Is there a java api to access bugzilla? [closed]
Question
Is there a (standalone!) java api which wraps the XML-RPC interface to bugzilla? I don't want to program my own api for it, and I can't actually find a library which does this (and only this).
Update:
I'm looking for something like this http://oss.dbc.dk/bugzproxy/ only written in Java
Solution
I know this is a bit old thread but as it is quite possible that people with the same question could land up here I thought of sharing a blog post I wrote about four Java client libraries that I found for accessing Bugzilla: J2Bugzilla, B4J (Bugzilla for Java), Bugzilla Library, LightingBugAPI.

OTHER TIPS
There's Apache WS XML-RPC (now that's a mouthful!) which is a full XML-RPC implementation that you could use. I don't know BugZilla that well but assuming it supports XML-RPC, there shouldn't be any issues using the monstrous mouthful I just linked.
The library/API is called JAX-WS (or JAXB), and lets you call WS of any nature. Get the schema, generate the beans and proxies, call them.
Here's a simple example for using bugzilla api with Java.. http://codehelpline.blogspot.com/2010/08/how-to-access-bugzilla-webservice-api.html
Here is a nice comparison of 4 Bugzilla API libraries by Nandana Mihindukulasooriya, from which I excerpt:
There is also Mylyn which is supposed to run stand-alone outside Eclipse. However, I did not manage yet to have it stand-alone. You can give a try to my own Bugzilla Java API which tries to cover the most urgent needs: http://techblog.ralph-schuster.eu/b4j-bugzilla-for-java/
Mylyn could be a good choice for you.
If you need simpler setup or better control of how things happen, you can write your own XML-RPC calls to Bugzilla web-service interface. I have summarized the process on my blog: Chat to Bugzilla from Java using Apache XML-RPC.
To sum it up:
- get the Apache XML-RPC libs
- get the Apache HTTP Client from commons (older version)
Then use following class as a base class (it handles cookies etc.) and override it:
/**
* @author joshis_tweets
*/
public class BugzillaAbstractRPCCall {
private static XmlRpcClient client = null;
// Very simple cookie storage
private final static LinkedHashMap<String, String> cookies = new LinkedHashMap<String, String>();
private HashMap<String, Object> parameters = new HashMap<String, Object>();
private String command;
// path to Bugzilla XML-RPC interface
private static final String BZ_PATH = "https://localhost/bugzilla/xmlrpc.cgi";
/**
* Creates a new instance of the Bugzilla XML-RPC command executor for a specific command
* @param command A remote method associated with this instance of RPC call executor
*/
public BugzillaAbstractRPCCall(String command) {
synchronized (this) {
this.command = command;
if (client == null) { // assure the initialization is done only once
client = new XmlRpcClient();
XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();
try {
config.setServerURL(new URL(BZ_PATH));
} catch (MalformedURLException ex) {
Logger.getLogger(BugzillaAbstractRPCCall.class.getName()).log(Level.SEVERE, null, ex);
}
XmlRpcTransportFactory factory = new XmlRpcTransportFactory() {
public XmlRpcTransport getTransport() {
return new XmlRpcSunHttpTransport(client) {
private URLConnection conn;
@Override
protected URLConnection newURLConnection(URL pURL) throws IOException {
conn = super.newURLConnection(pURL);
return conn;
}
@Override
protected void initHttpHeaders(XmlRpcRequest pRequest) throws XmlRpcClientException {
super.initHttpHeaders(pRequest);
setCookies(conn);
}
@Override
protected void close() throws XmlRpcClientException {
getCookies(conn);
}
private void setCookies(URLConnection pConn) {
String cookieString = "";
for (String cookieName : cookies.keySet()) {
cookieString += "; " + cookieName + "=" + cookies.get(cookieName);
}
if (cookieString.length() > 2) {
setRequestHeader("Cookie", cookieString.substring(2));
}
}
private void getCookies(URLConnection pConn) {
String headerName = null;
for (int i = 1; (headerName = pConn.getHeaderFieldKey(i)) != null; i++) {
if (headerName.equals("Set-Cookie")) {
String cookie = pConn.getHeaderField(i);
cookie = cookie.substring(0, cookie.indexOf(";"));
String cookieName = cookie.substring(0, cookie.indexOf("="));
String cookieValue = cookie.substring(cookie.indexOf("=") + 1, cookie.length());
cookies.put(cookieName, cookieValue);
}
}
}
};
}
};
client.setTransportFactory(factory);
client.setConfig(config);
}
}
}
/**
* Get the parameters of this call, that were set using setParameter method
* @return Array with a parameter hashmap
*/
protected Object[] getParameters() {
return new Object[] {parameters};
}
/**
* Set parameter to a given value
* @param name Name of the parameter to be set
* @param value A value of the parameter to be set
* @return Previous value of the parameter, if it was set already.
*/
public Object setParameter(String name, Object value) {
return this.parameters.put(name, value);
}
/**
* Executes the XML-RPC call to Bugzilla instance and returns a map with result
* @return A map with response
* @throws XmlRpcException
*/
public Map execute() throws XmlRpcException {
return (Map) client.execute(command, this.getParameters());
}
}
Override the class by providing custom constructor and by adding methods:
public class BugzillaLoginCall extends BugzillaAbstractRPCCall {
/**
* Create a Bugzilla login call instance and set parameters
*/
public BugzillaLoginCall(String username, String password) {
super("User.login");
setParameter("login", username);
setParameter("password", password);
}
/**
* Perform the login action and set the login cookies
* @returns True if login is successful, false otherwise. The method sets Bugzilla login cookies.
*/
public static boolean login(String username, String password) {
Map result = null;
try {
// the result should contain one item with ID of logged in user
result = new BugzillaLoginCall(username, password).execute();
} catch (XmlRpcException ex) {
Logger.getLogger(BugzillaLoginCall.class.getName()).log(Level.SEVERE, null, ex);
}
// generally, this is the place to initialize model class from the result map
return !(result == null || result.isEmpty());
}
}
