I am having problem while using code for adding digital signature to pdf file. Here is the link of the code http://developer.arx.com/quick-start/sapi-web-services/#tab=t-helloworld . There are some classes in the code which are needed to import in before running, but the package of these classes isn't available in java version 1.6, I am using IBM lotus notes which supports upto java version 1.6. Please help me out.
The java classes in the code sample were indeed generated with Java version 1.7. All you need is to generate new classes compatible with your own environment. Here you can find an explanation on how to do it using the wsimport JDK utility.
