Convert Eclipse RCP 3.7 Application to RAP 2.2 [message #1270691]

Hi,

We have developed Eclipse RCP application using Eclipse Indigo(3.7), now we have to migrate the application to RAP to support it on web also. I wanted to know can we migrate eclipse 3.7 application to RAP 2.2 or not?

If the conversion is not possible with RAP 2.2 then is it a good idea to use RAP 1.4 for indigo or not? as i think it is very old version of RAP with very less features.

Thanks in advance
Gaurav

Hi Gaurav,
to single source your application with RAP 2.2 highly depends on the
application itself. Some of the SWT/JFace API are missing in RAP (like
StyledText, Tracker, draw on Controls...) and you will get a compile
errors. Also you have to take care about multi user nature of RAP -
replace static fields/classes with UI session singletons where
appropriate. RAP workbench port is still based on RCP 3.7. See our
workbench demo at [1].

Hi Ivan,

Thank you for the response, yes i am fine with the compilation errors for few components, the only doubt is in RAP portal the target platform for RAP 2.2 is mentioned as eclipse 3.8 to 4.3, so i am not sure whether it will support 3.7 architecture. As our RCP application is based on Eclipse 3.7 with features like perspectives, extension point and in eclipse 4.3 this architecture has been changed so is it possible to directly migrate the application from RCP 3.7 to RAP 2.2 with features like Perspectives, Wizards, Basic controls(Text, Label, Combo, Radio buttons) or we need to make lots of efforts to change the application.

We have tried to migrate one small part of the application from RCP to RAP 1.4 and we found that it can be done by changing small portion of the code, is it also applicable for RAP 2.2 or we have to first adapt the eclipse 4.3 architecture and then only we can move to RAP 2.2.

Thanks in advance.

Gaurav

Hi Gaurav,
RAP 2.2 JFace/Workbench/Forms ports are still based on RCP 3.7. You
should not have any problems with the architecture.
Best,
Ivan
