Convert, merge and generate DOCX, PDF and XML files automatically in an Appian process

Key Features & Functionality

  • PDF from single DOCX with Fonts
    • Convert multiple DOCX files into a single PDF. Please note that the translation from DOCX to PDF is not always 1:1. The template may need to be tweaked or simplified to achieve the desired results.
  • PDF from DOCX without Fonts
    • Convert multiple DOCX files into a single PDF. Please note that the translation from DOCX to PDF is not always 1:1. The template may need to be tweaked or simplified to achieve the desired results. This will not support fonts.
  • PDF from XSL-FO Transformation
    • Uses XSLT to convert an XML to XSL-FO which is then converted to PDF
  • PDF from HTML
    • Converts an HTML document into a single page PDF.
  • PDF from HTML Transformation
    • Uses XSLT to convert an XML to HTML which is then converted to PDF
  • Text Doc from XSLT
    • Uses XSLT to convert an XML to a plain text document (such as HTML, another XML doc, etc).
  • DOCX from XHTML With Styling
    • Converts a valid XHTML file into a DOCX, allowing you to provide your own template file for style reference. Useful for creating dynamic documents that are editable
  • DOCX Merge
    • Merges one or more DOCX files together. If a header or footer exists in any document, they will be removed during the merge process.
    • A configurable separator can be specified: none, line break or page break

  • Hi

    We have updated the plugin version from 1.8.5 to 1.87. After upgrade document generation workflows are breaking with thefollowing error.

    com.appiancorp.suiteapi.common.exceptions.AppianRuntimeException: com.appiancorp.suiteapi.common.exceptions.AppianException: java.lang.NoClassDefFoundError: com/lowagie/text/DocumentException

    Please fix this issue as it is impacting production deployment.

  • Hello,

    We are planning to upgrade this plugin from 1.4.1 to latest version 1.8.7. 

    DOCX from XHTML smart service is working in older deployed plugin but once we deploy new version 18.7. we are getting below error:

    javax.resource.spi.work.WorkCompletedException: java.lang.NoClassDefFoundError: com/lowagie/text/DocumentException

    iText.jar exist in the older version (DynamicDocumentGen-1.4.1), however, missing in newer version(dynamic-document-generator-1.8.6 & dynamic-document-generator-1.8.7), which is required for generating docx.

    We tried adding iText.jar in latest 1.8.7 version and it is working. 

    Any plans to add back the iText.jar back in official release of this plugin?

    As per release note of 1.8.6, "Removed dependency on iText", can you pelase suggest how can we get the DOCX to XHTML working back without iText.jar? 

  • Looks like it's an embedded svg and <instream-foreign-object/> that is the problem.   Again, it works in apache fop just not when that code is hosted in this plugin apparently.

  • I've run apache fop 2.5 locally against my xsl-fo and xml and I get my pdf with an embedded svg image but using the same xsl-fo and xml using Appian and this plugin results in a generic java error "An error occurred in executing an Activity Class."  Does this plugin handle embedded images?    

  • in reply to vik

    Can you confirm that the XslParameter CDT is available? Is it possible that you might have deleted the CDT?

    Note that as of 21.4 Smart service plug-ins now load successfully if the related CDT has the same structure, even if the CDT has a different version number (e.g. it was imported in a package or deleted and recreated)

    The error will go away as long as the XslParameter CDT exists.
