Summary: Unable to launch DrJava from jar file

Initial Comment:
I built DrJava from source and ran "ant jar" to build
the jar file.
The result is that the application is not running when
I launch it using
java -jar drjava.jar
However, I am able to launch it when I run the
following command
java edu.rice.cs.drjava.DrJava

I am using Linux and JSDK ver 1.4.1

I would like to run it from the jar file.

Summary: JavaDoc usage

Initial Comment:
After working with the JavaDoc interface for a bit, I 
realized that there are two distinct reasons for 
generating JavaDoc, and the current DrJava interface 
isn't quite right for both of them.  There are two stories:

1) User is working on a file and wants to see/proofread 
the JavaDoc generated from that one file.  The 
generated JavaDoc for this use would benefit from not 
having all the links to inherited information -- the user is 
essentially toggling between the JavaDoc and source for 
the class.  Itwould be best to have the JavaDoc appear 
in a simple window with no frames.  (BTW, this is a 
powerful teaching tool since it makes a strong 
distinction between the implementor's and client's view 
of a class.)

2) User wants to generate JavaDoc for the entire 
project, either for his/her personal use or to make it 
available to others.  This is best displayed in a standard 
JavaDoc framed viewer, with lists of classes to the left, 
an index at the top, etc.

I'm not sure if this really qualifies as a bug or as a 
feature request, so my apologies if it's posted in the 
wrong place.  However, it'd be great to think this 
through and refine the interface.

Thanks

Hal

Summary: JavaDoc generation somewhat clumsy

Initial Comment:
Finally got some time to try out the 7/1 beta.  This is 
great stuff (mostly).

The JavaDoc integration is a great addition, but it is a 
bit clumsy to use.  There are two things in particular 
that I hope can be tweaked easily enough:

1)  DrJava should have a sensible default for where to 
put the generated JavaDoc.  Right now, it pops up a 
dialog to select a directory, with a default directory that 
seems to be an almost random choice - meaning the 
generated docs could wind up "lost".

Best would be to just go ahead and create a "doc" 
directory in the top-level folder containing the DrJava 
project that's currently open.  There might be some 
reason to allow the user to change this as a per-project 
option, but beginners wanting to view their JavaDoc 
should be able to generate it and have something 
reasonable happen without having to navigate or 
configure anything. (BTW, "doc" is the directory BlueJ 
uses.  Doing the same might minimize some confusion if 
people switch between the two environments.)

2)  I generated JavaDoc for a tiny class and the viewer 
that popped up had a couple of frames with the 
following message in the large frame to the right: "the 
front page has been relocated.  Please see: frames 
version | non-frames version".  The "frames version" 
button is a complete mistake, since it produces a frame 
within the frame.  In any case, this shouldn't happen.

Configuration: WinXP Pro, Java 1.4.2, DrJava 20030701-
0203.

Thanks

Summary: Interactions "No Method" Error Message

Initial Comment:
When the current interactions pre-processor (as of
beta-20030701) cannot find a method Y in class X, it
prints this message:

Error: No 'Y' method in 'X'

However, this message can be misleading if the reason
the pre-processor cannot find the method is because of
the type of its arguments.  Take this simple
interaction, for example:

> System.exit();
Error: No 'exit' method in 'java.lang.System'

The pre-processor should check whether a method exists
with different arguments than given before printing
this message.  If a method or methods with this name is
found, a different error message should be produced,
highlighting the argument mismatch.  Perhaps the error
message could print the signatures of potentially
matching methods with the given name, up to a limit of
a few lines of output.

the mouse pointer in the interaction pane turns into a

terminate the program seems to be to reset interactions.

If I am watching a variable, and then modify the

the variable in the Watch pane isn't updated.  However,
the value of the variable within the running program is
correctly updated.  It appears to be totally
repeatable.  I tested this with a tiny program that
just set and returned an int value, so I won't bother
posting it here.

[DrJava] DrJava Beta Release

[Charles R. <cr...@ri...>]

  We have just released drjava-beta-20030701, a beta release in
preparation for the next stable release of DrJava.  This version contains
all of the improvements and bug fixes from the recent development
releases, written primarily by the students of Rice University's Comp 312
(Program Engineering) course.  Among many other changes, these new
features include support for using the Interactions Pane in the context of
a breakpoint in the debugger, support for generating Javadoc
documentation, support for generic types in the Interactions Pane, and
support for reading input from System.in.  A significant number of bugs
have also been fixed in recent releases.

