使用myeclipse建立的birt 報表檔案放在eclipse環境運作

          發現網上使用birt開發的人不是非常多，碰上問題很難解決，本人也是多次嘗試後擷取的結果(部分參考網上結論)， 本人birt序列文章屬于個人在研究學習使用birt過程中的筆記，純屬個人記錄。

           将使用myeclipse建立的報表放在eclipse環境下運作，在通路報表的時候報如下錯:

嚴重: Unable to determine the default workspace location.  Check your OSGi-less platform configuration of the plugin or datatools workspace path.

  找到報表檔案中，一下部分(資料庫不同詳細内容可能也會存在差别):

<ex-property>
                    <name>org.eclipse.datatools.connectivity.driverDefinitionID</name>
                    <value>DriverDefn.org.eclipse.datatools.enablement.oracle.10.driverTemplate.Oracle Thin Driver</value>
                </ex-property>
           

将這個節點内容注釋問題解決.
