Escape : in url

I want to pass a : in a URL for a date item. Standard time is hh24:mi and I want to pass this to a calendar. Is there an escape character I can use please?

Plip,
You have to use a different character when you generate the link (pick any character that cannot appear in your actual data) then replace that character with a colon using a before-header process or something like it on the receiving page.

Disable auto escape in URL

I am trying to find a way to prevent auto escape in the URL calling the FMB.
eg. the URL string has 'http.....&otherparams=useSDI=yes+p_ename=smith'
in the browser it gets escaped as:
'http.....&otherparams=useSDI%3Dyes%2Bp_ename%3Dsmith'
I would like prevent the URL from being auto escaped, any ideas?
thanks in advance.

Thanks Jan,
I tried your suggestion but no luck. It seems like the charaters in the URL gets auto escaped by the html. I am trying to use the "POST" method to invoke the FMB, so that the credentials remain hidden. But, the non-alphanumeric characters in the otherparams gets escaped and the form doesn't seem to work properly.
<html>
<body onload=SubmitForms('user/pwd@db','john','smith') >
<form name="hidden_form" method="post" action="http://domain:port/forms90/f90servlet?">
     <input type="hidden" name="config" value="my_config">
     <input type="hidden" name="width" value="650">
     <input type="hidden" name="height" value="550">
     <input type="hidden" name="separateframe" value="false">
     <input type="hidden" name="form" value="emp.fmx">
     <input type="hidden" name="userid" value="">
     <input type="hidden" name="otherparams" value="">
</body>
<script>
function SubmitForms(con_str,p1,p2){
str1 = "fname="+p1;
     str2 = "+lname="+p2;
     document.hidden_form.userid.value=con_str

Url Not Escaped in Podcast Content

I am using ITunes v. 6.0.1.3 on WinXp and when subscribing to a podcast you must manually escape the url if it contains a space. Also if the content URL contains spaces iTunes will not escape that URL either and will error out while trying to download content.
How can I submit an official bug report?
Try and subscribe to this podcast: http://channel9.msdn.com/rss.aspx?ForumID=34&Mode=0&sortby=0&sortorder=1&format= mp3
All the content except the very oldest podcasts will fail to download because most of the new content is using spaces in the url for the content.
Thanks,
Adam
... sorry for the cross post my op should have been to this forum first.

Hi
I have some workaround for you.
You can open the URL in the Portal Content Area.
1. you have to create a portal component project to create a par file.
use the below code in jsp:
<table>
<tr width="100%" height="100%">
<td width="70%" border="1"><div style="background-color: rgb(194, 220, 255);font-family: Tahoma; font-size: 12px; display: block;">
Please click <a href="http://google.com" target='_blank'> here </a>to open google..<BR>
<BR>
<BR>
</td>
<td width="30%"><div style="background-color: rgb(194, 220, 255);font-family: Tahoma; font-size: 12px; display: block;"></td>
</div>
</tr>
</table>
2. export par to your portal from system admin -> support -> portal runtime - admin console
3. create a iview with the portal component.
4. change the iview properties to show in new window = false etc..
hope this will help

Problem with % signs in key value url parameter pairs

Hi,
Tomcat 5.5.9
Java Version 1.5
I'm having a little difficulty passing a certain key value pair via a URL to the processing component of my web application.
If I submit a value for lets say parameter 'product_name' and that value starts with a % sign then the value is passed to my processing component as 'null' if I remove the % sign the value is correctly received.
Anyone come accross this on a Tomcat server?
The data has to be tagged onto the URL rather than as a form 'Post', as it is used to create and populate a popup window.
Thanks in advance.

So the % is used in URLs to mark certain escape sequences, so when you put it in you value, it thinks that the value is actually an escape sequence, and probably translates poorly on the opposite side.
You will actually need to use the escape sequence for the % sign to get it work correctly. I don't recall the actual escape value, but:
If you use JSTL to put together the URL for you, you shouldn't have a problem, the values will be escapes:
<c:url var="popupAddress" url="http://www.mydomain.com/myapp/mupage.jsp">
<c:param name="product_name" value="%Whatever"/>
</c:url>
<script type="text/javascript">
document.open("<c:out value="${popupAddress}"/>","Popup");
</script>

