JSTL, Tomcat & NoClassDefFoundError
Hi,
I am having a little problem with JSTL on my web hosting companies server.
My code works fine, until I put it on their server. I have copied their set up, ie. same version of java & tomcat onto my computer, and it still works fine here.
The only difference is that they are using Linux.
The error happens as soon as I insert a JSTL tag into a jsp page. ie:
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
<html>
<body>
<c:out value="Hello" />
</body>
</html>The first time I get a VerifyError:
java.lang.VerifyError: (class: org/apache/taglibs/standard/lang/jstl/JSTLVariableResolver, method: resolveVariable signature: (Ljava/lang/String;Ljava/lang/Object;)Ljava/lang/Object;) Incompatible object argument for function call
And on subsequent refreshes (until Tomcat is restarted) I get a NoClassDefFoundError:
java.lang.NoClassDefFoundError:org/apache/taglibs/standard/lang/jstl/Evaluator
Heres what I have done to attempt to resovle this so far:
- Use the Java SDK not JRE
- Put all the JSTL JARs into %TOMCAT_HOME%/common/lib
- Edit my classpath to include the current dir (.) and JSTL's standard.jar
- Then I added tools.jar & rt.jar to my classpath
Well i'm still getting the errors, and I can't figure out why. From what over people have said on the forums, it might be a classpath error... but I can't see how, as i've added the stuff i'm sure it needs to the classpath!
Any sugesstions will be greatly appriciated, I'm tearing my hair out!
My set up:
Tomcat v4.1.24
Java SDK 1.3.1_06
Linux on web hosting companies server, win2k on my machine
Thank you!

Hi,
I tried putting all the JSTL libraries in the WEB-INF/lib file, but it caused Tomcat to throw up loads of errors (in all set ups I tried) when it started. So by putting the JARs in common/lib I can avoid this. I did try your suggestion and just put the jstl.jar in WEB-INF/lib. It caused no errors on Tomcat startup, but didn't fix the problem either!
The JSTL tld's are definetely in WEB-INF/tlds and the web.xml file has the correct entries in it.
I suspect that it is a classpath error... or path.. or some kind of configuration like permissions or something.
Confused!

Servlet + Tomcat NoClassDefFoundError
Hi,
I am developing a servlet which takes data from Amazon's Web services (in XML format) and then outputs a RSS feed. I use xerces for parsing the XML and then use Rome to output the RSS feed. When I run the servlet then I get the following error.
However when I run the same code over the commandline, it runs fine, however running it as a servlet, it shows the NoClassDefFoundError . I am also sending the code , it contains the commented out System.out statements which I use when I am running it over the command line
Thanks
Gaurav

I am building the servlet for now in
$TOMCAT_HOME/webapps/examples/WEB-INF/classes ,
however there is no 'lib' directory in
$TOMCAT_HOME/webapps/examples/WEB-INF . I created one
and put the jar files there, but still I get the same
error. Infact when I start the server, I do not see
the jar file in CLASSPATH
Thanks
GauravYou shouldn't be putting your app in the examples directory.
You should create a directory under TOMCAT_HOME/webapps for YOUR individual apps. Each one should have a WEB-INF directory under that, and /classes and /lib under that. Your web.xml belongs in the WEB-INF directory. Your .class files, and their package directories, belong under WEB-INF/classes. 3rd party JARs, like JDBC drivers, belong in WEB-INF/lib.
The problem is that you don't know how to deploy a Web app properly on Tomcat. -
JSP useBean and Tomcat NoClassDefFoundError
Hi,
I have a webapp on tomcat whose structure is like this
/tomcat
--/webapps
----/mywebappname
------/WEB-INF
--------/classes
----------MyBean.java
When I use useBean class="MyBean" I get a NoClassDefFoundError for this particular class.
I suspect this is some kind of classpath issue but do not know how to fix it. Help appreciated.place u'r class file in <tomcat-root>/classes folder.
if there's no such folder ,u'll have to create it. -
hi,
i'm trying to install jwsdp 2 . i'm using tomcat 5.5 . but jwsdp2 is not recognizing tomcat 5.5 . it is looking for tomcat 5 or sun java application server. could you please tell what version of jwsdp is compatible with tomcat 5.5 . and where i can download it. in sun website on jwsdp 2 is available. i was looking to download jawsdp 1.3 but i cant find it anywhere. or jwsdp1.4 will do. just want to try. and see what works.
could someone explain me clearly about jstl. not the technical part. how to download what to use. there are may sites each site gives different procedure some say download from apache and some say download jwsdp from sun to install. are jstl from apache and sun same. what is the difference. what should i download. and what will be compatible with tomcat 5.5.
i tried downloading jstl from apache from this page http://jakarta.apache.org/taglibs/doc/standard-doc/intro.html
In tis page i selected link apache jakarta project mirror. i got some links like this
BCEL
BSF
Cactus
JCS
JMeter
Regexp
i thought these might different sites to download jstl .
i clicked on one of them. what i'm getting is something like jcs.zip or bsf .zip . i unzipped it. but there is no jstl.jar standard.jar . how to download these and where to?. i also downloaded sjwsdp2 from sun.but it is not installing it asking for tomcat 5 and i'm using tomcat 5. some please help me.user10257774 wrote:

