Problems with parameterized custom tags - urgent
Hi All,
I am not able to retrieve my attribute values in Tag Support Class?
it doesn't give any errors while compiling and also the tag works without those attributes. I am able to print some html using the same tag but not able to print the passed attribute values?
any help is highly appreciated!
Thank You.....:-)
Thanks for the response!
Infact I figured it out and made it working but still it's a question to me.
Change I have made in my .tld file is making rtexprvalue to true - "<rtexprvalue>true</rtexprvalue>".
As per documentation it should matter but bcoz of this setting to false I was not able to retrieve.
Anyways Thanks again & Have a Good Day.....:-)

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 {
private String mColor = "red";
public void setColor(String aColor) {
mColor = aColor;
} // 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());
return EVAL_PAGE; // other return: SKIP_PAGE
} // doEndTag()
} // TagError

Rendering A JPEG image with a custom tag
Hi All,
I have dilema. I'm trying to rendering a jpeg in IE/FireFox with a custom tag that I developed. I'm able to access the bean and invoke the getter method to return the InputStream property. But what gets rendered is the byte code not the image. I've tried just about anything I could think off. If any body has an answer I would difinitely appreciate it.
Thanks,
Tony

**************************************************************************************If you have access to an image editing tool such as photoshop, I would advice you import the image into Phototshop and save it in a different format e.g, GIF format and re-import it into Final Cut Express HD. This could solve your rendering problem if all you need is to use a Still image.

How to call a method repeatedly with JSP custom tag?
This senerio is very similar to the usage of StringBuffer.
I have a problem which can be solved easily with scriptlets:
<% NameValuePair nvp = new NameValuePair(request.getQueryString()); %>
<a href="foo.html?<%=nvp.add(name1", "value1").add("name2", "value2").toString();%">">Foo</a>
<a href="bar.html?<%=new NameValuePair(request.getQueryString()).add("x", 1).add("y", 2).toString()%>">Bar</a>
But I cannot use scriplets because it's turned off. I can only use jsp custom tag / jstl. How would I implement this functionality with a custom tag? How would the JSP code look like? Our container supports JSP 2.0.
Thanks.</a>hi,
you can do within 2 step-
1) use <%@page import="your_java_class"%>
2)use scriptlet code <%...%> and write coding in this tag.
means create instance of your java class .
<% your_java_class obj1=new your_java_class();
obj1.method_of_your_java_class();
%>or
3) you can make javabean to use method of java class.[Best option]
Thanx

Problem with InputSelect Data Tag if there is no register in database
Hello all,
I4m working with Oracle JDeveloper 3.2.2 and I have a problem with InputSelect Data Tag.
When I tried to access a JSP page with this object and there was n't a record at the table, an error occurred.All the input tags operate on rows in the cache. Prior to using the input tags, use the Row tag with the 'Create' option to make sure you have a valid row.

4.1.1 SDK Problems with missing xpacket tags in sidecar XMP files
The current 4.1.1 SDK has problems with sidecar XMP files that don't have the xpacket headers and trailers, i.e:
<?xpacket begin='' id='W5M0MpCehiHzreSzNTczkc9d'?>
<?xpacket end='w'?>
is missing. Now, unfortunately Adobe Bridge CS2/CS3 does not export these xpackets in sidecar XMP files.
The standard, http://www.aiim.org/documents/standards/xmpspecification.pdf, is also very vague about it all:
● Write external metadata as though it were embedded and then had the XMP Packets
extracted and catenated by a postprocessor.
The grammar is strange(past tense had) and the spec implies that the xpacket should be extracted and again catenated... Someone should review this document and clearly state if xpacket statements should be in sidecar files or not. I suspect myself that they should be there, but the standard is very vague.
Anyway, there are two places in the SDK code where changes might be needed:
XMPFiles::Initialize has XMP_Asserts in case the xpacket header/trailer is missing, but the underlying assert is only active in debug builds.
XMPScanner::PacketMachine::FindNextPacket () also has in its truth table the assumption that the xpackets exist.
There could be even other places in the code that assumes that the xpacket tags are present in all files, which includes text XMP sidecar files.
Anyway.
a) Shouldn't bridge export the xpacket tags? Same with any other application?
b) If the spec is vague, then the SDK should not assume that the xpacket tags are present.
Any comments? Has someone already fixed this issue as I suspect a lot of apps using the the XMP SDK would break concerning reading XMP sidecar files? Thx, KentI was able to work around the problem by creating a mapped view of the .xmp file (this creates an array in memory backed by the file on disk, so there's no need to read the file into a separate internal buffer), and constructing the SXMPMeta object directly from the buffer. (The ctor for that class calls ParseFromBuffer, so this is the same thing as was suggested by other messages in this thread.)
It seems that Adobe needs to do one of these things:
(1) say that Bridge CS3 has a bug, and agree that Bridge CS3 should include a proper xpacket header when writing xmp sidecar files
(2) say that the XMP Toolkit has a bug, and that the SDK should be able to parse sidecar files without an xpacket header, and agree to fix the toolkit
(3) say that Bridge CS3 and the XMP Toolkit behave as expected, but then provide a sequence of steps by which users of the XMP Toolkit are expected to read xmp sidecar files written by Bridge CS3
Does Bridge CS4 write an xpacket header to the xmp sidecar files?
Maybe what I could do is create a custom file handler for .xmp sidecar files, so I could use the SXMPFiles for everything, instead of having to special-case .xmp files.
My needs are pretty modest though, and it might be just as simple to use the MS DOM-based XML parser for load the xmp sidecar file. I bet I could get the data I need (only the "Rating" for now) using a simple XPath expression.

