NULL pointer exception when you use the tag ahref

Hello
I am writing a file html for the file adapter. Inside the transformation, if I understand ahref* tag, I still get null pointer exception and a 0 KB file is written.

However, if I remove the < a href > tag from the code, the html file is generated correctly. But I need to use ahref* tag. Pls help me solve this.
The details of the error are:

< bindingFault xmlns = "http://schemas.oracle.com/bpel/extension" > < a name = "summary" part > < summary > file:/opt/aia/product/10.1.3.4/OracleAS_MW/bpel/domains/release2/tmp/.bpel_OA_OUT_BPEL_MiddlewareEmailProv_1.0_734ff6b91af23ed1de9191df79ca28b6.tmp/in_Confirmation_FileWrite.wsdl [Write_ptt::Write (ORDER)] - SISM JCA Execute of 'Write' failure due to operation: null; nested exception is:

Hello
The custom XSD file is not necessary.
Looks like it's a bug in file 10.1.3.4/10.1.3.5 adapters - it works very well in 11g.

Whenever there is "a href" tag in the xml support to write to the file, the file adapter tries to get the content of the url real in 'a href' and written to the output file. When I try with any url (say http://www.google.com), the content of google.com is written in the file. If this URL is not accessible (for example http://foo.bar), then you get the null pointer exception. In your case, I think the URL that you are using the payload, is not accessible from your box of soa, or is not a valid URL.

As a work around 10.1.3.4, I was able to create the XHTML file as follows:
1 change the link partner of file adapter to use opaque scheme.
2. in an assign operation, affect the load XHTML to a string variable using ora:getContentAsString ().
3. Add a java embedding base64 encode the string as follows and assign to the entrance of the file adapter invoke:
(HTMLString is the string from step 1 variable, InvokeWriteHTML_InputVariable is the input variable to the call on the file adapter operation)

    
    
      
    

4. call the file adapter using the input variable in which is written the value encoded in base64.

you could use the workaround above or rethink your design (if you want to create the XHTML file using bpel only or other means).

Hope this helps,
Kind regards
Yohanna.

    I did not something outside the given procedure. I can tell everything is fresh on my JDEV as in $JAVA_TOP. But I'm, I was wondering why this page points to NULL Pointer Exception to NegotiationCreationAMImpl on JDEV however its fine on the side of the demand for labour. Its very strange. At the same time I also put my profile option "Sign-On: Notification ' on 'no '. I removed '-' DBC files too. But nothing could serve my purpose. Can you please help to solve this problem?

    Hoping for your reply.

    Thank you
    Sunil

    I'm assigned to a task where I need to change the query LOV to the field of legal entity on the request of QUOTE-negotiations page.

    There is no need to run the page locally. As there could be other files also that your page to be referred by any other top.

    What you need to do, is extend the controller or the VO and validate query LOV.

    Thank you

  • Error returned (sometimes) when you use the tag &lt; cfxml &gt;

    I have a problem when you use the < cfxml > tag, its seems error when I try and view the XML over a certain length, because it works for some of my folders and others do not.  Is there a known displaying stuff in the cfxml tag size limit?

    Here is my code, I don't know how to move forward on this issue. Well, any help would be apprciated.

    Right.

    It is therefore being truncated when it is read in the DB.  Nothing to do with CFXML.

    Looks like it is hitting the size of the Long text buffer (which by default is 64 KB).  Increase this value (in your DSN settings, advanced).

  • NULL pointer exception when you try to navigate to the next record

    Dear members,

    I have an OFA Page for which I have attached a CO and I am.

    This OAF page main and detail records.

    Main folders are coming from an array of headers. Detail records are coming from an array of LINES.

    Once the page opens, a master record and its corresponding detail records are displayed. On the page that I have a next button.if that user clicks the next button, next master file and its corresponding detail records should appear.

    The code I wrote is satisfying the requirement above but when the user comes from the last record and click on the next button, an EXCEPTION of the NULL POINTER is thrown.

    Code in my AM is as follows:_


    Public Sub findNextRec()
    {
    String headerID = null;
    If (Headers_VO1 () .getFetchedRowCount () > 0)
    {

    headerID = getHeaders_VO1 () .next ().getAttribute("HeaderId").toString ();
    If (headerID! = null & & "".equalsIgnoreCase (headerID))
    {
    getLines_VO1 (.setMaxFetchSize(-1));
    getLines_VO1 () .setWhereClause (null);
    getLines_VO1 () .addWhereClause ("header_id in (: 1)" ");
    getLines_VO1 () .setWhereClauseParams (null);
    getLines_VO1 (.setWhereClauseParam(0,headerID));
    getLines_VO1 () .executeQuery ();
    }
    }
    on the other
    {
    throw new OAException (' to the last Record,"OAException.CONFIRMATION");
    }

    }

    _ Code in my CO

    In my co process form request, I have the following code:

    If (PageContext.GetParameter ("Next")! = null)
    {
    am.invokeMethod ("findNextRec");
    }

    Kindly please help me to solve this error. Thanks in advance.

