Sp9 / pre-release / problem with jsp tags
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.

The class does contain the setter, so we don't know why the message pops
up. After rebooting the server, the page works properly (!) Does anyone
know how to get rid of it ? We're running out of ideas, and rebooting
the server every 2-3 days is not acceptable.
The configuration consists of BEA WebLogic 5.1.0 SP8 + JDK 1.2.2_07 +
HPUX 11.0.
Any help is greatly appreciated.
Jacek Laskowski
so doesn you bean have a
void setLimit(String) {}
String getLimit() {}
or does it have mismatched getter and setter?
like
setLimit(String) {}
int getLimit() {}
take a look at :

Problem with display tags (not accepting inner tags)
Hi guys ,
I am using display tags which is fine but i had a problem with anchor tag and the jsp display tag.
<display:column title="Row_Id" >
' target="-blank" onclick=""><c:out value="${row_rowNum}"/>
</display:column>
here i got the exception:
The value of attribute "href" associated with an element type "a" must not contain the '<' character.
here if jstl is not used then how to put my value in anchor tag
please help me.Can you use EL directly:
<a href="example.jsp?id=${row.id"/"></a> -
XSLT problem with img tag in Saxon
Hi,
Iam getting a problem with <img> tag when transforming a document using Saxon transformer. In the input XSLT I have proper closing tag for <img>, but the output of the transformation is not well formed as the closing tag for <img> does not appear. I need to feed the output to a FO object to generate a print preview, but the output is not well-formed.
Kindly help to resolve the issue.
Kind Regards,
AbhinandanPerhaps that is because you are generating HTML as your output? As I recall, <img> tags don't have to be closed in HTML. So try generating XML instead if you need XML.

Hi everybody,
We're using OC4J 9.0.2 but we have a problem with iterate tags. The doAfterBody is ignored and so, the body is never done !
This work fine with version 9.0.3. If we compare the two generated servlets(9.0.2 & 9.0.3), the code is really different.
Is this a know bug, is it possible to solve this problem ?
Our client is still in 9.0.2 and is not ready for an upgrade.
Any idea is welcome ...

BelgiumIt's unlikely anyone can help you if you don't show any of your code or explain what is really happening.
Have you set breakpoints (or added print statements) in your doStartTag, doEndTag, and doAfterBody methods, and verified the return values are what they should be? -
Initial problem with JSP Custom Tag devolopment
Hi ,
I have encountered a problem with my JSP application which utilizes a simple custom tag.
First I created followinng directories.
1. %TOMCAT_HOME%\webapps\testTags
2. %TOMCAT_HOME%\webapps\testTags\META-INF
3. %TOMCAT_HOME%\webapps\testTags\WEB-INF
4. %TOMCAT_HOME%\webapps\testTags\WEB-INF\tlds
5. %TOMCAT_HOME%\webapps\testTags\WEB-INF\classes
6. %TOMCAT_HOME%\webapps\testTags\WEB-INF\classes\com
7. %TOMCAT_HOME%\webapps\testTags\WEB-INF\classes\com\tek271
8. %TOMCAT_HOME%\webapps\testTags\WEB-INF\classes\com\tek271\testTags
I created the essential four files, that is named as follows.
1.TagError.java
2.web.xml
3.testTld.tld
4.testJsp.jsp
Then i put the files under these directories as given below
testJsp.jsp under %TOMCAT_HOME%\webapps\testTags.
web.xml under %TOMCAT_HOME%\webapps\testTags\WEB-INF
TagError.java under %TOMCAT_HOME%\webapps\testTags\WEB-INF\classes
TagError.class under %TOMCAT_HOME%\webapps\testTags\WEB-INF\classes\com\tek271\testTags
testTld.tld %TOMCAT_HOME%\webapps\testTags\WEB-INF\tlds
Here is the content inside the files.
1.TagError.java
package com.tek271.testTags;
import java.io.*;
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;
public class TagError extends TagSupport {

} // setColor
public int doStartTag() throws JspException {
try {
JspWriter out = pageContext.getOut();
out.print("<font color=\"");
out.print(mColor);
out.print("\"><b>Error: ");
} catch (IOException ex) {
throw new JspTagException(ex.getMessage());
return EVAL_BODY_INCLUDE; // other return: SKIP_BODY
} // doStartTag()
public int doEndTag() throws JspException {
try {
JspWriter out = pageContext.getOut();
out.println("</b></font><br>");
} catch (IOException ex) {
throw new JspTagException(ex.getMessage());

Vinod A.Dear patreck ,
It does not work.
I have replaced the line
<%@ taglib uri="/testTaglib" prefix="test" %>
with
<%@ taglib uri="WEB-INF/tlds/testTaglib" prefix="test" %>
but now it shows the error ,
description The server encountered an internal error (Internal Server Error) that prevented it from fulfilling this request.
exception

