Regarding Tomcat Server Error/Warnings

Hi there,
I am getting some errors/warnings on the Tomcat server screen...
Actually, I am using a Controller Servlet and every request is being passed thru this servlet. There are some images on the Home page (Home.jsp) but when the Home link is clicked, these images disappear....
What do these error/warnings mean?
2002-04-03 12:42:52 - Ctx( /9001 ): IllegalStateException in: R( /9001 + /Home.jsp + null) Cannot forward as OutputStream or Writer has already been obtained
2002-04-03 12:42:52 - Ctx( /9001 ): 404 R( /9001 + /servlet/getacro.gif + null)null
2002-04-03 12:42:52 - Ctx( /9001 ): 404 R( /9001 + /servlet/getie.gif + null) null
2002-04-03 12:43:04 - Ctx( /9001 ): IllegalStateException in: R( /9001 + /Contact.jsp + null) Cannot forward as OutputStream or Writer has already been obtained
Any help would be much appreciated
Thanks!!!

I believe this means that the JSP has already committed to sending data to the output stream, so it can no longer do a redirect or forward. If you have redirect or forward logic in your page, you should execute it before you write any data to the output stream. This means it needs to be the first thing in the page before any html is written.

Regarding Tomcate server exception

Hi,
I am working on tomcat5.5 v.I want to deploy one application on it.Which is fetching port no from its server.xml file like--8080 or 8083...when i am going to deploy it on it.It giving me a exception on its log like...below...
INFO: The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: C:\Program Files\Java\jdk1.5.0_04\bin;.;C:\WINNT\system32;C:\WINNT;C:\WINNT\system32;C:\WINNT;C:\WINNT\System32\Wbem;C:\Program Files\Microsoft SQL Server\90\Tools\binn\;C:\Program Files\Java\jdk1.5.0_04\bin;
please help me what should i do for this....urgent

i can suggest you to do onething.. which even i am not sure. There is a variable called PATH or CLASSPATH. You need to add another value which contains the path for the tomcat library.
Right click my computer to go to properties and click on variables tab.
there are two variables system variables and user variables. If u have admin rights go for system variables . otherwise use uservariables. edit CLASSPATH variables.. by editing i mean that u need to do the following
Add the path ( path to Apache Tomcat Native library )to the value.

Whenever I start the tomcat server, Im getting an error in netbeans?

Whenever I start the tomcat server, Im getting an error in netbeans?
Starting of Tomcat failed. '127.0.0.1' is not recognized as an internal or external command, operable program or batch file.
Even I set the path & catalina_home in Environment variables. I start the startup.bat file and catalina.bat file also.
I'm waiting for your quick response.

Hi Ershad,
I think this issue is more related to Apache Tomacat, I would suggest you ask in Apache Tomcat forum for a better support, it is appropriate and more experts will assist you.

The above error message i am getting in Tomcat server,i am having Oracle 11g V1..My SQL prompt is open and i have a table named "ourusers"...Can anyone kindly gimme the solution for this problem+*
Edited by: sandy on Nov 9, 2010 8:59 AM

java.sql.SQLException: ORA-00904: "SANDY": invalid identifier
Looks like the sql you are submitting is invalid.
Print out a copy of the sql you are trying to run and you will probably get:
SELECT * FROM OURUSERS WHERE usr = Sandy and password = secretThat isn't valid sql. It is missing quotes around the values you are checking.
This is the corrected sql query:
SELECT * FROM OURUSERS WHERE usr = 'Sandy' and password = 'secret'so one solution would be:
String sql = "SELECT * FROM OURUSERS WHERE usr = '" + user + "' and password = '" + pwd + "' ";However that is not optimal. It exposes your code to sql injection attack.
The better way is to use a prepared statement:
String sql = "SELECT * FROM OURUSERS WHERE usr = ? and password =?";
st = con.prepareStatement(sql);
st.setString(1, user);
st.setString(2, password);
rs = st.executeQuery();cheers,

I have put the castor-1.3.1.jar file in plugin folder .Then also same error.I can see the BindXmlDescripto.class file in the jar.
what could be the reason.

