How to get segmentation fault to produce a core file

Hi,
I'm trying to get a program to run on SunOS 5.10, but there's a memory error - Segmentation fault is what the error message says.
By looking around I've found libumem (umem_debug) and I am hoping to use it. Problem is that it wants a core file and the segmentation fault isn't giving me one. I know there's gcore to produce a core dump from a running program, but that's not realisitic here.
1 - the program crashes immediately
2 - i don't know where the error is, so i wouldn't want to force a core dump before the memory has been corrupted.
Anyway, is there some way to explicitly get a segmentation fault to produce a core dump?
Thanks

You may have resource limit disabling generation of core file
Run
#ulimit -c to see your current limit (max. core file size in 512-byte blocks)
Run this command to enable core file generation:
#ulimit -c unlimitedand then try starting your program again - you should get your core.

How to get the attribute value of an XML file??

How to get the attribute value of an XML file??
For example, how to get name and age attributes?
<student name="Joe" age="20" />

What are you using to read the XML file??
On the assumption of JDOM - www.jdom.org. Something along the lines of:SAXBuilder builder = new SAXBuilder(true);
Document doc = builder.build(filename);
Element root = doc.getRootElement();
List children = root.getChildren();
Element thisElement = (Element)children.get(n);
String name = thisElement.getAttributeValue("name")
try
int age = Integer.parseInt(thisElement.getAttributeValue("age"));
catch (Exception ex)
throw new InvalidElementException("Expected an int.....");

Programming help - how to get the read-only state of PDF file is windows explorer preview is ON?

Programming help - how to get the read-only state of PDF file is windows explorer preview is ON?
I'm developing an application where a file is need to be saved as pdf. But, if there is already a pdf file with same name in the specified directory, I wish to overwrite it. And in the overwrite case, read-only files should not be overwritten. If the duplicate(old) file is opened in windows (Win7) explorer preview, it is write protected. So, it should not be overwritten. I tried to get the '
FILE_ATTRIBUTE_READONLY' using MS API 'GetFileAttributes', but it didn't succeed. How Adobe marks the file as read-only for preview? Do I need to check some other attribute of the file?
Thanks!

Divya - I have done it in the past following these documents. Please read it and try it it will work.

How to get ALL validate-errors while insert xml-file into xml_schema_table

How to get all validate-errors while using insert into xml_schema when having a xml-instance with more then one error inside ?
Hi,
I can validate a xml-file by using isSchemaValid() - function to get the validate-status 0 or 1 .
To get a error-output about the reason I do validate
the xml-file against xdb-schema, by insert it into schema_table.
When more than one validate-errors inside the xml-file,
the exception shows me the first error only.
How to get all errors at one time ?
regards
Norbert
... for example like this matter:
declare
     xmldoc CLOB;
     vStatus varchar
begin
-- ... create xmldoc by using DBMS_XMLGEN ...
-- validate by using insert ( I do not need insert ;-) )
     begin
     -- there is the xml_schema in xdb with defaultTable XML_SCHEMA_DEFAULT_TABLE
     insert into XML_SCHEMA_DEFAULT_TABLE values (xmltype(xmldoc) ) ;
     vStatus := 'XML-Instance is valid ' ;
     exception
     when others then
     -- it's only the first error while parsing the xml-file :
          vStatus := 'Instance is NOT valid: '||sqlerrm ;
          dbms_output.put_line( vStatus );
     end ;
end ;

If I am not mistaken, the you probably could google this one while using "Steven Feuerstein Validation" or such. I know I have seen a very decent validation / error handling from Steven about this.

How To Get FileType and MIME Type from a File

Hi,
I am using following ways to get FileType and MIME Type.
I am able to get file type, but I am getting MIME Type as */*
Can any one please let me know how to get MIME Type, but it should not be time consuming process.
For File Type I am using following Code:
private String getFileData(InputStream inStream) {
fileName = C:\temp\temp.tiff
String filePath = Util.createTempFile(fileName);
RandomAccessFile raf = new RandomAccessFile(filePath, "rw");
while (inStream.available() > 0) {
     byte[] buf = new byte[inStream.available()];
     inStream.read(buf);
     raf.write(buf);
inStream.close();
raf.close();
File file = new File(filePath);
JFileChooser chooser = new JFileChooser();
String fileType = chooser.getTypeDescription(file);
file.delete();
//MIME Type I am getting from
DataHandler data = new DataHandler(new DocumentSource(inStream));
data.getContentType();
data.getContentType() is not working well in all cases.
Can any one help me on this.
Thanks in advance,
Ram.

