Hi,

I am calling a .NET web service from an axis client running on tomcat 5.0.
I got [ns1:VerifyEmailResult: null] as a result while I got the perfect xml response when I run this program as standalone.

Here's what I printed on the screen

Result: [ns1:VerifyEmailResult: null]
[Fatal Error] :1:1: Content is not allowed in prolog.
org.xml.sax.SAXParseException: Content is not allowed in prolog.
at org.apache.xerces.parsers.DOMParser.parse(Unknown Source)
at org.apache.xerces.jaxp.DocumentBuilderImpl.parse(Unknown Source)
....

Notice that I also got an error 'Content is not allowed in prolog'. Is it because the program trying to parse illegal xml string?

One more thing, In standalone app, I use crimson as a parser, but tomcat uses xerces. I tested more by adding xerces lib to my standalone app and I got the same error as I got from tomcat.
It seems like xerces is the real problem. How do I solve this problem?
I'm not sure that I can remove xerces lib from my web app.

P.S. I've tried using crimson instead of xerces by setting these system properties

<system-property javax.xml.parsers.DocumentBuilderFactory=
"org.apache.crimson.jaxp.DocumentBuilderFactoryImpl"/>
<system-property javax.xml.parsers.SAXParserFactory=
"org.apache.crimson.jaxp.SAXParserFactoryImpl""/>

but it led me to another error

java.lang.IllegalStateException: can't declare any more prefixes in this context

Yes, you can use it. But I would say that it's a bit too complicated.
- Error is not an exception.
- The rule that overridden method can't throw Exception that never throw apply only checked exception,so InnerB can throw RuntimeException without problems.
Thank you for reply
Now I got the solution.
The solution is update Log4J to lastest version.

First,I don't have any problem every seem work fine,but after I included Log4J in environment of server(Weblogic)
I got LogConfigurationException thrown from common-logging when I tried to deploy the same web applicatin that used to work.

Hi,

The HashMap roughly equivalent to HashTable, except
that it is unsynchronized and permits nulls
