriptlet is a Java class that extends JRDefaultScriptlet where one can write user-defined functions that can later be accessed easily in the report.
Q19 : What Are The Steps For Identifying The Default Java Version Used For Generating Ireport?
A : When iReport designer is using the default Java installation for the environment, opening a command line and executing the following command would help – java-version/
Q20 : How To Solve The Problem Of Running Ireport When It Generates Java Error?
A : The config file is available in the etc folder where the jdkhome has been set. The path that is to be given there is the jdk path and not jre path. Installation of jdk is essential for the purpose.
Q21 : What Is Basically Ireport?
A : Basically is a visual designer for the JasperReports.
Q22 : What Is The Parameter For Using User Defined Function In Ireport?
A : The parameter in iReport for using the user-defined function is $P{REPORT SCRIPTLET} which is a predefined parameter for the user.
Q23 : What Are Other User Defined Functions Used In Ireport?
A : Other user-defined functions in iReport are $P{REPORT SCRIPTLET}.userDefinedfun($F{field}). These functions give fluidity to Java from the Jasper to Java code.
Q24 : Is It Good Using Packages For Ireport Documentation?
A : If at all; only the quality documentation package should be used and the iReport should not have any circular references that would create unnecessary problems.
Q25 : Are There Any Facilities For Having Backup In Ireport?
A : Yes. The user can backup data and information with iReport.
