Synopsis: Missing Main Class File in PM causes debugger not to stop in 
init/main on load. 


Description: When creating a Project, if on the Create Project page under the 
Applet tab, you don't specify the "Main Class File" as something like 
"Bubbles.java", the debugger won't stop the applet as it brings it up. (Also 
see the "Main Class File" on the Edits Project Page under the Debug/Browse 
tab.) 



Also "Main Class File" is confusing? Should I type in the name of a "class" 
file (*.class) here? Or a "source" file (*.java) here? "Source File 
containing main/init" might be clearer. 


appletmanager 

Synopsis: click on project run while debugger is up, popup the "kill session" 
dialog 



Description: Click on project run button while the debugger is up, jde popup 
the "kill session" dialog. The dialog should not popped up. 

appletmanager 

Synopsis: Project Copy menu item enabled when no project selected 

Description: When there is no selected project, either because the portfolio 
is empty or because the user deselected the current project in the portfolio 
manager, the Project=>Copy menu item should be disabled. This is harder, but 
the Project=>Paste... menu item should be disabled when there is no project 
in the clipboard. 





appletmanager 

Synopsis: importing an empty portfolio doesn't clear the previous project 
attributes 



Description: To reproduce: 

�open an existing portfolio and project �import a portfolio that doesn't have 
any project in it �the toolbar now shows the new portfolio and no project 
�click on the 'Edit Project' icon �the folder tabs still show the old project 
attributes 





appletmanager 

Synopsis: applet with exit menu item will exit all of jws 



Description: I have an applet which opens an external window. There is a menu 
item on the window to exit, and when the user chooses OK, I call 
System.exit(0); 



This unfortunately exits the entire jde! 





appletmanager 

Synopsis: paste dialog needs to disable some fields 



Description: The Project FIle is read-only in the Paste dialog so the URL and 
File radio boxes and the file chooser button that apply to this textfield 
should be disabled. 





appletmanager 

Synopsis: project copy/paste doesn't creat new project build page correctly. 



Description: 





�select an applet project which have a source file �copy and paste the 
project select created by "copy" select "No" to include source apply the 
paste �bring up project->edit->build page the build page say that the project 
have a source file which is incorrect 





appletmanager 

Synopsis: in edit project, need to use FileOrUrlPanel on some TextFields 



Description: the following Project Edit textfields should allow the user to 
enter a file or URL via FileOrUrlPanel and should check for a valid URL if it 
is a URL entry: 





�Portfolio->Portfolio Image URL �Debug/Run->Image URL (for an image project) 
�Debug/Run->Run Page URL (for a remote project) 




the following Project Create textfields should allow the user to enter a file 
or URL: 




Image->Image URL
Remote->Run Page URL 





appletmanager 

Synopsis: JWS Menu bar icons not consistently greyed out when no project 
selected 



Description: the menu bar icons which aren't capable of being used if a 
project isn't selected (i.e. the edit project, debug, and run icons) don't 
consistenty show as being greyed out. 



to reproduce: 





1.start jws 2.create a new portfolio - and don't add any projects. (note that 
the edit project, debug, and run icons are appropriately "greyed" out) 
3.close tool with that portfolio selected. 4.restart jws 




result: 



even though no Project is selected, all icons indicate usablity (though they 
should be greyed out). ie.. the run icon isn't greyed out, even though there 
isn't anything selected to run... 




appletmanager 

Synopsis: View Source Path on Debug/Browse page does nothing 



Description: 

�bringup jws �select portfolio and project �click on project manager �select 
Debug/Browse page �Click on View Source Path , 




nothing happens. 




appletmanager 

Synopsis: Images are not being added to the run menu 



Description: Just as the synopsis says. 





appletmanager 

Synopsis: Terminal displays IOException when copying project from jdk 
portfolio 



Description: 

�bringup jws �select portfolio jdk, select project blink �click on copy 
project icon - 




the cmdtool window displays "IOException" 




appletmanager 

Synopsis: dev3->dev4, if portfolio created under .jde, get error message at 
startup 



Description: Dev3 uses ~/.jde. Dev4 moves it to ~/.jws. If the user created 
any portfolios under ~/.jde, they will no longer be found. (The personal 
portfolio is a special case, and works.) They will get a popup at startup 
saying the portfolio can't be read. 



