Jasper is an open-source reporting and analytics tool.
A report in Jasper is a template that defines the layout and structure of the generated output, such as PDF or HTML.
You can create a report in Jasper by using the Jaspersoft Studio application or by designing it in JasperReports Server web interface.
Data sources in Jasper are connections to databases, XML files, or other data sources that provide the data for a report.
You can add a data source in Jasper by clicking on the "Add Data Source" button in the Data Sources view in Jaspersoft Studio or by configuring it in the Data Sources tab in JasperReports Server web interface.
You can publish a report in JasperReports Server by creating a new report unit and uploading the report file in the Repository Explorer.
A report unit in JasperReports Server is a container for a single report or a report group.
You can schedule a report to run in JasperReports Server by creating a new job and selecting the report and the desired schedule.
A job in JasperReports Server is a single unit of work that can run a report, perform an action, or execute a script.
This could be due to missing or incorrect data sources, design errors, or compatibility issues. Make sure to check the errors in the Problems view for more details.
This could be due to incorrect data source configuration, incompatible versions between the data source and JasperReports Server, or permission issues. Check the logs for more information.
You can troubleshoot data source connection errors in JasperReports Server by checking the logs for more details, verifying the data source configuration, and testing the connection manually.
This could be due to incorrect SQL queries, data source configuration, or data formatting. Try checking the query in Studio or modifying the data source configuration.
This could be due to the report using custom fonts that are not installed on your system. You can either install the required fonts or replace them with default fonts.
You can install custom fonts by copying the font files into the "fonts" folder in the JasperReports Server installation directory.
You can create a subreport in Jaspersoft Studio by using the Subreport element from the Palette and linking it to the desired report file.
This could be due to incorrect data source configuration in the subreport or the main report, or a missing link between the two. Check the data source settings and make sure to link the parameters correctly.
This could be due to incorrect or missing data source configuration, incorrect chart design, or compatibility issues. Check the chart configuration and data source settings for any errors.
You can use parameters in your report by first defining them in the report and then passing values when running the report. You can also create default values for parameters.
Bookmarks in Jasper are sections of a report that act as links to other sections of the same report, providing an interactive navigation experience.
You can use bookmarks in a report by creating bookmarks in the desired sections and using the Bookmark property in text elements to link to them.
This could be due to missing library files in your application or in the JasperReports Server installation. Make sure to include all required libraries in your application.
You can customize the look and feel of a report in JasperReports Server by using styles, themes, and properties in Jaspersoft Studio.
This could be due to incorrect page break settings, incorrect page numbering expression, or a bug in the report layout. Check the settings and adjust if needed.
You can export a report to different formats by using the Export button in the report viewer and selecting the desired format from the list.
Some of the available export formats in JasperReports Server include PDF, HTML, Excel, CSV, and RTF.
This could be due to a variety of reasons such as missing libraries, incompatible versions, incorrect credentials, or bugs in the report layout. Check the logs for more information.
You can schedule a report to be sent via email by creating a job and selecting "Email" as the output destination.
This could be due to incorrect email settings or server configuration, spam filters, or incorrect scheduling. Check the logs for more information and verify the settings.
You can set up permission settings for reports and folders in JasperReports Server by using the Permissions tab in the Repository Explorer and assigning roles to users or groups.
This could be due to insufficient permissions, a locked report, or a bug in the application. Make sure to have the correct permissions and check the logs for any error messages.
