JSP: how to display a String that has HTML

I'm reading contents of a file and want to display them on the JSP page. However, the contents may have HTML tags in them as well. Right now it just displays the String HTML tags, not actually rendering them. How do I display the String so the HTML tags are actually used?
So if the String has "Hello"
I want it to show up in the webpage with the word Hello bolded, not the actual and tags displayed.

Something is escaping the file contents. Perhaps if you dropped a few
hints about how you are actually doing this.

How to display a field that has more than 136 char length in ALV GRID

Hi Experts,
I have an issue and need to solve ASAP.
I want to display a text of length 400 character in a particular column in ALV GRID DISPLAY. After executing the report it is displaying only 136 length char in the output and when I download the report to an excel it is showing only 255 characters, but my field length is almost 400 char and want to display in the report output.
I checked in SDN and didnt get any answers which will solve this.
Please help me to complete this issue.
Thanks
Retheesh

Currently I'm in a same problem with you.
And this is what I found
Size of data fields: While the list-based ALVList can display only tables of up to 90 columns, the control-based *ALVGrid and ALVFullscreen have a limitation of 128 characters per data cell.*
So it means that maximum for alv grid is only 128.
Please refer to this documentation
[https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/4544e790-0201-0010-c29c-e46c389f5a96]
you can find the statement above in page 5.
Please let me know if you have another solution, because I would like to see it too.
Thanks

Dynamically Setting a Variable from a Connection String that has been set by a Config File

Hi Guys
I'm setting up a Master / Slave (Parent / Child) dtsx environment but I'm unable to work out how to dynamically set a variable in the Master dtsx from a connection string that has had its value set by a config file. I'm sure it's possible.
Below is the what I'm hoping to achieve. I've set up everything apart from the highlighted section.
Any ideas?

First, what version of SQL Server are you using?
You could switch the problem around. You could set the value of a variable from the config file, then it is easy to use that variable as the connection string source for your connection manager. At the same time you can use a parent variable
configuration to map that variable to variables in your child package.

How do I find music that has been uploaded to iTunes from a purchased CD and iTunes is "unable to find the original file?" I no longer have the CD. I have tried all the usual methods of looking in my iTunes library and through Find. No Luck.

How do I find music that has been uploaded to iTunes from a purchased CD and iTunes is “unable to find the original file?” I no longer have the CD. I have tried all the usual methods of looking in my iTunes library and through Find. No Luck.

Backup drive?
Subscribe to iTunes Match?
If neither of the above and you don't have the CD and can't find your tracks on the computer then they you're stuck. A file recovery utility will cost $100, plus another $100 for an external drive to which to resue the files, and may not even work. You can buy a lot of CDs for $200.

How to get PDF file that has been transformed into docx into my filing system so I can work on it???

How can I get the PDF file that was transformed into a docx file into my filing system to be able to work on it and translate it as the customer requested?

THanks for your reply.
Well what happens is I bought the program. It gives you a button to click,
you log in and then a box opens up asking you to select the file, I go into
my filing system (in Windows explorer) select the file, and the program
converts it into docx, my choice. I can read it there and when I try to
copy and paste it into my file where the PDF version is saved, it behaves
like an "image", and I can't save it.... or it saves likes something you
save on the internet, so you have to go into internet every time you want
to see it. I have also pressed any amount of buttons to see if it will
give me the option to save it any other way, and have found nothing. What
I would need is a file in docx.format that I can edit. People send me
things in PDF and sometimes I can just copy it off the PDF file and save it
in WOrd, then I can translate it for them. But sometimes the PDF file
doesnt allow me to copy the text. If it is in image form, I cannot work on
it. It means printing it, so I can copy type it into Word... and for that
I certainly wouldnt need to buy a program. Its just double the work and
ends up that the job takes twice as long.!
Sorry if I am a bit dumb with informatics. But I simply could not find
any way whatever to copy the PDF file that was transformed into Word, in a
format that would enable me to edit it.
Kindest regards,
Margery

TS4036 How do I access content that has been backed up to iCloud? I no longer have an iphone, but want to access the music/pictures I've stored to the cloud. When I logged into iCloud, there was no tab or option to view store content. Please help.

