HtmlUnit Help

This is my first post in the forum. So I would also like to say hello to all. :)

I am currently developing an application for Android and to do so I came across HtmlUnit.
I have never heard of HtmlUnit so I decided to try it (me being the experimental type). I have come to an impasse.

"noclassdeffounderror". Its awful because I do not fully understand it. It is my first time even seeing this error.

Code:

---

public void showResults(String endText) throws Exception{
            WebClient webClient = new WebClient(); //ERROR IS HERE
            HtmlPage page = webClient.getPage(baseSite+endText);
            HtmlTable resultsT = page.getHtmlElementById("results");
            int i = 0;
            for(final HtmlTableRow row : resultsT.getRows()){
                    Toast.makeText(getApplicationContext(), "Getting Results...", Toast.LENGTH_SHORT).show();
                    for(final HtmlTableCell cell : row.getCells()){
                            results[i] = cell.asText();
                            i++;
                    }
            }
    }

What did I do wrong?

Do you get the error when compiling or executing?
Can you copy the full text of the message here?

I get the error while executing. There is no error while compiling. Thats why I am confused.

Full error:

By the way, thanks for the reply.

NoClassDefFoundError: com.gargoylesoftware.htmlunit.WebClient

Do you have the above listed class in a jar file that is on the classpath?

I have it in a library labeled HtmlUnit.
So yes.
Pic just to make sure:

Some how the JVM is saying it can't find the class???

Yeah I am confused as well.

No one can help me? :P
--bump--

Is the jar file with the missing class on the classpath?

Add something like the following to the main method to show what the classpath is.
Use the log or where ever you output debug info to output it vs println

Code:

---

      System.out.println("Classpath: " + System.getenv("classpath")
                          + "\n java.class.path=" + props.getProperty("java.class.path") );

---

Ok will do so.
Also noticed this in the beginning of my debug:

Code:

---


06-04 23:49:56.671: ERROR/dalvikvm(224): Could not find class 'com.gargoylesoftware.htmlunit.WebClient', referenced from method com.laytproducts.songmaster.mainAct.showResults
06-04 23:49:56.671: WARN/dalvikvm(224): VFY: unable to resolve new-instance 14 (Lcom/gargoylesoftware/htmlunit/WebClient;) in Lcom/laytproducts/songmaster/mainAct;

---

also, this is the results:

Code:

---


06-04 23:49:56.901: INFO/System.out(224): Classpath: null
06-04 23:49:56.901: INFO/System.out(224):  java.class.path=null

---

of this:

Code:

---

Properties props = new Properties();
        System.out.println("Classpath: " + System.getenv("classpath")
                + "\n java.class.path=" + props.getProperty("java.class.path") );

---

You need to set the classpath to include your jars and the directory containing your package root.

An excellent plumber is infinitely more admirable than an incompetent philosopher. The society that scorns excellence in plumbing because plumbing is a humble activity and tolerates shoddiness in philosophy because it is exalted activity will have neither good plumbing or good philosophy. Neither its pipes or its theories will hold water...

How do you put a class on the classpath in the Android environment?

I couldn't say - I guess they all have to go into the .apk file, but how that's done probably depends on your IDE. I've yet to dabble in Android development.
