Error while creating web service using apache CXF wizard - cxf

I am creating a web service through the apache CXF. but while i proceed(before the wsdl gets created), i receive the following error
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/cxf/tools/java2wsdl/JavaToWSDL
This seems like the java2ws.bat file has some error.
The statement in the bat file is
"%JAVA_HOME%\bin\java" -Djava.endorsed.dirs="%CXF_HOME%\lib\endorsed" -cp "%CXF_JAR%;%TOOLS_JAR%;%CLASSPATH%" -Djava.util.logging.config.file="%CXF_HOME%\etc\logging.properties" org.apache.cxf.tools.java2ws.JavaToWS %*
It seems like at Run time,jvm is not able to find the CXF.jar.I added it in the classpath but still the same error
please help me to solve the issue

The problem arises while creating JVM. You can refer : Java Refuses to Start - Could not reserve enough space for object heap
It solved my problem.

Solr 4 Data Import Handler doesn't work

I am deploying Solr 4.3.0 in Tomcat 7.
Everything works fine but DataImportHandler. I can go to the
http://localhost:8080/solr/#/collection1/dataimport//dataimport
screen and see the dataimport options load at the UI.
Still, I can see any of my entities load in the "entity" combo box. Inside the configuration box, at the right side I can see the error below.

note The full stack trace of the root cause is
available in the Apache Tomcat/7.0.41 logs.Apache Tomcat/7.0.41
Problem is that I have the "log4j-1.2.16.jar" loaded in the classpath (it's on Tomcat lib dir).
Anyone have stepped in this problem?
Try following the steps outlined in Using the example logging setup in containers other than Jetty. I have encountered this same error when running Solr 4.3 until I followed these steps to configure logging.
After changing the directory, did you change the directory path in solrconfig.xml file.
I just want to make sure after the making changes in configuration file, did you restart the tomcat and solr server?
You need to copy the slf4j-log4j12-1.6.6.jar from the ext of Solr into the lib folder.
You also need to put the logging.properties file there.

ClassNotFoundException with Netbeans and H2 Database

So I followed the tutorial on the H2 Documentation page and used the "Connecting to a Database using JDBC" method of connecting to the database. I First added the h2-*.jar file to the Lib Folder (through Netbeans) and used the following to make the connection to my database I previously created.
Class.forName("org.h2.Driver");
connection = DriverManager.getConnection("jdbc:h2:~/" + DatabaseName);
This turned out to work in the IDE environment, however when I attempted to run the application directly from the jar executable I get the following error:
java.lang.ClassNotFoundException: org.h2.Driver ...
this error occurs at the Class.forName() class loader. So I did a little looking around and found that this was a prominent problem. One solution people use was to extract the class Loader from the current Thread as so:
Thread t = Thread.currentThread();
ClassLoader cl = t.getContextClassLoader();
cl.getClass().getClassLoader();
Class toRun = cl.loadClass("org.h2.Driver");
Unfortunately this seems to still result in the same error, so i'm wondering what i'm doing wrong. Should I be doing something to make sure the Driver is in the class path? I have no I idea how if that's the case.
Thanks!
You need to add the h2-*.jar file to the classpath when running the application, for example using
java -cp h2*.jar -jar yourApp.jar

NoClassDefFoundError MimeTypeException with PDF extraction

I am getting an exception trying to use update/extract with PDF files
My Set up is:-
Ubuntu Server 11.10
Tomcat 6
Solr 3.5.0.2011.11.22.15.54.38
I can browse to solr/admin OK
I have put all the contrib/extract and apache-solr-cell3.5.0.jar libraries into the tomcat folder webapps/solr/WEB-INF/lib
I am calling extract using:-
curl "http://localhost:8080/solr/update/extract?uprefix=attr_&fmap.content=attr_content&commit=true" -F "file=/path/to/my.pdf"
error is
java.lang.NoClassDefFoundError: org/apache/tika/mime/MimeTypeException
at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Class.java:264)
at org.apache.solr.core.SolrResourceLoader.findClass(SolrResourceLoader.java:383)

Would appreciate any pointers - the only time this error seems to come up elsewhere is with Nutch and cached results.
I have tried sending the mimetype in the querystring and also a *.doc file but got the same error.
According to the error message it is not a MimeTypeException exception you get: The problem is a NoClassDefFoundError, because Solr cannot load the class MimeTypeException.
Normally this class is present in tika-core.jar.
Make sure you actually have that file and also check if you have a lib statement in your solrconfig.xml pointing to the right directory.
This was due to the basic error of copying the necessary tika libraries (to tomcat6/webapps/solr/WEB-INF/lib) but leaving ownership of the jar files as ROOT instead of chown-ing them to TOMCAT6. After setting the right permission and restarting Tomcat it started working OK
Found the solution of this problem, I was using SolrJ to update my pdf indexing.
after deploy solr to tomcat, I didn't include the following libraries into the tomcat/webapp
and I get all the lazy loading problem, etc etc
I even try to get apache tika...
until I do this...
shutdown tomcat
\apache-solr-3.5.0\contrib\extraction
copy the libraries above to below
\apache-tomcat-7.0.26\webapps\solr\WEB-INF\lib
startup tomcat
cheers

Is JRebel necessary to run Maven?

Greetings,
I am trying to start a scala/liftweb project for deployment on Google App Engine. To do this, i need to package it up as a .war using maven.
However, whenever I run the 'mvn' command, I am met with:
Error opening zip file or JAR manifest missing : /Applications/JRebel/jrebel.jar
Error occurred during initialization of VM
agent library failed to init: instrument
Is there something wrong with my maven or do I need Jrebel? I see jrebel is not free which is why I am so surprised.
thanks!
No, JRebel is definitely not required to run Maven.
As Matt mentioned, JRebel is not required to run Maven. However, ZeroTurnaround does offer a free version that works with Scala. You can get it here:
http://sales.zeroturnaround.com/
As for your error - it indicates you are trying to start the JVM as though you are using JRebel. What is the full Maven command you are running? What is in your MAVEN_OPTS environment variable? If either of them contain something like -noverify -javaagent:/Applications/JRebel/jrebel.jar, then that's your problem.
One of the reason of the problem is a blank in the path of jrebel.jar
Make sure that there is no blank in the path like in "Program Files"

WSDL2Java tool error Apache CXF

We get the following error when we use WSDL2Java tool to generate stubs. The webservice is up and running.
WSDLToJava Error: org.apache.cxf.wsdl11.WSDLRuntimeException: Fail to create wsd
l definition from : http://scheduler.heartbeatsoftware.com/scheduler/WebServices
/SampleSNMWebService?wsdl
Caused by : WSDLException: faultCode=PARSER_ERROR: java.lang.IllegalArgumentExce
ption: InputSource must have a ByteStream or CharacterStream
If we donwload the wsdl and generate stubs from that wsdl, they are generated. But the java client using those stubs throws the same exception as above
Strangely when we deploy the same webservice on our LAN such a problem is not encountered stubs are generated sucessfully and the subsequent java client works well.
The webservice is created using apache cxf version 2.2.5 and hosted on tomcat 6
Any pointers would be appreciated
regards
Sameer
Found solution. Just need to modify the wsdl.java.bat to include proxy settings
-Dhttp.proxyHost= -Dhttp.proxyPort=8080
