Need help on setting jvmarg
Hi all, I'm using ant as my building tool. I have written some test case for my project and ran via goal. In this case i made fork="true" and ran on Linux (Ubuntu) system and worked perfectly. But when i try to run it on a Windos XP machine, rather than running the test cases, and when excuiting the goal, i get a help to "java", which is pertty wierad. Could some pro kindly tell me, what have i done false here. Any aid will be highly apprciated. Thanks, Saminda ___ How much free photo storage do you get?

RE: and failifexecutionfails
I must admit that this area seems to be a real shortcoming in existing ANT tasks - not being able to reliably swallow errors in subtasks, whatever they may be. When I was trying to solve this problem before, there were suggestions as to how I can check that the specific task (tomcat undeploy) would succeed before executing it, rather than being able to support a failonerror property. This pre-validation is of course much more complex and less useful for similar problems but which aren't for tomcat related tasks. Is there a straightforward way to create a Task which swallows errors generically, regardless of the type of task. Can it be built?

You have to remember that Ant is designed to be a build tool, first and foremost, not a generic workflow system. It is only later, as things like deployment get involved, that you do start thinking about fault handling, cleanup etc. And in most builds, a simple "build failed" response is exactly right. The build failed: something didn't work. Many tasks have failonerror attributes, but that is still fairly simple error handling, it is "ignore specific errors here"; not real fault handling at all. 1. you can use to search a path (eg. env.Path and env.PATH) for an executable. You need to include the .exe extension for windows, assuming is an executable. 2. try/catch from ant-contrib will catch faults and let you handle them properly. -steve - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: where is the problem?
Hello Aydin, Ant+Eclipse is a slightly diffferent animal than Ant all alone - depending on how you have your classpath setup for compiling (basically - explicitly listed in build.xml vs imported as a property vs set in your environment) you may have to mess about with Eclipse's Ant runtime preferences (Window -> Preferences -> Ant -> Runtime) /t >-Original Message- >From: Aydın Toprak [mailto:[EMAIL PROTECTED] >Sent: Tuesday, September 20, 2005 2:33 PM >To: Ant Users List >Subject: Re: where is the problem? > >Thanks Barry, >But I have already added those paths to my enviroment and everything >(excep this) works smoothly.. how ever, it still resists about the >missing packages.. but I have them and can compile the java >code on the >command promp, in the same directory.. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: where is the problem?
Ant must be using a different environment then, because it can't find
javax.servlet
My advice would be to forget eclipse for now and get the build working
on the command line. How many javac's do you have on your system? Which
one is in your PATH? What is JAVA_HOME set to? If JAVA_HOME is set to a
J2SE installation there will be no javax.servlet in the classpath -
unless explicitly set in CLASSPATH or in the build file.
Eclipse may just confuse matters while you are learning Ant. Get back to
basics and make sure Ant is set up correctly. I only use eclipse for
code editing - Ant does the rest.
Good luck,
Barry

I have solved the problem.
The problem is all about the libraries (.jar files) that we have to add
the ant runtime which is in the
eclipse(window->preferances->ant->runtime)...
I used to add the related libraries like j2ee.jar... however whenever I
add those important libraries to the runtime enviroment and close the
window, every thing that I have added dissapears (as far as I
understood, ant envirement didnt include them!) ... but when I added
thoses libraries under the global entries, I have succeded... now
everthing stays :)...
it is a dramtic stiuation for a proffessional..
but I am still learning.. :)

Extracting application version from Java file

Re: Extracting application version from Java file
You're going to wrong way.
Pass into your Ant build the version number like so: ant
-Dversion=XX.YY.ZZ clean build test.
Then use the task to replace a token in your Java file. Even
better, you store that number in MANIFEST.MF and update it with the
task. Or, use a properties file. That way your dev's aren't the ones that
set the version, your build controller/cm person does.
Oh, and just grab ${version} and use it in your task like so: ...

Re: Extracting application version from Java file
Hi Nicolas,
how about controlling the version number in the build?
then update the version in the source file on every build:
and then compile and use ${version} to name the jar?

Re: Extracting application version from Java file
We go one step further..
In the code base there is a build.properties file with
the
following data:
build.version=XX.YY.ZZ
build.date=2005-09-21
build.date.format=-mm-dd
Then instead of a static variable in Java class (say
called BuildInfo.java) we have static method called
getBuildVersion() (and getBuildDate()) which read the
build.properties file, cache the results and return
the value the callee.
Our build process (using CruiseControl) writes/updates
the build.properties file only... Build.java is not
modified.
Hope that helps,

RE: Extracting application version from Java file
Hello List,
I was going to reply to Nicolas that, whilst i agree with the other two
replies (you should pass the version in somehow and not read it from the
java source file), you *can* achieve what he is trying to do using the
task with a nested filterchain. But i
can't seem to get it to work. I've posted my example below, can anybody
see what i'm doing wrong?
--mytest.java
public class mytest
{
public static final String VERSION = "XX.YY.ZZ";
public static void main(String[] args)
{
System.out.println("Hello, World!");
}
}
--build.xml
${VERSION}
i get a "Unable to load file: java.io.IOException" message. I've tried
putting a static properties file and loading that - no probs. I've tried
copying the class to a properties file by using the classconstants
filterchain... didn't work (same error).

RE: Extracting application version from Java file
Sorted - i didn't have the bcel.jar in my lib folder. Added it and it
works fine.
Sooo - Nicolas, *if* you have bcel.jar installed, you can use
the example below to get your version string out of your file!
(but you shouldn't ;)

ANT build script from NetBeans is failing
I'm using NetBeans to manage a few Java projects. Recently I found a
need to build manually with the command line (read: scriptable) ant, and
I found that one of the three projects would sometimes fail.
On the NetBeans machine (windows + cygwin), the ant build works fine.
The same directory copied to two other machines (linux boxes) fails.
Clearing the classpath, -debug and -verbose don't seem to offer any
clues. Here's the output:
-pre-compile:
-do-compile:
[javac] Compiling 98 source files to
/root/tmpdev/svn_buildtest__2005.09.20..10.52.56/trunk/netbeans/CFApplet/build/classes

[javac] found : java.lang.Integer
[javac] required: int
[javac] return (Integer) ret;
[javac]^
[javac]
It seems as though the classpath is messed up, but the other projects
build just fine.
What can I do to further diagnose what is going on? Is there a
fundamental incompatibility between NetBeans auto-generated scripts and
manual ant building?
(NetBeans 4.1, ant 1.6.5)

RE: Extracting application version from Java file
Thanks for this solution :)
I am considering where I should put the version (in a Java file, a
property file or in the build.xml)
The pros and the cons:
1) in build.xml:
I don't like it because :
- two files are modified and need to be committed when the version is
changed (build.xml and java).
- requires to run Ant to put the correct version in the program. I am
working under Eclipse, so Ant is only used when I need to make a
distribution.
2) in a property file:
Seems better.
Need to modify the program and the build file at first, but after only
one property file.
2) in the Java file:
That was my first idea.
Need to modify only the build file at first, and after only the java
file.
After your first mail, I had a look at and found an other
way to do it.
It doesn't require bcel, because I can directly parse the java source
code.
Not very elegant, but works:
Well,
thanks a lot for the ideas
Have to decide what way to go with ;)

If I am wrong, still need your help. :) no, you need to look at the detailed jvm args and paste it in to your next mail. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] Interop tests for doc-lit, code generated samples - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
