Validating PCDATA in Java
In my application, users enter a name in a JTextField and this name becomes the value for a servlet-name in web.xml.
I want to validate the input to make sure it is a valid servlet-name or valid PCDATA
Is it sufficient to check for the characters <, >, & and escape them or is there more validation to do?
It seems that the servlet-name value is an xsd token, so it seems I need to do more validation and conversion.
If I need to do so much validation, is there any tool or would I have to load an XML parser against the input?
Thanks
John

Groovy is really meant to support a looser syntax than Java (it's really Ruby-like in its syntax, and has a whole bunch of scripting extensions). The other two (BeanShell, especially) stick to Java syntax, pretty much (though each has some interesting "scripting extensions").

we have adddetails.jspx page with 5 fields and a commit button in which aid is the primary key field.And we did validations in EOImpl.java file for all the fields.
when any one of the field validation fails and then if we goto home page and come back to adddetails.jspx page and then even if we enter values correctly it is showing error saying aid already exists.
we even tried VO.clearcache(entityname,true) in backing bean.
Here the point is when any one of the field validation fails and if we enter values correctly with out going to home page and coming back to adddetails.jspx it is working fine.Muralidaran,
What's wrong with default validation? I.e. validation available via set of constraints for your own SimpleType in LocalDictionary?
If it's not sufficient you may try something like this: /people/valery.silaev/blog/2005/11/29/800format-your-way (here I were talking about formatting, but validation was used as well, implicitly

How to do fronwend validations with out JAVA code
Hi Frndz...
In my application i did the fron end validatios as per requirment in java , as per requirement my application requires too much validations i did entirely in java .
But itz takling much time , in java will go for javascript for validations is there any thing is aivla in webdyn pro for vaildations
my code
if(division1 !=null && division1 !="")
blnValueDivision = true; }
else
msgMgr.reportContextAttributeMessage(wdContext.nodeInitTableV().getInitTableVElementAt(i),attrInfoDivision,IMessageNoBusinessSheetComp.ERROR__MESSAGE__MANDATORY,new Object[]{"Division"},true);
blnValueDivision = false;
if(location1 !=null && location1 !="")
blnValueLocation = true;
else
blnValueLocation = false;Hi,
webdynpro doesnt support java script handling . This is taken care by the framework. Only option is to reduce the roundtrip and try to validate every thing in a submit button.

Complex "validation rule" using Java Bean code
Hi,
I have never used validation rules with jdeveloper, but i need a complex validation rule of one column of my table.
Can i put a "validation rule" on an attibute of a view object, or on a column of a table, that use Bean code ?
My column must contain different values depending of the other columns of the table, so i think i can't do this without java code...
I tried to doubleClick on the column to create a validator, but I have put a "Print" inside, and seen that it is executes lots of times, but I want to execute the validation only when the value of the column change !
How can I do this ? What do i need to use ?
Regards,
TriggerI have use John's solution, it works well !
Sorry vinod_t_krishnan i am good with java but i don't know how to use well EL Expressions so I did not try your method...
The code if so is interested...

Screen validations in webdynpro java (NWDS 7.0)
Hi Experts,
We are using Portal 7.0 version and NWDS 7.0, we have developed one wdj application .in this application i have designed one dropdown key with "YES" or "NO" options.
if user click on YES ,then i should be ask the Enter the amount and after enter the amount i will go to another dropdown key field(department list field) with yes or no values, same thing procedure repeat for this dropdown field(department list field)also.
If user click on "NO", it should be go for direct next dropdown field(department list field)..
Please help on this issue.
Regards,
Vanithahi vanitha<
here is the code
create one attribute of type Visibility and bind it to the department dropdown and set the visibility using the below code

