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.

XML to ABAP Problems with many attributes in one Tag (Simple Transform)

Hi
i have a XML-Dataset like this. (It's a sample, in originl there are more fields under <Faktura> and more <Faktura>.) My Problem is reading the Attributes.
<?xml version="1.0" encoding="utf-8"?>
<Fakturen>
<Faktura AVnr="123456789" Amt="100" Lang="1" Nr="1209" RechnungsTyp="B" Status="7" Waehrung="CHF" Year="2011" ZahlungsTyp="B"/>
</Faktura>
</Fakturen>
In the Tag "Faktura are many Attributes. How can i read this. I have try this with this code and many other variation. But it does not work.

Hi
Thank you for your answer. The function module SMUM_XML_PARSE is a good way to Read a XML. Now I have found the Correct way with simple transfer and it works with an array too.

please help me out. below is the code:
public class TestApplet extends HttpServlet

Problem with optional attribute caching on a custom tag

Hello,
I've created a tag by extending TagSupport. I have one attribute that is optional. I'm having a problem with this attribute since the tag is cached. If the value is not specified in the tag, it is always using the previous value from the past request.
I understand why this is happening, but I wonder if there is anyway to reset this value besides doing it at the end of the doStartTag or in the doEndTag methods? I simply want it to be an empty string if it is not in the request.
Thanks,
Tim

Thats abit overkill in my opinion.Probably yes, but its a cleaner option. In case your doEndTag handles custom exceptions, you would anyhow need to put this code in a finally block, right ?
public int doEndTag() throws JspException {
try {
call some methods that throws other checked exceptions;
}catch(Exception1 e){
throw JspException(e);
}catch(Exception2 e){
//log and ignore
}finally{
//clean up here
return an int;
Having said that, different containers implement the spec a bit differently. For example, in our project, we use weblogic and for wl, we put our clean up code in the release() method which according to the spec, needs to be called only before gc. Weblogic implementation is a bit different - its called after doEnd() for every use of the tag.
This is from jsp spec regarding tag life cycle especially with reuse
Some setters may be called again before a tag handler is reused. For
instance, setParent() is called if it�s reused within the same page but at a dif-ferent
level, setPageContext() is called if it�s used in another page, and
attribute setters are called if the values differ or are expressed as request-time
attribute values.
�Check the TryCatchFinally interface for additional details related to exception handling and resource management.

Very urgent : Problem with field attributes in Datasource

Hi
I am getting a problem with field attributes in the datasource.
The issue came up after i modified the extract structure-i modified one field and
added one field to the structure.Now those two fields are not visible in BW.
When i checked with transaction rsa2, i could find that for those two fields , the
field attribute is <b>'A'</b> which is <b>'Field in OLTP and BW Hidden by SAP'</b>.
I tried to modify the field attribute to make it visible.Now the issue is that it is not getting reflected after transport in the Q system.What can be the issue.In the Q system its still the old value 'A' ,which makes the fields invisible.
Please let me know what can be the issue.
Regards
Leon

Hi,
did you change this attribute via RSA2?
you need to change your datasource via postprocessing (RSA6); then transport your DS to your Q source system.
Replicate your datasources in your BW.
Finally modifiy your Transfer Structure by editing your TRules ( tab Datasource/Tran structure), move your new fields from the right frame to the left frame)
Maintain your TRules
Activate
hope this helps...

