Applinx 9.7 Designer

Apache Tomcat 5.5.30

java version 1.7.0_17

The above are components that come with Applinx 9.7.

I generated a web application and tried to run it from tomcat via http://localhost:8080/pipapx. I get the following error:

Stacktrace:
org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:489)

Can someone advise?

Thanks.

Looks like you have some mismatch in the Java versions you’re using to compile and run the project.
Without more information I would guess that the webapp was created and compiled using Java 8 in Eclipse while you use Java 1.7 to run the tomcat server.
