Debugging classes under web-inf

Hi,
          I have been working with JBuilder 4.0 and wl 5.1\6.0 for some time now and
          was able to debug all of my code while it was in the weblogic classpath (or
          any other top level class loader).
          I have recently moved all of my web-based classes to the web-inf\classes
          directory, where they should be ... (I did that so a simple deploy\undeply
          of my web-application is all I need when I have fixes to my web-based source
          code, and of course to follow the spec).
          What happened is that now when I attach to the WL using the JBuilder, the
          JBuilder doesn't recognize any of the classes in the web-inf\classes. If you
          know JBuilder then it sets the breakpoint as if it never reaches the code
          (even if I ran it once before attaching).
          From this behavior I understand that JBuilder knows only the classes in the
          weblogic\jvm classpath.
          First I would like to know if this behavior is correct, or I'm simply doing
          something worng (which is quite likely).
          And second I'd like to know what can I do so I'll be able to debug them as
          they are (and please don't tell me to put the classes back where they were,
          up in the class loaders hierarchy, I gathered that much by myself).
          Thanks,
          Asher.

Hi,
i have the same Problem and i can't a solution anywhere.
I have one ejb-jar successfully deployed on WLS 6.1 and copied alle ejb-interfaces into /WEB-INF/classes of the web application (no ear or war-files are used).
For jsp-compiling these classes are found and used but at runtime the jsp's cannot find the interfaces and throw NoClassDefFoundErrors.
I also tried to use the ClassPathServlet (described in http://e-docs.bea.com/wls/docs61/webapp/components.html#139205 ), but the classes are not found too.
Please help. I thing it is inadequate to put the ejb-interfaces into the server's classpath too.
Thanks
Ray

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

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:

Warning - When Compiling .jsp pages under WEB-INF

Created a directory jsp under WEB-INF and when i compile the jsp pages i get the following warning message
Warning: package name web2d_inf._jsp does not match source file name C:\ProviderEnrollment\ProvEnrollView\classes\.jsps\_WEB_2d_INF\_jsp\_searchprovider.java
Need help
Thanks

We have encountered this warning too.
I'm not an Oracle employee, but it looks like there's a bug in JDev that preserves the case for the output directories but not for the package name that is supposed to correspond to the output directories.
In any case, we haven't seen any runtime problems that seem to be related to this warning, so you may be safe to disregard it. It does foul up the build log though.
Any JDev team members watching this topic are welcome to chime in with a confirmation and details of this apparent bug, as well as any workaround that might exist to avoid having the warning appear. Thanks!

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>

          </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

JAR files under WEB-INF but not in lib directory

I am working with JDeveloper 10g and I have several jar files under WEB-INF/lib and other under WEB-INF/libEst.
I have add this libraries to Project properties > Paths and it works fine when I run my aplication in local environment, but it fails when I deploy and run in the server.
I have configured our deploy file to include these WEB-INF/libEst jar files, but when I deploy to our server, it seems to be that this classes included in these jar files are not reachable and they cannot be loaded and throw a ClassNotFoundException.
Is it possible to have jar files under any WEB-INF subdirectory distinct of /lib?
Why is it working in local but not in server?
If someone can help me to configure this in order to deploy in server, I will be very grateful.
Thanks a lot,
Antonio.

Hi Antonio,
I think this document is what you are looking for: http://www.oracle.com/technology/tech/java/oc4j/htdocs/how-to-servlet-warmanifest.html
.. your manifest entries would look like
Class-Path: WEB-INF/libExt/<jarName1>.jar, WEB-INF/libExt/<jarName2>.jar, ...
Let me know if this works for you.
thanks,
Harsha

Does JSP best practice of putting under WEB-INF apply to JSF pages?

I'm new to JSF and wondering if the "best practice" advice that used to be given of storing your jsp pages under WEB-INF (when using Model2) to keep them from being served up without going through your controller still applies with JSF.
Since the component lifecycle is so different, I'm wondering if it would still apply? If anyone can explain why it might or might not apply I'd appreciate it!
Thanks!