Work around: Have the user hand edit the master portfolio file, pointing at 
the new location of the portfolio. 





appletmanager 

Synopsis: initialize Project Import dialog Project File field with .prj 



Description: see synopsis. 





appletmanager 

Synopsis: error message in import project popup is too close to bottom border 
line 



Description: 



Error message in import project popup appear too close to bottom border line 
causing underscore "_" character not to be shown. 





appletmanager 

Synopsis: need to allow spaces in project names 



Description: Projects are currently setup to handle spaces in the source path 
for a project but not in the project name itself. Several customers are 
running into problems because we allow them to enter a project name with a 
space but then they have trouble trying to debug or run their project. 





appletmanager 

Synopsis: ClassCastException - try cloning jws window from newly created jws 
window 



Description: 

�bringup jws �select "New Window" under File menu �go to newly created window 
and �select "Clone Window" under file menu 




get following exception

appletmanager 

Synopsis: jws should have "delete all" button for file list items 



Description: Currently there are 3 buttons for file list items in the project 
page "Add All in directory", "Add Selected...", and "Delete". But there is no 
"Delete All" button. If for some reason users want to delete all list items 
and reconfig a new list they can't. It would take a lot of work to delete one 
by one item of the list. There are several times, I make a mistake of "Add 
All in Directory" and it take me long time to delete unwanted files by doing 
deleting one file at a time. 





appletmanager 

Synopsis: project edit page doesn't get update when current portfolio is 
removed 



Description: 

�create a portfolio �create an applet project (Blink.java) �bring up project 
edit page �remove the current portfolio

personal portfolio now loaded and the current project is the checkers example 
project. But the edit page still contain information from previous Blink.java 
project. 






appletmanager 

Synopsis: can't delete a portfolio in jws once portfolio .psf file is no 
longer existed 



Description: Can't delete a portfolio in jws once the portfolio .psf file is 
no longer existed. 





�create a portfolio p1 in user home directory �from a shell window delete 
file p1.psf �take down jws and bring it up again 
jws give an error message:
"Could not read portfolio 'file:/home/username/p1.psf'" 





there is no way in jws to remove this portfolio because it is not listed in 
portfolio list. 



The portfolio is not listed in other sub-menus and it does get listed in 
File->Remove sub-menu. However, click on File->Remove to remove it, jws give 
out a error message "Could not delete portfolio" and the portfolio will live 
on jws. Could you reopen the bug or should I file a different one. 




appletmanager 

Synopsis: Motif warnings when bring up the Debugger page 



Description: When I clicked on the Debugger tool-bar button to go to the 
Debugger, I got the following warning repeated many times: 


Warning: 
    Name: HorScrollBar
    Class: XmScrollBar
    2054-444 The specified scrollbar value is greater than









appletmanager 

Synopsis: removing current proj in cloned browser doesn't update current proj 
lbl in clone 



Description: 

�Clone the browser �Remove the current project in the cloned browser 




The original browser updates the current project label but the cloned browser 
project label still contains the removed project name 




appletmanager 

Synopsis: copying a project gives incorrect feedback about when copy is 
complete. 



Description: Copy a project with a lot of source files, such as jws. You get 
the icon that the project has been created long before it's done copying all 
the files. Also the performance of the browser is extremely poor while the 
copying is going on. 



(This is because the copy is done on a separate thread. Should probably check 
for thread death before displaying icon - and also maybe have a busy icon. 
Needs more thought.)

builder 

Synopsis: build window does not show the whole long path or classpath 



Description: When a project have a long path or long classpath, the build 
window doesn't show the whole paths on its window. The long path may need to 
be able to wrap around or the window may have to provide a horizontal scroll 
bar for scrolling. 





builder 

Synopsis: build/project doesn't check for "file up to date" correctly 



Description: 





�bring up jde �create a project which have a java file that contained several 
class. 
In my testcase, I used DrawTest.java which contains 3 classes: 
�DrawTest.class �DrawPanel.class, and �DrawControls.class 

�build the project to produce the above 3 class files �delete 2 of the 3 
class files that doesn't have same name as java file. 
In my case, I delete DrawPanel.class and DrawControls.class files 
�build the project again. 




jde build does not build and give out a message "All file are up to date". 



