Is it possible to call a COM API from Java (specifically the HP/Mercury Quality Center OTA API)? If so, what's the best way?
Is something like JACOB appropriate?
Code fragments would be helpful for the basics :-)
回答1:
jacob : yes, http://sourceforge.net/projects/jacob-project/ is an active project that will suite your purpose pretty well.
you can see multiple examples : http://jacob-project.wiki.sourceforge.net/Event+Callbacks
but if you want something that is more tested and are willing to pay money, then go for http://www.nevaobject.com/_docs/_java2com/java2com.htm.

maybe you should have a look at http://qctools4j.sourceforge.net/ it's a java library used by qclylyn (http://sourceforge.net/apps/mediawiki/qcmylyn/index.php?title=Main_Page) to retrieve defects from QC.
unfortunately the COM bridge doesn't work for linux as it loads jacob dlls

after a comparison of all the above, none was totally satisfactory.
the most complete solution is in https://github.com/java-native-access/jna
now.
It supports,
- getting interface to a running COM object
- starting a new COM object and returning its interface
- calling COM methods and returning results
- optional separate COM thread handling
- ComEventCallbacks
- RunninObjectTable queries
- lowlevel COM use
- util / high level java proxy abstraction
E.g.
MsWordApp comObj = this.factory.createObject(MsWordApp.class);
Documents documents = comObj.getDocuments();
_Document myDocument = documents.Add();
String path = new File(".").getAbsolutePath();
myDocument.SaveAs(path + "\\abcdefg", WdSaveFormat.wdFormatPDF);
comObj.Quit();

j-Interop is a Java-COM bridge: j-Interop. It's written in pure Java and licensed under the LGPL v3. It uses the DCOM wire protocol to call COM objects as opposed to the JNI approach used by JACOB.
回答5:
You can use J-Integra COM2JAVA tool. The com2java tool generates Java "proxy" classes and interfaces that correspond to the coclasses and interfaces contained in a COM type library. It effectively generates a Java API which you can use to access a COM component from Java.
