Section section = document.addSection();

Paragraph para1 = section.addParagraph();

para1.appendText("Proforma Invioce");

There error is caused at this line "Paragraph para1 = section.addParagraph();"

Code is written in spring boot . In local its working fine.

Why am I getting this error when I deploy the code to the server ?

Answer 1

Tested below with e-iceblue:spire.pdf.free:4.4.1 and e-iceblue:spire.pdf.free:5.1.0

Issues we had

1. Caused by: java.lang.NoClassDefFoundError: Could not initialize class com.spire.doc.packages...
2. com.spire.ms.System.Exception: No 'Arial' font found!

Although we did not figure out what the core reason is we figured it out how to get things working.

change	impact
Used JDK instead of JRE	fixed classloading issues (your issue outlined above did not appear)
Used debian instead of alpine (as base)	unknown
Installed msttcorefonts	no missing Arial issue

Knowing that this is not a lightweCaused by: java.lang.NoClassDefFoundError: Could not initialize class com.spire.doc.packages... com.spire.ms.System.Exception: No 'Arial' font found!ight docker image anymore, but it works we used the following Dockerfile.

FROM openjdk:11-jdk
RUN echo "update packages" && apt update && \
  echo "install ms fonts" && \
    sed -i'.bak' 's/$/ contrib/' /etc/apt/sources.list && \
    apt update && \
    apt install -y ttf-mscorefonts-installer fontconfig && \
    fc-cache -f -v

// add other application files

I hope it helps, good luck
