XML Digital Signature API Examples

The following sections describe two examples that show how to use the XML
Digital Signature API:

· Validate example

· Signing example

To run the sample applications using the supplied Ant

build.xml

files, issue the

following commands after you installed Java WSDP:

For Solaris/Linux:

1. % export JWSDP_HOME=<your Java WSDP installation directory>
2. % export ANT_HOME=$JWSDP_HOME/apache-ant

% export PATH=$ANT_HOME/bin:$PATH

% cd $JWSDP_HOME/xmldsig/samples/<sample-name>

For Windows 2000/XP:

> set JWSDP_HOME=<your Java WSDP installation directory>

2. > set ANT_HOME=%JWSDP_HOME%\apache-ant
3. > set PATH=%ANT_HOME%\bin;%PATH%
4. > cd %JWSDP_HOME%\xmldsig\samples\<sample-name>

validate Example

You can find the code shown in this section in the

Validate.java

file in the

<JWSDP_HOME>/xmldsig/samples/validate

directory. The file on which it

operates,

envelopedSignature.xml

, is in the same directory.

To run the example, execute the following command from the

<JWSDP_HOME>/

xmldsig/samples/validate

directory:

$ ant
