Taglib: class not found in jar-file

I've got the following problem:
I whant to deploy a taglib to tomcat 5.0.25.
If I point to the jsp which uses the taglib I got the following error:
org.apache.jasper.JasperException: Unable to read TLD "META-INF/taglib.tld" from JAR file "file:/C:/Programme/Apache Software Foundation/Tomcat 5.0/webapps/taglibtest/WEB-INF/lib/gsa_prod3_db_taglib.jar": org.apache.jasper.JasperException: Failed to load or instantiate TagExtraInfo class: ch.gsa.prodass3.taglib.TagAddAttributeTEI
If I copy the taglib.tld out of the jar-file into WEB-INF and do the mapping in web.xml, I get this error:
org.apache.jasper.JasperException: Failed to load or instantiate TagExtraInfo class: ch.gsa.prodass3.taglib.TagAddAttributeTEI
root cause
java.lang.ClassNotFoundException: ch.gsa.prodass3.taglib.TagAddAttributeTEI
It seems like none of the files in the jar-file could be loaded.
Has anybody an idea?
Help would be very appreceated!
Greetings, Jonas

1 - double check the class is in the jar file, in that path, and is spelt correctly
2 - restart Tomcat
3 - check the contents of the tld file - particularly the extra-info tag and class name for it.

Problem deploying connector: META-INF/ejb-jar.xml not found in jar file

          Has anyone seen this problem:
          I built Sun's Blackbox implementation and packaged
          it identical to the BlackBoxNoTx.rar included with
          Weblogic's 'jconnector' sample (even using the same
          ra.xml and weblogic-ra.xml). When I try to deploy
          it, the server reports:
          java.io.FileNotFoundException:
          META-INF/ejb-jar.xml not found in jar file
          I have no idea why the server thinks my connector
          is an EJB. If I deploy the BlackBoxNoTx.rar included
          with the sample, everything works without a hitch.
          The only variable that I'm changing in my BlackBoxNoTx.rar
          is that I build the Blackbox classes myself--otherwise,
          the RAR packagings are identical. Any assistance is
          greatly appreciated since I'm banging my head against
          a wall...
          Thanks,
          -jason


          I was finally able to resolve this one. On the odd chance that someone else encounters
          the same problem, here's what went wrong:
          My RAR file had two directories: 'META-INF' and 'meta-inf'. The first was created
          by the jar tool and contained the manifest.mf file. The second I created manually
          and it contained my ra.xml and weblogic-ra.xml. When I examined the RAR using
          any tools or I extracted the contents, it looked like it only contained one directory:
          META-INF (because NT is case-insensitive).

Struts class not found for war file

Hello,

Hello Mark,
Your suggested solution (putting an empty commons-logging.properties into
web-inf/classes or in a jar in web-inf/lib)
does not make any change at all. It still complains about not being able to
preload the servlet and still
gives exceptions upong calling upon LogFactory.
What I have been able to do is put the three classes from
com.bea.wlw.netui.util.logging into a separate jar
and add that to web-inf/lib.
However I am sometimes getting funny exceptions upon undeploy
(NoClassDefFoundError for org.apache.commons.collection.FastHashMap$KeySet).
Regards,
Robert Varga

From a FAQ on netui:
1. Why do I get a ServletException while trying to deploy a struts web
application on a Workshop/Integration/Portal domain?
In the "<WL-HOME>/server/lib/knex.jar" file there is a properties file
called "commons-logging.properties" which configures the
com.bea.wlw.netui.util.logging.StrutsLogFactory class for Struts loggingas
below:
org.apache.commons.logging.LogFactory=com.bea.wlw.netui.util.logging.StrutsL
ogFactory
This class file is not available for a Struts web application that was not
built using Workshop, the reason being the containing NetUI jar files are
not present in the web application's WEB-INF/lib folder. This leads to a
ServletException while deploying the web application. The solution is toadd
a blank file (or a JAR containing the file) namedcommons-logging.properties
to the server CLASSPATH, or to the WEB-INF/lib folder of the concerned web
application. This issue will be fixed in Service Pack 2.
cheers

Hi Rob,
I also have a similar error with deploying a Struts web application into
a
8.1 Basic Workshop Domain created
by 8.1 Platform.
I get a ClassNotFoundException for 'com.wlw...StrutsLogFactory', whenStruts
tries to load any Jakarta class
from commons-beanutils or Struts which has logging.
This happens because commons-logging picks up some property whichinstructs
it to load that class, which is
naturally not included in most web applications, since it is
workshop-specific. This property definition, I think,
is in <bea>\weblogic81\server\knex.jar, called
commons-logging.properties,
containing the following line:
org.apache.commons.logging.LogFactory=com.bea.wlw.netui.util.logging.StrutsL
ogFactory
How can I override this in my webapp in a property file, so that when a
Struts or Beanutils class calls
LogFactory.getLog(org.apache.....<classname>.class), it would not try touse
the property file and the
class defined in knex.jar.
Thanks in advance,
Robert Varga

Actually it complained about a NoClassDefFoundError. Generally this
is
caused by something in a parent classloader that is found but then
depends on something only loadable in a child classloader.
eg.
You have something in your $CLASSPATH that references something in the
WEB-INF/lib. This will NoClassDefFoundError.
So, as I recommended, remove everything you've added to the$CLASSPATH,
add the jars to WEB-INF/lib. If you're still having problems, show me
your $CLASSPATH, the contents of WEB-INF/lib, and the error message
/stack trace.

