Hi Michael, Great that you are trying to fix JBIDE-611. Got some comments on that: 1) Any way that this could be done in the hibernate tools plugin instead of the unrelated diagram plugin ? (I don't see you are using any new plugins for this so should be in the core of hibernate tools imo) +++ Yes, hibernate tools core is better place for that code but I thougth I can't change this plugin. If I can't use the original code of core how I can do it? Should I ask you to make some changes or can I do it myself? +++ 2) Please don't use bogus id's in our plugin.xml like: com.xyz.runXYZ, it should be something stable and resembling the other id's. +++ Fixed. +++ 3) This code looks like it is assuming everything are done in mapping files and with a cfg.xml file; is that correct ? What about annotated classes? +++ I remember comment in jira about it. I work with this point now. +++ 4) you have copied a large chunk of code from hibernate tools plugin to locate the default project; why don't you use the existing code for that ? +++ You speak about code ILaunchManager launchManager = DebugPlugin.getDefault().getLaunchManager(); ILaunchConfigurationType launchConfigurationType = launchManager.getLaunchConfigurationType( "org.hibernate.eclipse.launch.ConsoleConfigurationLaunchConfigurationType" ); ILaunchConfiguration[] launchConfigurations; try { launchConfigurations = launchManager.getLaunchConfigurations( launchConfigurationType ); for (int i = 0; i < launchConfigurations.length; i++) { // can't believe there is no look up by name API ILaunchConfiguration launchConfiguration = launchConfigurations[i]; if(launchConfiguration.getName().equals(consoleConfiguration.getName())) { proj = ProjectUtils.findJavaProject(launchConfiguration.getAttribute(IConsoleConfigurationLaunchConstants.PROJECT_NAME, "")); } } } catch (CoreException e1) { ViewPlugin.getDefault().logError("Can't find java project.", e1); } in OpenMappingActionDelegate class. Is that correct? +++ /max
