Om dette verktøyet

The JRXML Validator Online analyzes JasperReports JRXML templates for both structural integrity and domain-specific correctness. It detects syntax errors, missing or duplicate elements, and misreferences that commonly cause runtime failures.
The tool performs XML well-formedness checks, validates against the standard JRXML schema, and runs semantic validations on fields, parameters, datasets, variables, and subreports. While it does not execute reports, it provides precise line and column information for each issue to accelerate fixes.
Core feedback includes error codes, severity levels, and actionable suggestions to resolve problems in a minimal number of edits. The system is designed for developers, BI engineers, testers, and CI pipelines who need reliable JRXML templates before deployment.
This specialization reduces debugging time, improves template stability, and supports iterative design reviews with exportable validation reports.

Hvordan bruke

Provide inputs: paste the JRXML source text into the input area.
Choose validation mode: enable semantic checks if you want deeper consistency validation.
Run validation: initiate the analysis to produce errors, warnings, and suggestions.
Review outputs: examine codes, locations, and fix recommendations to update the JRXML.
Iterate: re-run validation after corrections until no critical issues remain.

Frequently Asked Questions

Finn raske svar

What is JRXML and what does validation cover?

JRXML is the JasperReports XML design format. Validation covers XML well-formedness, schema conformance against the JRXML schema, and domain-specific references for fields, parameters, datasets, and subreports without executing the report.

Can the tool validate expressions and references?

Yes. Semantic checks validate expression syntax, variable scopes, and cross-references among fields, parameters, and data sources to catch subtle design issues before runtime.

What outputs are produced?

The tool returns a structured list of errors and warnings with location data (line/column), codes, severities, and recommended fixes. It does not render or execute reports.

How can I use the results in workflows?

Results can be copied into issue trackers, exported as JSON or text summaries, and integrated into CI pipelines to block merges until JRXML templates pass validation.
