Using UTL_TCP to post xml

All,
we were using UTL_HTTP for XML post and retrieve result. It kept running into transfer_timeout trouble (oracle 9.2.*)
So now we are trying to use UTL_TCP to post xml.
But I am not sure how the sequence will be.
I woulc apppreciate if you guys could point me to the right place. All the samples I saw so far are for email or ftp.
Thanks.
Steve

UTL_HTTP uses UTL_TCP underneath so using UTL_TCP yourself possibly won't solve the problem. One common reason of transfer-timeout exception is that the length of the POST data is not specified or is incorrect in the content-length header, causing the HTTP server to keep waiting to read more from your side but you have posted the whole data.
Can you post your codes that use UTL_HTTP here (if possible) and let us take a look?

Error while posting xml file to URL using URLConnection

Hello everyone,
I am facing an issue from long time related to URLConnection. If this would be resolved by your help then I would be very grateful to you.
One application which posts xml file to URL hangs and after waiting for 5 mins it throws 504 error:
java.io.IOException: Server returned HTTP response code: 504 for URL: http:hostname.
at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:715)
Same application is running fine without error on another environment from last 5 years. But on another env it is erroring out from the day 1.
We have many workarounds in place none worked.
I tried to use HttpClient from apache but that too hanged at URLConnection.getInputStream() method call.
App is running on iPlanet web server 6.1 using JDK 1.4.0_03
We still dont know why this program hangs at that particular line in only one env but many times it runs fine. That means 30% of the times it posts xml file without error but 70% times it errors out. So our program logic is to retry until post is successful.
Once this issue is resolved we will remove the logic of trying again and agian.
Please provide inputs.
Thanks,
Nitin

The HTTP response 504 means that the server, acting as a gateway, has not received a response from an upstream server in the time it expected.
I think this is problem is due to the remote server that receives the XML and takes too long to return a response to the local application that posted the XML.
Try HttpClient and set the timeout variable of the HttpClient instance used.
Here http://svn.apache.org/viewvc/jakarta/commons/proper/httpclient/trunk/src/examples/PostXML.java?revision=480424&view=markup
a Post XML sample.
NB: HttpClient > setTimeout method is deprecated. See : http://jakarta.apache.org/commons/httpclient/apidocs/index.html for an alternative
Hope That Helps

How can I use a 3rd party XML parser such as xerces with OC4J ?

Hi all tech experts,
I am using Oracle Application Server 10g Release 2 (10.1.2) and i have
installed Portal and Wireless and OracleAS Infrastructure on the same
computer.
i tried all the solutions on this thread
Use of Xerces Parser in out application with Oracle App Server 9.0.4
but still fighting.
I have also posted this query on OTN on following thread
How can I use a 3rd party XML parser such as xerces with OC4J?
but no reply....
Please help me on this issue.
Since OC4J is preconfigured to use the Oracle XML parser which is xmlparserv2.jar.
i have read the following article which states that
OC4J is preconfigured to use the Oracle XML parser. The Oracle XML parser is fully JAXP 1.1 compatible and will serve the needs of applications which require JAXP functionality. This approach does not require the download, installation, and configuration of additional XML parsers.
The Oracle XML parser (xmlparserv2.jar) is configured to load as a system level library of OC4J through it's inclusion as an entry in the Class-Path entry of the oc4j.jar Manifest.mf file. This results in the Oracle XML parser being used for all common deployment and packaging situations. You are not permitted to modify the Manifest.mf file of oc4j.jar.
It must be noted that configuring OC4J to run with any additional XML parser or JDBC library is not a supported configuration. We do know customers who have managed to successfully replace the system level XML parser and the Oracle JDBC drivers that ship with the product, but we do not support this type of configuration due to the possibility of unexpected system behavior and system errors that might occur from replacing the tested and certified libraries.
If you absolutely must use an additional XML parser such as xerces, then you have to start OC4J such that the xerces.jar file is loaded at a level above the OC4J system classpath. This can be accomplished using the -Xbootclasspath flag of the JRE.
i have also run the following command
java -Xbootclasspath/a:d:\xerces\xerces.jar -jar oc4j.jar
but no success.
How could i utilize my jar's like xerces.jar and xalan.jar for parsing instead of OC4J in-built parser ?
All reply will be highly appreciated.
Thnx in advance to all.

Hi Neeraj Sidhaye,
I am trying to deploy a sample xform application to the Oracle Application Server (10.1.3). However, I encountered the class loader issue that is similar to your stuation. I tried all the three solutions but the application is still use the Oracle xml paser class. I am wondering if you have any insight about this?
Thanks for your help.

Is it possible to display a date as (DD-MON-YYYY) in excel output using excel template in xml publisher

Is it possible to display a date as (DD-MON-YYYY) in excel output using excel template in xml publisher where date should be displayed as date only not string.

