please help me out.

You have to generate a replacement for the default ServletOuputStream so that every time the data is sent to the browser (via the output stream) it is also sent to a tool that can generate a String or StringBuffer (a StringWriter does this nicely). One way to do this is to generate a ServletOutputStream implementation that wraps a ServletOutputStream and StringWriter. You would implement each method in ServletOutputStream and pass the parameters to both wrapped streams, i.e.:
public class ServletOutputStreamAndStringWriter extends ServletOutputStream {
private ServletOutputStream sos;
private StringWriter sw;
pubic ServletOutputStreamAndStringWriter (ServletOutputStream sos, StringWriter sw) {
    this.sos = sos;
    this.sw = sw;
public void print(String s) {
    sos.print(s);
    sw.write(s);
public void println(String s) {
    sos.println(s);
    sw.swrite(s+System.getProperty("line.separator"));
//etc... for all methods including flushes and closes...
}Next you have to insert the ServletOutputStream implementation above into the application in a manner that doesn't require a re-write of the rest of your code. The best way to do this is to generate a ServletResponseWrapper implementation that returns your new implementation of the ServletOutputStream in the getOutputStream() method:
public class SplitOutputServletResponse extends ServletResponseWrapper {
private ServletOutputStreamAndStringWriter sosasw;
public SplitOutputServletResponse(ServletResponse sr, ServletOutputStreamAndStringWriter sosasw) {
    super(sr);
    this.sosasw = sosasw;
public ServletOutputStream getOutputStream() { return sosasw; }
}Now all you have to do is replace the response you use in your application with this wrapper. The best way to do it is through a Filter:
public class SplitOutputFilter implements javax.servlet.Filter {
private FilterConfig fc;
public void init(FilterConfig fc) { this.fc = fc; }
public void destroy() { }
/* This is where the filtering work gets done. You get a request and a response, you pass the request,
      replace the response, and let the rest of the filter chain do its work (the JSP page gets generated and the
      response to the client is generated). Then after the rest of the filter chain you get the text out of the
      StringWriter you generated for the ServletOutputStream
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) {
    // After the JSP does its work, the StringBuffer will be generated from this StringWriter
    StringWriter stringBufferFromHere = new StringWriter();
    // This is the tool used to deliver the JSP output to the above StringWriter
    ServletOutputStreamAndStringWriter output = new ServletOutputStreamAndStringWriter (response.getOutputStream(), stringBufferFromHere);
    // And this is the tool used to deliver the above output stream to the JSP pages
    SplitOutputServletResponse sosr = new SplitOutputServletResponse(response, output);
    // Now we replace the incoming ServletResponse with the wrapper generate above for the rest of the FilterChain
    // which includes the actual execution of the JSP
    chain.doFilter(request, sosr);
    // By the time we get to this point, the JSP has already generated the page. We need to extract the text as
    // a StringBuffer, which we should have access to via the StringWriter
    StringBuffer jspOutput = stringBufferFromHere.getBuffer();
    // Then do whatever you need to do with the buffer... Note that the FilterContext provides a reference to the
    // ServletContext which could help you store the buffer, put it in DB, or whatever you wanted to do with it...
}Filters start at the beginning of a request cycle, can be mapped to particular URLs or groups of URLs. To see how to use them see: http://java.sun.com/products/servlet/Filters.html which also has some similar examples.

Need help for how to putting arabic content in java properties file

Hi all,
we have to support arabic in Java application.
For that we are using java propeties file where key and value pair is used.
In the Microsoft excel sheet arabic content is coming properly from right to left direction.
When same thing is copied and paste in java properties file contents direction is reversed that is it is coming from left to right as in english.
Please help how to put the arabic contents in propeties file
Regards
Vidya

So in terms discussion.
First I would suggest that you get a hex editor and validate exactly what is in the properties file. It appears to me that you are using one or more editors that are adjusting the display for you and thus that makes it hard to determine where the problem is. A hex editor should not adjust the display. Although even then you might want to right a simple java app and have it read bytes and print them just to validate that the hex editor isn't doing something.
Only after you are exactly sure how the bytes appear in the file then proceed with other steps.
For the java GUI only test the following.
1. Properties file has it left to right then the java GUI displays it correctly right to left or not?
2. Properties file has it right to left then the java GUI displays it correctly right to left or not?
Myself I would expect that 2 should be the correct way to implement this. However that is dependent upon you correctly invoking the api as well. So if 2 is not working then you might want to look at the api. It might also have something to do with GUI display properties (of which I know even less.)

Pls help! How to put JSP import statement...

