WEB-INF/lib class reloading

Are the jar/zip files placed in the WEB-INF/lib directory
of the web app reloadable i.e. if the classes in the jar file
are changed would they be reloaded by the webapp
class loader just like the classes in the WEB-INF/classes
directory?

1ro que nada te aconsejo que respondas en ingles... este es un foro en esa lengua.
si tu ingles es malo te sugiero que uses http://babelfish.altavista.com
2) do you have include the Reports library in yours projects.

JAR Files not found from /WEB-INF/lib

It appears that weblogic server (6.1 SP2 I believe) is not finding all
the jar files in the /WEB-INF/lib directory. Some, but not all. I am
not using a WAR file, the dirctories are right on the disk. I start
out with the following jar files in my WEB-INF/lib directory:
Volume in drive C has no label.

Can you please suggest a solution to this problem?

Hi,
the binding file is not supposed to be located in this directory. So check your project structure. How did you get to this exception?

Tomcat6 does not load class files from WEB-INF/lib/myjarfile.jar WHY???

I have placed my jar file in c:\tomcat6\webapps\my-application\WEB-INF\lib\myjarfile.jar
But, after restarting tomcat6, when i try to import the class file contained in the myjarfile.jar in a servlet, it says
ProcessFileUpload.java:4: package test.test1 does not exist
import test.test1.*;
^It clearly tomcat's class loading problem.
As i unzipped my jar and placed the packagefolder structure to
c:\tomcat6\webapps\my-application\WEB-INF\classes\testand it works perfectly.
Anyone knows its workaround? please suggest if any configuration changes is required in tomcat or so.
Thanks.
---Sujoy

Thank you gimbal2 . There was error in creating the jar file myjarfile.jar.
But, now I have created it again and placed it in place
c:\tomcat6\webapps\my-application\WEB-INF\lib\myjarfile.jarand tried to use one on the Class file included within the jar to compile my servlet. But, still I am getting error at servlet compilation time. I want to place executable jar files in
c:\tomcat6\webapps\my-application\WEB-INF\lib\myjarfile.jar and compile my servlet and execute the servlet.
I DO NOT WANT TO unzip the jar, placing all unzipped files to
c:\tomcat6\webapps\my-application\WEB-INF\classes\ folder and comiple my servlet and execute the servlet. But, I am failing to user WEB-INF\lib\ folder facility....please help me why i am not getting class files from WEB-INF\lib\ folder.
If you please see the small code bit and tell me any possible error that would be very helpful.
Step 1: my library java file MyClass.java
package test.test1;
public class MyClass {
     String myName = "Default return string value";
     public void setMyName(String varName) {
          this.myName = varName;
     public String getMyName() {

Wl6.1sp2 can't find classes in WEB-INF/lib

          Hi,
          I meet a very strange problem.
          I use struts in my application.so I put struts.jar in web-inf/lib.
          In the .war file, the struts.jar can be found under web-inf/lib.
          my servlet configuration in web.xml is:
          <servlet>
          <servlet-name>action</servlet-name>
          <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
          <init-param>
          <param-name>application</param-name>
          <param-value>StrutsProperties</param-value>

          </init-param>
          <load-on-startup>1</load-on-startup>
          </servlet>
          when this .war file is deploy, the console not show any error message.
          then,when i visit a jsp page that has a <html:form> tag, the console will show
          the error below:

Please help.! Problem with locating classes within Jars under WEB-INF/lib.

Hi All,
I have a problem which you guys would have faced already...Here it goes..
I'm using OC4J 10.1.3.0 and use ADF for my web page. I have a controller class which refers to JSF/ADF APIs and this class is archived as a jar file and put under WEB-INF/lib, Also, all the classes related to JSF/ADF are available under the same WEB-INF/lib folder.
When I invoke my page, the controller class is getting called but it throws NoClassDefFound Error for the ADF based class. i mean, these ADF/JSF classes are not getting found when my jar class is placed within WEB-INF/lib. However, when i extract my jar into WEB-INF/classes, it works.
I'm sure, i miss some entry for classpath somewhere. Can any one please point me to right direction...?
Thanks
Rajasekaran

Hello,
I do not have a direct answer to your question, but could you try the ClassLoader query tools to see if your classes/jar are loaded by the applications:

Is there a restriction on loading "javax" classes from WEB-INF/lib?

