ojdbc14 में ojdbc6 अपग्रेड में ऑब्जेक्ट अक्रमांकन विफलता

** यदि आप जल्दी में हैं, तो बस अनुकूलित ojdbc6.jar फ़ाइल डाउनलोड करें और उसका उपयोग करें। आपको और कुछ नहीं करना है।

मेरे उत्तर का सारांश

सबसे पहले, नीचे दी गई कक्षाओं को डीकंपाइल करें।

• oracle.sql.DatumWithConnection.class

• oracle.sql.BLOB.class
फिर इन वर्गों में पुराने serialVersionUIDs जोड़ें। (पुराने संस्करण आईडी त्रुटि लॉग में उपलब्ध हैं)
उसके बाद कक्षाओं को फिर से संकलित करें।
आखिरकार, ojdbc6.jar को नई कक्षाओं के साथ अपडेट करें ताकि ojdbc लाइब्रेरी को अपग्रेड और कस्टमाइज़ किया जा सके। बस।

यदि आप मैन्युअल रूप से JAR बनाना चाहते हैं, तो नीचे दिए गए निर्देशों को पढ़ें और उनका पालन करें।

कस्टमाइज्ड जार को कैसे तैयार करें

सबसे पहले, नीचे दी गई कक्षाओं को ojdbc6.jar फ़ाइल में डीकंपाइल करें।

• oracle.sql.DatumWithConnection.class

• oracle.sql.BLOB.class

डीकंपाइल करने के लिए, आप "Java Decompiler" का उपयोग http://jd.benow.ca/ पर कर सकते हैं।

(ये वे वर्ग थे जो डेटाबेस से सहेजे गए BLOB ऑब्जेक्ट को पढ़ते समय परेशानी दे रहे थे।)

ग्रहण में एक साधारण जावा प्रोजेक्ट (फ़ाइल--> नया--> JavaProject) बनाएं या साधारण परियोजना मैंने बनाया है।

यदि आप एक नई परियोजना बना रहे हैं, तो उचित पैकेजिंग संरचना (oracle.sql) के साथ विघटित जावा फाइलें जोड़ें। साथ ही आपको इस परियोजना के निर्माण पथ में ojdbc6.jar फ़ाइल भी जोड़नी होगी।

फिर इन विघटित जावा फाइलों में पुराने सीरियलवर्जन यूआईडी जोड़ें। (इन जावा फाइलों को संकलित करने के लिए अतिरिक्त परिवर्तन भी आवश्यक हैं। कृपया नीचे अद्यतन जावा फाइलों को देखें)
```
 DatumWithConnection.java ->    private static final long serialVersionUID = 491462912477014233L;

 BLOB.java          ->  private static final long serialVersionUID = 2160152488501369185L;
```
उसके बाद, प्रोजेक्ट बनाएं और पुन:संकलित कक्षाएं प्राप्त करें।
अंत में ojdbc6.jar को नई कक्षाओं के साथ अपडेट करें ताकि उन्नत और अनुकूलित ojdbc लाइब्रेरी प्राप्त की जा सके। बस इतना ही

5.1 "अपडेटेड जार" नाम से एक नया फोल्डर बनाएं।

5.2 ojdbc6.jar फ़ाइल को उस फ़ोल्डर में कॉपी करें। D:\JARS\Updated JAR\ojdbc.jar

5.3 उस फोल्डर के अंतर्गत क्लास फाइल्स के लिए पैकेज स्ट्रक्चर बनाने के लिए दो नए फोल्डर बनाएं (\oracle\sql)

5.4 दोनों वर्ग फ़ाइलों को "sql" फ़ोल्डर में जोड़ें।
```
 D:\JARS\Updated JAR\oracle\sql\DatumWithConnection.class

 D:\JARS\Updated JAR\oracle\sql\BLOB.class
```
5.5 एक नई कमांडलाइन खोलें और निर्देशिका (सीडी) को उस स्थान पर बदलें जहां जार फ़ाइल स्थित है।
```
>cd D:\JARS\Updated JAR
```
5.6 नई क्लास फाइलों के साथ जार फाइल को अपडेट करने के लिए, कमांड लाइन में नीचे दिए गए कमांड का उपयोग करें।
```
>jar uf ojdbc6.jar oracle\sql\DatumWithConnection.class

>jar uf ojdbc6.jar oracle\sql\BLOB.class
```
5.7 अब आपके पास एक अनुकूलित ojdbc6.jar फ़ाइल है जो BLOB ऑब्जेक्ट्स के साथ काम करती है जिन्हें ojdbc14.jar के साथ क्रमबद्ध और सहेजा गया था

अपडेटेड जावा क्लासेस।
