Image attribute in h:commandButton tag

If i use the image attribute in commandButton tag then the value can't be displayed.
How can the value be displayed when the image attribute is used?
<h:commandButton image="images/ex.gif" value="Add" action="#{MyBean.add}"/>
displays only the image with no value.

I think you cannot do that. Is that possible in simple Html? Why don't you wrtie on the image the value?

BUG?: preceding slash in h:commandButton image attribute

Hi,
when I'm creating a <h:commandButton> and add an image to it, I always have the same 'problem' when I use the intellisense on completing the image attribute. It happens in the Studio Edition Version 10.1.3.0.4.
If I enter <h:commandButton image="mslast.gif"> or pick this image from the list in the property inspector, the attribute will always change to "/mslast.gif".
If I would then run the .jsp pages, the images are not displayed. They will only be displayed if I manually correct the attribute by deleting the preceding slash.
Just for the record, the images and the .jspx files are in the same folder at the same level.
kind regards

How can I apply new attributes to a table-Tag in an JEditorPane?

I'm using a JEditorPane as a base for a small HTML-Editor. The manipulating of the attributes of an image-tag such as href works fine. But now I want to add the width-attribute to an table-tag.
The result: Nothing in the table-tag, but other strange things (width is set to any TD oder in every cell a new table is added.
How can I do this? Any suggestions??
Thanks.

Did you ever solve this problem?
I can manipulte the tags and character styles, but the manipulation of <td>, <div> and other standard tags I cannot figure out.
Please let us know, [email protected]
By the way:
If you have only a width tag in your images, does it resize proportionaly, as in a normal browser or is the height taken from the original picture, as it happens with me?
This is quite nasty, since I do not know the original picture sizes.

How to set an attribute of a HTML tag with a value in the Servlet

I have a HTML page and a Servlet.
The HTML page sends a request to the Servlet.
The Servlet has to read the contents of the HTML page. When the Servlet encounters the body tag it should set the bgcolor attribute of the body tag with a string(For eg.a string called color with a value blue) in the servlet.
After doing this the Servlet has to update the original HTML page with the changes (in the body tag).
I need a help on this.

Hi sangee,
you could get what you want to do by using a Java Server Page instead of both a HTML page and a Servlet.
I should code something like this:
<%Strung color="yourColor"%>
<html><head><title></title></head>
<body bgcolor="<%=color%>
</body>
</html>

I have done exactly that in one of my applications.
I have extracted the image from the database as a byte array, and displayed it using a servlet.
Here is the method in the servlet which does the displaying:
(since I'm writing one byte at a time, it's probably not terribly efficient but it works)
 private void sendImage(byte[] bytes, HttpServletRequest request, HttpServletResponse response) throws IOException {
 ServletOutputStream sout = response.getOutputStream();
 for(int n = 0; n < bytes.length; n++) {
 sout.write(bytes[n]);
 sout.flush();
 sout.close();
 }Then in my JSP, I use this:
<img src="/path-to-servlet/image.jpg"/>
The name of the image to display is in the URL as well as the path to the servlet. The servlet will therefore need to extract the image name from the url and call the database.

Workflow problems: Import selection, 9 keywords in list?, Exporting image attributes...

