PATCH: max-lisp-eval-depth exceeded on CVS Emacs
After a fresh install of Emacs and JDE on a new machine, I found that a patch I thought I'd submitted some time ago is not in either JDE 2.3.5 or CVS. The problem is caused by a change in behaviour of (expand-file-name .. dir) when dir is the root directory on a Windows drive. In previous versions, the result was D:/.., but in the current CVS code, (expand-file-name .. D:/) returns D:/, which is consistent with what happens on *nix. The following patch adds support for this in jde-root-dir-p, avoiding some infinite loops: *** c:/site-lisp/jde-2.3.5/lisp/jde.el~2004-12-16 22:29:36.0 + --- c:/site-lisp/jde-2.3.5/lisp/jde.el2005-09-21 17:29:28.89250 +0100 *** *** 1595,1601 (or (string= parent //) ; for paths like //host/d/prj/src (string= parent ) ; for paths like \\host\d\prj\src !(string= (substring parent -3) /..))) ; for paths like d:/prj/src ((member system-type '(cygwin32 cygwin)) (or (string= (file-truename dir) (file-truename /)) (string= parent //) ; for paths like //host/d/prj/src --- 1595,1602 (or (string= parent //) ; for paths like //host/d/prj/src (string= parent ) ; for paths like \\host\d\prj\src !(string= (substring parent -3) /..) !(string= parent dir))) ; for paths like d:/prj/src ((member system-type '(cygwin32 cygwin)) (or (string= (file-truename dir) (file-truename /)) (string= parent //) ; for paths like //host/d/prj/src
Re: cygwin emacs path problem
Paul Kinnucan wrote: Hi Felix, As I understand it, there are two versions of cygwin emacs: (A) a version of Unix Emacs modified specifically to run in the Cygwin environment and (B) the standard Unix version of Emacs compiled, using cygwin gcc, to run in the Cygwin environment JDEE supports the A version. It does not support the B version. The reason for this is that years ago, long before the B-version existed, some JDEE users asked for A version support and some of those users actually contributed code necessary to support the A version. Meanwhile, until now, there has been no demand for B-version support. Really this is a cygwin problem. A cygwin version of Emacs needs to be modified to fit its environment, as the 'A' version was. I'm not sure what happened to those patches, but it is unreasonable of the Cygwin maintainers to expect the maintainers of every other package to make changes to accomodate Cygwin's lack of fitting in with its environment so that they themselves can use unmodified code targetted at GNU/Linux.

Patch: File menu in recent CVS Emacs no longer called 'files
The File menu has recently been renamed from 'files to 'file in Emacs CVS. This has revealed a dependancy in JDEE that can easily be fixed by using menu-bar-file-menu (which has existed since at least 19.27) which also simplifies the code a little: *** jde.el-orig Fri Oct 29 00:43:02 2004 --- jde.el Wed Nov 10 23:09:59 2004 *** *** 1247,1258 (when (fboundp 'add-submenu) (add-submenu '(File) val Insert File...)))

Re: Feedback needed on w3m support
Paul Kinnucan wrote: I'd also appreciate it if someone who is using w3m on Unix would take a look at the URL that the JDEE generates for local files and tell me what's wrong with it and what URL would be acceptable to w3m. There was a thread about this last week. The problem is a double slash between the host part and filename part of the URL. A patch was posted, which I think will break things on Windows, since it replaced //localhost/ with //. I think a better solution is to look at the filename, and if it starts with a slash (Unix), use //localhost or //, and if it doesn't (Windows), then use //localhost/ or ///.
Re: JDE 2.3.4beta3: strange overlining
Eric M. Ludlam [EMAIL PROTECTED] writes: I'm getting the weird effect shown in the attached GIF using JDE 2.3.4beta3 and cedet1.0beta2 on Emacs 21.3. All non-public methods are 'overlined', which is really not pleasant. I guess it's some kind of highlighting of non-public methods that has gone wrong - does anybody know of a configuration setting to modify this behaviour or is it possibly a bug? [ ... ] That is part of `semantic-show-tag-boundaries-mode'. It actually overlines any method over a certain length (In characters.) No, I think the original poster is talking about the highlighting of private and protected methods. For some reason the default face for private members is a cyan overbar (but colors for overbars don't seem to work, on Windows at least), and rather than just over the function name, it is over every line of the function - that is annoying, and what is also annoying is that if you customize it to off and save, next time you start Emacs, the customization does not take effect because it is executed before semantic-turn-on-everything (or useful-things). The doc string says that the default face is a background color, incidently.

Does anyone know what the story is here? If you got the Windows binaries from ftp.gnu.org, then there is a problem with them.

