由於SessionLoaderExceptions導致Ant鏈接驗證失敗

Question

我正在嘗試將toplink的會話導出與我的生成過程（Apache Ant）集成。我已經從這裏的例子工作： http://download.oracle.com/docs/cd/E14571_01/web.1111/b32441/mw.htm

我的Ant目標初始化和會話驗證目標如下：

<!-- ============ 
init Target 
============== --> 
<target name="init"> 

<property name = "toplink.home" value = "C:/APPS/OC4J/toplink"/> 
<property name = "oracle.home" value = "C:/APPS/OC4J"/> 
<property name = "toplink.log.dir" value = "${basedir}/../toplinklogs"/> 

<property name = "toplink.mwp.dir" value = "${basedir}/../java/mwb"/> 
<property name = "toplink.sessions.dir" value = "${basedir}/config"/> 
<property name = " myProject.classes" value = "${basedir}/../java/classes "/> 

<path id = "database.classpath"> 
<pathelement path = "${oracle.home}/lib/dms.jar"/> 
</path> 

<path id = "toplink.classpath"> 
<pathelement path = "${toplink.home}/jlib/toplink.jar"/> 
<pathelement path = "${oracle.home}/j2ee/home/lib/ejb.jar"/> 
<pathelement path = "${oracle.home}/lib/xmlparserv2.jar"/> 
<pathelement path = "${toplink.home}/jlib/antlr.jar"/> 
</path> 
<path id = "mw.classpath"> 
<pathelement path = "${toplink.home}/jlib/tlmwcore.jar"/> 
<pathelement path = "${toplink.home}/jlib/toplinkmw.jar"/> 
</path> 
<path id = "mwplatforms.classpath"> 
<pathelement path = "${toplink.home}/config"/> 
</path> 

<typedef file = "${basedir}/toplink-ant-lib.xml" classpathref = "mw.classpath" uri = "toplinklib" /> 
</target> 

<!-- ====================== 
validate session Target 
======================= --> 
<target name="validate.session" depends="export.project" if="export-completed"> 
<toplink:session.validate 
sessionsfile = "${basedir}/../java/src/aquila/administrator/accounting/config/toplink/AccountingMapping.xml" 
sessionname = "AccountingMapping" 
property = "session-valid" 
classpathref = "toplink.classpath" 
classpath = "${myProject.classes}" > 

<toplink:classpath refid = "mw.classpath" /> 
<toplink:classpath refid = "database.classpath" /> 

<toplink:loginspec refid = "loginSpec" /> 
</toplink:session.validate> 
</target> 

我從螞蟻以下錯誤：

validate.session: 
[toplink:session.validate] An error occured while validating project: 
[toplink:session.validate] Exception Description: Several [3] SessionLoaderExceptions were thrown: 

BUILD FAILED 
C:\Eclipse\Administrator\ant\example.xml:105: An error occured while validating project: 
Exception Description: Several [3] SessionLoaderExceptions were thrown: 

當我在螞蟻中打開詳細模式時，我可以看到更多的錯誤細節：

Local Exception Stack: 
Exception [TOPLINK-9001] (Oracle TopLink - 10g Release 3 (10.1.3.0.0) (Build 060118)): oracle.toplink.exceptions.SessionLoaderException 
Exception Description: Unknown tag name: [toplink:login] in XML node: [toplink:object-persistence]. 
Internal Exception: java.lang.NoSuchMethodException: oracle.toplink.tools.sessionconfiguration.XMLLoader.process_toplink:login_Tag(org.w3c.dom.Node, oracle.toplink.tools.sessionconfiguration.XMLLoader$ObjectHolder) 

Local Exception Stack: 
Exception [TOPLINK-9001] (Oracle TopLink - 10g Release 3 (10.1.3.0.0) (Build 060118)): oracle.toplink.exceptions.SessionLoaderException 
Exception Description: Unknown tag name: [opm:class-mapping-descriptors] in XML node: [toplink:object-persistence]. 
Internal Exception: java.lang.NoSuchMethodException: oracle.toplink.tools.sessionconfiguration.XMLLoader.process_opm:class_mapping_descriptors_Tag(org.w3c.dom.Node, oracle.toplink.tools.sessionconfiguration.XMLLoader$ObjectHolder) 

Local Exception Stack: 
Exception [TOPLINK-9001] (Oracle TopLink - 10g Release 3 (10.1.3.0.0) (Build 060118)): oracle.toplink.exceptions.SessionLoaderException 
Exception Description: Unknown tag name: [opm:name] in XML node: [toplink:object-persistence]. 
Internal Exception: java.lang.NoSuchMethodException: oracle.toplink.tools.sessionconfiguration.XMLLoader.process_opm:name_Tag(org.w3c.dom.Node, oracle.toplink.tools.sessionconfiguration.XMLLoader$ObjectHolder) 

上面顯示的3個錯誤對應於session.xml文件中同一級別的3個標記。我使用從工作臺生成的session.xml文件測試了此驗證過程，但也失敗了。由於它的NoSuchMethodException它看起來像我的螞蟻進程沒有找到oracle.toplink.tools.sessionconfiguration.XMLLoader類，但它是在類路徑中的toplink.jar。

任何幫助表示讚賞

完全基於文件的名稱似乎您試圖加載的映射元數據文件（又名project.xml中）作爲會話元數據文件。 XMLLoader僅用於加載會話配置文件（又名「sessions.xml」）。
