JDeveloper don't find SignerEPES having xades4j.jar

Im using #lgoncalves code to sign an XML with XADES4J EPES. But however jdeveloper don't find (SignerEPES) when I have the xades4j.jar on my classpath. I let you the image of my library and the code:
Project Library
private static void signBes(Document doc) throws XadesProfileResolutionException, XAdES4jException,
KeyStoreException {
//Document doc = getTestDocument();
Element elemToSign = doc.getDocumentElement();
SignaturePolicyInfoProvider policyInfoProvider = new SignaturePolicyInfoProvider()
{
#Override
public SignaturePolicyBase getSignaturePolicy()
{
return new SignaturePolicyIdentifierProperty(
new ObjectIdentifier("oid:/1.2.4.0.9.4.5", IdentifierType.OIDAsURI, "Policy description"),
new ByteArrayInputStream("Test policy input stream".getBytes()))
.withLocationUrl(""); //<- I really don't know what to put right here.
}
};
KeyingDataProvider kdp = new FileSystemKeyStoreKeyingDataProvider("pkcs12","C:/****/****.pfx",new FirstCertificateSelector(),new DirectPasswordProvider("****"),new DirectPasswordProvider("****"),true);
SignerEPES signer = (SignerEPES) new XadesEpesSigningProfile(kdp, policyInfoProvider).newSigner();
new Enveloped(signer).sign(elemToSign);
}
Link to the sample code on GitHub: https://github.com/luisgoncalves/xades4j/blob/master/src/test/java/xades4j/production/SignerEPESTest.java
EDIT:
I tried to force the import like (import xades4j.production.SignerEPES) but IDE says "Cannot be accessed from outside package" but really don't know what that means

SignerEPES is a package-private class, so application code won't be able to import it. The tests use it just to be sure that the proper type is being returned.
In your code you can just use XadesSigner as the type of your variable.

Get file from class path so tests can run on all machines

I am using Vertx and trying to test some parameters that i am getting data from jsonfile, currently it works but i want get this file just through class path so it can be tested from a different computer.
private ConfigRetriever getConfigRetriever() {
ConfigStoreOptions fileStore = new ConfigStoreOptions().setType("file").setOptional(true)
.setConfig(new JsonObject()
.put("path", "/home/user/MyProjects/MicroserviceBoilerPlate/src/test/resources/local_file.json"));
ConfigStoreOptions sysPropsStore = new ConfigStoreOptions().setType("sys");
ConfigRetrieverOptions options = new ConfigRetrieverOptions().addStore(fileStore).addStore(sysPropsStore);
return ConfigRetriever.create(Vertx.vertx(), options);
}
My path as written above starts from /home / dir which makes it impossible to be tested on another machine. My test below uses this config
#Test
public void tourTypes() {
ConfigRetriever retriever = getConfigRetriever();
retriever.getConfig(ar -> {
if (ar.failed()) {
// Failed to retrieve the configuration
} else {
JsonObject config = ar.result();
List<String> extractedIds = YubiParserServiceCustomImplTest.getQueryParameters(config, "tourTypes");
assertEquals(asList("1", "2", "3", "6"), extractedIds);
}
});
}
I want to make the path a class path so i can test it on all environment.
I tried to access class path like this but not sure how it should be
private void fileFinder() {
Path p1 = Paths.get("/test/resources/local_file.json");
Path fileName = p1.getFileName();
}

If you have stored the file inside "src/test/resources" then you can use
InputStream confFile = getClass().getResourceAsStream("/local_file.json");
or
URL url = getClass().getResource("/local_file.json");
inside your test class (example)
IMPORTANT!
In both cases the file names can start with a / or not. If it does, it starts at the root of the classpath. If not, it starts at the package of the class on which the method is called.

