WebApps Getting Unsupported major.minor version 52.0 (unable to load class contexts.GXBasicContext)

  • 1.  WebApps Getting Unsupported major.minor version 52.0 (unable to load class contexts.GXBasicContext)

    Posted Fri May 15, 2015 05:34 PM

    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)

    org.apache.jasper.servlet.JspServlet.service(JspServlet.java:259)
    javax.servlet.http.HttpServlet.service(HttpServlet.java:729)

    root cause

    javax.servlet.http.HttpServlet.service(HttpServlet.java:729)

    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.
