Getting null for getRealPath.

Hi All,
Having 'resources' folder under WEB-INF folder, whiile trying to get RealPath it is returning 'null' value in basePath variable.
       HttpSession session = (HttpSession) FacesContext.getCurrentInstance().
                                                                getExternalContext().getSession(true);
        String basePath = session.getServletContext().getRealPath("/WEB-INF/resources");
Please let me know how to get real path in JSF.
Thanks,
Sharath.

It's an appserver thing. It will return null when the WAR is not extracted and also in some Weblogic configs/environments it will always return null regardless of WAR setup. This is not related to JSF.
Not related to your actual problem, but just a cosmetic hint, the getSession(true) is superfluous with a hardcoded boolean "true", just use getSession(). Further on, instead of HttpSession#getServletContext(), you can also get the ServletContext directly by ExternalContext#getContext().

Hi Hamendra,
Even after hard coding DestinationService.JNDI_KEY to tc~sec~destinations~service in the code, I am getting dstService = null.
Is there anything else I need to change in SAP portal NWA?
Is there any way to check the destination services that are available in SAP Portal?
Thanks

Get null for OTNDeptEmp DEPT/EMP Live Web Service

Using Oracle 9i JDeveloper Vers. 9.0.2.829. Has anyone successfully run this live web service with a proxy?
I made the changes to OTN.DeptEmpStub for proxy but when I run Class1.java the returnVal for getDeptNoArray is null
so I assume I'm not getting out our firewall or back through? Is there any way to test to see how far I'm getting or any clues as to
what is wrong??? I eventually get this error --- java.lang.NullPointerException

Getting null value for inputfile component in the popup

Hi,
My requirement is when i select the selectBooleanCheckBox a popup has to be rendered and with in that popup i have to display the inputfile component when i browse it should read the appropriate file.
But i am getting null from the input file component.
I written the code like this:-
1.First i have written a value change listener for the selectBoolenCheckBox.
2.I am rendering the popup from the valueChageEvent.
3.And i written the dialogListener for the Dialog in the popup.
and the code for the Dilog listener is:--
public void readingInputFile(DialogEvent dialogEvent) {
inputFile1.getValue();
//it is giving null value.
thanks in advance.
From
Srikanth.V

thanks for giving suggestion.
but i am not able to understand what meant by multipart in dialog page.
Actually,The code i written was:--
1. for selectBooleanCheckBox i written value chage listener
onChangeValue(ValueChageEvent valueChageEvent){
// in this i call the method to raise popup;
risePopUp();
2.The popup structure has follows:-
af:form --> af:popup ---> af:dialog --->af:inputfile
for this dialog i have written dilogListener:
getInputFile(DialogEvent dialogEvent){
//giving null for the inputFile,getValue();
for this dialog i don't have any multipart property
From,

Why am I getting the error "Coercion Failed: Input cannot be null for this coercion"?

I created a OOTB team site, with a OOTB document library and an OOTB "Approval - SharePoint 2010" workflow. Under the workflow's start options I have "Allow this workflow to be manually..." checked. On the next workflow setup page, I put
myself in the Assign To field and put "test" in the Request field. I left everything else blank.
Then, I setup a retention stage in the Information Management Policy settings for the library. The event is Modified + 1 days, action is Start a workflow and I selected the workflow described above. I set the Recurrence for 1 days.
If I execute the workflow manually, it executes without error.
When the IMP executes the workflow, the status indicated in the column added to the library is "Canceled". Clicking on the Canceled link opens the Workflow Information. In the Workflow History section the Event Type is Error, User ID is System
Account and Description is "Coercion Failed: Input cannot be null for this coercion".
Research shows that this error can be invoked when creating custom workflows that contain empty input fields when executed. I would think that if there were required input fields in the workflow
configuration, that the workflow would error when manually executed.
Any help is appreciated. Thank you.
Matt H.

I had found that article previously but it doesn't seem to apply since this is OOTB and not a workflow created in SD. I would expect that MS would have created the workflow in such a manner that it would work with IMP. Besides, I don't think
it's possible to edit the default Approvers workflow. Also, I'm sure I'm not the first one out there to use the Approvers workflow with IMP. If it was broken OOTB, someone else would have discovered it. My guess is that there is something
not configured correctly on the server, but I don't know how to start to diagnose it based on this error message.Matt H.

