How to compile the Java classes generated in JAXB

I am using Windows 2000 Operating System. I found a xjc
batch file on the sun's java forum.
I used that to generate classes from XML. After generating
the classes I could not compile
the classes each depends on other AND THEY REQUIRE BOTH
CLASS FILES.
I will attach the schema file and dtd . Can you explaine me the problem.

How to pass the java object into the spring controller

Hi Friends
When I hit the url at the first time my call goes to the spring controller and sets the userDetails objects in the modelAndView.addObject("userDetails", userDetails.getUserDetails()) and returns the userDetails.html page. if I click any link in the same page i want to pass same (userDetails) object thru javascript or jquery and calls the another(controller) method and returns the same (userDetails.html) page.
It means how can i pass the java object thru javascript or jquery and calls the controller. if i get the same object in my controller i can avoid calling the db again. please help me out to resolve this issue. i am tired of fixing this issue.
Regards
Sherin Pooja

If you want to avoid calling the database again then cache the data.
However before you do that make sure that calling the database, in the context of YOUR system, is going to be an actual problem.
For example there is absolutely no point in caching a User object when only one user an hour is actually using the system.

Hi,
You don't have to worry about compliation. XI will automatically comple it when you create the udf, activate it and test your mapping. In case of any error it will give compliation error there itself.
Regarding all the mandatory jar files which are required for compilation is already available in XI server.
If you are using any third party libraries(jar files) you just need to add the jar file in your external definition and need to import the necessary packages in User Define Function. I hope it answers all your questions.

How to make the java files compile for a project created outside of Eclipse

Hi^^,
I have created a project outside of Eclipse. It has the following folders
1. config
2. source
3. WEB-INF
I want to execute the project on remote server. Will it compile automatically creating a new folder for .class files corresponding to the source folder or do i need to include a build.xml to enable the project to create a new folder for .class files. Also pls tell me how do I write this build.xml
Please advise.

Hi^^,
Actually I have created a project without using eclipse.
My source files are inside WEB-INF/source
Now I want to compile the files using build.xml so that I can create class files. I am using the following build.xml
<project name="jsp" default="all" basedir="./">
<property environment="env"/>
<property file="ArmorJSP.properties"/>

<property name="source" value="."/>
<target name="all" depends="copy, jspc, testservlet"/>

<target name="jspc">
    
    <java classname="weblogic.jspc" fork="yes">
      <arg line="-webapp ${APPLICATION_HOME} -compileAll -d ${APPLICATION_WEB_CLASSES} ${source}/*.jsp"/>
      <classpath>
        <pathelement path="${WL_HOME}/lib/weblogic_sp.jar;${WL_HOME}/lib/weblogic.jar;${ARMOR_HOME}/ARMORSecurity.jar;${ARMOR_HOME}/ARMORUtil.jar"/>
      </classpath>
    </java>
</target>

<target name="testservlet">
    
    <javac destdir="${APPLICATION_WEB_CLASSES}" srcdir="${source}" includes="*.java">
      <classpath>
        <pathelement path="${WL_HOME}/lib/weblogic_sp.jar;${WL_HOME}/lib/weblogic.jar;${ARMOR_HOME}/ARMORSecurity.jar;${ARMOR_HOME}/ARMORUtil.jar"/>
      </classpath>
    </javac>
</target>
<target name="copy">
    <copy todir="${APPLICATION_HOME}">
      <fileset dir="${source}">
        <include name="*.jsp"/>
      </fileset>
    </copy>
</target>
</project>I do not know how to compile the project using this build.xml
The motive of doing all this is to understand how is Eclipse doing the build project step. I simply cannot find any build.xml inside any of my projects created in Eclipse however when right click on the project and choose build project, it compiles excellently. ???

Hi Experts,

how to get the background java code of the message mapping(graphical mapping).
And where to view it?

Hi sowmya,
Open any Message mapping in IR. Press <b>CtrlShift0(zero)</b> to open a new menu.
There you will find an option "Is Java Source Code Available?"
There will be an export button nearby. Use it to get the code.
Open it in a zip , you will see the hide java code.

How to retrieve the java object in a proxy service in osb -- Plz help

Hi all,
I have a singleton java class which runs whenever the weblogic server gets started and store the output in its object. I need to access this java object from a proxy service in osb.
We tried using java call out and retrieved that object but we couldn't know how to parse that object into XML.
We are not sure of using the java call out in osb to solve this purpose because whenever we use a java callout, that particular java code will run which is not the case of singleton class.
So kindly help us how to retrieve the java object which holds the output without running the java code every time because its already run and holding the output in its object.
Regards
Prabhu

here the doc http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/userguide/context.html#wp1106656
but I guess you are already at the stage of getting a POJO in a first Java Callout and passing the POJO to a second Java Callout, which should then return it to OSB as a XMLObject.
My recommendation is to write a Java function which returns a XMLObject and uses a XMLCursor to populate it with the values of the POJO.
An XMLObject returned to the OSB is automatically transformed in a "XML" variable (which in reality is represented as a XMLObject in the Pipeline context)
Here some code sample:

How to use the Java embedding activity in BPel

hi all,
How to use the java embedding activity in BPEL
pls can u provide sample example

1 Use [Oracle BPEL Process Manager Client Java API Reference|http://download-uk.oracle.com/docs/cd/B31017_01/integrate.1013/b28986/overview-summary.html] and especially [com.collaxa.cube.engine.ext|http://download-uk.oracle.com/docs/cd/B31017_01/integrate.1013/b28986/com/collaxa/cube/engine/ext/BaseBPELXExecLet.html]
Instead of System.Out.println use addAuditTrailEntry(java.lang.String message)
2. If you want to import a package write in code (Source View) of bpel process
+<bpelx:exec import="package_name"/>+ for example +<bpelx:exec import="java.util.regex.Matcher"/>+
example 1:
String bodyAsString;
StringBuffer myStringBuffer = new StringBuffer();
try {
bodyAsString = (String)getVariableData("BodyString");
addAuditTrailEntry("bodyAsString1: "+ bodyAsString);
Pattern pattern = Pattern.compile("goodDay");
Matcher matcher= pattern.matcher(bodyAsString);
while (matcher.find()) {
matcher.appendReplacement(myStringBuffer, "shitDay");
matcher.appendTail(myStringBuffer);
bodyAsString = myStringBuffer.toString();
addAuditTrailEntry("bodyAsString2: "+ bodyAsString);
} catch (Exception ex) {
addAuditTrailEntry("Failed+bodyAsString",ex.getMessage());
I put in code (Source View) the following
<bpelx:exec import="java.util.regex.Matcher"/>
<bpelx:exec import="java.util.regex.Pattern"/>
example2:
Object temp;
try {
temp = ((XMLElement)getVariableData("inputVariable","payload","/ns2:FiscalisMessage/ns2:Body")).getChildNodes().item(1);
setVariableData("AdjReceipt",temp);
addAuditTrailEntry("ok",temp.toString());
catch (Exception ex) {
addAuditTrailEntry("Failed :",ex);
I put in code (Source View) the following
<bpelx:exec import="oracle.xml.parser.v2.XMLElement"/>

You need to populate that field using cmod code. Find out from which table that field is and go to transaction cmod then enter project name and select component radio button then display.
Now select the FM EXIT_SAPLRSAP_001 if your datasource is transactional dataource
EXIT_SAPLRSAP_002 for master data attibute
EXIT_SAPLRSAP_003 for Hierarchies
EXIT_SAPLRSAP_004 for text
then populate code .
After your code then delete data from ods then reinit to populate the enhanced field.
Hope it helps..
