Parameter with Long String

I am opening a new JSP from current JSP. The new JSP needs a parameter, which happens to be very large > 3800 chars. I am using javascript function window.open(url) where url has everything including above large string. When I print the string I received in new JSP I get only 1880. Example
url=/xyz/x1.jsp?x1_param=001001001001....( 3800 chars )
Is there any size limitation with the parameter passed through JSP?
If yes, then how do I work arround this size limitation problem?

There is a limit to the length of parameters that you can pass in a url. I forget what the exact number is but apparently it is less than 3800.
You could try opening a blank window and then have the JavaScript automatically submit a post on a hidden form where teh response is targetted to the new window.

[Forum FAQ]How do I add a search feature in the parameter with long drop down list?

Introduction
There is a scenario that thousands of values in the drop-down of a parameter. Scrolling through the large drop down list is slow and cumbersome. Is there a way that we add a search feature in the report, so that it can filter down the values in the drop
down list to a smaller list of values?
Solution
To achieve this requirement, we can add a parameter with multiple keywords ahead, then all of available values which are begin with the keyword will display in the parameter list. In this scenario, we can create cascading parameters. One is a keyword parameter,
and the other parameter is based on the keyword to display the available values.
In order to enable the user to type multiple keywords, we can use the query below to create a split function which takes the list and the de-limiter as input parameters and splits all the values in the database:
CREATE FUNCTION [dbo].[SplitParameterValues] (@InputString NVARCHAR(max), @SplitChar VARCHAR(5))
RETURNS @ValuesList TABLE
param NVARCHAR(255)
AS
BEGIN
DECLARE @ListValue NVARCHAR(max)
SET @InputString = @InputString + @SplitChar
WHILE @InputString!= @SplitChar
BEGIN
SELECT @ListValue = SUBSTRING(@InputString , 1, (CHARINDEX(@SplitChar, @InputString)-1))
IF (CHARINDEX(@SplitChar, @InputString) + len(@SplitChar))>(LEN(@InputString))
BEGIN
SET @InputString=@SplitChar
END
ELSE
BEGIN
SELECT @InputString = SUBSTRING(@InputString, (CHARINDEX(@SplitChar, @InputString) + len(@SplitChar)) , LEN(@InputString)-(CHARINDEX(@SplitChar, @InputString)+ len(@SplitChar)-1) )
END
INSERT INTO @ValuesList VALUES( @ListValue)
END
RETURN
END
Use the query below create a stored procedure to return all available values for Account parameter:
create PROCEDURE sp (@keyword nvarchar(50))
AS
SELECT AccountDescription
FROM DimAccount d
inner join (SELECT [param] FROM SplitParameterValues (@keyword,',')) s on d.AccountDescription like (s.[param]+'%')
In Report Designer, select Stored Procedure as the Query type for DataSet1, then select or type sp in the drop-down list as below:
By default, there is a parameter named keyword in the Parameters pane.
Add a multi-value parameter named Account in the report, then select “Get values from a query” option for Available Values as below:

Hmmm. This didn't work. I even re-booted, and Firefox still doesn't show the search engine.
It was actually an update to an earlier engine, and I foolishly removed the old version rather than just updating it.
Is there anything elsewhere (eg. the registry) that might be preventing this?

FAULT: COM Automation with long strings

Does anyone know if you can use COM Automation to call COM objects that return string longer than 255.
We have a problem in that when we call a method that returns a string longer than 255 chars it truncates it. The documentation says that you pass in a Varchar2.
I have tested the COM object from VB and it does not truncate it.

Hello eugene2,
I get the same problem.
Did you get a solution ?

JDeveloper, JPA named query String parameter with length of 1

Hi,
I use JDeveloper 11.1.1.2.0. and have the following table:
CREATE SEQUENCE COUNTRY_SEQ;
CREATE TABLE COUNTRY (
COUNTRY_ID NUMBER NOT NULL,
COUNTRY_NAME VARCHAR2(40),
COUNTRY_CODE CHAR(2) NOT NULL,
CONSTRAINT COUNTRY_ID_PK PRIMARY KEY (COUNTRY_ID)
INSERT INTO COUNTRY VALUES (COUNTRY_SEQ.NEXTVAL, 'Belgium', 'B');
INSERT INTO COUNTRY VALUES (COUNTRY_SEQ.NEXTVAL, 'Netherlands', 'NL');
COMMIT;
I made a JPA Entity with two queries:
@NamedQueries({
@NamedQuery(name = "Country.findAll", query = "select o from Country o"),
@NamedQuery(name = "Country.findByCountryCode", query = "select o from Country o where o.countryCode = 'B' or o.countryCode ='NL'")
The first works fine, gives back both B and NL. But the second gives back only NL. I have no clue why.
If I change 'B' to 'BE' both in the DB and the code, it works. If I change to 'b', it doesn't. So it seems that the problem comes with 1 char long Strings.
Is it an EclipseLink bug?
I use Oracle Database 11g Enterprise Edition Release 11.1.0.7.0. But
SELECT COUNTRY_ID, COUNTRY_NAME, COUNTRY_CODE FROM COUNTRY WHERE COUNTRY_CODE = 'B' OR COUNTRY_CODE = 'NL';
works in SQL*Plus.
Thx, Donat

