Validation of XML by XSD Schema(s) with Error Handler

The paths to the schemas (/path/to/schema1) must be in the order of dependency (schema2 need schema1 ---> import schema1, import schema2)

      public boolean isXmlXsdValid(String sourceXml) {  
                JAXBContext context = JAXBContext  
                          .newInstance(package.path.to.generated.sources.ObjectFactory.class,  
                                    package.path.to.generated.sources2.ObjectFactory.class);  
                Unmarshaller unmarshaller = context.createUnmarshaller();  
                SchemaFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);  
                unmarshaller.setSchema(schemaFactory.newSchema(new Source[] {  
                          new StreamSource(XMLHelper.class.getResourceAsStream("/path/to/schema1")),  
                          new StreamSource(XMLHelper.class.getResourceAsStream("/path/to/schema2")),  
                          new StreamSource(XMLHelper.class.getResourceAsStream("/path/to/schema3")),  
                }));  
                unmarshaller.setEventHandler(new ValidationEventHandler() {  
                     @Override  
                     public boolean handleEvent(ValidationEvent event) {  
                          LOG.info("\nEVENT");  
                          LOG.info("SEVERITY: {}", event.getSeverity());  
                          LOG.info("MESSAGE: {}", event.getMessage());  
                          LOG.info("LINKED EXCEPTION: {}", event.getLinkedException());  
                          LOG.info("LOCATOR");  
                          LOG.info("  LINE NUMBER: {}", event.getLocator().getLineNumber());  
                          LOG.info("  COLUMN NUMBER: {}", event.getLocator().getColumnNumber());  
                          LOG.info("  OFFSET: {}", event.getLocator().getOffset());  
                          LOG.info("  OBJECT: {}", event.getLocator().getObject());  
                          LOG.info("  NODE: {}", event.getLocator().getNode());  
                          LOG.info("  URL: {}", event.getLocator().getURL());  
                          return true;  
                     }  
                });  
                unmarshaller.unmarshal(new StringReader(sourceXml));  
                return true;  
           } catch (SAXException e) {  
                LOG.error("While trying to validate the xml, caught a SAXException ", e);  
           } catch (JAXBException e) {  
                LOG.error("While trying to validate the xml, caught an JAXBException ", e);  
           }  
      }  

How to create a simple Java Builder with help of Notepad ++ regexp

1. copy member:

private int id;
private String comment;
private String targetId;
private String targetName;
private String targetSource;
private String tool;
private String action;
private Date time;

2. Run this Search/Replace in Notepad++
Search:

\S+ (\S+) (\S)(\S+);

Replace:

public LogActionBuilder \2\3 \(\1 \2\3\) { this.logAction.set\U\2\E\3\(\2\3\); return this;}

Create a nice and fluent builder:

public LogActionBuilder id(int id) {
this.logAction.setId(id);
return this;
}

public LogActionBuilder comment(String comment) {
this.logAction.setComment(comment);
return this;
}
