JODConverter 、 NoClassDefFoundError に問題があります。私は netbeans 7.1.2 、jdk 1.7 、jodconverter2.2.2.jar および openoffice 3.3.0 を使用しています。私は Java エンタープライズ アプリケーションを構築しており、ejb セクションで i 「jodconverter2.2.2.jar ライブラリを追加しています (ejb プロジェクトを右クリックし、プロパティ、ライブラリは jar/フォルダを追加します)。しかし、アプリケーションを実行して .doc ファイルを変換したい場合:

変換のコードは標準です。

    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();

ターミナルに:

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

例外がある理由がわかりません:(

PS。warセクションに、ライブラリ（jodconverter2.2.2.jar）を含むフォルダー「lib」を追加しています

クラスパスにクラスが見つからない場合、NoClassDefFoundError 例外がスローされます。したがって、ejb でこのクラスにアクセスしようとしている場合は、アクセスできる必要があります。

.war ファイルに lib フォルダーを追加した場合、ejb .jar は .war ファイルの下に配置された lib フォルダーを認識できません。

.ear ファイルに lib フォルダーを作成し、application.xml ファイルで、ライブラリー・ディレクトリーが Web アプリケーションの .war と ejb .jar の両方であることを指定する必要があります。

<?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>

この行<library-directory>lib</library-directory>は、lib ディレクトリが .ear アーカイブにあることを指定します。また、.war ファイルから lib フォルダーを削除する必要があります。
