I made a purchase with my debit card on The Simpson Tapped out game, And now my game won't open. It just kicks me out every time I click on it. How do I fix this problem with out deleting my app?

Personally, I would never use a debit card online, for security reasons. If your card gets hacked its your money that is stolen. At least with a credit card it is the card providers money that is stolen.
Anyway, I would delete the app and re-install. If you paid for the app in the first place you will be able to re-install free of charge. Also, the app should allow the in-app purchase to happen again as it should recognise that you have already purchased it previously.
Finally, it might be that the 3G doesnt have as much ram as more recent models of iphone and you may have applications running in the background that are preventing the app to function with the in-app purchase unless you shut down any apps eating all you memory that are running in the background. Shut-down these apps (and the simpson tap out app) by exiting to your home screen and double-tapping the home button to show what apps are running in the background. press and hold any of the open apps until it starts shaking. close all the apps down. exit then re-launch the app.
good luck.

Problem with Assign reference document.

Hi all,
I defined transaction input parameter type Xml.
I used Reference Document Loader to load document (structure.xml) below.
<?xml version="1.0" encoding="UTF-8"?>
<SO_VALIDATION>
    <L4_SO_ID/>
    <L4_SOI_NO/>
    <PPC_STATUS/>
    <PPC_INFO/>
</SO_VALIDATION>
I used menu command Assign Reference Document, to assign above document to transaction input.
I tryed to use this transaction in vs.net application as a web service.
But there is no xml structure in InputParams in web service.
I tryed alot but i did not achieve.
What must i do?
Thanks.

cml_bzl,
I'm using version 12.04 and I have not had any problems with assigning reference documents and using .NET.
You should not have to do anyting special to get the transaction inputs to show up in .Net. To map the output I do the following:
1. Create an output transaction variable and assign it's type as XML
2. Using a XML document block to create and XML document for your output transaction variable
3. Assign the XML document as the reference for the output transaction variable.
THis works for me every time. If you change the transaction parameters, make sure you update the web service form the .NET side.

Problem with out of memory and reservation of memory

Hi,
we are running a very simple java program on HP-UX that do some text substitution - replacing special characters with other characters.
The files that are converted are sometimes very large, and now we have come to a point where the java server doing the work crashes with "Out of memory" message. (no stack) when it process one single 500MB large file.
I have encountered this error before(with smaller files) and then I have made the maximum Heap larger, but now when I try to set it to 4000M
i get the message:
"Error occurred during initialization of VM
Could not reserve enough space for old generation heap"
When it crash with this message, my settings are:
-XX:NewSize=500m -XX:MaxNewSize=1000m -XX:SurvivorRatio=
8 -Xms1000m -Xmx4000m
If I run with Xmx3000m instead the java program starts but I get Out of memory error like:
java.lang.OutOfMemoryError
<<no stack trace available>>
The GC log file created when it crashes looks like:

We are running:
java version "1.3.1.02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1.02-011206-02:17)
Java HotSpot(TM) Server VM (build 1.3.1 1.3.1.02-JPSE_1.3.1.02_20011206 PA2.0, mixed mode)
We have 132GB of physical memory and a lot of not used Swap space, so I cant imagine we have a problem with that.
Can anyone please suggest what to do proceed troubleshooting or to change some settings? I'm not into this Java really so I really need some help.
Usually the java program handles thousands of smaller files (around 500 KB - 1 MB sized files).
Thanks!

You have a one to one mapping? Where one character is replaced with another?
And all you do is read the file, replace and then write?
Then there is no reason to have the entire file in memory.
Other than that you need to determine if the VM (which is not a Sun VM) has an upper memory bound. That would be the limit that the VM will not go beyond regardless of memory in the system.
We have 132GB of physical memory and a lot of not used Swap spaceOne would wonder why you have swap space at all.

          You realy can do it like Xiang says, but the better way is to use packages. That's
          the way BEA is designed for. If you use packages you can but your bean classes
          in every subfolder beneath Classes. Here for example we have the subfolders test
          and beans:
          You have to declare the package on top of your Bean Source Code:
          package test.beans;
          In your JSP you don't need the import code of Xiang. You only have to refer the
          path of your bean class:
          <jsp:useBean id="testBean" scope="session" class="test.beans.TestBean" />
          There are some other AppServers that only can deploy Java Beans in packages. So
          if you use packages you are always on the right side.

Problem with Type Reference "TYPE' in JCO

Hi All,
I am facing a weard situation when i am creating a custom RFC function module. This FM is called by Java program with JCO. But, if i define the FM parameters with Reference type as 'TYPE', the Java application is not able to get the data. But the same time, if i declare the parameters with 'LIKE', it is working successfully.
Can anybody advise me, why it is behaving differently? Is the problem with JCO which is not able to recognise the 'TYPE' reference or from SAP side?
And, any solution to use 'TYPE' reference successfully?

hi Sailesh,
You are right. SAP doesn't recommend the usage of Like in PROGRAMS/REPORTS - mind it, only REPORTS.
But when it comes to RFC enabled FMs, JCo Understands only LIKE. what you had observed is true. LIKE creates a WA and JCo looks into a workarea. TYPE can refer to a pool of variables but your JCo can't differentiate them. So, you use LIKE.
Again, you use LIKE only Remote enabled FMs not in Reports/Programs. so, you may use TYPE as your company remommends in reports but in RFMs, use LIKE.
Hope this cleared.
Regards
Ak.