Apache/Jserv Config Problem with JSP
Problem: Any JSP that contains a bean reference is not being loaded correctly.
The first thing I did was to create a softlink from the ".../Apache/Apache/htdocs" directory to
the directory which contains my *.html and *.jsp files (as instructed in the httpd.conf file).
Then, I followed the instructions on page A-9 of "OracleJSP Developer's Guide and
Reference, Release 1.1.0.0.0". They instruct you to add a wrapper.classpath entry into
jserv.properties that points at your directory that contains the .class files for your bean
classes. I did this too.
I then attempted to load my JSP file from the browser URL entry line. If my JSP does not contain
a reference to a bean, then the page loads fine. If it contains a reference to a bean, then I
get the following message:
Request URI:/webdocs/vps/hellouser/hellouser.jsp
Exception:
oracle.jsp.parse.JspParseException: Line # 4, Error: Unable to find class for bean: myBean defined
by tag with class: hello.NameHandler
I cannot for the life of me get Apache to look in one directory for the .jsp file and another for
the .class file(s). Any suggestions would be greatly appreciated!
MORE BACKGROUND:
If it matters..... My first venture was servlets and I've managed to workt that just fine: I
successfully modified "jserv.conf" to add a mount point (ApJServMount) for my new servlet zone
which I have specified in "jserv.properties". I have also created an associated properties file
for my new servlet zone. I've tested this configuration and all works fine for servlets, just not
JSP.
Once again, thanks in advance for any help regarding a solution to this problem!!!

Unknown problem with JSP, JavaScript - Pls help
Hi Friends,
I am facing a strange problem. Explained it below. Kindly help me as it is really affecting my work. Thanks in advance.
I am working on building a web application using jsp, servlet, ejb. the IDE used is WSAD 5.1.2.
I have the below :
1 JSP - Input page - for user input entry
2. Java script1 - For all client side validations
Java script2 - For handling the data submission to servlet (as selected by user)
Javascript3 - Header & Menu Bar
3 Servlet - This actually retrieves the values from the hidden parameters, sets them in session and redirects the control back to the jsp.
Logic for one small iteration : Two drop downs are there. On selecting the first drop down the second drop down should be populated and the first drop down should display the user selected value.
1. When the user selects the first drop down onchange() event gets fired which calls a method in the javascript.
2. In the javascript I set the value of a hidden form field to the selected combo index and submit the form to the servlet
3. In the servlet, I retrieve the hidden request parameter (Index),
set the index in session. Do my business logic based on the value of the index. Set the collection (to be displayed) in second drop down in session.
4. Send the response back to the JSP.
5. In the JSP, we have a method which is called during the onload() event of the body
6. This method sets the user selected values in appropriate controls(by taking from session)
Problem faced: I have a javascript which creates the menu bar for my application and this i've included it in my jsp. I dont know whats wrong with this javascript, when it is commented out the page works perfectly fine. Both the user selected value and the collection are loaded exactly as expected. But when it is included the collection is loaded in the second drop down but the selected index of the first drop down is not set - the drop down gets reset to the default value.
Also on body load of my jsp, I call a javascript method which sets the current date in one text field of my form. Even this is not working fine when I include this javascript. I don't see any script error in this javascript in my browser though. Strange but guess something basic :(
I'm sure there is nothing to do with session. I've tried printing the entire flow. The Servlet sets the values correctly in session and they are also correctly available in the JSP page. The JSP also gets loaded with the user selected values but something happens on page load which clears the values to default.
Am also confused in what way javascript is related to this, coz when I remove it things are working fine.
Am really helpless here pls do the needful. any help is appreciated.

Loading release drop down with the value matching with the entered issue date.
Scenario : User enters the issue date and the corresponding release number is
selected in drop down.
Logic 1:
1. Pass the issue date entered by user and get the matching release numbers
from EJB
2. Compare this with the combo collection and get the perfect match.
3. If more than one match is found take the one with amendment by default
4. Else get the matching one
5. Update the selected index of dropdown to this value

JDeveloper 9i - Problem with using tag lib
I am having problem with building my project, using JDeveloper 9i.
My project includes custom tag libraries.
When I build my project, I get back the following error:
Error(1): oracle.xml.parser.v2.XMLParseException: Invalid element 'servlet' in content of 'web-app', expected elements '[error-page, taglib, resource-ref, security-constraint, login-config, security-role, env-entry, ejb-ref]'
for every jsp file that has the taglib directive as follows:
<%@ taglib prefix="srp" uri="/srpTagLib" %>
Please note that the application runs OK, but it can not be build by JDeveloper for debugging purpose.
Any ideas? Please help!!!!
Thanks,
CathyWhat version is your tag library and what version is your deployment descriptor?

