Need help with transforming abap to xml doc!!

Abap To XML
Posted: Aug 18, 2005 11:31 AM Reply E-mail this post
I was able to transfer xml data from abap internal tables to a string.
Here is the content of the string:
<?xml version="1.0" encoding="iso-8859-1"?>
<asx:abap version="1.0" xmlns:asx="http://www.sap.com/abapxml">
<asx:values>
<DATA>
<item>
<UOM1 />
<UOM2>L</UOM2>
<GL_PR_SEG />
<RECORDMODE>A</RECORDMODE>
</item>
</DATA>
</asx:values>
</asx:abap>
Now my goal is to strip out a couple of tags out of that string directly using xslt.
Do you know of any way i could take out the <asx:abap> and <asx:values> tags using an xslt program. I'd like to be able to strip them out directly from the string itself.

Hi there,
Unfortunately this is a bit outside the scope of what ExportPDF is designed for. You may be able to convert your document to a Word file and, as long as you didn't write over any of the printed text on the document, make your edits there to remove your writing That said, it sounds like your best bet would be to scan the document to an image format, then use a photo-editing application, such as Photoshop Elements to touch up and remove your hand-written notes.
Please let us know if you have any questions.

Need Help With Simple ABAP Code

Hello,
I'm loading data from a DSO (ZDTBMAJ) to an Infocube (ZCBRAD06). I need help with ABAP code to some of the logic in Start Routine. DSO has 2 fields: ZOCTDLINX & ZOCBRDMAJ.
1. Need to populate ZOCPRODCD & ZOCREFNUM fields in Infocube:
    Logic:-
    Lookup /BI0/PMATERIAL, if /BIC/ZOCBRDMAJ = /BIC/OIZOCBRDMAJ
    then /BIC/ZOCPRODCD = ZOCPRODCD in Infocube
           /BIC/ZOCREFNUM = ZOCREFNUM in Infocube
2. Need to populate 0G_CWWTER field in Infocube:
    Logic:
    Lookup /BIC/PZOCTDLINX, if /BIC/ZOCTDLINX = BIC/OIZOCTDLINX
    then G_CWWTER = 0G_CWWTER in Infocube.
I would need to read single row at a time.
Thanks!

I resolved it.

Need help with generating keys from xml

Hello,
I am just learning about JCE and am haveing some problems with implementing a basic program.
I have the following information:
<RSAKeyValue>
<Modulus>Base64EncodedString</Modulus>
<Exponent>Base64EncodedString</Exponent>
Base64EncodedString
<Q>Base64EncodedString</Q>
<DP>Base64EncodedString</DP>
<DQ>Base64EncodedString</DQ>
<InverseQ>Base64EncodedString</InverseQ>
<D>Base64EncodedString</D>
</RSAKeyValue>
From which I need to construct a public and private key. I am using RSA algorithm for the encrypting and decrypting. I am using the org.bouncycastle.jce.provider.BouncyCastleProvider provider. Any help would be greatly appreciated.
My questions are:
1) Is it possible to create the public and private key from this data?
2) How can I construct a public and private key from this data.
Thank you in advance.
Sunit.

Thanks for your help...I am still having problems.
I am now creating the public and private keys. I am generating the public exp, modulus, private exp, and the encrypted text from another source.
so my questions are:
1) How do I verfiy that the private and public keys that I generate are valid?
2) How do I get the decrypted text back in a readable form?
3) the decrypted text should read "ADAM"
Here is a test I wrote:

Need help with Link passed from XML

This is to create a flash driven navigation menu. What I have
is a coldfusion page that serves a simple XML formatted page. There
are 3 XML components, linkLabel, linkURL and linkType. The label
just passes text, the type is just a number 0-9 that is used to
determine the style of the button. The linkURL that is passed from
coldfusion comes across encoded for XML, so what I end up with is
url's that replace "&" with ";amp;".
So my question is this, is there an easy way in the
actionscript to replace the ";amp;" with "&"? Other than that
little problem, the rest of the script runs just fine, I just can't
seem to find the syntax I'm looking for to replace items in a
string. I saw the code for replacesel() but this doesn't seem to do
it, unless i'm writing it wrong.

Just in case you want something similar in future:
string = string.split("&").join("&");
is an easy way to replace something in a string (here
'&' gets replaced with '&').

