This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
Hi, I am using BlueJ to write this assignment and i just cann't compile. What I have done as following: Step 1: Create a new project "DaysOld" in BlueJ; Step 2: Copy the zip file "JavaRanchCommon" into "DaysOld" file; Step 3: in Windows Command Promopt write "set classpath=D:/DaysOld;D:/DaysOld/JavaRanchCommon.zip"; Step 4: write in "DaysOld" class: import com.javaranch.common.*; Step 5: Compile but it says "com.javaranch.common.* does not exist"; Could someone tell me why and the solution? Thanks so much!
Hi there, I've never used BlueJ, so hope this will work for you. Depending on which version of Windows you're using you need to set the directory where BlueJ stores the .java files in the CLASSPATH (windows98 has the list in autoexec.bat or config.sys (can't remember which, sorry) - I use c:\javaranch and that is in my CLASSPATH list as c:\javaranch; (don't forget the ; at the end of the name). Once you've set the classpath then restart the PC (not essential with XP, but good practice). Copy the JavaRanchCommon zip file into that directory. Have another go at compiling and the system should be able to find the .zip file from the import com.javaranch.common.*; in your DaysOld.java file. Good Luck. All the best, Kate!!
I was curious about this BlueJ tool so I installed it on my win98 system. It's free If you compile the code on a prompt window (i.e. without BlueJ), just follow the instuctions given by Kate, it should be fine. But when I used the BlueJ, it still didn't work even with CLASSPATH set in the autoexec.bat (for win98). If you're using win2000, you set it on the Environment Variables. Then I realized you must use BlueJ-->Options-->Preferences-->Libraries and Add the path where your *.zip is stored. After that, exit and relaunch BlueJ to take effect.

Well done Joyce!
Charles, I've noticed that you haven't posted anything on the Assignment Log - have you signed up to the CattleDrive?
All the best, Kate!! [ July 15, 2004: Message edited by: Kate Head ]
Does the assignment log give an accurate picture of how many people are on the cattle Drive or are there many who don't post on it ?
Depends on what you mean by accurate
There might be people who don't post to the assignment log, but probably not many. So I think the log gives a fairly good (general) picture of how busy things are.
Then there are all the folks who are theoretically "on the drive", but just aren't very active at present. wink, wink (There's a *lot* of us that fall into that category, alas. )

Would it be right to assume then , if XML assignments come on line, the Nitpickers might be very busy !!!

I bet they are. Just imagine the number of students (graduated, active or inactive) in Cattle Drive. This's a time-consuming and highly committed voluntary job, no doubt. The nitpickers should be highly commended for the contribution to the JavaRanch.
