  • Class not found error deploying war file to tomcat 7

    This is hopefully a fairly simple problem of deployment settings.

    I have a war file that includes my app, plus the isomorphic directory and the WEB-INF files from SmartClient_v100p_2015-11-11_Pro. I deploy the war using the tomcat web management app. When I try to browse to the app jsp file I get
    org.apache.jasper.JasperException: javax.servlet.ServletException: javax.servlet.jsp.JspException: java.lang.ClassNotFoundException: com.isomorphic.sql.SQLDataSource

    There is of course a lot more to the error, but this feels like a class path problem. Being new to tomcat I don't know where to look for the relevant settings.

    The full error text:
    HTTP Status 500 - javax.servlet.ServletException: javax.servlet.jsp.JspException: java.lang.ClassNotFoundException: com.isomorphic.sql.SQLDataSource


    type Exception report
    message javax.servlet.ServletException: javax.servlet.jsp.JspException: java.lang.ClassNotFoundException: com.isomorphic.sql.SQLDataSource

    This doesn't look like a settings issue per se, just the lack of isomorphic_sql.jar or one of it's dependencies. See "javaModuleDependencies" in the SmartClient Reference.