I've tried to use hierarchy node variables, but it seems like you can't specify a attribute of the hierarchy such as level. So with the WBS hierarchy, if you create a hierarchy node variable, you specify the WBS value to select (If I understand this correctly). I wish I could instead specify "give me all the WBS nodes that happen to have the value of the level attribute greater or equal to 3. If I understand Juergens post, he is saying make security access so that only certain WBS levels can be returned in the query. I suppose we can try that, but that would then preclude getting the level 1 and 2 in the future if the authorization is global.

Post XML over HTTPS in a loop

HI,
I have a requirement to post XMLs over HTTPS. I also am supposed to retrieve the response XML, interpret it and do some processing based on the response status in the response XML. This has to be done for each XML.
Currently I am establishing a new HTTPsURLConnection for each XML, wrting the XML to output stream, retrieving the response from input stream and then releasing the connection using disconnect() method.
Is this the recommended approach or should I be creating just one connection for posting all the XMLs? Also, does java use some kind of connection pooling while creating HTTPURLConnection?
I am frequently getting "SocketTimeoutException Exception --> connect timed out" while processing large number of XMLs. Is this exception due to large number of connections that I am creating?
This program is running as a stand alone program on unix box.
Regards,
Jacob

Is this the recommended approachYes.
or should I be creating just one connection for posting all the XMLs?No.
Also, does java use some kind of connection pooling while creating HTTPURLConnection? Yes.
I am frequently getting "SocketTimeoutException Exception --> connect timed out" while processing large number of XMLs. Is this exception due to large number of connections that I am creating?Could be, especially if you're doing them in parallel.

Urgent :post xml for xsql difference with html form post

Hi,
We are developing an application to process xml request
posted by external party. The requests arrive by
http-post operation
We developed and tested with an html-form.
Now we encounter problems in testing with http-post
The xsql page is processed correctly but
insert only fixed text when formatting xml-data as input for
the insert-request, string inserted is empty.
Everything is by the book and html-forms works great.
Is anybody else using xsql to insert xml data in the database on this version? Maybe can you help by looking into a testcase ? Issued a tar but am on terrible deadline
so need help very soon.
Details: HP-UX 11.11 Oracle 9.2.0.4 java1.4 ojdbc 1.4
Tnx in advance,
Jeroen

Mark,
Have an external partner which sends xml-requests.
Have to read those, store them and process them.
Idea is let them
1)post the xml at a url where an xsql page is reading the xml
2) transforming this for an insert into
the database. The column is defined to store the complete xml-message.
3) A trigger takes care of processing the stuff and preparing the output
4) and a query in the xsql-page reads the output from an output table
When developing and testing this with an html-form that posts the xml is works great.
$ cat newclobins.xsql
<?xml version="1.0"?>
<page connection="demo" xmlns:xsql="urn:oracle-xsql" >
<xsql:set-session-param name="id">
select msgid.nextval from dual
</xsql:set-session-param>
<xsql:dml>
delete cbs_msg_in where id={@id}
</xsql:dml>
<xsql:insert-request table="cbs_msg_in" column="id,msg" transform="cbsform_1.xsl"/>
<data>
<xsql:query null-indicator="yes">
select msgid,msg from cbs_xml_out where msgid={@id}
</xsql:query>
</data>
</page>
$ cat cbsform_1.xsl
<?xml version="1.0"?>
<ROWSET xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xsl:version="1.0">
<xsl:for-each select="request">
<ROW>
<MSG><xsl:value-of select="parameters/doc" /></MSG>
<ID><xsl:value-of select="session/id" /></ID>
</ROW>
</xsl:for-each>
</ROWSET>
1) When using a tool like
http://www.programmersheaven.com/articles/adrian/getpost/article.html it fails with
No rows to modify -- the row enclosing tag missing. Specify the correct row enclosing tag.
2) When using the commandline utility like
xsql jeroen5.xsql posted-xml=test3.xml
this works great when inserting plain text but not
when inserting xml-format data into a column
So problem 1 is why external tools like above or my partner that uses .net to do something similar gives this strange error?
Problem nr 2 is should I stick to just the data in xml and forget about storing the xml-formatted data?
Hope you can help because I am getting quite desparate here.
Regards,
Jeroen

How to post xml - request in mapviewer

Hello,
i want to make a web page that will post xml - requests in mapviewer.
How can i send a xml request in mapviwer from a web page?

Does the mapviewer welcome do what you need?
That is index.html in oc4jhome/j2ee/home/applications/mapviewer/web/
If it does then , use the same method to submit a form using HTTP POST to
the mapviewer servlet.
It's also documented in Ch 3 of the the user guide.
"A request to the OracleAS MapViewer servlet has the following format:
http://hostname[:port]/MapViewer-servlet-path?xml_request=xml-request

Posting XML to XSQL servlet

Hi
I use Java to post an XMLDocument to the XSQL servlet
my java program :
public void envoie() throws java.lang.Exception {

