I am getting some requests from NT users on an application that I wrote on
a Java/Linux environment. I have a Java application that runs fine on Unix
and I am trying to get to run perfectly on NT. I have a run time shell
script that passes the entire environment to the JVM using a system
property.
java -Denv=`env` xenon.xsql.editor.Xsql
The env produces the multiline environment variables list that we know and
love. On running the application the program looks for the value of system
property called `env'. Hence the JVM gets the entire environment. I have
source code that breaks down the multiline value and cuts out each variable
definition like `HOME=/home/peterp'. The definition is further split into a
name and value (`HOME' and `/home/peterp') and then place stored in the
system properties as renamed property `env.HOME' and `/home/peterp'. In
short all the environment variable are prepended with `env.'. Using this
hand-me-down old deprecated source code from an unknown URL, I can write
code like this:
String imagesDir=System.getProperty("env.IMAGES_DIR");
String searchPath=System.getProperty("env.JAVAFILESEARCHPATH");
Of course this does not work with Windows NT (or 95/98). I am not an expert
on NT. I do not think there is an equivalent for `env' under NT.
Is there such thing ?
Of course I could write a work around that involve just passing a limited
number of properties to JVM in a NT batch command `.BAT' file.
java -DIMAGES_DIR=%IMAGES_DIR% ... xenon.sql.editor.Xsql
Admittedly the full final code would look terrible ugly. I am clueless if
the DOS? W95/NT Shell allows long character lines. Can you even do `back
subtitution' using the W95/NT shell is also quite another thing as well?
Also when I tried extending my `PATH' under W95 I got `out of environment
space' or something?
However do any other java-linuxers know of a better solution or API?
Any help receives my grateful kudos.
Pete
