How we can change the default file creation path

[shinurag]

Could you please let me know how to change the temporary file creation location to a different folder path for the following line of execution?

jPrintFile = JasperFillManager.fillReport(jReport, params, jrbcds);
// jReport : JasperReport
// params: HashMap<String, Object> params = new HashMap<>();
// jrbcds: JRBeanCollectionDataSource

[teodord]

Which temporary files are we talking about and why would their location be important to worth changing?

Thank you,
Teodor

I developed a JAR file for generating PDF files, but the process terminated at
jPrintFile = JasperFillManager.fillReport(jReport, params, jrbcds); While this JAR file functions correctly in the lower environment, it only works intermittently in production, where it often fails. To address this, we plan to change the file creation folder to determine if it resolves the issue.

You can change the Java temporary files folder by passing an argument like -Djava.io.tmpdir=/path/to/temp/folder when starting the Java process. Note that this will apply to other temporary files created by the Java process.