Off topic: posting XML/HTML in these forums

How do you post XML to these forums? Encoding the < as > just gets interpreted as a literal, but using straight XML doesn't work because if there's overlap with HTML, the XML gets formatted as HTML. Here's an example -- if you have an XML tag called "s" (< s n a m e = " f o o " > b a r < / s > ), look what happens (because of the strikethrough HTML tag): <s name="foo">bar</s>.
Sorry to post off-topic!
Chris Bucchere | bdg | [email protected] | www.bdg-online.com

Hello red_menace,
Indeed a pre-processing code like yours is always an option for us, but from my point of view, the correct solution is for the discussions' admins to disable this meddlesome formatting feature of the new fora software.
This new feature affects not only new posts but also the existing messages in the fora, that means it has rendered quite a few useful messages totally useless. This is actually serious data loss caused by the thoughtless software. And for what?
After all, these discussions' boards are not chat rooms where people might want some simple input methods for fancy text formattings, but technical support fora where people frequently post programming codes, computer outputs and so forth that have many reserved symbols and notation.
I really wish they may fix this promptly.
Best regards,
Hiroto

Using HAL to generate XML files

Greetings, I'd like to use HAL to build XML files and feeding certain variables while these files are generated. When the XML file is done being created, it will contain the variables passed. There are over 500 XML required to be build and for each of these files, only 2 or 3 variables must be passed to them. A template of the xml file was created using the Batch scheduler from Hyperion Reports, and this is the file I'd like to use as a template and build a HAL adapter based on that file. Does any one have a sample of the XML adapter (via screen shot) that I can use a starting guide? Many thanks in advance for your time.

Hi,
I'm running into the same problem deploying the classes generated by the class generator. Code works fine from JDeveloper, but had to put my DTD in the directory where my classes are. Deploying the classes with Apache's JServ gives me a NullPointer exception on the first addNode method. I guess it can't find the DTD. I tried to put the DTD in many locations but this didn't fix the problem. Any suggestions?
Steve,
Did you fix this problem? Thanx!

For the last 5 years (and in IPCC3.x/4.x,UCCX/5.x/7.x) I've used the same basic subflow to read a XML document that contains holiday dates where the queue should be closed. I've re-used this script on 20+ client installs and it's always worked. The structure of the script allows you to pass the path and filename of the XML document as parameters to the subflow. (The document is in the repository)
I loaded this script in UCCX 8.0.2 recently and it crashed with a Java.IO error. It looked like it was trying to read the file system directly and not the repository. (In the Linux appliance model this kind of makes sense but why is the step trying to read the file system directly?)
So I open a TAC case (SR# 615243125) and TAC tells me that the method of using the Create File Document step is not supported anymore and that I should specify the filename directly in the Create XML Document step
The problem that I see (aside from having to edit all my scripts that use XML files) is that the Create XML Document step is looking for the input to be a type DOCUMENT and not a type STRING. This seems to imply that I have to hardcode the document in each script that I deploy for a customer. When it was a string it was easy to construct the full file path from parameters and pass to the subflow.
Questions to the group
#1 Am I missing something here?
#2 Do you assume that you'll be able to load a script that worked fine in UCCX 7 into UCCX 8 and that it should completely function when you're doing everything according to the step reference documentation.
#3 Cisco didn’t document this in any way that I can find.
#4 How can you use the Create XML Document step in a fashion that would let you construct the path of the file and the filename previously in the script so you could pass it to a subflow ? It would seem this functionality has been killed in UCCX 8

The create XML document input can only be a type DOCUMENT

#1 Am I missing something here?
You are mixing two different issues together here.
The Create File Document step is indeed not needed or supported for creating an XML document. That is why there is a unique step; to trigger XML parsing within the MIVR subsystem.
Accessing the file system is restricted to a single folder within the VOS model (i.e. 8.0+). This folder is not backed up, replicated, or cleaned up automatically. It was intended to give developers some FS access as a temporary swap location only.
#2 Do you assume that you'll be able to load a script that
worked fine in UCCX 7 into UCCX 8 and that it should completely
function when you're doing everything according to the step reference
documentation.
Assume nothing; read the documentation and attend one of the dozens of partner training sessions that CCBU put on advising of the upcoming changes.
#3 Cisco didn’t document this in any way that I can find.
You're right, I guess, on the Create File vs. XML Document step. AFAIK Cisco never wrote a notice into the Step Reference Guide explicitly stating that you cannot use the Create File Document although the documentation seemed pretty clear to me without it. File system restrictions are documented in the 8.0 release notes.
Scripting and Development Series: Volume 2, Editor Step ReferenceUse the Create XML Document step to create a logical document that maps a document to another document variable (where the document has already been pre-parsed as an XML document and is ready to be accessed by the Get XML Document Data step).Use this step before the Get XML Document Data step to obtain data from a document formatted using the Extensible Markup Language (XML).
#4 How can you use the Create XML Document step in a fashion that would
let you construct the path of the file and the filename previously in
the script so you could pass it to a subflow ? It would seem this functionality has been killed in UCCX 8
No it hasn't; just concatinate a string to build the Source Document parameter the step needs. Example: "DOC[" + myFilePath + "]"
