I would like to set up an AppEngine service locally. Everything compiles, but when i try to run the project, I get this error:
SEVERE: Received exception processing C:\Users\eazyigz\Google Drive\Books\Android eBooks\Apress Practical Android Projects\PracticalAndroidProjectsSourceCode\Projects\08_GameService\war\WEB-INF/appengine-web.xml

See http://code.google.com/appengine/docs/java/config/appconfig.html#Using_Concurrent_Requests for more information.
You probably want to enable concurrent requests.

When I do enable threadsafe, Eclipse shows this compilation error:
I simply don't understand what is happening. Can somebody shed some light?
Thank you,
Igor
You should put <threadsafe> into appengine-web.xml file, not web.xml
You need to add true to the file "appengine-web.xml" instead of the "web.xml"

I'm working on setting up SearXNG using apache....ugh....btw, if anybody has any good instructions on this (besides the developer's website) I'd be very grateful.
In any case, after I configure the .conf file and restart apache2, it fails with errors saying this proxy module or that is an invalid command. From all the forums I've looked at, the suggestion was to a2enmod the modules it is complaining about, plus a few others. I've done that but apache keeps complaining about them.
I've not found a thread yet that speaks of this particular issue. Any ideas?
Thanks
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.

Chris Cashwell provided the correct answer. But for people like myself who are relatively new to Eclipse, here are more explicit instructions (which I came across here):
Right-click project directory in Project Explorer window
Select Run As > Run Configurations...
Go to Arguments tab
In VM Arguments textbox, add one of the following parameters mentioned by Chris:
-Dappengine.user.timezone.impl=UTC (this worked in my case)
-Dappengine.user.timezone=UTC
Click Apply then Run
In my case, this was done specifically in the context of a PlayN project I am working on, so I was right-clicking the HTML folder. In the end, my VM arguments looked something like this:
-Xmx512m -javaagent:/long/path/to/appengine-agent.jar -Dappengine.user.timezone.impl=UTC
See this bug report. For me, it was fixed by downgrading the JDK from 1.7.0_03 -> 1.7.0_02. Other things that have been purported to work are adding -Dappengine.user.timezone=UTC (or in some cases -Dappengine.user.timezone.impl=UTC) to the JVM flags.
i got this error, and found port already in use in the console.
I closed eclipse and killed javaw.exe. Then everything worked fine.
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

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
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"