Hello, Rob,
I did put the common-beanutils and other jar files in the

And from the weblogic console, I do see the jar file get included in

(those generated file name have some number attached at the end.)
As
I
mentioned
before, I can use javap find the class using this weblogic generatedclasspath.
But weblogic complained that the class is not found.

Class not found in jar

I have a servlet that is using request.forward() to invoke a class in a jar file.
This class is in the class path, as below. However, when that class runs, it cannot find other classes in that same jar file.
In my resin.conf file I have:
<web-app id='/test' app-dir='d:/apps/test'>
<classpath id='d:/apps/otherApp/WEB-INF/lib/otherApp.jar'/>
</web-app>
The jar file is in the web-inf/lib folder.
Running under Resin.
What do I need to do such that the invoked class will find it's fellow classes that are in the same jar file?

I don't see why
you would need to add that jar to the conf file.My web-app cannot otherwise find the target class. It is part of a different 'web-app'.
how did you create the jar?I didn't. This is a third party app. I cannot disturb the jar.
Due to the third party app, there are legacy issues that I am having to work around.
So my situation is like this.
c:/apps/app1
c:/apps/app2
c:/apps/app3
So, another servlet will contact app1. Depending on the 'POST'ed data, app1 will invoke either app2 or app3.
All code for app2 is in jars in WEB-INF/lib.

Classes not found for jars listed in manifest

I have an applet whose main jar has a number of dependent jars listed in the manifest. All the jars are signed.
The applet works fine when downloaded from an HTTP server.
Previous to 1.6.14 it would also run from a local directory.
As of Java 1.6.15 and 1.6.16, the classes in the dependent jars are no longer loadable from the local directory. ClassDefNotFound is the reported on the java console. Obviously the class is present, as the application is running fine in JVMs 1.6.14 and previous.
I see that 1.6.16 includes changes for the security baseline, but I cannot find anything that suggests changes are needed to support dependent jars. None of the dependent jars request a specific version of JRE.
Anybody know what is going on?

Is this the error? ...Yes, sorry, the exception is NoClassDefFoundError
If you provide a Short, Self Contained, Correct Example someone may be able to diagnosis the problem, as opposeed to guessing. A link to the real live application can be found at: http://download.equitrac.com/38834/InstallGUI.html. (This original application does not meet the definition of short ... but demonstrates the problem well.)
When run as an applet off this site, it works fine.
If you click on the download button, it will place a copy on your local harddrive. To execute it locally double click on your local copy of InstallGUI.html.
When running it locally with Java 1.6.15 and 1.6.16 it will give you a class def not found exception without doing any thing.
When running locally with Java 1.6.14, it will not experience any trouble.
This applet needs permissions to open sockets and store data on the harddrive.
Probably due to the presence of class files that once existed outside of the jars, but are now not thereClose ... the application is made up of a main jar (our product) and a number of third party jars. The manifest for the main jar properly references the other jars, and works in all JVMs before 1.6.15. As of 1.6.15, none of the classes from the referenced jars can be opened.
I found that I can work around the problem by placing all classes into a single jar ... which may infringe on licensing requirements for some of the third party jars we use.

Class not found in applet using 2 jar files

I have an applet which has been working for years as a stand alone or connecting directly to a derby database on my home server. I have just changed it to connect to MySQL on my ISP server via AJAX and PHP.
I am now getting a class not found error in my browser, probably because I'm stuffing up the class path.
The HTML I am using to call the applet is:
<applet code="AMJApp.class"
codebase="http://www.interactived.com/JMTalpha"
archive="AMJ014.jar,plugin.jar"
width="500"height="500"
MAYSCRIPT style="border-width:0;"
name="jsap" id="jsap"></applet>The AMJ014.jar contains the applet and supporting class files.
The error message is strange to me because it refers to a class I noticed on another web page but which has nothing to do with my applet. Anyway, the message in full is:

Access of MySQlL Driver class by eclipse but not from Outside Jar file

Dear All,
I have done a standalone application having access with MySQl database.
I could access it when i execute it from eclipse. But when i export it into Jar file and running I get MySQL Driver class not found exception.
Give me a better solution for this issue.

CLASSPATH, CLASSPATH, CLASSPATH.
You have defined the Eclipses Project Library Path to include the MySQL jar, but ar not including it on the classpath when executing the jar.
Either modify the MANIFEST.mf file in the jar to include a reference to the MySQL driver jarfile or call java in the following manner
java -cp /full/path/to/MySQL/Driver/jarfile.jar -jar yourJarFile.jarObviously, if this is on Windows and you are executing through a double click, the first option is the best option.

