Hi Stanley
i have try to play a little with packages using several scenarios having as
playground my Article about Birt and POJOs [1] and this why i have recieve
some comments about this.
Scenario 1
----------
POJO's classes exist in :
C:\JProgramFiles\eclipse-SDK-3.0.2-win32\eclipse\plugins\org .eclipse.birt.report.viewer_1.0.0\birt\WEB-INF\classes\{pack age
structure}
access those POJOs in report's open method like:
<snip>
count = 0;
cf = new Packages.gr.osmosis.report.data.ContactListFactory();
c = cf.createContactList();
</snip>
this scenario work fine
Scenario 2
----------
POJO's classes exist as .jar in :
C:\JProgramFiles\eclipse-SDK-3.0.2-win32\eclipse\plugins\org .eclipse.birt.report.viewer_1.0.0\birt\WEB-INF\lib\myJarFile .jar
access those POJOs in report's open method like:
<snip>
count = 0;
cf = new Packages.gr.osmosis.report.data.ContactListFactory();
c = cf.createContactList();
</snip>
this scenario work fine too
Here now comes the troubles:
in both scenarios i get error messages when i change the code snip to
something lik
<snip>
importPackage(Packages.gr.osmosis.report.data);
count = 0;
cf = new ContactListFactory();
c = cf.createContactList();
</snip>
considering rhino documentation [2] i have try to use importClass instead of
importPackage but without success
here are the error messages:
1. using importPackage
There are errors on the report page:Error1:Invalid Javascript expression.
Source: DataSet:setScript.open, line: 0,
Expression:function_prefix_1121503320257();function
function_prefix_1121503320257(){importPackage(Packages.gr.os mosis.report.data)count
= 0;cf = new ContactListFactory();c = cf.createContactList();}Script engine
error: ReferenceError: "importPackage" is not defined.
2. using importClass
There are errors on the report page:Error1:Invalid Javascript expression.
Source: DataSet:setScript.open, line: 0,
Expression:function_prefix_1121503320258();function
function_prefix_1121503320258(){importClass(Packages.gr.osmo sis.report.data.ContactListFactory);count
= 0;cf = new ContactListFactory();c = cf.createContactList();}Script engine
error: ReferenceError: "importClass" is not defined.
I have to notice that the code snip exist into report's open method.
i will appreciate any comment about this. is some piece that i'm missing ?
regards
stavros