The rule is:
keep all the pages you don�t user to "browse", under the WEB-INF directory.

Access JSP pages under WEB-INF

Hello, I have a web application and i use Java,JSP, servlets etc.
In my webpage i have three different categories of users
*1)* Registered users
*2)* Not Registered users
*3)* Administrator
I would like the welcome page index.jsp and register page be accessed by everyone.
But as far as the other pages are concerned , i would like to be accessed only by the registered users.
What shall i do??
I placed the index.jsp and register.jsp under the public folder and the other pages under WEB-INF folder in order to be accesses only from the registered users.
But it's not working!
What exactly shall i do in order to make that work??
Thanks, in advance!

Registered , Not Registered and admin.
Yes, security constraining through web.xml is a url pattern based protection for your resources. You could create multiple urls - /secured/* and map them to your resources accessible to registered users only or you may have /admin/* and define that only 'admin' roles have access to these resources. Some portions of such setup would be server specific (eg: how you create users and map them to roles)
*2)* I would like to make a question: Who is the "FrontController" in the link you posted me? [http://onjava.com/onjava/2001/08/06/webform.html]
It's the Container. Because such features are mandated by the spec, the container provides an implementation and options to customize the implementation (for example in weblogic, you can specify that your users are bound to an LDAP or configured in a Users table in the db)
Nevertheless, you would have your own Controllers for your application management (Struts or Spring or whatever suits your need). On the same note, you should have your own Filters to implement whatever common logic you have across your application.

*3)* when you write "_entitlements_" what exactly do you mean??
Thanks!
This is the other road I was talking about. You could throw all configuration and j2ee based security configuration out of the window (they do have their limitations) and implement custom security logic in a Filter. For example,
String urlPattern = request.getRequestURI();
if(urlPattern.indexOf("/secured") != null{
         if(request.getSession(false) == null){
               //redirect to login page.
         }else{
              //valid session
              //now check specific entitlement to see whether user has access
}Here entitlement refers to permissions at a granular level (authorization if you wish to call it). For example, you have 2 kinds of admin users - some who can generate reports of web activity and another who can change application settings.

Pros and Cons of putting jspx pages under WEB-INF

Greetings All,
I have been using JHeadstart release 10.1.3 Prod for a while now and was generating pages in various subdirectories under WEB-INF/pages/ and things are working fine.
However, recently I came across a post in jDeveloper forum Re: Access JSF Pages within WEB-INF directory where Frank Nimphius has mentioned that there is no sense in putting JSP files that are used with JSF into WEB-INF.
I know that in struts world it makes sense to put the jsp files under WEB-INF to prevent the users from directly accessing them and force them to access them only via struts actions/navigation rules; but in JSF world we anyway expose the jspx names to the user and in-fact if we keep the pages under WEB-INF the url to access the pages also contains 'faces/WEB-INF/...'
Thus, I would like to get opinion from various experienced professionals participating in this forum and more so from JHeadStart team members on Pros and Cons of putting jspx pages under WEB-INF
regards - rutwik

Rutwik,
From your reply it seems that, for now, there should not be any impact on us as long as we don't upgrade to JDeveloper 10.1.3.1, as anyway the current JHS version is not certified against it.
Correct.
However, to be compatible with future releases of JHS and JDeveloper, will it be good to change the location of pages in our JHeadStart definitions to move them a directories above the WEB-INF etc and re-run the JHeadStart generators?
Yes.
Or, will the patch take care of modifying the current JHeadStart definations?
No, Service Update 1 has a different default value for the pages dir , it is now /pages/ instead of /WEB-INF/page/, that's all.
Also, with this patch, will we be able to upgrade to jDeveloper 10.1.3.1, which we would like to do once we have a production release?
Yes, Service Update 1 is compatible with JDev 10.1.3.1

[weblogic 8.1-sp4] taglibs not allowed any other place then under WEB-INF?

