Problema

Quando si utilizza il codice API contenuto nella Developer Guide per Reader Extensions 7.2.2 (developer_guide.pdf ) per fornire ulteriori autorizzazioni ai documenti PDF, si riceve la seguente eccezione:

Soluzione

Utilizza una o entrambe le soluzioni, a seconda delle necessità

DataManager e PDFMM non sono accessibili da remoto. Pertanto, devi eseguire il tuo codice cliente sullo stesso server di ARES. Scrivi la tua EJB sul server ARES con connessioni remote, e poi chiama questo codice dalla macchina remota.

Assicurati che il tipo di transazione EJB sia Bean e non Container::

nel file ejb-jar.xml, cambia il tipo di transazione da Container a Bean:

 <session > <description><![CDATA[The typical Session Bean this time as a web-service.]]></description> <display-name>Adobe Extension Web Service for JBoss.Net</display-name> <ejb-name>AdobeExtensionService</ejb-name> <home>com.twowin.services.AdobeExtensionServiceHome</home> <remote>com.twowin.services.AdobeExtensionService</remote> <ejb-class>com.twowin.services.AdobeExtensionServiceBean</ejb-class> <session-type>Stateless</session-type> <transaction-type>Bean</transaction-type>

Poi, ricompila il file .ear e distribuiscilo sul tuo application server.

Informazioni aggiuntive

Questa eccezione si verifica quando si tenta di avviare una transazione e gli oggetti DataManager e PDFMM restituiti dal file JNDI namingcontext.lookup() sono nulli.

Fornisci permessi aggiuntivi ai documenti PDF utilizzando l'interfaccia web di Adobe Reader Extensions.