Hi all,
I am having a prolbem running the 'quote' JSP extension example that ships
with WLS 5.1. I'm running 5.1, with service pack 3 (although the problem
occurs with or without the sp), on NT.
It seems to find the taglib, but it is saying that the taglib isn't valid.
Could there be something wrong with the DOCTYPE that the example ships with?
It looks like:
<!DOCTYPE taglib
PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1//EN"
"http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd>
This also happens with the 'session' example, so I'm guess that I'm doing
something wrong, but I'm really not sure what that is.
If anyone has any ideas what I'm missing here, it would be appreciated.
Thanks.
Here is the exception I'm getting:
java.io.IOException: cannot resolve '/weblogic/taglib/quote' into a valid

I just figured this out by looking at console.war. If your web.xml says
<taglib-uri>blah.jar</taglib-uri>
<taglib-location>WEB-INF/blah.tld</taglib-location>
try
<%@ taglib uri="blah.tld" prefix="blah" @>
Note ".tld" at the URI. This must be an error.

Hi,
I am developing enterprise application using jboss portlets, ejb, jsp, jstl, other stuff on jboss AS.
I am facing some interesting problem in a jsp page which uses jstl. I have configured all jsp configurations with my web application.
Presently i am putting an endpage, current page integer values in a session.
In JSP page whenever i want to iterate a loop and some checks on endPage, curPage it gives me NumberFormatException and finally it results to compile the jsp page.
The error comes when i am using these variables from session with JSTL tags. The snippet where the problem seems to be is as :
<c:forEach var="selection" begin="1" end="${endPage}">
<c:if test="${selection == curPage}">
May anyone help me on this or whether the there may be some problems with the JSTL configurations ?
In my view JSTL configurations is ok but the problems seems to be in the statements above or there may be some other way to define it.
Any inputs ?

I have written a custom tag that I am having problems with. It works on some machines, but not on others. I have a page that uses many 'standard' tags. I have correctly set the URI etc, because all of my other tags work. However, on some machines, my custom tag gives me an error:
attribute does not support request time values
I'm assuming that I have the correct versions of standard.jar etc because all of the regular jstl 1.1 tags work. It is just my custom tag that throws an error.
here is the .tld for my tag:
<?xml version="1.0" encoding="ISO-8859-1" ?>

<description>Pass in the list of Breadcrumbs containing the actual information
about what tags need to be rendered on the page.</description>
</attribute>
</tag>
</taglib>
Any thoughts/help greatly appreciated...I encountered the same problem in our environment. I did the same thing as
James. Simply re-initialize all variables in the do end tag.
Also, with the nested tags you use you may also need to implement cloneable
in the inner tag if the outer tag keeps references to all the inner tag
instances.
For instance if the outer tag kept a vector of references to the inner tag,
then you would need to use clone() on the inner tag before adding it to the
vector.

Hi everybody,
In my JSP page called addUser.jsp, i have the different Struts Tag

</html:form>
I have of course the ApplicationResources.properties file with differents Struts properties:
errors.footer=</ul><hr>
errors.header=<h3><font color="red">Validation Error</font></h3>You must correct the following error(s) before proceeding:<ul>
errors.ioException=I/O exception rendering error messages: {0}
and an other one:
error.fieldsNeeded=<font color="#FF0000">Some fields are missing.</font>
when I call the addUser form, my JSP page display:
null Some fields are missing. null
Have u any suggestion about my prob?
tx a lot
s.Hi,
can u post the java code where u are actually adding the error to the action errors. may be there is something wrong with that. I dont see any problem with the jsp or the applicationsResources.properties.
Thanks

Experiences developing iViews with JSP tags
Hi,
has anyone experiences in the development of iViews using JSPs and the JSP tags ? Especially the useBean tag... I think it should be no problem to store beans in the session. If I want to share the bean among iView is it enought to synchronized each method of the bean ?
ThanksHi O.,
please, before going on guessing around what synchronization means, read some tutorial, that's what the link was thaught for. It is no problem at all not to know this topic, it's definitely some more advanced topic within the language, but it doesn't help if you don't know it to guess how it <i>could</i> work/behave.
> if I declare all getters and setters of the bean with
> synchronize I avoid the issue of inconsistent data
Once again: For pure getters and setters this sentence is definitely wrong. As long as complex class members are not manipulated / accessed concurrently, there is no need for synchronization (within the class).
> thread 1 sets a value a concurrent thread 2
> could read the data and would get a not actual value...
> if I synchronize the get and set, thread 2 will be
> able to invoke the getter after thread 1 finished the
> setter.
Once again: You don't have it in your hands which thread comes first. And synchronizing a method only means that a thread calling this method will run through it as an atomic operation, no other thread will disturb. But getters and setters normally are atomic, you cannot reach more... If a thread calls two (synchronized) methods of the same object, between these two calls, "the race is open again...".
A good example is http://www-106.ibm.com/developerworks/java/library/j-threads1.html
See the example at the end of this link, that's somehow just what we are talking about. The solution would be to synchronize the <i>setFoo(getFoo() + 1)</i> itself (for example with the bean object as locker). Whereas the synchronization of the methods is superfluous (and time consuming).
Hope it helps
