After further investigation I nailed the problem to the
XStorable.storeAsUrl() method. It seems, that the method ist not
executing properly but isn't throwing an exception either. The debugging
messages are exactly the same for all executes , except for the crashing
one where logger.debug("Store as URL finished") is not executed. But the
surrounding catch block to get the com.sun.star.io.IOException is not
executed either. So no error message for me :/ .
try
{
if (changeIdentity)
{
logger.debug("Store as URL. Property is:"+property[0]);
// property[0] = new PropertyValue(); property[0].Name =
"Overwrite"; property[0].Value = new Boolean(true);
logger.debug("Filename ist: "+fileName); // generated
file name
logger.debug("has Location
"+this.xStoreable.hasLocation()); // false
logger.debug("is read only
"+this.xStoreable.isReadonly()); // false
this.xStoreable.storeAsURL(fileName, property);
logger.debug("Store as URL finished"); // on crash, this
line is not beeing executed, but the catch block is neither executed
}
else
{
logger.debug("Store to URL");
// storeTo behält die Identität des Dokuments bei,
entspricht
// also dem Export
this.xStoreable.storeToURL(fileName, property);
logger.debug("Store to URL finished");
}
}
catch (IOException ioe)
{
throw new OpenOfficeException(ioe); // is never thrown even
tough storeAsURL seems not to execute properly.
}
The file is indeed saved at the specified location given to
storeAsUrl(), but it contains absolultely no data. I've also noticed,
that the problem only arises if I did embed a graphic into the document
at the last(crashing) try. Even though tests like the above NEVER failed
what would suggest, that the embedGraphic-Method and the saveAs-method
are alright. And in my application the embedGraphic-Method is beeing
executed properly as well before the crash.
Quick-Test for embedGraphic and saveAs method:
for(int i = 0; i < 500; i ++)
{
con = fac.createOpenOfficeConnection();
doc = new TextDocument(con,
"file:///m/quark/steb/s3/tmp/PB.odt");
doc.embedGraphic("file:///m/quark/steb/s3/tmp/test2.jpg",
doc.getCursorByPlaceHolder("hier", false));
doc.appendDocument("file:///m/quark/steb/s3/tmp/test2.odt");
doc.appendDocument("file:///m/quark/steb/s3/tmp/test2.odt");
doc.saveAs("file:///m/quark/steb/s3/tmp/append"+i+".odt");
// calls the above posted code
doc.close();
con.close();
}
the embedGraphic Method:
public void embedGraphic2(String graphicURL, XTextCursor cursor)
{
logger.debug("embedding graphic "+graphicURL);
XText xText = cursor.getText();
// 1st step: Insert graphic object into the document as a link
//
try
{
XTextContent xImage = (XTextContent) UnoRuntime
.queryInterface(
XTextContent.class,
xMultiServiceFactory
.createInstance("com.sun.star.text.TextGraphicObject"));
// Querying for the interface XTextContent on the GraphicObject
XTextContent xTextContent = (XTextContent) UnoRuntime
.queryInterface(XTextContent.class, xImage);
// Replace the selected text with the image content
xText
.insertTextContent(cursor, xTextContent,
true);
// Querying for the interface XPropertySet on GraphicObject
//
http://api.openoffice.org/docs/common/ref/com/sun/star/text/TextContent.html
XPropertySet xPropSet = (XPropertySet)
UnoRuntime.queryInterface(
XPropertySet.class, xImage);
// Setting the anchor type
xPropSet.setPropertyValue("AnchorType",
TextContentAnchorType.AS_CHARACTER);
// Setting the graphic url
//
http://api.openoffice.org/docs/common/ref/com/sun/star/text/TextGraphicObject.html
xPropSet.setPropertyValue("GraphicURL", graphicURL);
// 2nd step: create a bitmap container to hold graphic
permanently
// inside the document
//
XNameContainer xBitmapContainer = (XNameContainer) UnoRuntime
.queryInterface(XNameContainer.class,
xMultiServiceFactory
.createInstance("com.sun.star.drawing.BitmapTable"));
// helper-stuff to let OOo create an internal name of the
graphic
// that can be used later (internal name consists of various
// checksums)
MessageDigest md = MessageDigest.getInstance("MD5");
md.update(graphicURL.getBytes(), 0, graphicURL.length());
String internalName = new BigInteger(1,
md.digest()).toString(16);
xBitmapContainer.insertByName(internalName, graphicURL);
String internalURL = (String) (xBitmapContainer
.getByName(internalName));
// replace external URL with internal URL
xPropSet.setPropertyValue("GraphicURL", internalURL);
// remove unnecessary object reference
xBitmapContainer.removeByName(internalName);
logger.debug("Finished embedding graphic");
}
catch (IllegalArgumentException e)
{
e.printStackTrace();
}
catch (UnknownPropertyException e)
{
e.printStackTrace();
}
catch (PropertyVetoException e)
{
e.printStackTrace();
}
catch (WrappedTargetException e)

Did anyone ever encounter such a problem with storeAsUrl()? Or could you
think of any circumstances where it could fail without throwing the
IOException?
