However when I try to access it with dependency injection (#Resource) in a stateless container it works fine.
Thank you in advance.
P. S. The original exception was ThrowableArtifact cannot be cast to java.lang.Error but this seems to be a bug so I debugged it to get the NoSuchMethodException.

Error while intercepting a hibernate event

My goal is to find out what columns where changed during an update on my MySQL database.
My first idea was to use the Hibernate Event System. I have implemented a PreUpdateEventListener. The event allows access to the changed object and I'm retrieving the older object from the database. I am using the Java Object Diff Library to compare the two objects. Since I only need the first layer to be compared I configured the Comparator as follows:
public static List<String> compareTillFirstLayer(Object pre, Object post) {
ArrayList<String> changedProperties = new ArrayList<String>();
InclusionResolver inclusionResolver = new InclusionResolver() {
#Override
public Inclusion getInclusion(DiffNode node) {
if (node.getParentNode().isRootNode()) {
return Inclusion.INCLUDED;
}
return null;
}
#Override
public boolean enablesStrictIncludeMode() {
return true;
}
};
ObjectDiffer objectDiffer = ObjectDifferBuilder.startBuilding().inclusion().resolveUsing(inclusionResolver)
.and().build();
DiffNode root = objectDiffer.compare(pre, post);
root.visitChildren(new DiffNode.Visitor() {
#Override
public void node(DiffNode node, Visit visit) {
changedProperties.add(node.getPropertyName());
}
});
return changedProperties;
}
This returns the changed properties of the object. To find the connection to the database columns I use the Hibernate Configuration and it's mapping like this:
for (String property : changedProperties) {
PersistentClass persistentClass = HibernateUtil.getHibernateUtil().getConfiguration()
.getClassMapping(Consumer.class.getName());
String columnName = ((Column) persistentClass.getProperty(property).getColumnIterator().next())
.getName();
System.out.println(columnName);
}
This workes just fine for my Consumer object but it fails with other objects like an Appointment or a Vehicle object.
Even the exceptions differ from object to object.
If I try to monitor the changes of the Appointment I recieve the following exception:

I really don't know where to start on this one since the exceptions are so different from eachother. Any tips on what might cause this behaviour are appreciated!
If any further information is needed I'll provide it.
Edit: The Vehicle error is kind of resolved. It was due to a missing feature in the before mentioned Java Object Diff Library. Source I am currently working on a workaround for excluding arrays from the comparison
The first part of the question is answered. Due to the Java Object Diff Library not beeing able to work with arrays I decided to just exclude these from the comparison.
This works just fine with the rewritten compareTillFirstLayer method like this:
public class HibernateEventObjectComparator {
public final static InclusionResolver inclusionResolver = new InclusionResolver() {
#Override
public Inclusion getInclusion(DiffNode node) {
if (node.getParentNode().isRootNode() && node.getValueType().isArray()) {
return Inclusion.EXCLUDED;
} else if (node.getParentNode().isRootNode()) {
return Inclusion.INCLUDED;
} else {
return null;
}
}
#Override
public boolean enablesStrictIncludeMode() {
return true;
}
};
public static List<String> compareTillFirstLayer(Object pre, Object post) {
ArrayList<String> changedProperties = new ArrayList<String>();
ObjectDiffer objectDiffer = ObjectDifferBuilder.startBuilding().inclusion().resolveUsing(inclusionResolver)
.and().build();
DiffNode root = objectDiffer.compare(pre, post);
root.visitChildren(new DiffNode.Visitor() {
#Override
public void node(DiffNode node, Visit visit) {
changedProperties.add(node.getPropertyName());
}
});
return changedProperties;
}
...
EDIT: The second problme is solved as well.
The list of columns I got from hibernate was empty if it referred to a collection. Since I didn't need these columns I'm simply checking if a column is availabe and only iterate over the columns array if there are columns inside. Sadly I have no answer to why the columns array for any collection is empty.

