dotNet4Java Importer

The dotNet4Java Importer is a graphical User Interface which is used for importing .Net Assemblies such as dll or exe files, WSDL or web service XML schema and for generating java class files from the .Net types of the imported assemblies.

The dotNet4Java Importer is part of the dotNet4Java.

Import .Net Assemblies Wizard

This wizard is used for importing .Net assemblies and for generating Java classes from the types of the imported assemblies.

STEP 1
- Click on the add button to add .Net Assembly files to the Assembly Names list. The assemblies can be removed by selecting the assemblies on the list and subsequently clicking on the remove button.
- The right part of the screen above displays the properties of the assemblies to be imported. The Java package name for the assembly will be the lower case name of the assembly to be imported. For instance, the name of the above assembly on the list is System.Data and the package name is system.data
- To load assemblies from the Global Assembly Cache (GAC), click on the GAC button and the GAC assembly form will be shown. Select the assemblies to import from the GAC assembly screen and click the Ok button to add the selected assemblies to the list.
Click the Next button and go to step 2.

STEP 2
- This screen allows you to specify which types and the members of the types of the assemblies you want to import. The members of a type includes the Constructors, Fields, Properties, Methods and Events. On the screen above, the SqlConnection type has been selected and atleast one member item has also been selected for each member of the type.
Click the Next button and go to step 3.

STEP 3

This screen allows you to determine how the imported assemblies should be loaded by the host package at runtime. There are four load assembly options; These are:
Load from GAC using Qualified Assembly Name: Selecting this option allows the host package to load the assembly from the Global Assembly Cache using the qualified assembly name. Example: System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089

Load from GAC using Partial Assembly Name: Selecting this option allows the host package to load the assembly from the Global Assembly Cache using the partial name of the assembly. Considering the above example, instead of specifying the full qualified name, you can specify only the name of the assembly. Example: System.Data

Load from File Location: Selecting this option allows the host package to load the assembly from the specified file location.
Click the Next button and go to step 4.

STEP 4

This screen allows you to specify the directory where the generated java files will be stored after import.

Click the Finish Button to start the process.

After the process is complete, each type selected to imported will have a correpsonding java class generated. Another resource java class will be generated for each of the .Net assembly imported. Below is the example of the Java classes generated for the SqlCeConnection type and it members in the System.Data.SqlServerCe assembly imported:

Import WSDL/Web Services Wizard

This wizard is used for importing Web Service Description language file/url (WSDL) or XML schema and for generating Java classes from the types of the imported wsdl assemblies.

STEP 1

Enter either a WSDL file name or the URL where the document is published (WSDL Document). Click the ellipsis button next to the edit box to browse for a file location. After entering a file name or URL, select the protocol type (By default SOAP protocol is selected) used to communicate with the WSDL document or XML Web services. The following are the types of protocol:
- Process only WSDL Binding extensions for SOAP Protocol: The process communicates with the service using the latest SOAP protocol.
- Process only WSDL Binding extensions for HTTP POST Protocol: The process communicates with the service using HTTP POST protocol.
- Process only WSDL Binding extensions for HTTP GET Protocol: The process communicates with the service using HTTP GET protocol.
- Process only WSDL Binding extensions for HTTP SOAP Protocol: The process communicates with the service using HTTP SOAP protocol.
If the WSDL document requires a credential for authentication, then specify:
- Domain: Indicates the domain to use if the WSDL document is on a secure server that requires authentication. (Optional).
- UserName: Indicates the username to use if the WSDL document is on a secure server that requires authentication.
- Password: Indicates the password to use with User Name when the WSDL document is on a secure server that requires authentication.
Click the Next button and go to step 2.