Class not found in web-inf/classes folder of war file within ear file

Hi all,
          I am using Weblogic 8.1 sp4. I have a war file within an ear file. I am trying to deploy the war file with a few classes within its web-inf/classes folder, however when the classes are in that folder I consistently get a class not found exception when trying to instantiate them. If I package the classes in a jar file and then put that jar file within the web-inf/lib folder of the war, the classes are also not found.
          If I put these two classes in the app-inf/classes folder of the ear file, everything works as expected and the classes are found.
          Any ideas of why this is happening. This seems to be a very simple thing that should work, but appears to not be working at all.
          thanks in advance for any suggestions or ideas.

Hi,
          This is a known limitation/issue with WL. There is also no way around this.

Main-class not found error while clicking on the jar

I have a created a jar �FinARM.jar� for my swing application using eclipse.
Clicking on this jar, it is giving the problem main-class not found.
It contains the MANIFEST.MF file, with entry Main-Class: FinAlignTest for the main class.
FinAlignTest is my main class.
I have a similar jar created with a small swing application (Single file) clicking on it can open the swing application.
It is also attached above.

Hi ,
My Apllication runs with out any warnings or errors. But when i create a jar file using eclipse it is giving this problem.
When i double click on the jar file i am getting this problem. MANIFEST.MF entry contains the main method entry.
I have created another jar (Which contains a simple java file, swing application) from eclipse export option.
It works fine on click.
But jar FinARM.jar contains 5 files (Swing app), which even fetch some data from the database.
My jar is placein the same machine where it can fetch data from DB
Can u plese tell me whats the problem.
-regards

Class not found: C:\Orcl\OracleXSU\lib\xmlparser.jar;

Hi,
I am testing out the XML functionality within Oracle 8i. I
downloaded XML SQL Utilities, modified the .bat files and run
it. The env.bat file ran fine, however, the oraclexmlsql.bat
file keeps giving me the message error:
"C:\ORCL\OracleXSU\lib>loadjava -resolve -verbose -
user "system/manager" xmlparse
r.jar
Class not found: C:\Orcl\OracleXSU\lib\xmlparser.jar;"
I added the xmlparser.jar in the classpath already.
I am running Oracle 8i, JDK 1.1.8 on NT 4.0 Server Machine. I
would appreciate any help I can get on this.

Hi Minh,
It could be because of case-sensitvity. Looks like your
directory is C:\ORCL\OracleXSU\lib whereas the error message
indicates C:\Orcl\... Please check that. (i.e. set the path to
C:\ORCL\ in the bat file and execute the bat file).
Also please check the xmlparser.jar file is indeed present in
the directory shown in the error message.
Also in the command line window in which you are running the XML
SQL, please verify the CLASSPATH settings by printing out the
CLASSPATH. e.g. set %CLASSPATH%.
Thx

Error in compiling: file javax\servlet\jsp\PageContext.class not found

Hi,
i'm getting an error when I'm trying to compile an java file. The error is as follows:
cannot access javax.servlet.jsp.PageContext
file javax\servlet\jsp\PageContext.class not found
Isn't the javax package included in jdk? I've installed jdk 1.3.1_03 and j2re1.4.0_02. Shouldn't this PageContext.class be automatically loaded when i've installed jdk?
I'm getting desperated! I've tried almost everything: i've changed the classpath, moved the directory of the java file I'm trying to compile over and over but i'm getting no success!
Any help is very welcome!
Thankx,
Nuno.

hmmm... i had a look and it seems that what you are trying to "import" is actually in a package... instead of import try:
package javax.servlet.jsp;you may need to go download this "package" and complile it in the directory you are working in.
my advice: try the above statement (which does compile for me), if it doesn't work, you will need to find the source code for this package and compile it just like you do any other source code.
hope this helps.

RT.JAR Files as mentioned in the Error log is not in the Directory ( you can verify)
Usually rt.jar is in
jdevbin\jdk\jre\lib.. Check the JDEV_USER_HOME variable and also the Libraries under Project Setting of JDEV , when you click on any specific lib it show you a path in the class path section..verify the same.
Thanks,

"Java Class not found in classpath" Error in DESIGNER

Hello All,
I'm trying to connect in Designer using a JDBC connection to MS SQL Server 2008. As per the instructions, I updated my jdbc.sbo file with the path to the existing two JAR files. However, I still get the following error when I try and connect in Designer: "Java Class not found in classpath : C:\Program Files\Business Objects\BusinessObjects Enterprise 12.0\win32_x86\dataAccess\connectionServer\jdbc\Drivers\sqlsrv". Of course, this error includes the drive path with the location to my JAR files. Any help in resolving this nagging issue is very GREATLY appreciated. Also, if anyone needs it I can post a copy of the jdbc.sbo file to this thread.
Thank you,
Pankaj

Stratos,
Your suggestion didn't help. I tried to connect after restarting my machine and I still get the error. And, I've also tried adding a connection to MS SQL Server 2005 using this JDBC driver, and that didn't help either. Any other suggestions? Would it help to see my "jdbc.sbo" file? Thanks again for your and everyone else's help, and I look forward to your reply.
Regards,
Pankaj
