IllegalStateException: strict servlet API:

Hello All,
I'm trying to do a simple rpc webservice. The wsgen process runs to a successful
completion and I deploy the result to Weblogic 6.1 sp1, which is also successful.
When accessing this new service, everything runs fine until the response is generated
and I get following stack trace:
 
java.lang.IllegalStateException: strict servlet API: cannot call getWriter() after
getOutputStream() 
at weblogic.servlet.internal.ServletResponseImpl.getWriter(ServletResponseImpl.java:160)
 
at weblogic.soap.server.servlet.StatelessBeanAdapter.reportFault(StatelessBeanAdapter.java:238)
 
etc...
It would appear that this is being generated in a Weblogic class. There is no
mention of my EJB in the stack trace.
Has anyone seen this error? Or, better yet, what causes it and what is the solution?
Thanks,
Kris

Kris,
I too have run into this problem with Weblogic 6.1. The first time I
got this exception was when I had java.util.Date attributes within my
serializable data object that I was returning from my WebService interface.
When those date attributes were set with values, I would get the exception
outlined below. Then I set those date values to null, and everything worked
fine.
Coincidentally, I'm currently have the same problem with a serializable
object that has another serializable object defined as an attribute. I'm
not wondering if Weblogic can't handle Serializable objects within other
Serializable objects?
I guess my suggestion would be to look at the values you are returning
and passing in as parameters to your WebService interface, are there any
Serializable objects that have other Serializable objects defined as
attributes ( Strings don't count )? If so, set them to null and try your
WebService again. ( Does that make sense?? )
Hope this helps?

IllegalStateException: strict servlet API: cannot call getWriter()

I am getting an exception in Weblogic when I am trying to display a pdf file in a web page.
java.lang.IllegalStateException: strict servlet API: cannot call getWriter() after getOutputStream()
I am using the following code code
ByteArrayOutputStream baos;
ServletOutputStream out = response.getOutputStream();
baos.writeTo(out);
I have seen this error in so many discussion forum and there is no proper solution for this error.
I am able to see the pdf page even with this exception. But I want to get rid of this exception also from Weblogic.

I just did a quick (and dirty!) test with the following to display a jpg image and it worked for me without any trace of an exception:
    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        response.setContentType("image/jpg");
        File f = new File("/Users/me/Desktop/IMG_0032.JPG");
        byte[] bits = new byte[(int) f.length()];
        FileInputStream fos = new FileInputStream(f);
        fos.read(bits);
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        baos.write(bits, 0, bits.length);
        baos.writeTo(response.getOutputStream());
        baos.close();
        fos.close();
    }Note that there is no call anywhere to response.getWriter() in that.
I'd guess the exception is directing you at what the problem is, at least as the server is seeing it -- somewhere in the execution of the request path there would appear to be call to response.getWriter() occurring after a call to response.getOutputStream() has been called, which is not permitted on WLS according to the error message.
Do you use filters on this app? If response.getWriter() has been called on the same response object in a post request filter phase, that would be on the same call path with the same response object and would result in the exception.

any idea? thanks!!

finally {

catch (IOException e) {

throw new ServletException();
}

thanks for you reply. but seems we don't call getWriter() at all in our code.
actually this error only happen in our customer's env, no this issue in our development env.
besides using getOutputStream() and getWriter() simultaneously for same response, is this maybe related with some web server configuration?

Strict servlet API: cannot call getWriter() after getOutputStream()

Hi,
Am getting below exception when i click on create report button.
It was successfully running in development machine, when we deploy the same application into the testing server.
what could be problem..

I need to install servlet-api.jar in the libext folder.

Hi I am doing a tutorial on struts 2.0.11.
i need to install servlet-api.jar in the libext folder which I have created inside WEB-INF
Now I have downloaded servlet.api which is in the zip form.
When I extract the files. Its giving me two folders
1. javax
2. META-INF
Inside javax there is a folder called servlet. Inside servlet folder there are
a) bunch of call files
b) http folder
c) resources folder
Inside http folder there are
a) class files
b) properties files
Inside the resources folder there are
a) dtd files
b) xsd files
Inside the META-INF folder there is the manifest.mf file
I just need servlet-api.jar
I think that I have extracted the contents of servlet-api.jar by using the extract feature of winzip.
Do you think that by just changing the extension of the file from servlet-api.zip to servlet-api.jar it will do the trick or do i need to do something else.
Please guide

Hi ^^,
your replies were very helpful. I did try to check the lib folder of the webserver and there was not servlet-api.jar. However I downloaded a dummy project and it did have servlet-api.jar in it, so I am ok for now.
thanks and regards,
PrashantYou should not be doing that. Always use the one from the application server which you're going to use. Otherwise you will possibly get in runtime trouble due to version differences.
The actual location and filename of the servlet API might differ per application server implementation. If it was for example Tomcat 6, it is the servlet-api.jar in the /lib directory. If it was for example Glassfish (the current release), then it is the javaee.jar in the /lib directory.

How to insert the new Servlet Api Class files?