Put .json file to /resources folder of your project (here an example).
Then access it via ClassLoader.getResourceAsStream:
InputStream configFile = ClassLoader.getResourceAsStream("path/to/file.json");
JsonObject config = new JsonParser().parse(configFile);
// Then provide this config to Vertx

As I understand, considering the location of your json file, you simply need to do this:
.setConfig(new JsonObject().put("path", "local_file.json"));

Read XSD using org.eclipse.xsd.util.XSDResourceImpl

I successfully read an XSD schema using org.eclipse.xsd.util.XSDResourceImpl and process all contained XSD elements, types, attributes etc.
But when I want to process a reference to an element declared in the imported schema, I get null as its type. It seems the imported schemas are not processed by XSDResourceImpl.
Any idea?
final XSDResourceImpl rsrc = new XSDResourceImpl(URI.createFileURI(xsdFileWithPath));
rsrc.load(new HashMap());
final XSDSchema schema = rsrc.getSchema();
...
if (elem.isElementDeclarationReference()){ //element ref
elem = elem.getResolvedElementDeclaration();
}
XSDTypeDefinition tdef = elem.getType(); //null for element ref
Update:
I made the imported XSD invalid, but get no exception. It means it is really not parsed. Is there any way to force loading imported XSD together with the main one?

There is one important trick to process imports and includes automatically. You have to use a ResourceSet to read the main XSD file.
import org.eclipse.emf.ecore.resource.Resource;
import org.eclipse.emf.ecore.resource.ResourceSet;
import org.eclipse.emf.ecore.resource.impl.ResourceSetImpl;
import org.eclipse.xsd.util.XSDResourceFactoryImpl;
import org.eclipse.xsd.util.XSDResourceImpl;
import org.eclipse.xsd.XSDSchema;
static ResourceSet resourceSet;
XSDResourceFactoryImpl rf = new XSDResourceFactoryImpl();
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put("xsd", rf);
resourceSet = new ResourceSetImpl();
resourceSet.getLoadOptions().put(XSDResourceImpl.XSD_TRACK_LOCATION, Boolean.TRUE);
XSDResourceImpl rsrc = (XSDResourceImpl)(resourceSet.getResource(uri, true));
XSDSchema sch = rsrc.getSchema();
Then before processing an element, an attribute or a model group you have to use this:
elem = elem.getResolvedElementDeclaration();
attr = attr.getResolvedAttributeDeclaration();
grpdef = grpdef.getResolvedModelGroupDefinition();

Could you try something like that, manually resolve type :
final XSDResourceImpl rsrc = new XSDResourceImpl(URI.createFileURI(xsdFileWithPath));
rsrc.load(new HashMap());
final XSDSchema schema = rsrc.getSchema();
for (Object content : schema.getContents())
{
if (content instanceof XSDImport)
{
XSDImport xsdImport = (XSDImport) content;
xsdImport.resolveTypeDefinition(xsdImport.getNamespace(), "");
}
}

You may have a look here. Particulary in this method :
private static void forceImport(XSDSchemaImpl schema) {
if (schema != null) {
for (XSDSchemaContent content: schema.getContents()) {
if (content instanceof XSDImportImpl) {
XSDImportImpl importDirective = (XSDImportImpl)content;
schema.resolveSchema(importDirective.getNamespace());
}
}
}
}

Tomcat 8 new Resource implementation to map Jar files in a separate directory

With tomcat 8 I have extend the WebAppClassLoader and add some jar filed from a shared location to the classloader path using addRepository() method. With tomcat 8 addRepository have been removed and new resource implementation have been introduced. I'm still able to use the addUrl method to add jar files. But I would like to implement the new resource based implementation.
I've tried with
DirResourceSet dirResourceSet = new DirResourceSet(getContext().getResources(), "/WEB-INF/lib", "/home/thusitha/lib/runtimes/cxf", "/");
WebResourceRoot webResourceRoot = getContext().getResources();
webResourceRoot.getContext().getResources().addPreResources(dirResourceSet);
But this is not working and still it throws classnotfoundexception
Can someone tell me how to map a directory which contains jars to a particular webapp using Tomcat new resource implementation?

