You should be able to pass it in normally.
like if my class is Car and it takes a String parameter in the constructor.

var test = new Packages.com.acme.auto.Car( row["colName"] );

Andres,

I dont think thats going to be possible without changing the source for
BIRT.
There is code in BIRT to specifically convert < and > to display equivalent.
The reason for this is probally because, the data could cause problems for
the HTML output.

The function I believe is getEscapedStr in the HTMLWriter.java. If you have
to have this you may consider building your own BIRT and replacing this
call.

Andres,

There may be other ways of doing this, but you could modify
the getEscapedStr and comment the function out and return String s
that is passed in. I cant recomend this approach, because any changes in
the
future will require you to do this again.

Ok jason, I agree with you,
I thought other possible way but i dont know how to get it, i need to get
the column value and save it in a java var, but this must be done in the
class where i built the report.
Having the value stored in java var later i pass this value in the:
TextItemHandle tH = factory.newTextItem("");
th.setContent(valueStored);

What do you think?, Will be possible?

Thanks for help me, really i need to solve this problem because many data
are stored at format html, but this data must be displayed without code
html.

Andres,

If valueStored has < or > they will be replaced I believe with &lt etc.
I believe the call getEscapedStr gets called later.

Ok, lets see if i undertand you, the characters < or > from the data
obtained must be replaced by &lt etc, at runtime?

Having these data replaced should it be able to display in the report
without any problem?

Thanks for your time.

Andres,
The html writer does this so it can display < or > in the output and the
browser want interpret the code. This is main problem you are having. I
believe using the engine is not going to fix this for you.

Are you trying to get each row and then strip out the html?
If so take a look at the scripting reference in the help and look for the
Class DataRow under Understanding the data classes.

But I need the resultset like an java object, all the values i need will
store them into vars java.
Javascript is not useful for my problem by that i asked the way to obtain
the resultset or the values to be stored into java vars.

Andres,
I have a question into the developers on this. One other quick question
though.
Is the intent to get the rowset and rip out the html in them?
One other idea, may be to develop your own data control that does not call
the getEscapedStr
function. It could be identical in behavior as a data control, except for
that function. Look at the rotated text control for an example if this
sounds like something that would do what you want.

Jason,
All that I want is display the value of data that was stored at html format
but not the tags.

For example, I use jdbc connection and all the process until to get the
resultset, I iterate the resultset, get the value of some columns and pass
the value as parameter into the TextItemHandle.seValueExpr(parameter) and
this works.

By that i want to know how to get the resultset as jdbc resultset. I want
try this method because i dont want to modify or create something in BIRT.

Is posible to get it ?

Thanks.

Jason, I changed the class HTMLWriter and comment the function as you told
me before, but this change not works, the errors were the sames.

The text that the report try to display are:
Test Document 
-----------------------------
There are errors on the report page:
+ There are error(s) in TextData:textData

I use the class TextData,
TextDataHandle dataHandle = factory.newTextData("textData");
dataHandle.setContentType("html");
dataHandle.setValueExpr("row[\"textFormat\"]");

I thought that the purpose of this class will fix my problem.

What do you think?

Really help me, i dont find other way.

Andres,

I just added a in my sample data. I then opened the
HTMLWriter.java file and
went to the function and changed to something like this.
protected String getEscapedStr( String s, boolean whitespace)
{
return(s);
/* comment everything else out */
}

Obviously this is not elegant, but when I ran it through the debugger this
worked.
Once you have changed the source and it is built you will need replace the
or.eclipse.birt.report.engine.emitter.html package with the the new one that
you have just created.

Andres,
I dont see a way of getting the rowset this way.
I am checking with the developers, but I dont think this is possible.
It is possible within the javascript objects to get the rows though.

Jason,
Is possible pass the javascript object of resultset to java object?,
Because if i have the object with all the data i can use TextItemHandle and
the html will be interpreted.
