Dear all, we are trying to build our GUI using Google Web Toolkit and ROSJAVA. Unfortunately we are facing problems with integration of ROSJAVA into Google Web Toolkit apps. Obviously gradle and a bootstrapping process is used to configure and start ROSJAVA applications. Unfortunately GWT offers it's own entrypoint for applications. We tried to add the ROSJAVA jars to the project and tried to use the NodeMainExecutor from ROS to start a thread within the GWT server to take care for all ROS tasks. Unfortunately due to obvious reasons this failed with ClassNotFoundException (no bootstrapping has been performed). Now we got stuck. Is there a way to create ROSNODEs from within a Java project without using the Java Rosrun and can the project be manually configured without using gradle and a bootstrapping process, so that i can use the ROS jars within my java projects avoiding ROSJAVA build process. Are their asny other ways so solve te problems like building GWT apps also via gradle? (i see problems since the entrypoint for GWT apps is the GWT compiler) Thank you in advance.
