JSP Tag example pagehits.jsp NumberFormatException

I just upgraded my WLS 5.1 to SP4, but when I run the pagehits.jsp
          example, I got the following NumberFormatException. It was fine w/o
          SP4. I am very appreciated if anyone can help me to clarify that.

JSP Tag -- Including a JSP fragment in a Java Tag file

Hi all,
I have a query regarding JSP Tag file authoring by extending the TagSupport class. I would like to know if it is possible to include a JSP file fragment inside a Java file somehow.
Specifically, I have created a simple template tag, which adds a header and footer template to the resulting HTML page.
<bc:template>
Hello World!
</bc:template>produces for example
<html><body>
Hello World!
</body></html>Now I have two JSP fragment files (head.jspf and foot.jspf), and I want to do do something like
public class HtmlTemplateTag extends TagSupport implements TryCatchFinally {
public int doStartTag() {
    // somehow include head.jspf
    return EVAL_BODY_INCLUDE;
public void doFinally() {
    // somehow include foot.jspf
}Which means, I want to execute had.jspf and foot.jspf from the Java class file. I am not sure if it is even possible. If anyone can help me with this, it would be greatly appreciated.
thanks
nilesh

Your intention is to put a header/footer on pages in your web application?
There is another way to do it - specify prelude/coda jsp fragments in web.xml
Something like the following:
<jsp-config>
<jsp-property-group>
    <url-pattern>*.jsp</url-pattern>
    <include-prelude>/WEB-INF/jspf/head.jspf</include-prelude>
    <include-coda>/WEB-INF/jspf/foot.jspf</include-coda>
</jsp-property-group>
<jsp-config>

Why does people use JSP Tag for their JSP page? (Urgent)

I don't know what benifit if I am using JSP Tag.
If anyone knows, pls give me an idea and the advantage of using JSP Tag in JSP Page!
Thanks in advance!

You have to read a little about JSP, JSP stands for JavaServer Pages, you can use jsp tags and you can use java code. If you dont want to use jsp tags then you should just write html file, if you just want to use java, then write java class or a servlet.
The need for jsp arised because people were inserting html code inside a servlet class..a big no no..and a headache. JSP separate model from the view...read a little about MVC-2 model view controller pattern.
Also read some tutorial on this website...good luck

Custom tag in included JSP page cause exception (WLS 5.1 SP 9)

          An application use custom tags (JSP Tag extensions) in JSP page

          After we had installed Service Pack 9 for Weblogic 5.1

Register 12 VerifyError exception when compiling jsp with that jsp tag!

          Hi everybody,
          We implemented a tag which is charged with a simple task like just "out.println"s,
          on production with WL5.1 SP11,jdk1.2.
          Then we got java.lang.VerifyError exception which is also denoted at Giuseppe Madonna's
          mail on ( http://newsgroups2.bea.com/cgi-bin/dnewsweb?cmd=article&group=weblogic.developer.interest.jsp&item=6834&utag=
          ) that "java.lang.VerifyError: Register 12 contains wrong type"
          To be able to find the inconsistency in class files denoted at VerifyError exception,
          we delete the tmp dir. of web app resides in a war.
          Also the related java beans used in jsp tag and related jsp, are in a jar on our
          classpath and .tld file resides in the .war file of our web application.
          But also, I must define that it is our first tag implemented after we migrate to
          the .war file after the web application directory structure of same application(that
          old dir. also deleted), I know it is silly but, is it possible that WL can now refer
          to something related our previous directory structure of our app. like that old .tld
          file or classes?
          Or may it be related with the difference between jdk versions on the test and the
          production server?
          Any help will be really appreciated..
          Many thanks,
          Banu

Is a JSP Tag Library providing Oracle Financial look and feel available

We are going to use Oracle Financial as part of our future application.
That is why other parts of it (which we plan to develop using JDeveloper)
have to have the same Look and Feel.
Is a JSP Tag Library that provides Oracle Financial Look and Feel available?

Oracle Applications use BC4J, UIX, and JDeveloper.
The UIX framework implements the Oracle "Browser Look And Feel" (BLAF) that our Oracle Applications self-service applications use.
The UIX JSP tag library lets JSP developers do the same.

Urgent-how to access custom tag from jsp tag

I have a problem accessing a custom tag from a jsp expression.
Details: I have a custom tag that returns a string variable. I need to access that variable from jsp expression <%%>.
Can any body help me?

Tags don't "return" values as in the normal sense.
They can only support TEI (Tag Extra Information) that just stuffs a declared variable into the page's state.
For example, if the tag class had a public method called getValue(), you could do the following:
<xmp:mytag id="foo"/>
<%
out.println("value is " + foo.getValue());
%>

Problems in developing custom JSP tags

I have problems in debugging custom JSP tags. Sometimes the doStartTag is not called on tags but the doEndTag is called. I don't know why.
Thanks.

