    Legacy JSP Sample

    Installation

    This topic contains steps for how to install the legacy JSP sample on Linux and Windows.

    NOTE: JDK 1.7 and JRE 1.7+ are required.

    1. Run the appropriate "Client Installer" for your OS, Windows or Linux.
    2. Install Apache Tomcat.
    3. After installation is complete, launch Tomcat Manager.
    4. In the WAR file to deploy section, select Choose File.

    5. Select PCCSample.war file to upload from the installation location:

      • For Windows: C:\Prizm\Samples\jsp\target
      • For Linux: /usr/share/prizm/Samples/jsp/target

    6. Click Deploy.

    7. PrizmDoc Server web tier will be deployed on your Tomcat server. The deployed app may be found in the following location:

      • For Windows: C:\Program Files\Apache Software Foundation\Tomcat 7.0\webapps
      • For Linux: /var/lib/tomcat7/webapps

    8. Give read/write permissions to the "Documents" folder, the "markup" folder and the "markupLayerRecords" folder. Give read permissions to the "imageStamp" folder. These folders are installed on the following location:

      • For Windows: C:\Prizm\Samples\
      • For Linux: /usr/share/prizm/Samples

    9. Now you can browse to http://localhost:8080/PCCSample in your browser to see the JSP sample. See the JSP Directory Structure for more information on where these files are located.

    Configure JSP Web Tier with SELinux

    If you are running the JSP Web Tier on Security-Enhanced Linux you may experience issues when loading documents in the Viewer. The Web Tier needs to contact the PrizmDoc Server but SELinux disallows Tomcat processes from making outbound connections by default. You can run the following command to make the Tomcat domain permissive and allow the Web Tier to function normally with Tomcat:

    semanage permissive -a tomcat_t

    Overview

    From the splash page you have three options:

    1. Choice of Viewer:

      • You can choose to load either the Full Viewer, the Book Reader, or the Comparison Viewer.

        Select a sample document -OR- upload a document:

      • You can choose any of the 5 sample documents (Word, PDF, CAD, Tiff, or JPEG).
      • Or, you can upload a document from an arbitrary location on your computer. Note that dragging and dropping a file on this page is not supported in Internet Explorer 8.

    2. Full Viewer:

      If you select Full Viewer on the splash page, then documents will be viewed with the full-featured, out-of-the-box responsive Viewer:

    3. Book Reader:

      If you select Book Reader on the splash page, then documents will be viewed with the book reader. The book reader demonstrates how the Viewer can be heavily customized:

    4. Comparison Viewer

      NOTE: This feature requires a Microsoft Office enabled PrizmDoc License.

      If you select Comparison Viewer on the splash page, then you can upload two Word (.doc or .docx) files to be compared in the Viewer. The Comparison Viewer shows how two Word documents can be reviewed and compared using PrizmDoc:

    JSP Directory Structure

    The jsp samples are installed under /usr/share/prizm/Samples/jsp/Sample/public_html. This folder contains 6 sub-folders, one folder for each of the four samples (full Viewer, book reader, e-signer and e-signer template designer) and two folders for the splash pages (main splash page and the e-sign splash page):

    Each of the sample folders are completely self-contained, meaning that they contain all of the files needed to run the sample. Furthermore, with the exception of a few project files and build files, the sample folders contain only the files needed to run the sample.

    Folder contents: common

    File / Folder Description
    src/com/accusoft/pccis/sample/pas and src/com/accusoft/pccis/sample/html5 Contains classes that support the communication between the Viewer and PrizmDoc Application Services. While the code for the classes can be modified as needed, modifications should be done with care.
    public_html/WEB-INF/web.xml Contains web tier settings.Some of these settings define the connection for the PrizmDoc Application Services. See more on the Configuration with web.xml section below.

    Folder contents: full-viewer-sample

    NOTE: The full viewer (with the comparisonMode configuration parameter set to true) is used for document comparison.

    File / Folder Description
    viewer-assets folder Contains the essential JavaScript, CSS, fonts, and images that make up the Viewer.
    viewer-assets/src folder Contains Less, icons, languages, and HTML templates that can be used to build the Viewer CSS and customizations. This folder is non-essential, and does not need to be re-distributed.

    predefinedSearch.json This data file contains information defining search queries that will appear as selectable items in the full Viewer.
    NOTE: This file is consumed by the page index.jsp and the JSON is injected into the HTML that is returned by index.jsp. Ultimately, the predefined search terms are provided as a JavaScript hash, when the Viewer is created.
    redactionReason.json This data file contains information defining redaction reasons that are available in the Viewer.
    NOTE: This file is consumed by the page index.jsp and the JSON is injected into the HTML that is returned by index.jsp. Ultimately, the redaction reasons are provided as a JavaScript hash, when the Viewer is created.

    Configuration with web.xml

    The file web.xml is used to configure the connection settings between the web tier and PrizmDoc Application Services. The file can be found at: public_html/WEB-INF/web.xml. This file is self-documenting, but a little information about the configuration options is given below.

    Option Description
    DocumentPath The sample pulls named documents from this location. The DocumentPath must have read/write permissions in order for the file drag and drop functionality of the splash page to work.
    PrizmApplicationServicesScheme Specifies the scheme (http or https) to use when connecting with PAS.
    PrizmApplicationServicesHost Specifies the host to use when connecting with PAS.
    PrizmApplicationServicesPort Specifies the port to use when connecting with PAS.

    All settings are configured using the <context-param/> element. Here is an example of how it would look on the web.xml file:

    Example

    <context-param>
        <description>Prizm Application Services Scheme</description>
        <param-name>PrizmApplicationServicesScheme</param-name>
        <param-value>http</param-value>
</context-param>
