CSSDK GETCLIENT NullPointerException

speck

Upgrading from 6.5 to 6.7.2... recompiling code with NEW CSSDK libraries using java 1.4.2.. have the libraries in my path, from the CSSDK client /java 1.4 directory,

The code properly creates a factory, but the call to getClient DIES with NULL POINTER EXCEPTION... I am at a loss. Doesn't throw any of the CS exceptions just NULL POINTER From the getClient call.. This is effectively same code that works fine and all Javadoc says this should still work, but no matter what I do under CSSDK 3.0, I don't get past this. Always a NULL POINTER EXCEPTION... any ideas?


snippet below:




// create the factory
try {
factory = CSFactory.getFactory(props);
name = factory.getClass().getName();
if(logging) Logger.LOG(CLASS_NAME, METHOD_NAME, "Factory of type ["+name+"] created. "+factory, Logger.LOGGER_INFO);
} catch (CSFactoryInitializationException fie) {
Logger.LOG(CLASS_NAME, METHOD_NAME,fie, Logger.LOGGER_ERROR);
}
Logger.LOG(CLASS_NAME,METHOD_NAME, "BAL!!! "+factory.getConfigProperties(),Logger.LOGGER_INFO);
try{
// create the client object
if(logging) Logger.LOG(CLASS_NAME, METHOD_NAME, "Getting client with username: ["+username+"], password: ["+password+"] and role: ["+role+"]", Logger.LOGGER_INFO);
Logger.LOG(CLASS_NAME,METHOD_NAME,"LOCALE! "+Locale.getDefault(), Logger.LOGGER_INFO);

client = factory.getClient(username, role, password, Locale.getDefault(), "mydemo",null);

if(logging) Logger.LOG(CLASS_NAME, METHOD_NAME, "Got client: ["+client+"]", Logger.LOGGER_INFO);

if(logging) Logger.LOG(CLASS_NAME, METHOD_NAME, "[Exit]", Logger.LOGGER_INFO);


}
catch (Exception e){
Logger.LOG(CLASS_NAME, METHOD_NAME, "ERROR!!!"+e ,Logger.LOGGER_INFO );
}

After some decompiling I am still no closer to a solution, but I can tell you that the ACCESS element inside of the AxisFactoryAdapterImpl is null, after the factory is created.

Calls to get serverversion() in the factory also throw a null pointer exception.

There is a path in the code I can where an exception could happen that could possibly cause this to occurr(I believe) (a factory being returned even though it was not properly instantiated), but that path that I have found so far only could happen if a malformedurlexception occurs in the axisfactory instantiator, where it catches this exception, initializes a CSFactoryInitializationException and sets its root cause, but then NEVER throws the exception:


public AxisFactory(Props){

.
.
.
try{

do some things
}
catch (MalformedURLException e) {
CSFactoryInitializationException n = new CSFactoryInitializationException("serviceBaseURL or accessBaseURL was malformed.");

n.setRootCause(e);
} catch (ServiceException e) {
CSFactoryInitializationException n = new CSFactoryInitializationException("Service exception:" + e.getMessage());

throw n;
}

So if I am reading this case right, I can see the malformedURLExceptioin causing a case where the instianitiation code did not complete, but a factory object is returned anyway and no exception was thrown.

This would be a happy day for me, but the URL being passed into the accessfactory as part of its props parameter is not malformed. However there is ZERO doubt that the instantiation did not complete properly, the internal element this.access in the axisFactory that is returned to be is clearly null...

GetClient, GetServerVersion and GetOSType all fail with NULL POINTER EXCEPTION when called with the FactoryObject the getFactory creates, and all three methods are little more than

return this.access.xxxxx

The factory is successfully returning from creation, even though it clearly did not properly instiatiate, and the one case I can see in the code where this could happen, doesn't make sense as the URL passed in property "serviceBaseURL" is simply http://servername:80 which is NOT a malformed URL.

Any help on this would be appreciated, and If someone at Interwoven is looking at this, it appears that there is clearly a bug in the AXISFACTORY class in your CSSDK client code for Java 1.4.
