快来帮帮我！看看我的我的问题！！jsp+javabean!!!!
我把bean.jsp放在tomact/.../wap/jsp/下，Lonnowbean.class放在tomact/../wap/WEB-INF/classes/Lonnow/下，且已经加入了classpath。而且我的bean本身没问题的，编译通过了的！！但是编译bean.jsp出错???/错误是：

aryTemp[]=lonnowbean.getLonnowInfo();
An error occured between lines: 14 and 19 in the jsp file: /jsp/bean.jsp

double aryTemp[]=lonnowbean.getLonnowInfo();
改成double aryTemp[]=Lonnowbean.getLonnowInfo();
把那个l大写了!

你把包的名字改为小写得试试看。

據你的軟件而定吧.
我用的Weblogic
若打包為jar時放在Applications\DefaultWebApp\WEB-INF\lib之下,若為字節碼文件*.class則應放在 \WEB-INF\CLASSES之下,這是我的應用中的配置,希望你作為參考..
