Delpoying JSP Tags on Resin

Hi there,
Can any one help me, guiding in Deploying JSP Tags on Resin .. where to place class files, JSP files , xml file and tld files.
Thanks in advance,
Naveen

Hi, I've deployed mine on Resin, it was the exact same as Tomcat, except for the fact that it's faster and I didn't need to restart my Context :)
I put the jar in the /WEB-INF/lib folder
the tld in the /WEB-INF/tlds folder
and the jsps in the doc root.
It should be the same no matter which app-server you use.

Include jsp tags

I am having a problem relacing the include file of let's call it a
header.jsp in a menu page named menu.jsp.
So in my header.jsp file let's say I do something simple like
<table>
<tr><td><jato:href name="first">First Option
</jato:href></td></tr></table>
and so on....
And in my main.jsp I have a simple include at the top of my page
like so
<html
<body>
<%include file=header.jsp%>
etc.
Now when JRun 3.0 makes the include replacement, it seems to have a
problem where it tells me
Servlet error 500
com.iplanet.jato.view href : taglib navigation not found
BUT when I take out the jato tags in the include file...I can get
JRun to make the replacement perfectly....
Does anyone else have this problem and if so how did you get around
it?

Sorry to bother you again, but I couldn't find anything that looked strange
is this file. Can you send us the original file at our personal email
addresses? I'd like to see exactly where the compilation error occurs and
it's not possible with the file inlined here.

Hi Suket,
I just retested something very similar to this in 1.0.
Essentially, i took an existing page which included a tiledView.
I moved the TiledView jsp block into an entirely separate jsp file.
I then replace the TiledView jsp block in the original jsp with aninclude
<%@ include file="TiledGetOrders.jsp"%>
It worked like a charm.
So I am not sure what is wrong in your case.
Could be a jrun bug?
I have tested in resin 1.2.1
To do proper analysis, we would need to see
1. The intermediary .java file that the jsp engine creates, andthen tries
to compile.
C:/Program

Can you send that to us?
Incidentally, although we do not think a problem there would causethe
compile time error you are seeing,
i am curious about your file value.
<%@ include file="/IPP/ipp/pgFooter.jsp"%>I did not need to use a qualified file name, although my includetarget file
was in the same directory as the
page that was including it. What is the file system relationshipbetween
your top level page "pgHelp" and the include
target "pgFooter".
Are they in same or diff directories?

