NoClassDefFoundError when trying to initialize ehcache via XML file

I have randomly this problem when I try to initialize ehcache:

The weird behavior is that if I restarted the container (weblogic), it works fine. This is the class I use to initialize the cache, trimming down to the bare essential:
import javax.annotation.PostConstruct;
import javax.cache.CacheManager;
import javax.cache.Caching;
import javax.enterprise.context.ApplicationScoped;
import lombok.Getter;
import lombok.extern.slf4j.Slf4j;
#Slf4j
#ApplicationScoped
public class CacheManagerServiceBean {
private static final String EHCACHE_CONFIG_FILE_PATH = "/ehcache.xml";
#Getter
private CacheManager cacheManager = null;
#Getter
private boolean cacheEnabled = false;
#PostConstruct
private void initialize() {
logger.info("Instantiating cache manager");
try {
this.cacheManager = Caching.getCachingProvider().getCacheManager(
getClass().getResource(EHCACHE_CONFIG_FILE_PATH).toURI(),
getClass().getClassLoader());
cacheEnabled = true;
} catch (Exception|NoClassDefFoundError e) {
logger.error("Unable to enable cache", e);
}
}
}
I tried to add the following line
<wls:package-name>net.sf.saxon.*</wls:package-name>
to /META-INF/weblogic-application.xml, but this did't help. Saxon is a direct dependancy of the module:
<dependency>
<groupId>net.sf.saxon</groupId>
<artifactId>Saxon-HE</artifactId>
<version>9.5.1-8</version>
</dependency>
The module is packaged as jar in a ear multimodule application.
Does anybody have any idea on how to make sure that the class XPathException is always found by saxon? Thank you in advance.

Problems like this are usually caused by having several different versions of Saxon on the classpath at the same time.

java.lang.ClassFormatError: Absent Code attribute in method that is not native or abstract in class file javax/jms/JMSException

im getting the below issue when i run junit test cases, the class is as follow:;
public class RoeSubmissionBeanTest {
RoeSubmissionBean roeSubmissionBean;
ServiceActivation serviceAct = new ServiceActivation();
UpdateTimeResponse updateTimeResponse = new UpdateTimeResponse();
RoEUpdateSuccessfulDT roeUpdateSucces;
MessageIdentification msgID;
ExchangeFaultData faultMessage;
#Before
public void setUp() throws Exception {
//it failes on this line
roeSubmissionBean = Mockito.mock(RoeSubmissionBean.class);
serviceAct = Mockito.mock(ServiceActivation.class);
updateTimeResponse = Mockito.mock(UpdateTimeResponse.class);
roeUpdateSucces = Mockito.mock(RoEUpdateSuccessfulDT.class);
doCallRealMethod().when(roeSubmissionBean).sendMessage(roeUpdateSucces, msgID, faultMessage);
}
and the main methods is
public class RoeSubmissionBean {
private Logger logger = LoggerFactory.getLogger(RoeSubmissionBean.class);
private JMSSender sender = new JMSSender(RoeSubmissionBean.class);
}
i tried some questions here that i have to put dependency in POM, but still getting same error

Compiling java with Janino (broken Classpath)

I Am trying to compile very simple class with Janino:
import org.codehaus.commons.compiler.CompileException;
import org.codehaus.janino.ClassBodyEvaluator;
import java.io.IOException;
import java.io.StringReader;
public class JaninoTest{
public static void main(String[] args) throws IOException, CompileException {
String sampleClass =
"public class Test {" +
"public void sampleMethod() {\n" +
" JsonObject obj = new JsonObject();\n" +
" obj.add(\"p1\", new JsonPrimitive(2));\n" +
" System.out.println(obj.get(\"p1\"));\n" +
"}" +
"}";
ClassBodyEvaluator classBodyEvaluator = new ClassBodyEvaluator();
classBodyEvaluator.setParentClassLoader(Thread.currentThread().getContextClassLoader());
classBodyEvaluator.setDefaultImports(new String[] { "com.google.gson.JsonObject",
"com.google.gson.JsonPrimitive"});
StringReader sr = new StringReader(sampleClass);
classBodyEvaluator.cook(null, sr);
Class<?> clazz = classBodyEvaluator.getClazz();
System.out.println(clazz.getName());
}
}
Every things works fine here, but org.codehaus.janino.ClassBodyEvaluator compiler have limitation to Java 5.
So I read on Janino website that you can change compiler to overcome this limitation
JANINO can be configured to use javax.tools.JavaCompiler, i.e. JAVAC,
which removes the Java 5-related limitations.
So I changed ClassBodyEvaluator on this one org.codehaus.commons.compiler.jdk.ClassBodyEvaluator; which is also available on Janino website and AFAIK don't have Java 5 limitation.
But unfortunately it throws following stack trace:

