ClassNotFoundException:
org.apache.commons.lang.xwork.StringUtils with Struts2 - JSON - JQuery
| up vote1down votefavorite | I have a maven web project using struts2. It has 4 modules totally and 2 are web modules. All are working perfectly. In my JSP, I want to use JQuery ajax with JSON value returning. JQuery $(document).on('click', "#test_connection", function(event){
var form = $('#genericDatabaseLoad');
$.getJSON('checkDBConnection', form.serialize(),function(data) {
$.each(data.connectionTestStatus,function(key, value){
alert("key "+ key + ", value " + value);
});
});
});stuts.xml <package name="json-default-package" extends="struts-default"> <result-types> <result-type name="json" class="org.apache.struts2.json.JSONResult"/> </result-types> <interceptors> <interceptor name="json" class="org.apache.struts2.json.JSONInterceptor"/> </interceptors> </package> <package extends="struts-default,json-default-package" name="checkDBConnection" namespace="/"> <action class="com.myconnenction.webapp.action.AAIDCADatabaseLoadAction" method="checkDBConnection" name="checkDBConnection"> <result type="json"></result> </action> </package> And JAVA method in Action Class public String checkDBConnection()
{
String driver=null;
String connectionURL=null;
Connection connection = null;
connectionTestStatus = new HashMap();
try
{
if(dbType.equals("mysql"))
{
driver="com.mysql.jdbc.Driver";
connectionURL="jdbc:mysql://"+hostname+":"+port+"/"+dbname;
}
Class.forName(driver);
connection = DriverManager.getConnection (connectionURL,username,password);
connectionTestStatus.put("status", "success");
}
catch(Exception e)
{
connectionTestStatus.put("status", "failure");
}
return SUCCESS;
}When I debug the project, the method is running and it returns SUCCESS and then showing me the following error SEVERE: Servlet.service() for servlet default threw exception

But I have added that in my pom.xml. <dependency>
<groupId>commons-lang</groupId>
<artifactId>commons-lang</artifactId>
<version>${commons.lang.version}</version>
</dependency>In the parent pom.xml, I have added <commons.lang.version>2.6</commons.lang.version> What is the problem? And how to solve this? json jquery maven struts2

activeoldestvotes| up vote2down vote | If you are really using commons-lang, the class should be org.apache.commons.lang.StringUtils instead of org.apache.commons.lang.xwork.StringUtils http://commons.apache.org/proper/commons-lang/javadocs/api-2.6/org/apache/commons/lang/StringUtils.html Update: add the following dependency: <dependency> <groupId>org.apache.struts.xwork</groupId> <artifactId>xwork-core</artifactId> <version>2.3.7</version> </dependency>

| up vote1down voteaccepted | I found the problem. The struts2-json-plugin version I was using 2.1.8 So in my parent pom I changed the version of struts2-json-plugin dependency to struts2-core version. <dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-json-plugin</artifactId>
<version>${struts.version}</version>
</dependency>And <struts.version>2.3.7</struts.version> Now it works perfectly.

| up vote1down vote | In my case it was struts-convention plugin, which needs to be set to same version as struts:<dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-convention-plugin</artifactId> <version>2.3.4.1</version> <!-- bugy version <version>2.2.1</version> --> </dependency I found all sorts of advices to add xwork-2.1.3.jar besides of xwork-core-2.3.4.1.jar but this only confuses the class loader, since this two jars have competitive set of classes.
