Blank JSPs.

Hello, all.
          Maybe someone can give me a hand. Don't see anything else similar here... so
          hopefully it is just something I've overlooked.
          The problem:
          WebLogic works (alright.. that isn't a problem)... =) We've setup a
          web-application following the instructions as they show here
          http://www.weblogic.com/docs51/classdocs/webappguide.html
          And all seems fine... we have ported from another package without much
          trouble. The issue comes when we try to edit a JSP or servlet... we thought
          it would re-compile on the fly... but it isn't... the servlets appeared to
          get called.. but they just return '<HTML>' and that's all.
          So change one JSP... and the whole app becomes a white background.
          Since we are not directly calling JSPs (or at least not referencing them in
          a URL).. but are instead calling servlets which use the JSPs... do we need
          to set the re-generate settings in weblogic.properties? We have the
          servlet_reloadCheckSecs set in the web.xml. (to 2)..
          sigh... deadlines. =) ANy ideas people
          Thanks,
          D.Parker

The directive given in the following document for reloading servlets is
          incorrectly
          written. It should be weblogic.httpd.servlet.reloadCheckSecs=10
          Let us know how it goes.

Design View blank, JSP and Java views fine

I'm running JSC 2.1, I have 2 gig of memory. I'm not able to see the design view on one of my jsps, but the error message in the log isn't very helpful.
I did a cut-and-paste from another jsp view in another file -- is there something else I have to copy? If so, what and where to?
Any help appreciated.
Stack trace is below (I get five of the same errors with different line numbers; I'm only including one stack trace here):

I figured out the problem. The Java code had gotten out of sync with the jsp code, so the design view didn't know how to render the components. It's a pain to fix, but it can be done. Go through your jsp code component by component, and make sure there are declarations, getters, and setters for each id in the components. Also make sure the java code doesn't contain declarations, getters, and setters for any components that you didn't create (you can see these in the jsp view at the bottom of the file).

Struts tiles to create event based loading of tiles on a JSP

Hi All,
I am working on a web app where I am using struts tiles to create my JSPs. I have tiles for header, footer & nav bar.
Now I want to break up my JSP body in multiple tiles. It is required that I insert only one body tile initially, say body1, which contains few hyperlinks. Depending on which link is clicked, I would attach another tile (body2) below the first one. Can any advanced tiles user inform me if it's possible with struts-tiles, & if yes how?
Thanks.

Tiles is basically used to overload the jsp pages and reuse them.
In your tiles-defs.xml file:
//Tiles for header, footer and nav bar goes here
//Tiles for body1 and body2 goes here
<definition name="BodyTile" page="/yourPage.jsp">
          <put name="body1" value="/blank.jsp" />
          <put name="body2" value="/blank.jsp" />
</definition>

Now create a customized tile for your module. Mapping has to be done in struts-config.xml.
Notice that the definitions here extend the tile from tiles-defs.xml, i.e. "BodyTile"
<definition name="ActionOneWithBodyOne" extends="BodyTile">
    <put name="body1" value="/yourPage1.jsp" />
</definition>
<definition name="ActionTwoWithBodyTwo" extends="BodyTile">
    <put name="body1" value="/yourPage1.jsp" />
    <put name="body2" value="/yourPage2.jsp" />
</definition>Now when you first load the page forward it to "ActionOneWithBodyOne" and it displays you just your body1.
When ever u click a link on body 1, after performing the action populate the form bean corresponding to yourPage2.jsp and forward the action to "ActionTwoWithBodyTwo".
Hope that helps!!

How to have a popup in Jsp Dynpage

Hi All,
I am having a JSP dynpage project working fine.
I now need a popup on click of a button in a iview (JSP).
I created a complete new JSPDynpage component with Bean etc.
I use the below code
window.open('project.componentname') to have a popup.
and in portal. xml I define the properties ComponentType & JSP.
the window pops up but with error at all times even for a blank JSP,
your help would be well apprictiated at this stage of my project situation.
I need a popup window where that popup is not just a confirm message but a process with several events and DB access.

