OK, quick question... is <%= path %> ***itself*** null, or it simply being ---interpreted--- by Tomcat as null in the context of a tag attribute?
An easy way to check is to stick a copy somewhere inside a html comment adjacent to the tag where you're using it so you can launch the page and see for sure. For example... <!-- VALUE of path = '<%= path %>' --> ... inc="<%= path %>/jsp/dd/inc" ... if <%= path %> is itself null and is itself supposed to be set by another tag either wrapping it or coming earlier in the page, it's probably a problem with that tag's TEI file. On the other hand, if <%= path %> is non-null, check the tag's .tld file and make sure that the "inc" attribute has <rtexprvalue>true</rtexprvalue> "rtexprvalue" tells the compiler whether it can save time and hardcode the current value of <%= path %> at ***compile time***, or whether it needs to stop and fetch the current value of <%= path %> at ---runtime---. If rtexprvalue is false, it's using path's value at compile time... which more likely than not, is null. ----- Original Message ----- From: "Sundar Chakravarthy" <[EMAIL PROTECTED]> To: "Tomcat Users List" <[EMAIL PROTECTED]> Sent: Wednesday, September 25, 2002 1:23 PM Subject: Setting Tag Attribute Value Hi, I am on Tomcat 4.0.x , jdk1.4,win2K. When I try to set a tag attribute value using a jsp script varaible like below , inc= "<%= path %>/jsp/dd/inc/" the value of path shows up as null . Why ?
