crossAPI SI and Java
To integrate crossAPI SI into a Java application, it is necessary to use SOAP requests to interact with the API service. For this purpose, the Java SDK provides the SOAP with Attachments API for Java (SAAJ) to work with SOAP requests. Information on SAAJ including code examples is available at Java 5 Tutorial.
To process responses from crossAPI SI, the Java API for XML Processing (JAXP) can be used. This allows you to work with DOM documents. Information on JAXP is available at Java SE Tutorial.