Hi,
I need to know how do I add the Servlet Api Class to my java directory
after i download it from the net? Thanks for your help in advance!

niceguyme,
If you downloaded the J2EE 1.3.1 API and installed it to (for example) c:\j2ee131, then what you need to add to your class path is:
c:\j2ee131\lib\j2ee.jar
I also add c:\j2ee131\lib\ejb10deployment.jar to the classpath, but it is not necessary.
there are several ways to add these to your classpath. It depends on what Operating System you are using. On windows 98 type OS, you can edit the autoexec.bat and add these directly to your already existing classpath. Windows NT,2000, and XP: you can add them to the system environment variables classpath. Hopefully you know how to do this on your machine. What I like to do on the windows machine is create a batch file that will start it from within a command prompt. I do this because there are times when I need to compile my code using different versions of the Java api. I am enclosing an example of one for J2se1.4.1 and j2ee1.3.1.
contents of java141.bat
@ECHO OFF
ECHO JDK 1.4.1 and J2EE 1.3.1 are current versions

Setting session timeout in servlet API 2.0 - based JSP (Apache/JServ)

I'm using Apache/JServ (servlet API 2.0) to run JSPs. At present, a session becomes invalid after 30 minutes of inactivity. How can I increase or decrease this time?
Thanks.

You can set by using this command in JSP or servlet
session.setMaxInactiveInterval(1800);
replace 1800 (this is in seconds) with the number you want

Servlet API 2.4

I would like to download a copy of Servlet API 2.4 class files. I know that Servlet API 2.4 is part of the J2EE 1.4 download, but I really don't want (or need) the entire J2EE. So far, all I've been able to do is download the specification.
There is a link to download Servlet API 2.3 class files, which I am currently using with NetBeans 4.1. I would like to add v2.4 to my NetBeans library.
Does a link exist to download the Servlet API 2.4 class files and dox? If so, where can I find it? Any help would be appreciated.

Hi Martin,
Ivo is right. Web AS 6.40 is J2EE 1.3 compliant and implements Servlet 2.3 specification. In Servlet 2.3 API its not explicitly said that the contextInitialized() method in ServletContextListener interface should be called before any servlet or filter is initialized. In this release the ServletContextListeners are notified of context initialization after servlet and filter initialization and thus informing them that web application is ready to process requests.
Unfortunately there is no workaround as it is implementation dependent, and of course of reasons for backwards compatibility such changes could not be done.
What concerns your second question is that the J2EE 1.4 (hence, servlet 2.4 API) support is planned for the next release of the Web AS. In that release the contextInitialized event will be thrown before any servlet or filter is initialized.

Diyan

Servlet API

I believe the servlet APIs are outdated in the Oracle 9i AS Portal 3.0.7 distribution, i.e. Servlet 2.0 API. Can anyone confirm or deny this? An application that runs on a 2.1 Servlet API bombs on 9i with the following error:
[18/01/2001 13:47:11:490 CST] java.lang.NoSuchMethodError: javax.servlet.ServletContext: method getRequestDispatcher(Ljava/lang/String;)Ljavax/servlet/RequestDispatcher; not found

The method getRequestDispatcher() was added in the 2.1 Servlet APIs.
Any suggestions? When commenting out the wrapper.classpath=d:\iSuites\Apache\Jsdk\lib\jsdk.jar line and inserting a 2.1 Servlet API the app still fails, same error. Is the API bundled in another jar file?
Still investigating myself, if anyone has run upon error please post a solution.
Thanks,
Jason

Jason,
Are you trying to develop a portlet? If so, please direct your question to the Portal Development Kit forum.
If this is a general question about iAS servlets, we hope to have an iAS forum available by the end of January. In the meantime, I'll request that someone from iAS product management respond to your question.

IllegalStateException: Internal Servlet Session Process Error Found!

 I keep getting the annoying error as listed, and the server also keeps reporting
 that I can only connect from 0 unique ip addresses. Has anybody else seen these
 type of frustrations on 8.1 sp2, or can explain them.
 With as much detail omitted for simplicity;
 Frustration 1.
 I have a 8sp2 server running all ok, occasionally after a redeploy of an ear file
 I attempt to load a jsp file, and the error below is thrown.
 The JSP has a bean which is session based, and as from following the stack trace
 it is around some weblogic code which tests if my license allows access to the
 http session (on a developer license). I then have to start another server instance
 and do a deployment of a v.simple war, and access this, then deploy the same war
 to the broken server and access that, then the initial jsp works fine. no code
 changes just environment stops, starts and redeploys!
 Frustration 2
 Server runs ok, tray and connect from two machines (I have an ldap server that
 wants to 'broadcast' messages to my server), error of too many connections.
 The ip connection issues can in most cases be removed with a server restart.

INSTALLING SERVLET API

How do I install the servlet api?

The servlet api gets installed with any web server that you install. For example if you are installing Jeeves(Java Web Server) you will find a file called servlet.jar which contains all the servlet classes. The path is ./JavaWebServer2.0/lib/servlet.jar.
Hope that helps.