Reading and writing to file , getting null when i try to read file content

i start by apologizing incase i have posted this question in the wrong forum
i am trying to iterate through a directory tree and pick all the subdirectories and put them in an arraylist . on the other hand , i am picking all the files and putting them in a different arraylist . After that i iterate through the arraylist , pick a folder , create a file in it search for all the files of the same type in its subfolders and write them to the newly created file
The problem i am running into is i i can't read the files and hence i can't write to the file .
My directory tree is in the format
c:\KPCData\\01\01\01\01\01\ file1_type1
c:\KPCData\\01\01\01\01\02\ file2_type1
where one one of the types is "covers" . i know this could be asking too much but i am at my tethers end , could someone please have a look at the code and tell me where i might be going wrong . you could zero in on the part where i have ************ before the a line of code thank you package directories;

The problem i am having is that whereas i am very sure that there are contents in the files i am trying to read , this part of the code Print the Values of parentPath,directory.getParent() and file.getName() here .In the start of this if condition to get a idea what stuff is coming here.
if (parentPath.toString().compareTo(directory.getParent())==0&file.getName().contains("cover"))
               {Are you trying to compare parentPath and directory.getParent() as Strings ? How about using equals() ?
Also are you aware that a single & and && are not one and the same ?
& will check nevertheless even if the string comparison on the parentPath returns true or false.

never gets executed executed (meaning ,according to the code, the files am reading have no content ). i am a bit new to files and directories in java . i am hence seeking advice on what i could be doing wrong .IN short,debugging your code will help you a lot.

Getting null values from nodes using DOMParser

Hi
I'm having problems retrieving the values from an XML doc.
I'm using the DOMParser, but instead of retrieving the values
from the nodes, I just get null.
Code fragment :
DOMParser parser = new DOMParser();
parser.parse(url);
XMLDocument doc = parser.getDocument();
NodeList nl = doc.getElementsByTagName("*");
Node n;
iNode = nl.getLength();
for (int i=0; i<iNode; i++)
n = nl.item(i);
String szNodeName = n.getNodeName();
System.out.print(szNodeName+ " (" );
System.out.print(n.getNodeValue()+")");
System.out.println();
The result is
course (null)
Name (null)
All the node names are correct, but the node values are NOT
displayed.
Any idea ?
Rodrigo
null

According to the DOM Level 1 spec, the "value" of an ELEMENT node
is null and the getNodeValue() method will always return null for
an ELEMENT type node. You have to get the TEXT children of an
element and then use the getNodeValue() method in the text nodes.

Weblogic JMS EJB : ThreadLocal access query : getting null in same thread

We have two applications(one is jms and other is ejb) on single instance of weblogic managed server.
On receving a new jms message the jms application call the ejb application by passing the new xml message.
ejb application creates a threadlocal object and allocated transaction id to this transaction. I want to access this transactionid(present in threadlocal) in my jms application. But i am getting null.
I believe i am in the same thread as i printing the thread number in the both the application log. I verified that same thread number was present for multiple messages
in both logs [Except if one scenario of thread pooling is present that when jms calls ejb it frees the thread(23) and when ejb completes its job if gives back the thread(23) to jms...but it resets thread local]
I need answer to following question
1. Why is my transaction id null when i access through jms application.
2. I believe i am in the same jvm instance.
3. I believe i am in the same thread instance...( looking at logs except if someone can tell me i am not.....)
4. Or if there is alternative solution to pick up threadlocal variable in my jms application.
JMS application is new application trying to connect to existing ejb application which had the thread local design and we want to use that existing architecture before we decide to change. We need the transactionid for log corelation.

I assume that either your JMS destination is backed by a database or your application is doing some database operations in the same transaction as the JMS send operation. I suspect that there is some kind of database maintenance process going on every night, which causes the database operations to be slow or not responding, which in turn causes the MDB transaction that the JMS send operation participates in to timeout.

Getting null value while parsing "XML String" with encoding WINDOWS-1252.