DATA TRANSFER - How to get a SINGLE SPACE in downloaded txt file from UNIX?

Hi Experts,
Am sending data from SAP to UNIX/ Application server and text file on desk top as well.
So, I am keeping a single character just SPACE at the END of each record.
Then, When I see the downloaded text file, I found a SINGLE SPACE at the end of each record, fine.
Then, by using CG3Y t code, I downloaded the UNIX file to my desk top.
But, When I see this UNIX downloaded file from UNIX, I did NOT find any SPACE at the end of each record!!!
Am doing every thing same in both cases.
So,
1 - Why its happening in case of UNIX file?
2 - How to get a SINGLE SPACE at the END in the downloaded file from UNIX?
thanq

Its there, I am talking abut this -
OPEN DATASET - linefeed
Syntax
... WITH { NATIVE
         | SMART
         | UNIX
         | WINDOWS } LINEFEED ... .
Alternatives:
1. ... WITH NATIVE LINEFEED
2. ... WITH SMART LINEFEED
3. ... WITH UNIX LINEFEED
4. ... WITH WINDOWS LINEFEED
Effect
: These additions determine which line end marker is used for text files or legacy text files. If these additions are used, the profile parameter abap/NTfmode is ignored. Simultaneous specification of the values "UNIX" or "NT" in the addition TYPE is not permitted.
If these additions are not used, the line end marker is determined as follows, depending on the operating system of the current application server:
The line end marker for Unix is "LF". Under Unix, OS390 and OS400, only "LF" is used for reading and writing.
The line end marker for MS Windows is "CRLF". Under MS Windows, however, the values of the profile parameter abap/NTfmode can also be used to set whether new files are handled according to Unix conventions or Windows conventions. If the profile parameter has the value "b", the Unix line end marker "LF" is used. If the profile parameter has the value "t" or is initial, the Windows line end marker "CRLF" is used. The setting using the profile parameter can be overridden with the addition TYPE and the value "UNIX" or "NT". If an existing file is opened without the addition TYPE, this is searched for the first line end marker ("LF" or "CRLF"), and this is used for the whole file. If no line end marker is found, the profile parameter is used. This applies particularly if an existing file is completely overwritten with FOR OUTPUT.
If an addition WITH NATIVE|SMART|UNIX|WINDOWS LINEFEED is used, this setting can be changed for the open file using the statement SET DATASET. If neither of the additions is used, the line end marker also cannot be changed using SET DATASET.
Notes
: Without the use of an addition WITH LINEFEED, the line end marker is dependent on diverse implicit factors such as the operating system of the application server, a profile parameter, and line end markings that are already used. For this reason, the explicit use of WITH LINEFEED is recommended, which renders the use of the addition TYPE for setting the line end marker obsolete.
The line end marker that is currently used can be determined for every open file using GET DATASET.
Alternative 1
... WITH NATIVE LINEFEED
Effect
: This addition defines the line end marker independently of the access type according to the operating system of the application server, i.e. "LF" for Unix OS390 or OS400, and "CRLF" for MS Windows.
The line end marker is interpreted according to the current codepage. If a code page is explicitly specified using the addition CODE PAGE, the characters of the line end marker must exist be available or be written in accordance with this code page.
Note
: The addition WITH NATIVE LINEFEED is intended for editing files on an application server that can also be accessed by other means. The addition receives the appropriate line end marker without the program needing to know the operating system.
Alternative 2
... WITH SMART LINEFEED
Effect
: This addition depends on the access type:
In files that are opened for reading using FOR INPUT, both "LF" and "CRLF are interpreted as a line end marker. When opening an EBCDIC file with the addition CODEPAGE, in addition to "LF", "CRLF", and the EBCDIC character strings, the corresponding ASCII character strings are also recognized. In addition, the EBCDIC character "NL" (line separator) is also interpreted as a line end marker.
In files opened for appending or changing with FOR APPENDING or FOR UPDATE, the program searches for a line end marker that is already used in the file. In this process, first the end of the file is identified. If no line end marker is found there, a certain number of characters at the beginning is analyzed. If a line end marker is found, this is used when writing to the file. This is also affected by the addition CODE PAGE. For example, ASCII line end markers are recognized and used in a file opened with EBCDIC, but not the other way round. If no line end marker is found or no search is possible (for example, if the file is opened with the addition FILTER), the line end marker is determined according to the operating system of the application server, as with the addition WITH NATIVE LINEFEED.
In files opened for writing using FOR OUTPUT, the line end marker is determined according the operating system of the application server, as with the addition WITH NATIVE LINEFEED.
Note
: The addition WITH SMART LINEFEED is intended for the generic editing of files in heterogeneous environments. The line end marker is recognized and set for different formats. The use of this addition is the best solution for most application cases.
Alternative 3
... WITH UNIX LINEFEED
Effect
: The line end marker is set to "LF" regardless of the access type and operating system of the application server.
The line end marker is interpreted according to the current code page. If a code page is specified explicitly using the addition CODE PAGE, the characters of the line end marker must be available or be written according to this code page.
Note
: The addition WITH UNIX LINEFEED is intended for editing Unix files in which the specific line end markers are to be retained, even if the operating system of the current application server is MS Windows.
Alternative 4
... WITH WINDOWS LINEFEED
Effect
: The line end marker is set to "CRLF" regardless of the access type and operating system of the application server.
The line end marker is interpreted according to the current code page. If a code page is specified explicitly using the addition CODE PAGE, the characters of the line end marker must be available and be written according to this code page.
Note
: The addition WITH WINDOWS LINEFEED is intended for use with MS Windows files in which the specific line end marker is to be retained, even if the operating system of the current application server is Unix, OS390 or OS400.