How do I access content that has been backed up to iCloud? I no longer have an iphone, but I want to access the music/pictures I've stored to the cloud. When I logged in to iCloud, there was no tab or option to view content. Please help.

Without an iPhone or iPod Touch to restore the backup to, you cannot access the camera roll photos stored in the iCloud backup. Signing into the account on your computer and enabling photo stream will only allow you to access photo stream photos from the last 30 days, and any shared stream you were subscribed to.
You can redownload purchased music in iTunes on your computer as explained here: http://support.apple.com/kb/ht2519.

How to display RTE item in a HTML region

I have a process that is populating a hidden item with a RTE item from another page. I need to display this in its formatted state. I am using an HTML region to display this item but the page shows HTML tags instead of rendering them. I have tried both options under html region (escape special characters and plain HTML text).
Can someone please help me to display this formatted RTE item on a page? Btw...I am using APEX 4.0.
Thanks.

How to get the row that has failed due unique constriant voilation

Does any body knows how I can get the column values for rows that has failed on unique contriant voilation, I am using 10gr2.
Also we don't have license for shadow table error logging, otherwise I could have gotten the row from there.
Any help will be highly appreciated.
Thanks,
Ravi

Hi Ravi,
Prior to OWB 10.2.0.3 you can use the DML error logging features only for the mappings which runs
in ROW based mode.
But from OWB 10.2.0.3 onwards DML error logging features can be used for SET based mappings also.
You can refer the following Metalink notes for the same

How can I save music that has been sent to me via email on my iPad.?

How can I save music to my iPad that has been sent to me in an email? Please help

You can't save it to the Music app directly on the iPad, you will need to see if there are any third-party music apps in the store that you allow you to copy music from Mail to them. For the Music app then only way to get music into it is via the iTunes store app directly on the iPad and by syncing from your computer's iTunes.

How to unlock macbook pro that has been remote locked from the icloud

how do you unlock the macbook pro that has been remotly locked from the icloud because i forgot my password

This question should NOT be answered. Using Find My Mac to lock one's computer is a personal security measure for those whose Macs have been lost or stolen and may be in the hands of criminals. Publicly posting instructions for defeating that measure would be tantamount to abetting theft.
If you have foolishly locked your own computer and need to unlock it, take it to an Apple Store. Be prepared to prove you are its rightful owner.

How to print a form that has scrollable boxes data?

I have developed a form that individuals can fill out a box that is scrollable to fit a certain number of letters. On the screen after the form has been completed I want to print out the form but the scrollable box only prints what is seen on the screen rather than what has been typed in the entire box. How can I get a printout of this form with all the information that is in the scrollable box?

AcroForms do not have dynamic fields. One could use templates to spawn a new page that has a larger form field with the same name. Another approach would be to export the data to an FDF and then have a different copy of the form with much larger fields for those fields that are over flowing and import the FDF into that form.

How To display a table that resides in the database via JFrame.

Hi,
I need to display the contents that present in the table that resides in my database.
Scenario:
Im having Main frame window, in that im having a button, while clicking that button a new JFrame should be opened & it should display all the rows & cols of dat table that resides in my DB.
I have no prob in opening a new JFrame during a button click, but i dont knw how to display table in the table format.
I tried JTable but i dont know how to pass the data into the JTable.
Kindly help me out!!!

JTable relies on a TableModel to deliver data. You have several ways of providing this data:
- Read it into either a Vector of Vectors (list of rows containing list of columns) or an Object[][] and create the JTable while passing the data.
- Create a javax.swing.table.DefaultTableModel, pass it to the JTable as a model, configure it and call addRow() in order to add rows.
- Create a custom table model class; see javax.swing.table.AbstractTableModel for a convenient base class