Need help with sun one and xml

I have installed the Java Web Services Developer Pack. I am also using Sun One ide. I am trying to import the dom package. When ever i use "import org.", in the Sun One ide to lookup the packages, no packages come up for w3c.dom. I have tried to just use "import org.w3c.dom;", but i get an error when i try to instantiate a DOMImplementation. The JWSDP says that you do not need to register any classpaths. Any help would be much appreciated.

I've noticed that no packages come up either.
Try:
import org.w3c.dom.*;
to import all the classes, or be more specific:
import org.w3c.dom.Node;
(this is better coding style as you know exactly what classes you are using)
Hope this helps

I need help with a question regarding XML

I have an exam tomorrow, and I was checking exams from previous years. There is a multiple choice question regarding XML, and I don't know all the correct answers (some are pretty obvious).
It's plattform independent
It allows UML representation
It's a Text Only format
It's faster to process than native binary formats
It's a data exchange standard
It allows specification of the meaning of the data in the document
It comes from HTML
.NET and J2EE provide tools to handle it

In the beginning there was SGML... the newest HTML
standard is an XML defined language (although most
sites and pages are still not XML compliant). Soyou
can think of HTML as a subset of XML but XML isnot
by any means a subset of HTML.But wasn't XML's format based on the original HTML?
That is, XML is a generalization of the original
HTML. So, the "true"/"false" determination depends
on how you define "It comes from HTML" (I thought it
was derived from HTML, which would make the
statement "true" [IMHO], but I could be wrong).No XML is not derived from HTML. Markup languages existed well before HTML. HTML popularized them to a large extent but it was not the first by any means.
See http://en.wikipedia.org/wiki/Generalized_Markup_Language
Also Wiki states in it's XML article that XML is a subset of SGML (which through that article) is a descendent of GML
The language heirarchy from SGML is as follows
SGML ---- HTML (old spec and deprecated)
       |
       |
       ----- XML ----- XHTML (current XML spec)edit: the tree got screwed up. XML descends from SGML directly.

Need help with erasing from a scan doc.

I have a bill I need to send to Medicare. I'm very bad about writing on every scrap of paper and I have mess this up. I scan and put it in an Adobe ExportPDF, which I thought I've done before to erase all my chicken scratchings,but It won't work. Am I in the wrong program or Was I dreaming?