Hi,
I don't know if this works:
perform SET_TRAIL_BLANKS(saplgrap) using 'X'.
perform SET_FIXLEN(saplgrap) using '0' '060'. "put length of your line from-to
... download ...
It will put space at the end of your line, according to the length.
Hope it works,

How To Get The CLOSE Event In a JSP File?

Hello everybody,
Right now I am working in a JSP project which is about access log, when the users start , oprate, or close the system, the access log system works. I am in trouble in that when the users close the system, how can I get the close event?
The JSP file contains the following fields :
Close Window
How to add code to get the CLOSE Event and submit to the service?
And If I hit the "Close Button"(on the right-top of the window), how can I get the CLOSE event, too?
Can anyone tell me?

1. Add a hidden field:
<input type="hidden" id="status" value="">2. modify <a href="index.jsp" onclick ="parent.window.close( );">Close Window</a> with <a href="index.jsp" onclick ="closefn();">Close Window</a>3. Add a javascript
<script language="javascript">function closefn(){
document.getElementById('status').value="close";
document.form.action="";
document.form.method="post";
document.form.submit();
parent.window.close( );
}4. Now on the action page get the value of status by request.getParameter("status"); and log it.

How to get the pull path name from a file upload window

Hello everyone!
I have encountered the following problem with the following JSP code:
<form method="post" action="filename.jsp">
Upload JAVA program:
<input type=file size=20 name="fname" accept="java">
<input type=submit value="go">
</form>
<%
String s = "";
if (request.getParameter("fname") != null)
s = request.getParameter("fname")
%>
The value of s is alway the filename. However I want to get the full path in addition to the filename, so that I can read the file. Does anyone know how to get the pull name of the file?
thanks a lot in advance,

Dear Sir,
thanks a lot for your reply. Please let me explain what I intended to do: I want to upload a file from the local machine and then read the content of the file. Therefore I need to the fullpath of the filename like /var/local/file.java instead of file.java. The latter is what I got.
The problem I have with your code is that the function like "request.getServerScheme()" is not recognized. Maybe is it because I didn't install servelet package? I only installed javax package btw. Also my application runns on Tomcat server if this could give you some information. The error message I had is as follows:

Hi,
when you are transfering the data to file
loop at itab in wa_itab.
counter = count + 1.
transfer wa_itab to fiel.
if counter = 100
    clear wa_itab.
    transfer wa_itab to fiel.
    transfer wa_itab to fiel.
    transfer wa_itab to fiel.
   clear counter.
endif.
endloop.

How do I get the real path of the xml file.
Edited by: shashiwagh on Jan 29, 2010 11:46 AM

Hi,
if your XML file is inside a package you can easily get it from the classloader.
Note that your application maybe packaged inside a jar so it is not safe to use java.io.File for this purpose.
You have an xml file in :
com/gts/xml/MyXML.xml
in a class of the same module (that will packaged in the same jar) for example com.gts.java.XmlLoader :
// To get the stream :
InputStream is = this.getClass().getResourceAsStream("/com/gts/xml/MyXML.xml");
// Or the URL :
URL xml = this.getClass().getResource("/com/gts/xml/MyXML.xml");Hope it helps.