Hi,
That's true, it uses value bindings while the values are hard coded. I use the default EclipseLink embedded into JDeveloper 11.1.1.2, with the default settings. The JPA bean runs in the default embedded WebLogic of JDeveloper. This might be a default setting of EclipseLink to use bindings for hard coded values.
Here is a fragment of Country.java:
@Entity
@NamedQueries({
//@NamedQuery(name = "Country.findAll", query = "select o from Country o")
@NamedQuery(name = "Country.findAll", query = "select o from Country o where o.countryCode ='B' or o.countryCode ='NL'")
public class Country implements Serializable {
@Id
@Column(name="COUNTRY_ID", nullable = false)
private Long countryId;
@Column(name="COUNTRY_CODE", nullable = false)
private String countryCode;
@Column(name="COUNTRY_NAME", length = 40)
private String countryName;
And I have a JavaServiceFacade.java:
public class JavaServiceFacade {
private EntityManagerFactory emf = Persistence.createEntityManagerFactory("EjbModel-1-Outside");
public JavaServiceFacade() {
public static void main(String [] args) {
final JavaServiceFacade javaServiceFacade = new JavaServiceFacade();
List<Country> countries;
countries = javaServiceFacade.getCountryFindAll();
for (Country country : countries) {
System.out.println(country.getCountryCode());
private EntityManager getEntityManager() {
return emf.createEntityManager();
/** <code>select o from Country o</code> */
public List<Country> getCountryFindAll() {
return getEntityManager().createNamedQuery("Country.findAll").getResultList();

SQL Prepared Statement with a string parameter including a colon

Hello everybody,
I'm recently experiencing a problem using Prepared SQL Statements if one of the parameter is a string containing a ":" (colon).
I'm able to insert a date (as a string) record using the format "hh:mm" into a MySQL database table but when I execute the query I cannot retrieve the record.
Does anyone know any problem with ":" character?
Replacing ":" with "." solves the problem...
Thanks a lot.
Edited by: 798883 on 29/09/2010 17:25

Huh?
One of the points in using PreparedStatements is that they handle the formatting for you. You shouldn't be setting dates with String values at all. Create a java.sql.Date (or timestamp or time as the case may be) and use the appropriate setXXX method of PreparedStatement. If you have String values then you can use SimpleDateFormat to parse them into dates.

Webservice: Problem passing long string 8k

Hi,
I have a webservice who receives a string parameter (xml). I send it a string shorter than 8 kb a no problem but when I send a long string longer than 8 kb, it has problems.
Do someone know how can I fix this?
Where can I modify this value?
regards.

Thanks for your recomendations, The problem is still there. I'm doing a POST.
I already did the same sample in CF9 and I don't have the problem there. The only diference is the that the CF9 is a physical server with Win Server 2008 R2 and the CF 10 is a virtual with WIn Server 08 R2.

Unable to bind portlet parameter with page parameter in webcenter portal

Hi All,
I am trying to bind portlet parameter with the page parameter so that I can ahieve some business requirements.
Here is what I did,
In my Portlet producer application:
1) Created standards based portlet (jsr 286) with view.jspx and edit.jspx with rest of the things being default.
2) In my portlet.xml created two parameters and assigned these parameters to the portlet created above.
3) In the view.jspx added couple of output label adf components in the page.
4) deployed this to integrated weblogic server.
In my WC portal application:
Created a new page and added the portlet to this page( WSRP connection already exists).
deployed portal application on integrated server.
In the edit mode of the page I added one page parameter(Param1) and some default (constant) value added.
What I want is this:
when Param1 value is One display first output label and
when Param1 value is Two display second output label.
I am using jdev 11.1.1.5.0 with integrated weblogic server.

