SAXParseException and maven
Well, I continued getting these 'org.xml.sax.SAXParseException: Content is not
allowed in prolog' this morning :(
However, I might have spotted something:
I took the struts-demo application which is working fine. The war file for this
application was created by using 'maven quickstart' and is the one deployed
into JetSpeed.
I then went into the root directory of the struts-demo application and deleted
the target directory. I then typed 'maven war' and replaced the original file
deployed into jetspeed by this one (after correctly undeploying it). Guess
what ?
I started getting 'org.xml.sax.SAXParseException: Content is not
allowed in prolog' when Jetspeed tried to re-deploy it. I looked at the 2 war
files and they were not of the same size (difference of 2.79 MB and 2.80 MB).
So my question is: Would all the problem be actually linked to an incorrect
encoding or creation of the war files by maven ? All the exceptions I was
getting were due to portlet.xml files created with the simple 'maven war'
command...

Hi,
I am getting these stange org.xml.sax.SAXParseException: Content is not
allowed in prolog and I don't understand why...
Anybody would have a clue where I shoul start looking ? (I see nothing wrong in
my config XML files...)
I am trying to make a simple struts-portlet work...
Thanks in advance

Re: SAXParseException and maven
Posted by Xavier Lawrence <xa...@epfl.ch>.
Ok, so I solved my problem.
The problem was actually Ultra-Edit adding BOM headers to all UTF-8 files
automatically. This was nasty as this configuration is the default one...
The header was 2 characters placed before <?xml...?>

Re: SAXParseException and maven
Posted by Jaq Marit <ic...@slu.edu.ph>.
I had a similar experience. Being a sax exception, there must be something
wrong with one of the xml files (mostly config files). My observation is that
jetspeed tries to process and possibly write to config files causing the xml
files to be modified. At some point, my apps server did crash or did not exit
gracefully and I encountered 'Content is not allowed in prolog' errors. So I
had to look at the xml files, and I saw an empty xml (config) file. Your
problem may not be similar to mine but you could consider checking each xml
file again.