Hi, I just created a simple iView JSP that imports htmlb classes and now I'd like to import my own java classes onto it. For example, in my other projects, my JSP's have <%@ page import="project28.practice.contextClass" %> on top of the page. I currently have a file called practice.jar
If I want to put this import statement into my simple iView JSP and use it, what would I have to do/configure?, do I have to transform it into a .par file? Or can I transport the jar file to the portal? Any changes on NetWeaver?
I am new to this so any detailed help or suggestions are greatly appreciated!
Thanks again,
Baggett

Hi Detlev, thank you for your response! I'd like to include more details of my situation right now: I have 2 projects on NetWeaver:
Project#1: Java Web application Project. (jar files, WEB-INF, WEB-INF/web.xml, JSP's...)
Project#2: Portal Application Project. (JSPDynPage, sap plugins, PORTAL-INF/portalapp.xml, JSP)
I'd want my JSP file in Project#2 to call some classes from the jar files of Project#1.
From my understanding, to do this I need to make a .par file out of Project #1 and then upload the par file to my SAP EP6.0 so that my future JSP's can import classes from it. Am I correct?
I am confused right now as to how to really do this. On Netweaver, I am getting a Error when I try to do: File --> New --> Project --> Portal Application --> Create a Portal Application Project > I then enterProject Name: TestProject28, Project root folder: c:\TestProject\webapps\project1
--> "ERROR: Invalid project description, Reason:An error has occured while trying to create the project structure"
If possible can you please provide detailed instructions on how to configure or build a par file out of my java web application stated above?
Thank you so much for your time and help!

How to flush JSP content from a portal class for initial content display?

Hello,
I have a JSP that is loaded from the JSR-168 portlet class. The JSP is used for doing a database search. As results come back, I want to flush the JspWriter ("out" variable) buffer so that partial results are displayed to the user as they come back.
The flushing of the content does not occur in this JSP. If, however, I launch a JSP page directly (not through the portlet class)in its own browser window, and the same code is run, the flushing occurs and I can get results displayed as they are returned.
There is something different in the JSP version that is loaded from the portlet class that is preventing the flushing from occurring.
This just may be an issue where the portal engine waits to display all content (to include my portlet) all at once.
Any thoughts? Is there another way to do this?
Thanks - Peter

From http://www.htmlhelp.com/reference/html40/forms/input.html:
A form that includes a file INPUT must specify METHOD=post and ENCTYPE="multipart/form-data" in the <FORM> tag. CGI libraries such as CGI.pm allow simple handling of such forms.
Form-based file upload is unsupported by many currently deployed browsers. Authors should provide alternative methods of input where possible.
The following example allows the user to upload an HTML document for validation:
<FORM METHOD=post ACTION="/cgi-bin/validate.cgi" ENCTYPE="multipart/form-data">
<P>Select an HTML document to upload and validate. If your browser does not support form-based file upload, use one of our alternate methods of validation.</P>
<P><INPUT TYPE=file NAME="html_file" ACCEPT="text/html"></P>
<P><INPUT TYPE=submit VALUE="Validate it!"></P>
</FORM>
Your servlet would then have to process whatever data is put into that parameter. You can look at O'Reilly's servlet utilities, or one of the other other links here:

How to put iTunes content on one drive, everything else on another

I have had an original Pro since '06. It doesn't run Mav, so I popped for the new one. Oddly enough, the price was exactly the same once inflation was considered. Thank you Canadian Petrodollars!
Anyway... on my old machine I had an SSD called Fast with the OS and apps on it. I had moved my user folder to Big, a 1 TB spinny. The VAST majority of the space on Big was in my Movies, Pictures and Music folders.
On the new machine, Big is a USB portable drive. Theoretically, it might be nice to be able to plug it into another machine and work on those files. But I think that means my new MP is dead at that point because there's no User directory for my login.... is that actually correct?
If it is, is there a better way to do this?
- Should I move my Movies, Pictures and Music folders to the new drive and put everything else on the SSD?
- Or is it cool to put my User folder on the USB and work like I used to?
What are other MP users doing?

This user tip is actually about moving your Home Folder:

How to put Avantgo content into SD card of Palm T3

I have a Palm T3. I have been using Mark/Space v4 to regularly sync my T3 with Avantgo. I have an 8MB Avantgo account. I am running out of internal memory.
I tried to use Internet Sharing feature of Mark/Space to sync directly from Avantgo while my TT3 sits in the cradle. It did not work.
My computer is an iMac running 10.4.6 and Internet access is via an Apple AEBS connected to a bridge ADSL modem.
Has anyone succeeded in this: using Internet Sharing feature of mark Space v4 to allow Avantgo on the Palm device to sync content into SD card?
I assume I do not need to set any proxy settings. Could that be a problem given my setup in a home environment using a regular ISP?
Any help would be appreciated!

Internet sharing works just fine for me, as does the Mark/Space Conduit for AvantGo, but there appears to be a small catch.
The AvantGo-provided Palm .prc file—currently at version 5.7 build 46—apparently will not operate properly if moved to an SD card. It, and the AG Connect file, apparently must reside in main memory to operate. This isn't a Missing Sync issue, it's a shortcoming of the AvantGo application on your Palm.
Even using an almost universally accepted method of moving these files to an SD card, using PowerRUN, didn't work. Here are the results of an AvantGo-only synchronization attempt: first with the applications on the SC card, then with them back in main memory where they have always resided on my hanheld…
Sync starting at 04/30/06 14:38 (14:38:58) on USB (5.1.0)

Note the Please upgrade your AvantGo software… log entry when the applications reside on the expansion card. Simply using PowerRUN to return them to main memory resulted in a successful synchronization and allowed me to browse AvantGo content using internet sharing.