I have a few problems incorporating Lightroom into my work flow.
Is there a way to:
Select recursive directories when importing photos from disk without
a copy. Currently, I can only choose files directory(folder) by
directory.
Get more than 9 keywords in a shortcut list.
Add photos from a previously accessed CF card to a catalog in a short
time.
Currently it takes about the same time as loading a card from scratch.
Export image attributes to text file
(filename followed by keywords, rating...)
Basic principles of my work flow:
1. Flash card is used until contents roughly matches the archive media
size.
This means a 1GB card fills to 700MB after deleting rejects, and
a 4GB card will easily fit on a DVD.
2. Photos on card are categorized and rated/rejected/deleted one or more
more times while the card is being filled. This results in:
-Copies of retained images to the categorized directory structure on the
computer.
-Rejects deleted from card, and not appearing on the computer
-Category, and rating information for each image in an easily parsed
list.
3. Post processing is done and printing is done on highest rated images
in each category.
For example:
Day 1: start with a blank 4GB CF card, and shoot 1.5GB for customers A and
B.
Customer A has 8 subjects a,b,c,d,e,f,g,h; Customer B has 12
subjects
a,g,i,j,k,l,m,n,o,p,q,r. Note that some names for customers A and B
are the same. That night, I delete rejects off the card down to
800MB,
and copy the saved images to the directory structure corresponding
to each customer on the computer. Then a list is printed out to show
an image+rating list for each subject. Notes are made for each
"weak"
subject, so I know who to focus on in the next day of shooting.
Note I may have needed to do some minor post processing to determine
rejects and rating.
Day 2: I shoot 9 subjects for customer A: a,b,c,d,e,f,g,h,s, and 12
subjects for customer C: j,m,q,t,u,v,w,x,y,z,aa,bb. Similar culling,
sorting, and copying is done to Day 1.
Day N: CF card is full, so contents is written to a DVD, then card is
erased.
Day M: Sufficient counts of good images are obtained for Customer A, so
Final post processing is done, and prints are made.
My initial experimenting with Lightroom shows it has potential to streamline
the above work flow, but a few key hurdles have kept me from implementing
it. I have made some assumptions about the tool in the following description,
so the best help for me would first to point out what assumptions are incorrect
It looks like "import from device..." only allows a copy from the CF card.
A copy would mean once images were rejected in the catalog, it would be
out of sync. with the CF card. So "import photos from disk..." looks
to be the only way to accomplish principle 1 above. *[minor problem a]* I saw
no way to import the information from the CF cart recursively in this
mode. I had to choose the files in groups one directory (folder) at
a time. When I imported from device, I could grab the whole CF card,
even though it did a copy. Note another reason I can't copy the CF card
to the catalog is that the reject/delete operation would not free-up any
CF card space for the next shoot.
Rejecting, rating, and categorizing (with keywords) worked easily with
Lightroom, but *[minor problem b]* it appears the keyword shortcut list is
limited to 9 entries. Given customers can have more than 9 subjects,
it would be useful if this could be expanded, even if I implement some sort
of keyword hierarchy. I suspect the camera will complain about a bad file
format if I change any of the files on the CF card, but it looks like
the sidecar files on the computer disk allows me to "modify" images so
I can get a correct rating without actu

Info attribute in jsp page tag

Is anybody else experiencing a problem with the info attribute in the page
 tag? None of my pages with the info attribute will compile. Every one
 generates a 'Duplicate method declaration/definition' error because the
 Weblogic JSP compiler is generating two 'getServletInfo' methods if the
 attribute is included. If I take the info attribute out they compile fine.
 Here's a sample tag:
 <%@ page info="myfile.jsp (c) 2000, InvoiceLink Corporation. All Rights
 Reserved."
 import="java.util.*,com.invoicelink.invoicer.util.*,java.text.*,
 com.invoicelink.invoicer.data.*"
 errorPage="./ErrorPage.jsp"
 contentType="text/html; charset=ISO-8859-1"
 buffer="8kb" autoFlush="true"
 isThreadSafe="true"

Class as an attribute name in JSP tag file

I just ran into an issue where I was writing a custom tag to generate a specific set of HTML elements, and wanted to be able to use CSS the same way I had before refactoring it into a tag. So, I included 'class' as an attribute in the custom tag file and deployed.
On Glassfish v3, this generated a bunch of JasperExceptions in the Javac compilation, complaining about <identifier> expected and reaching the end of file while parsing. I tracked it down, of course, to the use of 'class' as an attribute name, which was reduced to a servlet class defining:
public String getClass() {
return this.class;
public void setClass(String class) {
this.class = class;
}I'm curious -- which part of the process messed up here? Is "class" a valid identifier under the Java EE spec, and the translation should have used something like setClass_(String class_)? Or is it invalid, and Netbeans didn't know to mark it as an error before it tried to deploy? (And, of course, that I missed that in the spec, making it my fault.) I couldn't find anything specifically saying that reserved words couldn't be used as JSTL identifiers, so my gut is that the parser messed up. Also, I found a bug report about it for an alternate web container, but no mention of it in the bug trackers for Glassfish, Tomcat or Jasper.
Where's the blame?

