fglwsdl

The fglwsdl tool produces web services stub files for client or server programs (from WSDL / XSD).

Syntax

fglwsdl [command] [options] [ argument ]

command indicates what operation must be done by fglwsdl. Commands are optional. If you do not specify a command, fglwsdl defaults to creating the client stub (option -c).
options are described in fglwsdl options.
argument is a parameter for command.

Commands

Table 1. fglwsdl commands
Command	Description
`-V`	Displays version information.
`-h`	Displays options for the tool.
`-l`	List services from a WSDL or variables from a XSD
`-c [options] wsdl-spec`	Generate client stub (default) to be used in a GWS client application. `wsdl-spec` is the name of a WSDL description file or the URL of a WSDL description for a published web service. Typically, `http://host/service?WSDL`. The `options` are listed in Table 2 and Table 4. To generate legacy files (.inc and .4gl) use the `-legacy` option.
`-s {module-name} [options] wsdl-spec`	Generate server stub to be used in a GWS server application. A `module-name` must be specified where service operations are defined. The `wsdl-spec` is the name of a WSDL description file or the URL of a WSDL description for a published web service. Typically, `http://host/service?WSDL`. The `options` are listed in Table 2 and Table 4. To generate legacy files (.inc and .4gl) use the `-legacy` option instead of the `module-name`.
`-x [options] xsd-spec`	Generate BDL data types from a XML schema (XSD). `xsd-spec` is the name of an XML schema file or the URL of an XSD schema resource on the web. The `options` are listed in Table 3 and Table 4.
`-regex regex value`	Validate the `value` against the `regex` regular expression described in XML schema specification.

Options

Table 2. WSDL Options
Options	Description
`-o file`	Specify a base name for the output files.
`-n service port`	Generate only for the given service name and port type.
`-b binding`	Generate only for the given binding.
`-prefix name`	Add `name` as the prefix of the generated web service functions, variables and types. (`name` can contain `%s` for servicename, `%p` for portname and `%f` for filename)
`-compatibility`	Generate a Genero 1.xx compatibility client stub.
`-fRPC`	Force RPC convention; use RPC Convention to generate the code, regardless of what the WSDL information contains.
`-fRPCNamespace`	Generate code to support the `namespace` attribute for RPC parameters.
`-disk`	Save WSDL and all dependencies from a URL on the disk. To generate code at the same time, you must use the option `-c`, `-s`, or both. Otherwise, no code is generated.
`-domHandler` `{module-name}` `[options]` `wsdl-spec`	Generates the use of DOM in the client stub and calls to callback handlers. A `module-name` must be specified where the callback functions called by the stub are defined. The `wsdl-spec` is the name of a WSDL description file or the URL of a WSDL description for a published web service. Typically, `http://host/service?WSDL`. See The generated callback handlers. The `options` are listed in Table 2 and Table 4. To generate legacy files (.inc and .4gl) use the `-legacy` option instead of the `module-name`.
`-alias`	Generates FGLPROFILE Logical names in place of URLs for the client stub.
`-soap11`	Generates only client and server stubs supporting SOAP 1.1 protocol.
`-soap12`	Generates only client and server stubs supporting SOAP 1.2 protocol.
`-ignoreFaults`	Do not generate extra code to handle SOAP faults.
`-wsa { yes \| no }`	Force support of WS-Addressing 1.0 if `yes`, disable support of WS-Addressing 1.0 if `no`, otherwise support WS-Addressing 1.0 according to the WSDL definition.
`-mtom { yes \| no }`	Override the WSDL MTOM policy with this option. If `yes`, generates the stub with MTOM support. If `no`, generates the stub without MTOM support. This option can be applied to the client side or server side.
`-xmlname`	Generate the name of variables with XMLName attributes when generating stubs. This option may be useful when you need to serialize subrecords.

Table 3. XSD Options
Options	Description
`-o file`	Name of the output file. If `file` has no extension, .inc is added.
`-n name [ ns ]`	Generate only for the given variable name and namespace (if there is one).
`-prefix name`	Add `name` as the prefix of the generated data types.
`-disk`	Save XSD and all dependencies from a URL on the disk. No code is generated.
`-hexb64AsString`	Generate all XSD base64 and hexBinary type as BDL STRING. If the WSDL has a Message Transmission Optimization Mechanism (MTOM) policy, the tool generates any xsd:base64Binary and xsd:hexBinary as a STRING data type with the XMLOptimizedContent attribute (instead of a BYTE data type). The STRING represents a filename on disk, that will be handled as a SOAP-attached file. Tip: This option is useful for avoiding loading a file into a BYTE each time you want to send a big file. If the WSDL does not have an MTOM policy, the tool generates any xsd:base64Binary and xsd:hexBinary as a STRING data type (instead of a BYTE data type). The programmer is responsible for setting a base64 or hexBinary value to the STRING in order to avoid a XML serialization error with the peer, as the latter expects a base64 or an hexBinary value.

