help for ClassNotFoundException
Hi , Under tomcat I am integrating the uPortal and running one portlet application in a web context. I put my own classes under the WEB-INF/classes directory and also put jar files in WEB-INF/lib directory , but I am getting the error : ClassNotFoundException , When I put these jar files in tomcat/common/lib directory , its working fine. Can anyone tell me That how and where I can specify for a web application under one context that where are the jar And class files. Qaiser Mehmood
ClassNotFoundException in thread
Hi all, I've just migrated my appservers from HP-UX to Linux RedHat AS4, and I'm now stuck with a strange issue : I've 2 jar in the WEB-INF/lib directory (common.jar and statistic.jar). The common.jar contains a Watchdog that seek in the DB for job to run, start them, and those jobs are looking for classes by reflection to handle the process to be done. The statistic.jar package contains the classes that handle the process to be done. Everything was fin until I migrated. Now the jobs run OK but they fire a ClassNotFoundException as shwon : java.lang.ClassNotFoundException: com.nexans.statistic.client.model.send.intranet.handler.CreateFileProcedure at java.net.URLClassLoader$1.run(URLClassLoader.java:199) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:187) at java.lang.ClassLoader.loadClass(ClassLoader.java:289) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:274) at java.lang.ClassLoader.loadClass(ClassLoader.java:235) at com.nexans.common.alert.businessmodel.jdbc.AlertJobImpl.run(AlertJobImpl.java:466) at java.lang.Thread.run(Thread.java:534) The problem persists when I extract the classes in the jar into WEB-INF/classes. So now I don't know what to do next and where to search. Does anyone have an idea ? I'm using Tomcat 4.1.31+ mod_jk 1.10 (was using tomcat 4.1.30 and jk2 on HP-ux, but I quite sure the problem is not there...) with java version 1.4.2_07 Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_07-b05) Java HotSpot(TM) Client VM (build 1.4.2_07-b05, mixed mode) on RH and java version 1.4.1.03 Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1.03-030630-19:37) Java HotSpot(TM) Server VM (build 1.4.1 1.4.1.03-030630-22:07-PA_RISC2.0 PA2.0, mixed mode) on HP-UX Thanks in advance Cyril ZEKSER - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Thanks for your answer but : is there a static initialisation code in com.nexans.statistic.client.model.send.intranet.handler.CreateFileProcedure ? or static properties whose values are taken from other methods? If anything in the static initialisation of class com.nexans.statistic.client.model.send.intranet.handler.CreateFileProcedure throws an Exception, the class wil be considered as non-existent. (which is quite normal, sometinh that could not be create does not exist) In fact, there is one static property : private static Logger myLog = Logger.getLogger( CreateFileProcedure.class ); but, as you mentionned in another mail, the Log4j.jar is not in common. this jar is in WEB-INF/lib (i've double checked ... kindda paranoid no ? :-) The line that crashed is the following : Object jobClass = Class.forName( getClassName() ).newInstance(); where getClassName() returns com.nexans.statistic.client.model.send.intranet.handler.CreateFileProcedure The problem is when the Thread try to find the class, because a test JSP can execute this without Exception. What are the possible changes between the two platforms mentioned regarding threads ? (RHAS4 with JDK 1.4.2 and HP-UX11 with JDK 1.4.1). Java has enough memory, and is started in -server mode with -Xmx512m option. Both config files (from both platform) are identical - except of course the directories. I've though also of a ISO-xxx encoding instead of UTF-8 that could cause the problem, but not... This code is a year old, and was working fine in the old platform - that crashed unfortunately... so I had to migrate. Copying the JAR seems not enough to work properly.

SOLUTION : Réf. : Réf. : Re: Réf. : Re: ClassNotFoundException in thread
Yeepeh !!! I've found the solution : All I needed to do was changing the loading of the class by : Object jobClass = this.getClass().getClassLoader().loadClass( getClassName() ).newInstance(); //Object jobClass = Class.forName( getClassName() ).newInstance(); I guess the OS and the JVM behave differently from HP-UX to Linux, now the class is found in the Thread. I don't know why the previous code was working in the previous platform... If there is a better wy to write this, please tell me :) Hope this help others people...

