The code of the conversion is standard:

    File inputFile=new File("document.doc");
    File outputFile=new File("document.pdf");
    OpenOfficeConnection connection = new SocketOpenOfficeConnection(8100);
    connection.connect();

    // convert
    DocumentConverter converter = new OpenOfficeDocumentConverter(connection);
    converter.convert(inputFile, outputFile);

    // close the connection
    connection.disconnect();

Into the terminal :

soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard

I don't understand why i've the exception :(

PS. into the war section i'm adding a folder "lib" with the library (jodconverter2.2.2.jar)

Answer 1

NoClassDefFoundError exception is thrown when the class is not found in classpath. So if you are trying to access this class in ejb it has to be available to it.

If you added lib folder in your .war file, the ejb .jar can not see lib folder placed under .war file.

You need to create lib folder in your .ear file and in application.xml file specify that library directory is for both: your web application .war and ejb .jar.

<?xml version="1.0" encoding="UTF-8"?>
<application xmlns="http://java.sun.com/xml/ns/javaee"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/application_6.xsd"
             version="6">
    <display-name>yourapp</display-name>
    <module>
        <ejb>yourapp-ejb.jar</ejb>
    </module>
    <module>
        <web>
            <web-uri>yourapp.war</web-uri>
            <context-root>/</context-root>
        </web>
    </module>
    <library-directory>lib</library-directory>
</application>

This line <library-directory>lib</library-directory> specifies that your lib directory is in .ear archive. Also you need to remove lib folder from your .war file.
