I'm trying to set up a webservice using axis2.
I've created a Dynamic Web Projet under Eclipse, using Apache Tomcat 7 and the dynamic web version 2.5. I've added the Axis 2 Facets to the configuration.
I have the following class :
package com.jo.ws;
public class Test {
public int add(int a, int b) {
return a + b;
}
}
I then created a WebService for the projet, using the Bottom up Java bean Web Service, and adding my Test class to the service implementation.
I chose the "Start Service" in the slider, and changed Apache Axis in the configuration to Axis 2. I then generated a default services.xml file using the default option.
I can access my projet on the web at the following adress :
http://localhost:8888/Axis2WS/
This displays the Axis 2 page, and I can see my service is active
http://localhost:8888/Axis2WS/services/listServices
The wsdl is correctly generated and displayed
I can post it if needed.
But now if I do this :
http://localhost:8888/Axis2WS/services/Test?method=add&a=2&b=1
I get this :
<soapenv:Reason xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope">
<soapenv:Text xml:lang="en-US">wrong number of arguments</soapenv:Text>
</soapenv:Reason>
I also got the error in my Eclipse console log, with the following stack trace :
[ERROR] wrong number of arguments
java.lang.IllegalArgumentException: wrong number of arguments

Any idea what I'm doing wrong ?
Thanks for your help !
The error came from the url I was typing in the browser..
The right url to invoke the method is :
http://localhost:8888/Axis2WS/services/Test/add?a=3&b=2
You need to replace the "?" with a "/" before the name of the method, and then write your parameters after you've added a "?" after the name of your method

My application get multiple request per second we have bot's crawling our site. I use Lucene for Indexing and searching. For the 1st request when the site is restart application opens the Lucene indexed file and store it. So from second request it will look into the stored object.
But the issue is till the file is completely open and store there are multiple request which will try to open the file again.
This causes the site to go out of memory after 5-10 minutes.
This are the following errors.

THIS LINE IS THE ERROR LINE

Is there a way to lock the file till it is store. Any solution to improve the way it should be implemented
You should have a look at the LockFactory of the NIOFSDirectory (inherited from parent Directory).
See LockFactory Javadoc for little more informations
Additional to this, your requirements look like a NRT (near-real-time) use case for me. If you like to index and search within a short time period and indexing will be done continuous a NRT implementation would make sense. I'm not sure if this is already a feature of lucene v4.2.
See Simple NRT tutorial for additional information.
I've created a Java web service with Eclipse that was working excellently yesterday but now all of a sudden Scanner can't locate the file even though it's in the same directory!
I've tried finding the absolute path of it and providing the exact path but still it insists it cannot find it. However, if I just run it as a Java application it finds it! Am I doing something wrong in terms of trying to read a file with a web service?
The code I would have goes like this:
try {
File file = new File("./data.txt");
Scanner sc = new Scanner(file);
String[] arr = new String[3];
while(sc.hasNextLine()) {
String s = sc.nextLine();
arr = s.split(",");
}
}catch (FileNotFoundException e) {
e.printStackTrace();
}
The error I keep getting when running as a web service is
file foundjava.io.FileNotFoundException: ./data.txt (The system cannot fin
d the file specified)

Does anyone know what the problem might be?
You are searching for the file in the wrong path.
Or the file isnt created when the program starts.
Please verify this two solutions, times ago a had the same issue.
(Posted on behalf of the OP).
Solved it. Just used ClassLoader and getResource() to actually find the file for Scanner to use and it worked!
if you run it as a Java application, "./data.txt" is in the same directory with this java class; if you run it as a web service,the directory is the work directory of server like jboss/jetty/tomcat ...
I wrote a very simple custom filter to filter results returned by Accumulo. This is the filter that I wrote
public class MyFilter extends Filter {
#Override
public boolean accept(Key key, Value val) {
Long page = 1L;
Integer limit = 25;
if(key.getColumnQualifier().getBytes().equals("Class".getBytes()) && val.get().equals("1".getBytes())) {
if(page == 1) {
return true;
}
limit--;
if(limit == 1L) {
page++;
limit = 25;
}
}
return false;
}
}
I added this filter to Accumulo's scanner like this
Set<Range> ranges = new HashSet<>();
IteratorSetting iter = new IteratorSetting(15, "MyFilter", MyFilter.class);
myScanner.addScanIterator(iter);
Iterator<Entry<Key, Value>> kys = myScanner.iterator();
while(kys.hasNext()) { // This is line 335 in com.latize.ulysses3.service.AccumuloPivotTable.getRows
Entry<Key, Value> e = kys.next();
ranges.add(Range.exact(e.getKey().getRow()));
}
But whenever I try to run this piece of code, I get this stacktrace
java.lang.RuntimeException: org.apache.accumulo.core.client.impl.AccumuloServerException: Error on server accumulo.tablet.2:9997