How to keep the JSP content constant when page refresh?

Hi All,
When I click page tabs in WLP, it will trigger a refresh event.
The portlet has a webflow with a refresh event whose destination is
lastContentUrl(referent-namespace is portal, cloned from portlet2.wf).
The question is when the page changed, the jsp files which use
request.getParameter() to get parameters will fail to fulfill what they
need because the event provide none parameter.
So that everytime page changed, these portlets will have quite strange
contents.
How to keep these content constant when page changed?
Sincerely,
Alan.

The problem is still there if the jsp file is about inserting a new record
into the database.
If these parameters are gotten from the session, mutliple insertings will be
attempted when the portlet is refresh.
Maybe we can put some control flags in the session to judge the correct
behavior, but the method results the session full of parameters(control
flags).
Or is there any better design?
Alan.

Alan,
You could use the session to put your parameters in instead of letting itride completely
on the request object. Although, your question is more than just makingthe content
reappear, it’s about holding state. The project that I am working on, theusers
decided that they want the page portlets to go back to the "normal" state,not the
"Maximized" view. So, I put a processor in between the internal.refreshwildcard
and the Preprocessor input processor so that all the portlets would beseen in their
"normal" state.
Good Luck

How do you transfer the content from an iPhone to a PC? I have to use a PC for a while and don't know how to put my stuff on to there from my phone

How do you transfer the content from an iPhone to a PC? I have to use a PC for a while and don't know how to put my stuff on to there from my phone

If you're talking about music and movies an i-device was not designed for unique storage of media. It is not a backup device and media transfer was planned with you maintaining a master copy of your media on a computer which is itself properly backed up against loss. Syncing music and movies is one way, computer to device, updating the device content to the content on the computer, not updating or restoring content on a computer. The exception is iTunes Store purchases which can be transferred from a device to a computer.
iTunes Store: Transferring purchases from your iOS device or iPod to a computer - http://support.apple.com/kb/HT1848 - only purchases from iTunes Store
For transferring other items from an i-device to a computer you will have to use third party commercial software. See this document by turingtest2: Recovering your iTunes library from your iPod or iOS device - https://discussions.apple.com/docs/DOC-3991

How to use ora:parseEscapedXML() Function with String Content

Hello,
I am receiving a ResponseMessage that returns a string, but the content of the string is actually XML.

Hello,
I am attempting to provide more information in order to hopefully get some better guidance here.
1) The BPEL process I built receives input from a client that is one of city name or region name or postal code or country name and returns a list of customer records with their AccountNumber, LastName, FirstName, Email, Address, City, Region, PostalCode and Country. The BPEL flow invokes a packaged integration Web Service that retuns the records in a string whose content is XML (see XML fragment below).
2) The string content returned is vaiable based on the input (i.e. city name="London")
Two customer records from XML literal fragment copied from string result:
<?xml version="1.0" encoding="ISO-8859-1"?>
<recordset>
<customer>

<CustFname>Thomas</CustFname>
<CustEmail>[email protected]</CustEmail>
<CustAddress>120 Hanover Sq.</CustAddress>
<CustCity>London</CustCity>
<CustRegion></CustRegion>
<CustPostalCode>WA1 1DP</CustPostalCode>
<CustCountry>UK</CustCountry>
</customer>
<customer>

<CustCity>London</CustCity>
<CustRegion></CustRegion>

<CustCountry>UK</CustCountry>
</customer>
I want to <assign> each record from the packaged integration service result (the string whose content is XML) to a complexType variable defined within the BPEL Process WSDL (see example below).
XML fragment from BPEL WSDL:
<element name="QueryResult" type="client:recordType"/>>

<sequence>
<element name="customer" type="client:customerType" maxOccurs="unbounded"/>
</sequence>
</complexType>

How to write the contents of string buffer to a file

hi all
how is it possible to write the contents of a string buffer to a new file (ie i have to create a file and write in it )
this my string buffer

s.append(output);
s.append(" You have been Sucessfully authenticated</b>");
s.append("</body></html>");
so please can anyone help me

for nice examples of how to do things you may look int [url http://javaalmanac.com]Java Almanac
or more specifficly: [url http://javaalmanac.com/egs/java.io/WriteToFile.html?l=find]Writin to a File
in case you don't know how to apply that example on your code, since you have StringBuffer instead of String, then look at [url http://java.sun.com/j2se/1.4.2/docs/api/]API Specification of [url http://java.sun.com/j2se/1.4.2/docs/api/java/lang/StringBuffer.html]StringBuffer, and see if there is some method like toString() or similar, that would help you convert your StringBuffer to a String.
