[ros-users] ROSJAVA in Web Projects

[Tim Beyl]

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.

Kind regards,
Tim
