Extension debugging with Eclipse

[tmakita]

I'm developing custom element insertion framework extension via Java & Eclipse. By following the below URL I tried to debug my extension in Eclipse from Oxygen.
Debugging an Oxygen SDK Extension Using the Eclipse Workbench
https://www.oxygenxml.com/doc/versions/ ... g-sdk.html
The XML file that describes the extension.
xxx-frameworks\externalAuthorActions\bookref.xml

Code: Select all

<a:authorAction xmlns:a="http://www.oxygenxml.com/ns/author/external-action"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.oxygenxml.com/ns/author/external-action http://www.oxygenxml.com/ns/author/external-action/authorAction.xsd"
	id="bookRef">
	<a:name>分冊間参照</a:name>
	<a:description>分冊間参照を挿入します</a:description>
	<a:largeIconPath href="./icons/bookref.png"/>
	<a:smallIconPath href="./icons/bookref-small.png"/>
	<a:operations>
		<a:operation id="com.antennahouse.oxyutil.operation.ExtXrefOperation">
			<a:xpathCondition>//*</a:xpathCondition>
			<a:arguments>
				<a:argument name="bookrefpath">${xpath_eval(concat("${pd}", '/../../book-ref/book-ref.xml'))}</a:argument>
				<a:argument name="fragment">
					<extxref volref="${extxrefVolref}" ref-style="${extxrefFormat}" refid="${extxrefId}" pattern="${pattern}">${extxrefTitle}</extxref>
				</a:argument>				
				<a:argument name="insertLocation"></a:argument>
				<a:argument name="insertPosition"></a:argument>
			</a:arguments>
		</a:operation>
	</a:operations>
	<a:accessKey/>
</a:authorAction>

bookref.png is displayed in the Oxygen toolbar, so I assume that this framework is surely recognized from Oxygen,
The class that implements AuthorOperation:

Code: Select all

public class ExtXrefOperation implements AuthorOperation{
    ExtXrefDlg exd = null;
    private static final String ARG_FILEPATH = "bookrefpath";
    private static final String ARG_INSERT_FRAGMENT = "fragment";
	@Override
	public void doOperation(AuthorAccess authorAccessarg, ArgumentsMap arguments)
			throws IllegalArgumentException, AuthorOperationException {
		Dialog.informationDlg(null, "Hello World!");
		if (exd == null) {
			String bookrefPathString = (String)arguments.getArgumentValue(ARG_FILEPATH);
			String fragmentExtxref = (String)arguments.getArgumentValue(ARG_INSERT_FRAGMENT);
			//exd = new ExtXrefDlg(bookrefPathString);
		} else {
			exd.setVisible(true);
		}
	}
	@Override
	public String getDescription() {
        return "Insert \"extxref\" element from dialog";
	}
	@Override
	public ArgumentDescriptor[] getArguments() {
	    ArgumentDescriptor args[] = new ArgumentDescriptor[] {
	    		new ArgumentDescriptor(ARG_FILEPATH, ArgumentDescriptor.TYPE_STRING, "The relative path of book-ref.xml from project path."),
	    		new ArgumentDescriptor(ARG_INSERT_FRAGMENT, ArgumentDescriptor.TYPE_STRING, "extxref placeholder template")
	    };
	    return args;
	}
}

The .class files folder is directly assigned in the Document Association Class path dialog.



But one I invoke extension class form Oxygen toolbar icon, I got the following error message.

When I generates .jar file from Eclipse and set it framework resources folder, I could get my extension work.

Are there any advices to debug extenion in Eclipse IDE from Oxygen??
Any suggestions are welcome!
Thanks and regards,

Hi,
So the documentation you linked says:

In the Classpath tab, add a reference to your Project's classes directory and in the Extensions tab,

This would mean you just need to add in the Classpath list a reference to your "bin" folder, but instead you seem to refer individual subfolders from the bin folder.

> This would mean you just need to add in the Classpath list a reference to your "bin" folder
After changing the classpath to bin folder, I could get the "Hello World!" dialog.
> Add a breakpoint in one of the source Java classes.
However, the break point of Eclipse did not seem to work.

Hi,

However, the break point of Eclipse did not seem to work.

Not sure about this one, Oxygen loads these extensions in a separate class loader, maybe this breaks Eclipse's ability to know in which class the breakpoint is.

Thank you, I got it!