  This beta release will serve as the basis for the next stable release of
DrJava, which will be available in about two weeks.  We encourage you to
download and extensively use this release, submitting any bugs that you
find.  We appreciate your help in making DrJava as stable as possible!

You can download the beta from our home page:
http://drjava.org

Thanks,
Charlie Reis

Summary: Show test names when testing

Initial Comment:
Story:
User clicks Test on a JUnit TestCase.  The Test Output
tab is displayed, with a message indicating which file
is being tested.  As each test method starts, the name
of the test is printed to the tab.  As each test method
completes, the result is either printed next to the
test name or the test name is colored green or red
according to the result.  When all the tests complete,
any errors (or the success message) are printed below
the list of test names.  (Optionally, the time taken
for each test could be displayed as well.)

Notes:
Almost all the information needed for this is already
passed into the listener.  We just have to display it
in the panel.  Care needs to be taken to associate the
right result with the right name, though, since the
events don't necessarily happen in order if the test is
fast.

Summary: No watch values for multiple nested classes

Initial Comment:
In the debugger, the user can watch variables and field
on the current class or its enclosing class.  However,
fields on enclosing classes beyond one level don't
work, such as:

class Foo {
  int x;
  class FooInner {
    class FooInnerInner {
      public void foo() {...}
    }
  }
}

While at a breakpoint in foo(), the watch table won't
see x.

This is because the watch logic only looks for this$0,
and not the correct field.  (In the case above, it
would be this.this$1.this$0.x.)  This will be
particularly hard to fix, since we don't know which
index to use for the first "this$N"...

Summary: Javadoc links don't work in Windows

Initial Comment:
Once the Javadoc browser has been displayed in Windows,
the user is unable to follow any links.  The links in
the files are relative, but the URL doesn't include the
base directory.

(eg. A link to Foo.html creates a URL to file:/Foo.html
instead of file:C:\dir\Foo.html.)

This could be an issue with HTMLDocuments in Windows,
since the HTMLDocument is supposed to have a notion of
a base directory.  We might just need to set it explicitly.

Initial Comment:
If you use different names for the same file, you can
open multiple copies of it in DrJava.  For example, the
following will all open as separate files:

/home/user/code/Foo.java
/home/user/code/./Foo.java
/home/user/code/dir/../Foo.java

This could result in strange behavior with inconsistent
copies of a file.

Besides the WindowsProgressBarUI, I also got the error 
from a WindowsToggleButtonUI.

Anyway, we should try to track this down at some 
point.  It's not essential--DrJava runs fine with plain old 
Metal, but this problem can also occur if jdk1.4.2 users 
try to run new apps with this look-and-feel from the 
interactions pane.

significantly improved Javadoc features (such as the ability to specify 
custom parameters in the Preferences window), re-enabled support for 
generic types in the Interactions Pane, and tool tips for each option in 
the Preferences.

   This will likely be the last development release before the upcoming 
beta release, so please download it and give it a try in your 
environment, letting us know if you encounter any bugs.  You can

Summary: DrJava Freezing After File Open

Initial Comment:
I try to open a file and after FileChooser is closed,
the application hangs.

Also, when the application is first launched, an error
message appears:

The interations window was terminated by a call to
System.exit(3)

Does this message have anything to do with the freezing
of the application.

I am running the code base on a linux machine using JDK
1.4.1.  I any updated this morning.

Summary: Cannot find javac.jar

Initial Comment:
I am unable to find the javac.jar file required for
JSR-14.  I went to Sun's website following the URL that
was given on the website to download the zip file. 
When I downloaded it, and unzipped, there was not jar
file labeled, javac.jar.  There are other jar files in
there, but unclear as to which one is the required one
for DrJava.

please advise.

Summary: Config Option Descriptions

Initial Comment:
Story:
A new user to DrJava is trying to set up his
preferences.  While browsing the various configuration
options, the user comes upon an option whose use is not
immediately apparent.  Confident that the DrJava
developers would provide him with help in this
situation, the new user hovers the mouse over the
option, and a tooltip pops up with a complete
description of the option.  The user is then able to
configure his DrJava more intelligently.