Craig & Eric--
(If you're not interested in the resolution to the problem Craigposted,
please skip ahead to the section in which I describe the
preferred
technique
for including headers and other common content in a JATO page.
This
discussion is very important because I introduce the concept of"view
compostion", in which JATO pages are composed of modular andreusable view
components. This is one of the most powerful new features of
JATO,
and a
capability that simply wasn't possible in NetDynamics.)
Posted Problem Resolution
Craig & Eric, from what I can tell, you are both trying to
include
a full
view bean in a parent page at translation time. This is notpossible, as
you can see from the compiler errors you get. There are
collisions
when
multiple top-level tags are included in the same JSP.
When I said earlier that you needed to use a translation-timeinclude
instead of a run-time include, I was assuming that you were
trying
to
include a fragment of HTML/JSP in the parent page. By
fragment, I
mean HTML
or JSP content that does not declare a view bean or form, but
rather
references views contained within the parent view bean. If youwant to
include a full page (JSP + ViewBean) in another page, then you'dneed to use
a run-time include. A run-time include temporarily pauses therendering of
the current page, and sends the full request to the included
page
as if it
were a separate client request. The resulting content from theincluded
page is inlined into the parent page's content, and processing
of
the parent
page then continues.
Now I realize after thinking about it a bit that we may not have
sufficiently provided for full page includes because of some
late-
breaking
changes in the request context handling. After some basic
testing,
it
appears that if you try to include one JATO page in another byreferencing
the JSP, the included page will cause a class cast exception tooccur.
There may also be problems because the request context on theincluded page
will not have been set. In any case, full JATO page inclusionlooks like
it's an issue we're going to have to address with some fixes
before
it will
work properly. My apologies. (One workaround if this is
necessary
is to
make the included view bean a child view of the parent view
bean.
I won't
go into that however).
How to Include Common Content
Now, on to the discussion of the preferred way of including
common
content
in a JATO page. Let's say you have a common header you want toinclude in
one or more of your JATO pages. Because of the issue I notedabove, and the
fact that the header is not really independently displayable,
you
don't want
to do a run-time include (which, remember, would necessitateincluding a
full JATO page).
Instead, you should include the header as an HTML/JSP fragmentusing a
translation-time include. Depending on whether your header hasdynamic
information, you can do one of two things. If the header is
just
static
content and/or set of links, you can just reference the HTMLfragment in the
parent HTML directly, and you won't need any kind of view or
view
bean to
back it, or any reference to anything in JATO.
If you need some dynamic info in the header, like the module URLfor a link,
you can reference the parent page's view bean for this
information
by simply
including references to the parent page's implicit JSP variables(viewBean,
currentVIew, and currentTiledView). For example:
Parent JSP:
<jsp:useBean id="viewBean" class="..."scope="request"></jsp:useBean>
<jato:useViewBean className="..." fireChildDisplayEvents="true">
<%@ include file="MyInclude.jsp" %>
</jato:useViewBean>
Included content (MyInclude.jsp):
... viewBean.getRequestContext().getModuleURL() ...
The final HTML with the included content would then look like
this:
<jsp:useBean id="viewBean" class="..."scope="request"></jsp:useBean>
<jato:useViewBean className="..." fireChildDisplayEvents="true">
... viewBean.getRequestContext().getModuleURL() ...
</jato:useViewBean>
MyInclude.jsp will be inlined in the parent JSP before it istranslated to a
servlet. Note that it does not include the full HTML tags
normally
found in
an HTML file--there are no <html>, <head>, or <body> tags
because
it is not
expected to be used outside of an include page. In effect,
this is
the
equivalent of a server-side include (SSI).
Now, if you need truly dynamic info in the header, like say youwant to
display the user's name and SSN, then you'd likely want to
embed a
child
view in the parent view bean which will encapsulate & provide
the
necessary
information. This is in contrast to actually making these
fields
direct
children of the the parent view bean, which would be a tedious
and
error
prone task on every page you wanted to include this information.Let me try
to contrast these two approaches with a diagram of parent-child
relationships:
Here's the bad way:
ParentViewBean (ViewBean)
|
+-- UserFirstName (StaticTextField)
|
+-- UserSSN (StaticTextField)
In this situation, you'd need to provide the logic to populatethese fields
in every view bean on which they appeared. This is tedious andessentially
eliminates the "common"-ness of the content (this is also whatNetDynamics
forced people to do).
Now, the better way:
ParentViewBean (ViewBean)
|
+-- MyHeaderView (MyHeaderView.java)
|
+-- UserFirstName (StaticTextField)
|
+-- UserSSN (StaticTextField)
In the better way, you can see that the header information isencapsulated
in an instance of "MyHeaderView", which is a subclass ofContainerViewBase
or one of the other ContainerView subtypes. The population of
the
data
fields is encapsulated in that view, and the parent view need
not
know
anything about what's actually being displayed by that view.
Thus, you can see that MyHeaderView, in conjunction with a
snippet
of JSP
content in a companion file, is completely modular and can beembedded in
any parent view bean on which you want the header to appear.
The
only
requirement is then to include MyHeaderView as a child view of
the
parent
view bean, and to include the correct JSP content that
references
that child
view.
The included JSP content would now look something like this:
<jato:view name="MyHeaderView">
<table>
<tr><td>... <jato:staticText name="UserFirstName"/>
...</td></tr>
<tr><td>... <jato:staticText name="UserSSN"/> ...</td></tr>
</table>
</jato:view>
If we now included this content in the parent JSP from furtherabove, we get
the following as the JSP content before it is translated into aservlet:
<jsp:useBean id="viewBean" class="..."scope="request"></jsp:useBean>
<jato:useViewBean className="..." fireChildDisplayEvents="true">
<jato:view name="MyHeaderView">
<table>
<tr><td>... <jato:staticText name="UserFirstName"/>
...</td></tr>
<tr><td>... <jato:staticText name="UserSSN"/> ...</td></tr>
</table>
</jato:view>
</jato:useViewBean>
Ultimately, this technique is called "view compostion" or "view
aggregation", and is one of the major new features of JATO. Youcan now
define reusable view components and embed them in multiple viewcontainers,
on the same page or on different pages. Each page acts as a
frame,
in which
you provide the contents from modular components. Using thistechnique, you
can develop reusable view classes and chunks of JSP that can bearbitrarily
combined into complex pages.
I know this is a long and rambling discussion, but I hope I've
made
myself
at least partly clear. I'm more than happy to clarify anything
or
elaborate
more. Please let me know.