Fahr--
A word of caution -- NetUI did not ship a JSP tag SDK in 8.x, and
we're making no compatibility guarantees for custom JSP tags written on
the 8.x release and future releases.
You can accomplish the same sort of functionality with a combination
of the <netui-data:getData> tag and JSTL 1.0. This solution would
probably provide similar functionality and be more future-proof relative
to JSTL and the NetUI tags currently being developed in Beehive.
Hope that helps.

We are in the midst of creating our own JSP tags to work with datasources.
In an example where you would need to compare two different datasources how would you do this?
ie.
<prefix:isGreater dataSource="{pageflow.column1}" dataSourceToCompare="{pageFlow.column2}" />
How would I evaluate what column2 is since the tag will only resolve one data source
this.evaluateDataSource();
Any pointers you can provide would be appreciated, or if there is a library of jsp tags that evaluate objects using datasources already created, that would even be better.

How to use GX tags in a JSP?

Hi, everybody!
Our company have got a NAS 2.1 application (with AppLogic's and HTML templates) that it needs to be migrated to J2EE model. In this moment, we can't cover a complete migration from AppLogic to a J2EE, and furthermore, we have to maintain all the presentation layout and keep GX tag's in our templates.
From my point of view, AppLogic's must be translated into Servlets and HTML-template files could be renamed in JSP files, keeping GX tags.
Nowadays we are making this partial migration, but we've realized that JSP engine doesn't evaluate correctly JSPs with GX tag's.
Example
Servlet:
TemplateMapBasic tmpMap = (TemplateMapBasic) GX.CreateTemplateMapBasic();
tmpMap.putString("nombre","Alberto");
req.setAttribute("GX_MAP",tmpMap);
// Call JSP
getServletContext().getRequestDispatcher("/example.jsp").forward(req,res);
JSP:
%gx type=cell id=nombre%
%/gx%
Result:
%gx type=cell id=nombre%
%/gx%
Insteof of appearing Alberto, it shows the tag.
Does anybody know what it is happening?
Do I need to include some tag library into the JSP?
Thanks in advance.
Alberto
PD: We are using iPlanet Application Server 6.0 SP4.

Hello again,
Just tried this and got the same problem, copy the file into your actual web application so the link becomes
continue
Or put in a sub directory as you see fit.
I have never tried to open files on the pc in this way, only files under my web site, but it seems as though the browser will not allow the execution of files on your computer.
Thinking about it, javascript is not able to execute such processes either, it is a security constraint.
Would you want websites to be able to execute jobs on your local PC??

          WLS 5.1, sp9 pre-release, solaris 2.7, WLCS 3.2
          JSP compile fails with the exception...

          It could just be me - I an un-jarred a version of weblogic-tags-510.jar where WLS
          could find it.

Custom JSP Tags for Weblogic

Hi,
          I have several questions regarding this topic:
          1) Does Weblogic 5.1 supports Custom Tags ? If so, are there any known
          problems ?
          2) Does Weblogic come with any tag libraries (for loops, if, etc) and where
          can I get them ?
          3) Are there any tag libraries out there (JRun, for example) that have been
          successfully run on Weblogic ?
          Any help would be much appreciated.
          Thanks,
          Jamie


As there seems to be general interest, a link would probably be a great
          help.

Using ViewObject with a foreach tag in a jsp

Hi guys I have the following scenario:
1- I call a certain .jsp page
2- a controller class (extends servlet) is called, this class: takes a view object, executes it's query, forwards the result to the jsp page.
3- jsp page has a foreach tag that iterates over the query result.
My problem is that foreach tag only takes list or array in its "items" attribute.
Now is there a way to put the view object result in an array/list? in other words in my servlet what should I put in the request so that the foreach tag can iterate over the rows of the query. Thank you in advance for the reply.

Thank you for the reply.
But my application is not a web based one.
I am developing a framework (as swf) in which some other swf files (target files) are played as movie clip. Since the framework swf should be considered as a general one, no direct linking to the other swfs preferred. I follow some (my own) rules to get things worked. For example, I need to show a simple movie cilp as the title in the framework. This movie clip will be different in different target swfs, and they will be stored inside the target swfs itself. I was thinking about giving them a unique id (eg. title_id) and after loading the target swfs, show their titles (movie clips) in one of the framework's empty movie clip (using attachMovie).
Could please suggest me any idea to get things work?

