Bug 139648 BIRT Resouce deployment issue - Wrong relative path generated.
- Set the BIRT Resource Path using Windows->Preference to E:\birt\birtResources - Copy base.rptlibrary, testlibrary.rptlibrary files to the above location. - Now the library explorer will show all the two libraries. - Create a report design and add the report items from the libraries. - Open the XMLSource view of the report design. The relative paths to the library are not correct. <list-property name="libraries"> <structure> <property name="fileName">../../birtResources/base.rptlibrary</property> <property name="namespace">base</property> </structure> <structure> <property name="fileName">../../birtResources/testlibrary.rptlibrary</property> <property name="namespace">testlibrary</property> </structure> </list-property>
