java.lang.Noclassdeffounderror: org/apache/Commons/httpclient/Httpexception

I’m having a problem using the library httpclient, the exception is happening:

Caused by: java.lang.Classnotfoundexception: org.apache.Commons.httpclient.Httpexception

I don’t know if I am also using the right library, I found that there are other libraries that treat the problem as the Apache Httpclient 4.3.6 API and Defaulthttpclient (which I think is from jboss). I use the Httpclient 3.1 API.

You are including all the libraries that come along with the Httpcomponents? For beyond the . jar HttpClient, there are several other dependencies as you can see in that image.

The Apache Httpclient 3.x is an old version and should be replaced skin Apache Httpcomponents.

Analyzing your settings I noticed that you mixed the two versions of the Apache libraries. Maven will bring incorrect or outdated dependencies.

Remove this entry from your pom.xml:

<dependency>
    <groupId>commons-httpclient</groupId>
    <artifactId>commons-httpclient</artifactId>
    <version>3.1</version>
    <scope>provided</scope>
</dependency>

In addition, I see in your Imports that your implementation is using the classes of the old version of the library. You probably picked up some example from the Internet and didn’t know this difference.

Look at the latest documentation and you’ll find something like this:

HttpRequest request = new BasicHttpRequest("GET", "/",
    HttpVersion.HTTP_1_1);

I suggest updating your application to the latest classes.