You need to put any associated jar files in the WEB-INF/lib directory. That should fix your problem.
The Developers Guide section on "Create a Plugin" describes what goes in the WEB-INF/classes/plugins and what goes in WEB-INF/lib

Hi,
ClassFormatError is Thrown when the Java Virtual Machine attempts to read a class file and determines that the file is malformed or otherwise cannot be interpreted as a class file.
So check whether you have properly configured servlet and whether class file is VALID and is in right place or not.

Error in re-creating RMI registry when reloading Tomcat server.

Hi,
I use LocateRegistry.createRegistry() in a servlet which is load-on-startup. I've unexport the registered remote object in the HttpServlet.destroy().
But when I reload the tomcat server, such an exception ocurrs:

                try {
                    LocateRegistry.createRegistry(ru.getPort());
                    Naming.rebind(url, rmiImpl);

                    e.printStackTrace();// handle exception
        }Can anybody help?
Thanks.

Hi
I havent code for quite a while.
I would think that this wont work.
The registry is created on startup (possibly init method in ur servlet) but it is never destroyed.
You are better off starting the registry externally to ur servlet engine, and then use do a bind/rebind on startup, unbind on destroy.
Hope this helps.

Tomcat 4.0.4 Internal Server Error with JWSDP 1.0.01 examples

Tomcat server 6.0 with jdk1.6 Path error

Hi,
my tomcat server is through the error while i compaily servlet files. already path was setted. the path but also it through the error pls.... some body help me to solve this error.
Path are:
CATALINA_BASE=c:\Program Files\Apache Software Foundation\Tomcat 6.0
CLASSPATH=.;C:\Program Files\Apache Software Foundation\Tomcat 6.0\bin\bootstrap.jar;d:\jdk1.6\lib\tools.jar;c:\Program Files\Apache Software Foundation\Tomcat 6.0\lib;c:\jdk1.6\lib\tools.jar;%JAVA_HOME%\lib;%JAVA_HOME%\lib\tools.jar;%TOMCAT_HOME%\lib
JAVA_HOME=d:\jdk1.6
JRE_HOME=c:\j2sdk1.6
TOMCAT_HOME=c:\Program Files\Apache Software Foundation\Tomcat 6.0
Path=%Path%JAVA_HOME%\bin;;d:\jdk1.6\bin.

Sorry but your question isn't related to Java. It's a pure Tomcat question and should be asked in a Tomcat forum. (And they probably wants to know how it fails, and what error messages you get)

You could at least have posted the exception.

CF10 500 internal server errors

I have recently installed CF10 on a Win 2008 R2 server it will open the main pages (index.cfm) but if I try to browse to the links within the site I get a 500 internal server error or 404 file not found. I have looked at a few articles in regards to creating a virtual directory named jakarta this works for only one site and seems to only work if I set that virtual directoyr to the wsconfig\1 folder. I am not familiar with CF by anymeans so if answers could be as rookie as possible.
Thanks,

Thank you for your kind words A little bit which I've learned in CF in only because of all our CF users who post their queries/answers and indeed you are one of them
Usually when you set Enable 32-bit Application pool to false, you need not to restart IIS however during maintenance window you can restart IIS
Another thing which I want to confirm, have you added an application/applications under a website and assigned those to separate application pools?
If yes, then please change the application's pool to the website's pool. So if, default website has 4 applications under it, then all four applications must be assigned with Default App pool (The app pool for default website).
For testing purpose, Add a new webiste in IIS. Place a test.cfm and test.html in the web root of this website. As you mentioned that you have configured connector with All, then you need not to run the web server configuration tool. Add CFIDE and jakarta as virtual directories in this new website. Also, make sure that the ISAPI filter has a tomcat entry for this website as shown in the screenshot below. It should be there because you have configured with All so the tomcat entry should be at the server level and this new website will inherit the property from server.
You can also enable the detailed error for this test website and share the error which browser will return if you encounter the same issue Share the results for .cfm and .html returned by the browser.

Thanks
