Root cause exception NoSuchMethodException for javax.servlet.jsp.PageContext.pushBody(Ljava/io/Writer(wink)

Symptoms:

While trying to access the very first page (right after installation, you get this exception

Cause

XPlanner must be running on a servlet 2.4 compatible container (Tomcat5.0+). Tomcat4.1 does not work.

Root cause NullPointerException in UseBeansTag.doEndTag

Symptoms:

While trying to access the very first page, you get this exception

Cause

  • If you are running 0.6.2, you may have specified your db connection settings directly in resource/xplanner.properties. A bug in 0.6.2 build system makes it only look in resource/xplanner-custom.properties. Specify your db connection settings in resource/xplanner-custom.properties instead.
  • Otherwise, check your connection settings. This exception indicates that xplanner could not create a connection.

    (I couldn't figure out how to edit this page. I hope leaving a comment instead is ok. Emailing xplanner-devel@lists.sourceforge.net also fails.)

    XPlanner fails to start.

    log4j:ERROR Could not create an Appender. Reported error follows.
    java.security.AccessControlException: access denied
    (java.io.FilePermission /xplannerActivity.log write)
    ...
    log4j:ERROR Could not parse url
    file:/var/lib/tomcat5.5/webapps/xplanner/WEB-INF/classes/log4j.xml.
    java.lang.NullPointerException

    Environment

    OS: debian etch (technically 2.6.18.8-domU-linode7)
    JAVA: 1.5.0_14-b03 however, I installed 1.4, #update-alternatives
    --config java, apt-get remove sun-j2re1.5, and then /usr/lib# ln -s
    j2sdk1.4-sun j2sdk1.5-sun
    when I type java -version I get 1.4, but for some reason when tomcat
    starts it cites 1.5. I've even restarted the machine. eit. is this
    the problem?
    TOMCAT: 5.5
    ARCH: i386
    XPLANNER: 07b7-war

    Symptoms:

    I downloaded the xplannar war zip and went through the steps of
    setting up the mysql database.

    The tomcat web manager starts without xplanner running, though the
    tomcat example apps are running. Click "start" fails:
    FAIL - Application at context path /xplanner could not be started

    catalina_2008-03-17.log msg is at the end of this email.

    Let me know if I need provide any more information. Any help you can
    provide would be GREATLY appreciated. I know this is more of a
    environment setup issue than xplanner bug but I've been trying to
    circumvent this obstacle for the past week.

    Thanks,
    Lucy.
