# Exception in thread "Launcher: SwCreatePDF" java.lang.NoClassDefFoundError: -CLASS NAME-

PDF Converter engine is written in Java and its JAR files must be loaded in the Notes client JVM.\
The JVM **loads new JARs only on startup** so a restart is required if JVM is already running.

To resolve the issue locate the **ext** folder in your Notes installation (for example C:\Program Files\IBM\Notes\jvm\lib\ext).

If you find any of the JARs listed below in that folder, delete them:

* bcpkix-jdk13-151.jar
* bcprov-jdk13-151.jar
* commons-codec-1.4.jar
* commons-httpclient-3.0.jar
* commons-io-1.4.jar
* commons-logging-1.1.1.jar
* flying-saucer-sw\.jar
* htmlcleaner2\_1.jar
* iText-2.1.7-sw\.jar
* jai\_codec.jar
* jai\_core.jar
* jodconverter-3.0.4.jar
* juh-3.2.1.jar
* jurt-3.2.1.jar
* ridl-3.2.1.jar
* slf4j-api-1.7.7.jar
* swlmbcs.jar
* swpdfc-2.0.0.jar
* sw-unoil-3.2.1.jar
* swUtilities.jar
* xstream-1.3.1.jar
* zip4j\_1.3.2.jar

Now install the latest version of Seascape and restart your Notes client afterwards.

If restarting does not help it is recommended to do a **complete SWING Seascape removal** and start the conversion again. This will force SWING Seascape to set up all required resources again. Removal guidelines are available here:
