[10/22/99}
Simplified procedure for moving from one machine to another
We finally figured out (I think) why some people were having trouble moving projects to different machines. Here are some simplified instructions:
1. Make an appropriate temporary directory for where you are working:
  - Business Building Teaching Lab C:\savework\YourName\jws
  - Student Computing Facilities C:\MyFiles\YoueName\jws
  - Tutoring in 3.02.04SB C:\Temp\Savework\YourName\jws
2. Be sure that all of the .java files you need are actually in your project directory of your floppy before coming.
3. Copy the entire project directory from your floppy to the appropriate location on the machine.
4. Add the project to your current portfolio as follows:
  - Select Add->Project on the Project menu
  - When the menu comes up be sure that you Add reference rather than copy project
  - Use browse to find the .prj file of the project to add.
  - DO NOT PRESS OPEN for the .prj. Instead DOUBLE CLICK on the project name.
You should be set.
[10/20/99]Exception-main thread not found error
If you program builds successfully, but you when you try to run the program, you get "exception - main thread not found" or a similar error, it is because the Java virtual machine doesn't know where the main program is.
This sometimes comes up when your main program name is different from the project name and/or the project directory.
The simple fix is to set the Main Class Name. Under the Project menu item select the Properties option. Instead of select the Class Path, select the Run tab and simple set the Main Class Name to the name of your main program (without the .java).
1. Make an appropriate temporary directory for where you are working:
  - Business Building Teaching Lab C:\savework\YourName\jws
  - Student Computing Facilities C:\MyFiles\YoueName\jws
  - Tutoring in 3.02.04SB C:\Temp\Savework\YourName\jws
.... rest coming
[10/4/99] My mouse blurs when I use JWS with Windows 98
I solved the problem I was having with my mouse in JWS on my home system. Windows 95 and 98 allow you to have all kinds of fancy mouse pointers. I was using a 3D mouse pointers with "tails" that followed the pointer every time it moved. Apparently, JWS couldn't handle that kind of graphic mouse pointer, because when I went into my control pannel and set the mouse pointer back to the Windows standard default, JWS worked beautifully. If anyone else was having similar problems, this might be the solution for them as well. Another thing that might help them is trying a higher screen resolution. A friend of mine said he had a problem with his mouse at first as well and the higher resolution fixed it. For me, though, higher screen resolution didn't help at all. It was just the mouse pointer settings.
[9/27/99] What are the permanent MII tutoring hours?
The hours the same as given below for the week of 9/20. They can also be found at http://ringer.cs.utsa.edu/~rcastane/MII/tutor.html.
[9/22/99] Student computing facility hours
- Multidisciplinary Studies Facility:
  - M-Th 7 am to midnight
  - F 7 am to 10 pm
  - Saturday 10 am to 8 pm
  - Sunday 2 pm to midnight
- Business Building:
  - M-Th 7 am to midnight
  - F 7 am to 10 pm
  - Closed weekends
[9/20/99] If you brought it in, pack it out
We would like you to follow the Backpacker's Creed: If you brought it in, pack it out.
Please follow this procedure when you are about to leave an on-campus machine:
1. Unhook all of your personal portfolios from Java WorkShop (Remove Portfolio on the Edit menu)
2. Use the file explorer on your machine to copy your jws directory to a floppy.
3. Use the file explorer remove the directory (YourName/jws). (Drag it to the recyle bin.)

Remember the paths are:

Business Building Teaching Lab C:\savework\YourName\jws
Student Computing Facilities C:\MyFiles\YoueName\jws
Tutoring in 3.02.04SB C:\Temp\Savework\YourName\jws

Thanks for you cooperating in maintaining a "clean" computing environment.

[9/20/99] My email scrolls off the screen If you have trouble with mail scrolling off of the screen, telnet to pandora using the RUN item on the START menu. When asked what program to run, type

   telnet pandora.cs.utsa.edu

You should get a window that is better behaved. Also, remember we are NOT using runner, we are using pandora. The telnet runner icon in the student labs takes you to the wrong place.

[9/20/99] How do I print documentation for Java WorkShop?
All of the Java WorkShop documentation and tutorial files are in html format. The only hard part is finding out where Java WorkShop was installed. The standard place is in:

\Program Files\Java-WorkShop3.0.3\Java-Workshop3.0\lib\html\help\jws\

on the drive Java WorkShop was installed on. There are many subdirectories under here. A tutorial can be found in start\overview.html under the above directory. You can use a web browser to get at it.

[9/17/99] Permanent supplemental instruction hours
Rehan's schedule has been finalized. He will be available

         Tuesday 4 to 5   
         Wednesday 4 to 5
         Friday 2 to 3

For the first few weeks he will be in 3.02.04SB because there are some NT machines that we can use during tutoring.

Supplemental instruction is formalized tutoring. Rehan comes to the lecture, takes notes and does the course assignments. He is prepared to help you with specific course content. In addition to his three tutoring sessions a week, he will be giving about 8 formal study sessions for exam preparation during the semester.

[9/17/99]How do I forward my mail to another account from my CS account?

Telnet into pandora:

     telnet pandora.cs.utsa.edu

log into your account. Type

      vi .forward

This gets you into vi to create the .forward file Type a lower case i to get into input mode. Type your email address at the beginning of the first line of the file. Hit the escape key to get out of input mode. Type

    :wq!

to exit vi. Log out. You should be set.

[9/16/99] CLASSPATH for simpleIO
The simpleIO package has been installed in the student computing facilities and in the teaching labs.

In the student computing facilities, add the CLASSPATH value of j:\krobbins\1711 to your project under the Properties menu on Java WorkShop.

In the teaching labs, the CLASSPATH is:

x:\1711

assuming that you have mapped \\coblab2\classes to the x: drive.

[9/15/99] Supplemental Instruction - Week of 9/13
Rehan Akbani is the supplemental instructor for CS 1713/CS 1711. This Thursday 9/16/99 and Friday 9/16/99 from 2 pm to 3 pm he will be holding a supplemental instruction session in room 3.02.04 SB (the Computer Systems Lab). We have set up a few machines so that you can sit down and get some help. He will be concentrating specifically on Lab 2 and general problems with using Java WorkShop. IF YOU ARE HAVING TROUBLE GETTING LAB 2 done or feel confused about it, please consider attending one of these sessions.

[9/15/99]Microsoft Software offer
MICROSOFT SOFTWARE SALES MOVE TO UC GAMEROOM The sale of Microsoft software to UTSA students, faculty and staff under the Campus Enterprise Agreement between Microsoft and the UT System, formerly done through the Computer Store, is now being done at the University Center gameroom. The gameroom is located behind the fountain in the UC courtyard. Hours of operation are 8:30 am - 12:30 pm and 2 - 4:30 pm. Monday - Friday. The telephone number is 458-4733. For more information, click on: http://www.utsa.edu/students/index.html and go to Software Sales under Student Information."

[9/9/99]Running in the student computing facilities:
Java WorkShop has been installed in all of the student computing facilities. Look in the directory called Development Tools

You will need to follow the same procedure as in the teaching labs. The directory that you should save to while you are working is:

c:\MyFiles\YourName\jws

You will need to copy to a floppy at the end of your session and remove this directory from C:

On the machines: Look for machines that say Dell GX1 Optiplex. These machines are 400 Mhz machines with plenty of memory. In the MS Computing Facility these are machines 1 through 70. The Business Computing Facility and DownTown also have some higher power machines but not as many. You want to avoid sitting at one of the older machines with only 32 Meg of memory. That is barely enough to run the operating system and is glacial when you try to run something else.
