Attributes of page directive?

what is the purpose of the following attributes of page directive
1-extends
2-info
3-session

http://java.sun.com/products/jsp/tags/12/syntaxref1210.html#15653
extends="package.class"
The fully qualified name of the superclass of the Java class this JSP page will be compiled to. Use this attribute cautiously, as it can limit the JSP container's ability to provide a specialized superclass that improves the quality of the compiled class.
session="true|false"
Whether the client must join an HTTP session in order to use the JSP page. If the value is true, the session object refers to the current or new session.
If the value is false, you cannot use the session object or a <jsp:useBean> element with scope=session in the JSP page. Either of these usages would cause a translation-time error.
The default value is true
info="text"
A text string that is incorporated verbatim into the compiled JSP page. You can later retrieve the string with the Servlet.getServletInfo() method.

ER: organize imports in an "import" attribute of a JSP page directive

Hi,
it would be useful to see packages/classes hierarchy when changing the "import" attribute of <%@ page %> directive. It might be as well to have all possibilities of imports processing as in .java classes (autoadding, remove unused import, etc.)
Thanks in advance.

Hello Scott,
          First, you have to define this page directive in your static page or JSP
          page :
          <%@ page contentType="text/html; charset=UTF8" %>
          Check your your weblogic.properties file for the following settings:
          weblogic.httpd.inputCharset specifies encoding used when changing into the
          internal code of Java from the parameter of the browser's request. If you
          use Shift_JIS in HTML or JSP, please set
          weblogic.httpd.inputCharset./*=Shift_JIS.
          weblogic.codeset specifies encoding used when jDriver stores data in an
          Oracle database and it changes into the character code of a database from
          the internal code of Java. If you use ja16sjis in Oracle database, please
          set the same encoding as NLS_LANG to weblogic.codeset.
          Hope this helps

Page directive: can't have multiple occurrences of language

Do anybody know what is the meaning of the following exception when running the JSP??

Problem with errorPage in page directive tag while proxying request from iPlanet to WebLogic

          Hi,
          We are using iPlanet 4.0 as the webserver and WebLogic 5.1 as the application server on different solaris machines. We have put our JSPs in the weblogic application server and proxy the requests from iplanet to weblogic.
          We are facing a problem with the errorPage in the 'Page Directive' tag of the JSP. We have given xxx.jsp as an 'errorpage' parameter in the page directive tag. If we directly access the JSP from the WebLogic, and there is an system error, the error page specified in the JSP is getting displayed. But if we access the JSP from iPlanet and there is an system error, instead of displaying the error page, iPlanet is asking whether we want to download the file. If we say yes it downloads the actual JSP code itself. We have defined the mime types in obj.conf file as well as mime.types for the iPlanet.
          If anyone knows how this can be solved, it would be of great help
          Regards,
          Krish


How did you configure the obj.conf file? proxy by mime type or ppath? It
          seems errorPage.jsp was not proxyed and treated as a unknown mime type.

Page directive with UTF-8 charset??

Hello,
          I try to implement the following jsp with weblogic. It displays A???C on the
          browser when the encoding is set to Unicode(UTF-8).
          When I change the browser encoding to Western European, it works fine.
          <html>
          <head>
          <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
          <title>Trying</title>
          </head>
          <body>
          <%
          String original = new String("A" + "\u696D" + "\u00f1" + "\u00fc" + "C");
          byte[] utf8bytes = original.getBytes("UTF8");
          String roundTrip = new String(utf8bytes, "UTF8");
          %>
          Original = <%=original %>
          RoundTrip = <%=roundTrip %>
          </body>
          </html>
          I found that it ignores the first two 00 when handle \u00xx character.
          However, if I add the following page directive at the beginning, it works
          fine.
          <%@ page contentType="text/html; charset=UTF-8" %>
          My question are
          1. why it trim the first two digit ("00")?
          2. what the weblogic did when I add the page directive?
          3. Is that mean the line <meta http-equiv.....> cannot work?
          4. Is there any alternative instead of adding the page directive line?
          I use WL6.1, win2000. Please help.
          Thanks a lot.
          Regards,
          kfchu


String original = new String("A" + "\u696D" + "\u00f1" + "\u00fc" + "C");          > I found that it ignores the first two 00 when handle \u00xx character.
          > 1. why it trim the first two digit ("00")?
          I can't tell what you mean. According to the JLS, the "\uxxxx" construct is
          processed in a pre-lexical step. That means that your code is the same as
          writing:
          String original = new String("A" + "?" + "?" + "?" + "C");
          (Where I used a question mark instead of looking up and writing in the
          actual character values.)
          The reason why it is 00xx is that the "\u" construct requires the data in
          UTF16 format (the 2-byte encoding of Unicode characters which you know as
          Java's "char" type).
          To see how this data is encoded / decoded, you can look at the Java sources
          for java.io.DataInputStream and DataOutputStream.
          > 4. Is there any alternative instead of adding the page directive line?
          Yes! You can use the Response method directly:
          public void setContentType(java.lang.String type)
          (That's all that the JSP does anyway.)

"import" in the JSP's Page directive - referencing a package

I have my JSP file in WEB-INF. And my .Java file in the "Project parent folder"/src/com/user/faq.
My Page directive in the JSP looks something like,
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1" errorPage="errorPage.jsp" import="com.user.faq.FaqCategories"%>
And JSP won't compile, saying com.user.faq.FaqCategories is not found.
Any help on this will be appreciated. Thanks!

JSP won't compile, saying com.user.faq.FaqCategories is not foundSo it isn't on the classpath when compilation occurs. So fix that.

In order to change your Firefox Configuration please do the following steps :
# In the [[Location bar autocomplete|Location bar]], type '''about:config''' and press '''Enter'''. The about:config "''This might void your warranty!''" warning page may appear.
# Click '''I'll be careful, I promise!''' to continue to the about:config page.
# Look for '''bidi.browser.ui''', change its value to '''true''', restart Firefox, then right click to see the '''Switch Page Direction'''

Dreamweaver rewriting my page directives

Hi there all,
Quite a straightforward question here. I'm in the position
where I'm having
to use both Dreamweaver (CS4) and Microsoft Visual Studio
2008 to create an
asp.NET application.
VS2008 for the coding part and Dreamweaver for everything
else, mainly
because I prefer the Dreamweaver interface for building and
styling a site.
I'm also using the templates mechanism within Dreamweaver to
manage the
site.
The problem is when I make a global change to a template
Dreamweaver keep
defaulting my page directives on all my site pages thus
breaking the
code-behind link between .aspx page and .vb files.
How can I stop Dreamweaver messing with the page directives?
Would be most grateful for some guidance please.
Cheers,
@ndyB

Good luck. Let us know how it goes.