ClassNotFoundException - common/lib works, shared/lib gets exception
So that I avoid already loaded classloader problems with jar's that front native library calls via JNI, I am following the pattern of putting the jars into shared/lib. However, I get a ClassNotFoundException. If I put this into CATALINA_HOME/common/lib, everything works fine. It's my impression, though, that one ought to put it into shared/lib. I've tried both CATALINA_HOME/shared/lib and CATALINA_BASE/shared/lib. This is on Tomcat 5.0.28. I have not changed CATALINA_HOME/conf/catalina.properties, which would imply that CATALINA_BASE/shared/lib should work. Any ideas what might be going awry? Thanks for you help. rich - Do you Yahoo!?

DbcpDataSourceFactory ClassNotFoundException
My webapp has a working JDBC DataSource configured in META-INF/context.xml. The JNDI how-to mentions that the default factory for TC-managed JDBC DataSources (i.e. those configured as a Resource in the config files) is org.apache.naming.factory.DbcpDataSourceFactory, but if I configure that as my factory param for my DataSource, I get a ClassNotFoundException, so I looked in my common, shared and server folders but couldn't find it in any of the classes folders or the jars...? If I eliminate the factory param altogether, the app works fine. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

ClassNotFoundException implementing new WebappLoader
Hello, I'm trying to implement and register a new WebappLoader implementation with Tomcat 5.0.19. I've created a subclass of the standard WebappLoader class. In addition, I have added the Loader element to my Context element with my new class name specified.

RE: ClassNotFoundException implementing new WebappLoader
Hi, Hmm... I'd guess it should go in the same repository as the normal WebappLoader, which is $CATALINA_HOME/server/lib. $CATALINA_HOME/server/classes should be functionally equivalent for unpacked classes, so it's strange you get the CNFE when you put your loader there. Try packaging your loader in a jar file and putting that jar in server/lib.

ClassNotFoundException Using shared/classes
I just wanted to post this info so that other users don't make the same mistake I made.I was attempting to use the catalina_home/shared/classes for some shared class files and was getting ClassNotFoundException. When I copied those files to the catalina_home/common/classes directory everything worked fine. I finally found the issue, which I didn't see documented anywhere: I created my myweb.xml file by copying either the admin.xml or manager.xml. The problem is that those files contain privileged=true. Once I reset that to false (or removed the parm), I was able to load the classes in shared/classes.

ClassNotFoundException
Hi! I am stuck with the following challenge. After some initial problems with my web application with regard to ClassNotFoundExceptions when trying to read blobs from a MySQL database which was caused by my lack of knowledge regarding the Tomcat class loading filosophy (which is explained very well in http://jakarta.apache.org/tomcat/tomcat-4.1-doc/class-loader-howto.html) I am stuck with the following: I started out with a web application that was fully selfcontained i.e. it did not use database or JNDI resources defined in the Tomcat container. So there was a mysql-connector-java.jar in the WEB-INF/lib of the web application and the classes were in WEB-INF/classes. While developing under Forte4J (SunONE Studio update 1, Tomcat v4.0.1, NetBeans, Windows2000) everything seemed to work fine. Then I deployed to a RedHat Linux 8.0 host running Tomcat v4.0.3 and I got the ClassNotFoundException. QUESTION: Can somebody explain - in terms of class loading - why I get the ClassNotFoundException when both the MySQL driver stuff and the web application are in the same class loader context (at least they are there from my point of view). Then I changed to running Tomcat v4.1.24 both on W2000 and RH 8.0 (with JDK 1.4.0_01), I redesigned my web application to use the Tomcat filosophy regarding JNDI and database resources and I still got the ClassNotFoundException, that is until I found the documentation about class loading... What I don't like much is that I have to move part of my web application code (the classes that are stored as blob in the database) into the container's common/lib directory. This causes deployment of my web application to be more difficult and makes my web application less portable. Of course I did NOT read all of the Tomcat documentation, so I will not say that I know all about the different ways to configure a web application in Tomcat, but sometimes a few words in the right direction helps me to focus. I'm off reading more of the Tomcat docs and hope for somebody out there to enlighten me ;-) Regards, Guus

Can you post the entire stack trace? Can you post your code that's reading the blob? What is the name of the class that not found, and is that class available in the WEB-INF/lib or WEB-INF/classes directory of your webapp? I tried what Sriram Narayanan writes in his message of 21 feb 2002 (put the mysql jar not only in the $CATALINE/common/lib directory but also in the $CATALINA_HOME/webapps/webapp name/WEB-INF/classes/lib directory) . This shouldn't be necessary. Put the mysql jar in one location, preferably WEB-INF/lib. Post the above details and hopefully we can help more.