Removing scrollbars on the JSP page of frames created by included JSP files

Hi All,
In the iternet sales B2B application which we are developing, has a blank JSP file. Wherein we are adding other JSP files on it, loading trough JS.
When we are adding it is making the various jsp files in the form of the frames, and each frame has different JSP page. So it is adding scrollbars on each frame if the size of the page exceeds the size of frame.
we don't want the scrollbars. Kindly suggest to remove these scrollbars, and all the pages should look as a single JSP page.
Thanks & Regards
EKta

Hi

where again...extending some standard definition by overriding ..

It's not nice to highjack someone elses thread. I posted a reply http://forum.java.sun.com/thread.jsp?forum=45&thread=552915 (though I shouldn't have, shoulda done it here). if you have questions post them to this thread instead. Leave the other one to the OP's question.

Linking between two IFRAME tags on the same JSP page

I have a JSP (lets call it �PAGE_A.jsp�) that contains a table� the <TD> tags hold IFRAME tags with an initial �src� referencing a �blank.jsp��
�

<table width="100%">
<tr>
<td>
<iframe id='report_view' name="report_view" width='60%' height="500" frameborder="0" src='blank.jsp'>
</td>
<td align="left">
<iframe id='drilldown_view' name="drilldown_view" width='40%' height="500" frameborder="0" src='blank.jsp'>
</td>
</tr>
</table>
�
At a point, the user initiates a call to a servlet, and the output (PAGE_B.jsp) is returned to the first IFRAME �report_view�.
PAGE_B.jsp contains HTML anchor tags that call the servlet again, this time the return target is the second IFRAME �drilldown_view� :
( Some Text).
Clicking the link produces the desired page to be generated and displayed in the correct IFRAME running IE 5.5, however, the same code under NETSCAPE 7.x causes the �linked� page to open in a new browser window.
I have deduced that this effect may be due to the NETSCAPE browser �thinking� that the targeted IFRAME (�drilldown_view�) should be a �child� of the IFRAME that contains the link (�report_view�), instead of another IFRAME belonging to PAGE_A.jsp. Under this circumstance, NETSCAPE cannot find the �target�, and thus redirects to a new browser window.
Q: Is there a way to specify the �parent� of the �iframe� in the anchor�s �target� attribute?

target in a link shouldn't care, as long as the IFRAME is in the same window... It should be able to find it.
Otherwise, you could explore using Javascript to get a reference to the object by specifying the path:
var oIFrame = top.document.getElementById('drilldown_view');
oIFrame.src = 'somepage.html';
that could work.. I've used that type of thing before.

Error in running JSP files

Hi,
This is the first time I post message on the forum. The problem is that when I run the JSP files with Tomcat 4.0.1. It give the error messages. But I have put the class files under the root, such as ...\WEB-INF\classes, however, it doesn't work. Also I have set the classpath for tomcat. Is there any step I have missed?
Please give me some solution as the problem has annoyed me for a long time.
The error message is:

Confused yet.
Here's the deal. Every Java class is in a package. If it is not declared the it is the default package but the default package is based on the directory it is in.
The DBSession class is in WEB-INF/classes and the jsp gets compiled into a class file that is placed in a different directory. Since the two class files are in different directories they are in different default packages. Thus the import.
Most people don't run into this because they put their tags into packages and import the packages.
To make everybody happy, put your tag in a package, recompile it and then import the package.

JSF,Tiles, Sun App Server and NetBeans 5.5

hi all,
here is my environment :
1.Server - Sun Application Server (Running On Suse Linux OS)
2.IDE - NetBeans 5.5
3.Project - JSF with Tiles
here i found topic about tiles and jsf :
http://forum.java.sun.com/thread.jspa?threadID=643536&messageID=3792238 but i think that Tiles is best alternative for JSF Layout Manager (It's my mind).
is there anybody help me how to integrate tiles with jsf ?
here is my example :
1.web.xml :
    <servlet>
        <servlet-name>Tiles Servlet</servlet-name>
        <servlet-class>org.apache.struts.tiles.TilesServlet</servlet-class>
        <init-param>
            <param-name>definitions-config</param-name>
            <param-value>/WEB-INF/tiles-def.xml</param-value>
        </init-param>
        <load-on-startup>2</load-on-startup>
    </servlet>2. tiles-def.xml :
<tiles-definitions>
         