Need help with Berkeley XML DB Performance

We need help with maximizing performance of our use of Berkeley XML DB. I am filling most of the 29 part question as listed by Oracle's BDB team.
Berkeley DB XML Performance Questionnaire
1. Describe the Performance area that you are measuring? What is the
current performance? What are your performance goals you hope to
achieve?
We are measuring the performance while loading a document during
web application startup. It is currently taking 10-12 seconds when
only one user is on the system. We are trying to do some testing to
get the load time when several users are on the system.
We would like the load time to be 5 seconds or less.
2. What Berkeley DB XML Version? Any optional configuration flags
specified? Are you running with any special patches? Please specify?
dbxml 2.4.13. No special patches.
3. What Berkeley DB Version? Any optional configuration flags
specified? Are you running with any special patches? Please Specify.
bdb 4.6.21. No special patches.
4. Processor name, speed and chipset?
Intel Xeon CPU 5150 2.66GHz
5. Operating System and Version?
Red Hat Enterprise Linux Relase 4 Update 6
6. Disk Drive Type and speed?
Don't have that information
7. File System Type? (such as EXT2, NTFS, Reiser)
EXT3
8. Physical Memory Available?
4GB
9. Are you using Replication (HA) with Berkeley DB XML? If so, please
describe the network you are using, and the number of Replica’s.
No
10. Are you using a Remote Filesystem (NFS) ? If so, for which
Berkeley DB XML/DB files?
No
11. What type of mutexes do you have configured? Did you specify
–with-mutex=? Specify what you find inn your config.log, search
for db_cv_mutex?
None. Did not specify -with-mutex during bdb compilation
12. Which API are you using (C++, Java, Perl, PHP, Python, other) ?
Which compiler and version?
Java 1.5
13. If you are using an Application Server or Web Server, please
provide the name and version?
Oracle Appication Server 10.1.3.4.0
14. Please provide your exact Environment Configuration Flags (include
anything specified in you DB_CONFIG file)
Default.
15. Please provide your Container Configuration Flags?
final EnvironmentConfig envConf = new EnvironmentConfig();
envConf.setAllowCreate(true); // If the environment does not
// exist, create it.
envConf.setInitializeCache(true); // Turn on the shared memory
// region.
envConf.setInitializeLocking(true); // Turn on the locking subsystem.
envConf.setInitializeLogging(true); // Turn on the logging subsystem.
envConf.setTransactional(true); // Turn on the transactional
// subsystem.
envConf.setLockDetectMode(LockDetectMode.MINWRITE);
envConf.setThreaded(true);
envConf.setErrorStream(System.err);
envConf.setCacheSize(1024*1024*64);
envConf.setMaxLockers(2000);
envConf.setMaxLocks(2000);
envConf.setMaxLockObjects(2000);
envConf.setTxnMaxActive(200);
envConf.setTxnWriteNoSync(true);
envConf.setMaxMutexes(40000);
16. How many XML Containers do you have? For each one please specify:
One.
1. The Container Configuration Flags
          XmlContainerConfig xmlContainerConfig = new XmlContainerConfig();
          xmlContainerConfig.setTransactional(true);
xmlContainerConfig.setIndexNodes(true);
xmlContainerConfig.setReadUncommitted(true);
2. How many documents?
Everytime the user logs in, the current xml document is loaded from
a oracle database table and put it in the Berkeley XML DB.
The documents get deleted from XML DB when the Oracle application
server container is stopped.
The number of documents should start with zero initially and it
will grow with every login.
3. What type (node or wholedoc)?
Node
4. Please indicate the minimum, maximum and average size of
documents?
The minimum is about 2MB and the maximum could 20MB. The average
mostly about 5MB.
5. Are you using document data? If so please describe how?
We are using document data only to save changes made
to the application data in a web application. The final save goes
to the relational database. Berkeley XML DB is just used to store
temporary data since going to the relational database for each change
will cause severe performance issues.
17. Please describe the shape of one of your typical documents? Please
do this by sending us a skeleton XML document.
Due to the sensitive nature of the data, I can provide XML schema instead.
18. What is the rate of document insertion/update required or
expected? Are you doing partial node updates (via XmlModify) or
replacing the document?
The document is inserted during user login. Any change made to the application
data grid or other data components gets saved in Berkeley DB. We also have
an automatic save every two minutes. The final save from the application
gets saved in a relational database.
19. What is the query rate required/expected?
Users will not be entering data rapidly. There will be lot of think time
before the users enter/modify data in the web application. This is a pilot
project but when we go live with this application, we will expect 25 users
at the same time.
20. XQuery -- supply some sample queries
1. Please provide the Query Plan
2. Are you using DBXML_INDEX_NODES?
Yes.
3. Display the indices you have defined for the specific query.
     XmlIndexSpecification spec = container.getIndexSpecification();
     // ids
     spec.addIndex("", "id", XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     spec.addIndex("", "idref", XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     // index to cover AttributeValue/Description
     spec.addIndex("", "Description", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ELEMENT | XmlIndexSpecification.KEY_SUBSTRING, XmlValue.STRING);
     // cover AttributeValue/@value
     spec.addIndex("", "value", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     // item attribute values
     spec.addIndex("", "type", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     // default index
     spec.addDefaultIndex(XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ELEMENT | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     spec.addDefaultIndex(XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     // save the spec to the container
     XmlUpdateContext uc = xmlManager.createUpdateContext();
     container.setIndexSpecification(spec, uc);
4. If this is a large query, please consider sending a smaller
query (and query plan) that demonstrates the problem.
21. Are you running with Transactions? If so please provide any
transactions flags you specify with any API calls.
Yes. READ_UNCOMMITED in some and READ_COMMITTED in other transactions.
22. If your application is transactional, are your log files stored on
the same disk as your containers/databases?
Yes.
23. Do you use AUTO_COMMIT?
     No.
24. Please list any non-transactional operations performed?
No.
25. How many threads of control are running? How many threads in read
only mode? How many threads are updating?
We use Berkeley XML DB within the context of a struts web application.
Each user logged into the web application will be running a bdb transactoin
within the context of a struts action thread.
26. Please include a paragraph describing the performance measurements
you have made. Please specifically list any Berkeley DB operations
where the performance is currently insufficient.
We are clocking 10-12 seconds of loading a document from dbd when
five users are on the system.
getContainer().getDocument(documentName);
27. What performance level do you hope to achieve?
We would like to get less than 5 seconds when 25 users are on the system.
28. Please send us the output of the following db_stat utility commands
after your application has been running under "normal" load for some
period of time:
% db_stat -h database environment -c
% db_stat -h database environment -l
% db_stat -h database environment -m
% db_stat -h database environment -r
% db_stat -h database environment -t
(These commands require the db_stat utility access a shared database
environment. If your application has a private environment, please
remove the DB_PRIVATE flag used when the environment is created, so
you can obtain these measurements. If removing the DB_PRIVATE flag
is not possible, let us know and we can discuss alternatives with
you.)
If your application has periods of "good" and "bad" performance,
please run the above list of commands several times, during both
good and bad periods, and additionally specify the -Z flags (so
the output of each command isn't cumulative).
When possible, please run basic system performance reporting tools
during the time you are measuring the application's performance.
For example, on UNIX systems, the vmstat and iostat utilities are
good choices.
Will give this information soon.
29. Are there any other significant applications running on this
system? Are you using Berkeley DB outside of Berkeley DB XML?
Please describe the application?
No to the first two questions.
The web application is an online review of test questions. The users
login and then review the items one by one. The relational database
holds the data in xml. During application load, the application
retrieves the xml and then saves it to bdb. While the user
is making changes to the data in the application, it writes those
changes to bdb. Finally when the user hits the SAVE button, the data
gets saved to the relational database. We also have an automatic save
every two minues, which saves bdb xml data and saves it to relational
database.
Thanks,
Madhav

