Method ListsResources.getUserListMemberships not recognized in Twitter4J 4.0.4

when calling
twitter.list().getUserListMemberships(userId, 1000,1,false);
I get this error:
java.lang.NoSuchMethodError: twitter4j.api.ListsResources.getUserListMemberships(JIJ)Ltwitter4j/PagableResponseList;
I read the javadoc for this method (see here), and I don't see what I am doing wrong? And I did verify that my dependencies are OK. Any clue?

I just use Twitter4j 4.0.2 and that method doesn't exist
But on Twitter4j 4.0.4 does exist
So, Are you sure that you are using 4.0.4?
Keep in mind too that you are using cursor 1 on the first call but you have to use -1. I just run this code and works
User user = twitter.showUser("lt_deportes");
long cursor = -1;
PagableResponseList<UserList> lists;
do {
lists = twitter.list().getUserListMemberships(user.getId(),1000,cursor,false);
for (UserList list : lists) {
System.out.println("id:" + list.getId() + ", name:" + list.getName() + ", description:"
+ list.getDescription() + ", slug:" + list.getSlug() + "");
}
} while ((cursor = lists.getNextCursor()) != 0);

No query defined for that name [getAuditTaskById]

When I tried to start a task using taskService.start(task.getId(), "krisv");, I get No query defined for that name [getAuditTaskById]. The bpmn file is very similar to the Evaluation.bpmn file. My current version of jbpmn is 6.2.
The code snippet is the following:
List<TaskSummary> tasks = taskService.getTasksAssignedAsPotentialOwner("krisv", "en-UK");
if (tasks.size() > 0) {
TaskSummary task = tasks.get(0);
System.out.println("Task id: " + task.getId());
System.out.println("'krisv' completing task " + task.getName() + ": " + task.getDescription());
System.out.println("Task status: " + task.getStatus().name());
System.out.println("Potential owners: " + task.getActualOwner().getId());
taskService.start(task.getId(), "krisv");
Map<String, Object> results = new HashMap<String, Object>();
results.put("performance", "exceeding");
taskService.complete(task.getId(), "krisv", results);
System.out.println("Completed task");
} else {
System.out.println("No tasks!");
}
The code above is almost a replicate of the ProcessTest.java file in the sample folder. The ProcessTest.java allows the completion of the tasks, but the exact same code doesn't in my custom java file.
Also, the current task's status is "reserved" if that is of any help. Thanks!

The query is defined in the jbpm-human-task-audit-audit jar, you need that on your classpath:
https://github.com/droolsjbpm/jbpm/blob/6.2.0.Final/jbpm-human-task/jbpm-human-task-audit/src/main/resources/META-INF/TaskAuditorm.xml#L40
And you need to make sure this file is referenced in your persistence.xml, like for example here:
https://github.com/droolsjbpm/jbpm/blob/6.2.0.Final/jbpm-test/src/main/resources/META-INF/persistence.xml#L15

java.lang.NullPointerException trying to get specific values from hashmap

I've spent several frustrating days on this now and would appreciate some help. I have a Java agent in Lotus Domino 8.5.3 which is activated by a cgi:POST from my Lotusscript validation agent which is checking that customer has filled in the Billing and delivery address form. This is the code that parses the incoming data into a HashMap where field names are mapped to their respective values.
HashMap hmParam = new HashMap(); //Our Hashmap for request_content data
//Grab transaction parameters from form that called agent (CGI: request_content)
if (contentDecoded != null) {
String[] arrParam = contentDecoded.split("&");
for(int i=0; i < arrParam.length; i++) {
int n = arrParam[i].indexOf("=");
String paramName = arrParam[i].substring(0, n);
String paramValue = arrParam[i].substring(n + 1, arrParam[i].length());
hmParam.put(paramName, paramValue); //Old HashMap
if (paramName.equalsIgnoreCase("transaction_id")) {
transactionID = paramValue;
description = "Order " + transactionID + " from Fareham Wine Cellar";
//System.out.println("OrderID = " + transactionID);
}
if (paramName.equalsIgnoreCase("amount")) {
orderTotal = paramValue;
}
if (paramName.equalsIgnoreCase("deliveryCharge")) {
shipping = paramValue;
}
}
}
The block of code above dates back over a year to my original integration of shopping cart to Barclays EPDQ payment gateway. In that agent I recover the specific values and build a form that is then submitted to EPDQ CPI later on in the agent like this;
out.print("<input type=\"hidden\" name=\"shipping\" value=\"");
out.println(hmParam.get("shipping") + "\">");
I want to do exactly the same thing here, except when I try the agent crashes with a null pointer exception. I can successfully iterate through the hashMap with the snippet below, so I know the data is present, but I can't understand why I can't use myHashMap.Get(key) to get each field value in the order I want them for the html form. The original agent in another application is still in use so what is going on? The data too is essentially unchanged String fieldnames mapped to String values.
Iterator it = cgiData.entrySet().iterator();
while (it.hasNext()) {
Map.Entry pairs = (Map.Entry)it.next();
out.println("<br />" + pairs.getKey() + " = " + pairs.getValue());
//System.out.println(pairs.getKey() + " = " + pairs.getValue());
}