I'm having trouble with a webapp in WL 10MP1 that is having trouble loading classes from the "jsr311-api-1.0.jar" in my WEB-INF/lib. Even though I have no trouble with it in Eclipse (no compile errors), classes from that jar fail with "NoClassDefFound" exceptions. I have a feeling it might be the fact that the packages in that jar start with "javax". Assuming that's the case, is there anything I can do to fix this?
What's even stranger is that the errors I get are when I try to load them directly from the Spring context. However, if I remove the test references to those classes, there's other code that loads those classes later in the application startup (after the Spring context finishes loading), and they load perfectly fine (I turned on verbose class loading to verify this).

Note that I've tried two other strategies that both result in the same failed state.
I tried putting the "jsr311-api-1.0.jar" in $JDK_HOME/jre/lib/ext, but that causes a failure to find Spring classes. I then copied the "spring.jar" into $DOMAIN_HOME/lib, and then it fails to find CXF classes. After doing the same with "cxf-2.2.3.jar", it then fails to find "javax.servlet.ServletContextListener", which clearly tells me there's no benefit to this approach.
Similarly, I tried copying the jars into $DOMAIN_HOME/lib, and that fails to find "org.apache.commons.logging.LogFactory". I could continue down this path, but it doesn't seem likely to succeed. Eventually, I'll get to a point where it just can't find the classes specific to my application, which I certainly can't copy into $DOMAIN_HOME/lib.
The first basic problem is that I can't put anything into a higher-level classloader that will eventually reference classes in a lower-level classloader, because references can only go up the chain, and the second problem is that WebLogic appears to ignore classes in WEB-INF/lib in the "javax.*" packages. I think there might be an exception for "javax.xml.*", but not for other subpackages. I tried adding a "prefer-application-packages" clause to my weblogic-application.xml file, but that had no effect.

WEB-INF/lib WEB-INF/classes ClassLoader problem

I have observed that in WL 8.1, a class in a jar deployed in WEB-INF/lib does not have the ability to access a resource deployed in WEB-INF/classes. Is this the intended behavior to not have WEB-INF/lib and WEB-INF/classes in the same ClassLoader? If so, is there a way to configure this behavior to give permission to classes loaded in WEB-INF/lib to the ClassLoader that has WEB-INF/classes?
thanks,
Kenneth Shin

Are you really certain that's what's happening? Is it possible the jar file stored in WEB-INF/lib isn't found elsewhere in the CLASSPATH, perhaps by a higher-level classloader? You might consider setting "prefer-web-inf-classes" to true in your weblogic.xml file, to ensure that the jars in WEB-INF/lib are being used instead of from somewhere else.

Classes in web-inf/lib not being found.

I'm having problems with a servlet app in which jar files placed in the web-inf/lib of the application are not found at runtime.
If I put them in J2ee\home\lib they are found OK.
This application has previously deployed and worked correctly, then I added another servlet and redeployed, and classes that were previously found OK stopped being found.
On checking the server all the directories look correct.
What could be causing this and how can I make my web applications deploy reliably?
OC4J version is 9.0.3.0.0.
Thanks

Guys,
Have you tried with the production version of OC4J 9.0.2 ? It should work. Please download the production version of OC4J 9.0.2 and give a try.

About web-inf\lib

I copy all jar files from %ProgramFiles%\Common Files\Crystal Decisions\2.0\
jars and put in the "WEB-INF\lib" directory of my web application but WSAD s
till don'know Crystal Report Classes.What should I do to fix this problem?