     
     
     <definition name="global.layout" path="/pages/Mylayout/layout.jsp">
          <put name="title" value="Magti Billing System" type="string"></put>
                <put name="subtitle" value="Magti Billing System" type="string"></put>
                <put name="header" value="/pages/Mylayout/header.jsp"></put>
          <put name="subheader" value="/pages/Mylayout/sub_header.jsp"></put>
          <put name="footer" value="/pages/Mylayout/footer.jsp"></put>
                <put name="body" value="/pages/Mylayout/body.jsp"></put>
                <put name="left_menu" value="/pages/Mylayout/left_menu.jsp"></put>
     </definition>
</tiles-definitions>3.and then i have 5 blank jsp pages : body.jps, footer.jsp, header.jsp, layout.jsp, left_menu.jsp, sub_header.jsp.

Hi,
I'm trying to use Tiles with NetBeans 6.0. I used a similar set up as the other writer did, except for the JSP:root part:
<jsp:root version="2.1"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:jsp="http://java.sun.com/JSP/Page"
xmlns:webuijsf="http://www.sun.com/webui/webuijsf"
xmlns:tiles="http://jakarta.apache.org/struts/tags-tiles">
It complies and deploys OK, except it renders a blank page. The source code of the page is below. It seems that the "tiles:insertDefinition" was not expanded. Would you share some lights on how you get it to work. By the way I did not use shale-tiles, do I need it?
Thanks in advance.

Stand Alone OC4J and Java's Comm API

I am using the Java Comm API alongwith a servlet. The code simply gets the required ports and displays it in a JSP page. The program is developed using Jdeveloper 9. It works fine with embedded OC4J but a blank jsp page is displayed when deployed in in standalone OC4j instance on the same machine. I have correctly copied the required wincom32.dll, java.comm.properites and comm.jar to the jre/bin, jre/lib and jre/lib/ext respectively. What could be wrong.
Thanks
MMN

Try setting the OS PATH env variable to the directory where the .DLL is located before you launch the container. Or else put the .DLL in a directory which is in the existing path.

Query to generate an xml output hierarchically

Hi I need to write a sql query to generate an xml hierarchically for a tree menu. I have one self-joined table that holds menu hierarchy.
Following is a sample data in a table.
MenuID    MenuName       ParentID     href
1            File
12           Open              1     Open.jsp

5            Win               1     Win.jspFollowing is the sample output want to generate:
<?xml version = '1.0' encoding = 'windows-1252'?>
<menus>
    <menu name="File" id="1">
        <menu name="Open" id="12" href="Open.jsp"/>

     </menu>
    </menu>
    <menu name="Doc" id="3" href="Doc.jsp"/>
    <menu name="Tools" id="4" href="Tools.jsp"/>
</menus>Thanks

You can use SYS_CONNECT_BY_PATH to get the complete hierarchical path to an object, and then order by that. Here is an example:
with menutbl as
(select 1 as MenuId,'File' as MenuName, null as ParentId, null as href from dual
union all
select 12,'Open',1,'Open.jsp' from dual
union all
select 11,'New',1,null from dual
union all
select 21,'Program',11,null from dual
union all
select 61,'Program2',11,'Program2.jsp' from dual
union all
select 31,'Blank',21,'Blank.jsp' from dual
union all
select 2,'View',null,null from dual
union all
select 22,'Printer',null,null from dual
union all
select 28,'Printer2',22,null from dual
union all
select 30,'Printer3',28,'test.jsp' from dual
union all
select 23,'Doc',null,'Doc.jsp' from dual
union all
select 4,'Tools',null,'Tools.jsp' from dual
union all
select 5,'Win',1,'Win.jsp' from dual)
select * from (
select menutbl.*, SYS_CONNECT_BY_PATH(MenuId, '/') as path from menutbl start with parentid is null connect by
NOCYCLE PRIOR MenuId = ParentId) order by path;this prints
1     File               /1
11     New     1          /1/11
21     Program     11          /1/11/21
31     Blank     21     Blank.jsp     /1/11/21/31
61     Program2     11     Program2.jsp     /1/11/61
12     Open     1     Open.jsp     /1/12
5     Win     1     Win.jsp     /1/5
2     View               /2
22     Printer               /22
28     Printer2     22          /22/28
30     Printer3     28     test.jsp     /22/28/30
23     Doc          Doc.jsp     /23
4     Tools          Tools.jsp     /4I guess that you can take over from here and add html elements around the text...

