Re: [configuration] VerifyError

Oliver,

Checked the Run->Classpath tab in Eclipse IDE and sure enough it had every cots library in a specific directory listed. Even those not specified in my project's->Properties->Java Build Path->Libraries 8-( I removed the defaults and added the required cots libs as below and it executed just fine. Many thanks for the pointer...

hopp

Is it possible that an old version of Xerces lies in your JDK/JRE lib/ext directory? It appears at least in the stack trace.

Looks like a problem with the XML parser you use. Which parsers do you have in your classpath?

If you use JDK 1.4.x, you don't have to bother about including a specific parser; you can simply use the one shipped with the JDK. For earlier JDKs in our dependencies we have defined Xerces in version 2.2.1.

Good day,

Thought that configuration might be an easy replacement for my properties configurator since it does both UNIX based key=value properties but also xml config files. Mine only does the former 8-(

While setting up my test I came across an error while setting up this from example:

#more config.xml
<?xml version="1.0" encoding="ISO-8859-1" ?>

<configuration>
    <properties fileName="usergui.properties"/>
    <xml fileName="gui.xml"/>
</configuration>

My src code works fine with just the properties "fileName" but I get a