I did two things that may have had an impact, in the process of trying to debug what was going on I needed these further imports;
import java.util.Iterator;
import java.util.Map;
Although I'm not iterating over the hashMap, I've left them in in case which gives me the option of dumping the hashMap out to my system audit trail when application is in production. In variations of the snippet below after it started working I was able to get to any of the data I needed, even if the value was Null, and toString() also seemed to be optional again, as it made no difference to the output.
String cgiValue = "";
cgiValue = hmParam.get("ship_to_lastname").toString();
out.println("<br />Lastname: " + cgiValue);
out.println("<br />Company name: " + hmParam.get("bill_to_company"));
out.println("<br />First name: " + hmParam.get("ship_to_firstname"));
The second thing I did, while trying to get code to work was I enabled the option "Compile Java code with debugging information" for the agent, this may have done something to the way the project was built within the Domino Developer client.
I think I have to put this down to some sort of internal error created when Domino Designer compiled the code. I had a major crash last night while working on this which necessitated a cold boot of my laptop. You also may find that when using Domino Designer 8.5.x that strange things can happen if you don't completely close down all the tasks from time to time with KillNotes

Jenkins/Hudson CLI API to modify the node labels using Groovy

Does anyone know how to modify the Jenkins/Hudson node labels in a non-manually way? I mean, thorough an API like the CLI API that this tool offers (without restarting Jenkins/Hudson of course).
My guess is that the best option is using a Groovy script to enter into the Jenkins/Hudson guts. Executing something like:
java -jar -s HUDSON_URL:8080 groovy /path/to/groovy.groovy
Being the content of that script something like:
for (aSlave in hudson.model.Hudson.instance.slaves) {
labels = aSlave.getAssignedLabels()
println labels
**aSlave.setLabel("blabla")** // this method doesn't exist, is there any other way???
}
Thanks in advance!

Note: the other answers are a bit old, so it could be that the API has appeared since then.
Node labels are accessed in the API as a single string, just like in the Configure screen.
To read and write labels: Node.getLabelString() and Node.setLabelString(String).
Note that you can get the effective labels as well via: Node.getAssignedLabels(), which returns a Collection of LabelAtom that includes dynamically computed labels such as the 'self-label' (representing the node name itself).
Last, these methods on the Node class are directly accessible from the slave objects also, e.g. as a System Groovy Script:
hudson = hudson.model.Hudson.instance
hudson.slaves.findAll { it.nodeName.equals("slave4") }.each { slave ->
print "Slave $slave.nodeName : Labels: $slave.labelString"
slave.labelString = slave.labelString + " " + "offline"
println " --> New labels: $slave.labelString"
}
hudson.save()