ClassNotFoundException and FileNotFoundException
Question: Is there a tag I need to place in a config file, web.xml file, or somewhere else to allow an applet access to use/find data/class (non-servlet) files in a local (non-ROOT) WEB-INF subdirectory? Problem: For non-servlets or servlets that have dependencies on other local classes/files, I am not able to locate files other than servlets specified in the local WEB-INF/web.xml file. Files found in the webapps/ROOT/WEB-INF/lib and webapps/ROOT/WEB-INF/classes are being found and used by my server. So I am able to make an applet dependant on certain .jar .xml or .class files work if I place those files in the proper subdirectory under ROOT/WEB-INF . The applet will work if files are place in the same base local directory as the applets' .html file, but it will not work when placed in the local WEB-INF subdirectories. Example: Using: Windows2K Pro. SP3 ; Tomcat 4.1.18 ; Java 2 SDK, SE, 1.4.0 I have a file arc.war with a structure as follows: META-INF/ META-INF/MANIFEST.MF Time.html index.html WEB-INF/ WEB-INF/data/Time.xml WEB-INF/lib/ WEB-INF/lib/jcommon-0.8.0.jar WEB-INF/classes/ WEB-INF/classes/connectionServlet.class WEB-INF/classes/arcChart.class WEB-INF/web.xml I place the .war file into the webapps directory and it expands on startup assuming it hasn't already. index.html refers to the servlet connectionServlet returning html and having no dependencies. This servlet works.

RE: ClassNotFoundException and FileNotFoundException
Howdy, Question: Is there a tag I need to place in a config file, web.xml file, or somewhere else to allow an applet access to use/find data/class (non-servlet) files in a local (non-ROOT) WEB-INF subdirectory? No such option exists: it would be a violation of the servlet specification for an applet (or a browser) to directly access anything under the WEB-INF directory. If an applet needs a certain jar, you need to place that jar outside the WEB-INF directory.

ClassNotFoundException JMX related?
I'm trying to create an MBean from within a Servlet with Tomcat 4.1.10 and I keep getting a ClassNotFoundException. The class in question is in the classpath and it's visible from the Servlet trying make the createMBean call. I've tried putting the the jar which has the MBean .class file in these places: a.. webapps/webapp_name/web-inf/lib b.. shared/lib c.. common/lib None of them worked. Creating this same MBean worked fine in Tomcat 4.0.x when I included the jmxri.jar in the webapp classpath. Does anyone know how to modify the classpath used by the JMX component of Tomcat 4.1.x?

RE: ClassNotFoundException
I don't' believe what you are trying to do is possible. Class loaders are created in a hierarchical manner with the children knowing about their parents, but not the parents knowing about the children. This makes it impossible for the current class loader (using Class.forName) to find the class file loaded by a child class loader (which the WEB-INF is). I see that you have three options: 1. Engineer another solution to your problem 2. Move MyServletClass into common 3. Move MyBaseServletClass into all the WEB-INFs. Personally the order of approach I would take is 3, 2, and then 1.