Could it be that you simply do not have set up indexes to support your query? If so, you could do some basic testing using the dbxml shell:
milu@colinux:~/xpg > dbxml -h ~/dbenv
Joined existing environment
dbxml> setverbose 7 2
dbxml> open tv.dbxml
dbxml> listIndexes
dbxml> query     { collection()[//@date-tip]/*[@chID = ('ard','zdf')] (: example :) }
dbxml> queryplan { collection()[//@date-tip]/*[@chID = ('ard','zdf')] (: example :) }Verbosity will make the engine display some (rather cryptic) information on index usage. I can't remember where the output is explained; my feeling is that "V(...)" means the index is being used (which is good), but that observation may not be accurate. Note that some details in the setVerbose command could differ, as I'm using 2.4.16 while you're using 2.4.13.
Also, take a look at the query plan. You can post it here and some people will be able to diagnose it.

I need help with XML Gallery Fade in out transition. somebody please help me
I have my post dont want to duplicate it

The problem doesn't lie with your feed, although it does contain an error - you have given a non-existent sub-category. You need to stick to the categories and sub-categories listed here:
http://www.apple.com/itunes/podcasts/specs.html#categories
Subscribing to your feed from the iTunes Store page work as such, but the episodes throw up an error message. The problem lies with your episode media files: you are trying to stream them. Pasting the URL into a browser produces a download (where it should play the file) of a small file which does not play and in fact is a text file containing (in the case of ep.2) this:
[Reference]