Table 4. Common options
Options	Description
`-legacy`	Generate legacy code (Genero 3.20 or prior) with two stub files: a globals file .inc, and a .4gl. Works with the options `-c`, `-s`, or `-domHandler`. See Backward compatibility for globals.
`-comment`	Add XML comments to the generation.
`-fArray`	Force XML array generation instead of XML list when possible. If the WSDL contains an XML definition of a BDL list, generate a BDL array matching the same definition.
`-fInheritance`	Force generation of XML choice records for all inheritance types found in the schemas, otherwise only for abstract types and elements.
`-fInlineTypes`	Force generation of `TYPE` definitions for all global inlined types found in the schemas.
`-noFacets`	Don't generate facet constraints restricting the value-space of simple data type.
`-legacyTypes`	Don't generate BIGINT, TINYINT and BOOLEAN data types.
`-ignoreMixed`	Ignore the attribute `mixed="true"` that allows mixed content to appear between child elements of complexType elements in XML schemas. When generating code from a WSDL using mixed complex types (`<xs:complexType mixed="true">`), fglwsdl will produce an error message: `Mixed complexType is not supported` if the option is not used.
`-ext schema`	Add an external schema. See option '`-extDir`'.
`-extDir directory`	Add all external schema files ending with .xsd in the directory. External schemas for dependencies won't be included in the WSDL description or in the XSD schema if their location attributes are missing. Use this option to add a missing external schema for a WSDL or XSD dependency.
`-noValidation`	Disable XML schema validation warnings.
`-autoNsPrefix nb`	Automatic prefix generation for variables and types using a substring of the namespace by removing the `nb` first elements (-1 means only the last element). For example: If a variable belongs to the namespace `http://www.mycompany.com/Global/Service`, a value of -1 will give `Service` as a prefix, and a value of 1 will give `Global_Service` as a prefix.
`-nsPrefix ns value`	Add `value` as prefix of the generated variables and types belonging to namespace `ns` (supersede the `-prefix` and the `-autoNsPrefix` option, and can be called several times).

Table 5. Network options (when specifying a URL)
Options	Description
`-noHTTP`	Disable HTTP - search for the WSDL description or the XML schema and its dependencies on the client instead of the internet. Useful, for example, if a company has restricted access to the internet.
`-proxy location`	Connect via proxy where `location` is host[:port] or ip[:port].
`-pAuth login pass`	Proxy authentication login and password.
`-hAuth login pass`	HTTP authentication login and password.
`-cert cert`	File of the X509 PEM-encoded certificate for HTTPS purpose.
`-key key`	File of the PEM-encoded private key for HTTPS purpose.
`-wCert cert`	Certificate name in the Windows® keystore for HTTPS purposes (Windows only).
`-CA list`	A filename with the list of concatenated X509 PEM-encoded certificate authorities. (On Windows, if not set, the Certificate Authority list of the key store is used).
`-SSLOptions`	Set SSL options when connecting to a server not supporting secure renegotiation — an unpatched server. For example, to ensure you can connect to the server, configure these option flags (a pipe (`\|`) separator must be placed between flags): `-SSLOptions SSL_OP_NO_TLSv1_3\|SSL_OP_LEGACY_SERVER_CONNECT` For more details on OpenSSL SSL_OP flags, refer to the OpenSSL (external link) documentation. Warning: Using unsafe SSL connections Using `-SSLOptions` has security implications. It should not be used unless you are unable to upgrade the server with the latest security fixes.

Usage

The fglwsdl command line tool produces the WSDL description of a web service that will be accessed by a GWS client application, or to define a WSDL description for creating a corresponding GWS server application. The tool generates the BDL data types from XML schemas (also known as XSD).

To access a remote web service, you must get the WSDL information from the service provider. Sample services can be found through UDDI registries, for example (http://www.uddi.org).

These are examples of common commands used by SOAP Web service developers.

In the next examples, the -soap12 option is used to generate stubs supporting the SOAP 1.2 protocol. Alternatively, you can specify SOAP 1.1 with the -soap11 option. Omitting the SOAP option, fglwsdl generates two stub files, one for SOAP 1.1 and one for SOAP 1.2.

Generate client stub file

This example command requests the Web service information for the "MyService" service running on the localhost. The command generates a client stub file and outputs it to "Example2Client.4gl" file:

fglwsdl -c -soap12 -o Example1Client http://localhost:8090/MyService?WSDL

Generate server stub file

A fglwsdl command with the -s module-name option creates a server stub file for the service. In the module-name you must provide the name of the module where you implement the functions for the service operations.

For example, this command performs several operations at once:

fglwsdl -s serviceImp -soap12 -o example2Server http://localhost:8090/MyService?WSDL

It generates the server stub based on the WSDL for the service running on the localhost.
In the generated stub file (.4gl) it includes an IMPORT FGL module-name ("serviceImp" in the sample) statement to reference the operations the service publishes at runtime.
It adds "Service" to the base filename specified in the output. Therefore, the generated file in the example is "example2ServerService.4gl".
To use the service, you must compile the generated file and import it into your GWS server application ("serviceImp" in the example).

Backward compatibility for globals

If you need to generate stub files (.inc and .4gl) for compatibility with your legacy code (Genero 3.20 or prior), the fglwsdl tool has a -legacy option for this purpose.

This example command generates two files (.inc and .4gl) for the client stub with the base name "example2ClientLegacy":

fglwsdl -c -legacy -soap12 -o example2ClientLegacy http://localhost:8090/MyService?WSDL

The following example command generates legacy code for the server stub. It adds "Service" to the base filename specified in the output. Therefore, the generated files (.inc and .4gl) will be "example2ServerLegacyService". The stub file (.4gl) must be compiled and linked into your GWS server application.

fglwsdl -s -legacy -soap12 -o example2ServerLegacy http://localhost:8090/MyService?WSDL
