problem of Null String

[dudoes]

I use Jboss3.0.1RC1/Tomcat4.0.4£¬I have got a strange problem:

System display "null" on page When a String gotten from DB is empty.

I hate "null", I can accept a empty String, "",etc.,rathen than a string whose content is "null".

Weblogic6.1 have not the same problem.

How can i config System to return a empty String instead of a "null" String? because it destoy my page.

Must I check every String if it is empty and convert it to a empty String by myself,not to a "null" String automatically by system?


I need your help.


thanks

eh? If your String is null, then it will display as null, if it is empty string it will display as empty string. I don't think jboss has too much to do with this

Yeh,

if the String is empty with nothing it display "null", but i hope it display ""(a String with "",not a String "null").

Weblogic6.1 has not this problem,Maybe Weblogic have handled the empty String to a "" String before sending to page.