How to send a list item value to URL to open data related to item value

Hi,
Iam using Apex4.0 and iam facing some problem. Iam unable to send selected list item value to the url specified in the HTMl region.
Here i want to open the data related to list item value in other page.
List item - :Familyp
i want to pass this selected value to the url and when ever user selected the list item and clicks on the url, then it should display the item value related data in new page.
I tried with &FamilyP in url but it's not working. Any one help me plz.
Regards
Vamsi.Tata

Is it a normal Select list or Multi Select list?
If you have select list that allows you to select multiple options then you cannot pass it through URL. Multi-select /Shuttle keep colon separated list in the item, and this confuses Apex because the Apex URL uses colons for a different purpose. No escaping or URL encoding will help.
If it is normal select list that allows selection of only one option then you can pass through the url. Unless of course the data has a colon in it.
For multi-select, and when the value contains colon, the only way is to save the value in session state, same page item or any other place like Application Item, and then reference it at the other end. Never pass through the URL.

Wsrp-requireRewrite for URLs in resource response ?

I'm using Portal 10.1.4 serving WSRP content from a
portlet producer running on 10.1.3.2 (JDev embedded OC4J).
I want to use an AJAX resource request to serve a fragment of
portlet markup containing further portlet and AJAX URLs.
URL rewriting for full page portlet rendering requests works fine,
but I can't get a resource request served with WSRP URL rewriting.
Here is my approach ... a resource request is sent from a portlet page
using a URL that was created in in a full portlet request.
The flag 'wsrp-requireRewrite=true' is WSRP encoded as '__ora_rewrite=1'.
The Portal server presumably intercepts the request and stores the value of this flag,
then sends the raw resource request to the resource servlet on the portlet producer
(i.e. markup generated through a servlet context, not a portlet context).
The new markup fragment contains URLs embedded between 'wsrp_rewrite' tags.
The Portal server should intercept the response and rewrite the URLs,
but it swallows the whole thing, and an empty response is returned to the client.
Is wsrp-requireRewrite=true supposed to work for resource requests ?
Any ideas what could be wrong ?
Mik

The problem was MIME type.
I had assumed Portal server would rewrite any text responses,
but it does not rewrite 'text/xml' data, in fact it sends it to the bit bucket !
So you need to force the response Content-Type in the resource provider.
The only valid rewritable types seem to be:
'text/plain', 'text/html' and variants like 'text/html+xml'.
The rewritten URLs will not be XML-escaped
i.e. '&' parameter separator will not be escaped to '&amp;' .
So when doing AJAX updates you have to explicitly escape the URLs
and invoke an XML parser in client-side JavaScript,
rather than relying on the implicit mechanisms within XmlHttpRequest.

Reverse the url-encoded process

Hi there,
Is it possible to flash rebuild a string that as been
url-encoded?
Thanks,

Hi David thanks for your reply.
It seems that my problem is not url-encoded.
I have a flash with a sendAndLoad vars to a coldfusion file.
The coldfusion is suppose to return a XML object. Instead it
returns a
String because the XML special characters [ <, >, " ]
are converted to
[<, >, "].
I think this problem is because you can have a programming
language based on
tags directly written in coldfusion (also a programming
language based on
tags). Like when you write html formatting text in an xml
structure. The xml
structure will assume tags like <br/> as a child Node
instead of a tag
content.
So I had to make some functions to replace special characters
in a string.
I don't agree with this solution, but it was the only thing I
came up with.
Thanks

Escape HTML for Page Title

Hi,
We created a custom TLN.
I would like to produce href tags but I face the problem of escaping HTML characters :
<aa on_click="return EPCM.doNavigate('<%= currNavNode.getName()%>',0,'','null',1,'<%= *StringEscapeUtils.escapeHtml(*currNavNode2.getTitle(userLocale))%>','')" href="#"><%=currNavNode2.getTitle(userLocale)%></aa>
The problem is that the org.apache.commons.lang.StringEscapeUtils is not available (or I do not know how to make it available...).
How do you proceed for escaping :
- HTML
- URL
- Javascript
Thanks in advance for your help.
Best regards,
Guillaume

