Dear Kish I've already successfully used an EclipseEngineOptions object. The problem with the automatic deployment is that the EclipseEngineOptions object needs the absolute path to the ECLiPSe installation but the deployed bundle does not have one. In other words, the environment does not provide an absolute path the the Java code. For this reason, we had the idea to move the ECLiPSe system to a known directory, e.g., a subdirectory of /tmp. Then, the EclipseEngineOptions object could be supplied with a valid path. Thanks, Ulrich Reply of Kish in an other mail: The ECLiPSe directory for an embedded ECLiPSe can be specified as an option when you start embedded ECLiPSe, and the way to do this from Java is described in the embedding and interfacing manual's `Configuring an EclipseEngineOptions onject' section: http://www.eclipse-clp.org/doc/embedding/embroot048.html#toc55 You probably also want to use the eclipse_rt package rather than the eclipse_basic package with your distribution -- assuming you don't want/need a runtime environment where ECLiPSe is deployed. I assume this should also address the issue in your previous post as well: you can include ECLiPSe in a subdirectory of your Java application (I assume Java allows this in the Java bundle you mentioned?), and you can set the ECLiPSe directory option when you start the embedded ECLiPSe from within your application. This should be independent of the OS you are using.
