Question

I am writing a JasperReports program where I want the query to be externalized to properties file.

I am injecting the query as string in my Java program.

In the jrxml file I have the following statements:

<parameter name="mySqlQuery" class="java.lang.String"/>

<queryString> 
    <![CDATA[$P{mySqlQuery}]]>
</queryString>

The Java program has the following:

hashmap.put("mySqlQuery", this.mySqlQuery);

JasperReport jasperReportMyClass = JasperCompileManager.compileReport(this.reportMyClass);
JasperPrint jasperPrintMyClass = JasperFillManager.fillReport(jasperReportMyClass, hashmap, con);
jprintList.add(jasperPrintMyClass);

Which I am then exporting to excel.

If I am hardcoding the same query directly in the JRXML queryString tags, it works fine.

Thanks for reading!

Answer 1

Is it possible to use parameter in queryString tag in jrxml file in jasper report?

Yes, it is possible.

Try to use $P!{mySqlQuery} expression instead of $P{mySqlQuery} in your jrxml file.
