Query in Unmarshaling using JAXB

Hi,
I have some chinese characters in my xml. When i try to read those string from XML using JAXB Unmarshaling and print the same, it is getting changed to some unicode character.
Help me in this regard.
As the chinese characaters are getting changed after preview, if u can contact my thro mail, it will be better ([email protected] is my email id)
Regards
Ravishankar

Please post the error message and the exception stack.
My guess is that the error is: your VO's SQL statement did not include the primary key attribute (say Empno).
Thanks.

Using JAXB with Oracle CEP

Just a tip to anyone looking to use JAXB or other APIs requiring class loading with CEP. Because CEP uses OSGi, you must provide your own class loader to use (in this example) JAXB 2.0. For example:
cLoader = com.mycorp.cep.message.schema.ObjectFactory.class.getClassLoader();+
jaxbCtxt = JAXBContext.newInstance("com.mycorp.cep.message.schema", cLoader);+
UnMarsh = jaxbCtxt.createUnmarshaller();+
The code snippet above demonstrates that before obtaining a JAXBContext object, there must be a separate class loader defined that is not the thread's default class loader. I used the JAXB ObjectFactory class that is generated when processing the schema XSD file.
There's probably other ways to do this, but I found this way to be the easiest solution so far that works.

I just downloaded JAXB 2.1 EA 2 from java.net
The xjc tool supports these arguments:
-relaxng : treat input as RELAX NG (experimental,unsupported)
-relaxng-compact : treat input as RELAX NG compact syntax (experimental,unsupported)I haven't tested this out yet. Let me know if you try this solution.

Serialazation of objects created using jaxb

I am using jaxb to create java classes from a dtd. Problem is that I am not able to serialize these objects. We are using JMS queues and want to compare the cost (performance) of marshal/unmarshal and serialize/deserialize of these objects. Jaxb faq provides a example http://java.sun.com/xml/jaxb/CheckbookBalance.java but it uses marshal and unmarshal methods to do serialization. I have tried changing the classes generated by jaxb to implement serializable but i get runtime "Object couldnot be serialized" exception. Is there any way to make the objects of classes generated by jaxb serializable?
Thanks,
-Rakesh

IMHO these classes are not meant to be serialised, the XML produced is the medium that is tranmitted between programs. The XMLB classes are available at both ends to do the marshalling/unmarshalling.I dissagree, xml is just an interface to the outside world, so to speak. I'm working with a project that uses jini and rmi, I really don't need the extra hasle of writting custom serialization classes.

Entity include with relative path in XML using JAXB

Moving this from the Java Technologies for Web Services forum to this one.
With the jwsdp jars I'm trying to use JAXB to load in several specified XML files. This works fine. The XML files are read in from a relative link "/templates/mainXML.xml" and the xml string read in and passed to the unmarshaller as a StreamSource:
BufferedReader reader = new BufferedReader(new InputStreamReader(getClass().getResource(xmlPath_).openStream()));
while ( (line = reader.readLine()) != null) {
buff.append(line.trim()+"\n");
String xml = buff.toString();
u.unmarshall(new StreamSource(new StringReader(xml)))
But my XML files are becoming rather large with some repitition across the files so I'd like to use the entity incude in the header of the XML to abstract some of the XML into addMe.xml e.g:
<!DOCTYPE StrategyTemplate [
<!ENTITY IncludeTimeComponent SYSTEM "file:///templates/addMe.xml">]>
with &IncludeTimeComponent;
But it gives this error:

It works fine if I put the file in the working directory or supply the full path e.g.
<!DOCTYPE StrategyTemplate [
<!ENTITY IncludeTimeComponent SYSTEM "file:///C:/dev/templates/addMe.xml">]>
with &IncludeTimeComponent;
I've tried using jwsdp2.0 jars rather than 1.4 I was using previously, but with the same result.
But I don't want to do that, because I don't know where that might be. I'd like to be able to supply the xml file's path as it would be shown within a JAR as I do currently for the mainXML.xml files. Thanks in advance for any help!

Oh, I see why. When XML talks about a "relative path" that means relative to the URL the XML was loaded from. But when the parser doesn't have such a URL -- for example in cases like yours where you are parsing from a String -- then it falls back to assuming the XML was loaded from the current working directory.
This is almost never a good assumption, but what else can it do?
Looking at your code, I don't understand why you are parsing from a String anyway. All of that code that reads from an input stream, ignoring the line endings and putting back new line endings, seems pointless to me. You should just marshal directly from getClass().getResource(xmlPath_) as far as I can see. Then your relative paths would work just fine.

Use jaxb api

Hello,
I would like to use the JAXB api to parse XML document.
The aim is to parse SOAP message sent by a server.
- I've download jaxb-api.jar, jaxb-impl.jar, jaxb-lib.jar and jaxb-xjc.jar.
- Here my code :
JAXBContext jc = JAXBContext.newInstance( "aaa.bbb.ccc");
Unmarshaller u = jc.createUnmarshaller();
Object o = u.unmarshal( httpConn.getInputStream() );
==> Here generated error :
JAXBException : Unable to locate jaxb.properties for package aaa.bbb.ccc
I use the IDE Eclipse, must I do a particular configuration ?
Could you help me please ?
Thanks.
Delphine.

