UnsupportedClassVersionError with Tomcat 5.0.28

[Sunitha Mudidani]

Hi all,

Iam using tomcat 5.0.28 version, jdk 1.4.2_12,eclipse 3.2 ,struts 1.2.9

I have installed the sysdeo plugin and tomcat is starting properly.But when i execute a simple struts project (struts blank.war)

I am getting the following error . the same error is obtained when i run by starting tomcat outside eclipse.

  javax.servlet.ServletException: org/apache/jsp/index_jsp (Unsupported major.minor version 49.0)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:244)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

When I load struts-blank.war directly into webapps dir and exceute I am able to run properly. What cud be the problem?

Thanks

it means that JDK version that used to build the struts library or your own classes is a newer version that JDK that is used by tomcat.

so :
-Update tomcat JDK
-build your own source code and/or Struts source code using JDK version that your tomcat is using.