I've found a way to do this using the Groovy Postbuild Plugin.
I have a Jenkins job that takes a few parameters (NodeToUpdate, LabelName, DesiredState) and executes this content in the Groovy Postbuild Plugin:
nodeName = manager.envVars['NodeToUpdate']
labelName = manager.envVars['LabelName']
set = manager.envVars['DesiredState']
for (node in jenkins.model.Jenkins.instance.nodes) {
if (node.getNodeName().equals(nodeName)) {
manager.listener.logger.println("Found node to update: " + nodeName)
oldLabelString = node.getLabelString()
if (set.equals('true')) {
if (!oldLabelString.contains(labelName)) {
manager.listener.logger.println("Adding label '" + labelName + "' from node " + nodeName);
newLabelString = oldLabelString + " " + labelName
node.setLabelString(newLabelString)
node.save()
} else {
manager.listener.logger.println("Label '" + labelName + "' already exists on node " + nodeName)
}
}
else {
if (oldLabelString.contains(labelName)) {
manager.listener.logger.println("Removing label '" + labelName + "' from node " + nodeName)
newLabelString = oldLabelString.replaceAll(labelName, "")
node.setLabelString(newLabelString)
node.save()
} else {
manager.listener.logger.println("Label '" + labelName + "' doesn't exist on node " + nodeName)
}
}
}
}

I've not seen a way yet to change the slave label either.
I've taken to editing the main config.xml file and issuing a reload from the CLI.
This has it's own problems though - any jobs currently running are lost until the next jenkins restart - see https://issues.jenkins-ci.org/browse/JENKINS-3265

Obtain a share UpdateKey from LinkedIn using LinkedIn J and getNetworkUpdates() with Coldfusion

Using the "Network Updates API" example at the following link I am able to post network updates with no problem using client.postNetworkUpdate(updateText).
http://code.google.com/p/linkedin-j/wiki/GettingStarted
So posting works great.. However posting an update does not return an "UpdateKey" which is used to retrieve stats for post itself such as comments, likes, etc. Without the UpdateKey I cannot retrieve stats. So what I would like to do is post, then retrieve the last post using the getNetworkUpdates() function, and in that retrieval will be the UpdateKey that I need to use later to retrieve stats. Here's a sample script in Java on how to get network updates, but I need to do this in Coldfusion instead of Java.
Network network = client.getNetworkUpdates(EnumSet.of(NetworkUpdateType.STATUS_UPDATE));
System.out.println("Total updates fetched:" + network.getUpdates().getTotal());
for (Update update : network.getUpdates().getUpdateList()) {
System.out.println("-------------------------------");
System.out.println(update.getUpdateKey() + ":" + update.getUpdateContent().getPerson().getFirstName() + " " + update.getUpdateContent().getPerson().getLastName() + "->" + update.getUpdateContent().getPerson().getCurrentStatus());
if (update.getUpdateComments() != null) {
System.out.println("Total comments fetched:" + update.getUpdateComments().getTotal());
for (UpdateComment comment : update.getUpdateComments().getUpdateCommentList()) {
System.out.println(comment.getPerson().getFirstName() + " " + comment.getPerson().getLastName() + "->" + comment.getComment());
}
}
}
Anyone have any thoughts on how to accomplish this using Coldfusion?
Thanks

I have not used that api, but I am guessing you could use the first two lines to grab the number of updates. Then use the overloaded client.getNetworkUpdates(start, end) method to retrieve the last update and obtain its key.
Totally untested, but something along these lines:
<cfscript>
...
// not sure about accessing the STATUS_UPDATE enum. One of these should work:
// method 1
STATUS_UPDATE = createObject("java", "com.google.code.linkedinapi.client.enumeration.NetworkUpdateType$STATUS_UPDATE");
// method 2
NetworkUpdateType = createObject("java", "com.google.code.linkedinapi.client.enumeration.NetworkUpdateType");
STATUS_UPDATE = NetworkUpdateType.valueOf("STATUS_UPDATE");
enumSet = createObject("java", "java.util.EnumSet");
network = yourClientObject.getNetworkUpdates(enumSet.of(STATUS_UPDATE));
numOfUpdates = network.getUpdates().getTotal();
// Add error handling in case numOfUpdates = 0
result = yourClientObject.getNetworkUpdates(numOfUpdates, numOfUpdates);
lastUpdate = result.getUpdates().getUpdateList().get(0);
key = lastUpdate.getUpdateKey();
</cfscript>

You can also use socialauth library to retrieve updates and post status on linkedin.