Delphine,
As far as I understand other than adding the 4 java archives you mentioned to the class path, there's nothing else as far as set up/configuration is concerned.
As the exception clearly says, its a pure JAXB exception and not from the SAP server. Are you using jaxb-1.0-beta , if yes, it has this bug.
There are some solutions mentioned in
PO number ranges
and
Hope this helps,

What my program do is to get the encoding of XML files and convert them to UTF-8 encoding files, while I need this "encoding" information of the original XML document thus I can convert...
After reading specifications and JDOM docs, the truth turns to be disappointed, no function is provided to get this information in JDOM level 2(the current released one), while it's promissed that this function will be provided in JDOM level API....
Thanx all for your help and attention!!!

How to pass multiple query string values using the same parameter in Query String (URL) Filter Web Part

Hi,
I want to pass multiple query string values using the same parameter in Query String (URL) Filter Web Part like mentioned below:
http://server/pages/Default.aspx?Title=Arup&Title=Ratan
But it always return those items whose "Title" value is "Arup". It is not returned any items whose "Title" is "Ratan".
I have followed the
http://office.microsoft.com/en-us/sharepointserver/HA102509991033.aspx#1
Please suggest me.
Thanks | Arup
THanks! Arup R(MCTS)
SucCeSS DoEs NOT MatTer.

Hi DH, sorry for not being clear.
It works when I create the connection from that web part that you want to be connected with the Query String Filter Web part. So let's say you created a web part page. Then you could connect a parameterized Excel Workbook to an Excel Web Access Web Part
(or a Performance Point Dashboard etc.) and you insert it into your page and add
a Query String Filter Web Part . Then you can connect them by editing the Query String Filter Web Part but also by editing the Excel Web Access Web Part. And only when I created from the latter it worked
with multiple values for one parameter. If you have any more questions let me know. See you, Ingo

Can we use Result from another query in Webi using Bex uery universe?

Hi,
Can we use Result from another query filter option in Webi to create a report using a Bex Query universe?
I need to create a report using two universes, one is Bex Query Universe and the other is Orcle universe. I have two queries, one is using Oracle universe; the other using Bex Query universe. I need to pass the Oracle data from the Oracle query to the Bex Query query to get the matched data from SAP Bex query.
I used Result from another query in the query filter panel for the query using Bex query universe. But I got an error saying that 'A filter contains a wrong value. you cannot run this query. (Error: WIS 00007). The data used in the filter on both sides are the same. they are char.
I have tested by using two queries from the same Bex query universe to see if the Result from another query filter option works. And I got the same error.
Has anyone run into the same issue and if this is possible and what should be the solution?
Thanks in advance!
Edited by: BO_Haiyan on Oct 6, 2010 3:47 PM

In that situation:
Create two queries : Oracle and BW query.
@ Report:
As you have to see result set from both the Dataproviders, correct? To achieve thise one must have common dimension objects to merge them at report and use Objects those are coming from both queries to use them in single Table/Report.
Unless you don't use Merge Dimensions, you don't get a chane to use both queries objects in single Table/Report. (It will give tooltip saying: You can't drop here -- Incompatable Objects)
In case, if you don't have common dimensions, change object definitions to Detail objects, for those required.
Hope it helps you.
Thank You!!

Java Mapping Using JAXB [Java Arch for XML Binding]

Hi All,
Anyone tried using JAXB [Java Architecture for XML Binding API available with Java WebServices Pack] technique for XML processing in Java Mapping??
I am facing the following problems..
1. I am not able to generate namespace while marshalling target XML [In standalone mode and not tried in XI].
2. What are the jar files we need to import?
I tried importing the following jar files in XI.
jaxb-api.jar,jaxb-impl.jar,jaxb-libs.jar,jax-qname.jar,namespace.jar,relaxngDatatype.jar
and getting some errors while importing these files in XI.
3. It throws error at runtime [Interface Mapping-Test Tab]
like Resource not found:javax/xml/bind/Messages_en.properties,javax/xml/bind/Messages_en_US.properties
4. Even after creating a copy of available file Messages.Properties with name: Messages_en.properties and Messages_en_US.properties.. it is not generating any messages in Target message tab
Thanks in Advance,
Ananth Chinnaraj

Sravya ,
I have searched wide and far for this, but no success.
A lot on JAXB XI and Webdynpro, but nothing on JAXB, XI and mappings.
Could you please post the url here ?
Thanks and kind regards,

How to use JAXB generated classes with SOAP

hello,
I have a library of JAXB generated classes for my web service. There is a Java class for each web method defined in my schema. For example, my getLocation method is mapped to GetLocation.class.
However my web service is SOAP based, so I am having to manually strip off the SOAP elements to be able to unmarshall the getLocation xml to a GetLocation class.
I am noticing a disconnect between JAXB and other Java SOAP and RPC libraries. Does anyone know how to create a JAXB class for SOAP Envelopes and Bodys? Does anyone have any ideas how to incorporate the existing Java web service libraries with JAXB?
Thanks in advance.