Should customised row validation rules put in EntityImpl.java or EntityDefImpl.java?
Qestion:
1) Should customised row validation rules put in EntityImpl.java or EntityDefImpl.java?
2) Where am I recommended to define customized Exceptions?
Thanks for any replies!Qestion:
1) Should customised row validation rules put in EntityImpl.java or EntityDefImpl.java?If you want to write validation logic in java, EntityImpl subclass is the place to do it. You may choose to write validation per attribute in the relevant setXXX methods (where XXX is attribute name)
or in the validateEntity() method (before/after calling super.validateEntity() as your case may be).
2) Where am I recommended to define customized Exceptions?You should define new exceptions in a package separate from your server classes, (so that you can download them to client-side incase you are in a thin-client environment).
Exceptions should be a sub-class of JboException if you want these exceptions to be tier-independent and work without conversions in Bc4J.
If the exceptions are part of validation logic you may choose to subclass ValidationException or one of the subclasses thereof.
Thanks for any replies! -
Question about Validation Timing in SAXParser.
Hi,
I'm using the SAXParser (9.0.4) in validating mode against a DTD. When I tried to catch validation errors
using the ErrorHandler interface, I saw the ErrorHandler methods are called back at the end of the parse process (after the enddocument event).
Is there anyway to change this behaviour. I need to know the erronious cases during the parse not once it is finished.
When I plugged Xerces in place of Oracle's parser it behaved as expected.
Thanks in advance
EmreHi Deepak,
Here is the case I have written using your sample.
As you will see from the output, the error callback
is not called in sync with the error position.
Other parsers I have tried report the expected
output. Is there a mistake I have done?
Thanks for your efforts.
Regards.
Emre

Java Stored Procedure in EXECUTE IMMEDIATE
Hi,
I need advice for the following.
I'm on Oracle 11g R2. I'm testing application in Oracle 11gR1 and R2 and Oracle Express.
Purpose is to generate XML reports.
I have PLSQL Stored Procedure which does that, but since there is bug in Oracle11gR2 related to XMLTRANSFORM I have and Java Stored Procedure which is workaround. They are both compiled, valid etc.
Java class is :
import java.io.PrintWriter;
import java.io.Writer;
import oracle.xml.parser.v2.DOMParser;
import oracle.xml.parser.v2.XMLDocument;
import oracle.xml.parser.v2.XSLProcessor;
import oracle.xml.parser.v2.XSLStylesheet;
* This class is used as Java stored procedure
* There is a bug on Oracle11gR2, related to the limitation on the number of style sheet instructions
* This stored procedure is workaround when PLSQL code can not be used.
* File must not have package, otherwise is wrongly compiled in DB
public class JavaXslt {
public static void XMLTtransform(oracle.sql.CLOB xmlInput,oracle.sql.CLOB xslInput,oracle.sql.CLOB output) throws Exception{
DOMParser parser;
XMLDocument xml;
XMLDocument xsldoc;
try{
parser = new DOMParser();
parser.parse(xmlInput.getCharacterStream());
xml = parser.getDocument();
parser.parse(xslInput.getCharacterStream());
xsldoc = parser.getDocument();
XSLProcessor processor = new XSLProcessor();
XSLStylesheet xsl = processor.newXSLStylesheet(xsldoc);
Writer w = output.setCharacterStream(1L);
PrintWriter pw = new PrintWriter(w);
processor.processXSL(xsl, xml, pw);
}catch (Exception ex){
throw ex;
PROCEDURE Java_XmlTransform (xml CLOB, xslt CLOB, output CLOB) AS LANGUAGE JAVA
NAME 'JavaXslt.XMLTtransform(oracle.sql.CLOB, oracle.sql.CLOB, oracle.sql.CLOB)';
I'm calling Java stored procedure from PLSQL Stored procedure (if it is Oracle11gR2) like that :
Java_Proc.Java_XmlTransform(inputXML, xslt, res);
So till here everything works ok. XSLT as applied and output XML (res) is OK.
But when Oracle Express is used Java is out of the question, so there is no Java stored procedure. Howewer PLSQL Stored procedure is still needed.
So I had to put call to Java Stored procedure in EXECUTE IMMEDIATE statement in order to compile to PLSQL package.
But when I do that :
EXECUTE IMMEDIATE 'BEGIN Java_Proc.Java_XmlTransform (:1, :2, :3); END;' USING inputXML, xslt, res;
result value CLOB (res) has zero length...
What am I missing? Should i set return value to Java class?
Hope my explanations are clear though.
ThanksHi odie_63,
Thanks for quick response.
I didn't clearly explained.
When using Oracle 11gR1 and Oracle Express I'm using only PLSQL Procedure.
When using Oracle 11gR2 i have to use Java Stored procedure because there is documented bug in R2.
That's why i have to use EXECUTE IMMEDIATE. I don't know which version is the client DB and whether there is or no Java procedures.
I did tried
EXECUTE IMMEDIATE 'BEGIN Java_Proc.Java_XmlTransform (:1, :2, :3); END;' USING IN inputXML, IN xslt, OUT res; and the result was ORA-06537: OUT bind variable bound to an IN position
When using IN OUT for last parameter i.e.
EXECUTE IMMEDIATE 'BEGIN Java_Proc.Java_XmlTransform (:1, :2, :3); END;' USING IN inputXML, IN xslt, IN OUT res;
there is no exception, but still DBMS_LOB.getlength(res) = 0