accumulo.tablet.2:9997 is the domain name of the machine that runs one of my tablet servers. The configuration is fine because other functions work properly. The port is up too. Can someone tell me why am I getting that error? Any help would be appreciated.
To use filter properly you have to add them to the accumulo classpath, typically by deploying the .jar file where the iterator is defined on each node of your system in $ACCUMULO_HOME/lib or $ACCUMULO_HOME/lib/ext. For a deeper understanding of iterators I recommend the very good documentation of accumulo.
For an easy deployment I'd like to suggest the use of Jenkins, Puppet or Chef. If this is to much of an effort for your project a simple shell script will do as well. You may find the cluster shell cssh very helpfull for administration issues as well! Be aware that you do NOT need any restart of accumulo after the deployment in the ext folder, however it is necessary for the lib folder.
I got the issue. I was getting a ClassNotFound exception when I checked the tserver's logs. It would seem I need to add the class to Accumulo's classpath. But if I want to get these filtered results as part of an application rather than run it from the terminal, how would I go about doing it? It is possible that I would not be able to add the filter to Accumulo's classpath.
This week I started using Vaadin and has made a big impression on me ever since. However, I came accross a problem which I am not able to resolve. Basically I made a web application where I display Contacts (stored in my database) and display them in a Table.
Since I am using Hibernate, I start off with the following lines of code:
JPAContainer<Contact>contactContainer = new JPAContainer<Contact>(Contact.class);
CachingMutableLocalEntityProvider<Contact> entityProvider = new CachingMutableLocalEntityProvider<Contact>(Contact.class, em);
contactContainer.setEntityProvider(entityProvider);
contactsList = new ContactsList(contactContainer);
As you can see, I pass my container to a class called ContactsList where the table etc. is built:
table = new Table();
table.setWidth(100, Unit.PERCENTAGE);
table.addStyleName(ValoTheme.TABLE_BORDERLESS);
table.addStyleName(ValoTheme.TABLE_COMPACT);
table.setSelectable(true);
table.setColumnCollapsingAllowed(true);
if(container != null)
{
table.setContainerDataSource(this.container);
table.setSortAscending(true);
table.setVisibleColumns("firstName", "lastName", "telephoneNr", "gsmNr", "creationDate");
table.setColumnHeaders(SpringUtil.getMessage("label.contacts_firstname", null),
SpringUtil.getMessage("label.contacts_lastname", null),
SpringUtil.getMessage("label.contacts_telephone_nr", null),
SpringUtil.getMessage("label.contacts_gsm_nr", null),
SpringUtil.getMessage("label.contacts_creationdate", null));
}
table.setMultiSelect(true);
table.setImmediate(true);
When I comment out all this code, my application runs perfectly without crashing (ofcourse not showing the contacts table) but when I try and compile this code, while debugging everything works well even after the table has been built but then a NPE is thrown in the class ServerRpcHandler on the lines:
if (invocation instanceof ServerRpcMethodInvocation) {
try {
ServerRpcManager.applyInvocation(connector,
(ServerRpcMethodInvocation) invocation);
} catch (RpcInvocationException e) {
manager.handleConnectorRelatedException(connector, e);
}
} else {

UPDATE
What might be useful to know is that I use this ContactList on a different page as well where I have the EXACT same lines of code but where it is able to show the table. Does this have something to do of having two EntityManagers and/or EntityProviders accessing the same data??
UPDATE2
#PersistenceContext
protected EntityManager em;
As per Update2 I saw you retrive at runtime your EntityManager with the annotation "#PersistenceContext".
This works out if you are using it in "CDI bean, EJB, Servlet, Servlet Listener, Servlet Filter, or JSF ManagedBean"
( http://tomee.apache.org/examples-trunk/injection-of-entitymanager/README.html )
My guess is that on the "other page" you are in a right context where the annotation works, while in "this" page you are not.
Check this and if it's the case I'd suggest to manually instantiate the EntityManager with for example
JPAContainerFactory.make(Contact.class, "PERSISTENCE_UNIT_NAME");
if you have/use a persistence.xml file in your project. Otherwise a way would be to custom create an EntityManagerFactory like
Persistence.createEntityManagerFactory( "persistence_unit_name", properties ).createEntityManager()
where properties is a Map of persistence properties like
Map<String, String> properties = new HashMap<String, String>();
properties.put(JDBC_DRIVER, this.jdbcDriver);
properties.put(JDBC_URL, this.url);
properties.put(JDBC_USER, this.username);
properties.put(JDBC_PASSWORD, this.password);
// Configure logging. FINE ensures all SQL is shown
properties.put(LOGGING_LEVEL, "FINE");
return properties;
The perk of EntityManager like this is that you can have it ready whenever you are in your app.
Cheers.
I am trying to load some Freemarker templating from the DB using stringLoader and executing them through template.process, but here is the problem, freemarker stuff like <#if... is executing but when I try to execute assign JspTaglibs it breaks.
Here is a simple example:
From the DB I get <#assign bean=JspTaglibs["/WEB-INF/struts-bean.tld]>, which i put in a in StringTemplateLoader. I create configuration, template.. so far everything is working. When I do template.process(data, out), the page reports:
Starting output:FreeMarker template error: The following has evaluated to null or missing: ==> JspTaglibs [in template "temp" at line 1, column 15] Tip: If the failing expression is known to be legally null/missing, either specify a default value with myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing. (These only cover the last step of the expression; to cover the whole expression, use parenthessis: (myOptionVar.foo)!myDefault, (myOptionVar.foo)?? The failing instruction (FTL stack trace): ---------- ==> #assign bean = JspTaglibs["/WEB-INF/s...

Scenario that I have is that I have some code stored in the database and I would like to execute it by freemarker during template.process().
Is that even possible, and if it is, what am I doing wrong?
The problem is that JspTaglibs is not a core FreeMarker feature, but something that the FreemarkerServlet puts into the data-model, and something that requires Servlet environment and a HTTP request (as JSP requires that). Out of the box, there's no way to separate this feature from the FreemarkerServlet. However, maybe you can extend it so that you can still use it for your purpose. Most of the magic happens inside createModel, where among others, it adds JspTaglibs to the data-model.
It might also useful to know that FreeMarker (and thus FreemarkerServlet) can load templates directly from the database, if you give it a such TemplateLoader implementation through the FreeMarker Configuration. If all you want is serving templates from the database instead of where Struts traditionally stores them, you just need to provide the proper TemplateLoader.