    Arun,

    I don't know that you should get the error on line

    headerID = getHeaders_VO1 () .next ().getAttribute("HeaderId").toString ();

    To do this, divide the likme statement
    Line = getHeaders_VO1 () .next ();
    if(Row!=null)
    {
    headerID = row.getAttribute ("HeaderId") m:System.NET.SocketAddress.ToString ();

    Thank you

    Yes, the source for the GF tools is available, but unless you already know how to debug Eclipse plugins, it's a pretty deep rabbit hole.

    1. to help-> them to install the new software

    2. use http://download.oracle.com/otn_software/oepe/luna/ as the URL of the repository

    3 uncheck the box "group items by category.

    4. Select and install GlassFish Source tools

    Otherwise, try to create a skeletal project that reproduces the problem and send it to us for analysis. Of the stack trace, it seems that the problem is somehow related to the GF web application deployment descriptor, so be sure to preserve by a repro.

  • NULL point Exception when obtaining the user name

    Hello

    I'm getting NULL pointer exception when trying to get the user name when the page load.

    My code is as follows:

    I had imported the oracle.apps.fnd.framework.webui.beans.message.OAMessageStyledTextBean package

    In the controller under the proceesrequest, I wrote the following code

    String uname = pageContext.getUsername ();
    OAMessageStyledTextBean UN = (OAMessageStyledTextBean) webbean.findChildRecursive ("name");
    one. SetValue (pagecontext, uname);

    After doing that when I run the page I'm getting NULL pointer exception.

    Can someone correct me where I had gone wrong.

    Thank you.

    The error is on line 39 of your controller. First thing you should do to avoid this must include an audit non-zero.
    String uname = pageContext.getUsername ();
    OAMessageStyledTextBean UN = (OAMessageStyledTextBean) webbean.findChildRecursive ("name");
    if(un!=null)

  • Move the point of origin when you use the scale tool

    Hello

    Can someone tell me if it is possible to move the point of origin when you use the scale tool? By default, when I change by dragging an anchor of the corner, the opposite corner is used as the origin. Ideally, I would like to to scale using an origin that is biased, I can specify sort. I know that you can do during the rotation, but I was not able to determine if this goal is achievable during the measurement. I use Illustrator CC 2015.3.1 and Mac.

    Any help would be appreciated.

    Thanks in advance

    Jason

    Click where you want the origin to be. Or move the reticle. Exactly the same as with the rotation tool.

  • When you use the pen tool when I click and create an anchor point and release the mouse button the pen tool emerges from the anchor and allow me to go and select a new anchor point. The right pen tool keeps adding lines that I move the mouse.

    When you use the pen tool when I click and create an anchor point and release the mouse button the pen tool emerges from the anchor and allow me to go and select a new anchor point. The right pen tool keeps adding lines that I move the mouse.  How can I get the pen tool to release the anchor

    Try this.go in the menus. Select cc illustrator > preferences > display selection & anchor > then make sure the box "activate the rubber band for" the pen tool is not selected. Then press OK. It should work.

  • Satellite L40 crashes when you use the product recovery disc

    Some may help how to solve the problem.

    Perhaps, your recovery disk is corrupt. What happens if you try with Windows disk copy?

  • Loop Finder crash after upgrading to El Capitan.  'Finder close unexpectedly when you use the plug-in finder' - the message really is in Norwegian, so it may be different for the English operating system.

    'Finder close unexpectedly when you use the plug-in finder' - the message really is in Norwegian, so it may be different for the English.  The e is a compatibility issue with dropbox or Google drive in El Capitan?  Those are the plug-ins only that I could find.  Thank you very much.

    Please launch the Console application in one of the following ways:

    ☞ Enter the first letters of his name in a Spotlight search. Select from the results (it should be at the top).

    ☞ In the Finder, select go utilities ▹ of menu bar or press the combination of keys shift-command-U. The application is in the folder that opens.

    ☞ Open LaunchPad and start typing the name.

    Step 1

    For this step, the title of the Console window should be all Messages. If it isn't, select

    SYSTEM LOG QUERIES ▹ all Messages

    in the list of logs on the left. If you don't see this list, select

    List of newspapers seen ▹ display

    in the menu at the top of the screen bar.

    In the upper right corner of the Console window, there is a search box to filter. Enter the name of the application crashed or process. For example, if Safari has crashed, you would enter "Safari" (without the quotes).