stdunbar wrote:
I think that Netbeans messed up. getClass() is, of course, defined on Object and class is a Java keyword.What's to stop the compiler from recognizing that "class" would be a problem and mapping it to an alternate name behind the scenes?
This is the only documentation I turned up. Maybe this says it's invalid:
Java EE SpecThe unique name of the attribute being declared. A translation error results if more than one attribute directive appears in the same translation unit with the same name.A translation error results if the value of a name attribute of an attribute directive is equal to the value of the dynamic-attributes attribute of a tag directive or the value of a name-given attribute of a variable directive.

Can I parameterise image attributes?

I am displaying an image in my BI Publisher report, sourcing it from a blob.
<xsl:if test="not(FILENAME='')">
<fo:instream-foreign-object content-type="image/gif" height="5cm" width="5cm">
<xsl:value-of select="LOGO_IMAGE"/>
</fo:instream-foreign-object>
</xsl:if>It works fine, until some of the images get larger heights or widths - I haven't figured out the relation yet, but I thought if I could parameterise the height and width properties, perhaps I could make the report happier.
Is there a way to pass XML values into these fields, such as something like
<xsl:if test="not(FILENAME='')">
<fo:instream-foreign-object content-type="image/gif" height="SQL_HEIGHT" width="SQL_WIDTH">
<xsl:value-of select="LOGO_IMAGE"/>
</fo:instream-foreign-object>
</xsl:if>Which doesn't work, but I thought there might be a way if I got the syntax right...
Thanks.
Scott

I haven't successfully parameterised either those image attribute fields, or the usage of
<fo:external-graphic src="http://my_url:7021/i/loadingAnimation.gif"/> In efforts to do something constructive I tried to parameterise the external-graphic reference instead - since I can't seem to generate anything larger than 32kb worth of XML.
I tried variations of the following, with no success
<?IMAGE_URL?> -- displays the url text
<fo:external-graphic src="?IMAGE_URL?"> -- displays nothing
<fo:external-graphic src="IMAGE_URL"> -- displays nothing
<fo:external-graphic src=?IMAGE_URL?> -- displays nothing
<fo:instream-foreign-object content-type="image/gif">
<xsl:value-of select="IMAGE_URL"/>
</fo:instream-foreign-object> -- displays nothing, but did expand area consumed
Is there syntax I should be using instead, or is this not possible?
Cheers.

Attribute onselect invalid for tag selectOneMenu according to TLD

Hi All
I am seeing the error message "Attribute onselect invalid for tag selectOneMenu according to TLD" with html_basic.tld version 1.0 even though the tag and attribute are present in the TLD. The error occurs on Windows XP in Jboss 4.0.2. I don't see the error on Linux.
I'd appreciate any help.
Thanks
Murthy

Hi Raymond
Found that Jboss was loading html_basic.tld from an unknown jar. When I set the URI in the JSP to the TLD file placed in WEB-INF/lib, the error went away.
Changed
<%@ taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<%@ taglib prefix="h" uri="WEB-INF/lib/html_basic.tld"%>
Wonder in which jar the TLD lies.
Thanks for your help

