NoSuchMethodError During PDF Export with PrimeFaces 14.0.3

[buddhika75]

I am encountering an issue while exporting a DataTable to PDF using PrimeFaces 14.0.3. The following error occurs:

java.lang.NoSuchMethodError: 'com.lowagie.text.pdf.PdfPCell com.lowagie.text.pdf.PdfPTable.addCell(com.lowagie.text.pdf.PdfPCell)'

Environment Details:

• PrimeFaces Version: 14.0.3 (also tried 14.0.6)
• OpenPDF Version: 1.4.1 (also tried 1.4.2)
• JSF Version: 2.3
• Java Version: 11
• Application Server: Payara 5

Relevant pom.xml Dependencies:

<dependency>
    <groupId>com.github.librepdf</groupId>
    <artifactId>openpdf</artifactId>
    <version>1.4.1</version>
</dependency>

<dependency>
    <groupId>org.primefaces</groupId>
    <artifactId>primefaces</artifactId>
    <version>14.0.3</version>
</dependency>

Steps to Reproduce:

1. Implement a DataTable in a JSF page.
2. Add a p:commandButton with a nested p:dataExporter for PDF export.
3. Deploy the application and attempt to export the DataTable as a PDF.

Observed Behavior:

Upon initiating the PDF export, the application throws the NoSuchMethodError mentioned above.

Troubleshooting Steps Taken:

• Verified that the OpenPDF and PrimeFaces versions are compatible as per the PrimeFaces documentation.
• Cleaned and rebuilt the project to ensure all dependencies are correctly applied.
• Reviewed the pom.xml for potential conflicts with other dependencies.

Request for Assistance:

I am seeking guidance on resolving this NoSuchMethodError. Specifically:

• Is there a known compatibility issue between PrimeFaces 14.0.3 and OpenPDF 1.4.1 for PDF exports?
• Could other dependencies in my project be interfering with the PDF generation process?
• Are there additional configurations required in PrimeFaces or OpenPDF to handle PDF exports correctly?

Any insights or recommendations to address this issue would be greatly appreciated.
