How to use XMLEncoder to save Complicated XML??

How to use XmlModify to sort the XML Data?

Hello,
I saw some examples explain how to use XmlModify in BDB XML package. I want to sort the XML data by several elements but my Java program could not work correctly.
<CustomerData>
<Transaction>
<DLSFIELDS>
<ADR_PST_CD>12345</ADR_PST_CD>
<CLT_IRD_NBR>002</CLT_IRD_NBR>
</DLSFIELDS>
</Transaction>
<Transaction>
<DLSFIELDS>
<ADR_PST_CD>12345</ADR_PST_CD>
<CLT_IRD_NBR>102</CLT_IRD_NBR>
</DLSFIELDS>
</Transaction>
// many nodes like transaction ...
</CustomerData>
My XQuery script was executed successfully in the shell. The script looks as follows:
"for $i in collection('sample.dbxml')/CustomerData/Transaction order by xs:decimal($i//ADR_PST_CD), xs:decimal($i//CLT_IRD_NBR) return $i".
The Java code :
// create XmlManager
XmlManager manager = // ...;
// open XmlContainer
XmlContainer container = // ...;
XmlQueryContext context = manager.createQueryContext(XmlQueryContext.LiveValues, XmlQueryContext.Eager);
XmlQueryExpression expression = manager.prepare("for $i in collection('sample.dbxml')/CustomerData/Transaction order by xs:decimal($i//ADR_PST_CD),xs:decimal($i//CLT_IRD_NBR) return $i", context);
XmlModify modify = manager.createModify();
XmlUpdateContext uc = manager.createUpdateContext();
XmlDocument xmldoc = container.getDocument("sample.xml");
XmlValue value = new XmlValue(xmldoc);
long numMod = modify.execute(value, context, uc);
System.out.println("Peformed " + numMod     + " modification operations");
Could you point out the errors above or offer some suggestion?
Thanks.

I have other question of the sorting issue. Here are a large XML need to sort so I have to split it to multiple small XML files. After importing these files, I will use the XmlModify and XQuery to sort them. I'm not clear on the multiple XML files processing.
1. Can the BDB XML ensure that all these XML files were sorted or how to update all documents with same logic.
2. If I want export all these sorted documents, how can I ensure these files processed in sequence? Which document needs process first?
The export method:
public void export(String outputfile)throws Exception{
final int BLOCK_SIZE = 5 * 1024 * 1024; // 5Mb
try{
File theFile = new File(outputfile);
FileOutputStream fos = new FileOutputStream(theFile);
byte[] buff= new byte[BLOCK_SIZE];
XmlResults rs = container.getAllDocuments(new XmlDocumentConfig());
while(rs.hasNext()){
     XmlDocument xmlDoc = rs.next().asDocument();
     XmlInputStream inputStream = xmlDoc.getContentAsXmlInputStream();
     long read=0;
     while(true){
     read = inputStream.readBytes(buff, BLOCK_SIZE);
fos.write(buff,0,(int)read);
     if(read < BLOCK_SIZE) break;
inputStream.delete();
xmlDoc.delete();
rs.delete();
//MUST CLOSE!
fos.close();
catch(Exception e){
System.err.println("Error exporting file from container " + container);
System.err.println(" Message: " + e.getMessage());
Thanks.

How to use method POST to send XML using utl_http?

Hi,
I am trying to work out how to use the POST method to mimic submitting data from a HTML form, using utl_http.
I cannot use SOAP for this as the people I am sending the data to are just expecting an XML document to be sent to a standard CGI script running on their web server.
There is a lot of documentation on how to submit data using the POST method (using Utl_Http.Write_Text etc), but I cannot find anything that tells me how to submit form variables.
The examples on OTN say this:
"Alternatively use method => 'POST' and Utl_Http.Write_Text to
build an arbitrarily long message"
but don't tell me how to actually place the data into the required input parameters of the CGI program I am hitting.
I need to hit a URL such as
www.asite.com/cgiprogram
and pass in a parameter, eg
in_param="test+data"
I am currently doing this as a GET, which works, but the XML document I am passing in could potentially be bigger than the GET method will allow.
Any help would be greatly appreciated.
Thanks,
Leon.

How to use jstl in weblogic 8.1

I tried to use JSTL in my jsp file and I add
          <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %> at the top line. But the server reported
          java.lang.NoClassDefFoundError: javax/servlet/jsp/el/VariableResolver
          how to solve this problem?

WebLogic 8.1 supports JSP 1.2, which doesn't natively implement the JSTL or the expression language. If you download the Jakarta Taglibs implementation of the JSTL (for JSP 1.2, not JSP 2.0), then you can use the JSTL taglib as a normal taglib. Note that this doesn't give you the ability to use the other JSP 2.0 tag features, like using the expression language in body content.
          Make sure that you use the uri value specified in the tld that you're using. I believe the values are different between the JSP 1.2 and JSP 2.0 versions.

