NullPointerException in PropertyHelper.setProperty
Hi, I don't know if I am in the right forum. I have the following problem. I
have create a Web Service which transforms a file from html to xml. When I
call that WS I get the following error:
java.lang.NullPointerException at java.util.Hashtable.put(Unknown Source)
at org.apache.tools.ant.PropertyHelper.setProperty(PropertyHelper.java:330)
at org.apache.tools.ant.Project.setPropertyInternal(Project.java:568)
at org.apache.tools.ant.Project.setSystemProperties(Project.java:913)
at org.apache.tools.ant.Project.initProperties(Project.java:307)
at org.apache.tools.ant.Project.init(Project.java:295)
That error occurs when the the following piece of code is executed:
ProjectHelper helper = ProjectHelper.getProjectHelper();
p.addReference("ant.projectHelper", helper);
p.fireBuildStarted();
--->here is the error
p.init();
helper.parse(p, buildFile);
p.executeTarget(p.getDefaultTarget());
p.fireBuildFinished(null);
Could you help me to solve that problem?? Thanks in advance!

Hi again,
and thanks for your reply Jan,
the problem occurs when I call the init() function wherever it is placed. I
have try many different positions for that function but it fails. The last
test I made was the following:
Project p = new Project();
p.init();
...BUT NOTHING AGAIN :-( . Ιs it possible to happens a conflict with another
java library I use? Any suggestion??
Thank you again!!!

Mmmh ... do you think telling the project instance that the build is
staring
is ok here? BEFORE you have initialized the project and parsed the
buildfile?
