Hello,
Once again I find myself of classpath/jar hades.
:-P
I have the following code that runs on my development machine fine:
FileInputStream is = new FileInputStream(this.poolDir + poolName
+ "/" + Constants.FILENAME_PROPERTIES);
SAXBuilder builder = new SAXBuilder();
Document propertiesDoc = builder.build(is);
XPath xPath = XPath.newInstance(Constants.XPATH_TAGLINE);
However, when I deploy, I get the below exception on the Xpath
xPath = ... line.
Are you certain this is not on this line? Perhaps the code on your
machine and on the server is different (different line numbers)?
SAXBuilder builder = new SAXBuilder();

I've setup my build I think to include all the needed jar files (I
put them in a jars subdirectory of my project - all from here:
http://www.jdom.org/) according to this:
<target name="build.woapp">
....
<woapplication ...>
...
<lib dir="Libraries">
<include name="jars/*.jar"/>
<exclude name="**/*.woa/**"/>
</lib>
</woapplication>
</target>
And since there's no error on the below two lines I'm thinking the
jars are getting included in my deployed build (btw, is there any
way I check for sure that the jars are included by looking at the
deployment bundle?)
Look in AppName.woa/Contents/Resources/Java and also (very, very
carefully) at the classpath at AppName.woa/Contents/MacOS/
MacOSClassPath.txt
SAXBuilder builder = new SAXBuilder();
Document propertiesDoc = builder.build(is);
So, any ideas why it can't seems to find the SAXBuilder class on my
deployment machine when it does find it on the development
machine? Seems I can never deploy any new jars without running
into trouble like this, wish I could figure it out once and for all.
If the above does not show the problem, the next place to look is /
Library/Java/Extensions and /Library/WebObjects/Extensions for
conflicting versions.
