The following code example determines whether the document
is a PDF document and, if so, the earliest Acrobat version able
to read it. (See Retrieving PDF Document Properties.)
/*
* This Java Quick Start uses the EJB mode and contains the following JAR files
* in the class path:
* 1. adobe-pdfutility-client.jar
* 2. adobe-livecycle-client.jar
* 3. adobe-usermanager-client.jar
* 4. adobe-utilities.jar
* 5. jbossall-client.jar (use a different JAR file if the LiveCycle Server is not deployed
* on JBoss)
* 6. jacorb.jar (use a different JAR file if the LiveCycle Server is not deployed on JBoss)
* 7. jnp-client.jar (use a different JAR file if the LiveCycle Server is not deployed on JBoss)
*
* The JBoss files must be kept in the jboss\client folder. You can copy the client folder to
* your local development environment and then include the 3 JBoss JAR files in your class path
*
* These JAR files are located in the following path:
* <install directory>/sdk/client-libs/common
*
* The adobe-utilities.jar file is located in the following path:
* <install directory>/sdk/client-libs/jboss
*
* The jbossall-client.jar file is located in the following path:
* <install directory>/jboss/client
*
* If you want to invoke a remote LiveCycle Server instance and there is a
* firewall between the client application and the server, then it is
* recommended that you use the SOAP mode. When using the SOAP mode,
* you have to include additional JAR files located in the following
* path
* <install directory>/sdk/client-libs/thirdparty
*
* For information about the SOAP
* mode and the additional JAR files that need to be included,
* see "Setting connection properties" in Programming
* with LiveCycle
*
* For complete details about the location of the LiveCycle JAR files,
* see "Including LiveCycle Java library files" in Programming
* with LiveCycle
