问题：WebLogic启动时报UnknownHostException，具体是在启动MedRec域的时候出现的。想想以前修改过计算机名称，因此觉得可能和这相关。
解决方法是在C:\WINDOWS\system32\drivers\etc\hosts文件中添加相关的映射信息：

问题：WebLogic9.2设置预编译，在weblogic.xml文件中配置：
    <jsp-descriptor>
        <keepgenerated>true</keepgenerated>
        <package-prefix>jsp_servlet</package-prefix>
        <page-check-seconds>1</page-check-seconds>
        <precompile>false</precompile>
        <precompile-continue>true</precompile-continue>
        <verbose>true</verbose>
        <working-dir>D:\Project\logs\jsp_temp</working-dir>
        <print-nulls>true</print-nulls>
        <backward-compatible>true</backward-compatible>
        <encoding>GBK</encoding>
        <exact-mapping>true</exact-mapping>
        <default-file-name>true</default-file-name>

问题：修改了Session Bean某个方法（readByIdAndName）的参数，导致部署不成功，WebLogic版本为9.2。错误信息储如下列所示：
[EJB:011006]Unable to bind a cluster-aware stateless session EJBObject to the name: EARejb\FinanceUserManageSes_EO. Please ensure that the jndi-name in the weblogic-ejb-jar.xml is correct. Caused by: java.rmi.UnexpectedException: Failed to parse descriptor file; nested exception is:
    java.rmi.server.ExportException: Failed to export class …… problem with rmi descriptor signature readByIdAndName(Ljava.lang.String;Ljava.lang.String;) 解决方案：清空WebLogic缓存，准确地说是清空EJBCompilerCache，在部署的Server下面，删除此目录即可。