We need output from the compiler for this one. So, it will not be solved in 
the 1.0 timeframe. 




builder 

Synopsis: Build one file doesn't check for file up-to-date 



Description: 



Build one file doesn't check for file up-to-date. 

�bring up jde build page �push-on File toggle �enter a java filename in the 
text field �build the file �build the file again build does the build again 
which it should not. 









builder 

Synopsis: Previous and Next icons on build window don't behave same as ones 
on the editor 



Description: After clicking on the error message, the editor comes up, now if 
I try to use Next and Previous icons on build windows, the highlighted bar 
just flickers but does not go the next or previous error msg location. But 
the Next and Previous icons on the editor works just fine. 





builder 

Synopsis: Previous and Next buttons not disabled before there is output 



Description: Press the build toolbar button, when the builder comes up the 
previous and next error buttons are enabled even though I haven't even 
started a build. 





builder 

Synopsis: The build button should be the first button 



Description: Shouldn't the build button be the first button on the buttonbar, 
and the next/prev be the last buttons? If not, then the String Searcher 
should move it's next/prev buttons to be first. 





builder 

Synopsis: build does not detect recursive build 



Description: 



jde build does not detect the recursive build. 





�create a project which include itself as a subproject �initiate the build 




the build keeps checking for file until it runs out of stack space. 




builder 

Synopsis: can't see end of classpath 



Description: Even when I scrolled all the way to the right, I was unable to 
see the last characters of a classpath (about 2 1/2 times as long as the 
window width) on the display of the build command on the build panel. 





builder 

Synopsis: (PC only) build cmd fails when JAVA_HOME, HOME, and JWS_HOME are 
set to long 



Description: When the JAVA_HOME, JWS_HOME, and HOME are all set to long 
paths, the builder puts up an error msg 'Can't exec ...'. I suspect this is 
due the command-line exceeding 512 characters on the PC. 





builder 

Synopsis: if no existing source file builder faultly say that all files are 
up to date 



Description: 





�create an applet project which have a source file �from a shell eindow 
delete the source file �build the project 




builder replies "All files are up to date" which is incorrect. 




builder 

Synopsis: portfolio/project from last jws session when restarting jws (on 
intel-S2) 



Description: this is a very subtle thing - 



when I am using jws on intel-S2, i expect that when I restart jws on intel-S2 
, it will load the portfolio/project from the last jws intel-S2 session. 





�bring up jws(intel-S2) (rlogin to intel-s2 machine from sparc to run jws) 
�select portfolio/project e.g. applets/TestRect3 �exit jws 

�bring up jws (sparc-S2) �select portfolio/project e.g. jdk/hangman �exit jws 



�bring up jws (intel-S2) �jws loads jdk/hangman as default portfolio/project 
instead of applets/TesTRect3 







builder 

Synopsis: Links are not active in the builder output 



Description: Build an application that has source errors, such as a build all 
on the JWS project. 



The cursor doesn't change shape over the links and a click doesn't do 
anything at all. Next and Prev still work (although the first time you press 
Next error you get the second message, not the first). 





builder 

Synopsis: win95, builder hangs when building a standalone applet 



Description: In Win95, builder hangs when building a standalone applet 



I took the DrawTest example and change filename to lowercase (drawtest.java) 
along with the class name in the file. Here is the drawtest.java file that I 
used as the standalone applet:

Synopsis: JWS build messages disappear after iconifying tool 



Description: From a customer: (verifed on dev4) 



on the Win32 platform only (verifed on NT) 



When I just tried to build a project, and get errors, I minimize (iconify) 
the JWS, and I go to my own shareware editor [...], then I bring up the JWS 
again, to the build manager screen (I know it's the build manager screen 
because the screen has on it the build manager icon bar). I am surprised to 
find that the build manager screen is missing all the text showing me my 
build errors, so I have to build it again to get my errors again.
