Error while using Jsoup API inside sling servlet

[sankarr26533925]

Hi,

I am getting the below error while using Jsoup  API inside sling servlet. I have added my dependency in pom.xml.

Caused by: org.apache.sling.api.resource.PersistenceException: Resource at 'Servlet' is not modifiable.
    at org.apache.sling.servlets.post.impl.helper.SlingPropertyValueHandler.setProperty(SlingPropertyValueHandler.java:153)
    at org.apache.sling.servlets.post.impl.operations.ModifyOperation.writeContent(ModifyOperation.java:411)
    at org.apache.sling.servlets.post.impl.operations.ModifyOperation.doRun(ModifyOperation.java:101)

Kindly provide your thoughts on this.

See this community article - it has an AEM package that uses this API:

This error doesnt looks like it is caused by JSoup. Can you post the entire logger or your servlet here...

Have used Jsoup in CQ5 before.

Simply added this to pom.xml:

<dependency> <groupId>org.jsoup</groupId> <artifactId>jsoup</artifactId> <version>1.7.3</version> </dependency>

Later used it as:

Jsoup.parse(result);

How is Jsoup html parsing library related to persistence exception we see here ?

Had no exceptions, what are you trying to do with Jsoup that it throws PersistanceException !

Hi,

Thanks for your reply. Is there any other way (without creating bundle or service) for using Jsoup API in SLing servlet ?

[sankarr26533925]

I have tested the servlet in Sling Servlet Resolver without adding the below lines and it is returning the path of servlet. If I add the below lines. it is throwing error instead of returning the path .

Parser parser = Parser.htmlParser();
            Jsoup.parse(inputHtml, "", parser);             if(parser.getErrors().size() > 0);{
                out.write("fail");
            }

Hi All,

I have created service and implementation class for using Jsoup. I am accessing service from servlet. Added the dependency in pom.xml as

             <dependency>
      <groupId>org.jsoup</groupId>
      <artifactId>jsoup</artifactId>
      <version>1.7.2</version>
      </dependency>

But  i am getting the below error in the log and bundle is not in active. "org.jsoup,version=[1.7,2) -- Cannot be resolved" is displaying in bundle.

I referred this link in this forum(http://help-forums.adobe.com/content/adobeforums/en/experience-manager-forum/adobe-experience-manage...). Still I am not getting the root cause..Please help me