Need help with almost completed plugin engine project

Hi all,
For a while now I have been working on a plugin engine. After a few iterations, the engine is similar to the Eclipse engine, in that plugins use extension points and extensions to allow contributions. Unlike the eclipse engine I have added the ability for plugins to fire events through the engine and other plugins can add listeners, all through the plugin.xml manifest. Dependencies are mostly handled automatically at plugin load time (when extensions get resolved to extension points, and listeners get resolved to events). For the case where a plugin needs to use classes from another plugin, dependencies are also allowed to be declared. Like the eclipse engine, activation of plugins occurs the first time a class is used within the plugin's classpath, OR a plugin can be activated after it is loaded.
What I need help with is testing, working on examples to provide with the engine project, and feedback/suggestions before we release the M1 build. I am asking for those that are interested in this type of work to volunteer to help where applicable and possible. I want to provide a solid plugin engine to the java community, one that is easy to use, works well, and is pretty effecient in terms of resource usage and performance.
Of particular interest to me right at the moment is dealing with multiple versions. As I see it, the engine will be used within an application and as such plugins would be distributed with a specific application version. The plugin version itself is more of a notification as to what version a plugin is, although I imagine it will help when updating at runtime as well.
Just a few other details of the engine. It handles (or will soon) dynamic load, unload and reload of plugins at runtime. Plugins can be distributed in an archive file format, we call .par (Plugin ARchive), with additional plugin filename extensions configurable at runtime. The plugins can be developed and deployed in an expanded directory format as they are in Eclipse as well, or in the archive format. In the archive format they do not need to be unzipped when deployed, and they can contain embeded jar/zip libraries. The engine handles finding and creating classes directly out of the .par file at runtime.
Multiple locations to find plugins are configurable before the engine starts, and even after it starts more could be added to allow additional locations to find plugins. URLs are supported, and soon the HTTP protocol will be supported so that plugins can be downloaded and installed at runtime.
The project can be found at www.sourceforge.net/projects/genpluginengine. If you would like to get involved and help out, please sign up on the dev mail list and send an email to introduce yourself to the rest of the members on the list.
I'll also add that I am working on a Swing UI Framework built entirely from plugins. It provides a ready-to-launce UI application that developers can simply add their plugins to, extending various extension points of the framework to have menu items, toolbar buttons, status bar access, help and preferences dialog additions, file i/o choosers, tons of open-source components ready to use (or extend to add on to), and like Eclipse, hopefully... draggable window frames that can be dropped on any other frame to form a tabbed frame of windows. Some of this is a ways off, some is getting there now. Presently you can add menu items that do allow plugin activation when first clicked, so plugins can be loaded but not activated until needed. The Preference dialog works but is not completed, and a plugin that adds a plugin control panel to view all loaded plugins, activate them, load/unload/reload, view extension points, extensions, dependencies, etc is partially completed. The point is, to allow a ready to run UI framework in Swing with an easy path for developers to quickly build applications with. If you are interested in this, when you join the mail list and introduce yourself, indicate that you are interested in this as well, as we need help with plugin development for it and would appreciate more help here too.
Look forward to some replies.

Might I suggest setting up a project at a known project-site? I've seen your progress and questions posted here from time to time, but one of the drawbacks is that you have to fill each post with the entirity of your vision to explain what you're doing. That's a lot of text to read - and most folks will skip right over it.
On the other hand, a well-crafted, good-looking project web-site, with appropriate links and docs and vision statements, diagrams, etc. will have more likelyhood of attracting volunteers. java.net and sourceforge.net are likely spots to set up shop. In addition, you get CVS and bug-tracking systems, which can be quite valuable in such a large-scale project where there are lots of pieces.

Simple Transformation - ABAP 2 XML

Dear all,
Finally I was able to transform an internal table to xml using ST. The question is: Can I create different structured XML-files using the same (structured) internal table. Or is there some kind of a 1:1 relationship (between an ITAB structure + XML structure)?
1) Data declaration
TYPES: BEGIN OF ty_curr,
 tcurr TYPE tcurr_curr,
 gdatu TYPE gdatu_inv,
 ukurs TYPE ukurs_curr.
TYPES: END OF ty_curr.
DATA: gt_tcurr TYPE TABLE OF ty_curr.
2) Data selection
Select * into corresponding fields of table gt_tcurr from tcurr where...
3) Transformation ABAP 2 XML
 CALL TRANSFORMATION z_tcurr
 SOURCE root = gt_tcurr
 RESULT XML g_xml_string.
<?sap.transform simple?>
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates">
<tt:root name="ROOT"/>
<tt:template>
 <tt:serialize>
 <rates>
 <tt:loop name="line" ref=".ROOT">
 <currency>
 <tt:value ref="$line.tcurr"/>
 </currency>
 <date>
 <tt:value ref="$line.gdatu"/>
 </date>
 <rate>
 <tt:value ref="$line.ukurs"/>
 </rate>
 </tt:loop>
 </rates>
 </tt:serialize>
</tt:template>
</tt:transform>
Result (XML)
<?xml version="1.0" encoding="utf-8" ?>
- <rates>
<currency>USD</currency>
<date>01.01.2010</date>
<rate>-1.1868</rate>
<currency>EUR</currency>
<date>01.01.2010</date>
<rate>-1.1791</rate>
<currency>USD</currency>
<date>02.01.2010</date>
<rate>-1.1864</rate>
<currency>EUR</currency>
<date>02.01.2010</date>
<rate>-1.1864</rate>
</rates>:
so far so good... BUT; if I want to get another XML structure
Example 1) -> sorted by currency
<?xml version="1.0" encoding="utf-8" ?>
- <rates>
<currency>USD
<date>01.01.2010</date>
<rate>-1.1868</rate>
<date>02.01.2010</date>
<rate>-1.1868</rate>
</currency>
<currency>EUR
<date>01.01.2010</date>
<rate>-1.1868</rate>
<date>02.01.2010</date>
<rate>-1.1868</rate>
</currency>
</rates>
Example 2) -> sored by date
<?xml version="1.0" encoding="utf-8" ?>
- <rates>
<date>01.01.2010</date>
 <currency>USD</currency>
<rate>-1.1868</rate>
 <currency>EUR</currency>
<rate>-1.1868</rate>
<date>02.01.2010</date>
 <currency>USD</currency>
<rate>-1.1868</rate>
 <currency>EUR</currency>
<rate>-1.1868</rate>
</rates>
How can I achieve output example 1+2 using the same internal table as a source? Is this possible? I guess this can be solved within the transformation, right? Any help appreciated.
Best regards
Benno

