getDeclaredFiel ds() not returning full list on IBM JAVA SE5?

1 New Member

Just tried running some code on Linux (2.4.21-32.0.1.EL and Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_04-b05)) and Windows XPSP2 (with Java HotSpot(TM) Client VM (build 1.5.0_11-b03, mixed mode, sharing)) and in both cases, get the following list returned from calling getDeclaredFiel ds() on java.lang.Class Loader via this code snippet:

Field[] fields = loaderClass.get DeclaredFields( );
for (int i = 0; i < fields.length; i++) {
System.out.prin tln("fieldName = " + fieldName);
}

fieldName = private boolean java.lang.Class Loader.initiali zed

When I run the same code on AIX 5.2 with IBM J9 VM (build 2.3, J2RE 1.5.0 IBM J9 2.3 AIX ppc64-64
I get:

FieldName string = private static boolean java.lang.Class Loader.initSyst emClassLoader

FieldName string = private java.security.P rotectionDomain java.lang.Class Loader.defaultP rotectionDomain
FieldName string = private java.util.Hasht able java.lang.Class Loader.contexts

I'm actually searching for nativeLibraries and SystemNativeLib raries, which is present in the first instance and not the second. Is the IBM Java version organised differently?

Thanks

Error when returning a collection from a web service

by: Simon Harris | last post by:

I am trying to create a web service that returns a collection. It keeps complaining that I need to specifiy a default accessor. I have searched Google over and over for this - Lots of results, none of which really make full sense to me. I understand that this is related to serialization, and that I need to add default properties - Something about enabling the web service to reference each object in my collection by its index.

question about xmlrpc server: returning a list of lists to a Java client?

by: fortepianissimo | last post by:

I have a simple xmlrpc server/client written in Python, and the client throws a list of lists to the server and gets back a list of lists. This runs without a problem. I then wrote a simple Java xmlrpc client and it calls the python server. But I can't figure out what type to cast the result (of type Object) to. The Java xmlrpc call is basically this: Object result = client.execute("MyFunction", params);

returning regex matches as lists

by: Jonathan Lukens | last post by:

I am in the last phase of building a Django app based on something I wrote in Java a while back. Right now I am stuck on how to return the matches of a regular expression as a list *at all*, and in particular given that the regex has a number of groupings. The only method I've seen that returns a list is .findall(string), but then I get back the groups as tuples, which is sort of a problem. Thank you, Jonathan