Java.lang.IllegalStateException: internal assert

I am using Sun One Application Server 6 and JBuilder X. Everything works fine till building the project. While building the deploy modle, I get this error twice for every jsp page in the project.
blank.jsp: java.lang.IllegalStateException: internal assert
I am using jdk 1.3.1.12.
Please advise.
Thanks
Peter

I guess your jsp is not registered properly and thus u are seeing this error. May be you want to start your kjs in debug mode and see where exactly is it throwing this exception.

Could you help me about c:forEach JSTL tag!

hi everybody!
Well I'm having a trouble when I use <jsp:forEach> tag to write the elements of object from a ArraylList:
that is the object I store in the data froom the bank to be shown:
package teste;
public class Detalhes {
    private String titulo;
    private String autor;
    private Double preco;
    private int codigo;
    public Detalhes(String titulo, String autor, Double preco, int codigo) {
        this.titulo = titulo;
        this.autor = autor;
        this.preco = preco;
        this.codigo = codigo;
    public String getTitulo(){
        return titulo;
    public String getAutor(){
        return autor;
    public Double getPreco(){
        return preco;
    public int getCodigo(){
        return codigo;
}and that is the class where I get the data from the database, store it in a object (Detalhes) and get the arrayList (list);
package teste;
public class Data {
    Connection con;
    Detalhes detalhes;
    ArrayList list;
    int codigo;
    public Data()throws Exception {
        try {
            Class.forName("org.gjt.mm.mysql.Driver");
            con = DriverManager.getConnection("jdbc:mysql://127.0.0.1/Loja?user=root&password=131283");
        } catch (Exception ex) {
            throw new Exception(" Database not found!!" +
                ex.getMessage());
    public ArrayList getList(){
        try {
            String selectStatement = "select * from produto";
            PreparedStatement prepStmt = con.prepareStatement(selectStatement);
            ResultSet rs = prepStmt.executeQuery();
            while(rs.next()){
                 detalhes = new Detalhes(rs.getString(1), rs.getString(2), rs.getDouble(3), rs.getInt(4));
                 list.add(detalhes);
            prepStmt.close();
            Collections.sort(list);
        }catch(Exception e){
       return list;
}    the piece of my jsp page is that:
<p><b><h1>Resultado:</h1></b></p><br>
<jsp:useBean id="dataSource" class="teste.Data" scope="page" >
       <jsp:setProperty name="dataSource" property="codigo" value="${param.theCode}"/>
</jsp:useBean>
<c:forEach var="book" begin="0" items="${dataSource.list}">
    <p><b><h1><font color="red">${book.titulo}<h1></b></p>
</c:forEach>The result is a blank jsp with no data, have you any advice?
What's wrong? I'll greatfull!!!!

First thing to do is to store the result of the list call to a variable so you don't call the getList method all the time:
<c:set var="bookList" value="${datasource.list}"/>
<c:forEach var="book" items="${bookList}">
Check if anything is added to the List, or if the List is null:
<c:out value=${bookList}"/>
And assume that you are getting an error in your SQL, which you are catching and ignoring when you do:
        }catch(Exception e){
        }            Instead of doing nothing, report the error some-how. Maybe using System.err or System.out (or better yet a real log). Then look at your Server's standard output log to see what may be happening.
If all else fails, don't catch the exceptions - throw them so you get an error in your default server logs or on the web page itself.

Deploying ajax calls into framework

Hi, currently running Sun Web Server 7.0 on windows and a flavor of unix

any ideas?
Thanks, payam.

Apparently something -- perhaps SweetDEV RIA itself -- is storing non-serializable data in sessions. You've configured Web Server to use the Web Server 6.0 FileStore. Because FileStore serializes sessions to files, it doesn't work with sessions that contain non-serializable data. You'll either need to stop storing non-serializable data in sessions or use a different session store.

Blank JSPs.