# Adaptor adaptor - Component Sink LocalSinkThis is my understanding from reading a few other boards. OpenOffice 3.2 apparently tests for the validity of the Java Runtime Environment by checking some character strings returned by some system functions. The latest version of the JRE from Apple (apparently this was associated with Snow Leopard) did not match the character strings expected by OpenOffice 3.2 and was then therefore rejected as being "corrupted". The release candidate versions of Open Office 3.3 have apparently had this problem corrected, although I have no idea whether it is by adding character strings to the test or eliminating the test entirely. In OpenOffice 3.2, you can turn off use of the JRE, but this may invalidate some third-party plugins.
I strongly suspect that this may be related to the fact that Apple has said that they want to have Oracle provide the JRE updates so that the updates in operating systems and Oracle products are in sync. This may also mesh with some other comments about the relationship between open source JRE development and Oracle. (This is the vastly misquoted messages about Java being deprecated.)
The following is my understanding of the options.
Load an earlier version of the JRE and get OpenOffice to use it. I'm not sure if this can be done.
Use NeoOffice, which apparently made the required change to the tests for JRE's.
Download a release candidate version of OpenOffice 3.3.
Modify the code yourself and compile your own version. (I would not recommend that choice.) -

BI setup: WebAS ABAP Setting - Java to ABAP communication problem
Hello,
i've got a problem during intallation of BI in Netweaver 2004s. The Diagnostics & Support Desktop Tool reports errors in WebAS ABAP Settings. These errors are:
- "Web Template Validation failed due Java to ABAP communication problem (return code:ERSBOLAP018)" with the suggested solution "Check Connector Connection of System Object in Portal System Landscape". What does it mean?
- "Call ABAP->Java for function RSWR_RFC_SERVICE_TEST failed for destination <destination>" and "Call ABAP->Java for function RSRD_MAP_TO_PORTAL_USERS failed for destination <destination>" with suggested solution "Check the data of the destination in transaction SM59. Check that the target host is running and has registered a program id in the gateway." Run of transaction SM59 returns no errors.
Further i've take a look in the log 'dev_jrfc.trc' and there i found the errors:
- Exception thrown by application running in JCo Server
java.lang.RuntimeException: Bean RSRD_MAP_TO_PORTAL_USERS not found on host <host>
- Exception thrown by application running in JCo Server
java.lang.RuntimeException: Bean RSWR_RFC_SERVICE_TEST not found on host <host>
- Exception thrown by application running in JCo Server
java.lang.RuntimeException: Bean RSWR_PREEXECUTION_PROXY not found on host <host>
Can these errors be the cause of the WebAS ABAP Setting error displayed in the Diagnostics & Support Desktop Tool? How they can be solved?
Thanks for your help,
MartinHello Chetan,
thanks for your response. Maybe i've described my problem not clear enough. There is no problem of installation and usage of support & dektop tool, but of installation of BI. The support & dektop tool indicates the errors described above with no other hints. My questions is, if anybody knows, what is the cause of the errors and what i must do, to install BI correctly.
Cheers,