After copying it need restart the web server if you don't use some tool to reload your application. If it still doesn't work, you must check if it has some conflict in shared/lib and common/lib and read the log file

MySql driver not found in WEB-INF/lib

     ... 60 moreI don't really understand how I can setup the CLASSPATH in this
context. So there should be something else. Does anyone have an
idea?
Thanks.
Igor

This is what I achived using the <metainf> tags from
war task in build.xml. Look at the first code
listing. The
magic code is:
<metainf dir="${meta.dir}">
<include name="context.xml"/>
</metainf>where ${meta.dir} is defined as ./meta and there
resides
the context.xml file (look at the project layout).Very good, thanks.
Any guesses why Tomcat is not loading mysql jar from
WEB-INF/lib directory?No. 8(
My understanding is that JARs in the WEB-INF/lib are visible only to your web app. Those in /common/lib are visible to all apps and the container. Those in /server/lib are visible only to the container and no apps. It SHOULD work from WEB-INF/lib. I've done it that way, but it was an older version of Tomcat.
Checked the Tomcat docs. They say to put it in /common/lib, but they don't explicitly forbid it in WEB-INF/lib.
I'll try a simpler example.

Oc4j 10.1.3.0.0Prev4 does not load libs in WEB-INF/lib

Hi,
trying to use an existing application with oc4j I have serious problems.
When trying to deploy I get exceptions (ClassNotFound) of classes that are in libs that are in the WEB-INF/lib folder of the war file I want to deploy:
05/09/23 17:20:21 CharScanner; panic: ClassNotFoundException: org.hibernate.hql.ast.HqlToken
This class is in hibernate3.jar which is included in the war-file.
When I place all the libs into the applib folder it does deploy. But then it crashes at runtime telling me the classes are duplicate (one in the war, one in applib).
Any suggestions what I can do would be greatly appreciated.
Norbert

Hello,
Instead of simply dropping the Jar file in the applib directory you should create shared libraries that will give you better control of what is happening at the classloader level (System, Application and Web Application)
Please take a look to the 10.1.3 How tos about shared library. (Swapping XML parser and JDBC driver), and also to the documentation, chapter 7 "Using Shared Libraries" of the OC4J Configuration and Administration Guide

How to setup using WEB-INF/lib in weblogic 10.3.1

Hello everybody:
I check weblogic 10.3.1 in %WLS_PAHT%/modules find com.bea.core.apache.commons.lang_2.1.0.jar.
But I want using org.apache.commons.lang.time.DateUtils.addDays(java.util.Date date, int amount).
In server version,no this method
So I download commons-lang 2.4 from apache,and put it in WEB-INF/lib.
and I aslo setting this :
<?xml version="1.0" encoding="UTF-8"?>
<wls:weblogic-application xmlns:wls="http://xmlns.oracle.com/weblogic/weblogic-application" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/javaee_5.xsd http://xmlns.oracle.com/weblogic/weblogic-application http://xmlns.oracle.com/weblogic/weblogic-application/1.0/weblogic-application.xsd">

<wls:application-param>
<wls:param-name>webapp.encoding.default</wls:param-name>
<wls:param-value>UTF-8</wls:param-value>
</wls:application-param>
<wls:prefer-application-packages>
<wls:package-name>org.apache.commons.lang.time.*</wls:package-name>
</wls:prefer-application-packages>
</wls:weblogic-application>
but when I run
<body>
<%=DateFormatUtils.format(DateUtils.addDays(new Date(),2),"yyyyMMdd HHmm")%>
</body>
this result :
The method addDays(Date, int) is undefined for the type DateUtils
<%=DateFormatUtils.format(DateUtils.addDays(new Date(),2),"yyyyMMdd HHmm")%>

How to load .jar files of subfolder in web-inf/lib folder?

Hi All,
In 'webapps\myappliction\WEB-INF\lib\myfolder' and in myfolder have some .jar files. How to load subfolder jar files in weblogic server 10.0?
Do I need to configure subfolder jar path in web.xml? Please help me.
Thanks & Regards,
Gangadhar

Class loaders associated with a Web application can be configured to locate local classes first. To enable this we have to set the <prefer-web-inf-classes> to true in the deployment override weblogic.xml, for example
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