I have searched for long.. Most of answers were about setting up a default constructor. But in my case, the file doesnt have a default constructor. I may be looking at this completely wrong.. So here's hoping some one can help me out..
Thanks in advance :)
Code:
#RequestMapping(value="/retrieve", method=RequestMethod.POST)
public ArrayList<String> listFiles() {
ArrayList<String> listOfFiles =new ArrayList<String>() ;
File folder = new File("E:/uploadedFiles/");
File[] files = folder.listFiles();
for (File file : files) {
if (file.isFile()) {
System.out.println(file.getName());
listOfFiles.add(file.getName());
}
}
return listOfFiles;
}

Compiling JUnit tests at runtime: "No runnable methods"

I want to compile and run JUnit (4.12) tests at runtime within a grails (2.4.4) project.
The following string is an example for such a test (classname: "DasS").
import org.junit.runner.JUnitCore;
import static org.junit.Assert.*;
import org.junit.Before;import org.junit.Test;
import org.junit.After;
public class DasS {
public DasS(){}
#Before
public void setUp() {}
#After
public void tearDown(){}
#Test
public void test0() {
assertEquals(new Integer(1),new Integer(1));
}
#Test
public void test1() {
assertEquals(new Double(1),new Double(1));
}
}
The purpose of the following method is to load in the classes and run the compiled tests.
public void run() {
URLClassLoader loader = (URLClassLoader) getClass().getClassLoader();
DynamicClassLoader dynamicLoader = new DynamicClassLoader(loader);
try {
dynamicLoader.addURL(new File(Configure.TMP_FOLDER).toURI().toURL());
} catch (MalformedURLException e1) {
//Add good exception handling here
}
try {
dynamicLoader.loadClass("DasS");
} catch (ClassNotFoundException e2) {
// TODO Auto-generated catch block
e2.printStackTrace();
}
Class testClass2 = null;
try {
testClass2 = Class.forName("DasS", true, dynamicLoader);
} catch (ClassNotFoundException e2) {
// TODO Auto-generated catch block
e2.printStackTrace();
}
Result result2 = JUnitCore.runClasses(testClass2);
for(Failure f : result2.getFailures()) {
System.out.println(f.getMessage());
}
}
There are no errors during the compilation nor during the loading of the classes, but every time I run this code I get "No runnable methods" as a failure message, although there are obviously some test-methods.

If I just copy-paste your test class (DasS) into a new class in Android Studio (path must be correct), then the 2 tests run successfully for me.
The test runner selected on the UI is:
android.support.test.runner.AndroidJUnitRunner
I do not need you helper method (public void run())
The dependencies in your project might be different. You might need a subset of mine:
dependencies {
compile 'com.android.support:support-annotations:22.2.0'
androidTestCompile 'com.google.dexmaker:dexmaker:1.2'
androidTestCompile 'com.android.support.test:runner:0.4.1'
androidTestCompile 'com.android.support.test:rules:0.3'
androidTestCompile 'junit:junit:4.12'
}
But you might need to set the correct test runner (still in build.gradle):
defaultConfig {
minSdkVersion 19
targetSdkVersion 22
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

The column dataType has char(8) as it's data type.
I have tried both rs.getString() and rs.getCharecterStream() where rs is the ResultSet obtained from this query.I think this has no effect on the problem because the error occurs before this line is even reached.
This is a description of myTable
This is my code:
public ArrayList<ScenarioFieldInfo> getScreenFields(String objType, String scenarioType)
{
System.out.println("Input args objType: "+objType+" and scenarioType: "+scenarioType);
PreparedStatement pst = null;
ResultSet rs = null;
ArrayList<ScenarioFieldInfo> scenarioFieldList = new ArrayList<ScenarioFieldInfo>();
try {
String sql = "select * from myTable where objtype='"+objType+"' and scnrtype='"+scenarioType+"'";
System.out.println(sql);
pst = (PreparedStatement) conn.prepareStatement(sql.toString());
rs = pst.executeQuery();
while(rs.next()){
ScenarioFieldInfo fieldInfo = new ScenarioFieldInfo();
fieldInfo.fieldName = rs.getString("fieldName");
fieldInfo.fieldLabel = rs.getString("FieldLabel");
//fieldInfo.sapType=rs.getString("dataType");
BufferedReader reader=new BufferedReader(rs.getCharacterStream("dataType"));
try {
String sapType=reader.readLine();
fieldInfo.sapType=sapType;
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
fieldInfo.parameter=rs.getString("PARAMETER");
scenarioFieldList.add(fieldInfo);
}
System.out.println("There are "+scenarioFieldList.size()+" screen fields");
} catch (SQLException e) {
e.printStackTrace();
}
finally
{
close(rs);
close(pst);
}
return scenarioFieldList;
}
I found that the code was crashing because I had getCharecterStream instead of getString which was causing an error in my case.Modiying the code to:
rs.getString("dataType");
fixed the issue