Problem with parameterized reports in InfoView interface with Russian local
Please, help!
We have a problem with users, who have u201CRussianu201D as Info View portal interface language. Users have problems with reports which are parameterized. When user tries to select a custom date he gets prompt with incorrect template "Enter Date Report: - jj.nn.aaaa H:mm:ss". As a result the report is not updated. If User uses English interface all is OK.Maksim,
Could you provide the following info:
1) BOE XIR2 or BOE XI3.1?
2) Which Patch-level?
3) Are you using the JAVA infoview or .NET infoview?
4) Which kinds of reports are you attempting to put the custom date range in (CR, Webi, Deski)
Thanks!

[JS CS3] Problem with iterating xml tags
Hello,
Below is a script that is supposed to find text in a document and then tag it with an xml tag. I have run into a problem, which if I solve in the way I know how, causes another problem.
When I iterate in a positive direction--i++--the first instance of the text (in this example "abc") is correctly tagged. But the second instance the tag recedes by two characters, that is, tags the three characters prior to the "c." A third instance will recede two more characters, ad nauseam, if my Latin is correct.
The solution is to iterate backwards, i.e., i--. But this causes another problem. If there is more than one story, then the xml structure reverses the order of the stories. The elements within a story are ordered correctly however.
So why is this happening and how can I solve it?
Thanks,
Tom
var myDoc = app.activeDocument;
var findABC = theTextFinder(myDoc,"abc");
xmlTagIt(myDoc,"abc",UIColors.RED,findABC);
//*****functions*******
function xmlTagIt(docRef, tagName,colorOfTag, arrToTag){
var tagName, colorOfTag, arrToTag;
myDoc.xmlViewPreferences.showStructure = true;
myDoc.xmlViewPreferences.showTaggedFrames =true;
myDoc.xmlViewPreferences.showTagMarkers = true;
myDoc.xmlViewPreferences.showTextSnippets =false;
myDoc.xmlPreferences.defaultStoryTagColor = UIColors.WHITE;
var rootElement = myDoc.xmlElements.item(0);
if (myDoc.xmlTags.item(tagName) == null) {
var tagRef = myDoc.xmlTags.add(tagName, colorOfTag);
} else {//if tag already exists then stop the script. Avoid double tagging
myDoc.xmlViewPreferences.showStructure = true;
alert("You have already run this script.");
exit();
}//end else
//for (var i = arrToTag.length-1; 0 <= i; i--){
for (var i = 0; i <= arrToTag.length-1; i++){
var elementRef = rootElement.xmlElements.add (tagRef,arrToTag[i]);
}//end for i
}//end function xmlTagIt
function theTextFinder(docRef,textFindIt){//last argument is the string of text to find
app.findTextPreferences = NothingEnum.NOTHING;
app.changeTextPreferences = NothingEnum.NOTHING;
app.findTextPreferences.findWhat = textFindIt;
var arrTextFindIt = myDoc.findText();
return arrTextFindIt;
}//end theTextFinderDave,
Thanks for the reply.
I'm not sure what you mean by "convert the references on the fly." You mean find a way to advance two characters forward and tag that? In the script I submitted here I am only searching for "abc," which of course I would not search or at all in real life. The script uses grep to search for about twenty different typographical errors that typically appear and tags them all.
Reiterating backwards seems, at first sight the way to go. But I haven't a clue as to how to reverse the order of the stories. I can get an array of stories, and array.reverse() them, but am not sure how to then make the script put this reversed order into the xml structure. Any hints?
There, of course is bigger problem with the stories. If the document is written with one story created after another then the order of them is top to botom. But if say a text frame edited into the middle of all this, that story is still the last one in the xml structure. At least in one test, that was so. Maybe the way to solve this is to build an array of stories that have as one xml attribute the page it first appears on. Then order the array according to that attribute.
Any advice you give will be appreciated.
Thanks,

