Run time error java.lang.ClassNotFoundException not found by org.xhtmlrenderer.flying.saucer.pdf.itext5 [613]

 I'm working on the implementation of html to pdf generation, where i have done below pom config,

<dependency>
<groupId>org.xhtmlrenderer</groupId>
<artifactId>flying-saucer-core</artifactId>
<version>9.1.20</version>
</dependency>
<dependency>
<groupId>org.xhtmlrenderer</groupId>
<artifactId>flying-saucer-pdf-openpdf</artifactId>

<artifactId>flying-saucer-pdf-osgi</artifactId>
<version>9.1.2</version>

</dependency>
<dependency>
<groupId>org.xhtmlrenderer</groupId>
<artifactId>flying-saucer-pdf</artifactId>
<version>9.1.20</version>
</dependency>

and in plugin I have added this line 

<plugin>
    <groupId>biz.aQute.bnd</groupId>
    <artifactId>bnd-maven-plugin</artifactId>
    <executions>
        <execution>

            <goals>
                <goal>bnd-process</goal>
            </goals>
            <configuration>
                <bnd><![CDATA[
Export-Package:

  com.lowagie;version="2.1.7",\
  org.xhtmlrenderer;version="9.1.20",\
  org.xhtmlrenderer.pdf.ITextRenderer.*;version="9.1.20",\

The build is fine and the bundle is active. 

In my code I am able to get the apis of ITextRenderer. 

org.xhtmlrenderer.pdf.ITextRenderer iTextRenderer = new org.xhtmlrenderer.pdf.ITextRenderer();

But on Runtime I am getting this exception in error.log.

java.lang.ClassNotFoundException: org.xhtmlrenderer.pdf.ITextRenderer

could you please suggest anyone ?

Hi @vkarthick,

Did you try following things?

• Restarting AEM instance
• Using different version of the dependency
• Check the scope of the dependency. It has to be available at runtime as well. Try with scope "provided".
• Checking any other error in stack trace.

Hello @salamswapnil ,

• Restarting AEM instance - tried but same result.
• Using different version of the dependency -tried but causing more issue. same version works fine in on prem AEM.
• Check the scope of the dependency. It has to be available at runtime as well. Try with scope "provided". - its already added
• Checking any other error in stack trace. - not finding anything useful.

@vkarthick,

Try embedding these 3rd party jar file along with the bundle. You can follow this article on how to embed the 3rd party jars in maven build.

Hello Sudeer,

its already embedded in all/pom.xml.

And its working fine in on prem AEM and java 1.8, the problem arose in AEMaaCS. not sure is it becasue of java 11??

@salamswapnil @Sudheer_Sundalam , 

The resources folder not able to access from dependency.

i'm gettting below error,

WARNING: Flying Saucer: No configuration files found in classpath using URL: resources/conf/xhtmlrenderer.conf, resorting to hard-coded fallback properties.

org.xhtmlrenderer.exception WARNING:: Can't load default CSS from /resources/css/XhtmlNamespaceHandler.css.This file must be on your CLASSPATH.

if i keep this resource folder under core module it is working fine.

does anyone face this issue???