Re: XEmacs and Eclipse
Shashank [EMAIL PROTECTED] writes: But recently looks like it has lost momentum for supporting new features for development like testing, J2EE ? Since you are replying to me and Michael Coughlan, I can only assume this is in response to my earlier reply to Michael. If so, you have misunderstood my reply. All I said was that XML editing is not JDE's responsibility, not that Emacs does not support it. There are many people that use XML that are not interested in Java and vice-versa, so it makes sense to keep the support for XML and Java seperate.
Re: IPlanet serverside debugging?
[EMAIL PROTECTED] writes: We can't control how it starts, but we still might be able to connect to the running process. You should be able to control how iAS starts jvm's e.g. see http://docs.sun.com/source/816-7149-10/dgdebug.html#25712 Unfortunately those docs are for Sun ONE app server 7, which is a complete rewrite based on Tomcat, and bears little resemblance to iAS 6. Last I checked, Sun had purged their webserver of references to old iPlanet documentation, or at least made it hard to find.
Re: IPlanet serverside debugging?
Galen Boyer [EMAIL PROTECTED] writes: Is this doable within the jdee? Which iPlanet? App Server and Web Server are completely different products. I think iAS uses a standard JVM, in which case using the remote debugging options would work. But I think iWS uses its own JVM (from the Kiva days) and implements part of the Servlet API as native code, so it might be more difficult. If you are trying to debug something general in your servlet, running it under Tomcat (or JBoss if you need more than just servlets/JSPs) is probably easiest. If you are trying to debug something specific to iPlanet, and can't run under a debugger, System.out.print() is your friend.
Re: IPlanet serverside debugging?
Paul Kinnucan [EMAIL PROTECTED] writes: If you are trying to debug a program running in a vm embedded in another application, the container application must provide some means for you to tell it to start the embedded vm in debug server or client mode. Often there is somewhere to specify command-line options to Java in shell scripts/batch files that start the app server, or occasionally in the config interface.

Re: Fix for a problem in saving project file (2)...
[EMAIL PROTECTED] (Ping Liang) writes: I have never needed to deal with Windows/Unix issues before, so I am not familiar with directory-sep-char. I guess that there must be a better way to deal with this if it is to be deprecated. It is deprecated in GNU Emacs. I am not sure of its status in XEmacs (it appears it is still needed there). The reason for deprecating it is clearly illustrated by this particular problem. I think the correct fix is to only bind directory-sep-char around the one line of code that requires it: (defun jde-find-project-file (dir) Finds the next project file upwards in the directory tree from DIR. Returns nil if it cannot find a project file in DIR or an ascendant directory.

Re: Whay is JDE/Xemacs startup so slow?

I am running xemacs 21.1 on a solaris server box (I'm not sure its exact speed). Without jde it takes just a second to start xemacs. There are many messages about loading regexp-opt on the status line. Is there some sort of debug I should turn on to track what it is doing? The JDE is a big, complex application that requires about 30 lisp packages It may still be worth debugging, since regexp-opt should only be loaded once. The total time to load JDE on my system is 4 seconds, although if the solaris box has the directory where JDE lives mounted via NFS, or is very old, 20 seconds might be reasonable. -- Jason Rumney

You sound like you are unaware of the menu-bar that has been a feature of Emacs since the 18.x days. I don't remember the last time I needed to do anything in JDE that wasn't accessible from the menu-bar (even if I did find it quicker to use the keyboard). -- Jason Rumney
Re: Help Needed Debugging Tomcat Servelets
Heather Marie Buch [EMAIL PROTECTED] writes: I'm sorry, but could you please give me the syntax for setting it in startup.sh? I tried just writing the line TOMCAT_OPTS=value try adding the following line as well export TOMCAT_OPTS and make sure you are starting Tomcat with startup.sh, not tomcat.sh start. Also, even when I set the TOMCAT_OPTS in tomcat.sh and start tomcat, and it echos that the opts are set to the debugging stuff, when I run netstat -a it doesn't show my tomcat socket number, so is tomcat really running on that socket? I don't know. I would expect the socket to show up in netstat -a. But the real test is if JDEbug can attach to the process. Is this what I would do? startup tomcat and apache with debugging opts go into emacs, open the java file start jdedebug attach process set breakpoint open servlet in browser Yes. then what? Then wait for your breakpoint to be hit. Or would I open the servlet in the browser in between attaching and setting the breakpoint? That would work too, unless you are trying to debug the servlet's init method, since that only runs the first time you connect. So, it looks like now I just need a way to make sure tomcat is starting on that socket, and the proper order to run the debugging. Hopefully the above will help. -- Jason Rumney
