Error building struts
Hi!
After building struts, directories "build" and "dist" would be created
under "jakarta-struts" as well the $jakarta_home. The reason for it is
the line in $jakarta-struts/build.xml
<property name="build.dir" value="../build/taglibs"/>
...
<target name="jspspec">
<ant dir="./jspspec" target="dist"/>
</target>
However, the property cannot be replaced by the
$jakara-struts/jspspec/web.xml (with inner scope)
<property name="build.dir" value="../../build/taglibs"/>
Is there any fix for the current implementation of ant?
Thanks
Arion

Project.resolveFile() would do, if you code it up in Java. I don't see
any other way right now.

Whatever you prefer.

I think it would. Try it 8^)

Hi!
Is there anyway to resolve the $servlet.jar from absolute/relative to
absolute?
Should the classpath be separated with : (Unix style) or ; (Windows style)
or both are acceptable?
For the second approach, would ./ do the same work as sub/../ ?
Thanks

I'm afraid there is no easy solution that will always work. If the
property is only going to be used in CLASSPATH constructs, you could
just simply say
<ant>
<property name="servlet.jar" value="../${servlet.jar}:${servlet.jar}">
</ant>
the non existing part is going to be thrown out by javac, java or
whatever you are going to use.
A more general - and more ugly - solution would be
<target name="check">
<available property="is.relative" file="sub/../${servlet.jar}" />
</target>
<target name="subrelative" depends="check" if="is.relative">
<ant>
<property name="servlet.jar" value="../${servlet.jar}">
</ant>
</target>
<target name="subabsolute" depends="check" unless="is.relative">
<ant>
</target>
<target name="sub" depends="subrelative,subabsolute" />

Hi!
Sorry I haven't state my question clearly.
The problem is the property sevlet.jar. The parameter can be set from
the environment. The value may indicate a relative path (eg
"../jakarta-servletapi/lib/servlet.jar") or absolute path (eg
c:\servletapi\servlet.jar)
What I want to do is, for the first case:
<ant>
<property name="servlet.jar" value="../${servlet.jar}">
</ant>
and untoucth the value for the second case.
What should I do?

The dir attribute of the ant task or the value of the build.dir
property? What is the problem you face?

yup your right.

Hmmm .... I was thinking basedir property is actually overidden when the
second one.xml is read - resetting the directory to "." most likely. Which
would make sense in single project but in two project set up where second
build file is another directory we have to have some way of making the
basedir specified in build.xml relative to the basedir supplied in Ant
task. Does that make sense ???
Cheers,
Pete

I think you are wrong here Pete. dir is a File not a String so the
slash shouldn't matter (talking of the CVS version).
The problem seems to persist with the latest CVS version though. I'm
having another look.

Badly resolved files in Ant task
Posted by Peter Donald <do...@mad.scientist.com>.
Hi,
There was just a report on users list of badly resolving names and dirs in
ant task.
The problem is that
<ant antfile="one.xml" dir="1.0"/>
resolves to "one.xml" not "1.0/one.xml". The reason is that on line 179 of
Ant.java you use "new File(dir, antFile)" which because dir doesn't end
with a file seperator doesn't resolve properly. To fix check if dir ends in
a seperator and if not add one. (Alternatively you could fix it the same
way I said a while back re fixing similar case in Javadoc task)
Cheers,
Pete

Hi!
What should I do if the path maybe absolute? How can I distinguish
between the two and write the appropriate thing?
Thanks

Try
<target name="jspspec">
<ant dir="./jspspec" target="dist">
<property name="build.dir" value="../../build/taglibs"/>
</ant>
</target>
Does this work?