How to get the values of an Array using JSP Tags

Hey guys,
I need some help. I've splited a String using
fn:split(String, delim) where String = "1,2,3,4" and delim is ,
This method returns an Array of splited Strings. how do i get the values from this array using jsp tags. I don't wanna put java code to achive that.
Any help would be highly appreciated
Thanks

The JSTL forEach tag.
In fact if all you want to do is iterate over the comma separated list, the forEach tag supports that without having to use the split function.
<c:set var="list" value="1,2,3,4"/>
<c:forEach var="num" items="${list}">
<c:out value="${num}"/>
</c:forEach>The c:forTokens method will let you do this with delimiters other than a comma, but the forEach tag works well just with the comma-delimited string.

It's strange bacause DTD is available under given address.

I can't get this script to work with the XML stype jsp tags. It keeps telling me the <jsp> tags are untermintaed. Is there a special trick to fix this or do I have to use the non-XML type tags?

Sorry, I didn't mean to put the extra " in the out.println text string. :-/

Create frames using JSP tags

I am trying to create two frames in my JSP page . However it just displays a blank page on execution.
I am using following code to create frames:
<hbj:content id="myContext" >
      <hbj:document>
     <hbj:documentHead>
     <frameset cols="100,*" border=1 frameborder="1">
                 <frame name="frame1"
                        src ="http://www.yahoo.com">
                 <frame name="frame2"
                        src= "http://www.google.com">
            </frameset>
     <hbj:documentHead>
    </hbj:document>
</hbj:content>
Thanks

Neeti,
   Just get rid of JSP tags and put the frameset html on jsp page. It should work without JSP tags.
<html>
<frameset cols="100,*" border=1 frameborder="1">
<frame name="frame1"
src ="http://www.yahoo.com">
<frame name="frame2"
src= "http://www.google.com">
</frameset>
</html>

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.

Problem with boolean attribute of JSP tag

Hi,
I've being trying to use a custom JSP tag, which has a boolean attribute, declared in the TLD as follows:
<attribute>
<name>checked</name>
<required>false</required>
<rtexprvalue>true</rtexprvalue>
<type>boolean</type>
</attribute>
The JSP code snippet is:
<ui:check checked="<%= myBean.isChecked() %>"/>
where myBean.isChecked() returns a boolean value (primitive type).
It works fine on some web containers, but it causes a JSP compilation error on Oracle9iAS 9.0.3 Java Edition, which looks like the following:
Method toBoolean(boolean) not found in class test. _jsp_taghandler_57.setChecked( OracleJspRuntime.toBooleanObject( toBoolean( myBean.isChecked())));
After decompiling the container's JSP parser, I found what I think it's a bug. The java class generated by the JSP parser does not define a toBoolean method, and neither do its superclasses. The method is defined on the OracleJspRuntime class! I think the correct code would have to be something like:
OracleJspRuntime.toBooleanObject(OracleJspRuntime.toBoolean(...))
If I'm correct, then the "convertExpression" method of the "oracle.jsp.parse.JspUtils" class must be changed, because it outputs such wrong code for not just boolean types, but for all the primitive types.
So, has anyone ever faced this problem before? Does it have a workaround, or a patch? Is it included on the bug fixes for the 9.0.4 release?
Thanks!

