Probably got a version mismatch on `xmlbeans` in pom.xml when accessing Excel File

I got this error:
java.lang.NoSuchMethodError: 'org.apache.xmlbeans.XmlOptions org.apache.xmlbeans.XmlOptions.setUseDefaultNamespace(boolean)'
when using the following xmlbeans Version in pom.xml:
<dependency>
<groupId>org.apache.xmlbeans</groupId>
<artifactId>xmlbeans</artifactId>
<version>5.0.3</version>
</dependency>
I have excluded the xmlbeans from the dependency of poi, poi-ooxml and poi-ooxml-schema.
How to get rid of the error message?
I expect to load Excel file via fileInputStream as follows:
workbook= WorkbookFactory.create(fileInputStream);

How do I solve this below exception I get when converting docx to pdf using Documents4j library?

I am using the below code to convert docx to pdf.
public static void main(String[] args) {
File inputdocxfile = new File(System.getProperty("user.dir") + "/src/test/resources/files/output/");
File outputpdffile = new File(System.getProperty("user.dir") + "/src/test/resources/files/output/"
+ "CustomerOutputdocx.pdf");
IConverter converter = LocalConverter.builder().baseFolder(inputdocxfile)
.workerPool(20, 25, 2, TimeUnit.SECONDS).processTimeout(5, TimeUnit.SECONDS).build();
Future<Boolean> conversion = converter.convert(inputdocxfile).as(DocumentType.MS_WORD).to(outputpdffile)
.as(DocumentType.PDF).prioritizeWith(1000).schedule();
}
and I am getting this below exception. I am using the same code as mentioned in the documents4j official website.
Exception in thread "main" java.lang.IllegalStateException: The application was started without any registered or class-path discovered converters.

I had missed few dependencies and I also had to use a newer version of commons-io. I previously used commons-io 1.3 but later I came to know that Documents4J uses commons-io 1.4 or later and when commons-io version was changed it worked. And If anyone wants to know the dependencies I used to convert docx file to pdf in java. These are the ones.
<dependency>
<groupId>com.documents4j</groupId>
<artifactId>documents4j-api</artifactId>
<version>1.0.0</version>
</dependency>
<dependency>
<groupId>com.documents4j</groupId>
<artifactId>documents4j-local</artifactId>
<version>1.0.0</version>
</dependency>
<dependency>
<groupId>com.documents4j</groupId>
<artifactId>documents4j-transformer-msoffice-word</artifactId>
<version>1.0.0</version>
</dependency>
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>2.4</version>
</dependency>
<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>18.0</version>
</dependency>
And let me remind you. This library works only on machines which have MS Office installed in it; as the library uses the application itself to convert docx to pdf. If someone is hosting this code on a server there is also a remote converter which you can use instead of the Local converter as shown here.

I've added commons-lang-2.6.jar & commons-lang3-3.1-sources.jar in libs and classpath
Main class:
public static void main(final String[] args) throws CardException {
Main pcsc = new Main();
CardTerminal ct = pcsc.selectCardTerminal();
Card c = null;
if (ct != null) {
c = pcsc.establishConnection(ct);
CardChannel channel = c.getBasicChannel();
PcscProvider provider = new PcscProvider(channel);
EmvParser parser = new EmvParser(provider, false);
parser.readEmvCard();
c.disconnect(false);
}
}
I have referred to the following links:

http://apache-commons.680414.n4.nabble.com/lang-java-lang-NoClassDefFoundError-org-apache-commons-lang-StringUtils-Exception-td3735881.html

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.

If you're using Maven, put this inside your pom.xml file:
Maven Central Repository for Commons Lang:
<dependency>
<groupId>commons-lang</groupId>
<artifactId>commons-lang</artifactId>
<version>2.6</version>
</dependency>
Maven Central Repository for Apache Commons Lang:
<dependency>

<artifactId>commons-lang3</artifactId>
<version>3.12</version>
</dependency>
Don't forget: Update Maven Project

Yo adding the below and update maven project worked like a charm:
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-lang3</artifactId>
<version>3.1</version>
</dependency>

Adding below worked for me:
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-math3</artifactId>
<version>3.6.1</version>
</dependency>

When everything else is correct, rarely jar file gets corrupted. Ensure you don't see error something like below while compiling
[ERROR] error reading
C:\Users\Mohan\.m2\repository\org\apache\commons\commons-lang3\3.7\commons-lang3-3.7.jar;
ZipFile invalid LOC header (bad signature)

I was having this issue in IJ version 2016 after updating it to 2018.3.4 and clicking "Generate sources and update folders for all projects" at Maven options tab the issue went away

com.google.api.client.json.jackson.JacksonFactory; missing in Google Drive example

I tried running the quickstart-sample, and this dependency:
<dependency>
<groupId>com.google.apis</groupId>
<artifactId>google-api-services-drive</artifactId>
<version>v2-rev78-1.15.0-rc</version>
</dependency>
from Drive wiki API page
Yet when I try to compile the code com.google.api.client.json.jackson.JacksonFactory; is missing.
To verify this you just need to do Step 2 & 3! Where can I find this class or how can I replace it in the sample?

Jackson library can be found
at http://repo2.maven.org/maven2/com/google/http-client/google-http-client-jackson/
For July 7, last version can be obtained by Maven
<dependency>
<groupId>com.google.http-client</groupId>
<artifactId>google-http-client-jackson</artifactId>
<version>1.15.0-rc</version>
</dependency>
You may also need
<dependency>
<groupId>com.google.oauth-client</groupId>
<artifactId>google-oauth-client-java6</artifactId>
<version>1.15.0-rc</version>
</dependency>

Use this class for JacksonFactory instead of the previous one.
com.google.api.client.json.jackson2.JacksonFactory

Since version 1.11, jackson library has been moved out to separate jar to provide developers better choice of versions of each library. Please check readme.html of zip file you downloaded from google-api-java-client and you can check which specific jar file you want to include in your project.

http://mvnrepository.com/artifact/com.google.api.client/google-api-client/1.4.1-beta
This dependency will solve your problem:
<dependency>
<groupId>com.google.api.client</groupId>
<artifactId>google-api-client</artifactId>
<version>1.4.1-beta</version>
</dependency>

For gradle.build =
compile group: 'com.google.http-client', name: 'google-http-client-jackson2', version: '1.11.0-beta'

Getting the same problem. We both must be playing with Solr 3.6
I had to download the HttpClient jars from the HttpComponents project. They didn't seem to be included with Solr 3.6
http://hc.apache.org/downloads.cgi
3.6 Has a new version of the client that uses the new HttpComponents (4.0) stuff, not the old HttpClient (3.1) stuff. The old 3.1 jar is there, but not the new one.
Once I copied the jars over, it worked.
I copied the following (not all may be needed).
httpclient-4.1.3.jar
httpclient-cache-4.1.3.jar
httpcore-4.1.4.jar
httpmime-4.1.3.jar
works for me, now.

If you are using Maven to include SOLRJ, you'll also want the following phrases in your POM:
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.2.1</version>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpmime</artifactId>
<version>4.2.1</version>
</dependency>

Looks like you are missing the HttpClient Jar file in your runtime classpath.

I was also facing this issue. To resolve this, I have done following:
Checked the versions available of http components in your "~.m2\repository\org\apache\httpcomponents" directory
Based on that add following entries in your pom.xml file and rebuild your project by running mvn clean install and mvn eclipse:eclipse command one by one.
(If you are behind the proxy, make sure you have provided essential configuration in your settings.xml file)
This should resolve the problem, It did for me. :)