Jsp tags in .html pages

Hi
Is possible to put jsp tags in pages .html?
I try this example:
<html>
<head>
<title></title>
</head>
<%
out.print("teste");
%>
<body>
</body>
</html>
and the result in the page is the jsp code. Tomcat don't print "teste", print out.print("teste");.
Is possible to do this.
Thanks in advance.
Lu�s Matos

What do you expect to happen? Who would you expect to print anything? Your browser is the only instance that reads HTML, and it's not a servlet container. JSPs have to be compiled and executed by such a container like Tomcat.

uix:table using JSP tags

I cannot figure out how to bind a dataobject list using the <uix:table> tag. Could someone please help me with this.
Jeff Driskell

Do you mean that you already have a DataObjectList which you want to set as the <uix:table>'s tableData attribute? If so, I believe you have two choices:
1. You can use a scriptable variable for the table and call setTableData() explicitly on the TableBean.
2. You can use a scriptable variable for a dataScope and register a DataProvider which provides access to your DataObjectList. Then, you can use the tableDataBinding attribute of the <uix:table> tag to bind to your DataProvider.
Examples of both of these techniques are provided in the "Scriptable variables" section of the "UIX JSP Tag Libraries" section of the UIX Developer's Guide.

Are not interpreted JSTL tags in a JSP page including in a servlet.

Hi people,
I have a project where una page (index.jsp) includes a servlet (MyServlet), that consult a persistence class and get a List of objects (Users),
then the servlet passes the List to a Request object and includes another JSP page (showUsers.jsp). And this is conceptually correct, but don´t works, the JSTL tags are not interpreted in showUsers.jsp.
This is my code...
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<c:out value="Show me some things index.jsp"/>
<div style="border-color:red; border:solid; padding-left:60px">
      <jsp:include flush="true" page="pepe/MyServlet"/>
</div>
</body>
</html>...and the Servlet...
public class MyServlet extends HttpServlet
     public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException
          UserManager um = new UserManager();
          List users = um.getUsers(); //This use Hibernate to return a Users List
          request.setAttribute("users", (ArrayList) um.getUsers());
          request.getRequestDispatcher("/showUsers.jsp").forward(request, response);
}...Finally, we have the showUsers.jsp file....
<c:out value="Show me some thing showUsers.jsp"/>
<table>
     <tr>
          <th>ID</th>
          <th>Name</th>
          <th>e-Mail</th>
          <th>Type</th>
     </tr>
     <tr>
          <c:foreach items="${requestScope.users}" var="user">
               <td><c:out value="${user.id}" /></td>
               <td><c:out value="${user.name}" /></td>
               <td><c:out value="${user.email}" /></td>
               <td><c:out value="${user.type}" /></td>
          </c:foreach>
     </tr>
</table>This i get as result page...
ID      Name      e-Mail      TypeFinally, this is the code of showUsers.jsp...
<c:out value="Show me some thing showUsers.jsp"/>
<table>
     <tr>
          <th>ID</th>
          <th>Name</th>
          <th>e-Mail</th>
          <th>Type</th>
     </tr>
     <tr>
          <c:foreach items="[src.User@18f729c, src.User@ad97f5, src.User@d38976, src.User@1e5c339, src.User@17414c8, src.User@7a17]" var="user">
               <td><c:out value="" /></td>
               <td><c:out value="" /></td>
               <td><c:out value="" /></td>
               <td><c:out value="" /></td>
          </c:foreach>
     </tr>
</table>Somebody can help me?
Many thanks,

I assume in your web.xml, you have ''pepe/MyServlet' defined as a servlet tag and servlet map tag? Without that, I don't think your JSP will find the servlet. I'm >not sure you need it in web.xml since I never call a servlet from a JSP page.
I suggest putting System.out.println() throughout your servlet code and out.println() in your JSP pages to see exactly what is called and when.
As a general rule, JSP files are to display data only, and submit back to a servlet. The servlet does all the business logic and dispatches to the appropriate >JSP page. The JSP shouldn't have any business logic. Including the servlet looks kinda like including business logic. Actually, in a MVC design, your >presentation, control, busines, and database layers have their own isolated responsibilities.
I suggest the servlet put data as one java bean in request scope via request.setAttribute() and dispatch to the JSP page. The JSP page gets the data via ><useBean> tag. The JSTL gets the variables from the useBean tag and uses the data from there to display it. Really, this is my web.xml file...
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
     version="2.4">
     <servlet>
          <servlet-name>MyServlet</servlet-name>
          <servlet-class>src.MyServlet</servlet-class>
     </servlet>
     <servlet-mapping>
          <servlet-name>MyServlet</servlet-name>
          <url-pattern>/pepe/MyServlet/*</url-pattern>
     </servlet-mapping>
</web-app>Regarding putting System.out.println() and out.println(), i did it and thats works.
Respect of your last comment, I am not a expert in MVC, but I understand that the view layer can make calls to the Controller layer, I am wrong?
evnafets wrote:
It's not. However thats not code, but the generated HTML.
As Balusc pointed out it's the result of running this JSP page without importing the tag library at the top.
Because the tag library is not declared, it treats the <c:forEach> and other tags as template text, and basically ignores them.
It then evaluates the ${items} attribute as an expression in template text, calling toString() on it.
Cheers,
evnafets      The file showUsers.jsp are included into the index.jsp page, that's have the header taglib. Could this works?
