[validator] EmailValidator 1.4.1 returns true for some invalid(?) email addresses

The isValid routine was changed in version 1.4.1 and now
returns true for email addresses like these:

user <at> com

user <at> gmail

Are these valid email address forms?

[Imaging] a quick resize sample needed

Hi Gurus,

Quite a silly question this is. But I really worked for one whole day but still could not get any result.

I have below codes. I just want to finish a a simple function to resize the original picture. But I don't know
how to set  its param.. 
I tried to read the doc API and read the test code. But I still could not figure it out how to do..

Can you plz do me a favor? Looking forward to your early reply...

public class ApacheCommonImaging {
public static void main(String[] args) {
// TODO Auto-generated method stub

File someFile = new File("E:\\deleteMe\\image\\original.jpg");
File file = someFile;
BufferedImage image_3 = Sanselan.getBufferedImage(file);
File destination = new File("E:\\deleteMe\\image\\commonImaging\\destination.jpg");
ImageFormat format1 = ImageFormat.IMAGE_FORMAT_JPEG;
Map params = new HashMap(Object, Object);   //????
Map params = new HashMap(JpegImageParser.TIFF_TAG_IMAGE_LENGTH, new TagInfo()); //????
Sanselan.writeImage(image_3, destination, format1, params);

catch (Exception e)

[jexl]Apache JEXL conditional execution path

I am using Apache JEXL for condition expression execution.

My expression can be like

(functionA(string[]) || functionB(string[])) &&  (functionC(string[]) ||  functionD(string[]) )
Each function will return some string. If the function returns empty string, then it consider as false.

At the end I need to have concatenated string and also which path has created the concatenated string.

(functionA(string[]) && functionB(string[])) ||  (functionC(string[]) &&  functionD(string[]) )
If functionA = true, functionB = false, functionC = true, functionD = true Final output should be of
concatenated string from functionC and functionD. It should not contain functionA output.

Any suggestion on how to do it?

Re: Re: [scxml] bug with script in combination of a chain of transitions

Hi Woonsan, hi others, 

At first, sorry for the late reply. I posted the issue in april, but didn't get a response in the first two
weeks. Then I forgot about it (busy with other issues), and then just saw your reply, about a week ago. 

Anyway, I've been thinking hard about the issue, and I think I now understand what is going on here. 

Then again, sorry that my example wasn't so clear, at first. The problem is we're having very complicated
scxml schemes working with several custom classes, and I tried to bring the example back to the basics, but
probably just missed the key thing. 

It basically comes to this, I discovered. Consider this scxml: 

<state id="bla">
       <transition event="screening" target="cxr" />

<state id="cxr">
                 <ntd:test id="CXR" />
        <transition event="CXR.negative" target="untreated" />
        <transition event="CXR.positive" target="somethingelse"/>
<state id="untreated" />

The custom ntd:test tag fires a CXR.negative event. 

Now the SCXMLListener reports this for the onentry's and onexit's

Getting a List of Dates from Apache Commons DBUtils


I am trying to get a list of dates from a table.

This kind of query works well with Strings and my own POJOs, but for some
reason does not work on java.sql.Date's.

Query :

sql = "select EVENT_DATE TIME from EVENT_TABLE";

EVENT_DATE in EVENT_TABLE is a valid date field.

Java code :

ResultSetHandler<List<java.sql.Date>> h = new
QueryRunner db = new QueryRunner(dataSource,true);
List<java.sql.Date> sqlDates = db.query(sql, h,new
java.sql.Date(from.getTime()),new java.sql.Date(to.getTime()));

Commons Validation with Spring MVC 3+

We looking into converting a struts 1 web app to Spring.  One of the major hurdles we ran into was the lack of
support for commons validator with the current versions of spring.  It looked like an adapter was created a
while back to support this but has since been deprecated.  Does anyone know of any options we might have to
support the  Commons Validator with Spring 3+?  We would really like to avoid having to manually convert our
extensive xml validation logic to annotated validation if possible.  Any information or suggestions
would be great.

[compress] Getting external attributes from a ZipArchiveEntry

ZipArchiveEntry.getExternalAttributes() is always returning 0 for me.  I
have pasted a hex dump of the zip file I'm testing with at the bottom of
email: 2 files of 0 bytes, one named x and one named y.  Both of their
external attributes are 33184 (a081 in the hex dump).  However, running the
following program gives me 0 for both of their external attributes:



public class Foo {
  public static void main(String args[]) throws IOException {
    File archiveFile = new File("");
    try (InputStream is = new FileInputStream(archiveFile)) {
      ZipArchiveInputStream in = new ZipArchiveInputStream(is);
      ZipArchiveEntry entry = in.getNextZipEntry();
      while (entry != null) {
        System.out.println("entry: " + entry);
        System.out.println("external: " + entry.getExternalAttributes());
        entry = in.getNextZipEntry();

Do I need to do something different to get the external attributes?  Is
