[求助]与ORACLE连接问题？？

到oracle目录下考class1.zip文件

解决方案 »

  1.   

    在C:\oracle\ora90\jdbc\lib下没有你说的文件，但有classes12.zip，classes111.zip这两个文件，还有把这两个文件拷到哪里，是不是WEB-INF目录下面？？
      

  2.   

    我把classes111.zip放在root\WEB-INF\lib目录下，但是还是错误：type Exception reportmessage description The server encountered an internal error () that prevented it from fulfilling this request.exception javax.servlet.ServletException: Io ??: Connection refused(DESCRIPTION=(TMP=)(VSNNUM=150999297)(ERR=12505)(ERROR_STACK=(ERROR=(CODE=12505)(EMFI=4))))

    把classes12.zip，classes12.jar放在J2sdk1.4.2（看你自己的安装路径）的“lib”目录下，并设置“classpath”环境变量如下（参考）：
    .;d:\j2sdk1.4.2\lib\classes12.zip;D:\j2sdk1.4.2;d:\j2sdk1.4.2\lib\jxl.jar;d:\j2sdk1.4.2\lib