ClassNotFoundException
Hope someone can help: I have a TOMCAT app containing a servlet as follows: TOMCAT_HOME/webapps/MyApp/WEB-INF/classes/com/mycomp/MyServletClass.cl ass This class extends a base class that provides common functionality for all of my apps, and is stored in: TOMCAT_HOME/common/classes/com/mycomp/MyBaseServletClass.class (which extends HttpServlet) Through some context information, the MyBaseServletClass receives the classname of a class stored in my app's classes directory, which it is responsible for creating an instance of, using Class.forName(). This is the path of the class to be created: TOMCAT_HOME/webapps/MyApp/WEB-INF/classes/com/mycomp/MyOtherClass.clas s When the MyServletClass calls Class.forName, it fails with a ClassNotFoundException, but if I move the MyServletClass to the MyApp/WEB-INF/classes path, everything works fine. What gives? I thought that Tomcat reads adds the classes directory for all of the apps deployed in the server.xml (with Context info), which I defined as follows: Context path=/MyApp docBase=MyApp debug=0 reloadable=true / Thanks, Ken Ramirez - Principal/CTO [EMAIL PROTECTED] Master-Mind Consulting Services http://www.mastermind.com http://www.mastermind.com/ Ph - 570-688-9600 Fx - 208-275-2301
Apparent ClassLoader, ClassNotFoundException when using Apache Soap and Toplink
Tomcat 3.2 on NT 4.0. Apache Soap 2.2, http://xml.apache.org/soap/ Toplink 3.0.5 The root of this entire problem seems to be that the Apache Soap services/classes cannot be found, ClassNotFoundException, unless the classes are explicitly in the classpath tomcat.bat, startup, classpath. So says the installation notes. Now, make sure you have the jar files from the lib directory of this distribution on your classpath and start up tomcat. Also, you will want to have on the classpath any of your code that you want to deploy as services http://xml.apache.org/soap/docs/index.html This is a problem when using a package such as Toplink, which requires these classes to not be in the classpath because the webapp cannot find them. The object, 'com.cis.business.AddressModel' of class, 'class java.lang.String' could not be converted to 'class java.lang.Class', INTERNAL EXCEPTION: java.lang.ClassNotFoundException: This makes sense, the webapp classes should not have to be in the tomcat path. What if there are conficts between two apps. These classes should be in the webapp path, as Toplink assumes. Given these restictions, we cannot recieve a transaction through soap, and insert it into the database. Bottom Line: With soap classes in the classppath, it can't find our business object classes which aren't in the path. With soap classes in the classpath and our business objects in the path, it still cannot find the business objects because of Toplink problems. Without soap classes in path, it can't find the soap services. That said, I'll do what I have to in order to get this to work. Anybody know how? or have any suggestions other than prayer.

RE: ClassNotFoundException
I have the same problem under 4.0.1 and the reason I posted this to the Tomcat group was that the exact same website with absolutely no changes works on the Solaris box. And the class not being found is actually a JINI bass class that I use in multiple other non web based apps on NT with not problems. Thanks again for at least looking:) guess I'll just have to make sure I deploy on Unix boxes for the time being.

RE: ClassNotFoundException when using war file (Tomcat 3.2.3)
So far, I haven't had any fundamental problems with using jar files in WEB-INF/lib, though there can always be issues. For example, in Tomcat 3.2.x, there are problems if your web app wants an XML parser different from the one being used by the server. There is one very big difference between Tomcat 3.x and Tomcat 4.x with respect to class loading. Tomcat 3.x follows the JDK behavior where classloaders delegate to their parent classloader first before searching their own classes. Tomcat 4.x follows the recommendation in the Servlet 2.3 spec that classloaders search their own classes first before delegating. It is possible your web application is happier in this latter environment and needs some work to get it to work in the former.

RE: ClassNotFoundException when using war file (Tomcat 3.2.3)
I have found that WinZip always displays WEB-INF as Web-inf when viewing the contents of a WAR file. It doesn't seem to cause a problem when the WAR is expanded. It is incorrect to see extra directories created under WEB-INF/lib. This suggests that the WAR is packaged incorrectly. I can't tell what might be wrong from the information available so far. You can use the supplied WAR files as examples of what a WAR internally might look like. Note that Tomcat 3.2.x will not overwrite a web application directory if it already exists. You have to delete the directory first and then restart Tomcat 3.2.x to have the WAR file re-expanded. For those using Tomcat 3.3, you can avoid needing to delete the directory by adding redeploy=true to the AutoDeploy module in the server.xml. When Tomcat is started, it will re-expand the WAR file. Also, if the ReloadInterceptor is present, which it is by default, updating the WAR file while Tomcat is running will trigger redeploy and restart the web application the next time it is accessed.

I did the following based on the inputs I received (thanks for replying), however, I am still not successful in getting it to work * I made sure that the web-inf directory was in upper case (WEB-INF). * Winzip shows that all the jar files are in WEB-INF/lib/ directory. But for some reason winzip shows the web.xml file is in web-inf/web.xml although when extracted it the file is in WEB-INF/web.xml. Is this wrong ?? * When checked using winzip, I do not see the empty sub directories under WEB-INF/lib. However, when running tomcat, these empty sub directories gets created.

RE: ClassNotFoundException when using war file (Tomcat 3.2.3)
The WEB-INF directory is where web.xml belongs, so that is correct. It is likely that it isn't Tomcat, but something in the web application itself that is creating the empty subdirectories under WEB-INF/lib. /examples/addressbook/ doesn't ring any bells with me. It does seem like a strange place to be creating new directories, though. As far as the ClassNotFoundException, you will need to supply more information about the error before there will be much chance of determining the problem. A stack trace wouldn't hurt.

