Re: [ajdt-dev] partially OT, AJDT & RAD

[Marco Mistroni <mmistroni@xxxxxxxxx>]

Hello Matt,

    i am gettin gback  so late after holidays.... still couldn't get 2 aspects for 2 different projects to intercommunicate...

i really appreciate if you could try to test this 2 aspects on 2 different projects......

 

here's the situation..

i have 2 projects, ngenEJB and ngenWeb.

both of them are aspectJ enabled.

i have written one aspect in ngenWeb and one aspect in ngenEJB project

 

what i need is to have the aspect in ngenEJB to call a method on the aspect in ngenWeb.

 

I have tried to

- set the aspectPath of ngenEJB to      ngenWeb\sources\com.myaspect

- set the aspectInPath of ngenEJB to   ngenWeb\WEB-INF\classes\com (since i have also other packages under classes)

 

but still when i compile my ngenEJB aspect, i got a  com.myaspect could not be resolved....

 

i attach both aspects, though the real prblem i suspect are the settings....

i am using RAD 6.0 wtih AJDT 1.2.0

 

would you mind giving me little help?

 

thanx in advance and regards

   marco

Hi Marco,

Sorry to hear things aren't going smoothly for you.
You probably want to use "ngenWeb/Webcontent/WEB-INF/classes" as the
path (without the "com" at the end) if that is the root of the class
path folder.
To refer to aspects from the other project, rather than just apply
them, you also need to make them available on the regular classpath.
If you still have problems, please create test projects representative
of your setup and attach them to a bugzilla report, and we can then
try to get them working ourselves.

Regards,

Matt.