Hi,
when I am converting the Follwoing "xml string " to Document, I am getting the "null" as a document value.
    String strXML = "<?xml version="1.0" encoding="WINDOWS-1252"?>
                          <category name="SearchByAttributes" value="Search By Attributes">
                            <item name="ORDER_LINE_ID" description="Application Search Attributes" >
                               <attribute name="Sequence" value="0001"/>
                             </item>
                            </category>"
My "xml string" has the encoding vaule: WINDOWS-1252.
I am using the following code to convert the "xml string" to Document. I am getting the Document values as a "null" while converting the above "string xml"
        String strXML = //my above string xml.
        DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
        docBuilderFactory.setIgnoringElementContentWhitespace(true);
        docBuilder = docBuilderFactory.newDocumentBuilder();
        doc = docBuilder.parse(new InputSource(new StringReader(strXML)));
        System.out.println("doc value.."+doc)//I am getting null value for "doc".
Can anyone help me to resolve the issue.

System.out.println("Element Attibrute list....."+elementAtt);
//getting Element Attribute list as an...."null"(I am expecting output value object reference but it is printing "null"
(without the rest of the code, i'm guessing that) most likely you are grabbing the first child node of the item element. however, you are not accounting for some text nodes that are most likely in that list, like the whitespace between the item element and the attribute element. please go read some tutorials on xml, there are thousands of them out there, and they will answer all you initial questions much more efficiently than posting each step to the forums.

**URGENT** No getter method for property searchText of bean org.apache.stru

I'm implementing a query page as described in the HowTo ADF_ComplexMasterDetail.zip
When running the query page, I'm receiving the error:
javax.servlet.jsp.JspException: No getter method for property searchText of bean org.apache.struts.taglib.html.BEAN
I have my searchEmployees writen and 'exposed' (at least I can see it in the Data palette). But seems like something is missing, and can't find this searchText beam property specified in the html:text tag.
Can someone help in this one?
Here is the Help description inside the HowTo example:
Section 3
queryEmployees
queryEmployeesInDept provides an interface for entering a simple search criteria for querying a list of
employees. This does not use the Find mode Query By Example functionality that the other query screens
use, but rather presents a much simpler search interface. The actual search is carried out using a
function
searchEmployees that the underlying view object exposes. (See the EmployeesView view object in the
model project)
1. Drop a new Data Page onto the page flow diagram call it queryEmployees
2. In the page flow diagram, drag the searchEmployees operation from the AllEmployeesView
collection in the Data Control Palette and drop it on top of the new Data Page. This will cause the
framework to run a search whenever the page is called.
3. In the Structure pane, locate the queryEmployees node and expand it, select the child node
paramNames[0], and change it's value attribute to ${param.searchText}. This will pass the URL
parameter searchText on to the business method to qualify the query.
4. Drill down into the page and expand the Data Control Palette to select the AllEmployeesView
collection. Set the Drag and Drop as: list to Read-OnlyTable. Then drag the collection onto the page.
This will create a tabular containing the query results.
5. Select the Struts HTML component palette and drag a Form onto the page above the output table. Set
the handling action to this Data Page (queryEmployees.do)
6. Drag a text field from the component palette inside of this new form. Set the property attribute of
the
<html:text> tag to searchText (the same value you used in the paramNames[0] for the Data Page)
7. Create a new submit button in the form to submit the search. Set the property attribute of the button
to
event_search.
8. Finally we need to subclass the data page to prevent the search action from being fired when it is not
appropriate for the page ( for instance when we first display it). To do this we need to Go to Code on
the Data Page's context menu, and override the invokeCustomMethod() method:
* We only want to invoke the custom method i.e. the call to change
* the Where clause on the collection, if the Action has been called with
* a search event on the page with a search term supplied.
* If the user got here via a link or another event, we bypass the model call
* unless a URL parameter event=search is supplied, in which
* case the method will also be called.
protected void invokeCustomMethod(DataActionContext actionContext)
List events = actionContext.getEvents();
// If the event is "search" do the custom event call
if ((events != null) && (events.contains("search")))
String searchTerm = (String)((DynaActionForm)actionContext.getActionForm())
Get("searchText");
if (searchTerm != null)
super.invokeCustomMethod(actionContext);
}