i pack my application as EAR with several skinny WARs + JAR libs under "lib" directory of EAR (and ofc WARs have their manifest adjusted to point to those). standard.jar is also there, no web.xml definition of the taglibs.
when i deploy the EAR, any of the JSPs throw famous IOException: "cannot resolve 'http://java.sun.com/jstl/core' into a valid tag library".
i dug a bit and saw people mention that TLDs are scanned for only when they are placed under WEB-INF of a WAR (hence you suck when your TLDs are somewhere else like "/lib" in my case) and classpath has nothing to do with that. is it true and what can be done to avoid it?
ps.
to clarify: servlets 2.3; jstl 1.0; jsp 1.2
Edited by: [email protected] on Dec 8, 2008 6:33 PM

well placing 10 taglib definitions in each web.xml is imho a bad idea. as there's no real way to exclude all but certain JARs from a WAR using maven (the ideal solution i'd prefer), the solution i had to choose was to set maven-dependency-plugin up the way it would extract the TLDs from certain JARs and place it anywhere under WEB-INF of the WAR when it's assembled. the cons is that TLDs are duplicated, but on the other hand the configuration for that is minimal (which also seems important to me).

DefaultServlet bug? forwarding to static content under WEB-INF

I've encountered what seems to be a bug in the DefaultServlet in WebServer 7.0u2, when trying to do a requestDispatch->forward to static content (e.g., a .png file) under WEB-INF. In general, I can forward into content under WEB-INF, and my servlet works fine when forwarding to dynamic content under WEB-INF (e.g., a .jsp file), but when I try to forward to static content, a 404 error is sent. The same servlet also works fine if I put the static content outside of WEB-INF. In summary:
forwarding to /WEB-INF/foo.png responds with error 404 (even though the content exists)
forwarding to /WEB-INF/foo.jsp works fine
forwarding to /other-dir/foo.png works fine
I'm baffled as to why I can't forward to static content under WEB-INF. I have a very simple web.xml file, and no suffix-based mappings, so the only servlet that should be responding to the forward is the servlet container's DefaultServlet. Is there some bug in DefaultServlet? Am I misunderstanding something?

pl. upgrade to latest update (web server 7 u5 as of now) and see if your problem is still reproduced.

Custom classes in Web-INF/classes not recognised

          Can any body tell me why classes in WEB-INF/classes directory are not recognised by
          the WebLogic while importing in JSP??
          Thanks in advance


          Hi all,
          we were having the same problem - WebLogic not recognizing custome classes in
          the WEB-INF/classes directory. As soon as we removed the Class-Path entries from
          the WARs Manifest file (and placed the referenced JARs in the WEB-INF/lib directory)
          everything worked fine. It seems as if WebLogic excludes WEB-INF/classes from
          the classpath in case Class-Path entries in the manifest file are present.
          Is there a patch for this? If yes, I'd appreciate your notice!
          Cheers
          Georg

Isp file under WEB-INF call css file and jasript file

Hi , is that OK to call a jascript file or css file if the jsp file is under WEB-INF? How to do that?

You have to remember that all client side requests will be of 2 types: relative or absolute. If you refer to the file using the absolute URL of the resource (like http://www.my.com/application/resources/content.css) then you will have no problem.
If you use a relative URL, the URL has to be relative to the address that the client sees on the browser. The JSP may be in the WEB-INF directory, but the client doesn't see that. They put in a URL like http://www.my.com/application/process and the server included/forwarded to the WEB-INF content which the client doesn't see or know about. So when you use a relative URL, the URL has to be relative to http://www.my.com/application/process and not to http://www.my.com/application/WEB-INF/<...>/display.jsp where the JSP actually lives.

Faces under WEB-INF

Would I run into any problems if I chose to place jsf enabled jsp's under the WEB-INF folder to take advantage of the fact the files here cannot be directly accessed?
I am thinking the faces servlet would be able to access them but I don't have much experience with JSF and don't want to take off in the wrong direction.
Any thoughts?

David,
You'd likely be better to ask on the WTP newsgroup. I don't really
understand the problem you are describing but I suspect that if it's not
showing the content under that folder, it's showing the content
elsewhere in the view of that same project. Certainly if you use
"File->Show View->Navigator" it will show you more of a raw view of
what's actually there...
