JaxpContext Error when executing API request

Nexica — Wed, 04 Jun 2025 15:22:48 GMT

Hello,

Could you help on this error plz?

when trying to send a request i get this:

Caused by: java.lang.IllegalStateException: Unable to determine StAX implementation: class __redirected.__XMLInputFactory
	at com.netapp.nmsdk.common.xml.JaxpContext$Stax.detectStaxImplementation(JaxpContext.java:161)
	at com.netapp.nmsdk.common.xml.JaxpContext$Stax.<init>(JaxpContext.java:70)
	at com.netapp.nmsdk.common.xml.JaxpContext$Stax.<init>(JaxpContext.java:44)
	at com.netapp.nmsdk.common.xml.JaxpContext.<clinit>(JaxpContext.java:35)

After trying again, the error changes and i get this:

Caused by: java.lang.NoClassDefFoundError: Could not initialize class com.netapp.nmsdk.common.xml.JaxpContext
	at com.netapp.nmsdk.client.XmlApiInvocation.writeRequest(XmlApiInvocation.java:81)

	at com.netapp.nmsdk.client.ApiIteratorSupport$ApiIterator.hasNext(ApiIteratorSupport.java:102)

the JaxpContext is there (in com.netapp.nmsdk.client) but i dont have the source code to check what it needs.

Can you list the necessary dependencies to other libraries? I am curretnly using the following.

nmsdk-runtime 5.6

ontap-api 8.3.1

commons-lang 2.6

commons-io 2.4

commons-codec 1.8

Thank you!

We investigated and found the problem:

This is happening when using WildFly 10.1.0 Final, which uses a Proxy Implementation of WOODSTOX and cannot be detected as a valid implementation of StaxImplementation in JaxpContext. The problem lies on these lines:

public static enum StaxImplementation {
            WOODSTOX{

                @Override
                boolean isInstance(XMLInputFactory xmlInputFactory) {
                    try {
                        return Class.forName("com.ctc.wstx.stax.WstxInputFactory", true, Thread.currentThread().getContextClassLoader()).isInstance(xmlInputFactory);
                    }
                    catch (ClassNotFoundException e) {
                        return false;
                    }
                }

And the solution we tried is this one:

public static enum StaxImplementation {
			WOODSTOX {

				@Override
				boolean isInstance(XMLInputFactory xmlInputFactory) {
					try {

						try {
							if ((xmlInputFactory.getProperty("org.codehaus.stax2.implVersion") == null)) {
								return Class.forName("com.ctc.wstx.stax.WstxInputFactory",true,
                                                                                            Thread.currentThread().getContextClassLoader())
										.isInstance(xmlInputFactory);
							}
						} catch (IllegalArgumentException e) {
							return Class.forName("com.ctc.wstx.stax.WstxInputFactory", true,
									Thread.currentThread().getContextClassLoader()).isInstance(xmlInputFactory);
						}

						return true;
					} catch (ClassNotFoundException e) {
						return false;
					}
				}

We would appreciate if you could solve this issue in the next release.

Thank you
