I developed an API for accessing web services for jsr 172. It is not Sun's j2me webservice implementation but most related to that. It works well with wireless tool kit. But with real phones it gives the following error.
Nokia3650- I could installed the jar file but while running it throws "Application error , illegal state exception"
Nokia 6600- While installing it throws "Authorisation fail"
With which phones I can test my implementation. And what is the MIDP version I should use to create the jar file. And let me know whether there are any security procedures to run this implementations with real phones.