Thanks for all answers so far. Changing the sequence is not a "problem". What I want to achieve is to change hierarchy of the xml. I'll try to explain again with a simple example:
ITAB (structure):
name; birthday; ***; first name
ITAB (content):
Smith; 01.01.1970; M; Paul
Smith; 01.01.1970; F; Stefanie
Smith; 01.02.1980; F; Barbara
White; 01.02.1980; M; Steve
I want to pass the itab exactly the way it is (ok, sorting is allowed). Question: Can I achieve the following XML's using ST? I guess/hope this can be solved with variables/groups/condition statements within the transformation coding?
Example xml- 1) Sorted/Grouped by Name/***
<person>
 <name>Smith
 <***>M
 <birthday>01.01.1970</birthday><first name>Paul</first name>
 </***>
 <***>F
 <birthday>01.01.1970</birthday><first name>Stefanie</first name>
 <birthday>01.02.1980</birthday><first name>Barbara</first name>
 </***>
 </name>
 <name>White
 <***>M
 <birthday>01.02.1980</birthday><first name>Steve</first name>
 </***>
 </name>
</person>
Exampe xml-2 ) Sorted/Grouped by Birthday (Names only)
<person>
 <birthday>01.01.1970
 <first name>Paul</first name>
 <first name>Stefanie</first name>
 </birthday>
 <birthday>01.02.1980
 <first name>Barbara</first name>
 <first name>Steve</first name>
 </birthday>
</person>

Need Help With File Matching Records

I need help with my file matching program.
Here is how it suppose to work: FileMatch class should contain methods to read oldmast.txt and trans.txt. When a match occurs (i.e., records with the same account number appear in both the master file and the transaction file), add the dollar amount in the transaction record to the current balance in the master record, and write the "newmast.txt" record. (Assume that purchases are indicated by positive amounts in the transaction file and payments by negative amounts.)
When there is a master record for a particular account, but no corresponding transaction record, merely write the master record to "newmast.txt". When there is a transaction record, but no corresponding master record, print to a log file the message "Unmatched transaction record for account number ..." (fill in the account number from the transaction record). The log file should be a text file named "log.txt".
Here is my following program code:

I am not sure what is wrong with my code above to make my results different from the correct results.
Much help is appreciated. Please help.

From the output, it looks like one problem is just formatting -- apparently you're including a newline in log entries and not using tabs for the newmast output file.
As to why the numbers are off -- just from glancing over it, it appears that the problem is when you add multiple transaction values. Since account.combine() is so simple, I suspect that you're either adding creating transaction objects incorrectly or not creating them when you should be.
Create test input data that isolates a single case of this (e.g., just the Mary Smith case), and then running your program in a debugger or adding debugging code to the add/combine method, so you can see what's happening in detail.
Also I'd recommend reconsidering your design. It's a red flag if a class has a name with "Create" in it. Classes represent bundles of independant state and transformations on that state, not things to do.
