AW: How to use jikes
Create an environment variable with the name JIKESPATH and add tools.jar and rt.jar to it (just like in the CLASSPATH variable). -Ursprüngliche Nachricht- Von: Martin Monsorno [mailto:[EMAIL PROTECTED] Gesendet: Donnerstag, 31. Juli 2003 17:12 An: [EMAIL PROTECTED] Betreff: How to use jikes Hi *, I want to use jikes to compile my classes, but it complains that it does not find the java standard library classes. The compilation buffer says: , | cd /home/monsorno/java | jikes -classpath /home/monsorno/java/lib/bla.jar -sourcepath /home/monsorno/java/src -d /home/monsorno/java/classes Dings.java | | Found 2 system errors: | | *** Error: Could not find package java/util in: | /home/monsorno/java/lib/bla.jar ` Must I add $JAVA_HOME/jre/lib/rt.jar manually to my project's classpath? And if yes, how can I use $JAVA_HOME to make it independant from my local environment? Or wouldn't it be better if JDEE would add this automatically to the classpath, if jikes is set as the compiler? (I'm using xemacs 21.4.13 on Linux, JDEE 2.2.8 and jikes 1.15) -- Martin
Problems setting ant build directory
Hi, I an occasional JDEE user, using JDEE 2.3.3-beta5 from Cygwin/XFree86 2.0 on Windows 2000. I want to use jde-ant as build method, e.g. to get ant target auto-completion. But I have not succeeded to set the ant build home to my project top level directory (where my build.xml as well as prj.el resides). Typically the build command starts with a cd to the location of the current Java source file and the build.xml is not found. If I set jde-ant-enable-find to off, the build.xml is found, but ant is still run from deep down in src file tree. I have found posts about this earlier in the mail archive, the recommendation then was then to use make as build method and give ant as build program. This is my current setting, but I have to hard-code the path to my project directory to get it to work as I want. Generally in specifying JDEE directory locations, are there ways to specify paths relative to the prj.el and/or build.xml locations that works together with Cygwin path translation?

The JDEE already includes a function for wrapping a region

RE: Useful helper functions
Paul,
Actually I have a question about region based cflow templates. How do I
use them?
I ask because, with region, as soon as I type first letter of 'if' or
'try' the mark (region) is deactivated.
Or the only way to use the functionality is by marking a region and then
doing one of:
1. M-x jde-gen-try-catch-wrapper RET
2. Bing the function to some key or menu and use that keystroke/menu
selection
Am I missing something here?

No. The cflow templates do not currently support wrapping
a region in a cflow construct. The try-catch, if-then, etc.
templates do include a tempo region element so it appears
that the author's intention was to support region wrapping.
To activate this requires setting tempo-insert-region to
a nonnil value. However, when I try this with the if-then
template, the template simply deleted the region and generates
the final brace above the if line. There seems to be a bug
in the template or tempo. I will look into this further and
try to get the templates to wrap themselves around a region
if a region is selected.

I have:

My original question was can I avoid

I verified that the cflow templates do indeed work if you execute them
directly but not if you invoke them via abbrev mode expansion. I do
not know if there is a way to get them to work when invoked via
abbrev-mode expansion. If not, I could write a set of wrapper
functions that locally set tempo-insert-region on and then invoke the
corresponding template, e.g.,
(defun jde-wrap-if ()

(let ((tempo-insert-region t))
(jde-gen-if)))

Any thoughts? sandip I'm guessing that hard to do without intercepting every keystroke. For the reason you stated, once you start typing, the region will be deactivated. I'd say it's possible with emacs, but we'd have to implement a previous-region variable, and if a user types a non-command key then if there is a region, it stores it in the previous-region variable. And once a completion fails (a user types in a non-keyword), we'd have to clear that previous region function. So, possible, but difficult. Unless a facility for storing previous regions exists already, but I was unable to find it.