Hi,
When we develop simple XML report also we used to get single data source either generated either from RDF or PL/SQL, in OAF XML data is coming from VO and XML Publisher API’s will process that data.
This approach works fine if you are having one VO, but if you are having two VOs then it is not possible (As per my understanding and comparing this scenario with simple XML publisher report).
I also faced same problem few months back, on my form I was having two VOs one for header and other for Lines and I have generate Report to show the data for both Headers and Lines. In my case I created a separate VO that was containing both Header and Line details and I was passing header Id to query that. I used query this VO only when someone clicks on “Print” button and it worked fine for me.

How to use java to create an XML document from an SQL database?

Hi,
I'm a complete novice at XML and have only recently started programming in Java.
I'm currently trying to develop a package in Java 1.1.8 which requires a set of very specifically formatted XML documents. These documents would need to be updated regularly by people with no knowledge of Java and I would like to make it as simple as possible.
Since the data will already be in an SQL database, I thought it might be possible to generate the XML documents from the data using a small Java application, but I'm not too sure how to go about this or if this is even possible! Any help or pointers in the right direction would be very much appreciated.

Do you have the option of upgrading to a newer version of the JDK?
JAXB does what you are wanting very easily. Also there are tools if you don't want to write your own. JAXB is available as early release on Sun's site as is the newest JDK. Otherwise, you have to design a factory and interface that will do this for you (which is what JAXB basically is in a very simplified view).

How to use the 'next' softkey in XML Directory - SPA504G

I have the basic XML Directory stuff working (CiscoIPPhoneDirectory) on the SPA504G. However I realise I can only display 32 entries and I note that there is a "next" softkey enabled, however it seems to not do anything. How can I link this button press to fetching a new url with the next page of 32 results - I am ok dealing with the server side of this.
Looking at the xsi_dev_guide (which I am not sure is applicable to the SPA504G), talks about adding a Refresh HTTP Header, however it is a bit vague and whenever I add it to the HTTP response, the spa504 barfs (invalid response).
Do I need to program the next softkey to send a URL or something?

Do I need to program the next softkey to send a URL or something?
Yes, definitely. The "Next" soft key is not magic key of any kind. It just standard "request a page from HTTP server" key. It should issue a HTTP request for next page. Like "Prev" key is asking for previous page content.
So you need something like:
<SoftKeyItem>
<Name>Next</Name>
<URL>https://.../Cisco/Directory.php?page=2</URL>
<Position>3</Position>
</SoftKeyItem>
Note that you should NOT claim Next key on last page. Phone will choke on empty CiscoIPPhoneDirectory (e.g. no entry). For same reason you should not declare Prev key on first page.
Looking at the xsi_dev_guide (which I am not sure is applicable to the SPA504G), talks about adding a Refresh HTTP Header, however it is a bit vague and whenever I add it to the HTTP response, the spa504 barfs (invalid response).
Yes, xsi_dev_guide apply to SPA504G as well. Although Refresh is not claimed by a formal standard, it's de-facto standard recognized by many browsers already. Thus it's not documented in detail heres. In the context of example above you should emit ...
Refresh: 0; url=https://.../Cisco/Directory.php?page=2
... header here.
Rate useful advices. It will help others to found solutions.

How to use cursor function for nested xml

Hi,
i have a query for XMLQuery like
select * from bills where bill_id=????
it results in something like
<bills>
<bill>
<city>london</city>
<amount>44</amount>
</bill>
<bill>
<city>london</city>
<amount>988</amount>
</bill>
<bill>
<city>new york</city> <amount>59</amount> </bill>
</bills>
but i want xml output to be sorted for city names adding one more level location like
<bills>
<location city="london">
<bill>
<amount>44</amount>
</bill>
<bill>
<amount>988</amount> </bill>
</location>
<location city="new york">
<bill>
<amount>59</amount> </bill>
</location>
</bills>
it should be possible to iterate through the same table to gather informaton with the help of cursor function, but never used CURSOR before.
any idea?

It IS the issue .. you need to provide a SAMPLE so we can see what you're doing ..
How are you "passing it in" ?
option A:

and nvl(sn.c_attribute1,'x@#$%') in nvl(in_var,'x@#$%')

How to use jstl variable in a jsp page

Hi all,
I am new to JSTL and i want to access the value of jstl in jsp.
when i use the tag like below it is displaying the value ""

But it is showing error like varialbe can not be resolved: ackvalue
can anybody please help me regarding this?
Waiting for your warm response.
Thanks in advance

Hi,
Thanks for your immediate reply.
I am able to display the ackvalue when i am using
<c:set var="ackvalue" value="${ack}"/>

But my actual requirement is to use the ack value in
switch statement. if i can assign the value to a
String variable, then it si easy for me to proceed.
Please help me in this regard.
Thanks,You can use the c:choose, c:when and c:otherwise tags
<c:choose>
    <c:when test = "${ackvalue == 1}">
           //do stuff
    </c:when>
    <c:when test = "${ackvalue == 2}">
