Getting Noclassdeffounderror When Using Common.Lang.Stringutils in Android Java Code

Getting NoClassDefFoundError when using common.lang.StringUtils in android java code?

Yes, this because of your .jar file didn't import properly. Follow below steps -

1. Place your .jar file in your project's libs folder .

2. Import it into your project. And, GoTo project -> properties -> Java build path -> order tab.

3. Check, whether your .jar file checked and placed in order of 1st. This is the main thing.

Hope these steps helps you. Have a look at below image -

How to solve NoClassDefFoundError: Apache Commons Lang Android

Change your grade file to this:

implementation 'org.apache.commons:commons-lang3:3.6'

then you can use this import in your classes:

import org.apache.commons.lang3.StringUtils;

NoClassDefFoundError: org/apache/commons/lang3/StringUtils

I have added commons-lang-2.6.jar & commons-lang3-3.1-sources.jar...

Here's your problem: commons-lang-2.6.jar doesn't contain the org.apache.commons.lang3 package, since that's part of version 3, and commons-lang3-3.1-sources.jar contains the source code, not the byte code.

You need to include commons-lang3-3.1.jar instead.

java.lang.ClassNotFoundException: org.apache.commons.lang.StringUtils from BaseClassLoader

Your code seems to be using apace-commons-lang package .
Do add the jar from here http://mvnrepository.com/artifact/commons-lang/commons-lang/2.6.
Chek for the version you are using. Add the jar to your lib folder/classpath.

NoClassDefFoundError : org.apache.commons.lang.StringUtils

Check your version of commons-lang, mine was version 2.6
used sudo find / | grep commons-lang

add to the dependencies before plugins and ensure id starts with I not i:

<dependency> 
    <groupId>commons-lang</groupId> 
    <artifactId>commons-lang</artifactId> 
    <version>2.6</version>
</dependency> 

Does not build as per wiki there is no
controller/opendaylight/distribution/opendaylight/target
in order to ./run.sh
So I am looking for that now ??

StringUtils not found in Eclipse (java.lang.NoClassDefFoundError), although referenced as a library

When parsing HTML, you should use a HTML-parser instead of trying manualy to manipulate using string methods or regex. Among many, Jsoup is one of the best known and in my opinion the most intuitive and easiest parser you can use when working with HTML using Java. Look at this examples to get familiar with the selector syntax or/and read the documentation of the Selector API

Get the jar or dependency from Maven central jsoup 1.15.3

Using Jsoup and assuming you are interessted in the content of the table body of that page from your question, something like below should give you a starting point:

import java.io.IOException;

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.select.Elements;

public final class Example2 {

    public static void main(String args[]) throws IOException {
        Document doc = Jsoup.connect("https://www.tradegate.de/indizes.php?buchstabe=A").get();

        Elements tableRows = doc.getElementById("kursliste_abc").select("tr");

        tableRows.forEach(tr -> {
            String gattung    = tr.child(0).text();
            String bid        = tr.child(1).text();
            String ask        = tr.child(2).text();
            String stueck     = tr.child(3).text();
            String ausgOrders = tr.child(4).text();
            String change     = tr.child(5).text();
            String link       = tr.child(0).selectFirst("a").absUrl("href");

            System.out.printf("%-45s  %-10s  %-10s  %-10s %-10s  %-10s %-70s%n",
                              gattung, bid, ask, stueck, ausgOrders, change, link);
        });
    }
}