Instead of:
out.println("<body onload ="+strAlert+">");
Try this:
out.println("<body onload =\""+strAlert+\"">");
Add two \" around the alert call.

Jsp tag libraries

hi All,
I am receiving an error when i come to start a jsp page, it returns null pointer exception. so when I checked it is coming from the JSP tag Libraries. instead of the jsp libraries there is a null pointer exception . so any clue how to fix that ?
thanks
Amgad

Yes, marika, download the Jakarta JSTL implementation, unzip it, and put it everything in its /lib directory in your WEB-INF/lib. Then you can refer to the taglib in your JSPs like this:
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>That's all you need to do. No <taglib> in your web.xml or anything else. - MOD

JSP tags for managing MBeans??

Hi,
I'm trying to build a GUI for managing a custom MBean. The MBean implementation is a wrapper for a singleton class (specifically, a Configuration class for a web app). I've tried using WebJMX, but the problem there is that it relies heavily on MX4J, and has not kept up with JMX advances in the last two years (MX4J is a bit ahead of weblogic 8.1).
Just as there is a set of console extension jsp tags, I suspect that a set of JSP tags exists for the developers of the Weblogic console to write their JSP pages to manage the weblogic MBeans. I coud just try to figure out the pattern of the INPUT and FORM tags in the html, but that leaves me with a possibly-inaccurate, version-dependent, non-dynamically-generated page to manage one MBean.
Does such a set exist? Could someone point me to any information about how to use such a set of tags?
I would like to be able to have the JSP I use for my console extension display an interface for modifying MBean configurable fields and executing MBean operations. What would the best way be to do this? I do not want to embed the Sun JMX RI in my web-app and launch a separate HtmlAdaptor listening on a different port. I would like the admin to the MBean be accessible through (and only through) the weblogic console.
Thanks in advance for the help,
Matt Geis

Jsp tag for blog attribute in a flex asset

hi Experts,
I am using FW7.6.1, I have a flex asset with a blob attribute, when I create that flex asset, I can upload an image in that attribute, but I did not find a jsp tag for rendering that attribute which has a image saved, another question is what jsp tag should be used in case of a word file is uploaded in that attribute, that's to say:
1. for a image, I want to display it in browser.
2. for a word file, I want to show popup window to ask user if he wants to download or open.
By using assetset:getattributevalues and render:stream, it's just for string type of attribute, not for blog.
Thanks in advance.
Best regards

hi all,
I got the answer from dev guide, seems should use:
<blobservice:gettablename varname="uTabname"/>
<blobservice:getidcolumn varname="idColumn"/>
<blobservice:geturlcolumn varname="uColumn"/>
and render:satelliteblob
some complicated then I expected.
Best regards

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 Javascript attributes in a JSP-Tag

Hi!
I want to submit a Javascript attribute to an embedded jsp Tag:
<script language="JavaScript">
function test()
var jscriptvar= document.myform.myselection.selectedIndex;
result = <%= jspobj.doit(jscriptvar) %>;
</script>
The exception is : Undefined variable: jscriptvar
Is that possible?
It works, if the doit-method doesn't have a parameter.
I hope, someone can help me.
Thanks
Torsten

JavaScript is executed on the client-side by the browser. The JSP code is executed on the server-side by the server and has no knowledge of JavaScript variables. You can not mix them in this manner.