There is a special Tomcat 5 for Java WSDP available here: http://java.sun.com/webservices/containers/tomcat_for_JWSDP_1_5.html
Don't forget to read the section on that page that says "Tomcat 5.0 for Java WSDP is not intended for deployment or production environments".

I know this is one of the jstl + tomcat problem again, but I need some help here. I think I've got everything right, but it seems Tomcat can't load the relevant class.

Help needed to run JSTL 1.1 in Tomcat 6.0.16
Hi All,Help needed to run JSTL 1.1 in Tomcat 6.0.16. I am trying to run the example given in http://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.html The example tries to connect to MySQL database from JSP using JSTL and JNDI Datasource.I am running the example using Eclipse 3.4.2 using Sysdeo plugin to start and stop Tomcat server from Eclipse IDE.
My web.xml file has <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
</web-app>
and test.jsp has proper taglib directives
<%@ taglib prefix="sql" uri="http://java.sun.com/jsp/jstl/sql" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
I have placed the jstl.jar and standard.jarof the jakarta-taglibs-standard-1.1.2.zip under E:\Deepa\workspace\DBTest\WebContent\WEB-INF\lib directory also placedcontext.xml file under E:\Deepa\workspace\DBTest\WebContent\META-INF and the content of context.xml is as below
<Context path="/DBTest" docBase="DBTest"
debug="5" reloadable="true" crossContext="true">
<Resource name="jdbc/TestDB" auth="Container" type="javax.sql.DataSource"

username="deepa" password="mysql" driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/javatest?autoReconnect=true"/>
</Context>
Now while running the example, Eclipse creates one DBTest.xml file under C:\Program Files\Apache Software Foundation\Tomcat 6.0\conf\Catalina\localhost
which has the following line:
<Context path="/DBTest" reloadable="true" docBase="E:\Deepa\workspace\DBTest" workDir="E:\Deepa\workspace\DBTest\work" />
I am getting the following error when running http://localhost/DBTest/WebContent/test.jsp

When running the same example, by creating a local server in Eclipse(creating new Server connection pointing to same Tomcat 6.0 installation) it runs fine without any error.Hi evnafets,
Wow, very helpful information, great insight into working of Eclipse. Thanks a lot.
I have one more question. I have a context.xml file under {color:#0000ff}E:\Deepa\workspace\DBTest\WebContent\META-INF{color} folder and that has the Resource element to connect to MySQL database:

Tomcat 5.5 or 6.0 + JSTL 1.2 - fmt:message doesn't work (for me :( )
I have trolled many forum posts and mailing list threads. I'm sure this question has been asked thousands of times (in fact I've read answers and tried to implement but come up short every time).
Q: How do you make fmt: message work with multiple bundle files?
I have simple test page test.jsp that includes a taglibs fragment. The page attempts to localize a key from a Messages bundle. I get the following as output:
???shoop???
This JSP has been deployed on Tomcat 5.5.23 and Tomcat 6.0.13 with the same result.
I have configured the web.xml many different ways, but currently it's per the 2.4 servlet spec. I have jstl-1.2.jar located in WEB-INF/lib. This is the only webapp library included my deployment. The rest is "vanilla" Tomcat.
I'm including the contents of the important files below.
What could be wrong?
test.jsp

