weblogic.appc命令在WebLogic Server 10.3.5.0中使用ANT腳本失敗

Question

我正在將應用程序從weblogic 8.1遷移到weblogic 10.3.5版本。 同時通過ant腳本構建應用程序;我得到以下錯誤： -

weblogic.appc.run：

[java] Usage: java weblogic.appc [options] <ear, jar, war or rar file or directory> 
[java] 
[java] where options include: 
[java] -help Print the standard usage message.

下面是其中我在它運行Ant腳本。

<java classname="weblogic.appc" failonerror="true" fork="true" maxmemory="512m"> 
    <arg value="-disableHotCodeGen"/> 
    <arg line="-verbose"/> 
    <arg line="${weblogic.arg.line.compiler}"/> 
    <arg line="-compilerclass com.sun.tools.javac.Main"/> 
    <arg line="${weblogic.appc.options}"/> 
    <arg value="${compile.dir}/${ejb.domain}-ejbc.jar"/> 
    <arg value="${project.dir}/src/java"/> 
    <arg value="${compile.dir}/ejb/${ejb.domain}"/> 
    <classpath> 
    <path refid="weblogic.classpath"/> 
    <path refid="project.classpath"/> 
    <fileset dir="${java.home}/../lib" includes="tools.jar"/> 
    </classpath> 
</java> 

即使我不能夠找到java.lang.NoClassDefFoundError：weblogic的/ J2EE/J2EELogger。哪個jar支持這個？另外我已經正確設置了PATH和CLASSPATH。

讓我知道是否需要更多信息從我身邊。

總之，確保您的weblogic.classpath變量中有/wlserver_10.3/server/lib/weblogic.jar。

未加載的類是從/modules/com.oracle.core.weblogic.msgcat_1.1.0.0.jar。這應該通過/wlserver_10.3/server/lib/weblogic.jar中的MANIFEST.MF文件導入。假設您的weblogic.classpath中有weblogic.jar，則應加載類weblogic.j2ee.J2EELogger。

weblogic.jar加載/modules/features/weblogic.server.modules_10.3.5.0.jar然後通過它自己的MANIFEST.MF加載/modules/com.oracle.core.weblogic.msgcat_1.1.0.0.jar。

您的螞蟻配置中還有多個<arg line="">標籤。你需要修改這些。

<arg line="-disableHotCodeGen -verbose -compilerclass com.sun.tools.javac.Main ${weblogic.appc.options} ${compile.dir}/${ejb.domain}-ejbc.jar ${project.dir}/src/java ${compile.dir}/ejb/${ejb.domain}"> 

下面的另一個例子是我如何在我的ant版本中執行appc。

<target name="appc" depends="compile,jar"> 
    <java classname="weblogic.appc" fork="yes" jvm="${bea.java.home}/bin/java" maxmemory="1G" failonerror="true"> 
    <arg line="${archive.jarfile} -J-Xmx1g"/> 
    <classpath> 
     <pathelement path="${container.cp};${server.additional.classpath}"/> 
     <pathelement path="${archive.jarfile}"/> 
    </classpath> 
    </java> 
</target> 

此外，在-v開關運行螞蟻看到正在發出的命令，它應該幫助找出你的問題。