This would probably be fairly straightforward to
implement.  Each Option would have a method like
"getDescription()" to give detailed information as to
its function.  Each OptionComponent would then merely
have to call JComponent.setToolTipText() with the
description.

This information would probably be optional, so as to
save implementing it for particularly braindead
options.  If setDescription() is never called, no
tooltip would be displayed.

Summary: No compiler in JDK 1.3 since 20030613

Initial Comment:
I'm amazed this hasn't been discovered sooner (and I'm
partially to blame), but none of the recent development
releases from June 13th forward work in JDK 1.3 on any
platform.  DrJava complains that it can't find
tools.jar, even if the user specifies it.

This is almost certainly a problem with compilers.jar,
which was modified to support JSR-14 v2.0.  We need to
address this ASAP.

(I'm about to leave town for the weekend, so I'll look
at it with Neal on Monday.)

[DrJava] drjava-20030620-1754 / Update src

[Charles R. <cr...@ri...>]

   The drjava-20030620-1754 release is now available, which provides 
several bug fixes for classloading issues in the Interactions Pane, 
along with improved logic for watches in the debugger.

   This version also includes support for the Clover test coverage tool 
in DrJava's build process.  Run "ant clover" in either the drjava or 
util directories to generate a "clover" HTML directory next to your 
"src" directory.  The current clover reports are online at:
http://drjava.sf.net/clover/


   IMPORTANT:  Many changes have been made to the lib directory and 
build-common.xml, and there have been recent changes to the compiler 
adapter source trees.  To get these changes, run "cvs update -Pd" in 
your ~/drjava/src directory.  You will also need to put the new 
clover.jar from the "lib" directory on your classpath!

[DrJava] [ drjava-Bugs-757409 ] Marine Biology Case Study problems

Summary: Marine Biology Case Study problems

Initial Comment:
I am experiencing the following "show stopper" behavior
with the Advanced Placement Marine Biology Case Study,
with all recent versions of DrJava as well as the last
stable release, under JDK 1.4.1_03.

Here is my sample program:

class ExerciseSet1 {
  public static void main(String[] args) {
    BoundedEnv env = new BoundedEnv(20,20);
    
    Location loc1 = new Location(7,3);
    Location loc2 = new Location(7,4);
    Direction dir1 = env.getDirection(loc1,loc2);

  }
}

This code compiles just fine. When I try to run it in
the Interactions Pane by saying "java ExerciseSet1", I
get the error:

"Error: Undefined class 'ExerciseSet1'"

This error goes away if I comment out the last line of
my sample program, i.e. the one that runs the
getDirection method. The code also runs just fine if I
use different methods in the BoundedEnv class instead,
such as env.numCols(). The only difference that I can
see between these methods and getDirection is that the
getDirection method is not explicitly contained in the
BoundedEnv, but is instead inherited from the abstract
superclass SquareEnvironment.

I have my classpath in DrJava set up to include the two
jar files provided by the Marine Biology case study,
namely mbsgui.jar and mbsbb.jar. The code for
BoundedEnv is explictly provided, but SquareEnvironment
is provided as "black box" code and only its compiled
class file is provided in mbsbb.jar.

The above code runs just fine both from the command
line and within JCreator.

Could this be a problem with Dynamic Java?

The above code is a fragment of the very first program
that the students are asked to write within the case
study. 

I have included the zip file containing the Marine
Biology Case Study, which is also available for
download from the College Board.

Summary: Debugger unusually sluggish in new releases

Initial Comment:
I am trying to run the new development releases 
drjava-20030613-1720.jar and drjava-20030617-2059.jar 
on my office machine, which is a 733 MHz Windows 98 
machine running JDK 1.4.1_03. When I select Debugger, 
Debug Mode from the menu bar at the top, DrJava is slow 
about bringing up the debugger pane (15 seconds). 
Running a small program with a breakpoint on the second 
line seems to hang indefinitely.

The last stable release (drjava-stable-20030313.jar) is 
sluggish but useable: 1 second to start the debugger 
window, and 14 seconds to reach the breakpoint on the 
second line of my program.