This probably has something to do with compiler classpath but I don't see any method in API to somehow manipulate it.
I will be grateful for any suggestions

Works for me.

Here is teh codez, line 44 is the one doing the lookup:
package com.example;
import java.util.Properties;
import javax.naming.InitialContext;
import javax.naming.NamingException;
public class ShoppingBasketServiceClient {
public static void main(String[] args) throws NamingException {
Properties props = new Properties();
props.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
props.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
props.setProperty("java.naming.provider.url", "jnp://localhost:1099");
String Lookup = "ejb/ShoppingBasketService/remote";
try {
InitialContext ic = new InitialContext(props);
// ShoppingBasketServiceRemote shoppingBasketService = (ShoppingBasketServiceRemote) ic.lookup(Lookup);
Object shoppingBasketService = (Object) ic.lookup(Lookup);
} catch (NamingException e) {
System.out.println("Exception:" + e);
}
}
}
I'm confused as to why it's looking for a Log class (and why the exception is not package-qualified)?
ShoppingBasketServiceRemote is just an interface that imports the javax.ejb.Remote annotation and extends another interface - neither make any reference to a Log class? Additionally, you'll see my example only casts the result to Object (but the result is the same if I swap out for the service interface)?

ShoppingBasketServiceRemote is just an interface that imports the
javax.ejb.Remote annotation and extends another interface - neither
make any reference to a Log class?
Examine all the objects referenced in the interface & their
transitive dependencies. Something will point to the "Log" class.
Also check the remote server for errors, maybe the error is on the
remote server
Try doing a simple
Class.forName("ShoppingBasketServiceRemote") - you might see it failing with the same error.
Additionally, you'll see my example only casts the result to Object
(but the result is the same if I swap out for the service interface)?
Casting the object happens after your jvm is able to load the object returned by ic.lookup(Lookup) - so the error will happen whether you cast or not.

How to use Genson provider as default in Jersey client?

I have simple client based on Jersey framework.
I want to use Genson as default JSON provider.
Firstly I created some class which implemented ContextResolver:
#Provider
public class GensonCustomResolver implements ContextResolver<Genson> {
private final Genson genson = new Genson.Builder().setSkipNull(true).setDateFormat(new UtcDateFormat()).create();
#Override
public Genson getContext(Class<?> type) {
return genson;
}
}
And UtcDateFormat class:
public class UtcDateFormat extends DateFormat {
#Override
public StringBuffer format(Date date, StringBuffer toAppendTo, FieldPosition fieldPosition) {
return new StringBuffer("" + date.getTime());
}
#Override
public Date parse(String source, ParsePosition pos) {
return new Date(Long.parseLong(source));
}
}
Then I used this:
ClientConfig cfg = new DefaultClientConfig(GensonCustomResolver.class);
Client client = Client.create(cfg);
Integer meetingId = 1;
Meeting result = client.resource("http://mywebservise.com/").path("meeting")
.path(meetingId.toString()).get(ClientResponse.class).getEntity(Meeting.class);
But, it failed. Here are log:

What's wrong?
P.S. Jersey client 1.8
Genson 0.98

You should upgrade to the latest Genson version, there have been some improvements and providing a custom instance to jersey is easier.
In the newer versions, Genson will automatically detect if the input is the time in millis or a date string and deser it accordingly.
The dateformat registered with useDateFormat(...) will be used during deserialization, but this will also serialize the dates as strings. If you want to serialize them as a long (which is the default in the newever versions), you have define it with useDateAsTimestamp(true).
I hope this makes things a bit more clear. You can have a look at the config options for more details.