Hello All,
Here my requirement is to validate(check for mandatory fields and length limitation) the incoming message before message mapping.
In PI 7.1, we can do validation of the incoming message at Sender Agreement and Receiver Agreement level by selecting options Validation at IE and Validation at AE.
In case of Outbound scenario's(from SAP ECC to SAP PI) we does not create Sender Agreement.
So, can some one to suggest me how can I validate my incoming message incase of OB?
Thanks,
Regards,
Moorthy>> In case of Outbound scenario's(from SAP ECC to SAP PI) we does not create Sender Agreement. So, can some one to suggest me how can I validate my incoming message incase of OB?
In this case, You cannot use PI's XML Validation. Use Java Mapping. Basically you have to read the XML document using parser to validate and if error stop right there.

Custom Validation in ESS Edit Screen
All,
We have a requirement in ESS Address screens that all country users should key in only English Data. We are in SAP ESS SP12 and all the Address Components are in WD Java. The validation on all the address screen fields for this requiement has to be handled and give an error message back to the user.
The Options that I Checked out were:
1) Handling the Validation through BADI HRPAD00INFTYUI or HRPAD00INFTYBL.
2) Handling the validation in WD Java layer inside the country spoecific components isConsistent method of the Detail View Component controller
Which is the best place (ABAP or JAVA) to handle Custom validations on the Edit Screen and give back message to the user? Please suggest if any other better options are available other than the above mentioned ones.
Regards,
Nagarajan.Hi,
Both are doable if you are good in java and have NWDI ,handling validations in the wd java layer is easy. If you are good in ABAP you can handle in ABAP.It depends on how you write your code, if you do validations in java and if your validation fails you can show errors to user right away which will reduce your call to backend at isconsitent method for checking the errors.
Thanks,

thanks for your contribution. But how I already said we have seen that the first error message:
The error is: javax.servlet.UnavailableException: Cannot load a validator resource from '/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml'
But behind that message is an additional message that describes the real root cause of the problem:
SEVERE: Cannot find resource "org/apache/commons/digester/xmlrules/digester-rules.dtd"
org.apache.commons.digester.xmlrules.XmlLoadException: Cannot find resource
"org/apache/commons/digester/xmlrules/digester-rules.dtd"
Unfortunately we have no idea why the dtd file can not be loaded. The appropriate line of code is:
getClass().getResourceAsStream("<link_to_resource")
And this returns a NULL object. The NULL object causes the general exception and finishes the instantiation of Struts.
Any additonal hints?

Hierarchical Filter Web Item causes validation warning.
When I validate my web template which contains a hierarchical filter web item agianst the server I get the following warning (W1):
Mapping for Service item_validation_service for Object HIERARCHICAL_FILTER_ITEM missing
Maybe this also relates to my problem of not having the possibility to choose a characteristic for the hierarchical filter (see my post <a href="https://forums.sdn.sap.com/thread.jspa?threadID=209968&tstart=0">https://forums.sdn.sap.com/thread.jspa?threadID=209968&tstart=0</a>)
How can I fix this mapping issue?
Thanks to any answers in advance.
Best regards,
PhilippHello,
Your first problem is that ABAP SP does not equal Java SP. This is not a valid scenario.
Please update both to <b>the same SP level</b>.
After it, please retest your problem. I think that the problems will be solved (at least this one with validation service).
Short explanation to validation service:
Every template created in WAD will be validated before saving it. We have two validations:
1. one is locally with the meta data this checks if:
- all used parameters are on its place,
- all parameter values are valid,
- all defined items are existing...
2. second one is extended validation on the Java Server: this one checks i.e. following:
- are all used data providers valid
- are all used characteristics valid
- item dependent validation (e.g. if one item needs a dependency between to setting - this can be checked here)
The first one will be executed in Front-End and in ABAP Back-End. The second one in Java. Because your Java stack is /probably/ lower than ABAP, this validation does not work.
I hope I have explained it clearly.