A solution to this problem is to register your resources by overriding the ContextConfig class (org.apache.catalina.startup.ContextConfig). Catalina enters a starting state immediately after it scans your document path for resources. Most of the processing of those resources, such as annotations, is handled by the ContextConfig LifecycleListener. To ensure the resources are added before the context configuration takes place, override the ContextConfig.
final Context currentContext = ctx;
ContextConfig ctxCfg = new ContextConfig() {
#Override
public void lifecycleEvent(LifecycleEvent event) {
if (event.getType().equals(Lifecycle.CONFIGURE_START_EVENT)) {
WebResourceRoot webResourcesRoot = currentContext.getResources();
String baseDir = Platform.getBaseDir(); // Server Base Directory
File libDir = new File(baseDir + File.separator + "lib");
DirResourceSet dirResourceSet = null;
try {
dirResourceSet = new DirResourceSet(webResourcesRoot, "/WEB-INF/lib", libDir.getCanonicalPath(), "/");
} catch (IOException e) {
throw new RuntimeException(e);
}
webResourcesRoot.addPostResources(dirResourceSet);
String[] possibleJars = dirResourceSet.list("/WEB-INF/lib");
for(String libfile : possibleJars) {
WebResource possibleJar = dirResourceSet.getResource("/WEB-INF/lib/"+libfile);
System.err.println(String.format("Loading possible jar %s",possibleJar.getCanonicalPath())); // Just checking...
if (possibleJar.isFile() && possibleJar.getName().endsWith(".jar")) {
WebResourceSet resourceSet = new JarResourceSet(webResourcesRoot, "/WEB-INF/classes", possibleJar.getCanonicalPath(),"/");
webResourcesRoot.addPostResources(resourceSet);
}
}
}
super.lifecycleEvent(event);
}
};
ctx.addLifecycleListener(ctxCfg);
This is an undocumented solution that works on Tomcat 8.0.23. Considering the complexity and difficulty of this I can't say it is a better solution than adding jars directly to ClassLoaders.

Embedded jetty ServletTester serving single static file

I'm unit testing with jetty and I want to serve not only my servlet under test but a static page as well. The static page is needed by my application. I'm initializing jetty like this
tester = new ServletTester();
tester.setContextPath("/context");
tester.addServlet(MyServlet.class, "/servlet/*");
tester.start();
What I need now, is something like
tester.addStaticPage("local/path/in/my/workspace", "/as/remote/file");
Is this possible with jetty?

I don't think you can do this with ServletTester. ServletTester creates a single Context for the servlet. You need to set up embedded jetty with at least two contexts: one for the servlet, and one for the static content.
If there was a full WebAppContext, you'd be set, but there isn't.
You could make a copy of ServletTester and add hair, or you can just read up on the API and configure the necessary contexts. Here's a code fragment to show you the basic idea, you will
not be able to compile this as-is. You will need to create a suitable context for the static content.
server = new Server();
int port = Integer.parseInt(portNumber);
if (connector == null) {
connector = createConnector(port);
}
server.addConnector(connector);
for (Webapp webapp : webapps) {
File sourceDirFile = new File(webapp.getWebappSourceDirectory());
WebAppContext wac = new WebAppContext(sourceDirFile.getCanonicalPath(), webapp.getContextPath());
WebAppClassLoader loader = new WebAppClassLoader(wac);
if (webapp.getLibDirectory() != null) {
Resource r = Resource.newResource(webapp.getLibDirectory());
loader.addJars(r);
}
if (webapp.getClasspathEntries() != null) {
for (String dir : webapp.getClasspathEntries()) {
loader.addClassPath(dir);
}
}
wac.setClassLoader(loader);
server.addHandler(wac);
}
server.start();

Set the resource base to the directory containing your static content, and add the jetty "default servlet" to serve that content. I have added the appropriate code to your example below.
tester = new ServletTester();
tester.setContextPath("/context");
tester.setResourceBase("/path/to/your/content");
tester.addServlet(MyServlet.class, "/servlet/*");
tester.addServlet(org.eclipse.jetty.servlet.DefaultServlet.class, "/*");
tester.start();
