Hello Ed,

are there any news on this topic:
http://dev.eclipse.org/newslists/news.eclipse.tools.emf/msg1 8478.html ?

I mean: Is it possible to run JMerge completely standalone (that is: even
without some eclipse workbench location)?
I had a quick look at the code and saw, that AstHelperFacade uses JavaCore
to get default options. Maybe this is the only place that causes traouble
in standalone. But I am not to deep in that...

Best Regards,
Stefan.

Stefan,

I think JDT core's AST works stand alone but I've really not looked
into it nor had the time. It's worth exploring and it might be possible
to make simple changes that avoid any class loading problems.

Okay, thank you. I will give it a try in the next days...

I had some success with code like this. Perhaps its useful for others.
Please note especially setting of JavaCore options:

public void merge(File src, File target) {
JControlModel model = new JControlModel();
ASTFacadeHelper astFacadeHelper = new ASTFacadeHelper() {
Map options;

@SuppressWarnings("unchecked")
@Override
public Map getJavaCoreOptions() {
if (options == null) {
options = new HashMap();

options.put(JavaCore.COMPILER_COMPLIANCE,
JavaCore.VERSION_1_6);
options.put(JavaCore.COMPILER_SOURCE, JavaCore.VERSION_1_6);
options.put(JavaCore.COMPILER_CODEGEN_TARGET_PLATFORM,
JavaCore.VERSION_1_6);
options.put(JavaCore.COMPILER_PB_ASSERT_IDENTIFIER,
JavaCore.ERROR);
options.put(JavaCore.COMPILER_PB_ENUM_IDENTIFIER,
JavaCore.ERROR);
options.put(JavaCore.COMPILER_CODEGEN_INLINE_JSR_BYTECODE,
JavaCore.ENABLED);

//!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
options.put(JavaCore.COMPILER_DOC_COMMENT_SUPPORT, JavaCore.ENABLED);


Map cfo = DefaultCodeFormatterConstants
.getEclipseDefaultSettings();

options.putAll(cfo);

options
.put(
DefaultCodeFormatterConstants.FORMATTER_BLANK_LINES_AFTER_PA CKAGE,
"1");

}
return options;
}

};

String mergexml = this.getClass().getClassLoader().getResource(
"merge.xml").getFile();

model.initialize(astFacadeHelper, mergexml);

JMerger jMerger = new JMerger(model);

String sourceCnt = "package jmerge; \npublic class Foobar{
java.lang.String s; int x; \n\n/**\n * @generated\n */\npublic void
doIt(){System.out.println(\"Hello\");}}";

jMerger.setSourceCompilationUnit(jMerger
.createCompilationUnitForContents(sourceCnt));

String targetCnt = "package jmerge; \npublic class Foobar{ public double
y; private int x;public void doIt(){} }";

jMerger.setTargetCompilationUnit(jMerger
.createCompilationUnitForContents(targetCnt));


jMerger.merge();


String result = jMerger.getTargetCompilationUnit().getContents();

System.out.println(result);

}