------------------Hi all -
evnafets continues to grow his collection of platinum stars. :)
The trick was to set basename in fmt:setBundle to i18n.Messages.Messages. It's not clear from the tag's javadoc, but it appears that the convention is
path.to.bundledirectory.bundledefaultfilenamelessdotpropertiesextension
So, for me
since I have the following deployment structure
WEB-INF/classes/i18n/Messages
Messages.properties
Messages_en.properties
Messages_de.properties
I had to specify
<fmt:setBundle basename="i18n.Messages.Messages" var="msgBundle" />
<p><fmt:message key="shoop" bundle="${msgBundle}" /></p>
to finally see
shoop
If I add
<fmt:setLocale value="de" /> before all that
I get
der shoop-a-loop
Ha ha!
I would mention that it is not necessary to add the localizationContext in web.xml. It's a convenience if you don't want to specify the default bundle in your JSPs. You cannot define more than one bundle in your web.xml.
I am working with a webapp that has many different bundles, so I'll incurthe overhead of specifying bundle basenames and vars.
Thanks! -

Problem when use multiple c:import jstl on jsp on Tomcat 5.0
I have jsp that use multipe import jstl tag. I was able to run on the Tomcat 5.5.9. When I deploy it on Tomcat 5.0.28, it is not working.
For example:
<c:import url="/jsp/page1.jsp" />
<c:import url="/jsp/page2.jsp" />
I look at Tomcat cache directory and I only see page1.jsp compiled but not page2.jsp. I look at the catalina.out log file and the error message shows below. I thought JSTL is working for Tomcat 5.x up. Do anyone have any idea? Please help.
Thanks.

JSTL 1.1.2, TOMCAT 5.5, JDK 5, Eclipse and Problems
I have been having trouble loading the JSTL library (standard.jar & jstl.jar)
I'm using Eclipse 3.0.2 to do my development work on my JSP pages. So normally I will just create my Tomcat(5.5 on JDK5.0) project using Sysdeo(tm) plugin in its default directory (C:\eclipse\workspace\mytomcatproject).
Then I would begin creating my JSPs and use JSTL(1.1.2) for my development. I'd put those standard.jar/jstl.jar into /WEB-INF/lib as recommended.
The problem is I can't seem to get JSTL library working, even I tried out copy and pasting the example code into my pages.
I have :
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
... //some code
${fn:escapeXml(param["myreq"])} will show out in the JSP exactly "${fn:escapeXml(param["myreq"])}" without processing. Although no runtime errors comes out (meaning the TOMCAT successfully loaded the library) but seems that the taglib is not working!!!
I did some experiments:
Experiment 1 :-
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
(notice the uri, its without /jsp)
and it works for /core taglib, but not the /functions taglib. Meaning somewhere in the TOMCAT library it load the older 1.0 version of JSTL.
When I try using the /functions taglib
<%@ taglib prefix="fn" uri="http://java.sun.com/jstl/functions" %>
TOMCAT will complaint about the non-existence of this JSTL.
Experiment 2 :-
I tried to copy all the JSTL tld into my /WEB-INF/tld and and change my web.xml to include the tld location by using <jsp-config><taglib>.
Doesn't work as well!!! The taglib just didn't get process.
Experiment 3 :-
I tried to modify the <Context> in server.xml to include tldNameAware and tldValidation to TRUE.
Not Working as well!!!
Experiment 4 :-
I comment out the <my_tomcat_home>/conf/server.xml <Context> (the one that Eclipse created for my Tomcat project) and directly paste my project directory into <my_tomcat_home>/webapps and restarted my TOMCAT.
IT WORKS!!!
So does JSTL 1.1.2 only works in TOMCAT webapps home? Seems that TOMCAT only load the /WEB-INF/lib when the project is in its webapps, but when the project is outside of the webapps dir, it seems doesn't process the JSTL lib.
Any idea how to make it work outside the Tomcat webapps cause I try to encourage my team to use Eclipse and CVS.The probable cause of the issue is your web.xml file.
If your web.xml file is declared as being servlet version 2.3, then it disables the JSTL expression language (EL) by default.
ie if you have this:
<?xml version="1.0"?>
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>It should change to be this:
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">Undo all of that hacking you did through the config files.
JSTL needs no tld files, and no entries in web.xml to make it work.
Hope this helps,