    Each message in the journal begins with the date and time when it was entered. Select the messages since the time of the last fall, as appropriate. Copy to the Clipboard by pressing Control-C key combination. Paste into a reply to this message by pressing command + V.

    The journal contains a large amount of information, almost everything that is not relevant to solve a particular problem. When you post a journal excerpt, be selective. A few dozen lines are almost always more than enough.

    Please don't dump blindly thousands of lines in the journal in this discussion.

    Please do not post screenshots of log messages - text poster.

    Some private information, such as your name, may appear in the log. Anonymize before posting.

    Step 2

    In the Console window, clear the search box, and then select

    DIAGNOSIS AND diagnostic USE information reports ▹ user

    (not diagnose them and use Messages) in the list of logs on the left. There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points downwards. You will see a list of reports of incidents. The name of each report begins with the name of the process and ends with ".crash". Select the most recent report on the process in question. The content of the report is displayed at right. Allows you to copy and paste to validate all of the content, text, not a screenshot.

    I know that the report is long, perhaps several hundred lines. Please report all this anyway. If the report is only a few lines, make sure that you have disabled the search box.

    If you don't see any report, but you know, he had an accident, you have chosen diagnostic and using the list of Log Messages. INFORMATION on the USE of DIAGNOSTIC AND choose instead.

    In the interest of privacy, I suggest that, before posting, you change the UUID ' anonymous, ' a long string of letters, numbers and dashes in the header of the report, if it is present (it cannot be). "

    Please do not post other types of diagnostic report - they are very long and rarely useful.

    When you post the journal excerpt or the accident report, you might see an error message on the web page: "you have included content in your post that is not allowed", or "the message contains invalid characters." It's a bug in the forum software. Thanks for posting the text on Pastebin, then post here a link to the page you created.

    If you have an account on Pastebin, please do not select private in exposure menu to paste on the page, because no one else that you will be able to see it.

  • Screen resolution/size changes when you use the touchpad

    Bought Probbok 4530 s. Win 7. I continue to have the screen/print resolutiom size change when you use the touch pad. The pointer seems to 'paste' and then when I move it, the screen get is much lower or higher. I continually have to type ctrl + or - to get the size of the screen back to the 'normal '. Is this something to do with the settings for the touchpad or pointer? Its driving me crazy...

    Bruce

    Hell, I think that this is it... Pinch Zoom! I have disabled that, as well as the "allow the theme change mouse pointers" on the pointers tab. I'm playing with it now, and it seems to have solved the problem. I'll let you know if this isn't... Thanks for the great help, Dragon fur!

  • When you use the media player, it is possible to take a song that's already torn in our library and announced another song or part of the same song at the end? kinda like a mix.

    When you use the media player, it is possible to take a song that's already torn in our library and announced another song or part of the same song at the end? kinda like a mix.

    Windows Media Player is not a Publisher.

    You can use Windows Movie Maker to split
    and combine audio files, but it works better
    If they are in the. WMA format.

    Also the free Audacity software may be worth a try:

  • Cursor turns in a circle when you use the pen and Wacom Tablet?

    When you use the stylus and Tablet Wacom the cursor becomes a circle inscribed in a circle and use.

  • ORA-01789 - when you use the operator of TABLE and SEM_MATCH

    Client version: 11.1.0.7 on Windows 7 (32 bit)
    Server version: 11.2.0.3 on Windows 7 (64-bit)

    I am model prototyping a simple RDF, and I'm getting a ' ORA-01789: block has an incorrect number of columns in query results "when you use the SEM_MATCH with the SCOREBOARD operator.

    I can run this:
    select id, a.triple.GET_TRIPLE() from drik.rdf_data a
    and the first line is:
    (<http://www.ihc.com/drik/term#2>, <http://www.w3.org/2000/01/rdf-schema#subClassOf>, <http://www.ihc.com/drik/term#1>)
    Now, I want to use the TABLE like this:
    select
      c
    from 
      table(sem_match('{ <http://www.ihc.com/drik/term#2> <http://www.w3.org/2000/01/rdf-schema#subClassOf> ?c . }', 
            sem_models('Prototype'),
            sem_rulebases('RDFS'),
            sem_aliases(sem_alias('rdfs','http://www.w3.org/2000/01/rdf-schema/')),
            null
            ))
    But this performance gives the ORA-07189. Even try SELECT * gives the same error.

    I expect to get a refund:
    <http://www.ihc.com/drik/term#1>
    How should I approach troubleshooting this?

    Thank you, Steve

    Thanks for posting the script. I was able to reproduce the error locally.

    The problem is the use of the sem_apis.create_rules_index () procedure, which has been deprecated:
    http://docs.Oracle.com/CD/E11882_01/AppDev.112/e25609/sdo_rdf_newfeat.htm#autoId26

    Please use sem_apis.create_entailment () instead, and the error should disappear.