JSPs using Custom Tag with Boolean attribute cannot compile

Hi,
In Oracle9iAS(9.0.3), a jsp using a tag extension, which has a Boolean attribute, caused the following compile error, although the jsp is valid in other web containers.
ERROR:
/opt/oracle/j2ee/home/application-deployments/simple/simple/persistence/_pages/_test.java:56: Method toBoolean(java.lang.Boolean) not found in class _test.
__jsp_taghandler_1.setExists( OracleJspRuntime.toBooleanObject( toBoolean( b)));
JSP:
<%@ page language="java" %>
<%@ page errorPage="error.jsp" %>
<%@ taglib prefix="jnpr" uri="/WEB-INF/testtag.tld" %>
<%
Boolean b = Boolean.valueOf("true");
%>
<jnpr:TestTag exists="<%= b%>"/>
The boolean value is <%= b %>
Tag Handler:
package defaultpak;
import javax.servlet.jsp.tagext.*;
import javax.servlet.jsp.*;
public class TestTag extends TagSupport{
private Boolean exists = null;
private java.lang.Boolean getExists() {
return exists;
public void setExists(java.lang.Boolean newExists) {
exists = newExists;
public int doStartTag() throws JspException {
return super.doStartTag();
Is this a known problem? Is there a way to get around this?
Thanks in advance.
Fred

This is a known issue with 903, fixed in coming 904.
In 903 the workaround is to use primitive type "boolean" instead of Object type "java.lang.Boolean" in user's getter and setter code for the taglib.

Custom Tag with boolean Attribute problems

Hi,
I've created a simple custom tag that is expecting a boolean attribute called "disabled". In my Tag derived class I've created a setDisabled(boolean b) method and set the following in the tag descriptor:
<attribute>
     <name>disabled</name>
     <required>false</required>
     <rtexprvalue>true</rtexprvalue>
</attribute>I'm using a JSTL expression "${someExpression}" which, when I do a c:out on the value, returns true.
I call the tag like this:
<mytag disabled="${someExpression}"/>However, in my custom tag class the value is passed as false. I can get true passed in if I hard code it, but that isn't going to work.
I've tried a number of different combinations and even read through this forum for the last 2 hours and cannot seem to figure it out.
What am I doing wrong?
Thanks,
John

TLD File, per your previous recommendation:
<attribute>
     <name>disabled</name>
     <required>false</required>
     <rtexprvalue>true</rtexprvalue>
     <type>boolean</type>
</attribute>My Tag class (snippet):
public class ButtonTag extends TagSupport
private boolean disabled;
public ButtonTag() {}
public boolean isDisabled()
     return disabled;
public void setDisabled(boolean b)
    disabled = b;
}A sample of the jsp file invoking it:
<c:set var="result" value="${computedValue}"/>
<ltm:button disabled="${result}"/>Regardless of the value of result, ("true" or "false") it always passes false to the setDisabled method of the button tag class.

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.

XSLT-problem with sequence attributes

Hi,
in my XSLT-program (i'm a real newbie!) i'm adding dynamically attributes and their values to a tag, by using the following code :
<SUPPLIER>
<xsl:attribute name="FUNLOC">
    <xsl:value-of select="SUPPLIER_FUNLOC" />
</xsl:attribute>
<xsl:attribute name="NAME">
    <xsl:value-of select="SUPPLIER_NAME" />
</xsl:attribute>
<xsl:attribute name="LOCATION">
    <xsl:value-of select="SUPPLIER_LOCATION" />
</xsl:attribute>
</SUPPLIER>
The problem is that the attributes in the resulting xml-file are alphabetically ordered. For instance :
<SUPPLIER FUNLOC="9522222" LOCATION="NL" NAME="Test vendor VMOI">
How can i arrange that the result of the xml-file is a sequence of entrance is taken, so
<SUPPLIER FUNLOC="9522222" NAME="Test vendor VMOI" LOCATION="NL" >
regards,
Hans

Hi Hans,
I think you're using ABAP-XSLT?!
If you do so, you can solve the sorting problem by using a 1:1 Message mapping after the ABAP-XSLT mapping. This resolves the problem that the nodes are not in the correct order.
In your interface mapping you have to configure 2 mappings:
1: ABAP-XSLT
2: Message mapping.
Of course this means that the total processing time increases a little bit.
I had the same problem with the sequence of my (ACC_DOCUMENT) idoc nodes, the ABAP-XSLT screwed up the idoc, but the 1:1 message mapping solved the problem.