JSTL, MySQL, Tomcat sql:query error
Hi to everyone...
This is my first post, but since im employed now as a java developer ill be here regulary.
Right now im trying to use the JSTL to make some simple sql selects in my JSPs....
Here�s the JSP code:
<%@ page language="java" import="java.lang.*,java.util.*" %>
<%@ taglib uri="/jstl-core" prefix="c" %>
<%@ taglib uri="/jstl-sql" prefix="sql" %>
<html>
<head>
<title> A first JSP database </title>
</head>
<body>
<sql:setDataSource scope="session" var="dataSource"
url="jdbc:mysql://127.0.0.1/zolltek" driver="com.mysql.jdbc.Driver"
user="root" password="root"/>
<!-- The following UPDATE works fine.. -->
<sql:update var="users" dataSource="${dataSource}" scope="session">
INSERT INTO test VALUES (7,'Paul Oakenfold')
</sql:update>
<!-- But the select screws up.... -->
<sql:query var="users" dataSource="${dataSource}" scope="session">
SELECT * FROM test WHERE 1
</sql:query>
</body>
</html>
...and the error message:
exception :
org.apache.jasper.JasperException:
SELECT * FROM test WHERE 1
: null
at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:254)
at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:295)
root cause
javax.servlet.ServletException:
SELECT * FROM test WHERE 1
: null
at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:531)
at org.apache.jsp.index_jsp._jspService(index_jsp.java:84)
...and just for completion the importent part of my web.xml:
<taglib>
<taglib-uri>/jstl-core</taglib-uri>
<taglib-location>/WEB-INF/c-1_0.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>/jstl-sql</taglib-uri>
<taglib-location>/WEB-INF/sql-1_0.tld</taglib-location>
</taglib>
i am using the jboss 3.2.3 tomcat bundle (tomcat 4.1.29)
and mysql 4.0.18 on W32 System....
the JSTL is installed and working - i can make <sql:update>Inserts without any problems, but any <sql:query>selects result in that error... so i guess the setDataSource is okay...
Any idea would be appreciated....
Thx
J�rgThose URIs you've got in your JSPs aren't correct. They should be:
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
<%@ taglib prefix="sql" uri="http://java.sun.com/jstl/sql" %>
These are the URIs defined in the standard.jar.
You'd be better off setting up a Tomcat JNDI data source for your application. That will externalize the connection parameters and make it unnecessary to refer to a data source in your JSPs.
You'd be even better off not putting SQL code in your JSPs. They're for presentation. Better to write a Java object that will communicate with the database on the JSP's behalf.
If you just want to select all the rows in the table, the query should be "SELECT * FROM test". You don't need a WHERE clause in that case.
If you change the URIs in your JSPs you should remove the <taglib> from your web.xml. It's not necessary. Tomcat will find the TLD by looking in the JARs in the CLASSPATH and matching the URIs. -
Tomcat: java.lang.NoClassDefFoundError: oracle/sql/NUMBER
hi,
i have managed to come this far with my "simple" webapplication under tomcat.
the exception is:
java.lang.NoClassDefFoundError: oracle/sql/NUMBER
since i have tried to put the classes12.jar in every reasonable directory without effect, i have to bother this forum. does anyone know "where the dog is burried"(german saying)?

Selim KeserHi yves,
This class is in the jdev_home/jdbc.lib/ojdbc14.jar.
But prior to deploying your ADF application, did you install the ADF runtime libraries to Tomact as explained here?:

Unable to make use of JSTL with Tomcat 4.1
I have downloaded jakarta taglibs 1.1.2 from Jakarta site .Copied the
Jstl.jar under lib directory which I kept under WEB-INF of my specific
web directory but tomcat is unable to identify the tag like forEach, set etc.
Same thing happened with Java Application Server.
The code is like this
Even I tried with prefix c and http://java.sun.com/jstl/core uri
<%@ taglib prefix="c_rt" uri="http://java.sun.com/jstl/core_rt" %>
<html>
<head>
<title>Simple Example</title>
</head>
<body>
<c_rt:set var="browser" value="${header['User-Agent']}"/>
<c_rt:out value="${browser}"/>
</body>
</html>
