In the case proposed by Diony , signing multiple elements by id, simply change the newSignedInfo to:
// Create the SignedInfo
final List transforms0...
I must admit that I don't understand transformations, so take my example code with a grain of salt.
Also, signing a doc fragment by PATH does not work, simply because there's no way to identify the fragment with a URI without referring to it by id. Reference ode from org.jcp.xml.dsig.internal.dom.DOMURIDereferencer :
// Check if same-document URI and register...

It's normal practice to import types from an external xsd file in WSDL like this:
<wsdl:types> <xsd:schema xmlns:xsd="htt... When you use <dynamic-wsdl> and have Commons XMLSchema on the class path, Spring-WS inlines the xsd in the wsdl. But that doesn't happen when you use <static-wsdl> . You can define a SimpleXsdSchema bean to expose the xsd: <?xml version="1.0" encoding="UTF-8"?> <beans x... where the bean id "hello" should match the schemaLocation attribute in the WSDL (without the .xsd suffix). But note that the SimpleXsdSchema does not inline the xsd. It only makes the xsd available via an HTTP URL. Alternatively, you can simply put the xsd file under the content directory of the webapp (just link any CSS or JavaScript). Anyway, that's a lot of manual...

According to wikipedia , only two characters are invalid in a file name:
In Unix-like file systems the null character, as that is the end-of-string indicator and the path separator / are prohibited.

The command " svn info " prints information about the current directory:
$ svn info Path: . URL: http://svn.example.c... where: Revision: is the last syncup (update) revision of the current TARGET (artifact/file/directory, whatever you call). This number bumps up to that of the current project revision number after you do an update. Last Changed Rev: is the revision number of the latest change for the current TARGET . If TARGET is a directory, it is the revision number of the latest change within the directory, including all subdirectories. However , this number is not accurate after you do a check in without a following update . The revision number for the file or directory you checked in will have higher revision number than its parent/ancestor....

You can use the system call from the os module to execute an external program:
>>> import os
>>> os.system(the_command_line_st...
However, the path to the executable contains a space character, the system call treats the strings after the first space as arguments, causing an error.
Python doc recommends the use of the subprocess module:
The subprocess module provides more powerful facilities for spawning new processes and retrieving their results; using that module is preferable to using this function.
For example, using wget to get the google home page:
>>> from subprocess import Popen, PIPE
>>> (out...
or
>>> import subprocess
>>> subprocess.call(['cur...

This trick sets HTML base to the root context path of the current webapp:
The short version:
<!DOCTYPE html>
<%@ taglib uri="http://java.sun...
The long version:
<!DOCTYPE html>

In my JSP there's a link like this:
<a href="/path/${part1}/${part2}">the link</a>
where part1 and part2 may contain characters that need to be URL encoded (such as '#').
JSP JSTL does not provide such facility out of the box. But there's a hack using <c:url> , or you can use <spring:url> :
JSTL hack:
<c:url value="/path" var="theUrl">
<c:param...
Using Spring url tag:
<spring:url value="/path/{part1}/{part2}" var="enc...

Use the copy command to restore a deleted file:
$ svn copy http://svn.example.com/path/to/svn/repo...
@revision must be a revision number before the file was deleted.
You can use the info command to view the info before restoring:
$ svn info http://svn.example.com/path/to/svn/repo...

An alias defined in .profile does not work when you open a bash window from the desktop. Simply put, alias should be put in .bashrc ; PATH should be put in .profile . These are the facts: .profile is executed by the login shell, i.e., when you login. .bashrc is executed whenever a bash shell is opened - login or non-login. When you open a new bash window from the desktop, a non-login shell is created, it will execute .bashrc , not .profile . When you ssh to a remote system interactively, a login shell is created. When you ssh to a remote system and run a command directly, a non-login shell is created. PATH modifications should be put in .profile since it is usually...

Here are some ways to add shared libraries to the Linux loader search path:
Copy the library to one of the standard paths (for example, /usr/lib ), then run ldconfig
Add the path to /etc/ld.so.conf , then run ldconfig (for details, man ldconfig ).
Use the environment variable LD_LIBRARY_PATH .
