This happened a long time ago but as I recall the correct syntax is
java -Djava.rmi.server.codebase=file:suncertify/server/
-Djava.security.policy=fbn.policy
suncertify.server.DataServerImp
DataServer suncertify/db/db.db
i.e. you will notice that it is file: , not file:/ . It was a relative directory not absolute . That made the difference . Also the codebase wasn't required on the client side .
So , you guys are telling me you don't know how big the project is or what ? Maybe it's not that big and you don't want to say .
I run the server and I type http://localhost:7001/console in my browser . I get the prompt for username and password and the console appears to start for a brief second and then disappears . Does this sound familiar to anyone ?

No , no tools . I want experience coding a real project . Is this design project big enough , I am asking the experienced coders out there .
Hi , I want to know how big is the project part of the certificate . How many classes or beans are involved ? The reason I ask is I would want to translate the design afterwards to code but only if it is substantial and worthwile . I'm trying to get entry-level job but without good hands-on project experience it's hard . Developer certificate was a little dissappointing , the coding wasn't as large as I thought it would be . As in Developer there's probably a lot of flexibility in terms of how the specifications/requirements are followed ? In that case , just what would be the approx. minimum amount of classes to fulfill the requirements here ? Because I find it hard to do much more than is asked anyway without specific instruction .
Thanks .
I'm trying but not getting anywhere . Where do you put the final JAR file in Weblogic ? Do you just plop it in C:\bea\wlserver6.1\config\mydomain\applications or do you need to do something extra ? I've read the docs ten times , still not getting anywhere . When I run my server , the output doesn't mention my new deployment or anything .
I jarred my class files up . They're all in the examples/helloworld directory . Another directory is META-INF where I put ejb-jar.xml and weblogic-ejb-jar.xml .
Then I run weblogic.ejbc on this jar file and I throw the resulting jar file in :\bea\wlserver6.1\config\mydomain\applications . As far as I can tell jndi-name and client call are the same .
And I can't get the console to run so I am hoping someone knows how to deploy manually .
Thanks .
You use the following symbol : ${/}
to represent system independent file separators .
It's hard to say ruilin . The rest of the spec lists what MUST be in your assignment , not what could be .
Anyway at this point I think I'm not going to work on this anymore . I'll let you know if I pass though .
Unfortunately I get "no stack trace available" .
But everything works fine when I use a web server and http URLS. When I switch over to file URLs I get this crazy error at the point where I modify a record . i.e. DataInfo object is being sent to the server . Why it is having trouble UnMarshalling or why there is AccessControlException is beyond me . I'm starting to think it has something to do with a glitch of some kind .
I'm just not sure whether or not I should hand in my assignment as is . Maybe the markers are using a web server anyway ?
Thanks for the reply . It seems no one is concerned about the adding part then . It just seems to me that "should keep scheduled flight information" implies that "keep" means maintain ,update . Otherwise if you analyse the whole quote :
"This application should keep scheduled flight information for a number of airlines and routes,and it should provide a convenient way to search for and book flights that might suit customer's requirements"
It has THREE requirements . 1. search 2. book AND 3. keep scheduled info .
So the question is , what does "keep" mean ?
How many of you have the following spec :
"This application should keep scheduled flight information for a number of airlines and routes,and it should provide a convenient way to search for and book flights that might suit customer's requirements"
My concern is this sounds like I have to implement updating and adding records . Anyone else have the same spec and came to the same conclusion ?
Any comments on the following ?

I'm going completely bonkers over here .
I was going to upload my assignment today but something screwy is happening . My program is currently working fine when I use
http URLs and a web server for my codebase . And yesterday I had it working fine with file URLs .
But for some reason it's not working anymore : I get a crash when attempting to book . It's RemoteException and it occurs precisely at
database.modify(record)where record is DataInfo type .
The nested exceptions are UnMarshalException and NoClassFoundException . So it appears the server is not unmarshalling DataInfo record properly because it can't find the class ?
It works fine under my web server so I just don't get it . If anyone has an idea please let me know , that's all I can say .
I have my policy file set with FilePersmissions pointing to db.db (which I have put in two locations) .
Now , since this policy file is set for good ( we are not to require editing by the examiners ) , the location of the files is set for good also . So the examiner can not be using a different db.db location relative to the current directory .
But then the assignment requirement that you be able to choose a location of db.db at start-up is slightly useless then .
Does this make sense or am I missing something ?