There is no need to use page parameters for this.
You also have two types of parameters depending on what you want...
1) Preferences: these parameters can be used on a user based level. This means that users can personalize the portlets. When a user change the value of a preference, it is only applied for that specific user
2) Public parameters: these parameters are used to customize the portlet. The value you set in these parameter apply for all users.
I have made a simple example to show these two differences: http://www.yonaweb.be/PortletTest.zip
The portlet has 4 inputText on it. The first two can be set by specifying One or Two into the preference.
The other 2 inputText uses the value of the public parameter.
You should only deploy the portlet and consume it in a webcenter application. In the webcenter application, you don't need to do anything special. All is done in the portlet.
I am guessing you don't have written the code that will get the value of the parameter:
in case of a preference you will get the value by following code:
   PortletRequest request = (PortletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();
   PortletPreferences preferences = request.getPreferences();
   return preferences.getValue("outputparam", "One");In case of a public parameter (for customization instead of personalization) you use following code to retreive the value of a public parameter:
PortletRequest req = (PortletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();
String param = (String)req.getParameter("PublicParam");
if(param == null)
      return "Three";
return param;This code can also be found in the sample portlet application.

Problem with Long and BigDecimal DataType convertion

HI,
I have an application which talk to MySQL database with Spring JDBC layer and everything runs like a champ :)
Now I am converting the same application with the same DAO implementation to communicate with oracle database and I am having some trouble converting DataType from database to my java code.
For example before with MySQL I would convert any Integer coming from the database to Long datatype and it worked. Now it seems that Int datatype from oracle comes as a BigDecimal type.
I am thinking about two approaches writing an additional implementation to implement my dao interfaces or if there is some trickery that I can bypass doing that and work around these datatype incompatibility from MYSQL to Oracle.
I can also put bunch of try and catch statements and if fails with Long try with BigDecimal, but still don't buy it as the best solution.
Here use also code snippet:
User u = new User();
                    u.setObjectId((Long) m.get("oid"));//This works with MYSQL backend but not with Oracle so the raw object seem to be coming as BigDecimal datatype
                    u.setLogon((String) m.get("logon"));
                    u.setPassword((String) m.get("password"));
                    u.setName((String) m.get("uname"));
                    u.setCompany(companyDAO.getById((Long) m.get("cOid")));Any help will be appreciated.

Is there an easy way to convert a long string into an array?

I can convert a long string into a 1-d array by parsing and using build array, but I would like to know if there is a function to make this easier.
For example:
from/   aaaaaaaabbbbbbbbccccccccdddddddd         (string of ascii)
to/       an array that is 1-d with each element having eight characters
          aaaaaaaa
          bbbbbbbb
          cccccccc
          dddddddd
Thank you.
Solved!
Go to Solution.

Try something like this:
(If you can guarantee that the string length is an integer multiple of 8, you an drop the two triangular modes in the upper left. )

When using the Database Connectivity Toolset, reads and writes with long binary fields are incompatible.

I am trying to write LabVIEW Variants to long binary fields in a .mdb file using the Database Connectivity Toolset. I get errors when trying to convert the field back to a variant after reading it back from the database.
I next tried flattening the variant before writing it and ultimately wound up doing the following experiments:
1) If I use DB Tools Insert Data to write an ordinary string and read it back using a DB Tools Select Data, the string is converted from ASCII to Unicode.
2) If I use DB Tools Create Parameterized Query to do an INSERT INTO or an UPDATE operation, specifying that the data is BINARY, then read it back using a DB Tools Select Data,
the length of the string is prepended to the string itself as a big-endian four-byte integer.
I can't think of any way to do a parameterized read, although the mechanism exists to return data via parameters.
Presuming that this same problem affects Variants when they are written to the database and read back, I could see why I get an error. At least with flattened strings I have the option of discarding the length bytes from the beginning of the string.
Am I missing something here?

David,
You've missed the point. When a data item is flattened to a string, the first four bytes of the string are expected to be the total length of the string in big-endian binary format. What is happening here is that preceding this four-byte length code is another copy of the same four bytes. If an ordinary string, "abcdefg" is used in place of the flattened data item, it will come back as <00><00><00><07>abcdefg. Here I've used to represent a byte in hexadecimal notation. This problem has nothing to do with flattening and unflattening data items. It has only to do with the data channel consisting of writing to and reading from the database.
I am attaching three files that you can use to demonstrate the problem. The VI file c
ontains an explanation of the problem and instructions for installing and operating the demonstration.

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
