struts.taglib.tiles.InsertTag error during runtime

hwmeng Feb 26, 2003 8:48 PM

Hi all,
I'm having a problem during running the struts application on JBoss server. The application deployed successfully on JBoss server, but, most of the time the error will occur when i try to call the first page of the
application. It will only run smootly if i restart the JBoss server or perform a rebuild on the application again, or delete the temporary deploy folder in JBoss server serveral times.

Please help!!!

Server : jboss-3.0.4_tomcat-4.0.6 /
jboss-3.0.4_tomcat-4.1.12 /
jboss-3.0.4
Struts : 1.1 rc 1
jdk : j2sdk1.4.1
j2ee : j2sdkee1.3.1
O/S : window 2000

It might be helpful if you actually post where this error is occuring in your JSP/Tiles template and a copy of said JSP/Tile file.

cheers