Problems for retrieving image attributes

Hi,
I am a new user for Oracle interMedia and i have following problem.
I have wroten ein java programm to retrieve the image properties. At First, the images (jpg, tif) are stored as BLOB in the table, then i use the function setProperties() to set the image attributes.
PreparedStatement pstmt = con.prepareStatement("INSERT INTO btable VALUES(?, ORDSYS.ORDImage.init())");
for (int ef=1; ef<=anzahl_summe; ef++){
pstmt.setInt(1, ef);
pstmt.execute();
OracleResultSet rs = (OracleResultSet)stmt.executeQuery("SELECT * FROM btable WHERE bid = " + ef + " FOR UPDATE");
while(rs.next()) {
OrdImage imgObj = (OrdImage)rs.getCustomDatum(2, OrdImage.getFactory());
imgObj.loadDataFromFile(f_location[ef]);
imgObj.setProperties();
OraclePreparedStatement orpstmt = (OraclePreparedStatement)con.prepareStatement("UPDATE btable SET bild = ? WHERE bid =" + ef);
orpstmt.setCustomDatum(1,imgObj);
orpstmt.execute();
orpstmt.close();
Now if i use the functions getHeight(), getFormat(), ... for querying the properties, i will get just only the values for the image height, width and size. The other attribute values i get either null or ???. I don't understand why. The Bildforamte(jpg, tif)are supported by Oracle.
Can you tell me what shall i do?
thank you very much and greeting from germany

Hi larry,
thank you for your help. I have set autocommit off and commit in the end of the programm. I think, that is not a problem.
I use the following table:
CREATE TABLE bildtable_intern(bild_id int PRIMARY KEY not null, bild ORDSYS.ORDImage)

conn.setAutoCommit(false);
public void bildmessung(Connection con) throws Exception{

for (int ef=1; ef<=10; ef++){
pstmt.setInt(1, ef);
pstmt.execute();
OracleResultSet rs = (OracleResultSet)stmt.executeQuery("SELECT * FROM bildtable_intern WHERE bild_id = " + ef + " FOR UPDATE");
while(rs.next()) {
OrdImage imgObj = (OrdImage)rs.getCustomDatum(2, OrdImage.getFactory());
//I have also tried to use loadDataFromInputStream() and loadDataFromByteArray()
imgObj.loadDataFromFile(f_location[ef]);
imgObj.setProperties();
OraclePreparedStatement orpstmt = (OraclePreparedStatement)con.prepareStatement("UPDATE bildtable_intern SET bild = ? WHERE bild_id =" + ef);
orpstmt.setCustomDatum(1,imgObj);
orpstmt.execute();
orpstmt.close();
pstmt.close();
retrieveattr(con);
public long retrieveattr(Connection con) throws Exception{

while (rs.next()){
OrdImage imgObj = (OrdImage)rs.getCustomDatum(2, OrdImage.getFactory());
System.out.println("bild_id = " + rs.getInt(1));
System.out.println("bild_height = " + imgObj.getHeight());
System.out.println("bild_width = " + imgObj.getWidth());
System.out.println("bild_size = " + imgObj.getContentLength());
System.out.println("bild_format = " + imgObj.getFormat());
System.out.println("contentformat = " + imgObj.getContentFormat());
System.out.println("compressionformat = " + imgObj.getCompressionFormat());
System.out.println("mimetyp = " + imgObj.getMimeType());
public static void main(String[] args) throws Exception{
//call the methode connect()
con.commit();
con.close();
I try again, but i get always only the values for image height, width and contentlength. Can you tell me, what ist wrong with this programm?

Using WEB Output HTML Gallery and uploading using ftp upload the HTML page views correctly but images only display the alt tag?

Using WEB Output HTML Gallery and uploading using ftp upload the HTML page views correctly but images only display the alt tag in the browser window?

After a little investigation, I discovered that PNGs also do not render correctly in IE7 in similar circumstances.
I ended up using Levels in Photoshop to bring the output blacks up to "5", saved the images as PNGs, modified the HTML from .jpg to .png, and that seems to have covered up the problem well enough.
By the way, I did confirm that IE8 beta 2 renders the images correctly.