It is incorrect to see extra directories created under WEB-INF/lib. This suggests that the WAR is packaged incorrectly. I can't tell what might be wrong from the information available so far. You can use the supplied WAR files as examples of what a WAR internally might look like. Note that Tomcat 3.2.x will not overwrite a web application directory if it already exists. You have to delete the directory first and then restart Tomcat 3.2.x to have the WAR file re-expanded.

RE: That annoying ClassNotFoundException again
I haven't yet played with JDK1.4 yet. However, comments I have heard suggest that it may come with an XML parser built in.

JAR files in the $CATALINA_HOME/server/lib directory are visible only to internal Catalina classes. Because JDBCRealm lives inside Catalina, this is necessary in order to use an Oracle database. If you want to make your JDBC driver visible to web application as well, make another copy of classes111.jar in the $CATALINA_HOME/lib directory. Alternatively, you can include classes111.jar inside the /WEB-INF/lib directory of each web app that needs it (some drivers won't work when installed globally -- I haven't tried the Oracle one so I don't know about it specifically).

(application library) ClassNotFoundException
I've been running Tomcat 4.0b5 since it was released and had the JDBCRealm
stuff working just fine. I've been using Oracle 8.1.7 (8i) on Linux RedHat
6.2. I upgraded just recently to RedHat 7.1 and Oracle 9i (9.0.1) and tried
to get my application working again but it is failing on the JDBCRealm
initialization. Specifically, the first call to open() fails with a
ClassNotFoundException for the oracle JDBC driver. The relavent part of the
server.xml file is
Realm className=org.apache.catalina.realm.JDBCRealm debug=99
driverName=oracle.jdbc.OracleDriver
connectionURL=jdbc:oracle:thin:@castor:1521:orasid9i
connectionName=opf connectionPassword=opf
userTable=opf_user_cred userNameCol=user_name
userCredCol=password
userRoleTable=opf_user_roles roleNameCol=role_name
digest=MD5
/
The only change I made for 9i was to change the driverName from
oracle.jdbc.driver.OracleDriver to oracle.jdbc.OracleDriver as recommended
by Oracle. In my application lib directory I made a link to the classes12.zip
(and .jar file) and rebuilt. I've confirmed that the classes12.{jar,zip}
files are in
/usr/local/jakarta/jakarta-tomcat-4.0-b5/src/build/webapps/opf/WEB-INF/lib/

Re: (application library) ClassNotFoundException
Hey Mike,
Your advice helped immensely. Can you help me with this one too, we use
HTTP Apache based authentification. So we need to pass a HREF in HTML with
the syntax username:password@URL. But thing is, this URL is a JSP page that
invalidates the session of a USER. So what we did is call the JSP page in
the URL, and redirect in that JSP page with the username:password. You
cannot put this information in the redirect JSP command or forward. How
would I solve this?

Tomcat3.2.1 -ClassNotFoundException error when using Third-party libraries
Hi there:
I'm having the following configuration and I'm using mod_jk instead of mod_jserv and
starting Tomcat using startup.sh script provided.
Tomcat 3.2.1+Apache1.3.9+Sun Solaris2.7
I have a servlet (TopicServlet) which is using a thirdparty library(PANJA.jar). When
I'm running the same code but using main() I could be able to get the code work but
when I tried to run it as a servlet I'm getting the following error.
I could reach the servlet (configured server.xml and web.xml) and even put PANJA.jar
in WEB-INF/lib of Tomcat. Also I included it(PANJA.jar) in CLASSPATH while running the
startup.sh srcipt.
I don't know where I'm going wrong. Please help.
PS: PANJA.MtClass.mtInitializer(MtClass.java:163) - I'm calling MtClass's
mtInitializer("Topic"). Topic and TopicList are my classes.
Thanks,
Srujan

ClassNotFoundException
I've new to servlets and jsp and have just installed Tomcat so forgive me if I'm missing something really simple here. I've searched the archives and not found any answers. I've created a new webapp as detailed in the instructions that I downloaded. The servlets and html files work fine but when I try to load a jsp the browser diplays a 404 error and I get a ClassNotFoundException in the command window. I'm running Tommcat 3.2.1 with Linux/Apache. Can anyone help me out. Michael Garthwaite

Re: ClassNotFoundException
Michael, I had a problem similar to this tonight. After a little searching I found out that it was related to classpath. Make sure your classes folder is in your classpath.
