About This Tool

Purpose-built JRXML generator that converts structured definitions into a valid JasperReports XML template. It encodes fields, parameters, and report structure into a cohesive JRXML scaffold. The system abstracts data source selection (SQL, CSV, JSON, XML) and maps each field to a JRXML entry, while governing layout sections such as title, page, column headers, detail, and summary. Core logic enforces XML validity, unique field names, and consistent parameter usage. Advanced capabilities include optional subreports, variable declarations, and conditional styles driven by locale or parameter values. The generated template is suitable for iterative design in JasperReports Studio and deployment in reporting pipelines. Errors such as missing inputs, duplicate field names, or unsupported data sources are surfaced as diagnostic information without UI messaging. The tool targets standard JRXML versions and common page sizes (A4, Letter), with locale-aware formatting for dates and numbers. It does not execute queries or render data; it only assembles a template skeleton that can be compiled at build or run time.

How to Use

Provide inputs: data_source_type, data_source_config, fields, and parameters.
Choose layout: pageSize, margins, orientation, and column settings.
Run generation: produce a JRXML skeleton with mapped fields and parameters.
Retrieve outputs: obtain JRXML string or downloadable file for JasperReports Studio.
Validate and refine: adjust inputs or styles and regenerate as needed.

Frequently Asked Questions

Find Quick Answers

What data sources are supported?

SQL, CSV, JSON, and XML data sources are supported. For SQL, a valid queryString or dataSourceConfig is required; for file-based sources, fields must be defined explicitly. The generator does not execute queries; it only produces a JRXML template configured for the given source.

Can I extend the template after generation?

Yes. You can edit the resulting JRXML directly or re-run with updated input definitions. The tool outputs a standards-compliant JRXML template, but it does not compile or render reports; integration with JasperReports Studio or a runtime environment is required.

What version compatibility is assumed?

The generator targets JRXML 6.x compatibility and common JasperReports engine versions. If you require legacy or non-standard features, specify constraints and expect adaptations in the output or an additional post-generation step.
