问题描述
一客户案例，新安装完Agile 9.3.1.2， Weblogic 10.3.6， 服务能启动， WebClient能登录正常使用。而用户却无法登录JavaClient，JavaClient输入用户名后只显示蓝色背景，如下图。
启用Java Console后，出现如下ClassNotFoundException异常。

分析
一个标准的JavaClient部署之后，在WAR包中会引入weblogic client的相关class作为RMI调用。在weblogic/workarea/spi/的包中，只需要如下这两个类即可。错误中提及的WorkContextEntryImpl是不需要的。可以通过解压开agileDomain\applications\application.ear\JavaClient.war\wls\lib\appserver_wls.jar就可以查看。WorkContextAccessController.class
WorkContextMapInterceptor.class
Google该类也无从查起。进一步分析从Agile server日志看。注意到日志中从没有见过的下述关于jrockit的警告。
CLASSPATH=/u02/weblogic/patch_wls1036/profiles/default/sys_manifest_classpath/weblogic_patch.jar:/u02/weblogic/patch_ocp371/profiles/default/sys_manifest_classpath/weblogic_patch.jar:/u01/jrockit/jrockit-jdk1.6.0_24/lib/tools.jar:/u02/weblogic/wlserver_10.3/server/lib/weblogic_sp.jar:/u02/weblogic/wlserver_10.3/server/lib/weblogic.jar:/u02/weblogic/modules/features/weblogic.server.modules_10.3.6.0.jar:/u02/weblogic/wlserver_10.3/server/lib/webservices.jar:/u02/weblogic/modules/org.apache.ant_1.7.1/lib/ant-all.jar:/u02/weblogic/modules/net.sf.antcontrib_1.1.0.0_1-0b2/lib/ant-contrib.jar: PATH=/u02/weblogic/wlserver_10.3/server/bin:/u02/weblogic/modules/org.apache.ant_1.7.1/bin:/u01/jrockit/jrockit-jdk1.6.0_24/jre/bin:/u01/jrockit/jrockit-jdk1.6.0_24/bin:/usr/kerberos/bin:/usr/bin:/bin:/home/y201189/bin Your environment has been set.

MaxPermSize之类的JVM参数都是给SUN JDK用的，并非jrockit。在看CLASSPATH中也出现了jrockit的引用。
/u01/jrockit/jrockit-jdk1.6.0_24/lib/tools.jar
结论
用户错误地使用了jrocket作为启动Weblogic的JVM。对于APP所使用的JDK，Oracle有很明确的说明。
For WebLogic Server, only JDK 6 certified. For Linux, Solaris and Windows, only Sun JDK is certified. For AIX, only IBM JDK is certified. For HP-UX, only HP JDK is certified.
