由于SessionLoaderExceptions导致Ant链接验证失败

Question

我正在尝试将toplink的会话导出与我的生成过程（Apache Ant）集成。我已经从这里的例子工作： http://download.oracle.com/docs/cd/E14571_01/web.1111/b32441/mw.htm

我的Ant目标初始化和会话验证目标如下：

<!-- ============ 
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> 

我从蚂蚁以下错误：

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: 

当我在蚂蚁中打开详细模式时，我可以看到更多的错误细节：

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) 

上面显示的3个错误对应于session.xml文件中同一级别的3个标记。我使用从工作台生成的session.xml文件测试了此验证过程，但也失败了。由于它的NoSuchMethodException它看起来像我的蚂蚁进程没有找到oracle.toplink.tools.sessionconfiguration.XMLLoader类，但它是在类路径中的toplink.jar。

任何帮助表示赞赏

完全基于文件的名称似乎您试图加载的映射元数据文件（又名project.xml中）作为会话元数据文件。 XMLLoader仅用于加载会话配置文件（又名“sessions.xml”）。
