Sample programs (Java)

Using the command line (Java)

A sample application has been provided to illustrate the use of the Document Composer (for Java), from the command line.

<path-to-mathflow-sdk>/java/samples/document_composer_cmd.bat (Windows) <path-to-mathflow-sdk>/java/samples/document_composer_cmd.sh (non-Windows)

About the Script

The Document Composer batch file (or shell script) calls DocumentComposer with several options. It contains the following command (formatted for clarity):

java -classpath .;../MathFlow.jar
com/dessci/mathflow/sdk/composer/DocumentComposer
-license dessci.lic
-inputdoc input.html
-outputdoc output.xhtml

Caution

IMPORTANT NOTES:

  • This required .jar files needs to be on the classpath:

    • MathFlow.jar (all MathFlow SDK classes)

  • Within the MathFlow jar file, the DocumentComposer program is located at com/dessci/mathflow/sdk/composer/DocumentComposer.

  • Your license, dessci.lic, is a FlexNet license file that is located in the same directory as the Document Composer batch file (or shell script). This option is always required.

  • The inputdoc file to be processed is named input.html, and is located in the same directory as the batch file or shell script. This option is always required.

  • The name of the outputdoc file will be output.xhtml, and is located in the same directory as the batch file or shell script.

  • The image generated by the MathML in the inputdoc file, input1.gif, will be written to the default input_images directory. If this file already exists, it will be overwritten.

For a complete list of the command line options, see Command line parameters.

Sample Java Application

The sample Java program below illustrates how to use the DocumentComposer class to process a document with MathML. The source code is provided so that you can experiment with different techniques for use in your own programs.

Prerequisites for Running the Program

  • Java 1.6 or higher

  • The dessci.lic file should be in the same directory as the sample code batch files or shell scripts. If it's not, be sure to enter the correct path in the appropriate spot in the application window.

  • The required .jar file needs to be on the classpath: MathFlow.jar (all MathFlow SDK classes).

Running the Program

<path-to-mathflow-sdk>/java/samples/document_composer_app.bat (Windows) <path-to-mathflow-sdk>/java/samples/document_composer_app.sh (non-Windows)

The sample program allows you to change the input parameters used to process an input document with MathML (see below). After changing the input parameters and telling the program where to save the generated images, click the Generate Output Document button.

When the Document Composer successfully processes the document, it will display a confirmation dialog similar to this one:

mathflow_sample_java_document_composer_confirmation.png

Dismiss the dialog to see the application window:

<a><img></img></a>

Source Code

The source code for the sample program is located in:

<path-to-mathflow-sdk>java/samples/com/yourcompany/samplecode/composer/DocumentComposerApplication.java

About the Script

The batch file (or shell script) calls DocumentComposerApplication.

java -classpath .;../MathFlow.jar com/yourcompany/samplecode/composer/DocumentComposerApplication

Note the source code for the sample program is located in the following directory:

<path-to-mathflow-sdk>java/samples/com/yourcompany/samplecode/composer/DocumentComposerApplication.java

Programming Notes

The main functions/subroutines in this program are as follows:

processDocument()

This function does the following within a Try/Catch block:

  • Calls setOptions to set the options for the Document Composer using the values of the program controls

  • Calls the method to process the input document

setOptions()

This function does the following:

  • Sets the value of each option for the Document Composer from the corresponding program control

  • The general strategy in the sample application for handling exceptions in the SetOption methods is:

    • If an option is required (i.e., license or inputdoc) and an exception is thrown by the SetOption method, throw an exception with the error message returned from the SetOption method

    • If an option is optional and has a default value (e.g., pointsize), catch any exception thrown by the SetOption method, retain the warning message for display later and continue processing, using the default value for that option

    • If an option is optional and does not have a default value (e.g., logfile), catch any exception thrown by the SetOption method, retain the resulting message for display later and continue processing

Note that this only one way in which the options for a Document Composer can be set. Another possible approach would be to call each set method when the value of a program control changes.

getOptions()

This function does the following:

  • Sets the value of the program controls from the corresponding options of the Document Composer

readOptions()

This function does the following within a Try/Catch block:

  • Calls the method to read the options from an XML file

  • Calls getOptions to set the value of the program controls using the options for the Document Composer

saveOptions()

This function does the following within a Try/Catch block:

  • Calls setOptions to set the options for the Document Composer using the values of the program controls

  • Calls the method to save the options to an XML file