Mark

Problem with the method in JSP

<%@ method = "doPost" %> ******* if i remove this statement i am getting output but what is wrong with this statement ********
<HTML>
<HEAD><TITLE>Hello</TITLE></HEAD>
<BODY>
<H1>
<% if (request.getParameter("name") == null) { %>
Hello World
<% } else { %>
Hello, <%= request.getParameter("name") %>
<% } %>
</H1>
</BODY></HTML>
(thank you for the last posted problem solving)

There is no <%@ method %> tag for a JSP.
http://java.sun.com/products/jsp/syntax/1.2/syntaxref12.html
It looks like you are trying to write a JSP that only accepts post requests - not get?
I'm not sure if you can accomplish that in a JSP directly.
You can with an HttpServlet (which is where the doGet/doPost methods are defined) but HttpJspPage doesn't extend that class necessarily.
Best you could probably do is put in a test of request.getMethod() to see if it is get/post.

balu i have tried by seeing u r blog.
this is my structure of tables
plexes (if i iterate plexes table gives plex object)

will come from
i tried in this command action with HTMLDataTable getRowData()
i am not getting the selected row data .i am downcasting this getRowData() to plex.

          You realy can do it like Xiang says, but the better way is to use packages. That's
          the way BEA is designed for. If you use packages you can but your bean classes
          in every subfolder beneath Classes. Here for example we have the subfolders test
          and beans:
          You have to declare the package on top of your Bean Source Code:
          package test.beans;
          In your JSP you don't need the import code of Xiang. You only have to refer the
          path of your bean class:
          <jsp:useBean id="testBean" scope="session" class="test.beans.TestBean" />
          There are some other AppServers that only can deploy Java Beans in packages. So
          if you use packages you are always on the right side.

Problem with rendered attribute in jhs 10.1.3.3

We are currently trying to migrate our applications from jhs 10.1.3.2.52 to jhs 10.1.3.3.87 using jdeveloper 10.1.3.5. We are facing a problem with all the detail groups structured inside detail group regions - they have all disappear from the pages.
In my example code i have two master-detail groups Products (Master) and ExpertiseAreas (Detail) on the same page:
Products - Group
-> ExpertiseAreasDtl - Detail Group Region
-> ExpertiseAreas - Group (Samepage="true")
The problem is that the detail group ExpertiseAreas is not rendered on the page.
As i looked in through the pages generated by the 2 different releases of jhs using the same app definition, i can see the following:
CODE GENERATED FOR THE ExpertiseAreasDtl Detail Group Region (all the vms used are the default):
in jhs10.1.3.3.87:
<af:panelGroup *rendered="#{(ProductsIterator.currentRow!=null and ProductsIterator.findMode!='true')}"* id="ProductsRegionsExpertiseAreasDtlPanelGroup">
in *jhs 10.1.3.2. 52*:
<af:panelGroup id="ProductsRegionsExpertiseAreasDtlPanelGroup">
First of all a rendered attribute is being generated in the new version of jhs and not in the old.
The real problem seems to be with the iterator binding generated from verticalRegionContainer.vm in the regular expression: "#{(ProductsIterator.currentRow!=null and ProductsIterator.findMode!='true')}". It should have been *bindings.*ProductsIterator and not plain ProductsIterator. Has anybody got any ideas on how to solve the problem?
Thanks
Giorgos

Giorgos,
We have uploaded a new service update, 10.1.3.3.88, on the cso.oracle.com site. This should fix your issue.

Problem with keeping attributes updated

We have a problem with the server model in Designer.
We have made a E/R diagram and genereted it to a server model diagram. Afterwards we want to delete some attributes which we delete back in the E/R program. Then we make some new attributes instead and generate a new server model diagram but the attributes which we have deleted in the E/R diagram is still present in the new server model diagram. The new attributes are there too. It is like the server model diagram only updates the new attributes, but doesn't delete the old, wrong, attributes.
What can we do to solve the problem?

Hi,
DDT will modify the attributes values (datatype, size etc.) on the target tables.
DDT doesn't drop the column if its corresponding attribute is deleted in ERD.
However we can achieve this by deleting the table definition from DE and then executing the DDT on the new/modified Entity.

Wilson.
