restful service with int array

["chengy@action" <15...@qq.com>]

hi,I publish a restful service with:

@POST
@Path("/removeProcessInstances/{processInstanceIds:.*}")
public void removeProcessInstances(@PathParam("processInstanceIds") int[]
processInstanceIds) throws SDKException {
//remove...
}

but,when i call the service like "xxx/removeProcessInstances/11,22",cxf
handlers "11,22" as string, how to call it? is this right?Thanks

It took me a bit of time to refresh why it was happening, you can't make 
it work by default, you will need to register JAX-RS 2.0 
ParameterConverter for doing it;

This would if you had something like

"xxx/removeProcessInstances;id=11;id=22"

where 'id' is repeated a number of times, in this case this would be a 
matrix parameter, but when you have "id=1,2" the runtime itself does not 
know how to convert "1,2" into int[] because ',' is a custom separator, 
it can be something else in other cases.

Thus in such cases you need to use custom ParamConverters
