Subject NullPointerException in PropertyHelper.setProperty
Date Wed, 28 May 2008 17:18:29 GMT

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!