Hi,
After many tries, I found out that simply quotes and double-quotes is enough for the Javascript EPCM.doNavigate to work (almost) properly.
Here is the code I use in the toplevelnavigation.jsp :
<% String titlePage    = "";
   String escTitlePage = "";
   titlePage    = currNavNode2.getTitle(userLocale);
   escTitlePage = titlePage;
   escTitlePage = escTitlePage.replaceAll("\'","\\\\\'");
   escTitlePage = escTitlePage.replaceAll("\"","\\\\\"");
   //escTitlePage = escTitlePage.replaceAll("\\&","\\&");
   //escTitlePage = escTitlePage.replaceAll("\\&","\\%26");
%>
<a <%=level2Id%> oncclick="return EPCM.doNavigate('<%= currNavNode2.getName()%>',0,'','null',1,'<%= escTitlePage %>','')" href="#"><%= titlePage %></a>
The last problem I have is with '&'. Whatever escaping I try, I have a truncated string in the page title at position of the '&'...
Any idea ?
Thanks in advance.
Best regards,
Guillaume

Specify Remote Location for PrintWriter (applet question)

Hello,
I am trying to use a Java applet to access a URL, read in its text content, and save it to a file. The applet is run off an online host (our school server) so I made it a signed JAR file so I could access other hosts. However, here is my problem. The applet itself is in a remote location (our school server, a unix server). I can edit the directory via SSH to add files, and these files become accessible via my homepage (where I'm running the applet from in my browser). But what I need to do is write a file IN THE SAME DIRECTORY as the applet is being run from (ie, the remote directory). But I find that when I run the applet from my browser, it instead by default saves the file I've written to in the local machine's home directory (the desktop). How can I force the applet to save/write to a file in that remote directory (I have the permissions set up on it so that non-owner can write to the directory).
Maybe this isn't possible. I wasn't sure. Here is my code:
      //get URL containing the escape table
      URL inputURL = new URL(inputLocation);
      //make connection to the URL
      URLConnection inputCon = inputURL.openConnection();
      //save URL's contents as text file in same directory
      BufferedReader inputStream = new BufferedReader(new InputStreamReader(inputCon.getInputStream(), "UTF-8"));
      //save with same name as URL file
      File file = new File(inputURL.getFile());
      String filename = file.getName();
      PrintWriter outputStream = new PrintWriter(new File(filename), "UTF-8"); //this didn't work either: outputStream = new PrintWriter(filename, "UTF-8");
      //line of current input
      String line = null;
      //output text file to local text file line-by-line
      while((line = inputStream.readLine()) != null)
        System.out.println("line=" + line); //TEST TO MAKE SURE ACTUALLY READING FILE
        outputStream.println(line);
      }According to my System.out.println, it IS actually accessing the URL and reading each line from the URL's text file correctly, and outputStream.println(line) is correctly printing to the file; it's just doing it in the wrong place!
Also, I should specify: I can't hard encode the file location. It could be anywhere in my html directory. Rather, I want a way to save it in the same directory as the applet was deployed from.

It's for an assignment. All our assignments have to be applets and run from our unix server. I have to access a URL and get data from it, then create that file, then use that file as a reference table for something else.
The tragic part is I think I have everything else working, but I've no way to test it, as I cannot figure out how to access URLs in jgrasp (my IDE - just running the java file itself as an applet within the IDE has the error message about being unable to connect to the URL, since the applet is not signed, but I've no way how to get around that within the IDE itself) so I am testing it directly on the server as a signed jar file so I can at least access the urls.
The requirements stated:
"make a text file (UTF-8 encoding) of the file name t in the same directory where an applet is deployed; "
# A program must be written as an applet in Java. Other programming languages such as JavaScript cannot be used.
# The applet must be deployed on the ITS Web server
I could be missing something, honestly. >_< I might have a word with the TA. I'm just really frustrated since I have everything else working.

Umlaut in request-parameter gets garbled

hi,
when i call a bsp-page on a webas 6.40 and add a request-parameter to the url with a german umlaut in it (like ?name=kölbl), i get a box (�) displayed instead of the correct umlaut when i print it's value to the html-output of that page. it doesn't matter wether the value is read via request->get_form_field or as an auto-attribute.
did anyone face similar problems and solved it?
thanks a lot,
norbert

hi dany,
actually i escaped the url-string already, not by abap but by the javascript function escape(). but this seems not to work correctly (on ie6), so i changed it to a call of encodeURIComponent(), now it works.
thanks,

