Where to find wrapper classes
Hello,
we would like to trace an exception thrown by a wrapper class generated by the deployment of an entity bean. Where are these classes stored? Is there any possibility to keep the sources of the wrapper classes, or at least the class files to decompile them?
Regards
Stefan
Stefan -- Wrapper classes are kept in the deployment.cache file under your specific application within the application-deployments directory. You can extract the files with either jar or winzip.
Thanks -- Jeff

Servlet compilation - where to find the class files ?
Hi !
I am new to servlets and I have just downloaded Tomcat 4. I think that a servlet has to extend the HttpServlet class and throws a ServletException exception, right ? But where can I find these classes for Tomcat (I think that these don't ship with it !). I tryed to fix the problem by downloading these classes for JSDK but the Tomcat examples (which I could run) did not compile !...
It is perhaps a silly question, but could someone help me out ?
Thank youThere is a package called servlet 2.3 wich contains all the classe you need to create servlets, you can download it from

NativeSQLAccess where to find relevant classes?
Dear community,
upon trying to access a function from Java code within an EAR-project I realized that I need the NativeSQLAccess to run e.g. CallableStatements on the database as this exceeds OpenJDBCs capabilities.
I found the docs and have a good guess about how to implement it, but I can not find the JAR-file which contains com.sap.sql.NativeSQLAccess class.
Does anyone know where to find it?
thanks in advance!
regards,
ChristianHi,
You need the file "opensqlsta.jar". You can find it in the plugins folder of you developer Studio under ..\plugins\com.sap.opensql_2.0.0

I am trying to use JSP with XML for which I am writing a parser program.
But I am unable to get the following packages and classes. Kindly help me.
com.sun.xml.parser.Resolver and com.sun.xml.tree.XmlDocumentwhy do you want to use these classes? Sun doesn't recommand binding your code to com.sun.* classes, it's much better to use JAXP and realy on the platform to pick the right implementations.

Wrapper cannot find servlet class error
Hi all!
I'm receiving a mysterious error when I try to run my web ap. "Wrapper cannot find servlet class com.ruffalocody.report.ReportServlet or a class it depends on"
I'm running it on JBoss 3.2.7, and I have another web ap, made almost identical to this one which does not display the same error/exception.
If anyone could give me advice on what I should do to fix this, I'd very much appreciate it. :)

In weblogic 10.3 SafeZipFileInputStream.class is not in weblogic.jar file.
Can anyone help me where can i find this class.

Advantages,Dis-advantages,when and where -use java.lang.Void Wrapper class
Hi All,
I like to know when and where to use the wrapper class java.lang.Void and when it is particulary needed.if anyone could give me some examples it will be better.
Thanks in advance,
KathirI like to know when and where to use the wrapper class java.lang.VoidWhy? If you don't need it, you don't have to use it.
and when it is particulary needed.It is needed when you want to represent the concept of a void return value.
if anyone could give me some examples it will be better.

Failed to Generate Wrapper Class Error With Postgresql
Hello,
Sorry if this comes across twice, I posted it first through the Google Groups interface, but I haven't seen it show up on the dev2dev forum interface. So here it is again.
I've read the following threads that seem to be related to this
question:
http://groups-beta.google.com/group/weblogic.developer.interest.jdbc/browse_thread/thread/dc8f0a9ee03e9b9f/f0a70a673db3bb52
http://groups-beta.google.com/group/weblogic.developer.interest.jdbc/browse_thread/thread/4f3b71c77dca30c4/4ed2e1c7b76a0c7b
I also followed the links in the second post ( I also found them via
Google as well ). I've been very sure the Postgresql JDBC driver is
definitely in the class path. I'm able to load it with Class.forName()
from a JSP page and then use DriverManager to get a connection that
works. So that definitely means the driver is found.
What else can cause this?
The only really odd thing I am doing is running Weblogic on OS X,
10.3.7 with all the updates. I know that this Weblogic setup works
since I work on Oracle all day (using the provided Weblogic driver in
8.1SP3). Just when I try to create a Postgresql connection for testing
our app against Postgresql.
I've tried it on Windows with Weblogic 8.1SP3 and it works, so I know
Weblogic is capable of using this driver.
My exact stacktrace is:

What is going on at the place where this crashes? Is there a way find
out what class it really can't find?
Thanks,
PatrickPatrick,
1. Could you try to test the postgress connection pool using
"Test Connection" on the pool set up page?
2. Could you compare config.xml for broken and working installations
in part of the connection pool settings?

Apache comons logging implemented it with a wrapper classes around
hi friends,
i have an interesting (unsually )problem regaurding apache commons logging, i am using three classes .
one is the logger class where i instantiate the logging instance ie Log log = LogFactory .getLog("some name");
then there is a class called LFactory where i use i hashMap to store the various different logger created or to access the different logger for the hashmap
then the last i have i LoggerAccessor class which links the LFactory.
as u all now that the logger will give the line number of the class where we use the log instance ( Log log)..... but as i am using a wrapper classes around the actually log instance.
in any class where i require the logging to be done.. i used my LoggerAccessor. so instead of giving me the Actuall Classname,methodname,and line number of the class where i give logging statements. I get the name of my class where i have created the instance and specially the line number of the class where the instance is created....( means my first class).
i want to get the name,method,linenumber of the class where i have added logging statements
please find me the solution for it.....
thanksGood Question Nutan !! But i don't have answer !! Hope someone else will answer this !

CMP Entity Beans Wrapper Classes Source Code
Is there any way to have JDev or OC4J 9.0.4 save the .java source file that creates the wrapper cmr ejb classes? It would be helpful when debugging in JDev for it to have the source to debug with. Or even to just see the generated java file from the abstract cmp beans.
Any one know?
Tkx,
JimHi Jim,
If you haven't already seen it, perhaps this where to find the temperary files created during deployment (from this forum's archives) will help.
Good Luck,

What is the proper way to code a "wrapper" class?
Basically I want to replace an existing Action with a custom Action, but I want the custom Action to be able to invoke the existing Action.
The following code works fine. I can create a custom Action using the existing action and the text on the button "paste-from-clipboard" is taken from the existing Action. So everything works great as long as the existing Action extends from AbstractAction.
However the Action interface does not support the getKeys() method which I used to copy the key/value information from the existing action to the wrapped action. So if you try to create a button from some class that strictly implements the Action interface the key/value data in the wrapped Action will be empy and no text will appear on the button.
So as the solution I thought I would need to override all the methods in the wrapped Action class to invoke the methods from the originalAction object. That is why all the commented code in the class is there. But then the protected methods cause a problem as the class won't compile.
Do I just not worry about overriding those two methods? Is this a general rule when creating wrapper classes, you ignore the protected methods?
