1 SOAP client examples

A SOAP request can be formulated by generating an XML message that will be transported using the HTTP protocol. The creation of the XML message (serialization) and the obtaining fo the response (deserialization) can be done through different languages.

Below are some examples in the most common languages.

 

1.1 XSQL-Script client

This section shows several examples of SOAP clients using the XSQL-SCRIPTS language.

 

1.1.1 SOAPSQLServer.executeQuery

 

Example 1

Execute an SQL query.

Copy
<xsql-script name='executeSQL1'>
  <body>
     <set name='m_response'>
        <soap.call
           url='http://www.mydeister.com/soap/servlet/rpcrouter'
           uri='urn:SOAPSQLServer'
           method='executeQuery'
           user='soap'
           password='soap999'
           >
             <parameters>
             	<parameter name='dbms'>demo_sports</parameter>
             	<parameter name='sqlcmd'>SELECT codigo, nomdia FROM cdiarios WHERE codigo='DC'</parameter>
             </parameters>  
        </soap.call>
     </set>
       <if><expr><soap.isFault><m_response/></soap.isFault></expr>
           <then>
                <println><soap.fault.getCode><m_response/></soap.fault.getCode></println>
                <println><soap.fault.getString><m_response/></soap.fault.getString></println>
           </then>
           <else>
               <println><m_response/></println>
               <println><map.get name='m_response'><string>codigo</string></map.get></println>
               <println><map.get name='m_response'><string>nomdia</string></map.get></println>
           </else>
       </if>       
  </body>
</xsql-script>
 

Example 2

Executes an SQL query that returns one or more columns of one or more records. It returns a map where each entry referenced by the name of the column contains an array for the values of that column in each of the different records obtained.

Copy
<xsql-script name='sample_executeQueryMultRow'>
    <body>
       <set name='m_response'>
          <soap.call
             url='http://www.mydeister.com/soap/servlet/rpcrouter'
             uri='urn:SOAPSQLServer'
             method='executeQuery'
             user='soap'
             password='soap123'
             >
         <parameters>
                <parameter name='dbms'>demo_sports</parameter>
                <parameter name='sqlcmd'>SELECT * FROM cdiarios</parameter>
                <parameter name='allowMultiRow'><boolean.true /></parameter>
             </parameters>
          </soap.call>
       </set>
       <if><expr><soap.isFault><m_response/></soap.isFault></expr>
           <then>
                <println><soap.fault.getCode><m_response/></soap.fault.getCode></println>
                <println><soap.fault.getString><m_response/></soap.fault.getString></println>
           </then>
           <else>
                <set name='l_nomdia'><map.get name='m_response'><string>nomdia</string></map.get></set>
                <iterator name='s_code' index='idx'>
                    <in>
                        <map.get name='m_response'><string>codigo</string></map.get>
                    </in>
                    <do>
                        <println></println>
                        <println>ROW <idx/></println>
                        <println>CODIGO: <s_code/></println>
                        <println>NOMDIA: <array.get name='l_nomdia'><idx/></array.get></println>
                    </do>
                </iterator>
           </else>
       </if>
    </body>
</xsql-script>
 

1.1.2 SOAPSQLServer.getQueryValue

1.2 Java Client (Apache SOAP 2.3)

In this section, we will show several examples of java clients developed using APACHE SOAP libraries.

 

1.2.1 Previous requirements

To compile or execute the examples detailed in this section, at least the libraries listed below are required and can be found at common/lib/webstudio:

  • common/lib/webstudio/soap.jar (Apache Soap 2.3)
  • common/lib/webstudio/activation.jar (JavaBeans Activation Framework.)
  • common/lib/webstudio/mail/jmail_1_4_mail.jar (Java Mail 1.4)
 

1.2.2 Compilation

An example of compiling a java client could be the following, where SOAPOBJClient1.java is the java code file:

Copy
javac -classpath soap.jar SOAPOBJClient1.java
 

1.2.3 Execution

An example of executing a java client could be the following, where SOAPOBJClient1 is the java class file, to which two arguments are passed:

Copy
java -classpath soap.jar;jmail_1_4_mail.jar;activation.jar;. SOAPOBJClient1 http://192.10.10.1/soap/servlet/rpcrouter demo_sports1
 

1.2.4 SOAPSQLServer.executeSQL

The following example shows a service call routine SOAPSQLServer.executeSQL(String database, String sqlcmd, int[] sqltype, Object[] sqldata, boolean gzip)

Copy

1.3 Java Client (Apache Axis 1.x)

In this section, we will show several examples of java clients developed using AXIS libraries.

 

1.3.1 Previous requirements

To compile or execute the examples described in this section, we need at least the following packages available from APACHE AXIS:

  • axis.jar
  • jaxrpc.jar
  • wsdl4j-1.5.1.jar
  • commons-logging-1.0.4.jar
  • commons-discovery-0.2.jar
 

1.3.2 Compilation

An example of compiling a java client could be the following, where AXISExecuteQueryClient.java is the java code file:

Copy
javac  -classpath axis.jar;jaxrpc.jar AXISExecuteQueryClient.java
 

1.3.3 Execution

An example of executing a java client could be the following, where AXISExecuteQueryClient is the java class file, to which is passed four arguments:

Copy
java -classpath axis.jar;jaxrpc.jar;wsdl4j-1.5.1.jar;commons-logging-1.0.4.jar;commons-discovery-0.2.jar;. AXISExecuteQueryClient
 http://webstudioserver/soap/servlet/rpcrouter USER PASSWORD demo_sports "SELECT COUNT(*) contador, MAX(docser) docser from gcomfach"
 

1.3.4 SOAPSQLServer.executeQuery

 

Example 1

This example shows how to invoke the SOAPSQLServer.executeQuery service to execute a simple SQL statement.

1.6 RAW Java Client

When in Java you do not have a serialization library such as Apache SOAP (on an Android device), you can make soap messages directly and negotiate with the server in direct http protocol. This mencanism requires more advanced knowledge of Java and interoperability with SOAP. The serialization and deserialization process can be especially complex.

 

1.6.1 Example 1

The following example shows a service call routine SOAPSQLServer.executeSQL (String database, String stmt)