Pls Help : Union with outer reference

Hi ,
I have a simple and but at the same time complicated problem with union in my query :
Please see below sql :
The inner query with union command can not access to the outer table task_history taskHistory
I receive below error message :
**"ORA-00904: "TASKHISTORY"."TIME_STAMP": invalid identifier**
**00904. 00000 - "%s: invalid identifier"**
***Cause:**
***Action:"**
would you please help me to find out what I am doing wrong?
thanks,
select
(select max(closerDate) from
select cast(max(time_stamp) as date) as closerDate
from task_history taskHistory_2, rx_tx rxtx_2

taskHistory_2.task_name IN('order_entry', 'data_entry', 'data_verification','fill','product_verification' )
and rxtx_2.rx_summary_id = 65656

Welcome to the forum!

Well the first thing you are doing wrong is posting in the wrong forum.
This is the SQL Developer forum and, as you can see from the title, is 'Not for general SQL/PLSQL questions'.
Please repost the question in the SQL and PL/SQL forum.
PL/SQL
When you post use \ tags on the line before and on the line after your code to preserve the formatting. See the FAQ for details.
You also need to provide your 4 digit Oracle version (result of SELECT * FROM V$VERSION) every time you post.

The inner query with union command can not access to the outer table task_history taskHistory
I receive below error message :
**"ORA-00904: "TASKHISTORY"."TIME_STAMP": invalid identifier**
{quote}
What else would you expect? The inner query has no knowledge of the outer query. How could it? The outer query doesn't exist until it processes both of the inner queries.
Each query of the union all needs to be a completely separate query. You should be able to run each query by itself and get a result set.
If you can't the query is invalid. Since the only table involved that has TIME_STAMP is the task_history table you need to use that table.

Problem with this piece of jsp

Hi,
I have a problem with this piece of code, and I dont know why is the error caused:
<% String value=(String)session.getAttribute("add");
*if (value.equals("add")) { * %>
<th>Add quantity</th>
<% } else { %>
<th>Modify quantity</th>
<% } %>
When I debug Apache Tomcat log gives me the NullPointerException error, in the line underlined in bold, but theorically if the sentence "if" is not true it should enter in the "else" part but it doesn`t do, and I dont have the explanation.
I would be very grateful if somebody could help to solve this problem.
Regards.
Edited by: user1577231 on 04-oct-2010 6:33

If you get a NullPointerException at that point, then that probably means that value is null.
The easiest way to avoid this NPE is to write "add".equals(value) instead.

Eclipse problem with Tomcat when running jsp

when I start tomcat from CMD, it starts normally and display http://localhost:8080/ properly
but when I start tomcat from Eclipse, it starts the server normally,
but it can't display http://localhost:8080/ properly,
I guess that the problem with the java classpath isn't defined correctly in Eclipse
but but I've tried it before, and it doesn't work
here the error msg from Eclipse console:

I would suggest updating your software to the latest versions - java 1.4.2 or higher, tomcat 5 or higher, Eclipse 3. That should fix any incompatibilities you are experiencing.
As to your problem, it seems the tomcat you are trying to run from Eclipse wants a newer Java version (1.4.2 most likely).

Problem with post and get (jsp to servlet)

===jsp code(login.jsp)
out.println("<form action='servlet/Login' action='post'>");
out.println("Username <input type='text' name='user' /><br>");
out.println("Password <input type='password' name='pass' /><br>");
out.println("<input type='submit' value='Login' /><br></form>");
the above jsp page is included in another jsp page
===jsp code(index.jsp)
<jsp:include page='login.jsp' flush='true'/>
when submit is clicked in the login form, the data is send (to Login servlet) in the url string, even though i am using "POST" method in the form.
the output of request.getMethod() in the Login servlet gives "GET"
what could be the problem?

The code you've shown us looks fine. The problem isn't in the form code you've listed. Is the form being included inside another form on index.jsp? Does index.jsp have any forms of it's own? Perhaps you aren't submitting the form you think you are submitting. Or, are you redirecting in your serlvet somewhere? Or are you forwarding the request somehow?
I agree with the previous post - we need to see the HTML output that index.jsp results in.

Problem with jni references

i have to implement a few standard APIs. As a part of the implementation I have to provide references to an object I create. Now my underlying code is C++ with JNI used to throw the Java APIs. Problem is JNI now returns different references for the same object and hence my prupose id defeated. Could anyone suggest how this problem can be overcome.

I'm not exactly sure what you're talking about, but it sounds like you may need to look into global references. Look at NewGlobalRef() and DeleteGlobalRef() and see if those help you out.
God bless,

Problem with file download through JSP under WLS6.1 SP3

Hello,
We're in the process of trying to migrate from WLS 6.1 SP1 to SP3, and we're encountering
some difficulties with this migration.
I'm attaching a very simple JSP here - it's a snippet from a larger more dynamic
JSP, that I managed to narrow down to a pretty simple case which still doesn't
work.
This JSP opens a file residing at "c:\\BDELog.txt" (it's hardcoded - so change
it to any textual local file on your machine in order to test it), and writes
it to the output stream as a txt attachment.
This JSP works perfectly well on SP1, however, on SP3, it fails only during the
first hit. If you call this JSP again from the same browser window - it'll work.
Needless to say - this isn't an acceptable behavior for a website.
Hope you can help.
Appreciate any response.
Roy.

SP4 indeed solved it.

Many thanks !! (sigh of relief...)
Is there a way to work around this problem - for example - write
the

so that the problematic header will be overriden or simply get a
patch
from you
guys ?
Or do we have to wait for SP4 ?
Thanks again,

"Eric Gross" <[email protected]> wrote:
This is a known issue and has been fixed.
The fix is in SP4. This has to do with a bug that IE has with respect
to a
header:
Cache-Control: no-cache="set-cookie"
We introduced that as the default header to be returned on all
responses.
As of SP4(due out very soon), the default behaviour will be notto send
this
header back with each response.
