Image upload using Java API

Question

Hi all,
I am trying to upload an image into MDM repository using the Java MDM4J API. I have referred to the earlier posting in this forum for the same problem I am not able to add images into Catalog thru java API. However I am working on SP3 version of MDM software and looks like the Images table structure changed a bit and the code in the earlier posting isn't working.
I am getting an error code <b>-5586944</b> and the message that gets printed on the console is
<i>a2i.core.StringException: AddRecord error
     at a2i.common.CatalogData.AddRecord(Unknown Source)
     at a2i.common.CatalogData.AddRecord(Unknown Source)</i>
Here is the code that I am using to upload the image
String filePath = "C:\temp\Sunset.jpg";
File file = new File(filePath);
byte[] bytes = new byte[(int) file.length()];
try{
     //read byte from file, and set the large data
     FileInputStream inputStream = new FileInputStream(file);
     inputStream.read(bytes);
     mdmFields.Add(new A2iField("Data ID", new Value(bytes)));
}catch(IOException ioex){
     ioex.printStackTrace();
int dataGroupId = 0;//Hardcoded it to 0. There is one group already in the repository
mdmFields.Add(new A2iField("Data Group ID", new Value(dataGroupId)));
//adding the name
mdmFields.Add(new A2iField("Name", new Value(file.getName())));
mdmFields.Add(new A2iField("Original Name", new Value(file.getName())));
//adding OrigLocationId
int origLocationId =0;
try{
     origLocationId = catalog.AddDataLocation(filePath, 0, DataLocationType.ComputerLocation);
     System.out.println("Location id generated is " +origLocationId);
}catch(StringException ex){
     System.out.println("Error while generating the location id");
     ex.printStackTrace();
mdmFields.Add(new A2iField("Original Location ID", new Value(origLocationId)));
try {
     //adding the image to the "Images" table
     int newImageId = catalog.AddRecord("Images", mdmFields, 0, 0);
} catch (StringException e) {
     // TODO Auto-generated catch block
     System.out.println("Error while adding the image record " + e.GetErrorCode() + "  " + e.GetRCMessage(e.GetErrorCode()));
     e.printStackTrace();
I am not able to figure out what is causing the problem. Any ideas would be greatly helpful. Thanks in advance.

Hi Mausam,
Thanks for your help. However, the problem doesn't seem to be going.
I printed the records in the <b>Data Groups</b> table using a program to find the record ids that are already existing. My Data Groups table has 3 records. Here are the values.
ID :1 Value :MyGroup
ID :2 Value :Group2
ID :3 Value :Group3
I tried passing all the above 3 values (1,2,3) as input to the <b>Data Group ID</b> field. However, this time, I am getting a different error code this time
Error while adding the image record -2147483647  No message for RC (0x80000001)
a2i.core.StringException: AddRecord error
     at a2i.common.CatalogData.AddRecord(Unknown Source)
     at a2i.common.CatalogData.AddRecord(Unknown Source)
     at images.MyImageUpload.uploadImage(MyImageUpload.java:82)
The error code <b>2147483647</b>  from the javadocs says <b>RC_BADPARAM</b>. Not able to figure out what exactly is causing the problem with Data Group ID.
Any ideas or pointers to solve this would be greatly helpful. Thanks in advance.
