EQUELLA Java SOAP Tutorial

Table of Contents

Running the examples

To compile and execute the example code you will need to download a number of library jar files. See the readme.txt file in the samples/java/lib directory for more information.

Use of an Integration Development Environment (IDE) is recommended for editing of the files. Eclipse is a free IDE available at

You can create a new project file in Eclipse by selecting New -> Project… -> Java Project and click Next. Unselect the Use default location checkbox and browse to the samples/java folder of this integration pack. Now click Finish.

To run the example files, modify the in the samples/java/src/org/example/soap folder with the appropriate values (SOAP endpoint, username and password). The SOAP endpoint is of the format: http://INSTITUTION_URL/services/SoapService50

For example:

Guide to the example code

The classes in the com.tle.web.remoting.soap package were generated with Apache Axis with the following command line:

java -cp axis.jar;commons-logging-1.0.4.jar;commons-discovery-0.2.jar;jaxrpc.jar;wsdl4j-1.5.1.jar org.apache.axis.wsdl.WSDL2Java http://

In this way, you can build classes to invoke SOAP methods for any SOAP service exposed by EQUELLA. E.g. the copyright SOAP service at http://INSTITUTION_URL/services/calactivation.service?wsdl

The example code contains a helper class (EQUELLASOAP) which you are free to use and modify. This class has been created to simplify the processing of the XML results and XML parameters returned from and supplied to the SOAP methods, it also ensures the user’s session is maintained between SOAP calls by setting setMaintainSession(true) on the SOAP service locator object. The EQUELLASOAP class is not required to use the EQUELLA SOAP services, it is simply for convenience.

This example shows how you can retrieve a list of items from EQUELLA based on a few search parameters. The searching code is contained within the cmdSearch_Click method. Here is a summary of that code:


This example shows how you can contribute an item to a collection and give it a name, description and a file attachment. The contribution code is contained within the cmdSubmit_Click method. Here is a summary of that code:

Writing your own code

In general the process for invoking a SOAP method is as follows:

  1. Create a SoapService50 object. When creating a SoapService50 object, you should supply the URL to connect to although this is not strictly necessary. You MUST set a cookie handler on the SoapService50 object before invoking the login method. This is because the user session is retrieved from the cookie by the EQUELLA server; if you do not set a cookie handler your session will be lost immediately after calling login. When using Apache Axis, you can easily do this by setting setMaintainSession(true) on the generated locator class.
  2. Call the login method:
    client.login(username, password);

    The user that you login as must have sufficient privileges to perform your required task. You cannot do anything over SOAP that you cannot do within the EQUELLA Digital Repository.

  3. Invoke a method:
    collectionsXml = client.getContributableCollections();

NOTE: All SOAP methods will return either a simple string, number or an XML string. We recommend using the XmlDocument class to parse the results of any SOAP call.

  1. Call the logout method.

This is not strictly necessary, the user session will eventually time out on the server, but it is good practice to call logout to free server side resources.
