I am trying to insert images selected by a user from an applet. I can insert images over 100K without any issue. When I select an image from the browser that is over 1MB I get an IOException when trying to write to the DB.
I have done a lot of research on this issue and I have searched the forums before making this post.
The database is 10g and I am using Oracle 10.1.0.5 Type 4 driver in classes12.zip provided by Oracle. This is standard driver by my company for our setup and I cannot switch to the Type 3 ojdbc14 driver.
I am also using WebSphere in RAD 7.0.0.5
I am using WebSphere's connection pooling which is setup via the plig-in tag in my struts-config file. I use the JNDI lookup to get the transaction manager. This has been working fine so far.
I am using hibernate 3.3.1
I used the approach to inserting blobs into the database discussed at:

This is my Java Object:
Code:
public class CaseStudyPictureBook implements java.io.Serializable{
private static final long serialVersionUID = 3041874046189597595L;
private Long pictureId;
private Long caseStudyId;
private String description;
private byte[] picture;
private String createdBy;
private java.sql.Date createdDate;
private String modifiedBy;

private CaseStudyPictureCategoryLookup csStatus;
public CaseStudyPictureBook(){
super();
}
public Long getCaseStudyId() {
return this.caseStudyId;
}
public void setCaseStudyId(Long caseStudyId) {
this.caseStudyId = caseStudyId;
}
public String getCreatedBy() {
return this.createdBy;
}
public void setCreatedBy(String createdBy) {

}
public void setDescription(String description) {
this.description = description;
}
public String getModifiedBy() {
return this.modifiedBy;
}
public void setModifiedBy(String modifiedBy) {
this.modifiedBy = modifiedBy;
}
public java.sql.Date getModifiedDate() {

}
public void setModifiedDate(java.sql.Date modifiedDate) {

}
public Long getPictureId() {

}
public void setPictureId(Long pictureId) {

}
public CaseStudyPictureCategoryLookup getCsStatus() {

}
public void setCsStatus(CaseStudyPictureCategoryLookup csStatus) {
this.csStatus = csStatus;
}
public byte[] getPicture() {
return this.picture;
}
public void setPicture(byte[] picture) {
this.picture = picture;
}
/** Don't invoke this. Used by Hibernate only. */
public void setImageBlob(Blob imageBlob) {
this.picture = this.toByteArray(imageBlob);
}
/** Don't invoke this. Used by Hibernate only. */
public Blob getImageBlob() {
return Hibernate.createBlob(this.picture);
}
private byte[] toByteArray(Blob fromBlob) {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
try {
return toByteArrayImpl(fromBlob, baos);
} catch (java.sql.SQLException e) {
throw new RuntimeException(e);
} catch (java.io.IOException e) {
throw new RuntimeException(e);
}
finally {
if (baos != null) {
try {
baos.close();
} catch (java.io.IOException ex) {
ex.printStackTrace();
}
}
}
}
private byte[] toByteArrayImpl(Blob fromBlob, ByteArrayOutputStream baos) throws SQLException, IOException {
byte[] buf = new byte[4000];
InputStream is = fromBlob.getBinaryStream();
try {
for (;;) {
int dataSize = is.read(buf);
if (dataSize == -1)
break;
baos.write(buf, 0, dataSize);
}
} finally {
if (is != null) {
try {
is.close();
} catch (java.io.IOException ex) {
}
}
}
return baos.toByteArray();
}
}
This is my mapping file:
