I'm having some trouble trying to include Apache POI poi-ooxml library to my project. I'm using Maven and the following dependency:
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>3.8</version>
</dependency>
But after doing this I'm not able to start my Spring MVC app again, Here is the stacktrace:
Exception created : org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from ServletContext resource [/WEB-INF/context/applicationContext.xml]; nested exception is javax.xml.parsers.FactoryConfigurationError: Provider for javax.xml.parsers.DocumentBuilderFactory cannot be found
So, what I understand is that poi-ooxml is including another xml parser that override the default Java VM defaut one that is used by Spring to read its xml configuration file.
If I exclude the 2 following libs:
xmlbeans
xml-apis
All is working fine (I'm able to start my Spring app) but of course Apache POI is no longer working as he's missing these 2 required libs...
Any advice will be greatly appreciated ;)
Thanks
I've had similiar problem after adding poi-ooxml to my existing groovy application. I've added xercesImpl to project, and it seems to be working. Maybe you should give it a try.
<dependency>
<groupId>xerces</groupId>
<artifactId>xercesImpl</artifactId>
<version>2.9.1</version>

i am having a Java EE project in which i include the Birt runtime as a maven dependency:
<dependency>
<groupId>org.eclipse.birt.runtime</groupId>
<artifactId>org.eclipse.birt.runtime</artifactId>
<version>4.6.0-20160607</version>

</exclusion>
</exclusions>
</dependency>
The engine seems to be created (i hope at least) . In my report i have defined the datasource settings.
<data-sources>
<oda-data-source extensionID="org.eclipse.birt.report.data.oda.jdbc" name="somename" id="43">
<list-property name="privateDriverProperties">
<ex-property>
<name>contentBidiFormatStr</name>

</ex-property>
<ex-property>
<name>metadataBidiFormatStr</name>

</list-property>
<property name="odaDriverClass">oracle.jdbc.driver.OracleDriver</property>

<property name="odaUser">username</property>
<encrypted-property name="odaPassword" encryptionID="base64">password</encrypted-property>
</oda-data-source>
</data-sources>
Unfortunately it seems that Birt cannot find the ojdbc driver (Note, we use an oracle database) and we get the following error:
SEVERE [org.eclipse.birt.data.engine.odaconsumer] (default task-20)
Unable to open connection.:
org.eclipse.birt.report.data.oda.jdbc.JDBCException: Cannot load JDBC
Driver class: oracle.jdbc.driver.OracleDriver.
I have included in my Web module under WEB-INF/lib the following jar org.eclipse.birt.report.data.oda.jdbc_4.6.0.v201606072122.jar but i am still getting the same error.
Is there any way to solve this by adding the ojdbc as a maven dependency or is there any other workaround ?
Update: I have tried to also to add the also the org.eclipse.birt.report.data.oda.jdbc_4.6.0.v201606072122.jar as a maven dependency.

I am getting the same error. Bellow some part of the stacktrace:

Update 2: I made further changes but still without success. I added the org.eclipse.birt.report.data.oda.jdbc_4.6.0.v201606072122.jar library in all my modules under WEB-INF and MEtA-INF
\src\main\webapp\WEB-INF\lib\org.eclipse.birt.report.data.oda.jdbc_4.6.0.v201606072122.jar
The results are quite the same:

org.eclipse.birt.report.data.oda.jdbc
I would also like to note here something. For our persistence in the application, we use a datasource on our wildfly in which we use the ojdbc driver as a module in Wildfly 10 .
I am slowly running out of ideas with Birt + ojdbc
Finally solved the problem. I had to install the oda jdbc driver in my local manen repository and add it as a dependency in my ejb module.
<dependency>
<groupId>org.eclipse.birt.ojdbc</groupId>
<artifactId>odajdbc</artifactId>
<version>4.6.0-201606072122</version>
</dependency>
Furthermore, for some reason which i cannot yet explain, Birt required also the ojdbc6 driver in my web module. I honestly cannot understand why, since the entire birt implementation and runtime is in the ejb module.
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc6</artifactId>
<version>11.2.0.4.0</version>
</dependency>
That solved the problem and now the reports are getting generated.
I am now facing two new problems which i have to solve.
1) java.lang.OutOfMemoryError: Java heap space : I found in Eclipse bugzilla that this problem can be solved with the ojdbc7 driver. The reports are not generated unless i push my servers -Xmx above 1400mb
2) [org.eclipse.birt.report.data.oda.jdbc.JDBCDriverManager] (default task-20) DriverClassLoader failed to load class: oracle.jdbc.driver.OracleDriver: java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver: For some reason i get this error only one time when i want to generate a report. The report is generated without problems and the exception never appears again.
At least the reports are working now and can continue solving the other issues.
i have created spring rest services using eclipse IDE. It works fine in eclipse when i run using Debug configurations however when I export it as a executable JAR and run using below command
java -jar cs.jar
it gives me below error:
org.springframework.context.ApplicationContextException: Unable to start embedde
d container; nested exception is org.springframework.boot.context.embedded.Embed
dedServletContainerException: Unable to start embedded Tomcat

why it's not working as a jar?
You need to check if you have included servlet-api jar in your classpath, if yes, delete it.
If servlet-api is in classpath, it is included in WEB-INF/lib and then the error is thrown because servlet container has already servlet api jar.
Delete servlet-api dependency from maven or gradle if exits or if this dependency is adding by any other module then exclude servlet api dependency like below
<dependency>
<groupId><groupId></groupId>
<artifactId><some dependency></artifactId>
<version><version></version>
<exclusions>
<exclusion>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
</exclusion>
</exclusions>
</dependency>
I'm building a web app using Vaadin and it needs to communicate with several REST APIs. I've set it up in IntelliJ with Maven. I was thinking for the REST client I would use GSON to parse the JSON objects I'd be receiving from the open APIs, however, the application crashes due to a servlet exception error.
Caused by:
java.lang.ClassNotFoundException: com.google.gwt.json.client.JSONObject
I've added the GSON dependency to the pom.xml:
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.3.1</version>
</dependency>
And have tried changing the module settings from Provided to Compiled to Runtime but with no change.
I'm just stumped as to why the GSON jar appears in the project dependencies within IntelliJ using Maven but fails on run time. I've seen references to Eclipse and including the jar in the classpath but, again, I'm using IntelliJ/Maven to build my Vaadin project and satisfy dependencies.
Any help is greatly appreciated!
Add below dependency in your classpath:
<dependency>
<groupId>com.google.gwt</groupId>
<artifactId>gwt-user</artifactId>
<version>2.3.0</version>
</dependency>
I have a Java EE project which is meant to run on Glassfish 4.1. I want to use Selenium to collect information from some web pages, i.e. I need to include Selenium in the deployment (not just for tests).
I am using Eclipse IDE and have previously utilized the incremental deployment function in Eclipse to automatically deploy all saved changes to the project. But when I included (with Maven) the dependencies for Selenium incremental deployment stopped working. The project can still be deployed to Glassfish but I have to restart Glassfish between every change. I get the following error in Eclipse:
Exception while loading the app : java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: java.lang.RuntimeException: com.sun.faces.config.ConfigurationException: java.util.concurrent.ExecutionException: com.sun.faces.config.ConfigurationException: Unable to parse document 'bundle://136.0:1/com/sun/faces/jsf-ri-runtime.xml': DTD factory class org.apache.xerces.impl.dv.dtd.DTDDVFactoryImpl does not extend from DTDDVFactory.. Please see server.log for more details.
org.apache.xerces.impl.dv.dtd.DTDDVFactoryImpl is included with Selenium as a transitive dependency (xerces:xercesImpl:2.11.0).
Here are my Maven dependencies:
<dependency>
<groupId>org.jboss.arquillian.selenium</groupId>
<artifactId>selenium-bom</artifactId>
<version>2.44.0</version>
<type>pom</type>
<scope>import</scope>
</dependency>
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-htmlunit-driver</artifactId>
</dependency>
I hope there is a solution to this but after reading Jens Schauder's response in Dealing with "Xerces hell" in Java/Maven? I'm afraid there might not be. Anyone?
I currently can't reproduce the issue with a simple project, did you make sure that you don't have any other dependencies which are importing another version of xercesImpl?
You can try to place the xercesImpl-2.11.0.jar and the transitive dependency xml-apis-1.4.01.jar in the lib folder of your Glassfish domain and exclude it from your dependencies like this:
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-htmlunit-driver</artifactId>
<version>2.44.0</version>
<exclusions>
<exclusion>
<artifactId>xercesImpl</artifactId>
<groupId>xerces</groupId>
</exclusion>
</exclusions>
</dependency>

I'm trying to develop a web application using following technologies JSF 2.0 , EJB 3, JPA, Maven.. It's based on MVC design pattern so I have 3 projects so far: one is an EJB project which contains business and model, the second one is the view part which contains JSF and all beans that will be used in JSF pages and the third one is an EAR projects used to unite previous project that I mentioned.
So far I made a simple app and the EAR Project was deployed successfully in JBoss 7 but whenever I try to access a page I get the following exception:
Servlet.service() for servlet default threw exception: java.lang.NoSuchMethodError: com.ocpsoft.pretty.PrettyContext.newDetachedInstance(Ljavax/servlet/http/HttpServletRequest;)Lcom/ocpsoft/pretty/PrettyContext;
I want to mention that I'm not so familiar with these technologies.
Please let me know if you want to give you additional info such as maven dependencies or whatever you think that it can cause this error.
I have the following dependencies related to prettyfaces:
<dependency>
<groupId>com.ocpsoft</groupId>

<dependency>
<groupId>org.ocpsoft.rewrite</groupId>

</dependency>
<dependency>
<groupId>org.ocpsoft.rewrite</groupId>
<artifactId>rewrite-config-prettyfaces</artifactId>
<version>2.0.11.Final</version>
</dependency>
I guess that the prettyfaces-core is missing, try to add this dependency :
<dependency>
<groupId>com.ocpsoft</groupId>
<artifactId>prettyfaces-core</artifactId>
<version>3.0.0</version>
</dependency>
I'm not sure about it, if it doesn't work, try the depedencies listed in the link below
