Your Application


Jchem web services server

Introduction to Web Services

  • Interoperability

  • Allows applications to communicate independent of:

    • Platform

    • Programming language

Your Applications


Jchem web services server

Army of One or Architected Team

  • A single service can power a simple application.

  • Services are the building blocks

    • Work with other Web services or desktop applications

    • Part of a Service-Oriented Architecture


Standards and languages

Standards and Languages

WS-I, SOAP, and WSDL standards

Reusable and accessible to other services

Automated client-side code generation

  • Supports

  • Web Languages: AJAX/JavaScript, Perl, Python, Ruby, PHP, …

  • App languages: Java, C#, …

  • Growing list of JChem Modules (Searching, Standardization, Chemical Terms, Molecule Conversion…)

loc = ChemicalTermsWS_client.ChemicalTermsWSLocator()

evaluator = loc.getChemicalTermsWSHttpSoap11Endpoint()

req = ChemicalTermsWS_client.evaluateReturnNumRequest()

req.Target = ‘CC=CC’

req.Expression = ‘logp’

resp = evaluator.evaluateReturnNum(req)

var xhr = new XMLHttpRequest();

xhr.open(method, url, async);

xhr.setRequestHeader('Content-Type', 'text/xml; charset=utf-8');

xhr.send(createEvaluateReturnNumRequest(“CC=CC”, “logp”);

  • <soap:Body>

    • <evaluateReturnNum xmlns="http://webservice.jchem.chemaxon">

      • <target>CC=CC</target>

      • <expression>logp</expression>

    • </evaluateReturnNum>

  • </soap:Body>