Please help, if you have come across this or similar issue..
Or let me know how you create a .xjs file.
Any idea what is the main file class in jaxb-rt-1.0-ea.jar that creates a xjs file ?
All/any help appreciated. Thanks in advance.

Hi,
You cannot use xjs files with the JAXB Beta RI.
This has been mentioned at http://java.sun.com/xml/jaxb
"Note that this version is not API-level compatible with the previous released version of the specification and DTD schemas are no longer supported."
You can generate code using the xjc binding compiler for schema documents.
Pls let me know if you have more questions

Issue While executing the Query for Pagination using ROWNUM with like

Issue While executing the Query for Pagination using ROWNUM with like.
Database is Oracle11G.
Oracle Database Table contains 8-9 lakh records
1) SQL equal (=)
SELECT /*+ FIRST_ROWS(n) */ ROWNUM RNUM, A.* FROM LINE A
WHERE A.REFERENCE = 'KMF22600920'
Execution Time:- 0.00869245 seconds
Returns 2 resultsets
2) SQL like (one %)
SELECT /*+ FIRST_ROWS(n) */ ROWNUM RNUM, A.* FROM LINE A
WHERE A.REFERENCE = 'KMF22600920%'
Execution Time:- 0.01094301 seconds
Returns 2 resultsets
3) SQL like (two%)
SELECT /*+ FIRST_ROWS(n) */ ROWNUM RNUM, A.* FROM LINE A
WHERE A.REFERENCE like '%KMF22600920%'
Execution Time:- 6.43989658 seconds
Returns 2 resultsets
In Pagination, we are using Modified version of SQL Query 3) with ROWNUM as mentioned below :-
4) SELECT * FROM (
SELECT /*+ FIRST_ROWS(n) */ ROWNUM RNUM, A.* FROM LINE A
WHERE REFERENCE like '%KMF22600920%' AND ROWNUM <= 20 ) WHERE RNUM > 0
Execution Time:- Infinite
ResultSets:- No as execution time is infinite
a) Instead of like if we use = in the above query it is returning the 2 resultsets (execution time 0.02699282 seconds)
b) Instead of two % in the above query, if use one example REFERENCE like 'KMF22600920%' it is returning the 2 resultsets (execution time 0.03313019 seconds)
Issue:- When using two % in like in the above query i.e. REFERENCE like '%KMF22600920%' AND ROWNUM <= 20 ) , it is going to infinite.
Could you please let us know what is the issue with two % used in like and rownum
5) Modified version of Option1 query (move out the RNUM condition AND RNUM <= 20)
SELECT * FROM (
SELECT /*+ FIRST_ROWS(n) */ ROWNUM RNUM, A.* FROM LINE A
WHERE REFERENCE like '%KMF22600920%' ) WHERE RNUM > 0 AND RNUM <= 20
Execution Time:- 7.41368914 seconds
Returns 2 resultsets
Is the above query is best optimized query which should be used for the Pagination or still can improve on this ?

This would be easier to diagnose if there was an explain plan posted for the 'good' and 'bad' queries. Generally speaking using '%' on both sides precludes the use of any indexes.

In Query of Query, can't use LEFT() function?

Hi All,
I've got an LDAP query that I use for our employee directory. I then do a Query of Queries and do LEFT(SN,1) to separate out by first character of last name [A,B,C,D,E...] etc.
I had this working just fine in Railo CFM, but now I'm using Adobe CF and can't get that to work. I'm on CF9 Standard.
I've read the Query of Queries guide, but didn't find anything helpful there. Even when I do
'#LEFT(SN,1)#' as FirstCharacterOfLastName in my query, what I get is the value for the last row, not the value of each row as it's looping through the recordset.
Am I missing something? Any way to get that to work? Is that addressed in CF10?
thx.Ben

You need to understand two things:
1) any CFML in your SQL string within a <cfquery> tag pair is processed by CF before the SQL string is passed to the DB driver. So your #left()# expression won't be processed "per row", because it's processed before the DB engine does any "per row" operations.
2) QoQ's SQL support is tragically minimalist. This lists all the functions it supports:
http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WSc3ff6d0ea77859461172e0811cbec0e4fd -7ff0.html#WSc3ff6d0ea77859461172e0811cbec0e4fd-7fcc
With the addition of two string functions: UPPER() and LOWER(). Oh, and CAST() (if that can be seen as a function).
That's it. That page in the docs describes all the functionality QoQ has. There's nothing missing 9as far as I know). That's it. There's not much to it.
I've been lobbying Adobe for a number of years to pull finger and improve QoQ to the point that it's more than just a curio, but they don't seem interested.
As to why your code works on Railo? Railo does some weird things, and doesn't stick to the precedent Adobe dictates their language should follow. Depending on who you talk to, this is either a feature or a barrier to entry (I'm mostly ambivalent, but err towards the latter camp). But perhaps Railo's QoQ processor supports LEFT().
Basically... you're gonna have to approach this differently: loop over the query with <cfloop> (etc) and update it row by row. This is pretty much what QoQ is doing anyhow, so I don't think you'll see a performance degradation. Well: you won't... because you can't do what you want to do with QoQ at all, I guess ;-)
