core tag compatiblity issue migrating from WAS5.1 to WAS6.0
Zones: Java Standard Tag Library (JSTL) & Server Tags, Java Server Pages (JSP), WebApplications
Hi Experts,

we have all our core tags uri as
<%@taglib uri="http://java.sun.com/jstl/core" prefix="c"%>
this somehow seems to not work for WAS6.0. we tried a few things and found that if we change the uri to following it works fine:
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
we dont want to go thru and change this in every jsp. also such a change will not be backword compatible. I am not sure if this is the only solution. I am sure i am missing something here.

suggestions and/or thoughts?

thanks
Sunil

>if we change the uri to following it works fine: <%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>  
If that is the case then you have the JSTL 1.1 jars in your classpath. If you don't want to change every page then you should remove 1.1 and put the 1.0 jars.    Now the question is; Do you want to use any 1.1 features ?    Personally I would change every page.

Hi rrz,

i agree with you. but i dont want to move to 1.1 and then not have my code work in was5.1. Also does WAS6.0 defaults to internal lib for jstl.jar. I am asking you this because we have a taglib-uri and location pointing to our 1.0 jstl but it doesnt seem like server is reading from there.

thanks

I only know Tomcat. I don't know anything about WAS.

I see your problem now.
>Also does WAS6.0 defaults to internal lib for jstl.jar. I am asking you this because we have a taglib-uri and location pointing to our 1.0 jstl  
JSTL doesn't use taglib-uri tag.  All that is necessary is to put the two jars into your classpath ( in Tomcat we just put them into Tomcat's lib directory).  No other configuration is required other than using the taglib directive on the page.     Are you able to switch to old jars ?  Or will the others that use the server be angry ?

One solution is that you can place the 1.0 jars so that they are found by the classloader before the 1.1 jars are found. In Tomat this is possible( but I haven't tested)  because the classloader looks in the web app's lib before it looks in Tomcat's lib.  I don't if this is possible in WAS.   I suggest you ask at