Problem with openURL when sending Mail

Hi All
I am trying to send mail from my app using
[[UIApplication sharedApplication] openURL: [NSURL URLWithString:emailData]];
emailData contains a google URL that i want to send via email:
http://maps.google.com/maps?f=d&saddr=45.578982,-73.565698&daddr=45.578982,-73.5 65698
my problem is that on Mail app it is showing on the following portion
http://maps.google.com/maps?f=d
i did a couple of tests and find out that the problem is with the "&" i tried & or & did not work cause as soon as it finds teh "&" it drop the whole string that comes after it.
Any help on how I should format this string to appear correctly on my email will be greatly appreciated
thx for your help

You missed the point of my reply. You need to escape anything that you send. When you send 'http://maps.google.com/maps?f=d&saddr=45.578982,-73.565698&daddr=45.578982,-73 .565698' it's just not going to work. As mentioned, you need to Google how to escape variables when sent via GET. Not to mention, your openURL command is wrong as well:
[UIApplication sharedApplication openURL: NSURL URLWithString:emailData];
Where emailData is:
http://maps.google.com/maps?f=d&saddr=45.578982,-73.565698&daddr=45.578982,-73.565698
will absolutely never work. Check the docs for how to use openURL for sending an email using the mailto: protocol. Also, if the emailData that you send using openURL: doesn't look like the escaped string from this tool: http://www.xs4all.nl/~jlpoutre/BoT/Javascript/Utils/endecode.html you aren't properly escaping your URL params.

Filename with Umlaut in cfexecute outputFile attribute

Hi,
I'm running CF10 on SLES11 (Linux) and am experiencing a problem when using Filenames with German umlaut characters (ä,ü,ü etc.) for the outputFile attribute. These filenames are mangled in the Linux filesystem, e.g. "Anästhesie" becomes "An?sthesie".
Same thing happens when umlaut characters are used with "cffile action='write'" in the file attribute, so it is not an option to write the output of cfexecute into a variable and then write the content of that variable to a file using the cffile tag.
I'm pretty sure this is a character set encoding problem, but don't know how to solve it. AFAIK, CF10 uses UTF-8 encoding by default, the filesystem uses ISO-8859-15. How can I make CF store the correct filename in the filesystem?
The filenames are the result of a database query and should remain unchanged so the database reference isn't broken. I'd prefer not having to resort to converting the filenames to pure ASCII (e.g. ä -> ae)
before passing them as outputFile attribute.

Check your MapViewer server log file to see if there is any error messages or exceptions. Set the log level to finest first though, so you can also check the exact XML request string as received by the server. It could be some XML encoding related issue as well (which you can tell by looking at the request as logged at the server side).

LKM - Loading
The LKM - Loading Knowledge Modules - load (or extract data) from one data server to another.
They are named as follows:
LKM <source server technology> to <target server technology> (<module specificity>)
JKM - Journalizing
The JKM - Journalizing Knowledge Modules - setup journalizing on a datastore in a data model.
They are named as follows:
JKM <technology to journalize>
Note: Journalizing uses triggers and views. Therefore technologies that do not support these functions generally do not have an associated JKM.
IKM - Integration
The IKM - Integration Knowledge Modules - integrate data in a target data server from a Staging Area. Frequently, the Staging Area and target space are on the same data server. The IKM can manage options such as data insertion (Append), or update (Incremental Update), etc.
They are named as follows:
IKM <Staging Area data server technology> to <target data server technology> <option managed in the module> (<module specificity>)
IKM <Staging Area and target data server technology> <option managed in the module> (<module specificity>)
Note: The option managed by the module frequently indicate the more complex option supported in this knowledge module. For instance, a module Incremental Update (update) should also be able to manage the option append, which is data insertion, and suppression of data in the target..
CKM - Check
The CKM - Check Knowledge Modules - manage the data quality and cleansing, on static data and on data flows.
They are named as follows:
CKM <Checked Technology> (<module specificity>)
RKM - Reverse-engineering
The RKM - Reverse Knowledge Module - reverse-engineer a data model stored in a given technology. As default, the standard reverse allows to reverse all the information and meta-data in most models. It is required for certain technologies (files for instance) to use a personalized reverse and therefore a RKM. They are named specifically.
SKM - Services
SKM (Service Knowledge Modules) are used to generate the code required for creating data services. This code (typically Java) can be automatically compiled and deployed to a web service container.
