Problem accessing Reader Extensions

[Former Community Member]

Hi,<br /><br />I 've installed Adobe Lifecycle Toolbox 7 for windows (http://www.adobe.com/devnet/livecycle/toolbox/index.html) on a Windows XP for development-purpose. But untill now I was unable to communicate with the Server.<br /><br />The servers runs fine (all admin-pages are working) and by playing with some parameters (portnbrs, urls) I know I'm connecting to it.<br /><br />We installed the program with all default features (all default options) and tried to run sample-code from WSAD (sample-code bellow). We recieve a class-cast exception when trying retrieve the ConnectionFactory.<br /><br />Following adobe-libraries have been included in our classpath as mentioned in the documentation.<br /> - PDFManipulationAPI.jar<br /> - datamanager-client.jar<br /> - jboss-common-client. jar<br /> - jnp-client.jar<br /> - gnu-regexp.jar<br /> - DocumentServiceLibrary.jar<br /><br />I need to enable on a pdf the annotation-functionality.<br /><br />Thx for your help in advance..<br /><br /><u>Sample Code:</u><br /><b><br />package com.kbc.x37.test;<br /><br />import java.io.File;<br />import java.io.FileInputStream;<br />import java.io.InputStream;<br />import java.util.Hashtable;<br />import java.util.Properties;<br /><br />import javax.naming.Context;<br />import javax.naming.InitialContext;<br />import javax.rmi.PortableRemoteObject;<br /><br />import com.adobe.document.pdf.Credential;<br />import com.adobe.document.pdf.CredentialLoginFailure;<br />import com.adobe.document.pdf.FORM_ADD;<br />import com.adobe.document.pdf.FORM_DELETE;<br />import com.adobe.document.pdf.FORM_EXPORT;<br />import com.adobe.document.pdf.FORM_FILL_IN;<br />import com.adobe.document.pdf.FORM_IMPORT;<br />import com.adobe.document.pdf.FORM_SPAWN_TEMPLATE;<br />import com.adobe.document.pdf.FORM_SUBMIT_STAND_ALONE;<br />import com.adobe.document.pdf.NotAllowedByCredential;<br />import com.adobe.document.pdf.PDFDocument;<br />import com.adobe.document.pdf.PDFFactory;<br />import com.adobe.document.pdf.PDFFactoryHelper;<br />import com.adobe.service.ConnectionFactory;<br />import com.adobe.service.DataManager;<br />import com.adobe.service.DataManagerHelper;<br />import com.adobe.service.FileDataBuffer;<br /><br />public class TestReaderExt {<br /><br /> public static void main(String[] args) throws Exception {<br /><br /> // Declare a ConnectionFactory object<br /> ConnectionFactory pdfConnectionFactory = null;<br /><br /> <br /> Hashtable hashtable = new Hashtable();<br /> hashtable.put("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");<br /> hashtable.put("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");<br /> hashtable.put("java.naming.provider.url","10.46.25.167:1099");<br /> <br /> //InitialContext namingContext = new InitialContext();<br /> InitialContext namingContext = new InitialContext(hashtable);<br /><br /> ConnectionFactory dmConnectionFactory = null;<br /> <br /><br /> // Lookup the PDF Manipulation service<br /> Object pdfObject = namingContext.lookup("PDFManipulation");<br /><br />Line 82 => pdfConnectionFactory = (ConnectionFactory) PortableRemoteObject.narrow(pdfObject,ConnectionFactory.class);<br /> <br /> <br /> <br /> // Use the pdfConnectionFactory object to create a PDFFactory object<br /><br /> PDFFactory mPDFFactory = PDFFactoryHelper.narrow((org.omg.CORBA.Object)pdfConnectionFactory.getConnection());<br /> // Create a FileDataBuffer object to store an existing PDF document by<br /> // calling the DataManager objects createFileDataBufferFromUrl method.<br /> // Reference a PDF document named Loan.pdf<br /> DataManager mDataManager = DataManagerHelper.narrow((org.omg.CORBA.Object)pdfConnectionFactory.getConnection());<br /><br /> <br /> //FileDataBuffer pdfFile = mDataManager.createFileDataBufferFromUrl("http://<Application Server URL>:AppPort/LoanApp/Forms/Loan.pdf");<br /> FileDataBuffer pdfFile = mDataManager.createFileDataBuffer("y:/backup/test_bo.pdf");<br /> // Open the PDF object using the PDFFactory object<br /> PDFDocument pdf = mPDFFactory.openPDF(pdfFile);<br /> <br /> //pdf.setReaderDownloadMessage("Please download the latest version of Adobe Reader from our web site", "http://www.MyCorp.com");<br /> String[] formRights = new String[] {FORM_ADD.value};<br /> Credential cred = new Credential("Enabl

Apparently the msg was to long.



So here is the error-msg:



Error generated:



java.lang.ClassCastException

I have to do exactly the same procedure but from .NET side. Do you have any solution?



How far have you got?



Thanks,

Hi,



it's not possible to access by CORBA the application outside the container. So you have to deploy the AdobeLifeCycle-application in the same container as your sample-code.



I other words, your can't use corba for remote access. (The question 'Why do they use CORBA for?' is still unanswered..).



We solved the problem by writing a servlet we deployed localy . We use the servlet for handling our call. We needed only to be able to annotate a PDF.



If you use more (advanced) features, you should consider writing a SOAP-interface for your program-calls.

Hi,

I'm not a java specialist, and I want to use an newly installed version of ReaderExtension 7.2.2 to get rid of an old server runnning ReaderExtension 6.x.

I successfully installed it and transformed a PDF document into a "comment and annotation free" PDF with the web interface.

In our production environment we need to call remotely the Application Server where ARES is deployed only for freeing annotations and comments.



Can you please give me your servlet code as a sample code



Thanks in advance

Hi,



here is the code we used for the servlet. You have to deploy the servlet in the same container as the adobe-lifecycle. Otherwise it won't work.