Hi
i want to make a custom tag encapsulating certain functionalities of existing tags in one tag namely tomahawk dataPanel and html facets.
Where can I get the source for html jsf tags so that I can look into it and modify.
ThanksOriginally posted by: mbuc.edp-progetti.it
Would you like to know a fine workaround?
If you have in your jsps a reference to the tld like this:
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
make a C:\WEB-INF\ directory on your PC and copy in there your tlds
(C:\WEB-INF\struts-html.tld). The same for linux: /WEB-INF/struts-html.tld.
So you do not have to change anything in web.xml nor in the jsp pages!
Bye,
Marco.

Problem with logic:equal tag when used with bean:write
Hi All,
I have a problem with logic:equal.When i tried to use the following piece of code its not working
<logic:equal name="var in session" value="<bean:write name='var in request'/>">
Do some thing
</logic:equal>
its not working i know we cant use nested tags
is thr any alternative instead of using a scripletA scriptlet expression is about all you can do.
<bean:define id="tempVar" name="var in request"/>
<logic:equal name="var in session" value="<%= tempVar %>">
...If you have a JSP2.0 container with EL enabled, then you could use an EL expression instead of the standard <%= expr %> -
Recursive & Loadable WD-Tree-Tutorial: Problems with parameters; NullPointe
Hello all, it's me again
This time I have a problem with the Tutorial called "Constructing a Recursive and Loadable WD-Tree". I followed each step in detail, but when I deploy it all I see several errors/mistakes in my resulting App:
1. I can click on the "directories" in this example and the directory-text is displayed in the InputForm. Normally it should only display "filenames", not directory-names... I checked the bool-properties in the addChildren-method and they are set as it's said in the tut.
2. When I try to expand any of the two nodes (C or Games; D is already expanded and includes "Games") I get a NullPointerException for the addChildren()-method in the first line (parent.nodeChildNode();). So the parameter "parent" is null or does at least not contain what it's expected to.
3. I have some Warnings: "TreeNodeType 'onAction.onAction': Parameters of action 'Select' and event 'onAction' are not compatible" and the same again for the second action (LoadChildren). So perhaps problem 2 can be solved by solving no 3?!
I'm stuck. Can anyone help me please?
I doublechecked that everything is as said in the tutorial.
Regards
MichaelHi
I realized I had an "Warning"-Message at my View-Context-Root-Node, where it said "Migrate Context". After I did this I get an "internal server error", Failed to process request.
Hmm, it seems as if there were a lot of changes from NW2004 to NW7.1, cause when I try to deploy the ready-to-deploy-tutorial (downloadable along with the Initial project template from SDN) I get deployment errors.
So I'll stop it now or perhaps try my own implementation (with java.io.File and recursive methods and loadable tree) to get familiar with the tree-thing in WD/Java
Thanks so far for the help, it's greatly appreciated.

Problem with email being tagged as spam
We recently changed our ISP, and up to this point we had no problems with emails to partners being tagged as spam. I've setup the send and receive connectors as the public FQDN, but we're seeing the following NDR:
p01c12m113.mxlogic.net #554 Denied[CS] [50e56f35.0.4929.00-2377.9578.p01c12m113.mxlogic.net]
(Mode: normal) ##
I've emailed McAfee to see what the problem is, but I haven't heard back. When I do a query on their web site, the web interface doesn't indicate there is a problem with this mail server, but it's continued to reject messages today. Even though the send
and receive connectors are set to mail.domain.com, but there still a portion of the header with the domain.local. I'm wondering if that might be causing a problem. Can anyone help me out here? Thank you.

<o:p></o:p>ok lets start one by one.. to rule out the problem with your Email system go to www.testexchangeconnectivity.com and perform the exchange tests like inbound/ outbound and other relevant tests and share the results. once this is confirmed then come to Mcafee
Let me know which Exchange and which Mcafee versions you are using as i also have Mcafee and it needs some tuning. May be i can help you. but need to know the info and if you can paste a NDR which are tagged as SPAM
MARK AS USEFUL/ANSWER IF IT DID
