Tips

General Tips for Using HJV Administration

• Use a web browser to verify all URLs specified in /var/dhcp/dhcptab and in the JavaOS properties text file.

• Run snoop(1M) and watch the packets to and from the NC.

• Early access versions of Views improperly saved properties into ~/.jdt.

• See the README files in /opt/SUNWjdt/doc for each component.

• Refer to the following Solaris man pages: dhcp(4), dhcp_network(4), dhcpconfig(1M), dhcptab(4), dhtadm(4), pntadm(4), in.dhcpd(1M), snoop(1M)

• To update the "About" button, you must edit the lib/html/welcome/welcomeAbout.html file.

• To change the alias associated with the "Feedback" button, you must update the selector.props property for each group configuration.

CalendarView

• CalendarView works best with the Common Desktop Environment (CDE) calendar server. The feature of storing mail messages with appointments is available only for calendars in the data version 4 format. This format is supported by the CDE calendar server. The OpenWindows^TM calendar server does not support the data version 4 format.

• To find out whether the CDE calendar server is running on a particular machine, as superuser, type:

  # /usr/dt/bin/sdtcm_admin -l -h name-of-machine-to-check

  If the sdtcm_admin command returns a list of calendar names, the CDE calendar server is running on that machine. Otherwise, the command returns the following message:

  # /usr/dt/bin/sdtcm_admin: Could not list calendars because: Service is unavailable.

  The CDE calendar server is available in the SUNWdtdmn package.

• When an appointment is scheduled through MailView, the mail message containing the appointment is saved in the login user's calendar mailbox and a reference to the saved mail message is stored with the appointment. This feature is not available for calendars in the OpenWindows calendar format, data version 3 or less. This is a limitation of the data version 3 (or less) format.

You can use the /usr/dt/bin/sdtcm_convert calendar conversion utility to convert data from version 3 calendars to data version 4 format. Refer to the sdtcm_convert man page for details.

• The Additional Permissions list within the Properties dialog may contain login IDs instead of complete names (for example, joes may be displayed instead of Joe Smith). This can occur if the user's calendar is in the OpenWindows data format or if the entry was added using calendar clients other than CalendarView. If the calendar is in the OpenWindows data format, use the /usr/dt/bin/sdtcm_convert utility to convert it to data version 4 format. Refer to the sdtcm_convert man page. Otherwise, use only CalendarView to add editors.

• For editable calendars, clicking within an empty time slot creates a new 1-hour appointment in that time slot. There may be a significant delay in refreshing the view. If you did not intend to create a new appointment, delete it by clicking the Delete button in the CalendarView detail area.

• To demonstrate automatic update, you need two calendar clients (two CalendarView clients or CalendarView and dtcm).

NameView

• It may be useful to capture output from the Namesvc proxy to a file. This can be enabled by editing /opt/SUNWjdt/cgi-bin/namesvc. Comment the line:

  ---

  # $JAVA_HOME/bin/java sunw.jdt.dex.server.Namesvc

  ---

And uncomment the line:

# $JAVA_HOME/bin/java sunw.jdt.dex.server.Namesvc | tee /tmp dex.last

If you perform a search and this file doesn't get created or updated, then the httpd server is having problems launching the cgi-bin script. If the output in the file indicates some type of error:

---

Content-type: text/plain
<DBError>:6

---

then the database probably couldn't be found or the permissions on the file are not set correctly. Make sure the database files have read access for world.

• If you have enabled capturing output to /tmp/dex.last and this file isn't being updated, then check the httpd server error log file. This may indicate that there was some sort of cgi-bin error. The server may not be configured to run cgi scripts or might not be able to find the namesvc script.

• Make sure the database files you have created have read access set for world (chmod 664).

• The 1.1 back end is not compatible with 1.0 clients. If you need to support both 1.1 and 1.0 clients, you have several choices. The easiest solution is to install the 1.1 back end on a different server than the 1.0 back end. In this configuration you simply follow the steps that have already been outlined above. If you want to support 1.1 and 1.0 clients from the same server, follow these instructions:

  1. Install 1.1 on the server, but do not install it on top of your 1.0 installation. Put 1.1 under /opt/SUNWjdt1.1 or something similar.

  2. In your web server cgi-bin directory create a symbolic link from webserver/cgi-bin/jdt1.1 to /opt/SUNWjdtd1.1/cgi-bin.

  3. Edit the namesvc file in /opt/SUNWjdtd1.1/cgi-bin. Change the JDT_HOME environment variable from /opt/SUNWjdt to /opt/SUNWjdt1.1.

  4. Edit /opt/SUNWjdt1.1/lib/props/standard/nameview.props. Change the value of the dex.db.cgi.proxy property to /cgi-bin/jdt1.1/namesvc.2.0.

  5. Edit /opt/SUNWjdt1.1/lib/props/namesvc.props to point to your database.

Enable Error Message Logging

This release of HotJava Views has an error message logging capability that is used most extensively by NameView. If you want to enable this capability, use the following procedure on the system running your web server.

1. Assuming you have installed HotJava Views in /opt/SUNWjdt, create a symbolic link called jdt from within your httpd server's cgi-bin directory (this location varies among servers) to /opt/SUNWjdt/cgi-bin.

   For example, if you are running the Apache server, you can use the following commands:

   ---

   # pwd
   # /opt/WWW/Apache/httpd/cgi-bin Your httpd server's cgi-bin dir
   # ln -s /opt/SUNWjdt/cgi-bin ./jdt
   # ls jdt
   # getidsvc.2.0   jdtlogsvc  namesvc.2.0
   

   ---

2. Some web servers require that you explicitly turn on cgi-bin support before cgi-bin scripts can be executed. Refer to your httpd server's documentation to determine your server's requirements.

3. Edit the /etc/syslog.conf file and add the following line:

   ---

   # local0.info		/var/opt/SUNWjdt/jdt.log
   

   ---

   Make sure that you use tabs, not spaces, between the values.

4. Create /var/opt/SUNWjdt/jdt.log and modify its permissions:

   ---

   # mkdir /var/opt/SUNWjdt
   # touch /var/opt/SUNWjdt/jdt.log
   # chmod 666 /var/opt/SUNWjdt/jdt.log
   

   ---

5. Restart the syslog daemon:

   ---

   # kill -HUP `cat /etc/syslog.pid
   

   ---

   HotJava Views uses CGI to send error messages to the jdtlogsvc script on your web server. The jdtlogsvc script uses syslog to log the errors.
