and my schemacrawler-context.xml is like

<bean id="outputOptions" class="schemacrawler.tools.options.OutputOptions">
    <property name="outputFormatValue" value="DOT" />
    <!-- <property name="outputFile" value="scOutput.txt" /> --><!-- This should be given(writer not file) given from the program. -->
</bean>

it is not working for DOT as well as dot

Answer 1

Khader,

For web output, you have a few output options available out of the box from SchemaCrawler. One option is to generate output in "htmlx" format, which will give you an ER diagram embedded in HTML, in a single file. Another option is to use "png" format to generate a PNG file. It is hard to see what executable you have in the Spring context, since you have not included this key information in your question. I would advise you to use the GraphExecutable.

Please note that in order to generate the ER diagram, you will need GraphViz installed on the web server. GraphViz will always generate a file, and cannot use a Java writer. So, please use the most appropriate constructor for OutputOptions .

If you like, you can have SchemaCrawler generate DOT format. Again, please use the most appropriate constructor for OutputOptions . You do not need GraphViz for this. You can use viz.js to visualize the DOT file using JavaScript.

Hope this helps.
