Loading local JRE classes tries first from document base (jaxp?)

Question

I am using JAXP in my applet with JRE 1.5. I have set the system property for JAXP to find the correct implementation. Both the implementation and the JAXP "interface" files are located in rt.jar in the local JRE installation.
But everytime I call a JAXP class it first looks under my document base, in this case the jar file from server where the applet code is! Worse is, ity thinks that is a directory and checks "under" that directory.
Finally, it does not find the JAXP classes in that jar (on the server), and it finds it locally. But this generates much network traffic.
Is it possible to tell JVM how to find it's classes in rt.jar?
This is the console debug logging:
network: Connecting http://xx.xxx.xxx/xx/applet/egate.jar/META-INF/services/javax.xml.transform.TransformerFactory with proxy=DIRECT

Answer 1

I have built a desktop application that can use these
calls to check if the xml contained in the document
called "file" is well formed.
Ok. So, the application works fine then?
DocumentBuilderFactory domFactory =
DocumentBuilderFactory.newInstance();
DocumentBuilder domBuilder =
lder domBuilder = domFactory.newDocumentBuilder();
     domBuilder.parse(file);
They are part of the javax.xml.parsers.*; package.
Problem is that to serve this I need to put it in an
applet but since I have to write the xml string to a
file local to the server the applet is not working.
Huh? You lost me there. Are you getting security exceptions from the applet? If yes, you need to sign the applet. Otherwise, what is not 'working' in the applet compared to the application? Also, why do you need to first write it to a file?
My question is if anyone knows of some classes in the
API that will allow me to check if a String of XML is
well formed or not.
If the document is not well-formed, the parse() call will throw an exception. Catch this and process as needed.
I basically need to get a string from a field in a
data base in XML format and be able to test it
without first writing it to a document so I can get
the applet to work.
If you want to access an external database from an applet, you will need to sign the applet. You should not need to first write it to a file before parsing. Rather, simply use a stream (either InputStream or Reader) and wrap it in a StreamSource object.
If anyone knows something on this or has an
alternative suggestion please do tell.
